Racial discrimination is back as a hot topic. Although studies documented that racial inequality negatively influences racial minorities, the relationship between perceived racial discrimination and aggression is unclear. Therefore, this study aims to explore the impact of perceived racial discrimination on aggression in Malaysia. A total of 136 adults responded to an online survey consisting of the Brief Perceived Ethnic Discrimination Questionnaire-Community Version (Brief PEDQ-CV) and Aggression Questionnaire 12 (AQ-12). Correlation analysis found positive relationships between subscales of perceived racial discrimination (Exclusion, Workplace Discrimination/Discrimination at school, Stigmatisation, Threat and Harassment, & Police) as well as aggression (Physical Aggression, Verbal Aggression, Anger, & Hostility). The Police subscale, however, was only associated with Physical Aggression. Gender differences were found in Physical Aggression, with males scoring higher than females. Multiple regression analyses showed that Exclusion has impact on both Anger and Hostility. The findings of this study contribute to relevant literature by showing that people become angry and hostile when they are being racially excluded. The results also highlight the importance of racial equality in individual well-beings in addition to creating awareness of racial discrimination in Malaysia.
