Over the last few decades, new experiments have changed science's picture of the way we think — how we succeed or fail to obtain the truth and achieve our goals. The heuristics and biases program, in cognitive psychology, has exposed dozens of major flaws in human reasoning. Social psychology has learned about how groups succeed or fail. Behavioral economists have measured the way humans decide against models of optimal decision-makers, and discovered that we often decide suboptimally.

Less Wrong is a site for people who want to apply these findings to their own thinking.

This wiki is a companion for the community blog Less Wrong. Our criterion for "notability": a concept needs to be discussed in at least one promoted article, and later be referenced by another (possibly unpromoted) article. If you want to write about something that isn't "notable" yet, do it on the blog!
