Studying group decision-making is challenging for multiple reasons. An important logistic difficulty is studying a sufficiently large number of groups, each with multiple participants. Assembling groups online could make this process easier and also provide access to group members more...

Interventions to increase cooperation in social dilemmas depend on understanding decision makers' motivations for cooperation or defection. We examined these in five real-world social dilemmas: situations where private interests are at odds with collective ones. An online survey (N = 929) asked...

In two studies, time preferences for financial gains and losses at delays of up to 50 years were elicited using three different methods: matching, fixed-sequence choice titration, and a dynamic ``staircase'' choice method. Matching was found to create fewer demand characteristics and to produce...

Past research has shown that people consistently believe that others are more easily manipulated by external influences than they themselves are---a phenomenon called the ``third-person effect'' (Davison, 1983). The present research investigates whether support for public policies aimed at...

We propose a constructed-choice model for general decision making. The model departs from utility theory and prospect theory in its treatment of multiple goals and it suggests several different ways in which context can affect choice. It is particularly instructive to apply this model to...

Morally challenging decisions tend to be perceived as difficult by decision makers and often lead to post-decisional worry or regret. To test potential causes of these consequences, we employed realistic, morally challenging scenarios with two conflicting choice options. In addition to...

This paper proposes a revised version of the original Domain-Specific Risk-Taking (DOSPERT) scale developed by Weber, Blais, and Betz (2002) that is shorter and applicable to a {broader range of ages, cultures, and educational levels}. It also provides a French translation of the revised scale....
