Not All Seniors Are Equal: Interpreting Trait Scores of the College Graduate

According to their findings, as individuals age from about 18 to about 30, their scores on the traits of Neuroticism, Extraversion, and Openness tend to decrease, while scores on Agreeableness and Conscientiousness tend to increase.
