A new study by an interdisciplinary team of researchers across six different countries has found that affective polarization, or the tendency to dislike people who belong to opposing political parties while favoring people from their own political party, is a global bias—not just an American one. The research further indicates that the dislike grows stronger when two people think about political issues the same way but come away with different beliefs about those issues. The work is published in the journal Personality and Social Psychology Bulletin.
