Scientists should use AI as a tool, not an oracle
- benhoyt 2y ago> People should use AI as a tool, not an oracle There, fixed the title.
- az09mugen 2y agoPeople must not use AI as an oracle, but rather as a tool. I think this is even better

- throwanem 2y agoIf this is already such a problem even in the professional discipline and vocation whose sine qua non is the accurate analysis of physical reality, I'm really nervous about the next few years. And I was nervous already...
- LouisSayers 2y agoNot just scientists, but everyone! My partner recently went a bit nuts writing an article with the help of GPT4. She was very proud of how productive she'd been until I asked if she'd actually searched for the papers GPT4 had referred to. Of course, many of the referred to papers didn't exist...
- JeremyBarbosa 2y agoSadly it's not even just references, LLMs still hallucinate or at least misrepresent even the most basic of facts. That and the stereotypical GPT-verbage makes it impossible to use for writing anything significant.
- SrslyJosh 2y ago> LLMs still hallucinate Keep in mind that there's no difference between what happens inside a model when it "hallucinates" vs. when it generates "correct" output. It's the exact same process.
- alpinisme 2y agoThat’s true, but it’s also true of anything else that makes mistakes, including buggy software. When a buggy sorting algorithm produces a bad ordering it’s doing so “with the exact same process” the good ordering is coming from. Ditto for humans and their slips (although tbh I get a little tired of the analogizing of humans and llms…not that the analogies are wrong, but just that we always analogize human minds with the latest technology: wax writing pads through computers)
- raincole 2y agoUh... yes? I'm not sure why it's some significant insight. Surely when google gives bad results, it's "the same process" as when it gives good results. And when a book gives wrong information, it's the exact same kind of ink as correct information.
- Terr_ 2y agoI think the point is that it's not some kind of bug to find and fix, it's a fundamental risk with the entire approach.
- switchbak 2y agoWe were already swimming in a world of bullshit prior to the wide availability of these. I'm not sure what the future holds, but I think intelligent people are going to become very skeptical of virtually all information sources. I would imagine there's also a raft of people who will use it as a reason to give up on any search for truth. I still do hold a lot of hope for their eventual capabilities, but I'm also pretty pessimistic on what the direct and Nth order social effects will be.
- flatline 2y agoThat is not writing with the help of GPT 4, that is letting it write for you! I can’t imagine doing anything creative and letting a computer source material for me without having reviewed the material first hand, even if it was accurate. Clearly, this is not where everyone’s head is at, and I suspect your wife’s workflow is more the common case. I’ve said from the outset that in academic settings you should be able to cite an AI as a writing assistant, it would clear up a lot of the confusion about its use. If you used it poorly it’s still on you, but at least there’s some transparency by which to judge the work.
- Mathnerd314 2y agoI've sort of worked out a workflow. Like say I had to write an essay and take a side for/against something. Then I would ask GPT to write the strongest argument for, and the strongest argument against, telling it to make up whatever sources it wants. Then after reading those, I would have some idea of my own opinions. I would write from scratch but with the GPT for/against pulled up alongside as reference for how to structure the arguments. Then I would put it through GPT again for proofreading and grammar (or just spelling, if there is AI detection software). It is a bit tricky though, there are definitely points that come up with GPT that people would not think of normally. So in that sense it is still distinguishable from writing solely by oneself, but I would argue the GPT-assisted essays are just better writing and more well-rounded.
- bsenftner 2y agoThere is a subtle aspect of LLM AIs that is lost to most people: they are trained on the entirety of the Internet. That means whatever topic you ask these LLM AIs, there are multiple instances of that same information with different levels of seriousness and accuracy in their treatment of the subject. For example: if one asks a question using street slang, the answer generated will be generated from training data about your subject, but from online sources that used street slang in their conversation about that issue. Likewise, if you use ordinary language for your question, the generated response will be from ordinary language conversations of your topic. However, if your question concerns any type of formalized knowledge, by asking your question using the formal language of experts in that topic, then the generated AI answer will come from training data that used this same formal expert terms, and are most likely to be correct, because they come from discussions of that subject’s matter experts. Plus, don't use LLMs for fact retrieval, use them as strategy guides. They really excel as strategy advisors.
