So, you passed those MENSA tests in Reader’s Digest when you were a kid. You’ve got a college degree, and always do better than half the contestants on Jeopardy. You can do the NYT crossword puzzle in 20 minutes (okay, you can finish it on the day you started it). Well, I bet you can’t name the 100 most common words in the English language in 5 minutes, or name the world’s 50 largest countries in 5 minutes either. “But those don’t really test intelligence” you’ll argue. So go ahead, try the not-so-fun Mensa Fun Test.
