Prior studies have already found differences between leftists and rightists in presenting anti-social preferences. Political extremism was also found closely correlated with anti-social events. However, studies about the ideological difference in antisocial preferences against outgroups and the interactive effect of ideology and political extremism on anti-social preferences against outgroups are required for a better understanding of real-life violent political events. In a large experimental study (n = 769), I examined two hypotheses: (1) Rightists have higher anti-social preferences against outgroup members than leftists; (2) Levels of political extremity may moderate the relationship between ideology and anti-social preferences against outgroup members. Participants were asked to play the Joy of Destruction game with members of different ideology, same ideology, different nationality, and same nationality from them respectively. After the game, participants were asked about their political orientation and levels of political extremity. The results showed rightists have higher anti-social preferences against national outgroups than leftists; no significant difference in anti-social preferences against ideological outgroups was found between rightists and leftists. The level of political extremity was found not significant in moderating the relationship between ideology and anti-social behaviors against both ideological outgroups and national outgroups. These findings filled the gap for us to understand the ideological differences in anti-social preference against outgroups and they may stimulate future research.Show less
