IQ is a dismal measure of intelligence (2019) (supermemo.guru)

The article doesn't appear to suggest a viable substitute for IQ. It concludes that we should "[measure] what an intellect can accomplish in a lifetime," but this isn't really practical.

IQ is not a perfect measure of intelligence, but I think it's better than no measure of intelligence.


Nobel winner James Heckman did a lot of work on this [1].

The takeaway is that IQ doesn't matter as much as other attributes (character, learned skills, etc.) in life outcomes.

HN style crows way overvalue IQ style skills when intelligence has multiple dimensions, many of which matter more than IQ.

IQ is effectively just a measure of test-taking skills. That's useful in some areas, but you could see someone like Gengis Khan or Nikola Tesla be incredibly intelligent and a poor test taker.

But IQ wasn't invented to predict "life outcome", it was invented to find kid's academic potential.

I'm still waiting for somebody to show me a prolific Math Phd with below average IQ. The only counter example I've heard people use it Feynman whose IQ was "only" 125 putting him smarter than "only" 95% of the population.

It rubs me the wrong way when Hawkins says stuff like "IQ is for losers" but then boasts how his physics undergrad degree was so easy for him he was just bored out of his mind (it sure wasn't easy for me). It's the intelligence equivalent of a billionaire saying you just need to work hard to get there, as if that was ever gonna make a difference if you're an Amazon factory worker.


I've never taken an IQ test, nor will I ever take one.

Am I smarter than the average person? undoubtedly.

But if my IQ is high then I fear I'll avoid doing useful things because they're beneath me. And if my IQ is not high, I fear I'll avoid doing things because they're above me.

There is nothing useful that can come out of knowing your IQ, and as others have said, there's other things that are so much more important. Smart people are unusually good at deluding themselves, for example. They get so used to being right they start to believe if they can rationalize it, it's obviously true and anyone who disagrees isn't as smart.

Having said that, I once made a girl angry in college because I asked the professor if grad school will actually be challenging because undergrad math for me was ridiculously easy.

I think the best way to describe IQ is that it defines your potential (w/i a margin of error), but it's everything else that determines how effectively you use that IQ.

A child with down syndrome will never win a nobel no matter how much they want to or how much effort they put into it. But having an IQ of 160+ will never guarantee you don't end up homeless in a ditch.


I have a dream : I would like to do research and do breakthroughs in the field.

Knowing my IQ would let me know if that's reasonable and if I have any kind of shot at it. I know I'm smarter than average, but am I smart enough to be a top scientist? If i'm too stupid to attain my dream and I went for a phd, I would just be wasting my time, my life, my earnings for a dead end. It would be like dedicating your whole life to being a pro basket-ball player while having no shot because you're 5'10" (taller than average, but not tall enough).


I read a book years ago (forget the name or the author) about an alien species that came to earth and claimed they were in a war and were looking for the single best specimen from each species (1 per planet).

The one they settled on was a man in a wheelchair. Through technology they fixed all his ills.

They then put him on a ship with all the others and he was immediately attacked. It turned out there was a hierarchy and it had to do with physical violence. They wouldn't let you die and all injuries would be healed so it was safe, if painful, to do.

Throughout the book you learn the aliens that came to earth are very logical, by the book, run the numbers.

So this human realizes this and realizes he wants more control so he starts working his way thorugh the hierarchy. he gets to the 2nd highest rank, but cannot beat the highest rank alien, but he keeps trying ... and trying ... and trying. Finally the highest rank alien asks him why, he explains, the highest rank alien steps to the side and gives him the highest rank.

Later on in the story the aliens fighting the war decided the statistical odds weren't there and they were going to let all the worlds where they had gathered specimens be overrun. The crew on this ship with the humans rejected it, overtook the ship, and went to fight on their own. They did well enough on their own to tip the numbers just enough that the aliens fighting the war chose to re-engage.