- EGreg 2y agoHmm. In the future the AI in nefarious hands can retroactively make the papers first, and get them past the censors. Just make up a lot of bullshit and then it’s turtles all the way down lmao
- Terr_ 2y agoI'm imagining how much easier it would have made work for the Ministry of Truth in 1984.
- deleted 2y ago[deleted]
- colechristensen 2y agoGPT-whatever can’t do sources. I was trying to use it as a research tool and it hallucinated 95% of the references I asked for (not a made up percentage, I counted) Ironically the one real source turned out to be quite useful.
- unkulunkulu 2y ago> Unfortunately, most scientific fields have succumbed to AI hype, leading to a suspension of common sense. For example, a line of research in political science claimed to predict the onset of civil war with an accuracy2 of well over 90%, a number that should sound facially impossible. (It turned out to be leakage, which is what got us interested in this whole line of research.) This coupled with people acting on its predictions is a kind of self fulfilling prophecy. which is to ask, are AI safety folks building models of this pattern? :)
- throwanem 2y agoHow would that work, do you think?
- wegfawefgawefg 2y agoIf you knew everyone would ask gpt before doing anything, you would make gpt say what woudl generally be considered the better option. Not going to war, not committing suicide, etc. In this way even if war was the optimal decision according to some other utility function, the behavior of people is directed in a positive way. (Presumably)
- throwanem 2y agoSure, if you also assume people follow whatever advice so given. They won't, even before the covert influence effort becomes popular knowledge, as it inevitably will. This destroys consumer trust in your product after you have successfully made that product indispensable, thus opening up a previously impossible vacuum in epistemology and thus access to power.
- wegfawefgawefg 2y agoFor the record I believe it to be immoral to manipulate humanity in this way. And I also believe it might be bad for bussiness. I was just trying to explain to the guy above what I think the guy above that meant.
- bbor 2y agoWow I came into this article angry, idk if their book title accurately conveys the sober, expert analysis it contains! In case anyone else is curious why they’re talking about “leakage” in the first place instead of the existing term “model bias”, here’s the paper they cite in the “compelling evidence” paper that started these two’s saga with the snake oil salesmen: https://www.cs.umb.edu/~ding/history/470_670_fall_2011/papers/cs670_Tran_PreferredPaper_LeakingInDataMining.pdf https://www.cs.umb.edu/~ding/history/470_670_fall_2011/paper... Crux passage: > Our focus here is on leakage, which is a specific form of illegitimacy that is an intrinsic property of the observational inputs of a model. This form of illegitimacy remains partly abstract, but could be further defined as follows: Let u be some random variable. We say a second random variable v is u-legitimate if v is observable to the client for the purpose of inferring u. In this case we write v € legit{u}. > A fully concrete meaning of legitimacy is built-in to any specific inference problem. The trivial legitimacy rule, going back to the first example of leakage given in Section 1, is that the target itself must never be used for inference: > (1) y !€ legit{y} So ultimately this all about bad experimental discipline re: training and test data, in an abstract way? I’ve been staring at this paper for way too long trying to figure out what exactly each “target” is and how it leaks, but I hope that engineering-translation is close
- duxup 2y agoWe use search that way, don’t see why AI trained on similar content wouldn’t be just variable in terms of reliability.
- skywhopper 2y agoThis is incredibly simplistic. Search engine results give a lot of context clues about the reliability of their asserted facts and provide a potential spectrum of answers. LLM-generated answers strip all that away, and give a single authoritatively phrased answer. Even if you’re inclined to disbelieve it, the LLM answer gives you no ability to dig in, refine, or compare. It just is. If you ask a chatbot if it’s sure, it might double down, or apologize and then repeat itself, or say it was right and give a contradictory followup. Traditional pre-spam-overload Google results could often give a high quality answer, or if not, you’d at least get the sense of the low quality. Not so with LLMs.
