I can not find a single published study correlating the LSAT with any other intelligence test although the data certainly exists. For example a 1985 study found a 0.72 correlation between LSAT and SATs in 5,854 students, though whether this study was ever published and where, I know not.

From 1948 to 1981, the LSAT was scored using a 200 to 800 point scale similar to the sub-scales of the SAT. Then from 1981 to 1991, it used a 48 point scale. Then starting in 1991, scores were expressed using a 120 to 180 scale. It is this latest version that I discuss in this article.
According to wikipedia: “Although the exact percentile of a given score will vary slightly between examinations, there tends to be little variance. The 50th percentile is typically a score of about 151; the 90th percentile is around 165 and the 99th is about 173. A 178 or better usually places the examinee in the 99.9th percentile.”
In other words, assuming a bellish curve, LSAT takers have an LSAT mean of about 152.1 and an SD of about 8.8.
Here’s a reddit thread where people listed their scores on both the LSAT and the ACT/SAT.
Because the SAT is constantly changing, I decided to focus on the LSAT-ACT correlation, ignoring the SAT.
The correlation between self-reported LSAT scores and ACT scores was +0.47 (n = 21).
Because I know a lot more about how SAT scores relate to IQ than I do about how ACT scores do, I converted all the ACT score to IQ using table A.1 from a 1999 paper by Neil J. Dorans:

The LSAT scores of the sample had a mean of 163 (SD 9.03) and the ACTs converted to SATs scores had a mean of 1307 (SD 161). Then using my formula for converting the post-April 1995 to pre-March 2016 SAT to IQ (IQ equivalent = 23.835 + 0.081(SAT score)) the sample had a mean IQ of 130 (SD 13).
Thus, the formula for equating LSAT to IQ (U.S.) norms:
IQ = [(LSAT – 163)/9.03](13) + 130
Recall that above we estimated LSAT takers have an LSAT mean of about 152.1 and an SD of about 8.8. So on the standard scale where Americans average IQ 100 with an SD of 15, the law school-bound elite average IQ 114 with an SD of 12.7, at least in the recent decades.
You think Philosemitic’s favorite president is Woodrow Wilson?
Wilson was being blackmailed by jews.
Since 2 or 3 years, the top 1% is 175 and not 173. That’s why Harvard & Yale average score have moved up similarly to that level.
The median score has moved up 1 point to 152.

The annoying thing with those scholastic tests is that they aren’t constant. So different generations are induced into false inferences about one person’s relative rank. Like G. Bush 1206 SAT score believed to be average when it was > 1,5 sd.
What are your IQ estimates for International mathematical olympiad 1.Perfect scorer(You said 175 at one point in time)2.Average gold medallist3.Average silver medallist4.Average bronze medallist. Physics olympiad should be 1 SD lower than mathematical, I assume. Steve Hsu’s friend who worked with the USA olympiad mathematics team has estimated that gold medallists are 153 IQ on average. Also, what is your current estimate for terence tao? You have implied that Grigori Perelman is 1 SD higher than him, which I think is correct. Also what is your estimate for Evan O’Dorney?(The Irish spelling bee champion, Rank 2 in a mathematical olympiad, white trash striver, homeschooled John Stuart Mill manque, traditionalist roman catholic, arm flailing autist, cartoon hyperbolic antithesis of the philosopher’s belated romantic schizophrenic inebriated prognathic pykie warrior ideal.)
I estimated 175 math IQ because I assumed the champion would be the top math mind of his entire U.S. birth cohort (one in several million) assuming these contests are efficient at recruiting all the top math talent in the U.S. but I don’t know if that’s a reasonable assumption
I know Bill Gates and Steve Balmer both got a perfect 800 on the old math SAT yet both finished far from #1 so that tells you how high the ceiling is.
Bruno would know more…
As for Tao, I have his IQ on hold since learning he took the old SAT multiple times and kept getting better because I want to know if it was the same questions each time or different versions of the old SAT
Puppy obviously never met a Math olympiad person.
I literally sat beside our countries math olympiad rep in math class.
I spent the whole 2 year cycle not doing any math homework because of ADD issues but this guy loved it.
It has 50% to do with math talent. The other 50% is being totally obsessed or even addicted to doing math. In this particular case, my friend wasn’t even autistic but if you love the subject you literally do it all day and you read college math books at age 12 or something just ‘for fun’.
My guess is there are lots of people that could do higher level math but find the topic boring eg. most girls/most boys.
If you leave out the autism people like bruno, who I would guess would always be the majority of the best math people, the neurotypicals will be quite random in math interest.
I think an outlier to the LSAT, and all standardized tests, is whether you studied before taking the test.
I know my intelligence is above average and I hardly ever studied until I studied in law school and for the bar.
I didn’t study much in high school, actually fell asleep for half the time I took the ACT the first time, and I made a 25. Retook it without studying but managed to stay awake the second time and got a 28.
I cannot remember my SAT scores but they were pretty good, too.
Twenty-two years later, I cold turkey took an LSAT practice test, and I made a 146. I watched six free lectures for the LSAT and studied what logic games were for a couple of hours and then took the real LSAT and got a 151.
This outlier is probably why they actually developed IQ tests and these calculations are just rough guestimates at best.
Hey, they are at least fun and a cheap way to calculate your IQ.
I feel like puppy was homeschooled. Am I right? Are you like that Evan O dorney guy?
Remember I kept linking videos to him talking and saying it was you hahaha.
Yes those were funny. My parents both worked so they never home schooled me. I think I could have benefited from homeschooling or rather unschooling
I grew up in Ireland and never once met a guy named ‘o dorney’. It must be a bastardisation of some other more common surname.
Nowadays I’d guess 50% of the UK’s math olympaid team is east asian or autistic or both.
I found a simple way to calculate IQ from the SAT –
IQ = Score ÷ 10
This is not perfect but I think it grasps the essences of a balanced scale where 160 is the appropriate ceiling.