----

The point here is this. You cannot live life by the numbers, you'll be wrong because it doesn't take into account risk. I know you, and many others, will argue against that, but it's true.

Here's an example: Statistically speaking, you should never cross a busy highway. If your child is on the other side of that highway and in danger, you will 100% do it. Statistics can never take into account the reasons for the risk or the worthiness of the risk.

----

The numbers are lying to you. Yes, there's a line at which you'll never be able to do better, but once you're past that line there's a large margin of error. Don't live your life afraid of that margin of error, embrace it.


Sorry, but I don't find a science fiction book to be an inspiring argument.

Find me a below average height person who made it at the NBA or somebody, anybody, with a below average IQ who got a science Nobel prize and you'll have my attention. But if you have to rely on a pure fantasy novel to find a counter-example, it doesn't give me any confidence in your theory.


> Sorry, but I don't think you can learn anything from allegories, they're not "real life".

there, fixed that for you.

As for the rest ...

https://en.wikipedia.org/wiki/List_of_shortest_players_in_Na...

The shortest NBA player was 5'3" and played until 2001.

Isaiah Thomas is the shortest player to play in an all-star game at 5'9".

---

But hey, good luck, I'm sure you're smarter than the rest of us and you'll do just fine without allegories.


You've caught me, I'm an allegory hater. Thanks about that NBA player list. Truly inspiring somebody who's 5"3' could play in the NBA.


It was invented as a clinical test of retardation, and the only correlation with IQ and objective independent measures of performance is in the region of very low scores.

Note, that when carear-IQ correlations are brought up it is universally in those populations subject to an IQ test filter who are then shown to correlate with IQ scores (ie., those who take, eg., MCAT, LSAT, ...) --- which, if it isnt clear, is circular.

Average and above IQ shows no correlation whatsoever with, eg., wealth.


IQ is a fair predictor of achievement in life, though. But there are other predictors too, such as parents' socio-economic status, or geographical location. We wouldn't claim these things measure intelligence, though. IQ is a proxy for intelligence, but one with great shortcomings. Unfortunately, there's no agreed upon definition of intelligence, let alone an operalization, and a way of measuring it. So IQ keeps being used.


> Unfortunately, there's no agreed upon definition of intelligence, let alone an operalization, and a way of measuring it. So IQ keeps being used.

Uhuh.... so this line it's crazy, right?

It's really strange you concede that we have no theory and hence no way of verifying whether an IQ score is a valid and reliable measure of the thing we have no theory of... and yet, you say it is a "proxy for intelligence"

The entire edifice of research which makes these claims is a product of a pseudoscientific use of statistics by amateur statisticians. The vast majority of the results you think exist in the literature are frauds, and often egregious ones at that.

A human being is one of the most complex systems known to exist in nature, and the frauds in psychometrics are very far away from being up to the task of studying them. The greatest minds in applied sciences, matehmatics and statistics would largely throw up their hands at the job of measuring "intelligence" --- that some fools havent, is no good thing.


We all "sort of" recognize intelligence, but it stops there.

> The entire edifice of research which makes these claims is a product of a pseudoscientific use of statistics by amateur statisticians.

That's bollocks. It's just a topic that's too complex. Unfortunately, everybody likes it and draws conclusions from it. Even the HR department. If you would say we should ignore IQ measurements in society, I would agree. But it's not pseudo-scientific use of statistics. Nor all done by amateurs. It might even be more scientific than string theory or dark matter.


Alas, it is. It's severely pseudoscientific.

None have PhDs in statistics. They're all people who got into psychology and were given GUIs by the maths department. Their papers are a symptom of what happens when you press the "ANONVA" button and print the results.

The entire field is an egregious testament to pseudo-intellectual pseudoscience. It's shocking.

There's nothing there. It's unfathomably bad.


The statisticians I knew were only too happy to go along with some ANOVA. They're usually consulted at the start of the study, but rarely co-author.

