And, as this is Less Wrong, I would add a seventh:
7) Others have thought of your question, found it challenging to let the question hang long enough to do research, failed to meet the challenge, let their biases choose their favorite answer to the question, and ran enough tests to produce a superficial veneer of data supporting their preferred answer. Your superior rationality might be enough to attempt an honest answer to the question, but you must also consider the possibility that the question is very hard to consider fairly. The prognosis: good, unless your Bayesian Jedi mind tricks are weak.
Voted up for clear thinking and relevance.