- duxup 2y agoI think you overestimate people’s ability to sniff out bad data on the internet. Also are you suggesting people fact check an AI by asking it if it is correct? That seems absurd.
- threeseed 2y agoBut you could trust certain websites being more accurate than others based on their brand, the author, the other content the site had published, who they are linking to and people linking to them etc. LLMs remove that ability to be discerning about what to trust.
- dotnet00 2y agoPre-LLM madness, most decent scientists were capable of judging the reliability of a source, at least to an extent. Eg if the source is a paper in a decent journal, it probably has at least some substance to it and the basic facts are probably not wrong, if the paper is a zero-citation paper on vixra where none of the authors have any reasonable history, you'll probably have to check everything.
- TheRoque 2y agoThe worst is having random people questioning your expertise because of what ChatGPT told them.
- godelski 2y agoTo be fair, people did this before ChatGPT. It's just the thing they point to as evidence now, and they'll always find something. The underlying problem is much bigger: 1) people confidently arguing with domain experts about topics that they have little to no experience in. 2) people valuing the opinions of arguers from 1 over experts.
- alvah 2y agoTo be extra fair, "domain experts" in some areas have had a bad few years; there are a couple of fields I can think of off the top of my head where the "experts" wheeled out to advise/scare the public are clearly more influenced by politics (or saving their own skin) than science. Replacing trust in experts with trust in LLMs is obviously dumb, but who is Joe Sixpack supposed to turn to?
- godelski 2y agoI'm not sure which domains you're referring to. I can think of domains where sensationalist opinions are lifted, but not ones where the general consensus is blatantly false. I can think of plenty of instances where large news organizations have grossly misrepresented conclusions of research. > but who is Joe Sixpack supposed to turn to? This, I agree with. It is why I actively voice dissent, as an expert and in areas where I have domain expertise, against so-called science communicators (not all are "so-called") and when the news gets it wrong. Hell, I'll do this when actual science communicators get it wrong. Like when Niel DeGrassee Tyson is being dumb[0]. He also thinks hydrogen bombs don't have fallout...[1]. They do... That said, I still don't think this is a reason to distrust scientists. But I think it is important for scientists to speak out when communicators get it wrong. I think this is a common problem and allows the conmen to gain power. But that's not the only force at play. Truth is complex. Approximate truth is bounded in complexity. But lies can be infinitely simple. So we get it wrong when we "reason our way through" something, because typically the base assumptions are wrong. This makes many conmen truly believe the lies that they are selling. Joe Sixpack can reason through that. But Joe Sixpack can also reason through the concept that if he was easily able to reason through something and that experts disagree, it's pretty likely there's a reason why other than them being dumb and <Joe Sixpack> knowing better. Can, but doesn't. And we as the public let that happen. This may seem like an insurmountable problem, but instead it is a problem which just needs sufficient effort. Momentum builds, so the more people that push against this, the more common it'll become. And to be clear, it is perfectly fine to question experts. It is not perfectly fine to confidently disagree while not actually understanding the topic. If you don't know the difference, read a few papers/works in the topic and see if you can understand 90+% of it (if it is CS or Engineering, see if you can replicate).

- dluan 2y agoScientists have been obsessed with over-optimzing for FOMO for the past decade - what papers should I read that I don't have time for, what grants should I apply for that I don't know about, what projects should I work on that will give me the best ROI, who in my field is poised to disrupt or make a big leap, etc. Some even think that the end goal is actually an autonomous research agent that can make decisions about what questions to ask and why, and that's one of the true marks of AGI. That to me is insane and misses the entire point of science altogether, even once we reach that technical feasibility. We ask questions about the universe to expand our human relationship with the universe, not to just amass more research capital for the sake of it. And the fact that the AI snake oil has infected big chunks of science reveals which parts of it are just gold rush speculation and which aren't. There's a more fundamental challenge of training scientists to understand why we ask the questions we ask. You can't just offload that to some background task and trust that it makes sense.
