Previous research indicated that social categorization increased intergroup attitude. The current study extended research on social categorization by adopting the multiple personality categorization concept to explore whether it would alter inter-group attitudes toward Muslims and Buddhists.

Participants and procedure:
Study 1 examined multiple personality category perceptions among Buddhist and Muslim students living in the troubled southern provinces. Participants were 382 Thai Buddhist and Muslims students of mean age 20.15 years (SD = 1.01). They took the multiple personality categorization perception scale on outgroup perceived personality. Study 2 evaluated a mediated social identity complexity and a moderated personal value in association between multiple personality categori-zation and intergroup attitudes. Participants were 150 Thai Buddhists and Muslim students of mean age 20.31 years (SD = 0.94). They took the scales of multiple personality categorization: short version, intergroup attitudes, social identity complexity, and personal values. Descriptive statistics, independent t-tests and SEM were used to test hypotheses.

Study 1: Ten shared traits were identified (creative, smart, objective, talented, generous, kind, curious, resourceful, serious, skeptical) by both groups. This brought up awareness of similarity in shared personalities. Study 2: Multiple personality categorization and personal values were linked positively with intergroup attitudes. Personal values affected the links be-tween multiple personality categorization and intergroup attitudes. However, social identity complexity as a mediator was nonsignificant.

Muslim and Buddhist students were stimulated to explore their similarity in personality traits. Educators and policy makers may use the findings on personal values and multiple personality categorization to plan long-term sustainable cooperation between Buddhists and Muslims.
