I qualify on two counts. Stanford Binet (1959) 134 and LSAT (1986) 96%. I probably qualify with me PSAT, but I don’t remember my score, but it was high. I just miss on the SAT (1969).
I’ve known a couple of Mensa members and interestingly they weren’t rocket scientists. They were weird little guys who were very smart, but also marginally successful in mediocre jobs. They were for lack of a better word misfits. Very bright, very nice misfits, but people who just didn’t quite fit into normal society.
I qualify for Mensa, but never bothered.
I know a guy who does Mensa get togethers, and my observation correlates with yours.
Most smart people are in jobs where they have lots of other very smart people to talk with.
Most Mensa people are smart but dysfunctional.
There are plenty of reasons for those misfits. Family biases and traditions can be major social roadblocks.
I’d expect most Mensa members to be quite nerdy, socially inept and a little “off” in areas of their lives. Personally, I don’t know if I’ve met or known any Mensa members, which are the kind I’d like to know.
In June/July of each year (when everyone moved up a notch) we'd always try to guess who the Harvard grads were. We found that the Harvard grads were the ones who could talk for 6 hours,non stop,about the uvula but if you handed them a pop up umbrella they were clueless.
