The road to wisdom?
-- Well, it's plain
and simple to express:
and err again
- Piet Hein
Hence the name LessWrong. We might never attain perfect understanding of the world, but we can at least strive to become less and less wrong each day.
We are a community dedicated to improving our reasoning and decision-making. We seek to hold true beliefs and to be effective at accomplishing our goals. More generally, we work to develop and practice the art of human rationality.
To that end, LessWrong is a place to 1) develop and train rationality, and 2) apply one’s rationality to real-world problems.
The fastest way to get started is with our selection of highlighted posts.
To get a feel for what LessWrong is about, check out our Concepts page, or view this selection of LessWrong posts which might appeal to you:

If LessWrong seems like a place for you, we encourage you to become familiar with LessWrong’s philosophical foundations. Our core readings can be be found on the Library page.
We especially recommend:
- Rationality: From AI to Zombies by Eliezer Yudkowsky (or Harry Potter and the Methods of Rationality by the same author, which covers similar ground in narrative form)
- The Codex by Scott Alexander

Rationality is a term which can have different meanings to different people. On LessWrong, we mean something like the following:
- Rationality is thinking in ways which systematically arrive at truth.
- Rationality is thinking in ways which cause you to systematically achieve your goals.
- Rationality is trying to do better on purpose.
- Rationality is reasoning well even in the face of massive uncertainty.
- Rationality is making good decisions even when it’s hard.
- Rationality is being self-aware, understanding how your own mind works, and applying this knowledge to thinking better.
