Effective altruism is about helping others as much as you can.
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.
Since you're interested in this topic, we'd also like to offer you two free books on EA: Will MacAskill's Doing Good Better and Toby Ord's The Precipice. Both books are part of the Handbook, though they are optional — you can start reading now without them.
Take the online course
Would you like to meet others interested in effective altruism, and discuss these ideas with an experienced facilitator?
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.
Read the book
Would you rather go at your own pace and get started right away? Read on!
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:
If you want to start with just one article, make it our brief intro essay. (The Handbook starts with a more detailed introduction.)
Note: The Handbook is a work in progress! We're still working to add more content, more summaries, and other useful features. We'd welcome your feedback.
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!

Table of Contents
Why is it so important to focus on "effective" altruism?
This sequence shows that despite our limited resources, we can accomplish incredible things when we think carefully before taking action.
How can we tell which actions do the most good?
This sequence covers ways to measure your impact and find especially promising issues to work on.
Who should we care about helping?
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.
How should we think about the long-term impact of our actions?
This sequence makes the case that some of the most important work we can do involves trying to improve the long-term future of civilization.
What can we do to prevent the worst possible outcome for humanity?
This sequence explores the possible end of human civilization, and how we can work to safeguard the future of our species.
How should we prepare for technology that could reshape our existence?
This sequence looks at two ways in which future technology could pose an existential threat to humanity, and how we can address those threats.
What are some potential problems with effective altruism, and how should we respond?
This sequence covers prominent critiques of EA, as well as responses and counterarguments from people within the movement.
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.
