Those smarty-pants at Mensa

Somewhat off-topic, but those smarty-pants at Mensa have always irritated me more than a little. It took, however, a comment on Peter Hall’s site to really get me thinking about just how kooky they are.

Peter points to this Mensa page and says that with all the high IQs in their supposed target audience, is it really necessary that Mensa tell would-be applicants that 1 in 50 is the same as 2%?

Fair comment, and I would add to that something else further up the page:

Many people are surprised to learn they have an above average IQ.
Yes, given that half the population is by definition above average, I would guess …. oh, about half the population is “surprised”.
