The Breakfast Club The Illusion (Illusion of Asymmetric Insight)
Studies have shown that individuals (and groups) significantly overestimate what they know about other people (or other groups). This is a subject that, if we’re honest with ourselves, is more prevalent than we’d like to believe, and helps add some depth to the concept of in-group/out-group bias.
The illusion of asymmetric insight makes it seem as though you know everyone else far better than they know you, and not only that, but you know them better than they know themselves. You believe the same thing about groups of which you are a member. As a whole, your group understands outsiders better than outsiders understand your group, and you understand the group better than its members know the group to which they belong.
