Recent research has highlighted the relevance of intellectual humility to politics. Among a U.S. sample (N = 852), we examined self-reported sociopolitical intellectual humility (SIH), a nonthreatening awareness of the fallibility of one’s views about topics central to society and politics. SIH was associated with being less likely to dislike/avoid political discussion, and with more political tolerance, less social dominance orientation, and more values and behavioral intentions focused on social equality, even when controlling political orientation and other relevant factors. SIH was also associated with more positive and less negative views of an individual expressing a political viewpoint. Further, SIH moderated the extent to which initial agreement with a political statement resulted in opinion change on the basis of hearing another person's arguments on the topic. These findings may point to ways SIH is relevant to people's attitudes toward others in society.
