<p dir="ltr">Ostracism is a prominent area of research within social psychology. Experiences of the ostracized have been well documented with little attention being given to sources of ostracism. Emerging research has begun to examine traits such as agreeableness in predicting ostracism experiences and has also highlighted motives in driving ostracism behavior. While promising, both areas require substantial expansion. More specifically, the newer work on personality has yet investigate how traits such as agreeableness may predict the use of ostracism. Furthermore, the existing research on ostracism motives is limited by measurement and has yet to be integrated as a psychological mechanism. The current research addresses these gaps by examining agreeableness as a predictor of ostracism behaviors and motives as an underlying psychological mechanism. </p>
