I used to watch Jeopardy a lot. Alex Trebek (who has philosophy degrees from the University of Ottawa and the University of Toronto, and who was a noted philosophical debater in Canada before slumming into show business) never seemed to tire of announcing that MENSA members were miserable Jeopardy players, most getting bounced early on. I don't know what the connection is, I'm just passing on what Trebek observed over many years.
Jeopardy requires rapid recall of "trivial" information. Pattern recognition and problem solving are more often tested with IQ tests.
I disagree. In order to glean that "trivial" information, one had to be very well read in an eclectic mix of human interests. If the category was Shakespeare, and a single contestant answered eight question in a row of Shakespeare esoterica, well then that person must have read, understood, and retained the great bard's entire corpus. In short, Jeopardy winners weren't necessarily high IQ people, but they were well-rounded and very well-read people. They were in touch with the world.
Probably the greatest theoretical physicist in American history was Nobel Prize winner, Richard Feynman. The Cal Tech professor was also one of the greatest lecturers in American academia. His lectures were never dry cyphering drones. Rather Feynman interjected a plethora of reasons as to why subjects like theoretical calculus are important to humanity. His lectures were as much about the why as they were about the how. His IQ was 125.
