Transcript
- 0:03Speaker 1: You're listening to Why we do what we do? Welcome
- 0:16Speaker 1: to Why we do what we do. I am your
- 0:18Speaker 1: confidently ignorant host Abraham.
- 0:21Speaker 2: And I'm your diagnosing everybody after my first abnormal psychology
- 0:25Speaker 2: class host Shane Oh.
- 0:27Speaker 1: Very good. We are a psychology podcast. We talk about
- 0:29Speaker 1: the things that we do in psychology or in behavior
- 0:32Speaker 1: and the things that humans do and animals, and sometimes
- 0:35Speaker 1: we talk about things that we do badly, and one
- 0:38Speaker 1: of those things is estimating our own skills sometimes. But
- 0:42Speaker 1: this is actually a nostalgia episode. This means that we
- 0:45Speaker 1: have we previously recorded this episode on July seventeenth, twenty nineteen,
- 0:50Speaker 1: is when this was published on The Dunning Krueger Effect.
- 0:54Speaker 2: This is one of my favorite topics because it's just
- 0:57Speaker 2: so astounding how confident I will wish I had the
- 1:00Speaker 2: amount of confidence that people have when they don't know things.
- 1:05Speaker 1: Ignorance is bliss, as they say.
- 1:07Speaker 2: You know, that's what I'm thinking, like this intelligence is
- 1:10Speaker 2: a curse. Really disagree, but that's okay.
- 1:14Speaker 1: So how these work, these nostalgia episodes work is that
- 1:17Speaker 1: we are going to replay the entire original episode and
- 1:20Speaker 1: then we are going to tack on a bit of
- 1:22Speaker 1: discussion at the end, adding some new stuff for some
- 1:26Speaker 1: new takes or some new information or whatever to the
- 1:29Speaker 1: end of the episode, so that it's not just a
- 1:31Speaker 1: replay entirely, but you also get some new content as well.
- 1:35Speaker 1: I would like to say that if you're joining us
- 1:36Speaker 1: for the first time, welcome, thank you for being here.
- 1:39Speaker 1: We typically release our full length episodes on Wednesdays. We
- 1:42Speaker 1: release a sort of short form mini episode on Mondays,
- 1:46Speaker 1: and every once in a while, a few times a year,
- 1:48Speaker 1: we'll we'll release a previously recorded episode, which is the
- 1:52Speaker 1: case now. This is, as I mentioned, one that we
- 1:54Speaker 1: published originally in twenty nineteen, and we'll be expanding a
- 1:58Speaker 1: little bit on it at the end of the replay
- 2:01Speaker 1: section of this. Yes, absolutely, but before we do all
- 2:05Speaker 1: of that, it is September eleventh, which means we have
- 2:08Speaker 1: some holidays to or like days of remembrance to acknowledge,
- 2:13Speaker 1: and one of them is ye, that is September eleventh.
- 2:16Speaker 1: This is the September eleventh Day of remembering of remembrance
- 2:19Speaker 1: has been twenty four years. Twenty three years, I guess
- 2:22Speaker 1: since the original event of September eleventh, nine to eleven yep,
- 2:27Speaker 1: so worth keeping that in our minds.
- 2:30Speaker 2: It's also Emergency number Day.
- 2:33Speaker 1: That makes sense. Yeah, I want to start my own
- 2:37Speaker 1: business day. Sure, go out and do it.
- 2:40Speaker 2: Yeah, I mean sure. It's Libraries Remember Day, which is concerning,
- 2:44Speaker 2: like how much do they remember?
- 2:46Speaker 1: I was just wondering. I was like, are we supposed
- 2:48Speaker 1: to remember libraries? Or is this library is holding on
- 2:51Speaker 1: to like scandalous information.
- 2:53Speaker 2: I think that's the It's the latter to me. Oh no,
- 2:55Speaker 2: that's how I unders said that.
- 2:56Speaker 1: Oh no, Well, fortunately their knowledge stopped several decades ago
- 3:00Speaker 1: when people stopped going to libraries. So at least they're
- 3:03Speaker 1: a little outdate.
- 3:04Speaker 2: Especially here in Florida.
- 3:06Speaker 1: Yeah, they're empty now. They memories are hollow. It is
- 3:11Speaker 1: make your bed Today.
- 3:13Speaker 2: Yes it is. It's the National Day of Service and
- 3:16Speaker 2: Remembrance Day.
- 3:17Speaker 1: All of that makes a lot of sense. It's National
- 3:19Speaker 1: Emergency Responder Day. I see a theme emerging here.
- 3:23Speaker 2: Yeah, there's a few of them. It's National Hot Cross
- 3:26Speaker 2: bun Day.
- 3:27Speaker 1: It's National No News is Good News Day, which again
- 3:30Speaker 1: seem as related.
- 3:32Speaker 2: Yeah, I'd like to avoid it. I guess it's odd Day,
- 3:35Speaker 2: which is interesting because the last odd day was nine
- 3:37Speaker 2: to eleven twenty thirteen.
- 3:39Speaker 1: Wait, how could this be odd day if it's nine
- 3:41Speaker 1: eleven twenty twenty four.
- 3:43Speaker 2: I don't know that's what it said.
- 3:45Speaker 1: Okay, sure, Maybe it's just as that's what it's eleven.
- 3:48Speaker 1: It's like prime number. I don't know.
- 3:50Speaker 2: While we do some more talking about holidays, let me
- 3:52Speaker 2: look this up.
- 3:54Speaker 1: Okay, great, all right, Well related to all of the
- 3:57Speaker 1: other days that it is today. So it's nine to eleven,
- 4:02Speaker 1: Remembrance Emergency Number, Day of Service and remembrance no news
- 4:06Speaker 1: is good news, and Patriot Day and Freedom daymer remember
- 4:10Speaker 1: Freedom Day? So we have all of them all lumped together.
- 4:13Speaker 2: Yes, it's also Women's Baseball Day, which is wonderful. So
- 4:17Speaker 2: go watch what great movies?
- 4:20Speaker 1: No crime in baseball, No, there's not.
- 4:23Speaker 2: There is no evidence the odd day is real, by the.
- 4:26Speaker 1: Way, Okay, it's just odd. It happens irregularly, and that's
- 4:30Speaker 1: what makes it odd.
- 4:31Speaker 2: Yeah, I think so.
- 4:32Speaker 1: Okay, maybe it's because it was eleven years ago and
- 4:35Speaker 1: eleven is an odd number. I don't know, man, Oh,
- 4:37Speaker 1: I don't know. It is Direct Support Professional Week.
- 4:41Speaker 2: Yes, it is International Air Ambulance Week.
- 4:44Speaker 1: That is International Housekeepers Week.
- 4:47Speaker 2: Ooh, it's line dance Week as well. Terrible week.
- 4:52Speaker 1: There's this interesting stuff about line dances, and they've tried
- 4:56Speaker 1: to make that like a national dance or a state dance.
- 4:57Speaker 1: A bunch of times. It is a National Assisted Living Week.
- 5:02Speaker 2: It's National Biscuits and Gravy Week, which I love.
- 5:05Speaker 1: It is National Environmental Services Week, and.
- 5:09Speaker 2: It is National Suicide Prevention Week to go along with
- 5:12Speaker 2: Suicide Prevention Month.
- 5:14Speaker 1: It is also National Quiet Day, I found out, which
- 5:17Speaker 1: kind of makes sense.
- 5:18Speaker 2: Oh and here we are talking loudly into this thing.
- 5:22Speaker 1: I know, so loud, and it is Fair Trade Fortnite
- 5:26Speaker 1: and also apparently Sexual Health Week.
- 5:28Speaker 2: Oh great, it's so many things.
- 5:30Speaker 1: Taraji p Henson's birthday and Ludacris's birthday.
- 5:33Speaker 2: Oh good, Okay, they're both great.
- 5:37Speaker 1: Anyway, what do we do talk about the holidays? I
- 5:40Speaker 1: know there's a lot going on today and this week
- 5:42Speaker 1: and this month.
- 5:43Speaker 2: Uh huh.
- 5:44Speaker 1: Apparently I didn't know this, but September is the most
- 5:47Speaker 1: popular birth month. Most people are born in September.
- 5:49Speaker 2: Yeah, everybody's bringing in the new year with a bang,
- 5:52Speaker 2: if you know what I mean. Happy Sex Health Week.
- 6:00Speaker 1: Right, Yeah, we do talk about these holidays for sort
- 6:03Speaker 1: of fun thing to do, but also what we come
- 6:05Speaker 1: here to do is talk about psychology things, which I
- 6:07Speaker 1: think that I said before. But we are a college podcast, Yes,
- 6:11Speaker 1: but we are. We're visiting this episode abobout the Dunning
- 6:14Speaker 1: Kruger effect, one of the more well I think, more
- 6:16Speaker 1: popular and well known about effects in all of psychology.
- 6:20Speaker 1: I would guess, I think so.
- 6:22Speaker 2: But I mean that's us thinking that we know more
- 6:25Speaker 2: about this than we do.
- 6:27Speaker 1: That's a very good point. Yeah, I should not be
- 6:29Speaker 1: so confident in my assumptions here. But what we're going
- 6:33Speaker 1: to do is we're going to go ahead and jump
- 6:35Speaker 1: into this episode. We're going to play it in its entirety,
- 6:37Speaker 1: and then at the end we're going to come back
- 6:38Speaker 1: and we're going to add a little bit of context.
- 6:40Speaker 1: I already said all of that, but just as a
- 6:41Speaker 1: reminder before I do that, I will tell you really
- 6:44Speaker 1: quick that if you like what you hear today and
- 6:45Speaker 1: would like to support us, you can join us on Patreon,
- 6:47Speaker 1: pick up some merch, leave us a rating and review,
- 6:49Speaker 1: like subscribe, tell a friend, maybe invent a psychological construct
- 6:54Speaker 1: and then name it after us if it's a positive
- 6:58Speaker 1: information disseminating one. Yeah, but that's what we're doing here.
- 7:02Speaker 1: So anyway, please enjoy this now five year old episode
- 7:05Speaker 1: about the Dunning Krueger effect, and then at the end
- 7:08Speaker 1: we will update you on some new stuff that we've found.
- 7:17Speaker 1: All right, this is Abraham and this is Shane. So
- 7:19Speaker 1: welcome to Why We Do What We Do.
- 7:21Speaker 2: Your favorite consumable psychology podcast.
- 7:24Speaker 1: All right, Shane, we need to just jump right into
- 7:26Speaker 1: this because I have a story I'm very excited to
- 7:28Speaker 1: tell you, and audience, I'll tell you this is so
- 7:32Speaker 1: far my favorite story that I've been able to tell.
