My IQ was measured at 156 by MENSA a few years ago (I had a very low self esteem and wanted to know if my perceived academic failure up to that point was down to stupidity). I thought I'd join the society for something to do (I have a limited social life). I went out for a few meals and met some nice people. However, I had to consider what the point of the society was, other than to say 'I'm in MENSA', so I decided to leave. May be if all the smart people banded together to make the world a better place it would be worthwhile, but it just seems to be more for socialising.
