This was sort of my experience with Mensa. Their three purposes supposedly are: 1. to identify and to foster human intelligence for the benefit of humanity; 2. to encourage research into the nature, characteristics, and uses of intelligence; 3. and to provide a stimulating intellectual and social environment for its members. It's not entirely clear to me how anything they do benefits humanity (1), the "nature, characteristics, and uses of intelligence" seem to revolve around games for them which is a pretty meaningless measure of any form of intelligence I care about (2) and while I'm not a member so I can't say whether it's stimulating to them, I can certainly say that all the materials I've come across from Mensa have soon bored me(3). So from where I sit, Mensa fails on two of their purposes, and only succeeds in their third because of a technicality in their wording.
