Hmmm. It's better evidence that they want you to believe the claim is correct.
For example, I might cherry-pick evidence to suggest that anyone who gives me $1 is significantly less likely to be killed by a crocodile. I don't believe that myself, but it is to my advantage that you believe it, because then I am likely to get $1.

Much of rationality is pattern-matching. An article on lesswrong might point out a thing to look for. Noticing this thing changes your reasoning in some way. This essay is a list of things to look for. These things are all associated, but the reader should take care not to lump them together. Each dichotomy is distinct, and although the brain will tend to abstract them into some sort of yin/yang correlated mush, in reality they have a more complicated structure; some things may be similar, but if possible, try to focus on the complex interrelationships.
