I have a liberal arts background. So I use the term research to mean gathering evidence, evaluating its trustworthiness and biases, and avoiding related thinking errors related to evaluating evidence (https://thedecisionlab.com/biases).
LLMs can fall prey to these problems as well. Usually it’s not just “reasoning” that gives you trouble. It’s the reasoning about evidence. I see this with Claude Code a lot. It can sometimes create some weird code, hallucinating functionality that doesn’t exist, all because it found a random forum post.
I realize though that the term is pretty overloaded :)
Same here. But it often produces broken or bogus links.
I'd love if it had a confidence rating based on the sources it found or something, but I imagine that would be really difficult to get right.
AI really needs better source-validation. Not just to combat the hallucination of sources (which gemini seems to do 80% of the time), but also to combat low quality sources that happen to correlate well to the question in the prompt.
It's similar to Google having to fight SEO spam blogs, they now need to do the same in the output of their models.
Kagi also tells you the percentages “used” for each source and cites them in line.
It’s not perfect, but it’s a lot better to narrow down what you want to get out of your prompt.
No API access though so you're stuck talking with it through the webapp.
When LLMs really started to show themselves, there was a big debate about what is truth, with even HN joining in on heated debates on the number of sexes or genders a dog may have and if it was okay or not for ChatGPT to respond with a binary answer.
On one hand, I did found those discussions insufferable, but the deeper question - what is truth and how do we automated the extraction of truth from corpora - is super important and somehow completely disappeared from the LLM discourse.
If you ask for information which is e.g. academic or technical it would cite information and compare different results, etc, without any extra prompt or reminder.
Grok 4 (at the initial release) was just reporting information in the articles it found without any analysis.
Claude Opus 4 also seems bad: I asked it to give a list of JS libraries of a certain kind in deep research mode, and it returned a document focused on market share and usage statistics. Looks like it stumbled upon some articles of that kind and got carried away by it. Quite bizarre.
So GPT-5 is really good in comparison. Maybe not perfect in all situations, but perhaps better than an average human
Alas, the average human is pretty bad at these things.
This is what I keep finding, it mostly repeats surface level "common knowledge." It usually take a few back and forths to get to whether or not something is actually true - asking for the numbers, asking for the sources, asking for the excerpt from the sources where they actually provide that information, verifying to make sure it's not hallucinating, etc. A lot of the time, it turns out its initial response was completely wrong.
I imagine most people just take the initial (often wrong) response at face value, though, especially since it tends to repeat what most people already believe.
This cuts both ways. I have yet to find an opinion or fact I could not make chatgpt agree with as if objectivly true. Knowing how to trigger (im)partial thought is a skill in and of itself and something we need to be teaching in school asap. (Which some already are in 1 way or another)
There was a recent discussion about Wikipedia here recently where a lot of people who are active on the site argued against people taking the claims there with a grain of salt and verifying the accuracy for themselves.
We can teach these things until the cows come home, but it's not going to make a difference if people say it's a good idea and then immediately do the opposite.
If you mean whether Wikipedia is unreliable? That's a different story, everything is unreliable. Wikipedia just happens to be potentially less unreliable than many (typically) (if used correctly) (#include caveats.h) .
Sources are like power tools. Use them with respect and caution.
You are very optimistic.
Look at all other skills we are trying to teach in school. 'Critical thinking' has been at the top of nearly every curriculum you can point a finger at for quite a while now. To minimal effect.
Or just look at how much math we are trying to teach the kids, and what they actually retain.
Critical thinking is a much more general skill which is applicable anywhere, thus quicker to be 'buried' under other learned behavior.
This skill has an obvious trigger; you're using AI, which means you should be aware of this.
I’ve found ChatGPT and other LLMS can struggle to evaluate evidence - to understand the biases behind sources - ie taking data from a sketchy think tank as gospel. I also have found in my work the more reasoning, the more hallucination. Especially when gathering many statistics.
That plus the usual sycophancy can cause the model to really want to find evidence to support your position. Even if you don’t think you’re asking a leading question, it can really want to answer your question in the affirmative.
I always ask ChatGPT do directly cite and evaluate sources. And try to get it in the mindset of comparing and contrasting arguments for and against. And I find I must argue against its points to see how it reacts.
