Many high IQ societies accept scores from the GRE, LSAT and other graduate school admission tests. For example Mensa, which requires you to be smarter than 98% of Americans (for your age group), will accept you if your LSAT score is higher than 95% of LSAT takers. But how does Mensa know that being smarter than 95% of LSAT takers is equivalent to being smarter than 98% of Americans? I don’t think they do, they just know that since the LSAT population is smarter, one’s percentile among the LSAT population underestimates one’s percentile among Americans, but conservatively assumed the underestimation is small to avoid admitting unqualified people. So to Mensa’s credit, they probably erred on the side of maintaining standards (instead of profits) and rejected LSAT scores below the 95th percentile, even though many of those people likely qualified.
I can’t find much data on the IQ distribution of LSAT takers, but assuming they’re roughly equivalent to GRE takers (both tests are for admission to post-bachelor degree schooling), then the following is relevant:
In a sample of people who took both the GRE and the SAT (circa 1990), the mean GRE and SAT verbal was 510.1 (SD = 107.7) and 518 (SD of 104.7) respectively. Rare norming studies show that if all Americans took the SAT circa 1983, the mean and standard deviation (SD) would have been 376 and 102 respectively, which means that on an IQ scale (mean 100; SD 15) they had a mean verbal IQ of 121 (SD 15.4).
Now assuming the same for the LSAT, the 95th percentile (+1.66 SD) equates to an IQ of:
1.66(15.4) + 121 = 26 + 121 = 147
So when Mensa was screening out anyone with LSAT derived IQ scores below 130, they were also screening out everyone with IQs below 147!
yes the old GRE V portion has a very high ceiling. said:
now see how objective mugabe can be.
1. perfect scaled scores of 800 weren’t that rare on the Q and A sections of the old GRE. they were rare on the V section…even though one could get several answers wrong and still make an 800.
2. so the GRE V was a super high ceiling? answer: yes but not as high as may appear because unlike the LSAT the GRE will have a certain % of ESLs.
i STILL have a crush on LOADED. said:
so if ESLs were 25% (i doubt they were more than 10%) and none of them scored 800 then the percentile for 800 isn’t changed much.
i only prepped in earnest for the A section because i had trouble doing it under time. it’s identical to a section of the LSAT…or was. it’s just logic puzzles. doing logic puzzles really fast is hard but it’s pure speed so you can learn it.
Logic games is by far the most preppable section of any standardized test.
i STILL have a crush on LOADED. said:
and by “prepped” i mean i just did all the A sections i could find. ETS published past tests and another group made up tests.
it was fun.
even on test day i answered the last question on the A section a split second before time was called.
the virtues of OCD? said:
and it’s only because mugabe is OCD that he kept taking tests.
he didn’t have much to improve in the first place.
he max(x)ed his performance after taking just a few old tests.
the OCD actually comes from my mom’s side. her sister and her father.
all of them were very pretty. said:
3+ times mugabe has had very pretty chinawomen VERY interested in him.
but i’d rather fap.
if all they wanted was sex i’d be glad to oblige them.
but that’s never all women want.
Even if LSAT test takers had a 121 average IQ, sd would be far smaller than 15. It’s not the same to have a cut of the the right part of the bell curve (institutional selection) than move the bell curve to the right side (like differences in population IQ).
If you select a group at 1 in 10. Their average IQ is 125. But if you select 1 in 10 in this group, the IQ is not 150 (125 + 25) but 138 (1 in 200). Because you just had cut a right wing piece of the Bell curve without moving it to the right (meaning keeping a 15 sd from the higher average).
Mensa is probably right.
So the iq sd among lsat folks is like multiplying the normal iq SD (15) by the correlation between iq scores and lsat scores?

great german philosophers post heidegger = null set. why? said:
Hans Heinz Holz also says that dumb pipo mistake socialism for redistribution.
but what it really means is that all bidnesses are employee owned.
all power to the soviets.
“the soviets” in the above doesn’t mean what peepee thinks it means.
“the soviets” = labor unions = would be employee owners.
the LSAT and MAT don't have this multi-section THANG! said:
the “modest” correlations between the GRE V, Q, A sections makes it…
the world’s best test of high end g.
Victor Henrique said:
Probably the standard deviation of people who take the LSAT is much smaller than people who take the GRE, the GRE groups many populations with different IQ averages (e.g., physicists, biologists, educators).
The high end of the IQ spectrum is almost entirely dominated by physicists and mathematicians, so you might be more likely to find someone 160+ in the general population than among lawyers.
Yes, good point about many different disciplines taking GRE
