Following axiom is easier to the brain. You do not need to think. All you need to is to accept what the "good guys" say. You do not need to maintain or update your own "axiom" - just use someone else's.

I think another reason why it happens, is related to what we are taught to do in debates. You look up the most approved or authoritative source, stick to it no matter what happens, and you will win the debate (because the source weigh the most). We don't need to care or question why the source is authoritative because it doesn't make you win the debate.
