He's saying that, on average, a high IQ person does not find Mensa valuable or interesting and so does not bother to join.

Whereas, someone who is lonely, searching community, depressed, etc and _also_ has a high IQ would be more likely to apply and join.

The fact that you happen to be normal, healthy, and a Mensa member isn't particular important when speculating about the possible selection bias. Although, we are just speculating.

Yeah, I was well aware what the implication was :) I was just stirring the pot really...

It's always interesting to read the general sentiment towards Mensa members — implying they join out of "loneliness" or "depression" is a hilariously unfounded assumption. I agree that Mensa is fairly pointless overall, but in my experience, its members are generally pretty representative of the general population.
