- 0:03You're listening to Why we Do what we Do. Welcome to Why we Do
- 0:16what we Do Mini. I'm your host Abraham and I'm Shane. This is
- 0:19our short form series where we just do a quick deep dive, a deep
- 0:23sort of shallowish, I don't know. We do a dive on a topic,
- 0:25and so we'll jump right in. Let's talk about science, Shane.
- 0:28I love science. It's one of my favorite things in the world. Yes,
- 0:31it's very good science, very cool science. Good. Now we're going
- 0:35to talk about these there's sort of a way of describing events in the world
- 0:40that has arranged into statements about those observations. And these scientific statements then have
- 0:46are sort of well regarded by people. And now just go through them really
- 0:49quickly. I think the science often, usually, or pretty much always proceeds
- 0:53through a series of language based steps to understand some observed pattern. We've got
- 1:00an observation, a hypothesis, a law, and a theory, and so
- 1:03let's break down what those things are. Yes, so when we talk about
- 1:07an observation, we're talking about seeing something right. That's really what it is.
- 1:11We observe a medical problem, a behavior, a weird animal, a
- 1:14weird thing, in the stars, whatever it is. So we have observed
- 1:18whatever this phenomenon is, and we want to know more about that thing.
- 1:21And it doesn't have to be seen, like we have people who do not
- 1:23have vision who can participate in science any way that you can observe or measure
- 1:26or detect something. But yes, we encounter a thing, I guess.
- 1:30Yes, let's go with the observation that in the United States more than forty
- 1:36eight thousand people died of gun violence in twenty twenty one. That's just an
- 1:40observation. Yeah, I'm not making any qualitative statements about it. I'm not
- 1:42making any judgments about it. I'm just saying that's the thing that happened.
- 1:46More than forty eight thousand people died of gun violence in the United States in
- 1:49twenty twenty one. That is a problem that we can detect with data.
- 1:53I mean, that's just kind of what we're saying right now. So then
- 1:57what happens is we go to our second step, which is that we form
- 2:00a hypothesis about a thing. And so a hypothesis is a statement that possibly
- 2:04explains a phenomenon. We want to explore that hypothesis a little bit, right,
- 2:07So a hypothesis is a statement that is a tentative guess about relative factors
- 2:13and variables that may be attributable to that observation. Right, So that's what
- 2:17a hypothesis is. This is just sort of a tentative guess. We're just
- 2:21sort of saying this, like, this could be what's going on here,
- 2:23maybe the reason for the thing that we're seeing. We're on the gun violence
- 2:27saying one may hypothesize that the reason there are so many gun related deaths is
- 2:31because there are not enough guns, and if we had more guns, there
- 2:35would be fewer deaths by gun violence. That's a hypothesis. We could say
- 2:38that that might be the case of what's going on. Yeah, I mean
- 2:40that that is a hypothesis. I'll say that good or bad or otherwise.
- 2:46I will say that it is a hypothesis. As we go forward, though,
- 2:49the third step is that after we encounter the observation, or we've had
- 2:53enough observations, I should say a scientific law can be described. So a
- 2:57law is a statement about the constant parameter associated with data collected about a phenomenon.
- 3:01So laws are often summarized as equations. So we start kind of looking
- 3:06at those the laws are usually some kind of there's usually a sigma involved in
- 3:09there. There's definitely equal signs, but we have some kind of equation that
- 3:13describes, like this, this is how we know about this thing. Here.
- 3:15The parameter is the rules, the guidelines. Yeah. So, as
- 3:19an example, when early aeronauts were explaining we're experimenting, not explaining, but
- 3:23they were just experimenting with hot air balloons, they discovered that whenever a gaseous
- 3:28element was heated, it expands. Gases expand when heated. This relationship can
- 3:31be described as a law because it was so constant to say, whenever this
- 3:36thing happens, this thing happens. Whenever we would apply heat to a gas,
- 3:38the gas expands. That just happens, right, And so that was
- 3:40consistent enough that it was just it wasn't saying why it happened. It wasn't
- 3:45saying how it happened. It's just saying, this is a thing that seems
- 3:47to pretty much always happen in this context. Right. And so another example
- 3:53of that is how the law of conservation of energy states that energy cannot be
- 3:55created or destroyed. So basically energy equals energy and the equal sign is there.
- 4:01It's not crossed out because it does equal to the same thing, so
- 4:03you can't get rid of it. You know, the equation is always balanced,
- 4:06is what I'm saying. Yeah. Yeah, and they kind of specifying
- 4:10an internal closed system, et cetera. But you know whatever, that is
- 4:13the law of conservation of energy, that's different. That's the whole everything in
- 4:15the matching law. To an episode that we did recently on the matching law,
- 4:18the states that the rate of behavior will approximately match the available rate of
- 4:23delivered reinforcement. So there's a correspondence there. So that's that is a law
- 4:27that states that those two things tend to go together in that way. Right.
