To fully understand the concepts of social exclusion, social group formation and social identity, I created a short Google survey to test these processes in a real world setting. This survey is available to view on the Other Materials Page.
This survey question was centered around the two different theories of social groups. The first option (blue) refers to the Social Identification model. The second option (red) refers to the Social Cohesion model. The results of this question indicated that maybe the social cohesion model is more accurate. However, recent studies show that the opposite is true. Choosing our groups based on how we identify ourselves is often an unconscious decision and thus, we may consciously feel as though we would choose a friend based on personality.
One of the main reasons for social exclusion can be based on their outward appearance and/or demeanor. As humans we tend to unconsciously judge others based on how they outwardly act before really getting to know them.
