Less Wrong survey asked what is your favourite Less Wrong post. Slate Star Codex survey asks what is your favourite SSC post. Naturally, the next question is:

What are your favourite Overcomingbias posts? What posts did you find especially insightful or informative? What posts changed the way you think about something? What posts did you find thought-provoking even if you disagree with the ideas expressed in them (perhaps similarly to how Bryan Caplan thinks about Robin Hanson's ideas)? What good posts do you think should be better known? What posts would you recommend to others?
