About Less Wrong

Interested in improving your reasoning and decision-making skills? Then you've come to the right place.

Less Wrong is a large, active website for people who try to think rationally. To get a quick idea of why rationality is important and how to develop it, try reading Your Intuitions Are Not Magic, The Cognitive Science of Rationality, or What I've Learned From Less Wrong.

Here's a selection of other posts from the extensive Less Wrong archives that might appeal to you:

The Less Wrong Community

Less Wrong makes heavy use of previously introduced topics for leverage, so you may need to consult the Concepts and Jargon pages on the Less Wrong Wiki. You can also do keyword searches of past posts using the search tool near the top right corner of every page.

Unlike some skeptics, Less Wrong users don't automatically reject odd ideas and sometimes endorse them. Odd ideas users have been known to espouse include transhumanism, cryonics, and caution regarding AI research.

To meet other rationality enthusiasts in meatspace, find a nearby Less Wrong meetup group or start a new one.