- 7:35Speaker 1: So I hope I do a justice. I don't want
- 7:36Speaker 1: to overhype it too much, but I think I think
- 7:38Speaker 1: it'll be fun. Okay, So let's set the stage for
- 7:41Speaker 1: someone whose name is MacArthur Wheeler. And maybe you've already
- 7:44Speaker 1: heard the story. Maybe not, but it's a great name
- 7:46Speaker 1: to begin with. Already, MacArthur Wheeler. Yeah, it's nineteen ninety four,
- 7:51Speaker 1: nineteen ninety five, and we're in Pittsburgh, Pennsylvania. Great yeah,
- 7:55Speaker 1: great city, and we're going to imagine here that. So
- 7:58Speaker 1: we've got little MacArthur. I'm not entirely sure how old
- 8:01Speaker 1: he is at this point. He's probably in his mid
- 8:03Speaker 1: twenties or so, and maybe he's got this older brother
- 8:06Speaker 1: who is like communicating with people through these pieces of paper,
- 8:09Speaker 1: and MacArthur's like, I'm going to find out what's going
- 8:11Speaker 1: on here. So he grabs a piece of paper and
- 8:13Speaker 1: it's completely blank, and he later learns that there was
- 8:16Speaker 1: a hidden message on the piece of paper that was
- 8:18Speaker 1: written in invisible ink. Now I just made up all
- 8:20Speaker 1: that stuff about his brother. I have no idea, but
- 8:21Speaker 1: either way, he learned about this idea that messages can
- 8:24Speaker 1: be hidden on piece of paper by writing them in
- 8:26Speaker 1: lemon juice. Right, you write them on lemon juice, and
- 8:30Speaker 1: what happens is that the lemon juice just blends right
- 8:32Speaker 1: into the paper, looks like it's not even there. And
- 8:34Speaker 1: then what happens is if you hold that paper over
- 8:37Speaker 1: some kind of light or heating sore. It's probably not
- 8:39Speaker 1: like a flame because it'll just burn the paper. Paper
- 8:41Speaker 1: is pretty flammable. You hold over something like low low heat,
- 8:45Speaker 1: like a light, what it does is that it'll actually
- 8:48Speaker 1: oxidize the lemon juice and it'll turn the juice brown,
- 8:51Speaker 1: and then it can now be read. So that's this
- 8:53Speaker 1: whole idea of the invisible ink sort of where that
- 8:57Speaker 1: one way that where that comes from? Okay, Okay, the
- 9:00Speaker 1: budding scientist that MacArthur Wheeler was, he was intrigued and
- 9:03Speaker 1: inspired the power that the lemons had to create this
- 9:07Speaker 1: invisible ink, right, And unfortunately he then found himself pretty
- 9:12Speaker 1: soon after that in a situation where he really needed
- 9:15Speaker 1: some cash. I'm guessing to pay off his espionage and
- 9:18Speaker 1: scientific training, because he's just you know, he's intrigued in
- 9:21Speaker 1: these things, of course, But regardless of whatever it was,
- 9:23Speaker 1: he found that he really needed some cash, and so
- 9:25Speaker 1: he decided to go out and buy a bunch of
- 9:27Speaker 1: lemons because he had a plan. And so on April nineteenth,
- 9:31Speaker 1: nineteen ninety five, the middle of the day, Wheeler walks
- 9:34Speaker 1: into a bank, pulls out a gun, and demands the money.
- 9:37Speaker 2: So did he squirt lemons juice in their eyes or something?
- 9:40Speaker 1: No?
- 9:40Speaker 2: Okay, so I need to know how these lemons work, Like,
- 9:43Speaker 2: what's the deal with the lemons?
- 9:44Speaker 1: I'm getting there. But he wasn't done yet. After he
- 9:47Speaker 1: robs that bank, he goes into another bank and does
- 9:50Speaker 1: the exact same thing, not scorting lemons, just in their eyes,
- 9:53Speaker 1: but he has purched all these lemons. We'll get to
- 9:55Speaker 1: in a moment. Now. Interestingly, the bankers may have been
- 9:57Speaker 1: a little bit confused at how much Wheeler was was
- 10:00Speaker 1: sort of cringing and blinking while he's there, and we'll
- 10:03Speaker 1: come into this, Okay, So why are the lemons relevant? Well,
- 10:07Speaker 1: MacArthur was not actually wearing any kind of mask or
- 10:09Speaker 1: disguise or hiding his voice or face in any way whatsoever.
- 10:13Speaker 1: And it's the middle of the day, on regular day
- 10:15Speaker 1: of week. And I mean it's nineteen ninety five, which
- 10:19Speaker 1: at this point was quite a while ago. But even
- 10:21Speaker 1: back then, banks had security cameras, and in fact, Wheeler
- 10:24Speaker 1: knew that they had security cameras. Interestingly, then the police,
- 10:28Speaker 1: of course see the security footage that identify who the
- 10:31Speaker 1: person is who robbed these banks, and they arrive at
- 10:33Speaker 1: his home to arrest him, and they even show him
- 10:35Speaker 1: some of the videos, saying like, you robbed a bank.
- 10:39Speaker 1: Here's a video of you robbing the bank, and what
- 10:41Speaker 1: do you think that he maybe said.
- 10:43Speaker 2: Oh, I'm I could imagine he would say something like
- 10:47Speaker 2: how did you know it was me? Or like how
- 10:49Speaker 2: did you see me?
- 10:50Speaker 1: Yeah, you're actually not as far off as I thought
- 10:52Speaker 1: you might be. What he said is, but I wore
- 10:53Speaker 1: the juice, and the police here are kind of confused
- 11:00Speaker 1: by that. Response is you might imagine you see and
- 11:03Speaker 1: you maybe figured this out as I was talking about it.
- 11:05Speaker 1: MacArthur Wheeler reasoned that because this lemon juice can can
- 11:09Speaker 1: work to make invisible ink, it must be the properties
- 11:12Speaker 1: of lemons that grant this invisibility. And so he explains
- 11:16Speaker 1: to the police that he had rubbed lemon juice all
- 11:18Speaker 1: over his face before robbing the banks because the lemon juice,
- 11:21Speaker 1: he believed made him invisible. Oh that there was no
- 11:29Speaker 1: way people could identify him and the cameras wouldn't be
- 11:32Speaker 1: able to see him because he would be invisible because
- 11:34Speaker 1: he juice on his face.
- 11:37Speaker 2: That is one of the best things I've ever heard.
- 11:40Speaker 1: And so, of course, at first, the very first thing
- 11:42Speaker 1: he said is if he says, okay, I rubbed lemon
- 11:45Speaker 1: juice on my face, then the cops sort of thought
- 11:46Speaker 1: maybe he's on drugs, or maybe he's drunk or something.
- 11:49Speaker 1: Not totally sure.
- 11:50Speaker 2: No, he was not.
- 11:52Speaker 1: He was just that wrong. He apparently even said that
- 11:55Speaker 1: he had tested it by taking a picture of himself
- 11:58Speaker 1: with lemon juice on his face and claimed that he
- 12:00Speaker 1: couldn't see himself in the picture really, which leads me
- 12:03Speaker 1: to speculate a little bit in terms of what may
- 12:05Speaker 1: have happened here that that would have been the effect.
- 12:08Speaker 1: My first guess is that he actually had the camera
- 12:10Speaker 1: pointed away from him, and so that when he took
- 12:12Speaker 1: the picture and he wasn't in it, it's because the
- 12:15Speaker 1: camera wasn't pointed at him at all. My second guess
- 12:20Speaker 1: is that he did point the camera toward him, but
- 12:22Speaker 1: pointed it so far out of the way that he
- 12:23Speaker 1: couldn't actually see himself. And my third guest, I don't
- 12:25Speaker 1: actually even know what else could be another option here.
- 12:27Speaker 1: Those are to make any sense.
- 12:29Speaker 2: That's amazing, I know now.
- 12:32Speaker 1: Hilariously, he even and as I mentioned before, he reported
- 12:36Speaker 1: that the lemon juice had made the robberies difficult because
- 12:38Speaker 1: the lemon juice had been getting in his eyes and
- 12:40Speaker 1: they was stinging his eyes as he was trying to
- 12:42Speaker 1: rout them.
- 12:43Speaker 2: That's why he's blinking.
- 12:44Speaker 1: Exactly, That's why he was blinking and cringing. He was
- 12:47Speaker 1: easily convicted and sent to jail, as you might imagine.
- 12:50Speaker 2: Oh my god, that's one of the best things I've
- 12:52Speaker 2: ever heard, Like legitimately, so how wait, so how does
- 12:54Speaker 2: he explain lemonade?
- 12:56Speaker 1: I know, right? And I also was thinking. I was
- 13:01Speaker 1: thinking of, like, do you really believe that you're the
- 13:03Speaker 1: first person in all of human history if this had
- 13:05Speaker 1: if this had been true, let's like lemons actually make
- 13:07Speaker 1: you invisible. You're the first person in human history to
- 13:09Speaker 1: figure this out and try and use it for nefarious reasons,
- 13:12Speaker 1: Like wouldn't armies be like growing lemon orchards and like
- 13:17Speaker 1: gigantic acres to cover their soldiers in lemon juice so
- 13:20Speaker 1: that they could like going right on the territory? Like
- 13:24Speaker 1: who wouldn't have done capitalized on this if that was
- 13:26Speaker 1: the thing? Yeah, soldiers from Florida would have been unstoppable.
- 13:30Speaker 1: There's so much citrus here, the Floridian soldiers, that's right. Yeah,
- 13:34Speaker 1: maybe it's just citrus generally speaking. Maybe even eating it
- 13:37Speaker 1: makes you invisible. I don't know.
- 13:38Speaker 2: So that's amazing, all right.
- 13:40Speaker 1: So anyway, yeah, I just had to share that story.
- 13:43Speaker 1: And this is actually gonna factor and even more relevant
- 13:45Speaker 1: when we start talking about what we're talking about today,
- 13:47Speaker 1: which I haven't announced yet, but we're gonna get to
- 13:49Speaker 1: in just a moment. First, moving on from the exciting
- 13:53Speaker 1: story that we just told chain. How good of a
- 13:55Speaker 1: driver do you think you are compared to other drivers?
- 13:57Speaker 2: I think I'm a pretty good driver, like I think,
- 13:59Speaker 2: I think it depends on your definition of good. I
- 14:01Speaker 2: would argue that I'm a very safe driver.
- 14:03Speaker 1: Okay, fair enough. Did you know that I'm giving you
- 14:07Speaker 1: the statistics a little bit wrong here? But it's something
- 14:09Speaker 1: like ninety percent of people believe that they are better
- 14:11Speaker 1: drivers than ninety percent of people.
- 14:14Speaker 2: That's amaz. That's so ninety percent of people think they're
- 14:18Speaker 2: they're they're in the top ten percent of good drivers.
- 14:21Speaker 1: Yes, I have been surveyed. That is to say that
- 14:25Speaker 1: people kind of radically overestimate how good of a driver
- 14:29Speaker 1: they really are, right, Yeah, And I have a story
- 14:31Speaker 1: about myself as well. I think the theme is starting
- 14:33Speaker 1: to become a little bit more clear here as we're
- 14:35Speaker 1: going through this. But when I was learning to play
- 14:39Speaker 1: the drums, I remember thinking that I was the greatest
- 14:43Speaker 1: thing ever at it. And then I started listening to
- 14:47Speaker 1: really really good drummers and I started learning really really
- 14:50Speaker 1: difficult music and discovered I'm not that good at playing
- 14:54Speaker 1: the drums at least when I was picking up and
- 14:56Speaker 1: I certainly got a lot better. But certainly I'm not
- 14:58Speaker 1: in like the top ten drummers of all time. I just,
- 15:00Speaker 1: you know, was I got proficient enough that I could
- 15:03Speaker 1: I could play the drums well and would be able
- 15:06Speaker 1: to navigate them like anybody who spend a lot of
- 15:09Speaker 1: time learning to play the drums. And then another one
- 15:13Speaker 1: example for myself is coming right out of undergrad I
- 15:16Speaker 1: believe that I knew just about everything that there was
- 15:19Speaker 1: to know in the field that I had studied in.
- 15:22Speaker 1: And then I went to graduate school, Yeah, and realized
- 15:24Speaker 1: that I knew very very little. And the longer I
- 15:28Speaker 1: was in graduate school, the more I realized how little
- 15:32Speaker 1: I really knew about the scope and depth of the
- 15:36Speaker 1: field that I belonged to. And I feel like I've
- 15:39Speaker 1: heard the story from other people as well that the
- 15:41Speaker 1: more you know, the more you realize how little you know.
