Projection

Why don't they do what they say
Say what they mean
One thing leads to another
--The Fixx

Ever notice that people who accuse others of undesirable behavior often seem to practice that behavior themselves? For example, many cry that others aren't 'following science' while being completely uninterested in pursuing plausible rival hypotheses or data that are inconsistent with their worldviews.

These people may be projecting. Projection is the process of attributing negative perceptions about oneself to someone else. Doings so allows the projector to avoid avoid self-confrontation and dealing with a threat to one's ego.

Projection can be seen as a defensive routine for coping with cognitive dissonance.
