Zusammenfassung/Abstract:	Objective: This study examined personality expression, impression formation, and the consensus and accuracy of zero-acquaintance personality judgments that were based on people's Instagram accounts. Method: Self- and informant reports of the Big Five personality traits, self-esteem, and narcissism were collected for 102 Instagram users. Screenshots were taken of Instagram users' profiles, including up to the 102 latest available Instagram posts. A number of Instagram cues were objectively retrieved, counted, and rated by independent trained cue coders from the screenshots. 100 unacquainted observers then judged the Big Five traits, self-esteem, and narcissism on the basis of Instagram screenshots only. Results: We identified Instagram account characteristics that were associated with users' personality traits (measured with self-reports, informant reports, and self-informant composites) and observers' zero-acquaintance personality judgments. Personality judgments that were based on Instagram accounts demonstrated consensus and significantly converged with Instagram users' Big Five traits, self-esteem, and narcissism across all three personality criteria. Averaged-observer accuracy correlations for self-informant composite scores ranged from r = .44 (p < .001) for extraversion to r = .25 (p = .013) for conscientiousness. Conclusions: Our findings provide insight into cue processes of online self-portrayal and impression formation on Instagram and the level of zero-acquaintance accuracy.