A lot of psychology is bad research. There's a reason there's a reproduction crisis. Statisticians are to blame for that, too. They've been teaching and using NHST, even though all arguments point away from it.

But statisticians can't fix a bad design, because they rarely know the factors involved, and they can't fix errors in the methods, because they've got no idea about the subject matter. The statistician in your argument comes across as some kind of totem.

> There's nothing there.

There's something there, but since we don't know what, it's best to take it with a grain of salt. However, if even the bloody HR department looks at IQ scores, it gets a lot of attention. And one explanation is that it predicts better than nothing. If you have to choose between two candidates, and one has an IQ of 80 and the other of 120, you know who (on average) who fits best.


Neither "have" an IQ of anything. They neither "have" a star-sign.

A score of 80 suggests a possible clinical issue with mental retardation. Few such people apply to roles who compete with people at average or above scores.

What is much more the case is people 95-145 "competing" with each other based, effectively, on what star sign they have.


If IQ didn't matter above 95 then we would expect most STEM professionals to have about 100 IQ since that is the biggest bump on the curve, but that is very far from the case.

The test probably breaks down at some level since it is hard to test higher intelligence, but it seems to me like it is still valid below about 120 IQ.


We also don't have an objective measure of "horniness", yet we all know it both exists and that we must make decisions based upon it (either ours or others).

Something having an objective measure or not does not invalidate it.


I think we've very good evidence against IQ being a measure of intelligence.

But in any case, what we're talking about is the meter-ruler called "IQ" and its use by the most batshit HRish elements of soceity, and the most pseudo-scientific elements of psychology.

In a world where major employers are using IQ to guide their hiring practices, we're not talking about a quiz on the back of cosmo.

We're talking about a world where business (, uni,...) has outsourced its obligations to fairly consider the merits of individuals to the cult of psychometricians extremely happy to provide astrological justifications for ruining people's lives.

An entire medical establishment has been created by the IQ test, which exists across (at least the west) as a filter on entrants. What strange, bizarre, and often poorly sutied creatures have found themsleves in positions within this establishment?

When one looks around at the society the IQ test has created, one should be aghast. Why, so often, are nurses better than doctors? (etc. etc.)


This is akin to arguing height isn't useful because the NBA makes judgements based upon it.

What the evidence says is that IQ isn't the only factor, just as height isn't the only factor for NBA players. But just like height, IQ makes things a lot easier.


> IQ is effectively just a measure of test-taking skills.

Omg, no.

Good test taking skills will help someone score close to their theoretical maximum, but you can’t just train someone in test-taking skills and expect them to score at the top of the scale.

I’ve trained people on test-taking skills to great effect, but there is a limit (often significant) on how much these skills can improve a score.


"test-taking" is too generic. Puzzle-solving would be more accurate. IQ doesn't do much for test that just require to remember a lot of stuff.


To me this is like saying that if you were lost in Boston and someone gave you a map of Chicago that it's better than nothing.


Well we do know that [all North American cities] look the same so to that extent you can use a map from a different city to find your way.

[all North American cities](https://www.reddit.com/r/MapPorn/comments/ym6ms5/a_map_of_ev...)


It's more like saying "it's better if someone gave you a hand-drawn map of Boston, instead of no map at all".


Why do we really need a measure of intelligence? What does this grant us aside from giving people yet another cudgel with which to lord over others, and another way for unfortunate people to feel bad about themselves?

When/how is IQ ever used for good? Everyone I have ever talked to about it who talks about others' IQ intends to use those people for their own selfish purposes. And people I've talked to who talk about their own IQ only ever use it to brag, boast, or otherwise elevate themselves. Neither of these are behaviors that should be encouraged.


Well that's easy: to change education for people based on their abilities. Any specific class can only be educated to the lowest level everyone in the class will support. So you split up classes by IQ, you don't even give more opportunities to the "high-IQ" class. You just split them up. Nothing more.

