Want to try an experiment? Part 1: Get yourself a crowd of willing co-experimenters — about 20 to 30 — and tell them that you’re going to ask them a trivia question. Tell them you’re going to read the question to them and when you count to three, everyone should shout out their answer at the same time. They should all shout out a guess — even if they have no clue what the answer is. Just yell it out. Then ask the group some really esoteric question — one that most people are unlikely to know but that isn’t so out there that it’s unanswerable.
