On this week's podcast, we talk about the social identity theory of in-groups and out-groups. In certain situations, we end up having in-group bias to the point of discriminating against, and downplaying the importance of out-groups or groups of people who we don't identify with. Whether we're part of many in-groups or in someone's out-group, in-group bias can be reduced to begin a chain reaction of understanding how it feels to identify with many different groups.
