Many of my papers, and my UNICEF lectures on social norms, can be found at https://upenn.academia.edu/CristinaBicchieriMy intellectual affinities lie at the border between philosophy, psychology and behavioral decision making. My research focus is on judgment and decision making, especially pro-social decisions, and how social expectations affect behavior. Social norms are a big part of this work, and many of my experiments show the effect of norms on behavior. I am also interested in the evolution of social norms, how they can emerge and decay. A third, earlier research focus has been the epistemic foundations of game theory and how changes in information affect rational choices and solutions.• In my recent work, I have designed behavioral experiments aimed at testing hypotheses based on the theory of social norms that I developed in my book, The Grammar of Society: the Nature and Dynamics of Social Norms (Cambridge University Press, 2006). The experimental results show that most subjects have a conditional preference for following pro-social norms. Manipulating their expectations causes major behavioral changes. Policymakers who want to induce pro-social behavior have to work on changing people’s social expectations. I have a new book, Norms in the Wild: How to Diagnose, Measure and Change Social Norms, published by Oxford University Press (2017), that summarizes my experience consulting with UNICEF and other NGOs on social norms. Here I stress measurement and change, and what sort of policies may be most conducive to positive social change.
