Why would being a good problem solver mean you were less good at the ordinary more instinctive behavior?

General intelligence evolved to solve evolutionarily novel problems, so intelligent people are more likely to acquire and espouse evolutionarily novel preferences and values. They are more likely to recognize and develop tastes for things that our ancestors did not have 100,000 years ago. For example, more intelligent people are more likely to be left-wing liberals because our ancestors were “conservative” by the contemporary American definition—they only cared about the well-being of their friends and family. They are more likely to be atheist because the preferred theory in evolutionary psychology is that humans are designed to believe in God.

Really?

Humans appear to be designed to be paranoid; they are designed to see intentional agents behind natural phenomena. This is because making the mistake of thinking that a natural event has an intentional agent behind it is less potentially costly than being oblivious and thinking that an intentional event, like someone trying to kill you, has a coincidental cause. The paranoid outlive the oblivious. Belief in God may be a consequence of this tendency. Intelligent people are more likely to be nocturnal because humans are designed to wake up when the sun comes up and go to sleep when the sun goes down. They are more likely to be homosexual, because humans are evolutionarily designed to reproduce heterosexually. They are more likely to enjoy instrumental music because music in its evolutionary origin was vocal, and they are more likely to consume alcohol, cigarettes and drugs because all of these substances are evolutionarily novel.
