Effective Altruism: An Introduction – 80,000 Hours (April 2021) Eight: Prof Hilary Greaves on moral cluelessness, population ethics, & harnessing the brainpower of academia to tackle the most important research questions
02:48:33
Transition Fueled By Practical Questions
- Hilary Greaves shifted from philosophy of physics to moral philosophy because practical, everyday questions motivated her originally.
- Foundational training (decision theory, math) helped her transition and tackle global priorities research.
Probability Via Branch Measures
- Many-worlds interpretation needs a measure over branches to recover probabilities for decision-making.
- Assigning weights to branches plus decision theory gives the probabilities we need in practice.
Expect A Fallow Period When Switching
- If you want to switch research fields, expect a fallow period and loss of immediate publications.
- Keep curiosity and persistence; your broader skills often transfer and will pay off long-term.

The barista gives you your coffee and change, and you walk away from the busy line. But you suddenly realise she gave you $1 less than she should have. Do you brush your way past the people now waiting, or just accept this as a dollar you’re never getting back?
According to philosophy Professor Hilary Greaves - Director of Oxford University's Global Priorities Institute, this simple decision will completely change the long-term future by altering the identities of almost all future generations.
This conversation from 2018 blends philosophy with an exploration of the mission and research agenda of the Global Priorities Institute: to develop the effective altruism movement within academia.
