Nonverbal Decoding on Facebook: Applying the IPT-15 and the SSI to Personality Judgments

This study uses the lens model paradigm to explore whether two interpersonal sensitivity tests [i.e., Interpersonal Perception Task (IPT-15), Social Skills Inventory (SSI)] are associated with the accuracy of personality judgments made from Facebook (FB) profile pages. Target participants’ (N = 100) personality, self-monitoring, and FB honesty were self-reported, and the FB profile of each target was downloaded. Observers (N = 35) completed the IPT-15 and SSI and then estimated each profile owner’s personality from the profile pages. Observers’ scores on the IPT-15 were positively associated with the accuracy of estimates of targets’ extraversion and neuroticism. Observers’ SSI-ES scores were positively associated with the accuracy of estimates of targets’ agreeableness, conscientiousness, and openness. Characteristics of targets, such as self-monitoring, FB honesty, and overall FB use, also affected the accuracy of estimates. Results demonstrate that offline measures of sensitivity are associated with the accuracy of online personality judgments.
