When people publicly rage about perceived injustices that don't affect them personally, we tend to assume this expression is rooted in altruism—a "disinterested and selfless concern for the well-being of others." But new research suggests that professing such third-party concern—what social scientists refer to as "moral outrage"—is often a function of self-interest, wielded to assuage feelings of personal culpability for societal harms or reinforce (to the self and others) one's own status as a Very Good Person.
