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.

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. (You can take the pledge here.) 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.

My TED talk

How can we do the most good for the world?

In this talk, I introduce the idea of effective altruism, arguing that we should focus on problems that are large in scale, solvable, and neglected, and that one of our top global priorities should be to safeguard humanity’s vast and extraordinary future.
