No, you read the post of someone who knows a lot of people in Mensa. While
there are some well-adjusted people in the club, many of them are exceedingly
strange, much more so than other people with similar levels of intelligence.
The club attracts people who have nothing else going for them besides a high
IQ. Unfortunately, as a group they create the impression that intelligent
people are social misfits and eccentrics, when nothing could be further from
the case.
