Welcome to LessWrong!
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.

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.

Harry Potter and the Methods of Rationality started as a side project of Eliezer’s and grew to be one of the most highly rated Harry Potter fanfictions of all time and an an excellent primer on rationality. Eliezer imagined an alternate-universe Harry Potter who grew up with loving adopted parents, one of them an Oxford scientist. He enters the wizarding world with a scientific and rationalist mindset.
