I think people like to create false narratives when they don't have the knowledge or the ability to believe or explain something. I was reading a post about creationism and evolution the other day and I think that is a fine example. I am not of the opinion that the two things need to be mutually exclusive. Things evolve, there is scientific proof of it. However if you are raised to believe that one is true and the other is bad, it is hard to shake what is ingrained in you. To say, I know this to be true, but it goes against everything I have been raised to believe can create an extreme internal conflict. In some cases depending on the topic it can also alienate you from those you love or care about. It can disconnect you from your support system. Finally sometimes it can be pride and the fear of looking foolish. You can stubbornly hold onto something simply because you don't want to hear "I told you so".
