The ability to choose an evidence-based psychotherapy on the base of scientific knowledge has been a negligible factor in the evolution of the human brain. One could argue that empirical science itself fosters a style of thinking that is counter-intuitive for many of us.
Personally I believe that the human way of trying to identify causal relations in a chaotic universe is the main reason of the evolution our kind has taken in the last few thousand years. But our susceptibility to see causal relations can also be a big problem.
