How should we work out how to do good?

What is EA really about?

It's easy to misunderstand effective altruism. This article from 80,000 Hours lays out some of the most common misconceptions and explains what the movement is really about.

We also address many common questions about EA, as well as objections to it, on this page of our site.

Promising causes

Selecting which problem to work on is crucial to having the biggest impact possible. These articles discuss a variety of problems, and why we might, or might not, want to focus on them.

Animal Welfare

Why you might, and might not, want to work on improving animal welfare.

The Long-Term Future

Effective altruism often emphasizes the long-term impact of different interventions. These articles explain why.

Choosing a Charity

Giving What We Can, a community of impact-focused donors, offers an excellent set of giving recommendations (as well as advice on finding high-impact charities yourself).

You can also try this step-by-step guide to choosing a charity from 80,000 Hours, which provides advice on finding a high-impact career. In the guide, they explain:

  • How to choose a promising cause
  • How to evaluate a charity's funding needs
  • Where to find expert donors whose advice you can follow if you'd prefer not to rely on your own research


Doing Good Better is a short podcast series which introduces effective altruism. It is centred around three questions: Why? How? and What?

In the 80,000 Hours Podcast, Rob Wiblin interviews experts from a range of fields about how best to tackle the world's most pressing problems.


Our YouTube channel features videos from Effective Altruism Global and EAGx conferences around the world.

We've created playlists for talks on a variety of topics; you can also check out a playlist featuring more than 100 talks from female, trans, and non-binary speakers, courtesy of WANBAM.

Other Research

In recent years, the effective altruism community has created a lot of good content. Unfortunately, some of that content can be hard to find. We have therefore put together a series of the best research from recent years, including ideas that aren't as widely accepted than the ideas above.

We designed this section for people who are already familiar with some of the core content, and want to understand the ideas in more depth.

How Much Evidence Is Enough?

Argues that we should pursue interventions which have not been conclusively proved, but that we should go on collecting evidence beyond that point.

The EA Forum

The Effective Altruism Forum is an active platform for discussing topics in effective altruism, from scientific research to community building.
