Rethink Priorities is a research and implementation group that identifies pressing opportunities and solutions to make the world better. Their work covers important and neglected cause areas, including animal welfare, artificial intelligence, climate change, existential security, global health and development, worldview investigations, as well as surveys and data analyses to understand movements focused on these issues. They work in partnership with a variety of organizations, including foundations and impact-focused nonprofits.

You can explore a lot of their writing (and related discussions about Rethink Priorities) on the EA Forum.

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, in the past year Rethink Priorities:

• Launched a new Worldview Investigations team (which recently completed its sequence on “Causes and Uncertainty: Rethinking Value in Expectation”).
• 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, and launched the Institute for AI Policy & Strategy (IAPS)..
• Produced reports for Open Philanthropy and GiveWell answering questions about global health and development issues and interventions.