- 15:44Speaker 1: And that's kind of a thing. There's so many good
- 15:47Speaker 1: examples of this that I think if you look at
- 15:51Speaker 1: Steve Carell's character on the American version of the Office,
- 15:54Speaker 1: he plays Michael Scott, He's someone who often seems to
- 15:57Speaker 1: think that he knows a lot about things and makes
- 15:59Speaker 1: hilariously stupid mistakes because he thinks he knows too much.
- 16:04Speaker 1: The character Jason on the show The Good Place is
- 16:07Speaker 1: also someone who is portrayed as being incredibly stupid, but
- 16:10Speaker 1: like is overly confident that they describe as having massively
- 16:15Speaker 1: unearned confidence and just thinking that he knows a lot
- 16:18Speaker 1: about what he's going to do, and he ends up
- 16:20Speaker 1: This is sort of a spoiler if you haven't seen
- 16:22Speaker 1: the show, so skip ahead about ten seconds. But he
- 16:24Speaker 1: ends up dying because he locks himself in a safe
- 16:27Speaker 1: while wearing a scuba mask, thinking that the scuba mask
- 16:30Speaker 1: is going to help him breathe while he's in the safe,
- 16:33Speaker 1: even though it's not. There's no air hole out of
- 16:35Speaker 1: the safe or anything. And then there's a story I
- 16:37Speaker 1: just mentioned about MacArthur Wheeler. There's this effect that people
- 16:41Speaker 1: will speak with conviction, loudly, emotionally and with authority and
- 16:45Speaker 1: boisterous claims, unconcerned about how little they really know about something.
- 16:49Speaker 1: And it turns out that this effect that I've been
- 16:51Speaker 1: describing for the last ten minutes and in great detail
- 16:54Speaker 1: actually has a name. And interestingly, and this was just
- 16:58Speaker 1: a coincidence, but this year just happens to be the
- 17:00Speaker 1: twenty year anniversary of the publication of this effect, and
- 17:03Speaker 1: I want to make sure, because we're talking about this,
- 17:06Speaker 1: that we were careful to avoid sounding like we know
- 17:08Speaker 1: too much about this and for today's discussion, so that
- 17:11Speaker 1: we avoid falling victim to the tendency to overestimate how
- 17:15Speaker 1: much we really know about this. And this is called
- 17:17Speaker 1: the Dunning Krueger effect.
- 17:19Speaker 2: Okay, yes, I feel like this, Like being on this
- 17:23Speaker 2: podcast has made me realize how little I know. So
- 17:25Speaker 2: thankfully I'm self aware enough to recognize that this effect
- 17:29Speaker 2: is pretty interesting to see. Like you see people really
- 17:32Speaker 2: really dig into stuff, and you're like, that is not
- 17:34Speaker 2: even close to accurate.
- 17:36Speaker 1: Yeah. Absolutely, So this falls under what a category of
- 17:40Speaker 1: what might be called cognitive bias. And so this is
- 17:42Speaker 1: essentially a thing that people often tend to do that
- 17:46Speaker 1: is biased toward a particular I guess tendency that may
- 17:51Speaker 1: or may not well in this case, is not accurate.
- 17:53Speaker 1: Usually we talk about these types of cognitive biases, they
- 17:56Speaker 1: tend to be something that is a mistake in a
- 17:59Speaker 1: way of thinking or sort of a logical error in
- 18:02Speaker 1: one's thinking. And one of the foundational pieces about the
- 18:06Speaker 1: Dunning Kruger effect is another psychological process or bias called
- 18:10Speaker 1: confirmation bias, and this is basically what it sounds like, Okay, Essentially,
- 18:15Speaker 1: the gist of this is that we can't possibly know
- 18:17Speaker 1: everything in the world, so we learn about you know,
- 18:20Speaker 1: we learn what we can as much as we can
- 18:22Speaker 1: when we can, and we we can be fairly selective
- 18:26Speaker 1: and what we choose to learn while still spending a
- 18:28Speaker 1: lot of time and effort on that sliver of information
- 18:31Speaker 1: that we chose to take on. Now, because of this,
- 18:33Speaker 1: we can have the impression that we have really done
- 18:36Speaker 1: our due diligence and learning about our topic of interest.
- 18:40Speaker 1: And confirmation bias is when we then look for information
- 18:43Speaker 1: that confirms our pre existing beliefs, and we ignore or
- 18:46Speaker 1: dismiss any irrelevant information that contradicts our pre existing beliefs,
- 18:51Speaker 1: and we only recall in a way that allows us
- 18:53Speaker 1: to feel more correct about those beliefs. And so the
- 18:56Speaker 1: reason that these are related is because as we go
- 18:59Speaker 1: about learning things, as I said, we're gonna just sort
- 19:01Speaker 1: of we have to choose what we're going to learn.
- 19:04Speaker 1: There are some things about which we can learn everything
- 19:06Speaker 1: there is to know, but there are a lot of
- 19:08Speaker 1: things that we can't. And so when we only choose
- 19:11Speaker 1: those things that confirm the beliefs that we already have,
- 19:14Speaker 1: then we are falling victim to that confirmation by us.
- 19:18Speaker 1: A very clear example of this are the flat earthers.
- 19:21Speaker 2: Oh, flat earthers, Yeah, and it's they have members all
- 19:24Speaker 2: around the globe. Did you know that?
- 19:26Speaker 1: That's right? I remember you telling me that, And I
- 19:30Speaker 1: had recently watched the documentary that is at the time
- 19:33Speaker 1: of this recording on Netflix called Beyond the Curve, which
- 19:36Speaker 1: is a great documentary, and in this you see this
- 19:39Speaker 1: so clearly, where there is an abundance of information that
- 19:44Speaker 1: the Earth is not flat so much that I don't
- 19:47Speaker 1: I can't really wrap my head around the position that
- 19:49Speaker 1: they take, but they will specifically ignore all of that,
- 19:52Speaker 1: downplay it, give it some very bizarre explanation for how
- 19:58Speaker 1: it's the case, and the only will accept information that
- 20:01Speaker 1: confirms their pre existing opinion. UFO hunters, same exact thing.
- 20:07Speaker 2: Yeah, And like in visiting mediums, and there's there's a
- 20:09Speaker 2: lot of different and those are I feel like these
- 20:12Speaker 2: examples of people that seem like they have like more
- 20:14Speaker 2: outlandish types of beliefs, like we talk about like ghost
- 20:17Speaker 2: hunters and stuff like that, and how it it kind
- 20:19Speaker 2: of like perpetuates Bigfoot, like all the cryptozoology stuff like,
- 20:22Speaker 2: which is really interesting to see, but it's not like
- 20:26Speaker 2: what ends up happening is people kind of talking the
- 20:28Speaker 2: echo chamber, right Like they kind of like they collaborate
- 20:30Speaker 2: and they corroborate with people that share those same opinions,
- 20:33Speaker 2: and they kind of back and forth confirm each other
- 20:35Speaker 2: and then and eventually it turns into this big thing.
- 20:37Speaker 2: And these are kind of more like funny or like
- 20:41Speaker 2: less harmful I would say, types of examples. But you
- 20:45Speaker 2: see this in like American politics right now, very specifically,
- 20:48Speaker 2: nobody can have like a conversation about discourse when you're
- 20:52Speaker 2: talking about different political ideologies, Like nobody can really have
- 20:55Speaker 2: that conversation because of they speak in these echo chambers
- 20:58Speaker 2: and they kind of confirm their own things, even though
- 21:00Speaker 2: data might present something else.
- 21:02Speaker 1: Yeah, I mean, you see people who will make arguments
- 21:04Speaker 1: foreign against immigration, and they will only accept information that
- 21:07Speaker 1: confirms their opinion about that thing, or foreign against GMOs
- 21:11Speaker 1: or foreign against vaccines, and like some of these things
- 21:14Speaker 1: there are relatively clear there's relatively clear scientific information that
- 21:17Speaker 1: backs up those things. Now, all of this is just
- 21:19Speaker 1: talking about confirmation by us, cause we need to get
- 21:21Speaker 1: into the actual Dunning Kruger effect thing. But the point
- 21:23Speaker 1: of this is that this tends to be pretty emotionally
- 21:25Speaker 1: charged and often about these controversial topics, as you had mentioned,
- 21:28Speaker 1: and so people will get when they're that emotionally invested
- 21:33Speaker 1: in something, then they will absolutely dig in their heels
- 21:36Speaker 1: and put their backs up against the wall in terms
- 21:39Speaker 1: of refusing to admit an alternative their position.
- 21:42Speaker 2: Absolutely, and it just kind of snowballs from there. So
- 21:44Speaker 2: it becomes a little bit of a problem because then
- 21:47Speaker 2: they just kind of like their opinion flies in the
- 21:49Speaker 2: face of are you like their perceived facts fly in
- 21:52Speaker 2: the face of, like, what's the actual truth?
- 21:54Speaker 1: Before we talk about whatever, the next thing will be,
- 21:57Speaker 1: let's do some ads, all right, getting back to what
- 22:06Speaker 1: we're doing. So let's go ahead and get into the
- 22:08Speaker 1: background of the Dunning Krueger effect. Now, if you were
- 22:11Speaker 1: to actually read the original article, the very first paragraph
- 22:14Speaker 1: describes the story about MacArthur Wheeler, and so there is
- 22:18Speaker 1: I saw some sources that actually indicated that the entire
- 22:21Speaker 1: research line that was spawned by the Dunning Krueger effect
- 22:24Speaker 1: was in fact inspired by the incredible level of confidence
- 22:27Speaker 1: that MacArthur Wheeler must have had when he went into
- 22:30Speaker 1: rob those banks. And so these two psychologists Dunning nan
- 22:33Speaker 1: Krueger I'll talk about more in a second, they actually
- 22:35Speaker 1: set out to do some experiments on this effect of
- 22:38Speaker 1: this sort of high confidence low competence in human bias
- 22:42Speaker 1: that led to Wheeler's unfortunate decision. Now, about four years
- 22:46Speaker 1: after Wheeler's story, so we're now in nineteen ninety nine,
- 22:48Speaker 1: we have doctor David Dunning, and he deigned to disseminate
- 22:52Speaker 1: with his graduate student at the time, graduate student Justin Krueger,
- 22:56Speaker 1: and they published a paper outlining the effect that was
- 22:59Speaker 1: a observed with respect to this overconfidence thing.
- 23:03Speaker 2: Yeah, and so this paper that they put out in
- 23:04Speaker 2: nineteen ninety nine was called Unskilled and Unaware of It
- 23:07Speaker 2: how difficulties in recognizing one's own incompetence lead to inflated
- 23:11Speaker 2: self assessments, which is just such a great it's a
- 23:15Speaker 2: great title.
- 23:16Speaker 1: Isn't that so good? Like it's so good. Scientific papers
- 23:19Speaker 1: do not need to have these boring and dull titles
- 23:21Speaker 1: like that. This is like one of the most highly
- 23:23Speaker 1: cited publication ever and has this awesome title.
- 23:28Speaker 2: So have you seen that thing? In academia where you
- 23:31Speaker 2: say Harry Potter and the and that's like a new movie,
- 23:34Speaker 2: like Harry Potter and the Unskilled and Unaware of it,
- 23:36Speaker 2: how difficult, Like this one doesn't fit as well, but
- 23:38Speaker 2: some of them do, and you're like, oh, that's good, No,
- 23:40Speaker 2: that's awesome.
- 23:41Speaker 1: I love it.
- 23:41Speaker 2: Harry Potter and the self assessment of incompetence among those
- 23:44Speaker 2: with Dunning Krueger effect, Like you know, you might do
- 23:46Speaker 2: something like that. It's pretty cool.
