For quite some time, research has indicated that negative emotions are more powerful than positive ones, Cohn says. For example, studies show that people don’t have equal reactions to winning $3 and losing $3, he says. The loss tends to have a stronger effect than the gain.

Negative emotions might edge out positive emotions in the moment, says Cohn, because they’re telling you to find a problem and fix it. By contrast, positive emotions appear to win out over time because they let you build on what you have, a finding reinforced by Cohn’s recent study.

“We found that as positive emotions go up, there comes a point where negative emotions no longer have a significant negative impact on building resources or changing life satisfaction,” Cohn says. “Positive emotions won’t protect you from feeling bad about things, nor should they. But over time, they can protect you from the consequences of negative emotions.”

This may not be true for people with depression or other serious disorders, although they do show benefits when positive emotions are added to conventional psychotherapy, Cohn notes.