Generally this is not based on actual IQ test results, but on teachers impressions. And they keep "secret" which is the high IQ class. And if a kid is really motivated to be in the better class, change the kid to the other class (and vice-versa) if at all possible.

Of course this worked better with 15 kids-per-class than with the current 40 kids-per-class education system.

This is doing a lot of good, and has been for decades. Essentially it results in a smarter and more capable society, because people can be educated much closer to the limit of their abilities.


Changing culture to stop seeing intelligence as some unchangeable fixed thing is probably better than having a bad measure of "intelligence".


Even IQ itself was meant as a way to identify what supports people need to keep up and negate the difference.


Right, but aside from academics, what is the use for the number. Like, sure, it will maybe tell you that person A is better than person B at solving what essentially are logic puzzles, but that's at best tangentially related to most things, even in "intellectual" jobs it's a mix of knowledge, creativity and ability to see correlation plus almost always some social skills too.


No, it is worst than no measure of intelligence. It gives a false impression of the truth that can hurt the person or people involved. IQ is often used in racist terms, since certain populations in the world do not have the cultural background to pass this arbitary test


Aren't IQ tests supposed to be made culturally/language independent tho ? What would be "cultural" thing on IQ test ? The ones I saw never really had anything aside base-10 numbers. Do you have any examples ?


The most famous example was of black kids who never seen a ruby in their lives in the 50s. But Ruby the name was quite popular. So they got that question wrong. But it is normally used to denigrate Africans who have even less exposure to European norms than African Americans. Despite the genetic diversity of Africans being a lot higher than Europeans, they are often thrown into the same batch of "IQ deficient" groups. None of this is actually scientifically sound.


There are many different types of IQ tests, with different types of questions. Some just use shapes/patterns.


I'd disagree. The use of bogus psychometrics is not socially neutral. It's used to filter applications to university courses, jobs, and so on. They make a systematically, imv disasterous, effect on the lives of everyone they come into contact with.

IQ tests are only a clincally valid test of extreme mental deficits. They do not correlate with objective measures of above-average performance, and have created a "metrical culture" with severe unethical concequences.


"IQ is part of a large “nexus” of positively correlated societal outcomes. IQ correlates positively with family income, socioeconomic status, school and occupational performance, military training assignments, law-abidingness, healthful habits, illness, and morality. In contrast, IQ is negatively correlated with welfare, psychopathology, crime, inattentiveness, boredom, delinquency, and poverty."


Indeed, all basically false.

Fit a straight line, find a straight line.

Where IQ scores correlate, it's at the very-low-score end. It doesnt correlate with independent objective performance measures at average-and-above.

The people writing those papers are psychologists, not statisticians, and often the most poorly trained. Most of it is either circular pseudoscience or unreporducible. Indeed, for much of the IQ literature to be "unreporducible" would be a great credit, since it would mean it had a testable thesis -- which, largely, it never does.

The beginning and end of IQ research is, largely, just that straight-line rulers can draw straight lines in any dataset you put them against.


That's more a rant than useful information.

However, it's a politically popular position in some circles in recent years.

Compare Wikipedia in 2015 [1] with Wikipedia today [2].

Personally, via Peterson, I read a lot of the IQ literature and Peterson's arguments around it. I became reasonably convinced of his major claims (namely that IQ is a valid measure of intelligence, that heritability is a valid measure of genetic determination, and that IQ is largely heritable). (Incidentally, all these claims are profoudnly false).

Subsequently, I watched a long-form breakdown of IQ and my doubts increased. I then "clicked" IQ into place: for most of my adult life ive been complaining about fMRI, pharam, (AI), etc. -- ie., medical misuse of stats --- and somehow Peterson had lulled me into a false sense of security.

Taleb's article was the nail in the coffin, and I read around the references associated with it. I now place psychometrics firmly in that category of pseudoscience which is "absue of statistics by idiots in lab coats with GUIs".

