In the interest of improving their decision-making, individuals revise their opinions on the basis of samples of opinions obtained from others. However, such a revision process may lead decision-makers to experience greater confidence in their less accurate judgments. We theorize that people...

The purpose of the study is to explore, in the context of the Israeli-Palestinian conflict, the influence of framing a decision task as inclusion or exclusion on Israeli-Jewish respondents' support for the concession of Jewish settlements in the West Bank and Gaza. Respondents received a list of...

Recent advancement in genetics testing for late-onset diseases raises fundamental decision dilemmas. The first study surveyed people’s willingness to undergo predictive testing to find out about their own predisposition for certain incurable, late-onset diseases. The second study investigated...

Seeking advice is a basic practice in making real life decisions. Until recently, however, little attention has been given to it in either empirical studies or theories of decision making. The studies reported here investigate the influence of advice on judgment and the consequences of advice...

The construction of social preferences often requires one to reconcile various social motives, such as concern with unfavorable inequality and maximization of social welfare. We propose a novel theory whereby people's level of agency influences the relative intensities of their social motives,...

Do groups make better judgments and decisions than individuals? We tested the hypothesis that the advantage of groups over individuals in decision-making depends on the group composition. Our study used susceptibility to the framing effect as a measure of decision quality. Individuals were...

People routinely consider the opinions of others prior to making decisions on matters of taste (e.g., a restaurant or movie). Our theoretical framework highlights the role of two sources, social (majority) influence and similarity among advisors, in such decisions. We suggest that individuals'...

The term “social preference” refers to decision makers’ satisfaction with their own outcomes and those attained by comparable others. The present research was inspired by what appears to be a discrepancy in the literature on social preferences – specifically, between a class of studies...
