William MacAskill

I'm Will MacAskill, Associate Professor in Philosophy and Research Fellow at the Global Priorities Institute, University of Oxford. My academic research focuses on the fundamentals of effective altruism - the use of evidence and reason to help others by as much as possible with our time and money, with a particular concentration on how to act given moral uncertainty.

I am the author of Doing Good Better - Effective Altruism and a Radical New Way to Make a Difference, and Moral Uncertainty. My latest book is What We Owe The Future.

I am the Director of the Forethought Foundation for Global Priorities Research, a co-founder and the President of the Centre for Effective Altruism (CEA) and I helped to create the effective altruism movement. Through Giving What We Can, CEA encourages people to commit to donate at least 10% of their income to the most effective charities. CEA also runs over 100 effective altruism local groups, hosts regular effective altruism conferences, and does research into high-impact policy and philanthropic opportunities.

I also co-founded 80,000 Hours, a YCombinator-backed non-profit that provides research and advice on how you can best make a difference through your career.