I expect the culture to be following along with me, if at a long long distance. I think in 2022 "the informed elite" are roughly absorbing the obvious issues with AI, Psychology, etc. and that tradition of statisitcal BS which was clear at least a decade ago.

My "pro-IQ" scepticism was initially agaist people worried about racism, etc. It's very lullying for a sceptic to be confronted by people who dont care about reality that muhc. But this is a trap. IQ is actually BS, and its a shame that the people often most against it are also often very poorly informed.

To address IQ research head-on is a little like like addressing old-testament theological scholarship. The level of understanding of both the field, statistics and the philosophy of science required is very high.

It's a field which florishes, as often with theology, from extremely complex arguments with absolutely insane hidden premesies.



The more one reads about IQ from serious statisticians, the worse the story of modern psychology becomes.

There is a "pseudoscientific tradition" of statistics wherein one assumes systems are linear, one uses only linear models, and wherein one reports only associations on non-experimental conditions. This tradition was invented by psychologists, for psychology, and it's had horrific ethical consequences. I'd go so far to say that any system or results obtained by this method should now, a priori, be regarded as pseudoscience and should require a massive cross-disciplinary consensus to be regarded otherwise.


It's hardly "scientific evidence", but my personal assessments of "how intelligent someone is" appear to correlate quite well into various "IQ bands" if a score is revealed at some point. That may be a coincidence, or they may be dependent upon some other unknown factor(s), but it does work out in practice.

People who criticize IQ scores as a proxy for intelligence should publish their own IQ score, no? If the author did so, I missed it, which is certainly possible. The not-intentionally-snarky point is that perhaps the author is not "smart enough" to assess this reliably.


Are you sure you're not confusing cause and effect? Like maybe your view of "intelligence" is limited to the definition used by IQ tests. That would be kind of unfortunate because it selects for a certain type of test taking ability, mostly related to logic puzzles and spatial manipulation and vocabulary. Those skills might be useful in academic and some professional contexts, but they don't really benchmark the entirety of human potential.

Human intellect has the capacity for creativity, empathy, wisdom, self awareness, diplomacy, etc., and those aren't as easily measured on an IQ quiz.

Just my 2c as someone who's not professionally trained to apply IQ tests but have studied them as a side interest, and scored highly on them (probably like many others here). It's just one biased facet of our minds, and we shouldn't give it undue weight or rule people out because their minds work differently.


I did notice it's pretty easy to be perceived intelligent if you just happen to have a bunch of knowledge in the subject you talk about, and shut up in subjects you have no idea


>People who criticize IQ scores as a proxy for intelligence should publish their own IQ score, no? If the author did so, I missed it, which is certainly possible. The not-intentionally-snarky point is that perhaps the author is not "smart enough" to assess this reliably.

From the article:

>I did try an IQ test in the past a few times. [..] I will not disclose the results, because I do not want this text to be skewed by a number I am criticizing. If the number was low, skeptics would say I am not smart enough to appreciate the value of IQ or that my claim is just sour grapes.


Okay, I'll bite.

IQ scores are utterly *worthless* as a measure of intelligence because they only measure one's ability to solve a small set of carefully-chosen puzzles under carefully-controlled conditions. They cannot possibly measure anything realistic about intelligence.

Since you want people who criticise IQ scores to publish theirs, I'll tell you mine. Measured at various points across my education and out of five or six scores, they range from 72 to 160. They can't all possibly be right.


Are we talking actual vetted IQ tests or some random webpage/gazette offering "IQ test" ? From what I remember "proper" ones generally don't have that much variance per person


Yes, actual proper IQ tests, intended to find out some parameter or another of my education.


You need to know percentile, not score.


You're never going to get much agreement on IQ as long as a certain type of strong egalitarianism is the prevailing outlook on the world, because the consequences of IQ being important tears apart virtually everything about that.

If IQ actually is reasonably important in some capacity, then it indicates that humans are not fungible and almost everybody would be forced to rewrite all of reality in their heads.


