I know I'm long-winded, and apologize. I'm busy, and as Pascal said, "This letter is too long, because I lacked the time to make it shorter."

I like metaphors. They're useful for illuminating things. I can go on and on about how failing the IAT doesn't make you racist because you can hold beliefs on two different levels, or I can say "It's like running away from a haunted house even if you don't believe in ghosts." I haven't formalized my intuitions on which metaphors are or aren't good yet, but I should.

IV seems plausible, but I can't think of exactly how. Sounds like it deserves its own top-level post.
