Effective Altruism


This site is intended to be an introduction to effective altruism.  It is currently under development, and the full site will be taken live in due course.  If you would like to contribute to this effort please contact us.  


Effective altruism is a growing community based around the idea of aiming to do the most good that one can

It involves:

  1. Being open to all the possible ways to do good and pursuing the path with the biggest positive impact
  2. Using evidence to figure out how to do the most good
  3. Making helping others an important part of your life

What is effective altruism?

  • There are so many problems in the world, from extreme poverty, gender inequality, animal suffering, risk of war, and thousands more.
  • One person cannot solve all of these problems in their lifetime. This means we need to prioritize.
  • Effective altruism is about asking: of all the possible ways to make a difference, which will make the most difference? 

    Of all the possible ways to make a difference, which will make the most difference?

How do we answer this question?

What has effective altruism achieved?

What do effective altruists do?

There are a wide variety of ways to do a huge amount of good in the world.

Many effective altruists do good by making donations. For example, Julia Wise, a social worker, and her husband Jeff Kaufman, an engineer at Google, donate half of their income to the most cost-effective causes.

Here are some examples of other paths:

  • Setting up companies with a social mission. Lincoln Quirk co-founded Wave, which dramatically reduces the costs for US immigrants to send money back to their families.
  • Setting up non-profits. Finding that university wasn’t teaching her the skills she needed, Xio Kikauka left in order to set up Charity Science, which fundraises for the most cost-effective charities.
  • Research. Holden Karnofsky and Elie Hassenfield quit their jobs at an investment management firm, in order found GiveWell and do charity evaluation.
  • Politics. Habiba Islam took up law and is now building skills in strategy consulting with the aim of moving into politics.
  • Advocacy and education. Julia Galef co-founded the Centre for Applied Rationality, in order to improve the people’s decision-making skills.

  1. GiveWell has raised over $10m for Against Malaria Foundation, which buys bed nets at the cost of less than $7 each.  This suggests that the community will have enabled at least one million bed nets to be delivered once the distributions have been arranged by Against Malaria Foundation

  2. GiveWell has raised over $4m for Schistosomiasis Control Initiative, which funds deworming for parasitic worm infections at the cost of less than $1 per treatment.  This suggests that the community has provided the funds for the treatment of over four million children from parasitic worm infections. 

  3. See 80,000 Hours’ plan change analysis for some examples. 

  4. GiveWell has raised over $12m for Give Directly.  Give Directly have been ensuring at least 87% of their intervention expenses end up in the hands of their programme recipients.  This suggests that the community will have provided at least $10m in funding for direct cash transfers to some of the world’s poorest people

  5. GoodVentures and GiveWell work very closely together, share offices

  6. The Global Priorities Project is a project of the Centre For Effective Altruism, which also houses Giving What We Can and 80,000 Hours.  Staff from the Centre of Effective Altruism have had many meetings with UK Government officials in a range of departments including the Prime Minister’s Office, the Government Office for Science, the Cabinet Office, and the Department for International Development on a range of policy issues. 

  7. We’re very willing to help each other out, and always enjoy talking about ways of increasing our impact!
