Cure of not rationalizing: I feel confident that I'm not rationalizing. If I feel uncertain about whether or not I'm rationalizing then it can go either way and it's a sign I should be on guard, but if I don't feel any note of self-deception then that's normally pretty strong evidence that I'm not rationalizing. I'm not sure if this would be true for others; I've definitely seen people who claimed they felt that they were not rationalizing blatantly rationalizing.
