Outrage culture satisfies our urge for social solidarity.
Groups have social incentives to be outraged– expressing angershows your commitment to the values of your community. And media companies have financial incentives to rile people up– playing on your anger means more clicks and shares.
Outrage culture is the calamitization of the mundane. It allows us to form social bonds by combatting non-existent or exaggerated crises. By broadening the definition of calamities, we create new problems for which we need allies to solve. Furthermore, what we categorize as problems, and the solutions we propose, are indicators of our group affiliation.
