There is a lot of conspiracy theory garbage floating around. On January 6, it took a violent turn. Five people died in a coup attempt at the U.S. Capitol, over obviously false claims of a stolen election. It is important to understand what causes this behavior in order to prevent future violence, and to prevent a future breakdown of liberal institutions. Over at Fortune, I explain that a little bit of basic price theory can improve our understanding:
If you think of irrationality as a consumer good, much like a car or a television, you can better understand why people sometimes say and do crazy things. Think of it like this: People buy more cars and televisions when they are cheap, and fewer when they are expensive.
This logic applies to conspiracy theories.
