Latest / Safe As Podcast / EP33: Is ChatGPT bullsh** you? How Large Language models aim to be convincing rather than truthful
Transcript
- 0:06You've luckily heard of how large language models like
- 0:09ChatGPT, Google, Gemini Copilot, etcetera have factual errors
- 0:15called hallucinations, a term that's become popular in both
- 0:19technical and general contexts. But what if that term is
- 0:22misleading? What if the hallucinations are
- 0:25better described as bullshit? G'day everyone, I'm Ben
- 0:29Hutchinson and This is Safe as a podcast dedicated to the thrifty
- 0:33analysis of safety, risk, and performance research.

- 0:40Today's article is from Hicks ET al 2024 titled ChatGPT is
- 0:47Bullshit published in Ethics and Information Technology.
- 0:51The core argument is that when ChatGPT and similar large
- 0:54language models produce false claims, they're not lying or
- 0:58hallucinating, but more precisely, the activity they're
- 1:02engaged in is more like bullshitting in the sense
- 1:05explored by philosopher Harry Frankfurt.
- 1:07For these authors, this is a crucial distinction, as the way
- 1:11we describe new technology, even metaphorically, profoundly
- 1:16shapes how policy makers and the public understand and apply it.
- 1:20So why do they argue against the prevalent term hallucinations?
- 1:25Why not hallucinations? The term hallucination suggests
- 1:28that these systems are misrepresenting the world or
- 1:32describing what they say, which is an inept metaphor that
- 1:35misinforms. It anthropomorphizes large
- 1:39language models, attributing to them sort of a life or human
- 1:44like perceptual experience that they simply don't have.
- 1:47Large language models don't perceive, so they cannot
- 1:50misperceive. Crucially, this term implies
- 1:54that a factual error is an unusual or deviant form of the
- 1:58large language models of the way they process.
- 2:01In reality, the very same process occurs when it's outputs
- 2:05happen to be true. Furthermore, attributing
- 2:08problems to hallucinations can allow creators to blame the AI
- 2:12model for faulty outputs instead of taking some sort of
- 2:15responsibility over the behaviour of the AI.
- 2:18It also suggests ineffective solutions like trying to connect
- 2:22the AI to real rather than hallucinated sources, which
- 2:26according to the authors, has largely failed.
- 2:29If we wrongly assume it perceives things, we might try
- 2:32to correct its beliefs or fix its inputs, strategies that have
- 2:36yielded limited, if any, success.
- 2:39Ultimately, calling inaccuracies hallucinations can feed these
- 2:43overblown hype trends and lead to unnecessary consternation or
- 2:47misguided efforts at AI alignment among specialists.
- 2:51So why can't we call them lies critically?
- 2:54So lying requires an intention to save someone to believing a
- 2:58false statement. Large language models are simply
- 3:01not designed to accurately represent the world the way it
- 3:04is. They cannot be concerned with
- 3:07truth according to the authors, even if ChatGPT could be
- 3:10described as having intentions, which is a complex philosophical
- 3:15question, it's not designed to produce true utterances, but
- 3:19rather text that's indistinguishable from the text
- 3:22produced by humans. Therefore, it's aim is to be
- 3:25convincing, not accurate. So this brings us to the topic
- 3:29of bullshit. What exactly is bullshit in this
- 3:32Frankfurtian sense, and how does it apply to large language
- 3:35models? So, according to Frankfurt, the
- 3:38defining feature of bullshit is a lack of concern with truth, or
- 3:42an indifference to how things really are.
- 3:45It's not about actively trying to deceive, but rather having no
- 3:49regard for the truth. The authors highlight that large
- 3:52language models cannot themselves be concerned with
- 3:54truth, and because they're designed to produce texts that
- 3:58without any actual concern for truth, it seems appropriate to
- 4:01call their outputs bullshit. Their primary goal, if they have
- 4:04one, is to produce human like text by estimating the
- 4:08likelihood that a particular word will appear next.
- 4:11They're built on massive statistical models of text, and
- 4:15when these models produce text, it looks at the previous words,
- 4:19constructs A context, and then produces a set of likelihoods
- 4:23for the next word. So this process explains why
- 4:26large language models have a problem with the truth.
