Less Wrong

LessWrong (also written Less Wrong) is a community blog and forum focused on discussion of cognitive biases, philosophy, psychology, economics, rationality, and artificial intelligence, among other topics. It is associated with the rationalist community.

==Purpose== LessWrong describes itself as an online forum and community aimed at improving human reasoning, rationality, and decision-making, with the goal of helping its users hold more accurate beliefs and achieve their personal objectives. The best known posts of LessWrong are "The Sequences", a series of essays which aim to describe how to avoid the typical failure modes of human reasoning with the goal of improving decision-making and the evaluation of evidence. One suggestion is the use of Bayes' theorem as a decision-making tool. There is also a focus on psychological barriers that prevent good decision-making, including fear conditioning and cognitive biases, that have been studied by the psychologist Daniel Kahneman. LessWrong is also concerned with artificial intelligence, transhumanism, existential threats, and the singularity.