- Onawa 2y agoI understand the point that you're making about overoptimizing for FOMO in science. I wanted to give you another perspective from a scientist working within the US government that doesn't care about playing that game. Our governmental research agency, and NIH as a whole has TONS of research data that we don't have the manpower to screen and provess. There are also gaps in data that AI/ML could help us simulate. AI research assistants could potentially help us process and evaluate "what questions to ask" by, for example, looking for trends in QSAR (quantitative structure-activity relationship) models for novel chemicals and help us direct our attention to compounds of toxicological interest. We've also been trying to use the AI research assistants to speed up the process of evaluating the scientific literature for toxicologists who have to make regulatory decisions. Our agency has a backlog of chemicals that we would love to evaluate, but lacks the manpower to do so. No profit motive or much "clout" interest, at least that I've seen. Just a lot of public servant scientists who need some extra help protecting the public.
- captainkrtek 2y agoIn my professional work, I treat chatgpt as a search engine that I feel I can ask questions of in a natural manner. I often find small flaws in technical solutions it offers, but it can still provide useful starting points to investigate. I rarely trust code it generates (at least for the language I mainly work in) as i’ve seen it make some serious mistakes (eg: using keywords in the language that don’t exist)
- SrslyJosh 2y ago> I rarely trust code it generates (at least for the language I mainly work in) as i’ve seen it make some serious mistakes (eg: using keywords in the language that don’t exist) It's only a mistake from your perspective. The model just generates text based the probabilities it learned during training. In that respect, there is no such thing as "incorrect" output because the model doesn't operate at that level of abstraction.
- tikhonj 2y agoThat's like saying "there is no such thing as a bug, it's just code working the way it was written"—true in some sense, but not useful.
- LordKeren 2y agoWhile yes, this is the technical reason — it’s important to not overlook how non-technical people see LLMs. And not only that, how they are being marketed. I’m struggling to think of any comparable technology where the regular median users understanding is both fundamentally wrong— and is being purposefully misinformed.
- tombert 2y agoWait, no, it's "incorrect" in the sense that you asked it to do something, and the thing it gives you doesn't accomplish the task. I asked it "what is the PS3 game where the full version of To Kill a Mockingbird is in there?" and it responded back with "The Sabateour", when the correct answer would have been "The Darkness". That is incorrect by most definitions of the word, whether or not it's a consequence of the training model doesn't really change that. I suppose we could get into details about epistemology and ontology about the nature of what an answer "is", but I think it's fair to say that "incorrect" is when it gives you something that doesn't accomplish the task you asked it to do, or rather when it tries to accomplish the task but what it gives you don't work.
- shmatt 2y agoI feel like 90% of AI discussions online these days can be shut down with “a probabilistic syllable generator is not intelligence”
- WalterSear 2y agoThat hasn't worked for me.
- Zambyte 2y agoHumans are not fact machines, we are often wrong. Do humans not have intelligence? What do you even mean by "intelligence" when you say a probabilistic syllable generator "is not intelligence"?
- dotnet00 2y agoLike clockwork, out come the "but humans" deflections. An LLM is not a human-like intelligence. This is patently obvious, such comparisons are nonsensical and just further the problem of people anthropomorphizing a tool and treating it like an oracle.
- Zambyte 2y agoYou didn't answer the question.
- dotnet00 2y agoI did, I said they aren't human-like intelligences, so countering with "humans make mistakes, are humans not intelligent?" is drawing a false equivalence between humans and LLMs. Since we do not possess a definition of intelligence that isn't human-like, it would be meaningless to argue if LLMs are intelligent in general. All that can be said is that they are not intelligent in the way that humans are.
