Feynman's measured IQ was 123, not 137. And we already know that IQ tests do not measure vitally important aspects of cognition -- in Feynman's case especially, he was quite strong in those aspects while being weak in the aspects measured. (At least, I know that. What the rest of you know is less certain.)

You don't even know that. This sort of thing is why no one here likes you. Here, let me provide some more details about that IQ score you put such weight on as a criticism. To quote a previous comment of mine on this topic:

• Feynman was younger than 15 when he took it, and very near this factoid in Gleick's bio, he recounts Feynman asking about very basic algebra (2^x=4) and wondering why anything found it hard
• the IQ is mentioned immediately before the section on 'grammar school', or middle school, implying that the 'school IQ test' was done well before he entered high school, putting him at much younger than 15. (15 is important because Feynman had mastered calculus by age 15, Gleick says, so he wouldn't be asking his father why algebra is useful at age >15.)
• Given that Feynman was born in 1918, this implies the IQ test was done around 1930 or earlier. Given that it was done by the New York City school district, this implies also that it was one of the 'ratio' based IQ tests - utterly outdated and incorrect by modern standards.
• Finally, it's well known that IQ tests are very unreliable in childhood; kids can easily bounce around compared to their stable adult scores.

So, it was a bad test, which even under ideal circumstances is unreliable & prone to error, and administered in a mass fashion and likely not by a genuine psychometrician.
