Humans Evolving to Become Less Intelligent?

Gerald Crabtree, a geneticist at Stanford University, suggests that humans are evolving to become less intelligent. Crabtree asserts that the safer life gets for humans, the less important it is for us to have good judgment for survival and mating.

Thousands of years ago, human idiots were much more likely to be removed from the gene pool (i.e., die) as a result of their lack of intelligence and judgment. Nowadays, it’s rare for someone to die because they were unable to outwit a predator.