- Zambyte 2y agoThe question you answered was rhetorical; obviously humans are intelligent. There is another question that actually has an interesting answer after it. In fact, it's not possible to have a meaningful discussion without answering it. I thought that was obvious :)
- m3kw9 2y agoTo know when to be skeptical to LLMs you have to know how it is trained and inferenced, and you have to use it often to see how it can screw up
- logrot 2y agoBut surely if it's artificial intelligence then it'd know its limits and would respond appropriately? Oracle use no problem? It is it because it's actually shit but it's the best thing we've seen yet and everyone is just in denial?
- mewpmewp2 2y agoPeople constantly misevaluate their own limits though. Why should AI not be allowed to do that?
- deleted 2y ago[deleted]
- Jensson 2y agoProfessionals don't constantly misevaluate their limits, if the AI is to replace a professional it has to know its limits.
- mewpmewp2 2y agoCurrent AI is for productivity boost, not to replace. And automation of certain use cases, but not all. It is already really good at those things.
- threeseed 2y agoIt depends on who you mean. Most normal people look at AI like ChatGPT as an amazing tool and have used it effectively as a replacement for Google, Grammarly etc. And for them it's fine because any mistakes are localised to them. The problem are those building products on LLMs e.g. Legal, Customer Service who are knowingly misrepresenting the capabilities of what it can do to companies who don't know any better. And I would argue this is fraudulent and where we will see most of the problems.
- cdme 2y agoIt's marketed and sold as an oracle. The AGI crowd feels like a cult.
- skrap 2y ago...but why wouldn't they use AI as an oracle? From an outsider's perspective, it seems that there's already plenty of incentive to test the margins of acceptable academic practice in order to produce more papers or publish more quickly. Sadly I feel like it'll become the norm to have a chatbot interpret your results and write your paper rather than using those expensive grad students. I don't have answers; just the lingering question "why are we building this?"
- Kalium 2y agoWe're building this because the ability to make narrow, specific predictions can be narrowly and specifically useful. This works if you have a good understanding of both the tools and the domain you're looking to make predictions in. Unfortunately, from an outsider perspective, this looks like being widely and generically useful. If you don't understand your tools, you're going to misuse them, and this hype cycle is the result.
- teknopaul 2y agoNo shit sherlock
- 10000truths 2y agoIs "leakage" just another term for overfitting?
- XenophileJKO 2y agoNo usually it means the data that you intend to test the model on was accidentally used to train the model. There are more complex scenarios where you get leakage without actually showing the model the test examples. Where you have features that have future information in them that you won't have at actual inference time. So usually it ends up in overfitting, but is more about having information at training time that it shouldn't.
- dotnet00 2y agoI think a popular example of leakage would be that of a tank recognition AI that perfectly handles training/testing data but fails in real use, because all the tanks of one country happen to have a tree in the background, while those of the other do not, effectively leaking the image label and making the model look for a tree instead of the tank. Even if you trained less or used fewer parameters, it'd still go for the easiest route of trying to detect features of a tree. You'd have to change the training data.
- russfink 2y agoThese are two different definitions. Can someone please disambiguate?
- quantum_state 2y agoAI is a tool … a fool with a tool is still a fool … For natural sciences, there is no need to worry since nature would provide the ultimate check … for social “sciences”, it is entirely a different story.
- userbinator 2y agoPeople treating tools like they're infallible has been a problem since computers were invented, but IMHO the biggest difference with AI is how confident and convincing it can be in its output. Much like others here, I already have had to convince, very carefully, many otherwise-decently-intelligent people who believed ChatGPT was correct. Thus I think the biggest success of AI will be the arts, where imprecision is not fatal, and hallucinations turn into entertainment instead of "truths".
- antonvs 2y agoI think this misses something important. If it makes economic sense, corporations will figure out ways to integrate AI into their processes, even if it's imperfect. After all, companies are already built out of humans who are also often confidently wrong - but successful companies have ways to detect and mitigate that. In fact, that's one of the primary requirements for a company to survive, that it's able to build a functioning system out of imperfect components, particularly humans. You can see an example of this in the use of LLMs to generate code. In that case, there's a whole SDLC pipeline designed to detect errors: type systems, language compilers and runtimes, tests of various kinds, QA, user feedback, etc. We don't just trust confident software developers to produce correct code. Even a life-critical function like medical imaging - where imprecision can be fatal - can potentially benefit from this, where AI is used in conjunction with human review. It mainly requires development of some standards of practice - unlike with an average user blindly trusting the output of a model, radiologists would need training on how to use the models in question.
