Math ability is one of the best proxies for IQ so I decided to create a little math test for anyone who’s interested. It’s completely anonymous. There are only 10 questions ranging from extremely easy to extremely difficult. The easiest question can probably be answered by over 99% of the general U.S. adult population while the hardest can probably be answered by less than 0.1%. To enhance the g loading, I picked questions that emphasized mathematical intuition and conceptual understanding as opposed to brute number crunching.

There’s no time limit, but try to take the test in one sitting without use of calculator, pen, paper or other aids, though I doubt they would help much. Take the anonymous poll to let us know how you scored.

Mike Turnersaid:

Are you sure about the answer to ‘How many two-inch tall cubes are needed to make a six-inch tall cube?’ I expect it to be 3 times what you accept as an answer, but maybe I am misunderstanding something.

I scored 8/10. I don’t have a high math IQ so whatever that is – assuming 120s – it’s probably accurate. Though maybe if I was earnest on the ones I didn’t understand, I would get 9/10.

If my theory is correct and Mugabe took the poll 10 times, they are, at least, 2 obvious liars in the 17 (26 – 9) persons who took the poll. It would be nice if I am right not to post my previous comment to see who else is bragging about a perfect score. Or even ask who scored a ten …

If I am wrong, obviously this comment is useless 😂

I got 9 out of 10 on this, and like other people said I didn’t exactly understand the last two questions, but reading your blog a lot I learned a bit about this kind of math and figured what you were going for. I’m guessing my answer for the last one was too high.

I’m American, I never took the SAT because I dropped out of High School. However I took the GED and got a perfect score on the math portion, though I think that test has a pretty low ceiling in terms of the most difficult questions on there. Also, math was my best subject during my primary school years, but I’ve not studied it in any detail for maybe 7 years now. Highest class I took was Calculus AFAIK.

I’ve never taken an official IQ test, but I personally reckon my IQ is between 1-2SDs above average. My mathematical IQ is probably close to 130 while my verbal IQ is probably closer to 100-110. Could be pretty off on this dichomoty though… that’s just my idea based on experience in primary school.

I got 10 with same answers. I probably did it when there were the incorrect answer. As I thought all my answers were correct, I believed you had score it out of 9 just to check out false reporting 😊

I don’t think the math ceiling is higher than 135 (99%).

well if we ignore the ten fake tens by Mug of Pee, it seems about 10% of people here got 10. In the general population that’s IQ 120 but assuming this group is 25 points above average with normal variability, it might be IQ 145.

also seems bottom 4% score 5 or less. In the general population that would be IQ 74, but if we add 25 points, that would be IQ 99.

so 5 = IQ 99

10 = IQ 145

If we assume linear

6 = IQ 108

7 = IQ 117

8 = IQ 127

9 = IQ 136

just a preliminary guess

Brunosaid:

It’s difficult to know for me because I am quite trained in mathematics. I was proposed for Math Olympiad at 16 yo but didn’t do it because I used to go on holiday to Spain 3 months every summer and my parents weren’t interested by school grade or performance …

I remember LoB spoke about a test with 3 questions given to Harvard students who got only 25% 3 out of 3 when I seemed to me being of 125. So I may be 10 points short.

For whatever reasons, I have crystallized more intelligence on math despite being weak in spatial.

Flaminhotcheetossaid:

I got a 9. If 9 = 136 (converting to about 99th percentile assuming SD = 15) then that would be consistent with my SAT math score (770; 98 percentile).

Billysaid:

Pumpkin this seems to relate to working memory (my intuition). 127 is essentially my working memory and math IQ probably relies a lot on it.

Brunosaid:

If this is 145, Taleb regularly asks question wich would be 20 points higher, thius 165. I have answered correctly only once because I hate the guy who is a fake mathematician.

IMO would be then 40 points higher at least when I thought there would be 172. But it would make sense because there is only 2 or 3 perfect scorers in the all world. I just thought the competition was not known enough to reach the super smarts kids lost in an Alpes village en somewhere in central China because it’s math teacher wouldn’t be neither good enough to notice nor knowledgeable enough to know the IMO (nor caring enough about pupils).

