Peter examines how social interactions and language shape judgment and decision-making in organizations.
His primary stream of research investigates the social dynamics of confidence, studying how overconfidence and underconfidence shape group decision-making.
A second stream examines how language shapes judgment and behavior, using Large Language Models to identify which features of language influence decision-making.
A third stream investigates how meaningful social connections form in groups, drawing on large-scale data from naturalistic interactions among strangers.
Across these streams, his work combines experiments, field data, and computational methods to understand how social processes shape individual and collective behavior.
