According to new research from psychologist Heath Demaree, of Case Western Reserve University in Cleveland, Ohio, people who’ve experienced surprising outcomes in various situations — whether those outcomes were good or bad — are less likely to take risks in the future. In other words, it’s not whether you win or lose, but whether the outcome is expected. People appear to decrease their risk-taking levels after experiencing any surprising outcome — even positive ones.
“Surprising events are known to cause animals to stop, freeze, orient to the surprising stimulus and update their schemas of how the world works,” Demaree said. “Our recent research suggests that surprising events also cause people to temporarily reduce risk-taking.”
