Ingroups and Outgroups

This week in class our teacher told us to prepare for an activity. He separated the class in who was wearing black clothing and who was not wearing black clothing. I was in the group wearing black and our teacher then told us to write reasons why our group thinks the other side of the class is not wearing black. As soon as both groups started writing reasons, everyone all of the sudden just started to judge our other classmates in very bizarre ways. During this activity no one really knew why we were doing it but after our teacher started to explain how we are in ingroups all of our lives and how we judge other crowds (outgroups). Just because our teacher put us in a group just because we were all wearing black, we all felt a connection and started to trust each other and just randomly judge the outgroup because they were different than us. Our teacher made us realize how we do this everyday in our lives and don't even realize it. Everyone is apart of an ingroup and have judged another person just because they talk to different people. So we should all try to realize how we think of others just because they are apart of another group.
