One common trait that math and science geniuses have


Yep, the height of creativity lies in math and science. I assume that most people don't understand this.
Intelligent people are also more willing/able to suspend their disbelief. A mean way to say it is they're more gullible. To learn a huge amount requires, at least initially, accepting absurdities as true, and working out the details for yourself later on.
It's no surprise that someone like Fischer fell into the trap of cult-like churches. Intelligent people look for patterns and logic even where there are none.