For me, my math teacher hated me but the dean of my high school had a PhD in math and proposed me to the French selections in Paris …

The difference between 1 in 1,2M and 1 in 40M, is that out of 120M born, you need to reach 4% in the first case (172) but 80% in the second case (182) …

French system selects on knowledge based on a program you acquire in preparatory schools during 2 to 3 years after higher school. The higher IQ, the less you will have to work but due to the routinized testing, wich unlike MCQ doesn’t have an essential time constraint and basic tasks, you get something more like chess where rote memory is the most important factor.

Then elites are selected by one school ENA wich is based on law and public policies knowledge. So there, even if the selection is the highest in terms of attractivity, correlation with IQ is even lower.

They are two exceptions : students who enter Ecole Normale supérieure d’Ulm in pure math (40 people) tend do be very bright. This school compare to no other in termes of bachelor getting the field medal.

And students from engineering school Ecole Polytechnique who enter the corps des Mines (15 people out of the 400 students) tend to be very bright. So for those 55 people, probably their IQ is above 135. But that’s a very tiny group ans the power is in the end of another group of 80 people per year out of ENA.

Then the larger french elite 4000 people out of French management program and engineering schools have probably an average IQ around 125 and are very industrious. There is no positive discrimination for them. And they are in all corporate world.

3 out of top 5 management programs (business schools without professional experience) are French:

And our top engineering schools are more selective that our business programs, so they don’t have much competition in the world. And it’s because of the selection process : you select students based on high school grades, they prepare a vast program during 2 or 3 Years, and the Grandes Écoles select the best scorers they can (some have joint exams other have separate one, but they are all based on the same national program).

Out of 800k people each year , 10k prepare management schools and 15k prepare Engineering schools. The three best French schools select 1200 students. They also select 600 students with a bachelor (that’s were you get some legacies) and 600 from foreign countries (same). It’s the same selection process for engineering schools.

So in general, you have to sacrifice your 18-20 in France if you want to join this club (2400 people) and your 20-28 if you want to join the ENA and Corps des mines tiny group (80+15).

There are plenty of other small prestigious programs only known by French elites but that will give you prestige for life here …

Bruno what do you do for a living anyway?

Austin Slatersaid:

I love Taleb’s 110 IQ reply guys who pretend to understand anything he says.

And the last two questions are for people who read your blog and can recognize the sd for height and weight, in order to guess the simple correlation. Same for skills & height in NBA.

they don’t have to know the SDs but yes, being familiar with the concept of regress is a hue advantage on the last 2 so they’re perhaps not good measures of IQ. still i’m shocked anyone got #10 as the reasoning is very esoteric. I wonder if they got it by accident

though the last 2 might be good measures of IQ for the vast majority of people who haven’t read about regression and just use their common sense to figure it out.

gssaid:

I’m not sure its easy to test mathematical reasoning – study has way to large an effect. In my experience that average IMO medalist is prob around 3 sigma, great, but nothing too exceptional. Practice is the key.

Keffylsaid:

Solution for 10 that doesn’t require you to know SD. It gave the correct answer, though I’m not wholly confident in the method’s correctness.

You have to assume that the components account for 100% of the variance, which you haven’t specified but I don’t think it’s solvable otherwise, then since Var(Basketball) = Var(Height) + Var(Practice) + Var(Speed) + Var(Coordination) = 4Var(Height), the standard deviation is twice as big for basketball as it is for height (since variance is standard deviation squared) and the slope of the regression is 0.25 (since Var(Height)/Var(Basketball) = 0.25, i.e. variation in height accounts for 25% of the variation in Basketball playing. It essentially works the same way as heritability where you treat Height as G and the rest as E.). You can use that to find the correlation coefficient and solve it that way, but I hadn’t thought of doing that, so instead I treated the 12 inch gap as a gap of 1 arbitrary unit (some multiple of the standard deviation) which means there is a 2 arbitrary unit gap in-between the best and worst basketball player. Since slope is 0.25, for two arbitrary units of basketball there are 0.5 arbitrary units of height, i.e. 6 inches.

Again, you have to assume that the components account for 100% of the variance, but I think this is true for all solutions. Since you haven’t mentioned this, I don’t think the question is strictly solvable.

I treated the 12 inch gap as a gap of 1 arbitrary unit (some multiple of the standard deviation) which means there is a 2 arbitrary unit gap in-between the best and worst basketball player.

I’m not following the logic.