- 23:48Speaker 1: There you go. All right, So this effect, as it's
- 23:51Speaker 1: clear now, and as I mentioned earlier, has become famous
- 23:53Speaker 1: and known appropriately enough as the Dunning Krueger effect, and
- 23:57Speaker 1: their original paper described four experiments used to examine the effect.
- 24:01Speaker 1: So let's go ahead and dive into those experiments, all right.
- 24:04Speaker 2: So as part of these four experiments, they tested humor, grammar,
- 24:07Speaker 2: logical and calibrating competence. So they kind of tested all
- 24:10Speaker 2: these things. And in the first experiment, sixty five participants
- 24:13Speaker 2: were asked how good they were judging whether or not
- 24:16Speaker 2: something could be perceived as funny, which is great because
- 24:19Speaker 2: I think things are hilarious, so that I would be
- 24:21Speaker 2: a participant in this, and then asked to do that
- 24:24Speaker 2: very thing. So those participants who presume to be among
- 24:27Speaker 2: the greatest judges of humor performed worse than all the
- 24:30Speaker 2: other participants, whereas those that guessed that they weren't exceptional
- 24:33Speaker 2: judges but were actually pretty knowledgeable about the content, they
- 24:37Speaker 2: actually performed pretty well, at least closer to that predicted
- 24:40Speaker 2: level across subjects.
- 24:41Speaker 1: Yeah, now I think you might be able to look
- 24:44Speaker 1: at this and immediately recognize, well, humor's pretty subjective, and
- 24:46Speaker 1: whether or not someone does well at being funny is
- 24:49Speaker 1: going to depend on their audience and various other sort
- 24:52Speaker 1: of subjective interpretations. And the authors recognize this, and so,
- 24:55Speaker 1: concerned with that subjectivity of something like humor and interested
- 24:59Speaker 1: in seeing whether they could replicate those results with the
- 25:02Speaker 1: different group, they chose a more sort of objective test
- 25:05Speaker 1: to try their experiment again in a different domain, so
- 25:08Speaker 1: an experiment too. They had forty five undergraduate students, of course,
- 25:11Speaker 1: because where else would you get your population from, right,
- 25:14Speaker 1: And they told those students that they were taking a
- 25:16Speaker 1: logic slash reasoning test, and then after the test they
- 25:19Speaker 1: were asked to estimate their logic slash reasoning ability compared
- 25:22Speaker 1: to the other students specifically, so how well do you
- 25:25Speaker 1: think that you did compared to the other students who
- 25:27Speaker 1: would also take this test? And also how well they
- 25:30Speaker 1: did compare to other people taking the test, and how
- 25:32Speaker 1: many of the answers they actually got correctly. So they
- 25:35Speaker 1: were like, how good do you think you are logic reasoning?
- 25:37Speaker 1: How much better at this do you think? Or how
- 25:39Speaker 1: well do you think you did this compared to other students?
- 25:41Speaker 1: How many do you think you got correct Those are
- 25:43Speaker 1: sort of the three ways that they asked them this
- 25:45Speaker 1: that it produced one of the most famous graphs ever. Actually,
- 25:47Speaker 1: all of these experiments have for very similar graphs, but
- 25:49Speaker 1: this is this one in particular I saw being used
- 25:51Speaker 1: in other publications elsewhere, and which is clearly observed that
- 25:55Speaker 1: on average, participants righting themselves at least on par with
- 25:58Speaker 1: much more competence to students and then performed at the
- 26:02Speaker 1: bottom twenty twenty fifth percentile, the bottom quartile of the
- 26:05Speaker 1: entire distribution, whereas students who were more competent actually rated
- 26:08Speaker 1: themselves about the same and even in some cases less
- 26:11Speaker 1: than those other students than the least competent performers, and
- 26:14Speaker 1: they actually did much better than they guessed that they
- 26:16Speaker 1: would do. So those people who What you saw is
- 26:19Speaker 1: that people rated themselves fairly similarly in terms of what
- 26:22Speaker 1: they expected, but the highest performers actually really outperformed where
- 26:25Speaker 1: they rated themselves, and the lowest performers way overestimated how
- 26:29Speaker 1: well their performance was. Now, those people that did know
- 26:33Speaker 1: quite a bit more about the subject, they were closer
- 26:35Speaker 1: to their actual performance, but they still did underrate themselves
- 26:38Speaker 1: a little bit.
- 26:39Speaker 2: I love that. It just speaks to the idea that, like,
- 26:42Speaker 2: besides the fact that people overestimate their competence, that there
- 26:45Speaker 2: are people who are competent that way underestimated too. Like
- 26:48Speaker 2: I liked that there's that other side of the coin.
- 26:50Speaker 2: But I think that's pretty interesting. I feel like that's
- 26:52Speaker 2: probably where maybe the discussion around imposter syndrome get sparked
- 26:55Speaker 2: a little bit, Like ooh, I like that. You know. So,
- 26:57Speaker 2: Experiment three followed basically the same format, and this time
- 27:00Speaker 2: with eighty four undergrad participants, so they had a pretty
- 27:03Speaker 2: big pool of undergrads. That's great, like, yeah, right, lucky
- 27:06Speaker 2: for them. And so the results were very similar to
- 27:09Speaker 2: the first two tests, and they need to follow up
- 27:11Speaker 2: that they called takes one to know One.
- 27:13Speaker 1: I just love their titles. They're so good.
- 27:15Speaker 2: I love that they're like just very like they're just
- 27:17Speaker 2: very human scientists. Like that's so great.
- 27:19Speaker 1: Yeah, in the takes one to know.
- 27:21Speaker 2: One follow up, What they did was they asked the
- 27:24Speaker 2: lowest and highest performing students to grade these tests from
- 27:27Speaker 2: other students by answering how many they thought the other
- 27:29Speaker 2: students had answer correctly, that's that's so good, right, is
- 27:33Speaker 2: that clever? And then they received their own tests back
- 27:37Speaker 2: and were asked to guess how well they performed relative
- 27:40Speaker 2: to the test they had graded.
- 27:41Speaker 1: So this one's just getting a little bit deeper dive
- 27:44Speaker 1: on how people would rate themselves in comparison to others
- 27:49Speaker 1: and giving them sort of another way of looking at it.
- 27:52Speaker 1: When they not only do they just guess how well
- 27:54Speaker 1: they performed, but they actually look at other performance and
- 27:56Speaker 1: then try and guess how well they perform.
- 27:58Speaker 2: This is such a deep dive. This is so great.
- 28:01Speaker 2: So the low performers increased their perceived performance of themselves
- 28:04Speaker 2: on average, unable to recognize their own weaknesses, and became
- 28:08Speaker 2: even less accurate at gauging their abilities. So they found
- 28:11Speaker 2: that like those people who are low performers were still
- 28:13Speaker 2: not able to recognize their own weaknesses well, and they.
- 28:16Speaker 1: Almost doubled down on it too, So they went from
- 28:18Speaker 1: like they already thought that they were pretty hot stuff.
- 28:22Speaker 1: Then they looked at everyone else's tests incidentally, some of
- 28:25Speaker 1: those tests where people did much better than they did,
- 28:27Speaker 1: and then they're like, wow, I really am a genius
- 28:29Speaker 1: and thought they were even better after that, even though
- 28:32Speaker 1: these were the low like these are the bottom twenty
- 28:34Speaker 1: fifth percentile performance wise.
- 28:36Speaker 2: Right, And then the high performers did also increase their
- 28:40Speaker 2: personal estimations as well because they could better calibrate their
- 28:43Speaker 2: performance and became more accurate in their ability to gauge
- 28:46Speaker 2: their performance. So the higher performance were able to kind
- 28:48Speaker 2: of get closer to that that mark.
- 28:51Speaker 1: Right, So they would they sort of undersold themselves initially,
- 28:54Speaker 1: but then as they got to actually compare their performance
- 28:56Speaker 1: to others, they had a better system by which they
- 28:59Speaker 1: could actually evaluate their own performance because they had the
- 29:03Speaker 1: appropriate level of competence needed to make that estimation, whereas
- 29:08Speaker 1: otherwise they tend to guess pretty conservatively. Now that they
- 29:10Speaker 1: have more information, they can make a good educated guess.
- 29:13Speaker 1: Low performers, on the other hand, are like straight out
- 29:15Speaker 1: of idiocracy. They're like, I am flying high because the
- 29:19Speaker 1: world is my oyster, and like, even though they're wrong
- 29:21Speaker 1: about basically everything, they're like, I'm gonna stick to my
- 29:24Speaker 1: guns because I can. And that was not a comment
- 29:28Speaker 1: on firearms, by the way. That was stick to my
- 29:30Speaker 1: guns as then holding the ground. But all right, yeah,
- 29:33Speaker 1: finally an experiment for I honestly was not trying to
- 29:37Speaker 1: make upun there. I was legitimately concerned that people thought
- 29:39Speaker 1: I was making a political statement. Anyway. An experiment for
- 29:42Speaker 1: this was essentially another type of logic test. This time
- 29:45Speaker 1: they got up to one hundred and forty undergraduate students
- 29:48Speaker 1: and basically had the same results as before. So essentially
- 29:51Speaker 1: they replicated this three times. They got four different studies
- 29:54Speaker 1: showing about the same thing. With respect to those people
- 29:58Speaker 1: who when they had a high level of confidence, they
- 30:02Speaker 1: would vastly overestimate how well they actually were at performing,
- 30:06Speaker 1: Dunning said, quote, ignorant people do not recognize scratch that
- 30:10Speaker 1: cannot recognize just how incompetent they are. End quote, And
- 30:14Speaker 1: so he's sort of encapsulating the effects here. He also
- 30:17Speaker 1: had a few more quotes. I really liked that. I'm
- 30:19Speaker 1: actually not sure that these were all from the article.
- 30:21Speaker 1: I found these in various places, and I just kind
- 30:22Speaker 1: of grabbed him as I saw them because they all
- 30:24Speaker 1: were so good. Another quote, and his name was doctor
- 30:27Speaker 1: David Dunning. Again, just to make sure people are out there,
- 30:29Speaker 1: he said. Quote. What's curious is that in many cases,
- 30:32Speaker 1: incompetence does not leave people disoriented, perplexed, or cautious. Instead,
- 30:36Speaker 1: the incompetent are often blessed with an inappropriate confidence, booed
- 30:40Speaker 1: by something that feels to them like knowledge. End quote.
- 30:46Speaker 2: That's so I love I love how It's just it's
- 30:51Speaker 2: basically just saying, like stupid people. I shouldn't say stupid.
- 30:54Speaker 2: They're not stupid because these could be smart people. They
- 30:56Speaker 2: just are so let me let me rephrase that. People
- 30:59Speaker 2: that that literally don't know about a particular bit of
- 31:04Speaker 2: information will like lean so heavily into something that they
- 31:07Speaker 2: feel like is knowledge, Like that they feel like they
- 31:09Speaker 2: know it. They lean so hard into it. They're not like, nah,
- 31:13Speaker 2: maybe I don't know.
- 31:15Speaker 1: I had an idea for a shirt for why we
- 31:17Speaker 1: do what we do that was looked like a multiple
- 31:20Speaker 1: choice test, and it was like they answered almost every
- 31:22Speaker 1: question and one of the options was it feels right,
- 31:26Speaker 1: and I was like, incorrect, that's never a lot of
- 31:30Speaker 1: what this is right, Yeah, exactly is Yeah, you'll have
- 31:33Speaker 1: those people who like, well it makes logical or an
- 31:36Speaker 1: intuitive sense, or it feels rights to me, It has
- 31:38Speaker 1: that truthiness thing to it to have it be this way.
