LLMs are solving MCAT, the bar test, SAT etc like they're nothing. At this point their performance is super human. However they'll often trip on super simple common sense questions, they'll struggle with creative thinking.

Is this literally proof that standard tests are not a good measure of intelligence?

Citation needed that LLMs are passing these tests like they’re nothing.

LLMs don’t have intelligence, they are sentence generators. Sometimes those sentences are correct, sometimes they’re gobbledygook.

For instance, they fabricate real-looking but nevertheless totally fake citations in research papers https://www.nature.com/articles/s41598-023-41032-5

To your point we already know standardized tests are biased and poor tools to measure intelligence. Partly that’s because they don’t actually measure intelligence- they often measure rote knowledge. We don’t need LLMs to make that determination, we already can.

Talked about this a few times over the last few weeks but here we go again...

I am teaching myself to write and had been using chatgpt for super basic grammar assistance. Seemed like an ideal thing, toss a sentence I was iffy about into it and ask it what it thought. After all I wasn't going to be asking it some college level shit. A few days ago I asked it about something I was questionable on. I honestly can't remember the details but it completely ignored the part of the sentence I wasn't sure about and told me something else was wrong. What it said was wrong was just....not wrong. The 'correction' it gave me was some shit a third grader would look at and say 'uhhhhh.....I'm gonna ask someone else now...'

[–] [email protected] 27 points 8 months ago

That's because LLMs aren't intelligent. They're just parrots that repeat what they've heard before. This stuff being sold as an "AI" with any "intelligence" is extremely misleading and causing people to think it's going to be able to do things it can't.

Case in point, you were using it and trusting it until it became very obvious it was wrong. How many people never get to that point? How much has it done wrong before then? Etc.

Standard tests don’t measure intelligence. They measure things like knowledge and skill. And ChatGPT is very knowledgeable and highly skilled.

IQ tests have the goal of measuring intelligence.

[–] [email protected] 29 points 8 months ago (1 children)

just a reminder that IQ tests may have the goal of measuring intelligence, but that says nothing of their precision and accuracy

[–] [email protected] 16 points 8 months ago

Exactly. I chose my words very carefully.

All standardized test is how well you prepared for that particular standardized test, doesn't matter if it is the SAT, MCAT, or Leetcode. You aren't suppose to think on the spot for these tests, you are suppose regurgitate everything you have rehearsed for weeks and months during the test.

And unthinking regurgitation is what LLMs do better than anything else.

[–] learningduck 7 points 8 months ago* (last edited 8 months ago)

I would argue that some code test questions can be solved spontaneously, but they are limited to easy to some early medium questions, or patterns that are common enough.

I guess this is more common in non FANG companies that don't have to filter out candidates just because of the sheer number alone.

[–] [email protected] 3 points 8 months ago

As someone that didn’t really have good coaching on the SAT, I 100% agree. I kinda fucked it up, but at 17, I wasn’t really used to studying for things outside of school and my parents didn’t get me into any study classes

For GRE though, I studied my ass off… got top 96 percentile scores.

Also went through the leetcode grind. Bombed the first job search I ever did and then later aced the hell out of it after studying really hard.

These tests are all about how diligently you studied and your study technique.

[–] [email protected] 41 points 8 months ago (2 children)

There has been plenty of proof that standardized testing doesn't work long before ChatGTP ever existed. Institutions will keep using them though because that's what they've always done and change is hard

[–] [email protected] 20 points 8 months ago

Long before. Even in 1930 the eugenics-motivated creator Carl Brigham recanted his original conclusions only years ago that had led to the development of the SAT, but by then the colleges had totally invested in a quick and easy way to score students, even if it was inaccurate. Change is hard, but I think the bigger influence here was money since it hadn't been around that long at that point.

[–] [email protected] 11 points 8 months ago (2 children)

Not disagreeing with you; how do you suggest a way for admissions to reliably compare applicants with each other? A 3.5 at one school can mean something completely different than a 3.5 at another school.

Something like the SAT is far from perfect, but it is a way one number that means the same thing across applicants.

[–] [email protected] 7 points 8 months ago

I think this is the point, because Harvard got rid of the SAT requirement, and then just brought it back.

It’s a really terrible measure .

But it is an equal measure, despite what it measuring moderately meaningless.

I don’t think we have a better answer yet, because everything else lacks any sort of comparable equivalency .

And I say this as an ADHD sufferer who is at a huge disadvantage on standardised testing

When I was at uni lecturers would often state that exams were thr worst measure of grasping the subject material but its all we have at the moment.

I saw this my self with some of my class mates testing very well but when discussing or problem solving outside of the class there was nothing there.

I think llms fall into this category but with way better recall.

[–] [email protected] 7 points 8 months ago (1 children)

I had a lot of professors who put most of the grade weight on large projects. It made for a very heavy workload, but projects/ papers give a much better picture of how capable someone is of not only reciting knowledge, but also applying it.

