My opinion is that MENSA is for people whose main accomplishment in life is doing well on an IQ test. And who are insecure enough about it to pay someone else to validate that accomplishment. This opinion is shared by a number of people that I respect.

If you actually do something that requires using your brain, you should meet plenty of other people who have good brains and have done something with them. The "have done something" bit makes them into more interesting people to be around. Plus you don't have to pay for that privilege.

Random disclaimer. I am not a MENSA member. However my GRE scores qualify me for membership in most high IQ organizations, including MENSA.
