People build a model of their world based on stimuli. You cannot be present everywhere so you trust other people to perceive things for you. That trust is often abused by injecting bias. And this is done to exert influence over people. Same trust is abused to certain extent by historians through revisionism. Same trust is abused by organized religion, where they control the rules of how you get favored by supreme beings. In some cases those rules are intrincated and arbitrary, like wasting your life building a pyramid, or entering a structure designated as temple every week, or believing other people belong to a better caste (where coincidentally the religious caste is usually at the top).
