Hallucinations are a well known problem. And there are some mitigations that work pretty well. Mostly with enough context and prompt engineering, LLMs can be pretty reliable. And obscure popular fiction trivia is maybe not that relevant for every use case. Which would be robotics in this case; not the finer points of Michael Crighton related trivia.
You were testing its knowledge, not its ability to reason or classify things it sees. I asked the same question to perplexity.ai. If you use the free version, it uses less advanced LLMs but it compensates with prompt engineering and making it do a search to come up with this answer:
> The Gell-Mann Amnesia effect is a psychological phenomenon that describes people's tendency to trust media reports on unfamiliar topics despite recognizing inaccuracies in articles about subjects they know well. This effect, coined by novelist Michael Crichton, highlights a cognitive bias in how we consume news and information.
Sounds good to me. And it got me a nice reference to something called the portal wiki, and another one for the same wikipedia article you cited. And a few more references. And it goes on a bit to explain how it works. And I get your finer point here that I shouldn't believe everything I read. Luckily, my supervisor worked hard to train that out of me when I was doing a Ph. D. back in the day. But fair point and well made.
Anyway, this is a good example of how to mitigate hallucination with this specific question (and similar ones). Kind of the use case perplexity.ai was made to solve. I use it a lot. In my experience it does a great job figuring out the right references and extracting information from those. It can even address some fairly detailed questions. But especially on the freemium plan, you will run into limitations related to reasoning with what it extracts (you can pay them to use better models). And it helps to click on the links it provides to double check.
For things that involve reasoning (like coding), I use different tools. Different topic so won't bore you with that.
But what figure.ai is doing, falls well in the scope of several things openai does very well that you can use via their API. It's not going to be perfect for everything. But there probably is a lot that it nails without too much effort. I've done some things with their APIs that worked fairly well at least.
