This post is sooo… derivative, but I cannot help myself. Good judgment is dependent on good information. It has never been so obvious how much we rely on good referees to determine what is good information. Most persuasion is based on filtering the information to the persuader’s advantage, but it has been rare in my lifetime to use the strategy of just hammering the lie.
It is easy to imagine that our paleo brains were rewarded by believing the chief. We both had skin in the game. So our still tribal brains believe things that are repeated over and over, even lies. Unfortunately, our information sources have gotten further and further from us so that our futures are not intertwined, except in an existential way. Our information networks have expanded and more critically selectively expanded.
