Precis: The Most Good You Can Do†

Effective altruism is based on a very simple idea: we should do the most good we can. Obeying the usual rules about not stealing, cheating, hurting, and killing is not enough, or at least not enough for those of us who have the great good fortune to live in material comfort, who can feed, house, and clothe ourselves and our families and still have money or time to spare. Living a minimally acceptable ethical life involves using a substantial part of our spare resources to make the world a better place. Living a fully ethical life involves doing the most good we can. Effective altruism is notable from several perspectives. First, and most important, it is making a difference to the world. Philanthropy is a very large industry. In the United States alone there are almost one million charities, receiving a total of approximately $250 billion a year, with an additional $100 billion going to religious congregations. A small number of these charities are outright frauds, but a much bigger problem is that very few of them are sufficiently transparent to allow donors to judge whether they are really doing good. Most of that $250 billion is given on the basis of emotional responses to images of the people, animals, or forests that the charity is helping. Effective altruism seeks to change that by providing incentives for charities to demonstrate their effectiveness. Already the movement is directing tens of millions of dollars to charities that are effectively reducing the suffering and death caused by extreme poverty. Second, effective altruism is a way of giving meaning to our own lives and finding fulfillment in what we do. Many effective altruists say that in doing good, they feel good. Effective altruists directly benefit others, but indirectly they often benefit themselves. Third, effective altruism sheds new light on an old philosophical and psychological question: Are we fundamentally driven by our innate needs and emotional responses, with our rational capacities doing little more than laying a justificatory veneer over actions that were already determined before we even started reasoning about what to do? Or can reason play a crucial role in determining how we live? What is it that drives some of us to look beyond our own interests and the interests of those we love to the interests of strangers, future generations, and animals? Finally, the emergence of effective altruism and the evident enthusiasm and intelligence with which many millennials at the outset of their careers are embracing it offer grounds for optimism about our future.
