Out-group bias refers to the tendency of individuals to favor their own group (the in-group) over other groups (the out-groups). This bias leads to more positive attitudes, beliefs, and behaviors towards members of the in-group compared to members of the out-group, even when the groups are arbitrarily defined. This term is particularly relevant in the context of 2.3 Human Behavior Is Partially Predictable, as it highlights how our tendency to categorize people into in-groups and out-groups can shape our perceptions and behaviors in predictable ways.
