The Social Effects of an Awesome Solar Eclipse.

Astronomical events such as solar eclipses have played a transformative role in human social collectives as sources of collective wonder, inspiration, and reconciliation. Do celestial phenomena systematically shape individuals and their groups? Guided by scientific treatments of awe as an experience that helps individuals form into collectives, we used Twitter data ( = 2,891,611 users) to examine the social impact of a historic, awe-inspiring celestial event: the 2017 solar eclipse. Relative to individuals residing outside the eclipse's path, individuals inside it exhibited more awe and expressed less self-focused and more prosocial, affiliative, humble, and collective language (Study 1). Further, individuals who exhibited elevated awe surrounding the eclipse used more prosocial, affiliative, humble, and collective language relative to their preeclipse levels and relative to users who exhibited less awe (Study 2). These findings indicate that astronomical events may play a vital collective function by arousing awe and social tendencies that orient individuals toward their collectives.
