Whether revealed in a post on social media, a short video on TikTok, or the latest piece of news on Fox or NBC, it is hard to ignore political divisions in the U.S. We ... conducted a survey of over 2,400 Republicans and Democrats in the lead-up to the 2020 presidential elections. We included questions about each person's moral and sociopolitical attitudes and beliefs. We found considerable similarity in their moral and political attitudes. At least 75% of responses overlapped. Both groups endorsed the importance of considering how fair or harmful their actions are for others, and they both believed that upholding democracy and finding bipartisan solutions is important for the U.S. In a series of subsequent experiments involving more than 4,400 participants, we presented our findings to people who had not participated in the survey. Participants all saw the same findings, but they were randomly assigned to see the information described in different ways. For some participants, our results were described as showing small differences between Democrats and Republicans, whereas for others they were described as showing a high degree of similarity between the two groups. When findings were described as showing similarities, participants thought that their political opponents had attitudes and beliefs that were more similar to their own group. They were more willing to find common ground with their political opponents on major social issues like gun control and abortion. Focusing on group differences might inadvertently contribute to political tension.