- 4:28According to the paper, their goal is to provide a normal
- 4:32seeming response to a prompt, but not to convey information
- 4:35that's helpful to the user. Examples include lawyers citing
- 4:39bogus judicial decisions and academic researchers receiving
- 4:43fake references. These errors can then even
- 4:46snowball. The problem isn't that the large
- 4:48language models misrepresent the world, it's that they are not
- 4:51designed to represent the world at all.
- 4:54Instead, they're designed to convey convincing lines of text.
- 4:58Now, this paper also distinguishes two types of
- 5:00bullshit. It talks about soft bullshit,
- 5:03which is characterised by an indifference towards the truth
- 5:06of the utterance, but without the intention to mislead the
- 5:09hearer regarding the utterer's agenda.
- 5:13The authors are quite certain that ChatGPT does not intend to
- 5:15convey truths, and so in their words, it's more of a soft
- 5:18bullshitter. If it has no intentions, it
- 5:21trivially doesn't intend to convey truths, and it's
- 5:24indifferent to them. If it does have intentions, it's
- 5:28still designed to be convincing rather than accurate, which
- 5:30aligns with soft bullshit. So they conclude that, at a
- 5:33minimum, ChatGPT is a soft bullshitter.
- 5:37Bullshit that is speech or text produced without concern for its
- 5:41truth. And it's produced without any
- 5:43intent to mislead the audience about the Utter's attitude
- 5:46towards truth. There's also hard bullshit,
- 5:50which they think is more of a controversial claim.
- 5:52Hard bullshit is produced with the intention to mislead the
- 5:55audience about the Utter's agenda.
- 5:57This involves a higher order deception about what the
- 6:00bullshitter is up to. But the ChatGPT is a hard
- 6:03bullshitter depends on whether it can be ascribed intentions.
- 6:06The authors suggest that there is a robust, although maybe
- 6:09perhaps not literal, sense in which ChatGPT does intend to
- 6:13deceive us about its agenda. Its goal isn't to convince us of
- 6:17the content and what it says, but instead to portray itself as
- 6:21a normal agent like us, human like qualities.
- 6:25They argue that Chat GPT's primary function is to imitate
- 6:28human speech. If this function is considered
- 6:31intentional, then ChatGPT is attempting to deceive the
- 6:34audience about its agenda by largely trying to seem like
- 6:38something that has an agenda when in many cases it doesn't.
- 6:41Ultimately, the authors conclude that regardless of whether or
- 6:44not programme has intentions, it clearly isn't attempted to save
- 6:48the hearer or reader about the nature of sort of the enterprise
- 6:52somewhere along the line around what the agent is, and in their
- 6:56view it justifies calling the output hard bullshit.
- 6:59So, according to paper, minimally, it churns out soft
- 7:03bullshit, and given certain controversial assumptions about
- 7:07the nature of intentional description, it produces hard
- 7:10bullshit. The specific texture of the
- 7:12bullshit is not, for these purposes, important.
- 7:15Either way, Cha chi PT, again their words, is a bullshitter.
- 7:20Next they talk about why this matters.
- 7:22Well, why doesn't matter. They say it because indifference
- 7:25to the truth is extremely dangerous.
- 7:28For instance, civilised life and vital institutions depend very
- 7:32fundamentally on respect for the distinction between the true and
- 7:36the false. When the authority of this
- 7:39distinction is undermined by the prevalence of bullshit by
- 7:42treating large language models as if they are concerned with
- 7:45truth or metaphorically suffering hallucinations, we
- 7:49risk accepting this bullshit and allowing this squandering of
- 7:51meaning. Calling these inaccuracies
- 7:53bullshit rather than hallucinations isn't just more
- 7:56accurate in their view, it's good science and technology
- 7:59communication in an area that really urgently needs this sort
- 8:03of guidance. It helps us understand that even
- 8:06when a large language model gets things right, it's still
- 8:09bullshitting as it's accuracy is incidental to its design.
- 8:13So in conclusion, understanding Chechi PTS output is bullshit
- 8:17means recognising that these models are designed to generate
- 8:20convincing text, not to convey truth or falsehood.
- 8:25This framing is vital for investors and policy makers and
- 8:28the public to make informed decisions about how to engage
- 8:31with these powerful systems. That's it on SAFE As I'm Ben