Keffylsaid:

I will admit this might not have been the clearest solution, it was however what I had thought of while working on the problem.

Let’s say the gap between heights is of X standard deviations. Let’s say we set the SD for height to 1 (which is probably what I should have done), then the SD for basketball is 2. At this point, the more obvious solution would have been to say that there was a gap of X in height and therefore a gap of 2X in basketball, and proceed from there. Instead I invented a unit such that a gap of X SD in height corresponded to one unit. In this situation, one unit would correspond to X, but let’s say the SD was 2, then one unit would be 2X. It was just a way to solve the problem without setting the SD, but there’s not really a reason to do that.

Despite that decades-long legacy, the president insisted that, perhaps excluding Abraham Lincoln, “nobody has done more for Black Americans” than he had, including Lyndon Johnson, who passed the Civil Rights Act in 1964.

“How’s it worked out?” Trump retorted. “If you take a look at what Lyndon Johnson did, you think?”

It was unclear what the president meant.

Hahahaha. I hope trump gets his own radio or tv show after he loses in November.

Mug completely destroys the aesthetics of this blog. Especially with his beige gravitar…probably a pretty good representation of his whiteness and his overall blandness in terms of persona.

Yes, I thought this obvious to anyone. He used to go by ‘Robert Gabriel Mugabe,’ so Mug is an homage to his legacy using that pseudonym while converging on the fact that indeed he calls Pumpkin “peepee.”

7/10, which seems to be consistent with my high average iq. However when I first took the test I misunderstood question 7 and scored 6, I don’t know if I’d be penalized for that.

Scores of 9 equate to a 151. I got all 15. Super easy test for anyone on this blog tbh. May have to consider that it was in the “Denali” section of the DM lol.

I ended up here by chance via Cochran’s blog, saw the test, though I’ll bite, and took it.
First try was 5/10; turns out I hadn’t read the questions carefully lol. 2nd try got 10/10
I find it hard to explain how I ended up with the correct answers for questions 9 and 10 (English isn’t my first language and I’m not good with math terms in English) but I supposed they’re related and the same logic applies to both. Does it?

For the record, since you’ve written about IQ tests not yielding consistent results, I’ve taken various Mensa-grade IQ tests multiple times over the years in different states (fresh, tired, sleep-deprived, hungover) and the result is always somewhere around 130. I can never answer the final questions in the allocated time so I know there’s a hard limit on what I can grasp of this world. Meeting more intelligent persons is both fascinating and depressing!

8/10, Smoothness in increasing difficulty from item to item is always a problem for tests, so nobody should go nuts . I mean, as many might notice, there must be, say, one more item between n8 and n9 . Was fun anyways👍

wow. interestingly, since in n5 I have mistakenly read it as “5 times more” instead just “five more” I got it wrong. It means that my guessing on n9 or n10 was right 🤦♂️

Some other relevant stats:
IQ: 139 (SB)
SAT math score: 550 out of 800

Perhaps it is just sour grapes on my behalf but I tend to agree with Marc Lamont Hill that the SAT is a measurement of how middle class you are rather than a measurement of intelligence. I come from an extremely low income family and attended shitty public schools my entire life. I don’t blame my mathematical mediocrity on educational quality, however, so much as the attitude of the underclass towards education. my cavalier attitude towards education likely reflected that of the single !other who raised me, who was an 8th grade drop out. Personally, I treated the SAT like an eye exam; something you just walk in off the street and take to get your guidance counselor off your back. I attribute my stellar 770 verbal score to a love of reading more than to family background or formal education.

Just took the test a second time and scored an 8. I completely misread the question about garden hoses the first time through. Apparently my reading comprehension isn’t as strong as I tell myself it is. Ha.

I might have about the same IQ score and scored an 8 as well. Also scored similarly on the SAT Math, and my reading score was also higher, though not as high as yours.

Is your SB CPI significantly lower than your GAI? That might have something to do with poor math scores and reading comprehension.

Pumpkin, since 40% of Hispanics are monolingual, if the VIQ PIQ gap is 2 points, if the sample size was 100% bilingual, it would be more than 2 points right?

Pumpkin, I scored 29 on ACT Math. I hadn’t studied for the test and was mostly or completely unfamiliar with some of the types of math it covered, particularly plane trigonometry. My composite was 33, with 36, 35, and 33 on English, Reading, and Science respectively. How high do you think I could have scored on ACT Math with the proper preparation to reach my maximum score?

