This is what I describe as the egocentric approach to truth. You are no longer interested in reality because to do that you have to be pretty rigorous, you have to have evidence or do some experimentation. Rather, beliefs are part of your wardrobe. You’ve got a style and how dare anybody tell you that your style isn’t right. Ideology is seen as simply a matter of taste and as it’s not right to tell people that they’ve got bad taste, so it’s not right to tell them that their opinions are false. I’m afraid that the cast of mind of most people is the opposite of scientific.
