Definition
An "ingroup" is a social group to which a person psychologically identifies as being a member. It's the 'us' in 'us vs. them.' Think of it as your team, your tribe, or your family. Members of an ingroup often share common values, beliefs, or characteristics. Ingroups can provide a sense of belonging, identity, and support. However, they can also lead to bias and discrimination against outgroups. It's a fundamental aspect of social psychology.