I think it highlights how a lot of these exams are just about the amount of information one can memorize.

Standardized tests were always a poor measure of comprehensive intelligence.

But this idea that "LLMs aren't intelligent" popular on Lemmy is based on what seems to be a misinformed understanding of LLMs.

At this point there's been multiple replications of the findings that transformers build world models abstracted from the training data and aren't just relying on surface statistics.

The free version of ChatGPT (what I'm guessing most people have direct experience with) is several years old tech that is (and always has been) pretty dumb. But something like Claude 3 Opus is very advanced at critical thinking compared to GPT-3.5.

A lot of word problem examples that models 'fail' are evaluating the wrong thing. When you give a LLM a variation of a classic word problem, the frequency of the normal form biases the answer back towards it unless you take measures to break the token similarities. If you do that though, most modern models actually do get the variation completely correct.

So for example, if you ask it to get a vegetarian wolf, a carnivorous goat, and a cabbage across a river, even asking with standard prompt techniques it will mess up. But if you ask it to get a vegetarian 🐺, a carnivorous 🐐 and a 🥬 across, it will get it correct.

GPT-3.5 will always fail it, but GPT-4 and more advanced will get it correct. And recently I've started seeing models get it correct even without the variation and trip up less with variations.

The field is moving rapidly and much of what was true about LLMs a few years ago with GPT-3 is no longer true with modern models.

[–] [email protected] 9 points 8 months ago* (last edited 8 months ago)

I don't know... I've been using ChatGPT4. I use it only where the knowledge it outputs is not important. It's good when I need help with language related things, as more of a writing assistant. Creative stuff is also OK, sometimes even impressive.

With facts? On moderately complicated topics? I'd say it gets something subtly wrong about 80% of the time, and very obviously wrong 20%. The latter isn't the problem.

I don't understand where the "intelligent" part would even come in. Sure, it requires a fair level of intelligence to understand and generate human language responses. But, to me, all I've seen fits: generate responses that seem plausible as responses to the input.

If intelligence requires some deeper understanding of the world, and the facts and relationships between them, then I don't see it. It's just a coincidence when it looks like it happened. It's impressive how often that is, but it's still all it is.

[–] [email protected] 9 points 8 months ago

LLMs have a good time with standardized tests like SAT precisely because they're standardized, i.e. there's enough information on the internet for them to parrot on them

Try something more complex and free-form and where a human might have to work a little more to break it down into actual little subtasks with their intelligence - and then solve it, LLMs in the best case scenario will just say they don't know how to do it, and in the worst case scenario they'll hallucinate some actual bullshit.

[–] [email protected] 8 points 8 months ago

Ask an LLM to explain a joke. It often won't understand why a joke is funny, but that won't stop it from trying to give you an explanation.

[–] [email protected] 7 points 8 months ago

Those tests are not for intelligence. They're testing whether you've done the pre-requisite work and acquired the skills necessary to continue advancing towards your desired career.

Wouldn't want a lawyer that didn't know anything about how the law works, after all, maybe they just cheated through their classes or something.

[–] [email protected] 7 points 8 months ago

Eh, yes and no. It might help illustrate the limitations of testing for some people, but it's not really telling us anything new about them. It is meant to cheaply provide an indication of how a student is fairing and has never been considered by anyone serious as some kind of comprehensive measure of intelligence. Their flaws have been known for a long time.

[–] [email protected] 7 points 8 months ago* (last edited 8 months ago)

We use standardized tests because they’re cheap pieces of paper we can print out by the thousands and give out to a schoolfull of children and get an approximation of their relative intelligence among a limited range of types of intelligence. If we wanted an actual reliable measure of each kid’s intelligence type they’d get one-on-one attention and go through a range of tests, but that would cost too much (in time & money), so we just approximate with the cheap paper thing instead. Probably we could develop better tests that accounted for more kinds of intelligence, but I’m guessing those other types of intelligence aren’t as useful to capitalism, so we ignore them.

[–] [email protected] 6 points 8 months ago

Everyone knew this.

Obviously 1:1 mentoring, optional cohort/Custom grouping, experiential, self paced, custom versioned assignment learning is best but that's simply not practical for a massive system.

[–] [email protected] 5 points 8 months ago (1 children)

Intelligence cannot be measured. It's a reification fallacy. Inelegance is colloquial and subjective.

If I told you that I had an instrument that could objectively measure beauty, you'd see the problem right away.

[–] [email protected] 18 points 8 months ago* (last edited 8 months ago) (5 children)

But intelligence is the capacity to solve problems. If you can solve problems quickly, you are by definition intelligent.

the ability to apply knowledge to manipulate one's environment or to think abstractly as measured by objective criteria (such as tests)

https://www.merriam-webster.com/dictionary/intelligence

It can be measured by objective tests. It's not subjective like beauty or humor.

