What is effective altruism?Edit

Effective Altruism is a movement of people who aim to make the world a better place in the ways which evidence suggests are among the most effective. A classic example of doing so is donating large quantities of money to highly cost-effective direct charities. Prominent philosopher Peter Singer has advocated ideas shared by many effective altruists since his 1972 paper 'Famine, Affluence and Morality'; recently he has adopted the effective altruist label, and in early 2015 published a book about it. See Singer's TED Talk on Effective Altruism for an introduction to the concept. For fuller definitions, see effective altruism in brief. For more, see introductions to effective altruism.

Direct charities are those which conduct programs which help people or animals in relatively direct ways, as opposed to meta charities, which typically move resources to direct charities.
