This research explores why people may show favoritism towards their own group and negative feelings towards other groups. It suggests that our biases often come from a desire to protect and bond with our own group, rather than from truly hating other groups. By looking at evidence from various fields like psychology and neuroscience, the researchers found that conflicts between groups are mainly fueled by love for one's own group rather than hatred for others. When tensions are high, outgroup hate might be more likely. The study also found that how we talk about groups can reveal our biases, with language showing more love for our own group than hate for others. Changes in group dynamics can lead to more negative language towards outgroups.
