All this study says is that there's a correlation of Mensa membership to a higher likelihood of certain disorders. It does _NOT_ establish any causal links, or even that Mensa membership is representative of the much much larger population of people who can get a 98th percentile score on an IQ test. Perhaps disorders cause people to join Mensa? Who knows.

Just because correlation doesn't imply causation doesn't mean you should negate it causation. You need correlation to exist to even have causation so correlation is evidence for causation.