Intelligence itself is not a perfect proxy for effectiveness, which is what people assume IQ eventually implies


> IQ is remotely relevant to actual intelligence

> IQ is popularly perceived as determined by the genes and unchangeable

> IQ tests have a negative effect on test takers

> IQ is often used in "scientific" racism to promote pseudoscientific social theories

1. They say IQ doesn't measure intelligence because according to them "Intelligence is the ability to solve problems". Well IQ at least claims to do that with its with its fluid intelligence component. Maybe creativity is independent of IQ, and also corresponds to better problem solving skills, but that doesn't change the fact IQ is still a predictor of problem solving skill.

2. If you can prove IQ can be boosted, that would be revolutionary. There's the n-back that improves IQ according to some studies, but that's highly controversial. But in any case, I don't see how not being able to change it makes it a bad measure. Me not being able to make myself taller doesn't make height a bad measure.

3. People not handling well knowing their intelligence doesn't have anything to do whatsoever with IQ being a good or bad measure of intelligence.

4. Again, people using metrics to be racist is an argument against measuring intelligence, not against IQ itself. You could make the same argument about literally any other system measuring intelligence.

A point I find interesting is "school improves IQ". What if the reason we can't seemingly improve people's IQ was because the school system already brought them to their full IQ potential? Maybe when we're trying to increase people intelligence, because we're testing on people already at school, it's like conducting studies on how to get muscular on people who are already maxed out gym bros. It's gonna be very hard to get them more muscular/intelligent if they're already reached max allowed by their body through intense daily workout/schooling.


> 4. Again, people using metrics to be racist is an argument against measuring intelligence, not against IQ itself. You could make the same argument about literally any other system measuring intelligence.

Yeah, the real backlash against IQ is against the implied policy that people think ought to be implemented if IQ is real and determined genetically, as they believe that intelligence is related to moral worth, which raises the question of "what do we do with the worse people if we have a tool that can determine who is a better or worse human."

It's a complex mixup of Equity vs Equality.


> A point I find interesting is "school improves IQ". What if the reason we can't seemingly improve people's IQ was because the school system already brought them to their full IQ potential?

The hell kinda schools do they have around you? I promise you no school I ever attended even tried to do that. Anyone who had potential had to skirt around the school system.


I don't think your statement is disagreeing with his? Your school system elevated the students to the system's IQ upper bound. A different school system or style of education would have a different upper bound.


My argument is that the system is good enough to get the kids to their biological upper bound. Otherwise, we would be able to increase their IQ further through other means, but it seems we just can't.

I don't think the school system is necessarily efficient at it, but kids do spend an insane amount of time in school. I imagine people would reach their athletic upper bound too if they spent 8 hours a day in the gym from the age of 5 to the age of 18.


if you go back to the original goal of IQ tests, it was the measurement of learning progress and it's log tied to age of those under test.


It's sort of like getting a computer's performance.

All sorts of things goes into a measure.

Central processing speed, memory, memory access speed, cache size, software optimization and cache build up.

I think some people really WANT IQ to be only about central processing speed, but since that's not measurable we're trying to tease out what it is from the end performance metric. But really everything is important to intelligence, and something like software optimization and cache build up is really just education.

IQ measures things that are useful to other people when thinking about a person's as-is work-value, but is fundamentally flawed and useless when applied to a person's potential value or moral value.

But since the former is true it will continue to be a thing that people care about.


There is zero research to show IQ tests count as valid and reliable measures of anything associated with intelligence.

Your hypothesis as to what properties minds have, what those properties give rise to, and how IQ tests count as measures *has no scientific backing*. This description of IQ tests is, imv, an extremely unlikely account.

If you want to show IQ scores are measures of these properties, please provide (1) a theory of the mind in which these properties appear as experimental variables; (2) experiments in which these variables are controllable; and (3) evidence that IQ correlates with the expected controlled outcomes.

