I learned the term Proportionality Bias while listening to Benjamen Walker's The Theory of Everything podcast . . . this logical fallacy explains the reason why there are so many conspiracy theories about the JFK assassination: our brain naturally believes that humongous world-shaking events need large, complex causes, and so it couldn't have simply been a lone gunman . . . while John Hinckley's unsuccessful assassination attempt of Ronald Reagan didn't cause as much turmoil-- because Reagan survived and made a prompt recovery-- and so it makes perfect sense that this was the work of a Jody-Foster-obsessed-wack-job . . . logically, we know that a tiny, random event can set a cascading sequence of actions and reactions that could conceivably set an entire city on fire . . . Mrs. Oleary's cow may have kicked over a lantern and started the Great Chicago Fire (or maybe not . . . it may have been started by a meteor shower . . . but either way, I think it proves the point) and the fact of the matter is that a cunning poltergeist did not inhabit your house in the night and wedge your car keys under the sofa, just to watch you scream and howl in the morning because you're going to be late to work . . . but it's much more fun to believe this than the boring, mundane truth.
