Jacy Reese Anthis

Anthis's research focuses on effective altruism, anti-speciesism, and plant-based and cellular agriculture. He was recognized as one of Vice' s "Humans of the Year" in December 2017, along with Witwicki. His book, The End of Animal Farming (2018), argues that animal farming will end by 2100.

After a year and a half at Animal Charity Evaluators, Anthis briefly worked with Sentience Politics, a project of the Effective Altruism Foundation. Sentience Politics then split into two organizations, one of which was the Sentience Institute, co-founded by Anthis and Kelly Witwicki in June 2017. Anthis and Witwicki married in 2020.

Anthis attended the University of Texas at Austin, graduating with a Bachelor of Science and Art degree in 2015.

Before graduating, Anthis worked on the Animal Charity Evaluators Board of Directors; he joined them as a full-time researcher after graduation. Animal Charity Evaluators (ACE, formerly called Effective Animal Activism) is an organization within the effective altruism movement that evaluates and compares various animal charities based on their cost-effectiveness and transparency, particularly those that are tackling factory farming. While at ACE, Anthis published an article that addressed the issue of wild animal suffering, arguing that humans should act on behalf of wild animals to alleviate their suffering if it can be done safely and effectively. His 2015 Vox article on the topic was criticized by writers who argued that humanity should not intervene or that it should instead focus on helping domestic animals.
