I'm a fan of their research and think it's important to understand the scope of our moral circle and make sure it's not mistakenly too small.

We are a social science think tank researching long-term social and technological change, particularly moral circle expansion. We make our research results public and free, so anyone can use them to make more impactful decisions with their advocacy, careers, donations, and other resources.

We are founded on the principle of effective altruism, meaning we strive to help others as much as possible using the best evidence available. We envision a society in which the interests of all sentient beings are fully considered, regardless of their sex, race, species, substrate, location, or any other characteristic apart from their sentience. We see this expansion as an important means to prevent suffering now and in the far future.

Our mission is to conduct interdisciplinary research on moral circle expansion and to share that research with individuals and institutions making the world a better place. Two particularly important areas of expansion are farmed animals and artificial sentience.
