In the words of Neal Stephenson, "we are all susceptible to the pull of viral ideas. Like mass hysteria. Or a tune that gets into your head that you keep humming all day until you spread it to someone else. Jokes. Urban legends. Crackpot religions. Marxism. No matter how smart we get, there is always this deep irrational part that makes us potential hosts for self-replicating information." This speaks true to today's topic. Humans seem to have an urge to be in constant chaos; sometimes to the point where they will intentionally create scenarios to cause it. Take a ride with us today as we go over some cases where mass hysteria has gripped society. Its usually not until it passes that we begin to think rationally and question why it affected us so much. This is Temporary Insanity.