- 4:30And then in a twenty nineteen study, they found that for every one
- 4:34percent that gun ownership increased, there is a point nine percent increase in the
- 4:39rate of homicides. So they were able to describe that as a pretty clear
- 4:44equation. Yeah. So again, it's not making any value statements about it.
- 4:47It's not saying why or how it happens. All it is saying is
- 4:50like, this is an observation that we made this thing happens, and this
- 4:54thing happens, and they happened at about this rate pretty consistently. So there's
- 4:57that, right, We need to get to signentific theory. But first we'll
- 5:00take a quick advertisement break. Okay. So we talked about observation, then
- 5:12we talked about a hypothesis, and then we described a law, and so
- 5:15finally there is scientific theory, the redheaded stepchild of scientific descriptions among sort of
- 5:24the public, not among scientists. Yeah, and how often have we heard
- 5:28the derelict rejoinder? That's just a theory when someone is challenged with scientifically validated
- 5:34counter evidence too often in my opinion. Yeah. In science, though,
- 5:40a theory is a statement that describes, first of all, that summarizes an
- 5:44enormous body of data, and it describes how and why something happened based on
- 5:48just such overwhelming evidence that it is unlikely to be falsefied in the near future,
- 5:56if ever. Right, So, things like stating the sun will rise
- 6:00tomorrow, or more accurately, that the part of the Earth on which you
- 6:03are stationed will rotate towards the Sun again within the next twenty four hours is
- 6:08basically a theory constructed on such massively incontrovertible evidence. It's a sound as fact.
- 6:13It's basically we know this to be true. It's as true as it
- 6:16could possibly get at this point in time. Yes, stating that everyone who
- 6:20lives will eventually die. It's just a theory, a theory that is so
- 6:24well established by the evidence that we simply know that it is true. Right.
- 6:28Evolution is so well established by data that we simply know that it's true.
- 6:32That's why we have thumbs y'all. Climate change is so well established by
- 6:36the data of specifically anthropogenic or human cause. Climate change is so well established
- 6:42by the data that we simply know that it is true. Uh huh.
- 6:45The fact that the world is spherical, Yeah, I mean it's an irregularly
- 6:48shaped ellipsoid nerds, it's a ball floating in space. But that's actually so
- 6:55well established by the overwhelming amount of evidence that we simply know it to be
- 6:58true. Theory is so well established by the evidence that we simply know it
- 7:02to be true. Right, So calling something just a theory should be one
- 7:05of the highest forms of praise and endorsements about whatever your topic you're talking about,
- 7:11Because if something is a theory, that means has gone through all of
- 7:14the scientific rigor, or quite a bit of it, enough to solidify it
- 7:17into the scientific lexicon. Yeah, basically you could say that's just a fact,
- 7:21and you'd be saying as something as critical as saying that's just a theory.
- 7:26Right, so someone's talking about evolution and they say that's just a theory,
- 7:29then they basically just said that's just a fact, and you know it
- 7:31is, it is just a fact. You're right, You're right. Good,
- 7:35glad we're on the same page. Well, we've been talking about gun
- 7:39violence, so I guess we may as well not leave you hangling gun death
- 7:42violence. Unfortunately, this is where we have we sort of run out of
- 7:46things we talked about. We have an observation, we had a hypothesis,
- 7:49we had a what is almost a law. There's needs more data to be
- 7:54substantiated, but you know there's data we're collected. So the issue here is
- 7:58when we get into theory, we don't exactly know what kinds of policies or
- 8:01laws would reduce needless deaths by guns. Some countries have worse gun violence than
- 8:05the United States, but some have far less gun violence than the United States.
- 8:09And unfortunately, in the United States, we can't research it because people
- 8:13have enacted legislation to make it illegal to do research on gun violence here,
- 8:18so we just won't know what we could possibly do about it. All we
- 8:22have right now is our observations, our hypotheses, and our data that have
- 8:26been collected that, as we said, are simply correlational at this point.
- 8:30So there is certainly more to be learned, but just to say, like,
- 8:33that's as far as it has gotten. We don't have a solution for
- 8:37it. Sorry, it's unfortunately, but this was not an episode on gun
- 8:39violence. This was an episode on theories and scientific understanding. And so the
- 8:43point is a hypothesis is the point at which we know the least amount of
- 8:48something. A law is a description about how things work that is basically always
- 8:52true, and a theory is an explanation of phenomenons so overwhelmingly supported by evidence
- 8:58that it is a fact. That is the fact. And so thank you
- 9:03for listening to our mini I think that's all I got. Anything you'd like
- 9:05to add before we le everyone go, Shane, I think we're good.
- 9:07You know I have it on good authority. It's a theory that we're good,
- 9:11just a fact. Great, Well, then, thank you all for
- 9:15listening, Thank you for recording with me today. Shane. Why we do
