The EA handbook is an introduction to some of the core concepts in effective altruism.

If you’re new to effective altruism, it should give you an overview of the key ideas and problems that we’ve found so far. But if you have already engaged with effective altruism, there should be some new insights amongst the familiar ideas.

The pieces are a mix of essays and adaptations of conference talks. We’ve tried to put them in an order that makes sense. Together we think they cover some of the key ideas in the effective altruism community.

These essays were selected by the Centre for Effective Altruism. Of course, distilling a community’s ideas requires making some difficult judgement calls, and we had to exclude lots of important work. Others in the community would have made a different selection, so at the end we link to other resources that you might find helpful. We are very grateful to all of the authors, for giving us permission to include their work.

The Handbook is also available in Epub or Mobi formats, for people who prefer e-readers.
