Eating chocolate will stimulate your brain and make you feel good. Arming yourself with an understanding of statistics will do the same. There is a big difference, however, between these two activities. The euphoria… brought about by eating chocolate is short-lived, and it’s typically followed by feelings of guilt. In contrast, becoming armed with a knowledge of stats produces a lasting sense of satisfaction, especially when one uses this knowledge to fend off the unjustified claims made by crafty advertisers, self-serving politicians, and biased researchers.
