cognitive dissonance is an extremely interesting area, a view of the deepest parts of the human or sentient 'being'.
I would suggest that even some of those psychologists in the video clip you posted would have cognitive dissonance when confronted with the existence of the sub human psychopaths amongst us.......
One could go much much deeper down this path, with rational and logical thinking, and introducing anecdotal evidence, however it would probably be beyond the audience of Stage 1er's here.
