Mensa is sadly a combination of positive and negative selection. Positive: by IQ. Negative: by having nothing more important to do than become a Mensa member.
If instead you took random people on the street and gave them IQ tests, and invited those who passed the IQ 130 bar to a meetup, it would be much more interesting than a typical Mensa meetup.