For reference, I got 16 scaled on the WAIS-IV arithmetic. I think I underperformed on that due to sleepiness, but it is what it is.

i.e., at least one of the arithmetic questions I missed was because I zoned out while the question was being read and the administrator wouldn’t repeat it

If you got a 29 with no prep and very little familiarity, you’d easily get a 36 with a little prep. Your 29 is already ridiculously high, especially with little familiarity with the content.

Pumpkin, my highest SAT Math was 780, even if everyone took it multiple times and studied hard, would it still be the case that the 780 is at least a 115 math iq?

8/10. 11/20 on the number sequence test but I had fallen asleep after sloppily answering some of them and forgotten which they were when I woke up, also skipped one of the first 10 (which generally were easy?). So I did rush.

With regards to this test, for the 9th question I had both the correct answer and an incorrect one in mind, I submitted the incorrect one. I guessed 12 inches (same as tallest person) though I knew that answering like this would not minimize the error across these kinds of questions but that’s entering statistical territory that I’m not familiar with (I never went to high school). Take a bipedal robot factory, are you seriously going to guess the heaviest robot is only 6 inches taller than the average one and not just a beefed up version of the tallest one? So to answer this question I’d have to get into the mindset of statistics and genetics. My other guess was 6 inches but that was based on a visualization of 2 containers holding 12 inches and 50 pounds maximum, and as 25 pounds fill to 50 pounds, 12 inches empties to 6 inches. No idea how nonsensical or not that idea was.

said:I will admit this might not have been the clearest solution, it was however what I had thought of while working on the problem.

Let’s say the gap between heights is of X standard deviations. Let’s say we set the SD for height to 1 (which is probably what I should have done), then the SD for basketball is 2. At this point, the more obvious solution would have been to say that there was a gap of X in height and therefore a gap of 2X in basketball, and proceed from there. Instead I invented a unit such that a gap of X SD in height corresponded to one unit. In this situation, one unit would correspond to X, but let’s say the SD was 2, then one unit would be 2X. It was just a way to solve the problem without setting the SD, but there’s not really a reason to do that.

being anti-islam is no different from being anti-communist or whatever.

said:rr reminds me of ben affleck in that exchange he had with sam harris. sam harris is gross but being anti-islam doesn’t make you a racist.

for one thing there are white muslims in the balkans and the caucasus.

but the kill shot is:

1. religion is NOT genetic.

2. UN-like ALL other religions, islam is a VERY explicitly POLITICAL religion.

said:Despite that decades-long legacy, the president insisted that, perhaps excluding Abraham Lincoln, “nobody has done more for Black Americans” than he had, including Lyndon Johnson, who passed the Civil Rights Act in 1964.“How’s it worked out?” Trump retorted. “If you take a look at what Lyndon Johnson did, you think?”

It was unclear what the president meant.Hahahaha. I hope trump gets his own radio or tv show after he loses in November.

islam has its own mishnah and talmud and 613.

said:of course one might claim that judaism is also explicitly political.

but in two senses.

1. ancient judaism DID prescribe a form of government. but israel doesn’t follow it.

2. modern judaism may prescribe a form of government too, but only in the sense that “whatever the form of government, jews control it”.

and islam is really just universal, militant, ersatz judaism.

that is, in 2020 being “alt-right” is like being a “hippie” in 1968, but less gay.

but in my case it’s more than just contrarianism.

I did the first 8 questions easily,but I think I only got the last two questions right for reading your blog with some regularity.

The last two don’t seem very culture fair.

said:I ended up here by chance via Cochran’s blog, saw the test, though I’ll bite, and took it.

First try was 5/10; turns out I hadn’t read the questions carefully lol. 2nd try got 10/10

I find it hard to explain how I ended up with the correct answers for questions 9 and 10 (English isn’t my first language and I’m not good with math terms in English) but I supposed they’re related and the same logic applies to both. Does it?

For the record, since you’ve written about IQ tests not yielding consistent results, I’ve taken various Mensa-grade IQ tests multiple times over the years in different states (fresh, tired, sleep-deprived, hungover) and the result is always somewhere around 130. I can never answer the final questions in the allocated time so I know there’s a hard limit on what I can grasp of this world. Meeting more intelligent persons is both fascinating and depressing!