- 31:41Speaker 1: So I'm going to lean into this full tilt and
- 31:45Speaker 1: really hold my ground. And although they didn't, the study
- 31:48Speaker 1: was not designed to show this one effect specifically. The
- 31:51Speaker 1: fact that I'm about to say is that what often
- 31:53Speaker 1: happens is that when someone declares a position on something,
- 31:57Speaker 1: they will often find themselves compelled to defend that position
- 32:00Speaker 1: tooth and nail, even though they have no reason to
- 32:03Speaker 1: believe that that position is a legitimate one. And then
- 32:06Speaker 1: they will go through that confirmation by a cycle where
- 32:09Speaker 1: they look for every conceivable piece of information they can
- 32:12Speaker 1: to make them feel right about that position they arbitrarily
- 32:15Speaker 1: chose in the first place. It's just it's kind of incredible.
- 32:19Speaker 2: It's not like and it's slipped up before. This is
- 32:22Speaker 2: not stupid people. They can be very incredibly smart people.
- 32:26Speaker 2: And so he actually has a quote specific to that,
- 32:29Speaker 2: did you want to take that?
- 32:30Speaker 1: Oh, you can do it if you want.
- 32:31Speaker 2: He goes on to say, quote, an ignorant mind is
- 32:34Speaker 2: precisely not a spotless, empty vessel, but one that's filled
- 32:38Speaker 2: with the clutter of irrelevant or misleading life experiences, theories, facts, intuitions, strategies, algorithms, heuristics, metaphors,
- 32:45Speaker 2: and hunches that regrettably have the look and feel of
- 32:48Speaker 2: useful and accurate knowledge. So essentially, what he's saying, there's
- 32:52Speaker 2: all this information that sounds good, it feels right, and
- 32:56Speaker 2: they're not people that are dumb. They're taking that information,
- 32:58Speaker 2: they're synthesizing that information that they have in turning it
- 33:01Speaker 2: into an argument or a position that's not quite accurate.
- 33:06Speaker 1: And I mean that almost feels like politics in a
- 33:08Speaker 1: nutshell to me. Like this is this is where people
- 33:11Speaker 1: will get on major controversial topics. They will have a
- 33:15Speaker 1: lot of quote unquote information about that topic. And as
- 33:20Speaker 1: he said, it's not that they're stupid, and it's not
- 33:22Speaker 1: that their mind is empty, it's that it is filled
- 33:25Speaker 1: with the wrong stuff. And being filled with the wrong
- 33:28Speaker 1: stuff has the impression of being well informed, but it's
- 33:33Speaker 1: it's not well and it's informed in a way, but
- 33:35Speaker 1: it's not well informed. It's not meaningfully informed.
- 33:39Speaker 2: Accurately informed either, yes, exactly. Another thing that's part of
- 33:42Speaker 2: that is it becomes so well formed that it becomes
- 33:45Speaker 2: almost static. And that's part of the issue too, is
- 33:48Speaker 2: it's it's it's with new facts and new information, people
- 33:52Speaker 2: don't budge on their positions. So when they create these
- 33:54Speaker 2: ideas or or when they create this like body of knowledge,
- 33:58Speaker 2: it doesn't move. And that's that's part of the problem
- 34:01Speaker 2: with this too, is it's less about how people kind
- 34:04Speaker 2: of come into all this, but more about how when
- 34:06Speaker 2: they dig their heels in, they don't get out of it.
- 34:09Speaker 1: Yeah, I mean, so one way to summarize this, and
- 34:11Speaker 1: I'm not actually pulling this from the source material. I
- 34:14Speaker 1: made this up. But one thing that the theme that
- 34:16Speaker 1: really occurred to me as I was looking through this
- 34:17Speaker 1: research is to summarize this by saying that people don't
- 34:21Speaker 1: know what they don't know. When you don't have a
- 34:24Speaker 1: frame of reference for this, then you don't know that
- 34:26Speaker 1: you don't have a frame of reference for this, and
- 34:28Speaker 1: there is potentially a world's worth of knowledge of things
- 34:32Speaker 1: that you don't even know that you don't know. Like
- 34:35Speaker 1: an example of this, I have frequently heard people talk
- 34:39Speaker 1: about the field of study that I went into, and
- 34:42Speaker 1: someone even specifically said to me, how is there a
- 34:45Speaker 1: whole degree that you can get on that? How is
- 34:47Speaker 1: there more than like a class worth or even like
- 34:50Speaker 1: a day of a class worth of subject for that material?
- 34:53Speaker 1: And it's because they're so oblivious to the things that
- 34:56Speaker 1: to which they've had so little exposure and apparently believe
- 35:00Speaker 1: that their experiences have encompassed the vast majority of the
- 35:02Speaker 1: human experience. That one gap that they don't even know
- 35:07Speaker 1: that that is something that they don't know that they're missing.
- 35:10Speaker 1: And that's true for me as well. Like I don't
- 35:11Speaker 1: like I might look at it feels like there is
- 35:14Speaker 1: probably a whole field of people that just study like
- 35:18Speaker 1: paint texture. I'm just making that up. I don't etually
- 35:20Speaker 1: know if that's a thing, but like I would think, like,
- 35:23Speaker 1: how much is they're really to know about that? That
- 35:24Speaker 1: seems like such a simple topic and be completely wrong.
- 35:27Speaker 1: And again I don't know if that's actually a thing,
- 35:29Speaker 1: but there are going to be fields like that where
- 35:31Speaker 1: it seems to me that seems like something you could
- 35:33Speaker 1: learn from a five minute YouTube video, and actually there
- 35:36Speaker 1: are people who will spend years researching and studying and
- 35:38Speaker 1: learning everything there is to know about that subject, and
- 35:40Speaker 1: I wouldn't even know that that was something I was
- 35:42Speaker 1: missing when I started studying.
- 35:44Speaker 2: In my doctoral program, they basically said that you develop
- 35:47Speaker 2: this level of knowledge, that you get a very specific
- 35:50Speaker 2: understanding about a very specific topic to such a fine
- 35:53Speaker 2: point that you end up being the only person in
- 35:55Speaker 2: the world that really understands that topic to that depth.
- 35:58Speaker 2: I mean, you're talking about seven people and you're the
- 36:01Speaker 2: person that knows about that particular topic. Like when you
- 36:04Speaker 2: do your dissertation, you are the expert on that topic
- 36:07Speaker 2: at that point in time, and even then you're not
- 36:09Speaker 2: even really the expert. Yeah, and there's still plenty to
- 36:11Speaker 2: learn about that particular pinpoint of study.
- 36:14Speaker 1: Right.
- 36:15Speaker 2: So you thought you were listening to a podcast and
- 36:17Speaker 2: you were confident in that, But what you were not
- 36:19Speaker 2: confident is how many ads they were going to be. Surprise,
- 36:22Speaker 2: here's a new one, and we're back.
- 36:32Speaker 1: There is a little bit of hubris in here in
- 36:34Speaker 1: thinking that whoever it is, and it could be me
- 36:37Speaker 1: or you or anybody, where you sort of think, well,
- 36:40Speaker 1: I've learned enough about the world that I know all
- 36:42Speaker 1: the things, at least generally the categories of the things
- 36:45Speaker 1: that there are to know, and so part of the
- 36:47Speaker 1: point of this is really just to illuminate, like be
- 36:50Speaker 1: open and willing to acknowledge the fact that there might
- 36:52Speaker 1: be things out there that you don't know that you're missing.
- 36:54Speaker 2: Yeah, I mean, I think that's perfectly appropriate. So that's
- 36:57Speaker 2: kind of the thing about all this. It's not just
- 37:00Speaker 2: those stupid people who fall victims of this, Like we're
- 37:02Speaker 2: all pretty good at a small handful of things, right,
- 37:04Speaker 2: Like we all have our own experience. I think Bill
- 37:06Speaker 2: Nya says specifically, you can learn something new from every
- 37:09Speaker 2: person that you meet, Like I think that's one of
- 37:11Speaker 2: the best things I've ever heard, Like love that, And
- 37:12Speaker 2: it's really great because every person you meet is pretty
- 37:15Speaker 2: good at a small handful of things, and we are
- 37:18Speaker 2: good at calibrating ourselves with respect to those things, Like
- 37:20Speaker 2: we can kind of understand where we're at. But ultimately
- 37:22Speaker 2: what's going to happen is that we're not going to
- 37:25Speaker 2: be an expert in many other things, Like we're not
- 37:27Speaker 2: gonna I'm not Like, I play bass guitar, I've been
- 37:30Speaker 2: playing for almost twenty I've been playing for twenty years now.
- 37:33Speaker 2: I'm not anywhere near being an expert, and I've been
- 37:36Speaker 2: playing for most of my life not as good as Flee,
- 37:39Speaker 2: and I'm never going to be as good as Flea.
- 37:41Speaker 2: That's absurd to think like that is a stretch goal.
- 37:43Speaker 2: If you will love that, it's never going to contact that.
- 37:48Speaker 1: Yeah, yeah, you like that.
- 37:49Speaker 2: So every brilliant, incomprehensibly genius aeradite will lack some knowledge
- 37:55Speaker 2: about something and will fail to know what they don't
- 37:58Speaker 2: know about what ever subject they are not an expert in. Everybody,
- 38:03Speaker 2: all of us have this. We cannot possibly know all
- 38:06Speaker 2: of the things.
- 38:07Speaker 1: Yeah, this is a human thing. This is just And
- 38:10Speaker 1: the point of this again is to just be made
- 38:12Speaker 1: more aware of our biases that that are out there,
- 38:14Speaker 1: so that at the very least we can acknowledge that
- 38:18Speaker 1: we maybe don't know as much as we think, and
- 38:20Speaker 1: maybe be slightly more hesitant about making and really you know,
- 38:25Speaker 1: holding our ground on claims that we maybe are missing
- 38:27Speaker 1: information about and at least be open to new information
- 38:30Speaker 1: about that thing.
- 38:31Speaker 2: Absolutely. I like that. I like the way that sounds.
- 38:34Speaker 2: That's nice.
- 38:34Speaker 1: Thanks, all right, So let's go ahead and get into
- 38:37Speaker 1: how this works and why it works and that sort
- 38:39Speaker 1: of thing. I mean, we sort of already did elaborate
- 38:41Speaker 1: in this a bit, but I think we can really
- 38:43Speaker 1: elaborate on this in just a different way that might
- 38:45Speaker 1: make it easy to understand, or at least just approach
- 38:48Speaker 1: in a way that helps sort of cement it in place.
- 38:50Speaker 1: And this is essentially as simple as a logic comparison task,
- 38:53Speaker 1: or that's that's the way you can sort of frame it.
- 38:55Speaker 1: And so let me let me say a little bit
- 38:57Speaker 1: more about that. Most animals with the ability to sense things,
- 39:00Speaker 1: especially visually, can tell the difference between concrete comparisons, such as,
- 39:04Speaker 1: this thing is bigger than this thing right right now.
- 39:07Speaker 1: There's a smaller number of animals in the world that
- 39:09Speaker 1: can tell the difference between semantic and arbitrary comparisons, such as,
- 39:13Speaker 1: this thing is more valuable than this thing.
- 39:15Speaker 2: Okay, that's why we put fancy rocks and jewelry exactly.
- 39:18Speaker 1: That's exactly it. That is why we hold these little
- 39:23Speaker 1: rocks and we will pay exorbitant amounts of money for them.
