Research
One premise, three programs
Moral psychology can only be understood in cultural context. Our three research programs approach that premise from different directions, across history and geography, across moral systems, and across methods.
01
Culture Across Time and Place
How and why do psychological processes vary across history and across cultures?
We study how values, norms, emotions, and beliefs vary across societies and shift across historical time.
Minds are shaped by the cultural worlds people inhabit, and those worlds change. Because most psychological research rests on WEIRD (Western, Educated, Industrialized, Rich, and Democratic) samples, we work with populations beyond that narrow slice, mapping where familiar findings generalize and where they break down, and we extend the same questions backward in time, using text corpora and archival records to trace how moral and psychological concepts have evolved across generations.

02
Pluralistic Morality
How do different moral systems bind people together, or divide them into “us” versus “them”?
We treat morality as plural, several distinct concerns rather than one thing, and study the work each does in social life.
People and cultures build moral systems from multiple concerns: care, fairness, loyalty, authority, purity, and more. The same moral psychology that makes large-scale cooperation possible can also sharpen the boundaries between groups, escalating into hostility, radicalization, and violence. Treating morality as plural lets us ask precisely which moral concerns, in which cultural contexts, bind people together, and which divide them into “us” versus “them.”
