It works, bitches.
"We invented the scientific method because we are naturally terrible at explaining our own experiences. Without the scientific method, there is no way to know what causes simple, everyday things like thunder. Every explanation is as good as another, and if an explanation becomes culturally bound and passed down, that becomes the official explanation for millennia. Our natural tendency is to confirm our assumptions, but science tries to disconfirm our assumptions one by one until the outline of the truth begins to form. Once we realized that approach generates results, we went from horses and tobacco enemas to mapping DNA and walking on the moon in a few generations."