- 39:27Speaker 1: Is because we can look at that and someone said,
- 39:29Speaker 1: this is worth a lot more than all the other rocks,
- 39:31Speaker 1: and we will go, okay, here is all my money,
- 39:35Speaker 1: and then and yeah, so that's anyway excessively political stance
- 39:40Speaker 1: on jewelry. The Dunning Kruger effect is the extent to
- 39:45Speaker 1: which we make comparisons to thing that we don't even
- 39:48Speaker 1: know exist, and we tend to underestimate how vast those
- 39:51Speaker 1: things are, or at least they might be. And so
- 39:53Speaker 1: ancient people likely believe that the moon was fairly small
- 39:57Speaker 1: and just maybe a few hundred or a few thousand
- 40:00Speaker 1: miles off the ground because they really lacked any context
- 40:03Speaker 1: or reason to believe that it was otherwise right, And
- 40:06Speaker 1: so this is just the ability to arbitrarily compare what
- 40:09Speaker 1: they knew to what they were seeing. They just didn't
- 40:12Speaker 1: have the information. Just for clarification, the moon is two
- 40:15Speaker 1: hundred and thirty thousand miles away. Yeah, shit varies, but
- 40:18Speaker 1: it's around that. So it's quite a bit more than
- 40:21Speaker 1: you might guess if it's like, wow, that moon must
- 40:23Speaker 1: be one hundred miles away a little bit more. Yeah,
- 40:27Speaker 1: it's a few more.
- 40:28Speaker 2: I mean. And just to kind of like further elaborate
- 40:30Speaker 2: on that too, like you're talking about like astral bodies
- 40:33Speaker 2: and all that, But I mean, how much is there
- 40:35Speaker 2: to know about rabbit poop? Like I literally don't know.
- 40:38Speaker 2: I have no idea, but there's a whole study. I mean,
- 40:41Speaker 2: there are people that treat copper phasia, like there are
- 40:44Speaker 2: people that there's just they're experts in poop, and they're
- 40:46Speaker 2: experts in specific types of poop.
- 40:49Speaker 1: Yeah, there's probably a lot more to know about this
- 40:51Speaker 1: than immediately seems to make sense.
- 40:53Speaker 2: Right, Absolutely, it's just to kind of like press the
- 40:56Speaker 2: issue a little bit more, Like how much is there
- 40:58Speaker 2: to know about installing plumbing? I mean the entire professions
- 41:01Speaker 2: dedicated to this particular trade, right, And you know, there's
- 41:06Speaker 2: so much to know when you're looking at any sort
- 41:09Speaker 2: of plumbing, and there maybe we know a few tasks
- 41:11Speaker 2: like how to unclog a drain or how to you know,
- 41:15Speaker 2: maybe dial a phone so that somebody else can come
- 41:17Speaker 2: unclog the drain. I'm not very handy myself, Yeah, saying
- 41:20Speaker 2: there's just a lot of stuff that goes into something
- 41:23Speaker 2: as particular as a particular skill set or particular trade,
- 41:26Speaker 2: and that within itself continually evolves, right, So to me,
- 41:32Speaker 2: plumbers are just these really cool magicians.
- 41:34Speaker 1: Yeah. Yeah. Basically I've tried to take on some home
- 41:37Speaker 1: projects myself and thought that like, well, well, how much
- 41:39Speaker 1: how difficult can it be to install this sink or whatever?
- 41:42Speaker 1: And turns out it's enormously difficult and something that I
- 41:46Speaker 1: would rather never do again if possible, And so yeah,
- 41:49Speaker 1: it makes me wonder. I'm like, man, is someone whose
- 41:51Speaker 1: job it is to do this? How how do you
- 41:53Speaker 1: get so? Like this thing just seems basically impossible at
- 41:56Speaker 1: first glance to me. And again that's just me highlighting
- 42:01Speaker 1: how little I know about that field.
- 42:03Speaker 2: Yeah, when I was in high school, I took an
- 42:04Speaker 2: electronics class and learned how to like rewire a wall.
- 42:08Speaker 2: But then I had to like install an outlet somewhere
- 42:11Speaker 2: in my house not too long ago, and I was like,
- 42:13Speaker 2: I was so parent on its Like I had to
- 42:15Speaker 2: go get like a rubber handled screwdriver and turn off
- 42:18Speaker 2: all the fuses in the house just to install one thing.
- 42:20Speaker 2: I was like, this is ridiculous, Like I literally don't
- 42:22Speaker 2: know enough to be safe. I'm gonna end up like
- 42:24Speaker 2: electricating myself.
- 42:25Speaker 1: I think this is actually a important point there is
- 42:27Speaker 1: don't know enough to be safe. That's something we should
- 42:29Speaker 1: maybe come back to.
- 42:30Speaker 2: Yeah, no, for sure, so we don't know enough to
- 42:32Speaker 2: be safe, So don't just just be aware, just just
- 42:35Speaker 2: be just be aware of what you try to be
- 42:37Speaker 2: aware of what you don't know.
- 42:38Speaker 1: Just don't just don't, just don't ask ask for help. Yeah. So, yeah,
- 42:42Speaker 1: the more things you learn, the more you're exposed to,
- 42:44Speaker 1: the better you're able you will be to understand the
- 42:46Speaker 1: limits of your own knowledge and in your competence in something.
- 42:50Speaker 2: Yeah.
- 42:51Speaker 1: Absolutely, So there's always a few interesting tidbits and considerations
- 42:54Speaker 1: that are fun to pepper into a discussion like this.
- 42:57Speaker 1: So one thing is that the Dunning Kruger effect could
- 42:59Speaker 1: be described as a form of the over confidence effect.
- 43:03Speaker 1: In fact, I actually had a difficult time telling exactly
- 43:05Speaker 1: how these things were different, except it does seem that
- 43:08Speaker 1: the Dunning Kruger effect identify the aspect of the correlation
- 43:11Speaker 1: that confidence is reciprocally related to competence, whereas the over
- 43:16Speaker 1: confidence effect really only seems to describe the tendency to
- 43:19Speaker 1: overestimate one's ability. And that was the example I gave
- 43:22Speaker 1: of ninety percent of people think they're better drivers than
- 43:24Speaker 1: fifty or ninety percent of other people. And it's true
- 43:26Speaker 1: of a lot of other things as well. And actually
- 43:28Speaker 1: that had me evaluate my own driving, and I decided
- 43:31Speaker 1: I must be perfectly average I think maybe I might
- 43:33Speaker 1: actually be a little bit less an average, And I'm
- 43:35Speaker 1: thinking about like stunt drivers and people who are professional
- 43:38Speaker 1: drivers are probably really really good at it. And I
- 43:41Speaker 1: am perfectly capable of navigating a car without getting in
- 43:44Speaker 1: an accident most of the time. But I would guess
- 43:46Speaker 1: that probably the best place to put myself is right
- 43:49Speaker 1: smacked down in the middle, if I really were to
- 43:50Speaker 1: think about it carefully. And I think that there is
- 43:54Speaker 1: This again wasn't explicitly stated in the Dunning Kruger effect,
- 43:57Speaker 1: but this does seem to also be related to the
- 43:58Speaker 1: idea that you mentioned earlier of the imposter effect, which
- 44:01Speaker 1: is the idea that when you are become more and
- 44:04Speaker 1: more and more of an expert in something, sometimes you
- 44:06Speaker 1: find yourself feeling like you are kind of a fraud
- 44:09Speaker 1: or you don't really know that much about what you're doing.
- 44:12Speaker 1: And this is a thing that happens with people who
- 44:14Speaker 1: are in who achieve a high degree of speciality in
- 44:18Speaker 1: a particular subject, they will actually feel a lack of
- 44:21Speaker 1: confidence and their competence in that subject because they know
- 44:24Speaker 1: how much they don't know.
- 44:26Speaker 2: Absolutely that makes sense.
- 44:27Speaker 1: So another thing in here is just this is a
- 44:30Speaker 1: way to think about the Stunning Kruger effect and maybe
- 44:33Speaker 1: think about yourself and just have some consideration around this.
- 44:36Speaker 1: And the suggestion here is to think of something you're
- 44:38Speaker 1: an expert in, and how much the average person knows
- 44:41Speaker 1: about your area of expertise, and how little even that
- 44:44Speaker 1: they don't know about your primary subject. And then that
- 44:48Speaker 1: is you about everything you're not an expert in. Yeah, okay,
- 44:52Speaker 1: so that's the thought experiment I'm proposing. And I got
- 44:55Speaker 1: this specifically from a book that I'm putting in the
- 44:56Speaker 1: show notes called The Skeptics Guide to the Universe book,
- 44:59Speaker 1: where they give this as an example as a way
- 45:02Speaker 1: specifically to address the Dunning Cougar effect. If you think
- 45:05Speaker 1: about how little people know about the thing that you
- 45:07Speaker 1: are really good at, now apply that to yourself with
- 45:10Speaker 1: respect to everything you're not an expert in, which is
- 45:13Speaker 1: gonna be most things, right. I am not an expert
- 45:16Speaker 1: in the climate. I am not expert in the oceans.
- 45:18Speaker 1: I am not an expert in animals. I am not
- 45:19Speaker 1: an expert in plants. I'm not an expert in like computers.
- 45:23Speaker 1: I'm not expert in movies or literature or any of
- 45:26Speaker 1: those things. I'm an expert in my field and maybe
- 45:29Speaker 1: a little bit in board games and like, so those
- 45:31Speaker 1: things are are things that I am. I am very
- 45:35Speaker 1: very very narrow on and I feel really confident about
- 45:37Speaker 1: those things. But I am utterly average or less than
- 45:43Speaker 1: average or at least moderately incompetent about everything else in
- 45:47Speaker 1: the world about which there are experts.
- 45:49Speaker 2: And to kind of further get into that, like like
- 45:52Speaker 2: you mentioned like being an expert in your field, Like
- 45:54Speaker 2: if I walk into a room full of people that
- 45:57Speaker 2: have no experience in my field, then technically I'm the
- 45:59Speaker 2: ex in my field that's currently present. But there are
- 46:03Speaker 2: things in my field that I have never contacted or
- 46:06Speaker 2: things that blow my mind. Like I'll pick up a
- 46:09Speaker 2: book of something that's in my field and I'm like,
- 46:11Speaker 2: what the hell does this even mean?
- 46:13Speaker 1: Yeah, right, yeah, I've seen those.
- 46:15Speaker 2: So I think that's an important thing too, is like
- 46:17Speaker 2: you might be an expert to some degree, and then
- 46:20Speaker 2: there's some things that you like you can always kind
- 46:22Speaker 2: of know more about what you know.
- 46:24Speaker 1: Yeah, I mean absolutely. Just one of the really quick
- 46:28Speaker 1: thing is that this idea of the Dunning Kruger effect
- 46:31Speaker 1: is also related to the notion of something called illusory superiority,
- 46:35Speaker 1: which is a very similar sort of idea, the illusion
- 46:38Speaker 1: that you are better at something than you are, or
- 46:40Speaker 1: you're the best at something and you're not really the
- 46:43Speaker 1: best at something. That's just a general thing. But that's
- 46:46Speaker 1: all I had on this. Do you good to move
- 46:48Speaker 1: on to our ticcoms? Yeah?
- 46:49Speaker 2: I am good to move on. I think you really
- 46:51Speaker 2: nailed it.
- 46:52Speaker 1: Thanks. I think the very first take on point really
- 46:55Speaker 1: should be that there is a massive amount of information
- 46:58Speaker 1: that I don't know about this topic, and I mean
- 47:02Speaker 1: really digging into this. There have been an avalanche of
- 47:06Speaker 1: studies that have followed this that have explored the ins
- 47:09Speaker 1: and outs and the depths of this thing that continue
- 47:11Speaker 1: to be researched because there is so much to know
- 47:14Speaker 1: about this topic.
- 47:16Speaker 2: Yeah. I think another one is if you hear about
- 47:18Speaker 2: something new that you didn't have any idea existed at all,
- 47:22Speaker 2: assume that there is probably a lot more to that
- 47:24Speaker 2: thing than you might think at first glance. So there's
- 47:27Speaker 2: it's probably like the tip of the iceberg phenomenon, right
- 47:29Speaker 2: like where like you kind of come into contact with
- 47:31Speaker 2: a little bit of it, but there's so much more
- 47:33Speaker 2: to understand about that within our own universe.
