How can you improve your conception of rationality? Not by saying to yourself, “It is my duty to be rational.” By this you only enshrine your mistaken conception. Perhaps your conception of rationality is that it is rational to believe the words of the Great Teacher, and the Great Teacher says, “The sky is green,” and you look up at the sky and see blue. If you think: “It may look like the sky is blue, but rationality is to believe the words of the Great Teacher,” you lose a chance to discover your mistake. Do not ask whether it is “the Way” to do this or that. Ask whether the sky is blue or green. If you speak overmuch of the Way you will not attain it.~ Eliezer S. Yudkowsky from, http://yudkowsky.net/rational/virtues/
If you don’t think intentionally… If your ideas and beliefs don’t produce a working model of reality… well…
When an honest person discovers they are wrong, they stop being wrong or they stop being honest. It’s your choice.