Note, the above has never been done. Making the assertion that IQ measures intelligence circular. It is simply, asserted.


> There is zero research to show IQ tests count as valid and reliable measures of anything associated with intelligence.

It is the opposite, IQ correlates with basically every measure and score people have came up with that they think could represent intelligence in some way. This concept is called G.


IQ is a dismal measure, yet it is the best predictor we have for a variety of operationalized constructs. Delete the soft sciences entirely if IQ, of all things, is not good enough for you.


There are two kinds of people in the world - people who believe IQ tests are a useful measure of anything, and intelligent people.


That doesn't make sense. Why there wouldn't be any dumb people that don't believe in IQ tests ?

Not believing in IQ tests (or really in any particular one thing) doesn't make someone intelligent.


"The only real test of intelligence is if you get what you want out of life." - Naval

I've come to agree with this assessment.


  Calvin: If you could have anything in the world right now. What would it be?
  Hobbes: Hmmm.
  Calvin: Anything at all! Whatever you want!
  Hobbes: A sandwich.
  Calvin: A sandwich?!? What kind of stupid wish is that?! Talk about a failure of imagination! I'd ask for a trillion billion dollars, my own space shuttle, and a private continent! 
  Hobbes: I got my wish.


Well I’m a fucking idiot then


It’s a dismally used measure of intelligence. But the validated IQ tests are pretty good at doing what they claim to do.

IQ tests have their place, but they are grossly and frequently used inappropriately, imho.

Note that actual psychology researchers like Howard Gardner and Robert Sternberg (and many others) have written quite a bit about various aspects of intelligence that the author alludes to. IQ is just one fairly narrow component of intelligence, and I don’t think that this point is debated much by modern researchers.

Let’s take the author’s arguments point by point:

> Problems with IQ

Summary: People use IQ scores in ways that are not appropriate for the measure. Boohoo.

This isn’t a problem with the test, it’s a problem with how the results are used.

> Intelligence cannot be separated from knowledge

IQ test creators acknowledge this, and they try to abstract out knowledge as much as possible. It’s not perfect, but it’s as close as they can get (especially for examinees in “the West”).

The author goes on to complain at length about “the injurious environment we push our kids into”, but this seems to be a different issue.

> IQ is no measure of intelligence

The author starts with “Intelligence is the ability to solve problems”. I would say that it’s the estimate of the capacity to solve problems. As the author mentions, other things come into play with regards to solving real-world problems. IQ tests don’t measure this and don’t claim to.

Interestingly, the author says “IQ tests might be as well replaced with tests of how fast people can count nickels”, and I think that this may not be as bad of a proxy for IQ as he thinks. The problem with nickels specifically is that some people may have done it before and/or may have been taught shortcuts. But if you give a test in which people have to count a variety of things of various shapes, sizes, values, etc. while on a timer, I’m guessing that the results would correlate fairly strongly with IQ.

> IQ is unreliable

Ah, totally agree, but I don’t think that it invalidates the test. This is a theme that I will come back to.

Any single IQ score should be seen as the minimum IQ for that person. There is a theoretical maximum (at least imho) for each examinee that is not always reached. There are so many things that cause people to score below this theoretical maximum, but very few things other than incredibly lucky guessing that will cause them to score above their theoretical maximum (and even this is eliminated when you factor in the confidence interval of a given result).

> Intelligence can be boosted

The theoretical maximum cannot be boosted. All one can do is improve the chances that they score as close to their theoretical maximum as possible (e.g., by getting good sleep, eating well, etc.).

> The psychological harm of IQ

Yes, if people misuse the score in ways that it was not intended (and many do), then it can cause psychological harm.

Any tool can be used in harmful ways, so I don’t think that this is news, and it certainly doesn’t invalidate the test.

> IQ myth

This section is just a weird diatribe of the author. He basically says that IQ doesn’t measure what he wants it to measure. As mentioned in my intro, psych researchers have explored the topic of intelligence writ large quite deeply.