- 47:36Speaker 1: Yeap. And this is where I get to go a
- 47:38Speaker 1: little bit. I'm on a soapbox here thing, and I
- 47:40Speaker 1: want to just make sure that there's a caveat. One
- 47:42Speaker 1: thing that occurred to me as we were talking about
- 47:44Speaker 1: this is I could certainly see people who have that
- 47:47Speaker 1: confirmation bias who actually use the discussion we have here
- 47:51Speaker 1: as evidence to support their confirmation bias about something for
- 47:55Speaker 1: which they are wrong. And so an important caveat here
- 47:58Speaker 1: is that just because you might not know what you
- 48:01Speaker 1: don't know, and you might not know everything about a
- 48:03Speaker 1: particular area, does not mean that all ideas that someone
- 48:07Speaker 1: proposed are equally valid and therefore should be given equal
- 48:10Speaker 1: weight and consideration or deserve an equal amount of attention
- 48:13Speaker 1: and resources to understand. Okay, And furthermore, there are people
- 48:17Speaker 1: who will gleefully disseminate completely incorrect information, knowing it's incorrect,
- 48:22Speaker 1: that makes it appear as though their argument is supported
- 48:25Speaker 1: even though they just made up that information. So like,
- 48:29Speaker 1: here are some very basic things. Homeopathy is not medicine.
- 48:32Speaker 1: The Earth is round, It was not created five to
- 48:36Speaker 1: seven thousand years ago. The Earth is not hollow. Humans
- 48:39Speaker 1: have landed on the moon, drinking boiling water is fatal.
- 48:42Speaker 1: Keelation can kill you if you don't need it. Vaccines
- 48:44Speaker 1: do not cause autism or other neurological diseases. There are
- 48:47Speaker 1: not human spirits floating around as ghosts. The good place
- 48:51Speaker 1: is or was at the time of wherever you hear
- 48:53Speaker 1: this an amazing TV show. There is no such thing
- 48:55Speaker 1: as Bigfoot or the Lockness Monster, and the pyramids in
- 48:58Speaker 1: the Easter Island were not built by aliens. These are
- 49:00Speaker 1: just things, and just because I say that, and I'm
- 49:03Speaker 1: not an expert in those things, does not mean that
- 49:05Speaker 1: the alternative hypothesis is actually a tenable, reasonable place to be.
- 49:10Speaker 1: It often does not make any conceptual sense, and there
- 49:12Speaker 1: is often little or no evidence behind it. Okay, it's
- 49:16Speaker 1: just I want to make sure that we really do
- 49:18Speaker 1: point out that just because I say I might not
- 49:20Speaker 1: be an expert in homeopathy, therefore that is equally valid
- 49:23Speaker 1: as a consideration of medicine. Is knowing as much as
- 49:26Speaker 1: I do about it, which again isn't everything is enough
- 49:29Speaker 1: to know that there's nothing there.
- 49:30Speaker 2: I like firey Abraham, Oh good, sorry you spit hot fire.
- 49:35Speaker 2: It's good I did.
- 49:36Speaker 1: Yeah, my microphone melted.
- 49:38Speaker 2: Yeah. Yeah. Also, I fully support everything you just said,
- 49:41Speaker 2: so I guess is yeah, I endorsed that. So if
- 49:45Speaker 2: we were, if we were politicians and running partners, I
- 49:47Speaker 2: would I would absolutely be like, yeah, well he said so.
- 49:51Speaker 2: Another thing too, to kind of take away from this
- 49:53Speaker 2: is like display a little bit of humility. Just displaying
- 49:56Speaker 2: humility to look like you're avoiding this effect does not
- 49:58Speaker 2: mean your opinion is justified. So again like going back
- 50:01Speaker 2: and saying like, well, I don't know, but maybe vaccines
- 50:05Speaker 2: cause all the autism, Like if you're kind of going
- 50:08Speaker 2: from that route of like I don't know at all,
- 50:10Speaker 2: but this is kind of what it is. It doesn't
- 50:11Speaker 2: really give your opinion any sort of It doesn't hold
- 50:14Speaker 2: any water, Like, it doesn't. Just because you're being modest
- 50:17Speaker 2: about a situation or our particular subject doesn't mean that
- 50:19Speaker 2: your opinion is still valid about it. There still needs
- 50:21Speaker 2: to be some evidence and support for what you're saying.
- 50:24Speaker 1: Right, I mean, the point is that armed with the
- 50:27Speaker 1: information that you might be overestimating your ability or knowledge
- 50:30Speaker 1: about something, consider questioning how well you really know that thing,
- 50:34Speaker 1: and try and find conflicting data and learned how and
- 50:37Speaker 1: where you might be wrong. Like that's essentially the scientific
- 50:40Speaker 1: process is to find where do things not work, where
- 50:43Speaker 1: do they break down, where is information incorrect, what are
- 50:46Speaker 1: considerations that haven't actually been included in the research so far,
- 50:50Speaker 1: and figure out how to better understand the world by
- 50:52Speaker 1: breaking down the assumptions that we have coming into it.
- 50:55Speaker 2: Yeah. So, I guess one of the big take holmes
- 50:58Speaker 2: is if by the end of this episode you're fine
- 51:00Speaker 2: yourself questioning what you believe or what you know, that,
- 51:02Speaker 2: I think that we've done a pretty good job.
- 51:04Speaker 1: Yeah. As a general rule, I'd recommend that you assume
- 51:06Speaker 1: that anything you don't know about or you aren't an
- 51:09Speaker 1: expert in that there is something for you to learn
- 51:12Speaker 1: about that subject, and also keeping in mind that caveat
- 51:16Speaker 1: that like it should fit within the parameters of general
- 51:18Speaker 1: understanding about how the universe works. Agreed, all right, I
- 51:21Speaker 1: have a couple of really cool quote quotes to close
- 51:24Speaker 1: this out, if you don't mind, Yeah, let's do it. So.
- 51:26Speaker 1: The first one is quote the greatest enemy of knowledge
- 51:28Speaker 1: is not ignorance, it's the illusion of knowledge. End quote.
- 51:31Speaker 1: And I don't I don't know the source of them,
- 51:33Speaker 1: and I think the source is unknown. I'm not sure.
- 51:34Speaker 2: Yeah. Another one would be the problem with the world
- 51:38Speaker 2: is that the intelligent people are full of doubt while
- 51:40Speaker 2: the stupid are full of confidence. And that's either by
- 51:42Speaker 2: Charles Pakowski or Bert try and Russell. It's hard to
- 51:44Speaker 2: find and pinned down which one said that.
- 51:46Speaker 1: I saw both from various sources, and yeah, I don't know.
- 51:51Speaker 1: It was interesting. And then the last one is quote
- 51:53Speaker 1: ignorance more frequently begets confidence than does knowledge. End quote.
- 51:57Speaker 1: And that was by Charles Darwin. Thank you, Charles Darwin,
- 52:00Speaker 1: the well known Charles Darwin, you might say, famously studied
- 52:05Speaker 1: Charles Darwin. Yeah, I feel good about that.
- 52:08Speaker 2: Also, hopefully, so now I know I don't know what
- 52:11Speaker 2: I don't know, and now I'm afraid that what I
- 52:13Speaker 2: know is not enough.
- 52:15Speaker 1: Great, Well, hopefully I didn't leave you in any sort
- 52:18Speaker 1: of existential crisis. But go out and learn about the world,
- 52:20Speaker 1: you know. That's I mean, that'd be my command to
- 52:22Speaker 1: do myself and you and everyone else.
- 52:23Speaker 2: Yeah, I agree with that. I like that. That's a
- 52:25Speaker 2: good charge.
- 52:26Speaker 1: Let's once again disrupt this disseminating and hopefully smart thing
- 52:31Speaker 1: that we're doing to bring you something different than that. Ads,
- 52:42Speaker 1: all right, we are back, all right. So that was
- 52:50Speaker 1: our discussion about the Dunny Krueger effect, where we sort
- 52:53Speaker 1: of covered the history of this, how it works, different
- 52:56Speaker 1: things to understand about it. We sort of unpacked the
- 52:59Speaker 1: original experience mint and all of that. So there has
- 53:03Speaker 1: continued to be a decent amount of research on this
- 53:06Speaker 1: topic in the sort of psychological sphere, and there have
- 53:10Speaker 1: been some people who have been, I think, pushing a
- 53:14Speaker 1: somewhat more skeptical view of how robust of an effect
- 53:19Speaker 1: this is. Now a lot of people have replicated this
- 53:22Speaker 1: in some version or another, so I think it's reasonable
- 53:24Speaker 1: to accept that there is something about this that's there
- 53:27Speaker 1: because it has been replicated so many times. But there
- 53:30Speaker 1: are also some people who have been pushing back a
- 53:33Speaker 1: little bit, saying, maybe it's not exactly what we think
- 53:36Speaker 1: it is. But let's start with one study that we
- 53:38Speaker 1: found that sort of unpacked a different aspect of the
- 53:42Speaker 1: Dunning Cougar effect.
- 53:43Speaker 2: Yeah. So, one potential reason that people are bad at
- 53:46Speaker 2: estimating their performance is that they don't get any feedback
- 53:49Speaker 2: or information about themselves. So in a twenty thirteen study,
- 53:53Speaker 2: they asked one hundred and sixty five bridge players, which
- 53:57Speaker 2: you know, apparently people play bridge. Still the one hundred
- 54:00Speaker 2: and sixty five bridge players to estimate their performance in
- 54:03Speaker 2: several games and even received feedback on their performance. And
- 54:06Speaker 2: despite having explicit knowledge about their performance, the bottom one
- 54:10Speaker 2: third of people still overestimated their performance, and HIGs performing
- 54:14Speaker 2: people still underestimated their performance.
- 54:17Speaker 1: So essentially, what they were suggesting was, even when you
- 54:20Speaker 1: know that you're not accurately estimating your own ability, you
- 54:24Speaker 1: will still incorrectly estimate your ability, right yeah, which was
- 54:30Speaker 1: a definitely a different take on this from assuming that, like,
- 54:33Speaker 1: the reason that they don't know that they're as bad
- 54:36Speaker 1: at this as they are is because they don't get
- 54:37Speaker 1: any feedback on it. And like, no, even when they
- 54:38Speaker 1: get feedback, they still think they're better than they are
- 54:41Speaker 1: or worse than they are. For again, the lower performers
- 54:44Speaker 1: tend to think they're better, the higher performances tend to
- 54:46Speaker 1: think that they're worse or underestimate their performance, if you will.
- 54:49Speaker 1: Right now, that does kind of lead to an updated
- 54:53Speaker 1: article that I found. I don't believe this was a
- 54:56Speaker 1: peer reviewed article. I believe this was just published online. Nevertheless,
- 54:59Speaker 1: they made it interesting points, and this was published in
- 55:01Speaker 1: twenty twenty three in Scientific American. And this expresses some
- 55:06Speaker 1: skepticism about the sort of strength and robustness of the
- 55:10Speaker 1: Dunning Kruger effect, as they had mentioned before. And really
- 55:14Speaker 1: one of the arguments is that the data collection methods
- 55:17Speaker 1: in the experiments, the original one and maybe subsequent ones,
- 55:20Speaker 1: and the experimental arrangement will inevitably lead to the conclusion
- 55:25Speaker 1: that they got in the Dunning Kruger effect. But that's
- 55:29Speaker 1: just because that's how math sort of works. And here's
- 55:31Speaker 1: what I mean. One of the assumed premises that they
- 55:35Speaker 1: went into with this discussion that they had here and
- 55:38Speaker 1: I think has been well demonstrated elsewhere, is that most
- 55:41Speaker 1: people tend toward the average, and more importantly, most people
- 55:45Speaker 1: tend to rank themselves higher than their peers on everything.
