What is the pitfall of believe systems?

Believe means that you unwilling to admit what you do not know as "I do not know", what ever you do not know is what you believe. If you believe, what it does to you is, it will give you confidence. Confidence without clarity is a disaster. Believing in God, believing in your self, believing in anything is just a "b" word. It means you are bullshitting yourself self about something you do not know.

People who believe something often think they are superior to others. All that happens the moment you believe something is that your stupidity acquires confidence.
