Lucky Charms Really Work Study shows they can affect performance By Kate Seamons, Newser Staff Posted Apr 29, 2010 11:07 AM CDT 7 comments Comments Superstitions can actually effect performance. (©1Happysnapper (photography)) (Newser) – Wearing your "lucky underwear" to every big meeting may mean you're a little weird—but not crazy. A new study shows that believing in good luck can actually have an impact on performance. Researchers told a group of putters that they were playing with a "lucky ball"—and the participants sank 6.4 out of 10 putts, about 2 more than those who weren't told their ball was special, reports the Wall Street Journal. But before you whip out those lucky undies and make a bet on the big game, be warned: Superstitions can't improve a situation whose outcome you have no control over.
