Intelligence is useful in almost any job and is a valuable predictor of
success in most jobs. However, joining a social club based on IQ says other
things about a person that are not necessarily positive. And as I've said,
anyone who has a good knowledge of Mensa might think twice about hiring
someone in the club.

Sour grapes.

Nope, just the distillation of discussions I've had with club members on the
topic. Mentioning Mensa membership is like mentioning IQ on a resume, only
worse, because it speaks not merely of intelligence but also of socialization
(or lack thereof). Someone who thinks enough about his IQ score to join a
club based on that is likely to be pretty preoccupied with it, which may not
be a good thing.
