A reader sent me the following email:
I recently stumbled upon your blog and find it quite fascinating. I’ve been interested in IQ and psychometrics for many years and have taken many online assessments and standardized exams to gauge my own IQ. Interestingly enough, however, it seems that the more tests I take, the less conclusive my IQ range becomes due to high variances in scores.
This is why I’m turning to you, an expert on this topic, to request an estimation. For one, in elementary school I was tested for the gifted program and unfortunately rejected. This tells me that my childhood IQ was beneath 130, which I believe is the cutoff for most school gifted programs.
Yes, but the mere fact that you were tested for gifted suggests you were probably close. Perhaps 125 (U.S. norms).
The reader continues:
However, all the standardized exams that I’ve taken (which you’ve claimed to be valid proxies for IQ) seem to tell a different story. My scores are as follows:
SAT (Taken 2017) – Math 800, Verbal 720
ACT (Taken 2017) – 34 Composite
I was also ranked 6/945 in my high school class for GPA. I figured this might be relevant given the large sample size and the notion that academic performance correlates with IQ. Since my high school was in a lower-middle class area, we can assume a relatively normally distributed sample with an average akin to the American population average. All the students ranked ahead of me were Asian, and I am South Asian myself (Indian).
A post-2016 SAT score of 1520 equates to an IQ of about 132. I’ve done very little research on the ACT but apparently a 34 on the SAT is like 1535 on the post-2016 SAT which equates to an IQ of 133.
The reader continues:
I’m also currently an undergraduate (a double major in mathematics and economics) and have been studying for the GRE. My diagnostic score for the GRE, with little to no preparation, was a 157 Verbal and 166 Quantitative. I’ve since improved to a 163 Verbal and 167 Quantitative for my second practice exam.
Averaging across both sittings, you scored 160 V and 167 Q for a composite of 327. Preliminary research suggests this equates to an IQ of 143.
Averaging the SAT, ACT & GRE together, your mean IQ equivalent on college admission tests is 136. Normally I don’t endorse the averaging of tests but these particular tests are so similar that it’s not worth the trouble of considering them different tests.
Meanwhile, your score on an official IQ test was probably around 125.
Given that official IQ tests correlate no more than 0.7 with college admission tests, your score on a composite of both types of tests would be about 134.
I had a couple follow-up questions which the reader answered in another email:
my socioeconomic background is generally lower-middle class. My high school was located in the suburbs but had many students from the nearby urban area…
One caveat to my socioeconomic status, which applies particularly to my situation, was that I grew up in a single-parent household. Both my parents were highly educated (held graduate degrees) but my father unfortunately passed away when I was young.
I’m very sorry to hear that, but at least he lived long enough to pass on his high IQ genes through you.
This obviously influenced my household income.
As for my ethnic background, I come from a Brahmin ancestry. Although I’m not a practicing Hindu, I recognize that this could have played a role in my generally well-educated familial background.
you are by and away the most callous person ive ever come across real life or otherwise PP. shittiest quality in a person and i dont know why you have so much of it…
Pumpkin this is hopefully my last comment in this torture-chamber but you should really stop being so insensitive to people and biased in your sciences. also it proves that your incompetency outweighs your competencies for sure.

i believe there is also a small IQ boost merely from having to navigate TWO cultures and two genuinely different, totally unrelated languages. one’s own and that of one’s environing society.
so israelis don’t have this, obviously.
and ultra orthodox jews don’t have it in the US. they shut themselves off.
macrocephaly is like macropenis...there is such a thing as too much of a good thing...or more is pointless. said:

oprah’s yuge head (actually tiny) compare to other rich people: musk, bezos, gates.
the only famous people i know who have yuge heads are…bill clinton…i’m not famous…but my head fits my body…big people have big heads…yes peepee, polynesians have bigger brains than koreans. deal with tulsi gabbard freakishly large head!
The brains of both Clinton & Tulsi could fit in Oprah’s cranium at the same time. They’re not even in the same category as her.
Oprah exceeds 99.9999% of Americans on BOTH money and brain size (the two most Darwinian correlates of IQ).
NOW YOU TELL ME MY SISTA, WHAT COULD BE BETTER THAN THAT??????
the "trashiness" of "white trash" is only apparent...so many small things... said:
ashley judd in De-Lovely for example.
when america was 90% white…in 1970…it was better.
stop tearing at the shirt of white men bipocs!
note the white suits.

This is what +5 IQ points does to a society.