The problem with AI doing these tests is that it has seen and memorized all the previous questions and answers. Many of the tests mentioned are not tests of reasoning, but recall: the bar exam, for example.

If any random person studied every previous question and answer, they would do well too. No one would be amazed that an answer key knew all the answers.

[–] [email protected] 7 points 8 months ago (1 children)

But intelligence is the capacity to solve problems. If you can solve problems quickly, you are by definition intelligent

To solve any problems? Because when I run a computer simulation from a random initial state, that's technically the computer solving a problem it's never seen before, and it is trillions of times faster than me. Does that mean the computer is trillions of times more intelligent than me?

the ability to apply knowledge to manipulate one's environment or to think abstractly as measured by objective criteria (such as tests)

If we built a true super-genius AI but never let it leave a small container, is it not intelligent because WE never let it manipulate its environment? And regarding the tests in the Merriam Webster definition, I suspect it's talking about "IQ tests", which in practice are known to be at least partially not objective. Just as an example, it's known that you can study for and improve your score on an IQ test. How does studying for a test increase your "ability to apply knowledge"? I can think of some potential pathways, but we're basically back to it not being clearly defined.

In essence, what I'm trying to say is that even though we can write down some definition for "intelligence", it's still not a concept that even humans have a fantastic understanding of, even for other humans. When we try to think of types of non-human intelligence, our current models for intelligence fall apart even more. Not that I think current LLMs are actually "intelligent" by however you would define the term.

[–] [email protected] 5 points 8 months ago

Does that mean the computer is trillions of times more intelligent than me?

And in addition, is an encyclopedia intelligent because it holds many answers?

[–] [email protected] 2 points 8 months ago

This is a semantic argument.

Have you never felt smarter or dumber depending on the situation? If so, did your ability to think abstractly, apply knowledge, or manipulate your environment change? Intelligence is subjective (and colloquial) like beauty and humor.

such tests are not standardized tests of intelligence, they are standardized tests of specific-competencies.

Thomas Armstrong's got a book "7 Kinds of Smart, revised", on 9 intelligences ( he kept the same title, but added 2 more ).

Social/relational intelligence was not included in IQ because it is one that girls have, but us guys tend to not have, so the men who devised IQ .. just never considered it to have any validity/significance.

Just as it is much easier to make a ML that can operate a commuter-train fuel-efficiently, than it is to get a human, with general function, to compete at that super-specialized task, each specialized-competency-test is going to become owned by some AI.

Full-self-driving being the possible exception, simply because there are waaaaay too many variables, & general competence seems to be required for that ( people deliberately driving into AI-managed vehicles, people throwing footballs at AI-managed vehicles, etc, it's lunacy to think that AI's going to get that kind of nonsense perfect.

I'd settle for 25% better-than-us. )

Just because an AI can do aviation-navigation more-perfectly than I can, doesn't mean that the test should be taken off potential-pilots, though:

Full-electrical-system-failures do happen in aviation.

Carrington-event level of jamming is possible, in-flight.


  • Intelligence is "climbing the ladder efficiently".

  • Wisdom is knowing when you're climbing the wrong ladder, & figuring-out how to discover which ladder you're supposed to be climbing.

Would you remove competence-at-soccer tests for pro sports-teams?

"Oh, James Windermere's an excellent athlete to add to our soccer-club! Look at his triathelon ratings!"..

.. "but he doesn't even understand soccer??"

.. "he doesn't need to: we got rid of that requirement, because AI got better than humans, so we don't need it anymore".

idiotic, right?

It doesn't matter if an AI is better than a human at a particular competency:

if a kind-of-work requires that competency, then test the human for it.

[–] [email protected] 4 points 8 months ago

Tests built for humans are not tests built for machines.

[–] elint 4 points 8 months ago

No. It may be proof that standardized tests are not useful measures of LLM intelligence, but human brains operate differently from LLMs, so these tests may still be very useful measures of human intelligence.

[–] [email protected] 4 points 8 months ago* (last edited 8 months ago)

I don't think any of those tests ever claimed to be a general intelligence test, they're specific knowledge tests. Books also contain a ton of specific knowledge but books are not intelligent.

[–] [email protected] 3 points 8 months ago (1 children)

No. It’s the opposite in fact. It shows that ChatGPT is not very intelligent. Just very well-read.

[–] [email protected] 3 points 8 months ago

It shows that it's well-read but not that it isn't intelligent. It says relatively little about its intelligence (although the tests do require some).

[–] [email protected] 2 points 8 months ago

Intelligence is not the same as knowledge.

[–] [email protected] 2 points 8 months ago

We already knew that intelligence is a complex and multifaceted property, and that being very intelligent and being very good at taking tests are two distinct (albeit loosely correlated) skills. It's just a too convenient measurement despite it's many flaws.

This is only news if you're an ignorant techbro who doesn't pay attention to any other field except computer programming.
