My primary research interest is in examining why people resist seemingly reasonable messages. Drawing on theorizing around identity and trust, I ask questions such as: "Why do people reject messages of reconciliation?"; "Why do people refute scientific consensus on issues like climate change and immunization; and "why do groups resist criticisms and recommendations for change?" My goal is to build models that help explain defensiveness in he face of messages, with an eye to developing concrete and do-able tools for minimizing this defensiveness.
