Target adjustment and self-other agreement: Utilizing trait observability to disentangle judgeability and self-knowledge.

Are well-adjusted individuals good targets or accurate self-judges? Across two round-robin studies, the current research first demonstrates that well-adjusted individuals' personalities are viewed with greater distinctive self-other agreement by new acquaintances. Is this enhanced self-other agreement a function of greater judgeability, improving others' ability to form an accurate impression? Or is it a function of greater self-knowledge, having a more accurate impression about oneself? By examining the relationship between psychological adjustment and self-other agreement as a function of trait observability, it becomes clear that psychological adjustment fosters self-other agreement through judgeability more so than through self-knowledge. Specifically, well-adjusted individuals provide new acquaintances with greater information regarding their less observable traits, enhancing others' knowledge and thus distinctive self-other agreement. This effect was replicated with close informant-other agreement, indicating that the well-adjusted individual's tendency to make his or her less visible traits more accessible to others allows those who just met the target to agree better with people who know the target well. In sum, although well-adjusted individuals are in part good self-judges, it is their greater judgeability that seems most critical in enhancing self-other agreement in first impressions.
