Liking Predicts Judgments of Authenticity in Real-Time Interactions More Robustly Than Personality States or Affect

We conducted three studies involving small group interactions ( N = 622) that examined whether Big Five personality states, affect, and/or liking predict judgments of others’ authenticity. Study 1 ( n = 119) revealed that neither self-rated personality states nor affect predicted other-rated authenticity. Instead, other-rated liking was the only predictor of other-rated authenticity. Study 2 ( n = 281) revealed that other-rated personality states and affect were significant predictors of other-rated authenticity, but other-rated liking was a more important factor in predicting other-rated authenticity than specific behaviors or affect. Based on these results, Study 3 ( n = 222) examined whether experimental manipulation of likability had a causal effect on other-ratings of authenticity. Likable actors were indeed judged as more authentic. Together, this suggests that we judge people we like as more authentic and that likability may be more important than the “objective” content of behavior.
