Should we trust our first impressions of people?
Do people have insight into the validity of their first impressions or accuracy awareness? Across two large interactive round-robins, those who reported having formed a more accurate impression of a specific target had (a) a more distinctive realistically accurate impression, accurately perceiving the target’s unique personality characteristics as described by the target’s self-, parent-, and peer-reports, and (b) a more normatively accurate impression, perceiving the target to be similar to what people generally tend to be like. Specifically, if a perceiver reported forming a more valid impression of a specific target, he or she had in fact formed a more realistically accurate impression of that target for all but the highest impression validity levels. In contrast, people who generally reported more valid impressions were not actually more accurate in general. In sum, people are aware of when and for whom their first impressions are more realistically accurate.
