I'd recommend reading the academic books that CFAR lists, that will get you further than reading more blog posts, or more popular books.
That's missing the point of this question, which is "if I read all the academic books on CFAR's list, are there blog posts that contain things I will not have seen in the books?"
I've read a few of the Sequences (probably about 50-100 individual posts), but I've only occasionally come away with insights and perspectives that I hadn't already thought of or read elsewhere. I've read a bunch of the popular books on cognitive science and decision theory, including everything on the CFAR popular books list. I'm also about to start an undergrad in statistics with a minor (or possibly a second major) in philosophy.
My question is: Are there specific LW posts / Sequences / other rationalist blog posts that I should read that won't be covered by standard statistics and philosophy courses, or by the books on CFAR's popular reading lists?
