Messaging about descriptive and injunctive norms can promote honesty in young children.

This research examined the effectiveness of using norms to promote honesty. Participants were Han Chinese children (N = 568, 50.4% male, 3.24 to 6.00 years, collected 2020-2022). Relative to children in a control condition, children in Study 1 were more likely to confess to having cheated in a game after being presented with a descriptive norm indicating that confessions are typical, or an injunctive norm indicating that most other children approve of confessing. Study 2 showed that this finding was not due to a methodological artifact, and Study 3 replicated the effect in a context in which the norm information was conveyed by someone other than the experimenter. The findings suggest that messages about social norms can influence children's honesty.
