Explanation:

Attribution theory concerns the process by which individuals attempt to make sense of the cause-effect relationships in their life space. Events are seen as being either internally caused (that is, by the individual) or externally caused (that is, by other factors in the environment). In making causal attributions, people tend to focus on three factors: consensus, consistency, and distinctiveness.

Consensus: The extent to which you believe that the person being observed is behaving in a manner that is consistent with the behavior of his or her peers. High consensus exists when the person’s actions reflect or are similar to the actions of the group; low consensus exists when the person’s actions do not.
