But Kanazawa's schtick for this piece is: 'humans are designed/evolved to do X, so intelligent tend to be more Y in contrast'.

He mentions paranoia as a 'designed to be' trait. He directly links paranoia as an explanation for belief in God, and says the intelligent are more likely to be atheist. That pretty strongly suggests 'paranoia' is one of the ancestral norms from which he thinks the intelligent are now tending to deviate.
