An occasion for unselfing: Beautiful nature leads to prosociality

• The tendency to perceive natural beauty positively predicted trait prosociality.
• Beautiful compared to less beautiful nature lead to greater helping behaviors.
• More beautiful nature and generosity is mediated by positive emotions.
• Beautiful nature promotes greater prosociality for those who perceive natural beauty.

Past studies have documented interpersonal benefits of natural environments. Across four studies, we tested the hypothesis that exposure to more beautiful nature, relative to less beautiful nature, increases prosocial behavior. Study 1 yielded correlational evidence indicating that participants prone to perceiving natural beauty reported greater prosocial tendencies, as measured by agreeableness, perspective taking, and empathy. In Studies 2 and 3, exposure to more beautiful images of nature (versus less beautiful images of nature) led participants to be more generous and trusting. In Study 4, exposure to more beautiful (versus less beautiful) plants in the laboratory room led participants to exhibit increased helping behavior. Across studies, we provide evidence that positive emotions and tendencies to perceive natural beauty mediate and moderate the association between beauty and prosociality. The current studies extend past research by demonstrating the unique prosocial benefits of beautiful nature.
