Welcome

We propose and develop a dynamic theory of endogenous preference formation in which people adopt worldviews that shape their judgments about their experiences. The framework highlights the role of mindset flexibility, a trait that determines the relative weights the decision-maker places on her current and anticipated worldviews when evaluating future outcomes. The theory generates rich behavioral dynamics, thereby illuminating a wide range of applications and providing potential explanations for a variety of observed phenomena.

We investigate how individuals think groups should aggregate members’ ordinal preferences – that is, how they interpret “the will of the people.” In an experiment, we elicit revealed attitudes toward ordinal preference aggregation and classify subjects according to the rules they apparently deploy. Majoritarianism is rare. Instead, people employ rules that place greater weight on compromise options. The classification’s fit is excellent, and clustering analysis reveals that it does not omit important rules.

In settings with uncertainty, tension exists between ex ante and ex post notions of fairness. Subjects in an experiment most commonly select the ex ante fair alternative ex ante and switch to the ex post fair alternative ex post. One potential explanation embraces consequentialism and construes reversals as time inconsistent. Another abandons consequentialism in favor of deontological (rule-based) ethics and thereby avoids the implication that revisions imply inconsistency. We test these explanations by examining contingent planning and the demand for commitment.
