Belief system Have you ever stopped to consider that half your belief system or more might be complete beass? Have you ever looked at people having diferent opinions from you and paused to think to yourself "maybe they're right about some things and I am wrong, because maybe all human beings have an evolutionary machanism that made our beliefs very selfish". Beyond selfishness you think that maybe your beliefs and the beliefs of others are limited because you don't think you have what it takes to be successfull and as a way of protection, you block off any idea which goes against yours and start seeing your beliefs as unmuttable truths.
