All religions are nothing more than scams preying on stupid people.
Do you believe what your psychologist said to you? You see that's pretty much the same guesswork as the neolithic shaman's explanations about harmful of beneficial spirits .
Science has not uncovered the inner workings of a human brain so I take everything with a truck load of salt what a psychologist has to say (I don't even consider it real science yet).
The scientific method relies on available information and not idiotic beliefs. It is constantly evolving, scrutinized and does not stuck with dogmas.
