Savoring—an emotion-regulation strategy that involves deliberately upregulating positive affect—has many benefits, but what enhances savoring in the present moment? Drawing from life-history theory, affective and developmental science, and social-psychological frameworks, we examined the idea that perceptions of uncertainty––perceiving the world as random and unpredictable––enhance subsequent savoring. In a large experience-sampling study (Study 1, N = 6,680), we found that individuals who perceived more uncertainty showed increases in subsequent savoring in their daily lives. In a preregistered experiment (Study 2, N = 397), individuals who watched a film that induced uncertainty (vs. order or a control condition) subsequently reported higher savoring intentions. Finally, in a field experiment on a busy urban street (Study 3, N = 201), we found that passersby who received fliers that induced uncertainty (vs. order) subsequently engaged in more savoring behavior by stopping to smell a bouquet of roses. These findings from three studies with diverse samples and methodologies underscore an upside to the specter of uncertainty: it can cause people to savor the positives of the present.
