Effective Altruists are here to help change the world for the better! And we're open to whatever lets us do that most effectively, be it hard evidence or new ways of thinking.

Effective Altruism is a simple concept, but as a philosophical and social movement it has a surprisingly short history. Some of the key components of effective altruism are:

There is a substantial amount of relevant information on the web, including evaluations and recommendations of charities, philosophical discussions and career advice.

Getting Involved

There are many venues for discussing effective altruism, both on the Internet and local groups. If there isn't a group in your area, it's easy to start one. There are many other ways to get involved.

If you're not a native English speaker, check out EA venues in other languages, and feel free to make EA Wiki pages in any language.

Already into EA? A key strategy for doing good effectively is to encourage others to do the same. Read about how to talk about EA, and very brief EA summaries.

New to EA? Have a look at Peter Singer's TED Talk on Effective Altruism, or these introductions to EA.


Staying informed is crucial to the EA philosophy. The library links to an extensive amount of EA information on the web. Charity evaluators such as GiveWell, Giving What We Can and Animal Charity Evaluators have performed in-depth research into many charities and provide detailed write-ups including recommendations.


A key part of effective altruism is donating. Earning to give is a career strategy aimed at raising funds through high-paying work, and donating a significant portion. Some donors are concerned with making donations public, and with tax efficiency.

Sometimes even small actions can have outsized impact.
