Before patting yourself on the back for resisting that cookie or kicking yourself for giving in to temptation, look around. A new University of Georgia study has revealed that self-control — or the lack thereof — is contagious.

In a just-published series of studies involving hundreds of volunteers, researchers have found that watching or even thinking about someone with good self-control makes others more likely exert self-control. The researchers found that the opposite holds, too, so that people with bad self-control influence others negatively. The effect is so powerful, in fact, that seeing the name of someone with good or bad self-control flashing on a screen for just 10 milliseconds changed the behavior of volunteers.

“The take home message of this study is that picking social influences that are positive can improve your self-control,” said lead author Michelle vanDellen, a visiting assistant professor in the UGA department of psychology. “And by exhibiting self-control, you’re helping others around you do the same.”
