"Judgability" discriminates people who are open and knowable from those who are closed and enigmatic. The current study investigated this individual difference characteristic and its personality and behavioral correlates. Subjects (N = 164) were videotaped interacting with a partner of the opposite sex. They completed several personality measures, and each subject was described by 2 friends. Three indices--subject-peer agreement, peer-peer agreement, and peer-behavior agreement--formed a reliable composite index of judgability. The correlates of judgability included extraversion, agreeableness, conscientiousness, emotional stability, and, more generally, psychological adjustment.
