Commenter chartreuse argues that not only is the SAT a valid measure of intelligence, but that it’s even better than official IQ tests. I wouldn’t go that far, but the SAT is unique in that it’s been used to collect data on millions of test takers. For that reason, it’s an especially reliable source for documenting racial differences in IQ within America. One can convert SAT scores on the post-1995 SAT into IQ equivalents using this formula I created:
IQ equivalent (U.S. norms) = 23.835 + 0.081(new SAT score)
One problem is that although the SAT is given to an enormous sample of Americans, it is not given to a representative sample of Americans. Only about the most academically successful third of American 17-year-olds take the SAT, however one might crudely adjust for this filtering.
For example, the average white SAT taker has an SAT score of 1068 which equates to an IQ of 110 (U.S. norms); 107 (U.S. white norms). But we know that the average IQ of all post-boomer Whites is 103 (U.S. white norms); 100 (U.S. white norms). Thus in the chart below, I just assume that the college bound segment of each race is 7 IQ points higher (U.S. norms) than the general U.S. population for each race:
| race | mean sat of college bound seniors | mean iq equivalent of college bound seniors (u.s. norms) | mean iq equivalent of college bound seniors (u.s. white norms) | mean estimated iq in the general u.s. population (u.s. norms) | mean estimated iq in the general u.s. population (u.s. white norms) |
| asian americans | 1091 | 112 | 109 | 105 | 102 |
| whites | 1068 | 110 | 107 | 103 | 100 |
| american indians | 982 | 103 | 100 | 96 | 93 |
| mexican americans | 916 | 98 | 95 | 91 | 88 |
| puerto ricans | 917 | 98 | 95 | 91 | 88 |
| other hispanics | 932 | 99 | 96 | 92 | 89 |
| african americans | 864 | 94 | 91 | 87 | 83 |
If anything, the chart above overestimates the general population score gaps between different races, because it assumes a 7 point IQ gap between the SAT population and the general population in every race, but in non-Asian minorities, that gap could be larger because a smaller percentage of those races go to college, and thus the college bound elite are even more filtered for ability.
It should be noted that the relatively small gap between Whites and Asian Americans might be because (1) the SAT does not emphasize spatial ability, and (2) Asian Americans are not equivalent to East Asian Americans, but include non-white caucasoids and southeast Asians who have australoid admixture.
I’m adopting charteuse’s method… Trying to adhere to strict syntactical rules is too tedious… I’m going to be elliptical… With man y ellipses…
I’m sorry, Pumpkin. I don’t know much about stats… I haven’t studied anything like that for many years. But I will do research for you if you’d like.
why is everyone so dumb? i’d kill myself if i got 1100. i’m frustrated at being different, and i don’t even think im that smart.
What is your IQ?
unknown, and 1450 on sat post 95
why is everyone so dumb?
Intelligence reached an evolutionary equilibrium.
Higher intelligence was not needed for survival.
Holding thoughts in my head is difficult for me.
I can’t add grocery prices in my head at the store.
I am slower than 81 percent of the white population.
I wish I was faster, I could then program Nvidia GPU’s.
My verbal comprehension is in the top two percent.
Animekitty- I saw somewhere on here that you are from New Mexico. Are you Hispanic? If so are you non-white/native american? It would be very interesting to see a Mongoloid who has very low Mathematical Abilities but very high verbal abilities.
I am Caucasian.
Nothing special.
My maternal grandmother was one forth Cherokee I think?
My great aunts on my fathers side were half native american.
I do not know if they were on his mothers side or fathers side.
I think my great aunts and grandparents(maternal or paternal) were half siblings.
It would be nice if I could hold more numbers in my head.
Mental manipulation of my thoughts would be fun.
I now have Prozac in my med pack.
I hope it fixes my OCD.
What do you mean with slow?
Is it just the way you think, or is it your whole body (your movements)?
A couple years ago I looked for a way to improve my reaction time for sports.
After some time I found the perfect way to achieve that.
I don’t know if it’s a coincidence, but since then my creativity has skyrocket.
I have improved my ability to see patterns or structures and ask the right questions to find new solution to old problems.
I read somewhere (maybe here) that reaction time correlates with working memory, isn’t that something you said you lacked?
TVP“What do you mean with slow?
Is it just the way you think, or is it your whole body (your movements)?”
It is the way I think based on my wais 4 scores.
Processing speed 86
Working memory 95
Those scores have percentiles within the population.
I put my raw scores on this blog as a comment and PP said they were interesting and that my profile would help to understand how tests work but said nothing else.
As with my body it is not my whole body just my hands.
I can’t play shooter games and I type with only my index fingers.

I definitely have some elements of that.
My medication works good, except intuitively it causes weight gain (wikipedia confirms), since it lowers testosterone/libido, that, common sense would tell us helps academic performance. I don’t know why I obsess about that. I have the obsession but not as much the compulsion.
I was looking at this some more, and I found an NCBI article which states it causes trouble in tissues, of course that, based on the biological effect of developmental plasticity that would take a while, perhaps as long as even the mental effects. That’s why I put the date, it is a point of reference for things like this.

Maybe you could work for Google so you would not feel so lonely.

Hmmm… I appear to be an anomaly among African Americans, especially considering that my fraternal-twin’s autosomal results is 84% Sub-saharan. There may be a 3-5% difference between us, but either way I would still be considered above average since the average Black american is about 75%.
Here’s my SAT history:
10th grade PSAT October 2014- Total: 1690 ( 86th Nat. percentile)
Reading: 590 ( 92nd percentile) Math: 580 ( 89th Nat. percentile), Writing: 520 (94th Nat. percentile)
Composite: 1170
The New to Old SAT conversions are based on Collegeboard’s own score converter based on the concordance tables. If you notice a difference between section scores’ sums and totals in these conversions, this due to them being mere estimates.
11th Grade PSAT October 2015 ( The New one out of 1520)-
Total: 1360=1920 ( 98th Nat./ 98th User percentile)
Math: 720= 690 on old SAT (99th Nat./ 98th User percentile)
R+W: 640 = R:590+ W: 570 on old SAT. (95th Nat./ 94th User percentile)
Estimated composite of 1300 on old SAT.
March 2016 SAT- Total: 1340= 1880 on old SAT (94th Nat./ 90th User percentile)
Math: 690= 660 on old SAT ( 94th Nat./ 91st User percentile)
R+W: 650= R:570+ W:630 ( 90th Nat./ 84th User percentile)
Estimated Composite of 1280 on old SAT. I considered this my slump and luckily made up for it the following June
June 2016 SAT- Total: 1420= 2020 on old SAT ( 98th Nat./95th User percentile)
Math: 730=700 on old SAT( 97th Nat./95th User percentile)
R+W: 690= 640+650 on old SAT ( 96th Nat./ 92nd User percentile)
Estimated composite of 1370 on old SAT.
According to your formula, my current IQ seems to be about 135 if I were to use the concordance Composite from the June 3 exam.
Note: I’m aware that due to factors concerning my preparation for the exam and the current format of the test, plugging in estimates into a linear equation may not necessarily be a good indicator for my actual IQ. However even with my first/lowest composite being 1170 as a 10th grader, I would still be quite an anomaly as a rather less-than-mixed-race African American.
