Research Summary: Controversy and Group Certainty Jointly Shape Everyday Moral Judgments

A research study utilizing data from online communities investigated how social information, specifically controversy and group certainty, influences everyday moral judgments regarding nuanced interpersonal dilemmas. The findings indicate that judgments are shaped by the perceived division of opinions and the confidence expressed by opposing sides, even without explicit arguments.

Why it matters

This research highlights how collective opinion and expressed confidence, rather than just rational arguments, can significantly influence individual judgment. Understanding these dynamics is crucial for anticipating public reactions to decisions and for developing communications strategies in contexts where moral or ethical considerations are prominent.

Key insights

• Everyday moral life involves disputes concerning families, relationships, work, money, and care, distinct from abstract ethical problems.
• People frequently encounter and are influenced by the judgments of others in these everyday moral situations.
• The study examined two social signals: 'controversy' (the division of community judgments) and 'group certainty' (the confidence expressed by each side).
• These signals were derived from 54,827 judgments on 135 dilemmas posted on Reddit's r/AmItheAsshole.
• A randomized experiment (N=2,159) presented these signals, individually or combined, to participants to assess their impact on moral judgments.
• Social information, even without revealing underlying arguments, shapes how individuals form judgments on interpersonal dilemmas.
