Writings and records are how we understand long-gone civilizations without being able to interact with ancient peoples. A recent opinion paper suggested we could feed chatbots writings from the past to simulate ancient participants for social psychology studies. Similar survey experiments with modern participant data closely matched the outcomes of the real people they were based on. We speak with the opinion paper’s co-author Michael Varnum, an associate professor at Arizona State...

Disparities in health are not indicated by adverse outcomes alone. Adriana Corredor-Waldron, an assistant professor of economics at NC State University, sought to understand why Black infants are more likely to be delivered by C-section than white infants. A working paper she co-authored found that the elevated number of low-risk Black pregnant people who were given C-section surgeries in New Jersey from 2008 to 2017 was likely caused by physician discretion. Corredor-Waldron explains why...
