homingbrain: Also, strangely enough (not being a Harry Potter fan), I immensely enjoyed Harry Potter and the Methods of Rationality.

W4n: Written by a senior researcher at MIRI, it distills all the cogsci and pop psychology books you can think of (Kahneman, Freakonomics, Gladwell) into a smart, funny, engaging, book-length book-quality fanfic. ...

smaddox: because it set the bar (high) for all future fiction, especially when it comes to the insightful portrayal of the struggle between good and evil.

Joeri: Rationality is good, but I found Harry Potter and the Methods of Rationality to be a much more pleasant read about the same topics by the same author.

nitrogen: Provides an interesting introduction to some ways of thinking that may be new or surprising.

SonOfLilit: ...is one book that changed my life a lot more than I expected when picking it up. In many ways, it left me a different person.

pooriaazimi: I would say HPMoR is like Gödel Escher Bach, but slightly simpler and more approachable, and looks at stuff from a different angle. And Eliezer is an excellent writer, just like D. Hofstadter -- and his style is even more fun! If you're on HN, then you'll enjoy this book immensely.

rayalez: The most brilliant book I've read this year. I wish I'd read it 10 years ago.

sriku: Every single chapter is potentially mind blowing. The whole approach of trying to instruct rationality through such fiction is itself brilliant I think.
