Well, that's the problem. Not many people ever learn real analytical thinking, and that's why the world is such a mess.
People jump to conclusions and then carve them in stone, accept the word of strangers and celebrities, and believe all sorts of superstitions unquestioningly and at times fanatically. And smart people mostly just rationalize their nonsense better than dumb people.
