That's very interesting but I think that some people can explain their creative process. Bruce Adolphe is musician who hosts a piano puzzler radio show. If you are a classical music buff I highly recommend it. He takes well known songs or pieces of music and then rewrites them in the style of an old composer. (The challenge is find the popular song buried within and figure out which composer it is in the style of). Anyways in each of his segments, he explains exactly what he is doing to imitate the style of that composer and how he incorporated the popular song into it.
A lot of Less Wrong frames becoming more rational in terms of correcting biases. When Scott Alexander is asked how he does it, he doesn't seem to actually have an answer-- if I recall correctly, he's just said that all he's got in his life is his job, his girlfriend, and his blog, which doesn't begin to explain his remarkable flow of interesting posts.
It's a good thing to have fewer and weaker biases, but it's better if de-biasing can be applied to new ideas which have a good chance of paying off.
Is there LW material about creativity that I'm not remembering? Any recommendations for information about creativity elsewhere? I'm especially interested in material which you've seen help you or other people become more creative, as distinct from material which has been plausible and/or fun to read.
Edited to add: While I think this is a generally applicable topic, I also have a local interest. I'm fond of LW, but it seems to be in a doldrums, and at least part of the cause is a lack of interesting new material.
