For centuries, people have recognized the power of luck and have done whatever they could to try seizing it. Take knocking on wood, thought to date back to pagan rituals aimed at eliciting help from powerful tree gods. We still do it today, though few, if any, of us worship tree gods. So why do we pass this and other superstitions down from generation to generation? The answer lies in the power of luck.
To investigate scientifically why some people are consistently lucky and others aren't, I advertised in national periodicals for volunteers of both varieties. Four hundred men and women from all walks of life -- ages 18 to 84 -- responded.
Over a ten-year period, I interviewed these volunteers, asked them to complete diaries, personality questionnaires and IQ tests, and invited them to my laboratory for experiments. Lucky people, I found, get that way via some basic principles -- seizing chance opportunities; creating self-fulfilling prophecies through positive expectations; and adopting a resilient attitude that turns bad luck around.
