You are deciding about two movies, your girlfriend wants to see the most boring one so after the cinema, you think it was a good movie and cool after all.
Liberal: But you blamed everything that happened during the Bush Administration on Clinton. How is that any different?
Conservative: I guess I'm engaging in some cognitive dissonance.
esp. used by the American liberal left when encountering something they disagree with or anything which does not reinforce their cosy ideology without ambiguity and/or ambivelance.
Of course it is believed true that the aural perception and identification of cognitive dissonance is identical on all possible fronts and viewpoints and corresponds (with knowing infallability) between the listener and whichever poltical/cultural hack has taken to the soapbox at any given time.
"Surely that can't be true, he's a Democrat, he's America's first black President, Reverend Jesse James cried tears of joy on national T.V at his inauguration for christ sake! I must say I'm getting lot of cognitive dissonance right now"
"Well I assure you it is harmonically correct to more than a select few of musically trained ears, and please, stop calling me shirley!"
Xbox fanboy: Uhhh...Okay. Cognitive dissonance. I'll just go back to playing Halo 3.
