Welcome to Less Wrong

Less Wrong is…


In the past four decades, behavioral economists and cognitive psychologists have discovered many cognitive biases human brains fall prey to when thinking and deciding.

Less Wrong is an online community for people who want to apply the discovery of biases like the conjunction fallacy, the affect heuristic, and scope insensitivity in order to improve their own thinking.

Bayesian reasoning offers a way to improve on the native human reasoning style. Reasoning naively, we tend not to seek alternative explanations, and sometimes underrate the influence of prior probabilities in Bayes' theorem.

Less Wrong users aim to develop accurate predictive models of the world, and change their mind when they find evidence disconfirming those models, instead of being able to explain anything.
