Cognitive Dissonance is never a problem if you take the advice of the Red Queen; "I daresay you haven't had much practice,' said the Queen. 'When I was your age, I always did it for half-an-hour a day. Why, sometimes I've believed as many as six impossible things before breakfast."


I also find a helpful corollary is to abandon the term "Future Perfect" since it has recently been found not to be. (Thank you Douglas Adams)
