A radical reassessment of how we can most effectively help others by a rising star of philosophy and leading social entrepreneur.'A surprising and often counterintuitive look at the best ways to make a difference . . . MacAskill is that rarest of beasts: a do-gooder who uses his head more than his heart.'SUNDAY TIMESMost of us want to make a difference. We donate to charity, buy Fairtrade coffee, or try to cut down on our carbon emissions. Rarely do we know if we're really helping, and despite our best intentions, our actions can have ineffective - and sometimes downright harmful - outcomes. Confronting this problem, William MacAskill developed the concept of effective altruism, a practical, data-driven approach which shows that each of us has the power to do an astonishing amount of good, given the right information. His conclusions are often surprising; by examining the charities we give to, the goods we buy and the careers we pursue, Doing Good Better is a fascinating and original guide which shows how, through simple actions, you can improve thousands of lives - including your own.'A data nerd after my own heart.'BILL GATES'Required reading for anyone interested in making the world better.'STEVEN LEVITT, co-author of Freakonomics'Effective altruism - efforts that actually help people rather than making you feel good or helping you show off - is one of the great new ideas of the 21st century. Doing Good Better is the definitive guide to this exciting new movement.'STEVEN PINKER, author of The Better Angels of Our Nature
