Are you superstitious? Good fortune is anyone’s for the taking—as long as you believe in it, that is.That’s what research published in the academic journal Psychological Science found after studying the phenomenon of “lucky charms” and how they impact successful people.QUIZ: Do You Feel Lucky?In a range of experiments, scientists at the University of Cologne, Germany, found that participants consistently outperformed competitors when they believed a lucky charm was present. In the first test, volunteers who were told they had a “lucky ball” in a golf putting game won more games than the others. In the second test, participants had to quickly place as many balls as possible into a slab with holes, and those who were told, “I’ll cross my fingers for you,” hailed more victory.In two more experiments, participants were allowed to bring lucky objects to tests involving memory and anagram word play. Half of the group were then asked to hand in the good luck charms before the exams, and those who were able to keep their cherished talismans performed better on both tests as a group.With results like that, even cynics may be inspired to reconsider the mystique of a rabbit’s foot. But experts say it’s less about the magic of hocus pocus, and more about the psychological power of the human mind. Those who carry and believe in lucky charms tend to set goals higher and enjoy boosts of confidence, which seems to result in enhanced performance and improved results. “Engaging in superstitious thoughts and behaviors may be one way to reach one’s top level of performance,” conclude the researchers in the article.MORE: Four Ways to Improve Your LuckAthletes are renowned for playing to superstition, from figure skater Michelle Kwan’s display of a Chinese charm necklace given to her by her grandmother at competitions, to Tiger Woods’ tradition of wearing a red shirt for Sunday tournaments.

“My friend Gia created a jewelry company called Social Anarchy awhile back. She gave me a gold rune necklace with the symbol for a spiritual warrior,” says Carmindy. “It represents courage and dedication, and a willingness to undergo your passage with compassion and total trust. The ancient Norse [Vikings] used to paint this symbol— an arrow pointing upward—on their shields before heading into battle. I’m always forging ahead and planning onward and upward, so this rune fit me. I wear it every day as a reminder to never give up on anything in life.”MORE: How Lucky Will You Be With Aging?

They also remind me of everything that is created by the universe, as seashells are unique, very special and beautiful in their own way. Each shell that I carry on me is one that I or my girls have found,” says Roy, of young daughters Ava and Tallulah.
