Rethink Priorities

Rethink Priorities

Rethink Priorities’ mission is to generate the most significant possible impact for others in the present and the long-term future. Using evidence and reason, it identifies where resources would be most effective and helps direct them there. It does this by conducting critical research to inform policymakers and philanthropists, and by guiding the development of new organisations to address key problems.


What problem is Rethink Priorities working on?

Rethink Priorities' work covers important and neglected cause areas, including animal welfare, artificial intelligence, climate change, global health and development, and other work to safeguard a flourishing long-term future. It also aims to understand and support effective altruism — the community of people focused on these issues.

What does Rethink Priorities do?

Rethink Priorities works as all of the following:

  • A consultancy doing commissioned work in response to demands from effective altruism organisations.
  • A research institute driven by research agendas it sets according to its own priorities.
  • A think tank aiming to inform public policy to improve the world.
  • An accelerator, incubator, and base for new priority projects.

As part of that work, Rethink Priorities:

  • Studied how to measure and compare the wellbeing of humans and of different other animal species, including its reports on moral weights across species.
  • Helped animal advocacy organisations, policymakers, and funders identify the most cost-effective strategies.
  • Studied how to govern artificial intelligence and other potential risks for future generations.
