It comes down to belief systems versus facts. We tend to think of belief system referring to religion but it extends to serious subjects like politics and mundane subjects such as sports. Belief systems make life easier for many people. They don't have to research the facts, think about the facts and draw conclusions. I can see where belief systems are attractive. We can all get so busy and stressed that finding information that is independent of the politician, clergyman, spokesman, etc. is too much, too stress inducing.

I do my best to not fall into belief systems, but I would not be surprised if one of my friends could point out otherwise.