- bitwize 2y agoLLMs are basically Dissociated Press, but with deeper layers of statistics for a better function approximation than a simple Markov chain. It's really doing the same thing though: pick the next sequence of characters that best follows the foregoing characters. Not something I'd trust as a "source of truth". Maybe a neat idea generator. And some of the deep learning algorithms can identify patterns that humans might miss -- patterns that could reveal useful insight. But they're not doing the knowledge work.
- devjab 2y agoI would have thought scientists weren’t going to use these tools to do research considering they as a group are far more exposed to things like peer reviews and critical thinking than general society. What worries me the most about these AI solutions, however, is their usage in the public sector. They can certainly be useful helpers, like, they can scan images for cancer and if added to existing processes involving humans, often lead to enhanced results. They can’t replace any existing methods, however, as we learned here in Denmark a few years ago. Unfortunately that lesson hasn’t been learned across the public sector. I think medicine and healthcare learned it, but right now, we’re replacing actual human controls, audits and sometimes decision making with AI or an unwarranted trust in AI results. Which is going to lead to some really terrible results considering how bad things like LLMs often are at being lucky in even “common knowledge” situations. It’s further enhanced by how some of the work it’s tasked to do isn’t as black-and-white as writing code is. We use AI tools in our daily work, and they are ok, but as anyone who’s used them for programming probably knows by now, they aren’t exactly great at being lucky. Sometimes they’ll hallucinate solutions that simply do not exist. This is how they work, and as I said earlier, AIs can be great enhancers. They aren’t replacements though, and if we start treating them like they are, which is very tempting from a change-management and benefit-realisation perspective, we’re just going to get in trouble. This is unfortunately exactly what we’re doing, and why wouldn’t we? Most western public sectors have functioned on at least some form of new public management for two decades by now, sometimes longer. As a result the entire systemic culture is geared toward efficiency and cost reduction, even when it doesn’t really result in either efficiency and cost reduction on a broader perspective. Now, if scientists are on board. Then what hope does a public bureaucracy have?
- chomskyole 2y agoMaybe they should also call it "curve fitting" instead of "AI" so they don't need to call a "poor fit" a "hallucination"
- hollerith 2y agoIt's all very simple, eh?
- chomskyole 2y agoLook, it's a bit late here so I don't really have time to fully refute your sophisticated argument. But let me ask you this: if AI is not curve fitting, what is it then?
- deleted 2y ago[deleted]
- deleted 2y ago[deleted]
- hollerith 2y agoI'm objecting to the implication that if we start referring to it as curve fitting rather than AI, then thinking about it becomes easier and it becomes less likely that we will make a huge collective mistake in thinking about it. I'm not saying there aren't a few possible mistakes that do become less likely if we switch to "curve fitting, but I suspect that it does not matter much either way on the most serious mistakes.
- chomskyole 2y agoI think it would alter the entire safety discussion that was started. Let's say a company creates an automated system based on a curve fitting algorithm. Then things go wrong. Now it is quite easy to say the company is responsible for any damage and must pay for the rectification. When we say an AI is deployed and things go wrong, we have a sci-fi movie and responsibility is somehow magically moved away from the company that deployed the algorithm. To me it feels that "AI" as a term is a clever marketing term that companies will use to deflect responsibility. And I think it is one of the reasons why Open AI, Musk and others pushed this AI safety non-sense. The aim of calling it "curve fitting" or something similar would be to take the magic out of it so the broader public doesn't get confused. I think that's worthwhile.
- hulitu 2y ago> Scientists should use AI as a tool, not an oracle T in AI stands for tool.
