An intergroup perspective in the legal context highlights the influence of group membership on the interaction between authorities and citizens. Social identity influences communication both in the field (e.g., police–civilian) and in the courtroom (e.g., juror deliberation). The research in the law enforcement context addresses trust in police officers, the communication accommodation between police and civilians, sociodemographic stereotypes impacting police–civilian encounters, the role of police media portrayals, and its influence on intergroup exchanges between police and civilians. Juries are inextricably influenced by group membership cues (e.g., race and gender), and differentiate those in the ingroup over the outgroup. The impact of stereotypes and intergroup bias is evident in the literature on jury decisions and the severity of punitive sentencing. These and other factors make the intergroup nature of the legal context significant, and they determine the interconnection between the parties involved. Specifically, the social identity approach brings focus to the biases, attributions, and overall evaluations of the perceived outgroup. The research indicates that diversity is necessary to alleviate the intergroup mindset, thereby encouraging a more interindividual viewpoint of those outgroup members.
