While the mission is simple, the details aren’t. People have written entire bookshelves of content on ways to increase your impact, drawing from many different disciplines.
To help you learn the basics, we took some of the movement’s best writing and made this handbook. Think of it as the textbook you’d get in your first college course. It explains the core ideas of EA, so that you can start applying them to your own life.[1]
Note that you can also choose and request a free book about some of the most important ideas for effective altruism. You can see more at effectivealtruism.org.
The Introductory Program is a free seminar-based course that covers the same content as the Handbook. We adapted it from programs run by groups at Oxford, Berkeley, and other top universities. New courses start once a month.

Ask a question
Maybe you don’t want to read a whole book, but you’ve got a more specific question. If so, you can ask it on the Forum!
You can also see this article for other ways to get a question answered.
Read the Handbook
The Handbook consists of “sequences” of posts on a single theme. They’ll make more sense if you read them in order, but feel free to skip around.
You can access all the content on this page (see the table of contents on the left). Or you can read from the beginning:
This sequence examines the moral progress we’ve made as a species, and argues that we can do a lot of good by focusing on groups whose welfare is still neglected.
Once we’ve learned the basics, how can we take action?
This sequence suggests ways to get more deeply involved in effective altruism — with your career, your donations, or your free time.
Notes on the Handbook
Some of the articles in the Handbook were written a while ago, so certain elements might be out of date (e.g. statistics). If you see anything that seems especially off, feel free to let us know.
Some articles are listed as coming from “EA Global” or “EA Handbook” rather than a named author. We use the former to collect transcripts of talks from an EA Global conference, and the latter for content written by someone without a Forum account.

Effective altruism is about helping others as much as you can.
This is really difficult, but we’re making progress. And there are many outstanding ways to help. In fact, you can do much more good than you might realize.
