Abu's behavior is best described as an example of "pluralistic ignorance".
Pluralistic ignorance is a term that was created by Floyd H. Allport and Daniel Katz in the 1930s, portraying a circumstance where singular individuals from a gathering have an esteem or conviction that contrasts from what they trust the qualities or convictions of whatever remains of the gathering to be. This misinterpretation of others' qualities makes the gathering individuals act in manners that contrast from what they put stock in. Pluralistic ignorance is an efficient blunder in our estimation of the convictions of other individuals. We speculate the gathering individuals' convictions and standards in light of our perceptions, and our figure isn't right.
