Welcome!

We study how people make wise decisions: in everyday life, across cultures, and over time. Our work sits at the intersection of Social & Cultural Psychology and Judgment & Decision Making, with computational methods and projects on human-AI interactions and AI value alignment.

We combine survey, behavioral, and computational approaches (modeling, NLP, and large-scale analyses), and we preregister studies, share analysis code, and document everything so others can replicate and extend our work.