> Child's IQ

Yeah. “Mental age” is an approximation. It’s not a bad one, but it is also misused. If people would just use it as a “directionally correct” measure, then it becomes more functional.

> Schools improve IQ

Same as above. School helps people score closer to their theoretical maximum. It doesn’t improve their theoretical maximum.

> IQ bloopers

Ugh. The author talks about IQ tests that have probably not been validated (at least not recently), and issues with not measuring the theoretical maximum.

Every standardized test used widely enough over time will have these “bloopers”. Every. Single. One.

> New forms of intelligence

Cool story. Arguably not intelligence. Definitely not the part of intelligence that IQ tests claim to measure.

> White supremacy

Very true.

Fwiw, it’s not just white people who think they are superior in terms of intelligence.

I have lived in some countries in which people have told me to my face about how much dumber on average white people are than [their race], using some sort of test score (typically a crude IQ proxy) as evidence. Of course, I’m the exception as a white person according to them, so I get a pass.

This is just another case of people misusing test scores. It’s rampant. It doesn’t make the test scores any less valid for their intended use.

CONCLUSION

This article just seems like a pseudo-scientific rant against IQ tests.

IQ tests aren’t perfect. They have a lot less utility than people think they do. That said, they do have some utility.

IQ tests are pretty good at discovering people at the extremes. One could argue that the folks at the extremes might warrant some different treatment.

IQ tests also do a decent job at identifying large gaps between individuals. This has less proven utility, but there is an idea that people with significantly different IQs perceive the world in different ways. This is a bit of a rabbit hole, but it’s an interesting line of inquiry.

tl;dr - Your IQ score is not you. Don’t worry about your score if it’s not at the extremes or if it’s not vastly different than your partner’s (it’s probably not, and if it is, you probably already expect that this is the case).


it's uncommon to thank someone here on HN. so I just say you have saved me a tremendous amount of time and if I knew how to sticky your post to the top (against all currently popular grain) I'd do so.


I appreciate that.

I’m glad that my reply was well-received.


IQ was invented by eugenecists.


I've never heard that say of Binet. But it doesn't matter. Ideas don't inherit morality. It's their application that counts. Pythagoras had some really outlandish ideas. But the formula holds.


I meant Lewis Terman.


"He is best known for his revision of the Stanford–Binet Intelligence Scales and for initiating the longitudinal study of children with high IQs called the Genetic Studies of Genius."

Just from spending 20 seconds on his Wiki page.

He is clearly not the original inventor.


There's some youtube videos by Dr. Tod Grande. (I know, sue me.)

IQ is about 4% of what makes up your personality. So whatever your intelligence is within a standard deviation, other factors are much more important.

TL:DR; it's better to be a track star with a big d*k than a fat genius in a basement apartment.


What is personality according to you? Or whoever Dr. Grande is?

> it's better to be a track star with a big d*k than a fat genius in a basement apartment.

Why is that? How easy is it to become a well-endowed track star? How easy is to become a genius? How many geniuses are fat? How many live in a basement? This is just distracting from any point related to intelligence and IQ.


> Or whoever Dr. Grande is?

Apparently he has a Ph.D. in Counselor Education and Supervision, who primarily spends his time psychoanalyzing pop culture and celebrities on Youtube. I guess in the year 2022 that makes him a qualified professional worth listening to and discussing on this forum regarding his thoughts on IQ?

IQ doesn’t make up anything of your personality.

It’s a hotly debated measure of intellect.

It being better to be a big dicked track star vs a fat genius has nothing to do with IQ as a valid measure of intelligence, or even personality as you were talking about. And is frankly really weird you brought that up.


This is so off that in W. Pauli terms, it's not even wrong.

TL:DR; monkey bests fish in tree climbing contest, credits higher IQ.


TTL:DR: Bro, be coherent.
