Do people believe good and bad luck can be washed away? Yes, according to an advanced online publication in the
Journal of Experimental Psychology that was co-authored by Rami Zwick, a University of California, Riverside marketing professor in the School of Business Administration.
Zwick, working with Alison Jing Xu of the University of Toronto, and Norbert Schwarz of the University of Michigan, designed two experiments that showed risk taking depends on whether participants recalled a past episode of good or bad luck and whether they washed their hands before engaging in a risky decision making task.
The experimental findings, in the paper "Washing Away Your (Good or Bad) Luck: Physical Cleansing Affects Risk-Taking Behavior," converge with anecdotal reports of superstitious practices, such as an athlete wearing the same unwashed shirt during a winning streak, and show that magical beliefs about luck have behavioral consequences.
Magical beliefs are exhibited, for example, by having confidence in one's ability to predict the outcome of a random event beyond the known probabilities if one can exert irrelevant control on the situation. For example, research has shown people are more confident they will have a winning scratch-off lottery ticket if they pick the ticket instead of being given one by a clerk.
