When members of deliberating groups speak with one another, their predeliberation tendencies often become exacerbated as their views become more extreme. The resulting phenomenon -- group polarization -- has been observed in many settings, and it bears on the actions of juries, administrative...

The law forbids discrimination. But the ambiguity of human decision-making often makes it extraordinarily hard for the legal system to know whether anyone has actually discriminated. To understand how algorithms affect discrimination, we must therefore also understand how they affect the problem...

From the streets of Hong Kong to Ferguson, Missouri, civil disobedience has again become newsworthy. What explains the prevalence and extremity of acts of civil disobedience?This paper presents a model in which protest planners choose the nature of the disturbance hoping to influence voters (or...

This paper offers a framework for regulating internalities. Using a simple economic model, we provide four principles for designing and evaluating behaviorally-motivated policy. We then outline rules for determining which contexts reliably reflect true preferences and discuss empirical...

In many settings, human beings are boundedly rational. A distinctive and insufficiently explored legal response to bounded rationality is to attempt to "debias through law," by steering people in more rational directions. In many important domains, existing legal analyses emphasize the...

Many studies find that presentation of balanced information, offering competing positions, can promote polarization and thus increase preexisting social divisions. We offer two explanations for this apparently puzzling phenomenon. The first involves what we call asymmetric Bayesianism: the same...
