Projection bias is a feature in human thinking in which one thinks that others have the same priority, attitude or belief that one harbours even if that is unlikely.

The concept of projection bias is different from that of psychological projection in which one thinks that others have a mental state one is unaware of having oneself.

A common example of projection bias is predicting that one's own views will stay the same over time, but that has been shown to be statistically unlikely.[1]
