Existential isolation and I-sharing: Interpersonal and intergroup implications

I-sharing, or believing one has the same in-the-moment experience as another person, constitutes a specific way in which people may share reality. I-sharing research underscores its significance for interpersonal and intergroup outcomes. I-sharing fosters liking for people who differ from us in objective and sometimes important ways, and counteracts robust tendencies to favor ingroup members and dehumanize outgroup members. Research and theory indicate that existential isolation - feeling alone in one's experience - explains the potency of I-sharing, insofar as people with high levels of existential isolation are especially drawn to those with whom they have reason to believe they I-share. Recent findings are reviewed, followed by a discussion of the clinical implications of the work.
