This study examined differences in personality between fraternity- and sorority-affiliated college students and unaffiliated college students. A 20-item online survey was completed by 613 undergraduates (51% fraternity- and sorority-affiliated) measuring the Big Five personality factors. Analyses were conducted using independent samples t-tests to compare personalities of fraternity- and sorority-affiliated students to unaffiliated students. Fraternity and sorority members scored higher on measures of extraversion, measures of conscientiousness, and lower on measurers of neuroticism than nonmembers.