- 55:49Speaker 1: One of the most often cited studies on this showed
- 55:52Speaker 1: that ninety three percent of drivers in America think that
- 55:56Speaker 1: they are better than average. Three percent is almost all
- 56:01Speaker 1: of them. So I know we've joked about on her
- 56:04Speaker 1: like the fact I qualify this is always a joke,
- 56:06Speaker 1: but like ninety three percent. Now, presumably that does include
- 56:11Speaker 1: some of the really good drivers and some really poor drivers,
- 56:14Speaker 1: but ninety three percent of drivers in America think they
- 56:17Speaker 1: are better than average, which is mathematically impossible, right, Like,
- 56:21Speaker 1: most people will be around average and some people will
- 56:23Speaker 1: be on the extremes, but most people believe that they're
- 56:26Speaker 1: above average. But that's a really important initial starting point
- 56:30Speaker 1: for the conclusions that they reached in this article. Yeah.
- 56:33Speaker 2: Absolutely, they created and fifty four fake students, so the
- 56:38Speaker 2: range of scores from low to high, then assigned random
- 56:41Speaker 2: numbers as confidence ratings, simply arranging the students on a
- 56:45Speaker 2: graph and then arranging the randomly assigned confident scores. The
- 56:48Speaker 2: bottom performance would have confidence scores higher than the average
- 56:52Speaker 2: by a similar range and as the original study, while
- 56:54Speaker 2: the top performers have confidence scores lower than the average
- 56:58Speaker 2: by a similar range. Is the original study. The fact
- 57:00Speaker 2: that the estimated scores were higher was just an artifact
- 57:05Speaker 2: of the math. That their scores were lower, so most
- 57:08Speaker 2: numbers would be higher, and the same is true for
- 57:11Speaker 2: the top performers. So remember all that's fake, but the
- 57:15Speaker 2: math just worked out as it was.
- 57:17Speaker 1: Yes, So basically just if they took I actually think
- 57:21Speaker 1: they did sort of a linear progression of like we're
- 57:23Speaker 1: just going to make up those over a thousand fake students.
- 57:25Speaker 1: We're just going to make up scores from them that
- 57:27Speaker 1: mostly go from the low end to the high end.
- 57:29Speaker 1: And then we're going to plot them, so we group
- 57:31Speaker 1: the lowest quartile of performers than the mid low, mid high,
- 57:35Speaker 1: and the highest quartile of performers, and then we're just
- 57:38Speaker 1: going to show where the confidence intervals fall. But again,
- 57:41Speaker 1: those confidence rankings were totally random, literally completely and totally random, right,
- 57:46Speaker 1: But it just so happens to be that most numbers
- 57:48Speaker 1: are lower than the or were higher than the lowest numbers,
- 57:51Speaker 1: and most numbers are lower than the highest numbers. And
- 57:53Speaker 1: so that meant that even if you sort of spread
- 57:56Speaker 1: out the distribution of confidence scores, well, that would be
- 57:59Speaker 1: all over the place. It would look like the people
- 58:02Speaker 1: on the low end were overestimating themselves just because they
- 58:04Speaker 1: tended toward the middle, and the same thing is true
- 58:06Speaker 1: for the highest performance. It looked like they underestimated themselves
- 58:10Speaker 1: just because they tended toward the middle, right, And so
- 58:12Speaker 1: they were sort of saying, it's just it's just kind
- 58:14Speaker 1: of how math works that that would be the case
- 58:16Speaker 1: that maybe their own self evaluation isn't like that off
- 58:21Speaker 1: of where they really are.
- 58:23Speaker 2: Right absolutely now, in a non experimental arrangement. A professor
- 58:27Speaker 2: gave a scientific literacy test to some students. Only sixteen
- 58:31Speaker 2: percent of the lowest performers overestimated their performance, while four
- 58:35Speaker 2: percent actually underestimated their performance. About eight percent of the
- 58:39Speaker 2: lower performers were pretty good at estimating how well they did.
- 58:42Speaker 2: So that's I mean, it's not experimental, but it still
- 58:46Speaker 2: tells you a little bit about kind of like what
- 58:47Speaker 2: the actual like kind of what's happening in a real
- 58:50Speaker 2: world scenario.
- 58:52Speaker 1: Yeah, exactly. So, while like most of the people who
- 58:55Speaker 1: performed low actually did get pretty close on estimating how
- 58:59Speaker 1: they did, some were significantly over, some were significant, but
- 59:02Speaker 1: importantly some were significantly under. Like the lowest performers actually
- 59:06Speaker 1: thought they did worse than they really did. Also happened,
- 59:09Speaker 1: But most of them were kind of close to their
- 59:12Speaker 1: actual their actual performance. And essentially what they're arguing then
- 59:16Speaker 1: is like maybe they were they were actually fairly good.
- 59:19Speaker 1: But again we have those law of averages here that
- 59:21Speaker 1: it tends to that they're just skew toward the middle. Essentially,
- 59:25Speaker 1: the case I think that they're making is that maybe
- 59:28Speaker 1: the most robust interpretation of the evidence that we have
- 59:32Speaker 1: as far as it relates to the Dunning Kruger effect
- 59:34Speaker 1: is that most people think that they're better than average.
- 59:37Speaker 1: Maybe that's sort of the conclusion we can draw from
- 59:39Speaker 1: this sure, Or maybe they're sort of close ish to
- 59:41Speaker 1: average but mostly better than average. Perhaps we're too confident
- 59:46Speaker 1: in the linear relation of unintelligent but confident to intelligent
- 59:49Speaker 1: but unconfident, or maybe we're under we were under confident
- 59:53Speaker 1: in how much we actually know.
- 59:55Speaker 2: Oh, look at that, our heads fully exploded because a,
- 1:00:00Speaker 2: you know, it's funny thinking that, like the original idea
- 1:00:03Speaker 2: dunning Kruger effect may have overestimated the effect of the
- 1:00:07Speaker 2: dunning Kruger effect.
- 1:00:09Speaker 1: That would be And then there's a there's a very
- 1:00:11Speaker 1: common graph that that people use when they're talking about
- 1:00:14Speaker 1: the Dunning Kruger effect that wasn't actually in the Dunning
- 1:00:16Speaker 1: Kruger effect. And what it is is there's like a
- 1:00:20Speaker 1: confident scale and a percent correct and that like peaks
- 1:00:23Speaker 1: really high where they're like really confident, but their percentage
- 1:00:26Speaker 1: is really low, and then it drops off as you
- 1:00:28Speaker 1: learn more and more, but you get less and less confident, right,
- 1:00:31Speaker 1: and then it peaks back up again as you get
- 1:00:33Speaker 1: more com or as you learn more, and then you
- 1:00:35Speaker 1: become more confident, but you never get quite as high
- 1:00:38Speaker 1: as that, how confident you were to begin with when
- 1:00:40Speaker 1: you knew nothing, And they call that mount stupid on
- 1:00:42Speaker 1: the graph, Yes, but like we don't know where the
- 1:00:46Speaker 1: graph actually came from, Like it's not from the original
- 1:00:48Speaker 1: Dunning Krueger article. We can't find the original source. So
- 1:00:52Speaker 1: like even that is seems to be like kind of
- 1:00:54Speaker 1: ironic that people use that to represent the Dunning Kruger
- 1:00:58Speaker 1: effect with the like over confident that representation with us
- 1:01:01Speaker 1: not even from the actual study, Right, you're right, so wild,
- 1:01:05Speaker 1: I love it. Anyway, we should probably wrap that up here.
- 1:01:08Speaker 1: Thank you so much for listening and for joining us here.
- 1:01:10Speaker 1: We appreciate you all being around and joining us on
- 1:01:13Speaker 1: these trips down memory lane that we like to take.
- 1:01:16Speaker 1: And so I'd just like to thank my group of
- 1:01:19Speaker 1: people who helped make this happen. Thank you to my team.
- 1:01:22Speaker 1: Shane and myself do writing and fact checking. Our social
- 1:01:25Speaker 1: media coordinator is Emma Wilson, and the person who stitches
- 1:01:28Speaker 1: together all these old episodes that the new content is justin,
- 1:01:32Speaker 1: our audio producer Extraordinaiy. We do have some things to recommend,
- 1:01:37Speaker 1: which we do every episode but we did not do that.
- 1:01:41Speaker 1: I believe at the time that we recorded the original
- 1:01:43Speaker 1: Dunning Krugar episode. So we'll do that now. But first,
- 1:01:47Speaker 1: as I mentioned, if you like to support us over
- 1:01:49Speaker 1: on Patreon, you can get access to some behind the
- 1:01:50Speaker 1: scenes content, bonus content, AD free content, all that sort
- 1:01:54Speaker 1: of thing, and I will read your name as part
- 1:01:57Speaker 1: of the credits for helping make this little project of
- 1:01:59Speaker 1: ours continue to happen. So a big shout out and
- 1:02:02Speaker 1: thank you to Mike, m Megan, Mike t, Justin, Kim, Joshua, Brad, Stephanie, Olivia, Brian, Ashley, Kiara,
- 1:02:09Speaker 1: and Michelle for your ongoing and continued support. You are
- 1:02:12Speaker 1: the bestest, so great we are.
- 1:02:14Speaker 2: We just adore you.
- 1:02:16Speaker 1: Thanks to everyone who is listening today. Thank you for
- 1:02:18Speaker 1: recording with me today. Shane, is there anything that you'd
- 1:02:21Speaker 1: like to add or anything that I forgot before we
- 1:02:23Speaker 1: get to some recommendations?
- 1:02:24Speaker 2: Nope, I think we're I feel good.
- 1:02:33Speaker 1: Recommendations because I don't remember how long the original episode
- 1:02:37Speaker 1: was and I don't want to make this go too long.
- 1:02:38Speaker 1: I'm gonna be quick. I'm recommending a recent animated movie,
- 1:02:41Speaker 1: this is Despicable Me for the fourth installment and the
- 1:02:44Speaker 1: Despicable Me franchise, and it is a Despicable Me movie.
- 1:02:48Speaker 1: It is everything you want from a Despicable movie and
- 1:02:51Speaker 1: better than a Ninny Minion's movie. It's cute, it's funny,
- 1:02:54Speaker 1: it's silly, it's ridiculous. It has the animation has gotten
- 1:02:58Speaker 1: very very good, so you're if you're in for a fun,
- 1:03:03Speaker 1: silly child's sort of movie, just Despicable Bee for is
- 1:03:07Speaker 1: quite good. So if you're interested, good check it out.
- 1:03:09Speaker 2: That sounds like a lot of fun. I've been wanting
- 1:03:11Speaker 2: to see it and I have not seen it yet.
- 1:03:12Speaker 2: So I'm gonna recommend a blog, a food blog, and
- 1:03:16Speaker 2: it is called The Conscious Plant Kitchen. The reason I
- 1:03:20Speaker 2: am recommending this is because it is just a ton
- 1:03:23Speaker 2: of free recipes when you go on the website, like
- 1:03:27Speaker 2: right now, I'm looking at a recipe for pumpkin energy balls,
- 1:03:31Speaker 2: but they have just a ton of recipes on the website.
- 1:03:33Speaker 2: If you are looking to do a vegan diet or
- 1:03:37Speaker 2: certain types of diet like egg free, vegan, dairy free, vegetarian,
- 1:03:40Speaker 2: gluten free, nut free, grain free, there's lots of different
- 1:03:43Speaker 2: kind of It's a lot of baking, so a lot
