Actions such as knocking on wood, spitting or throwing salt, are common practice even among people who aren’t particularly superstitious.
University of Chicago Booth School of Business researchers discovered these superstitions actually do “reverse” perceived bad fortune.
People believe that negative outcomes are especially likely after a jinx. If someone says, “No one I know will ever get into a car accident,” for example, it often feels that a car accident is likely to occur.
But people’s elevated concerns after tempting fate can be eliminated if they engage in a ritual to undo that bad luck.
Noting that many of the most common rituals for undoing bad luck — knocking on wood, spitting, and throwing salt — all seem to involve movements that exert force away from a person, researchers set out to test whether the avoidant nature of the action is key for reducing the negative expectations and heightened concern generated by tempting fate.
“Our findings suggest that not all actions to undo a jinx are equally effective. Instead, we find that avoidant actions that exert force away from one’s representation of self are especially effective for reducing the anticipated negative consequences following a jinx,” said researcher Jane Risen, Ph.D.
Risen conducts research in the areas of judgment and decision-making, intuitive belief formation, magical thinking, stereotyping and managing emotion.
“Engaging in an avoidant action seems to create the sense that the bad luck is being pushed away,” Risen says.
Titled “Reversing One’s Fortune by Pushing Away Bad Luck,” the study was published in the Journal of Experimental Psychology: General.
In five separate experiments, researchers had participants either tempt fate or not and then engage in an action that was either avoidant or not.
The avoidant actions included those that were superstitious — like knocking on wood — or non-superstitious — like throwing a ball.
They found that those who knocked down (away from themselves) or threw a ball believed that a jinxed negative outcome was less likely than participants who knocked up (toward themselves) or held a ball.
In addition, the researchers found that engaging in an avoidant action had its effect by leading people to have a less vivid mental image of the negative event.
