THE PRATFALL INSTITUTE — I'm not proud to admit this, but I love fail videos. You know, the ones where someone falls down on a patch of ice holding a birthday cake or manages to inadvertently do a double backflip with a quarter rotation off a trampoline and into some bushes. Stop judging me, I said I'm not proud of it. Turns out there is a word for why we laugh at these things, and that word is schadenfreude. "There is part of our brain that gets turned on when we are rewarded at someone else's expense," explains Dr. Joseph A. Shrand in Psychology Today. "Schadenfreude is when we laugh at someone else's misfortune. Schadenfreude comes from the two German words, Schaden and Freude, harm and joy. We've all done it, even if we are not proud of it."