First 8 are very easy with no time limit. I don’t know if I would have intuited the final 2 without learning about regression from this blog, though.

Some math stats:

34 on ACT math section

129 on WRAT-4 math section

19(perfect score) on WAIS-IV arithmetic

pumpkinperson

said:A 19 on WAIS-IV Arithmetic equates to IQ 145 (U.S. norms), very similar to your 10 on PATMA which I’ve tentatively assigned IQ 147 (white norms)

Tez

said:I scored a 7

Some other relevant stats:

IQ: 139 (SB)

SAT math score: 550 out of 800

Perhaps it is just sour grapes on my behalf but I tend to agree with Marc Lamont Hill that the SAT is a measurement of how middle class you are rather than a measurement of intelligence. I come from an extremely low income family and attended shitty public schools my entire life. I don’t blame my mathematical mediocrity on educational quality, however, so much as the attitude of the underclass towards education. my cavalier attitude towards education likely reflected that of the single !other who raised me, who was an 8th grade drop out. Personally, I treated the SAT like an eye exam; something you just walk in off the street and take to get your guidance counselor off your back. I attribute my stellar 770 verbal score to a love of reading more than to family background or formal education.

Tez

said:Just took the test a second time and scored an 8. I completely misread the question about garden hoses the first time through. Apparently my reading comprehension isn’t as strong as I tell myself it is. Ha.

Billy

said:I might have about the same IQ score and scored an 8 as well. Also scored similarly on the SAT Math, and my reading score was also higher, though not as high as yours.

Is your SB CPI significantly lower than your GAI? That might have something to do with poor math scores and reading comprehension.

said:Pumpkin, practice effects from ravens only minimally affect wais matrix reasoning right, did to different types of items?

said:Pumpkin, since 40% of Hispanics are monolingual, if the VIQ PIQ gap is 2 points, if the sample size was 100% bilingual, it would be more than 2 points right?

said:Interesting. So based on the test’s you’ve taken here:

Gestalt IQ 137

PATMA IQ 116

COMPOSITE IQ 132which makes sense since it’s in between your WAIS-IV (IQ 120) and your SAT (IQ 138)

Ganzir

said:Pumpkin, I scored 29 on ACT Math. I hadn’t studied for the test and was mostly or completely unfamiliar with some of the types of math it covered, particularly plane trigonometry. My composite was 33, with 36, 35, and 33 on English, Reading, and Science respectively. How high do you think I could have scored on ACT Math with the proper preparation to reach my maximum score?

For reference, I got 16 scaled on the WAIS-IV arithmetic. I think I underperformed on that due to sleepiness, but it is what it is.

Ganzir

said:i.e., at least one of the arithmetic questions I missed was because I zoned out while the question was being read and the administrator wouldn’t repeat it

Rahul

said:If you got a 29 with no prep and very little familiarity, you’d easily get a 36 with a little prep. Your 29 is already ridiculously high, especially with little familiarity with the content.

Rahul

said:Pumpkin, my highest SAT Math was 780, even if everyone took it multiple times and studied hard, would it still be the case that the 780 is at least a 115 math iq?

Rahul

said:Pumpkin, can a good matrix reasoning score make up for a lower figure weights score, hence still retaining the Math ability.

said:8/10. 11/20 on the number sequence test but I had fallen asleep after sloppily answering some of them and forgotten which they were when I woke up, also skipped one of the first 10 (which generally were easy?). So I did rush.

With regards to this test, for the 9th question I had both the correct answer and an incorrect one in mind, I submitted the incorrect one. I guessed 12 inches (same as tallest person) though I knew that answering like this would not minimize the error across these kinds of questions but that’s entering statistical territory that I’m not familiar with (I never went to high school). Take a bipedal robot factory, are you seriously going to guess the heaviest robot is only 6 inches taller than the average one and not just a beefed up version of the tallest one? So to answer this question I’d have to get into the mindset of statistics and genetics. My other guess was 6 inches but that was based on a visualization of 2 containers holding 12 inches and 50 pounds maximum, and as 25 pounds fill to 50 pounds, 12 inches empties to 6 inches. No idea how nonsensical or not that idea was.
