Research investigating collective decision-making has focused primarily on the improvement of accuracy in collective decisions and less on the motives that drive individuals to make these decisions. We argue that a strong but neglected motive for making collective decisions is minimizing the material and psychological burden of an individual’s responsibility. Making difficult decisions with others shields individuals from the consequences of negative outcomes by reducing regret, punishment and s...

Does birth order shape people’s propensity to take risks? Evidence is mixed. We used a three-pronged approach to investigate birth-order effects on risk taking. First, we examined the propensity to take risks as measured by a self-report questionnaire administered in the German Socio-Economic Panel, one of the largest and most comprehensive household surveys. Second, we drew on data from the Basel–Berlin Risk Study, one of the most exhaustive attempts to measure risk preference. This study admin...

Despite the ubiquity of uncertainty, scientific attention has focused primarily on probabilistic approaches, which predominantly rely on the assumption that uncertainty can be measured and expressed numerically. At the same time, the increasing amount of research from a range of areas including psychology, economics, and sociology testify that in the real world, people’s understanding of risky and uncertain situations cannot be satisfactorily explained in probabilistic and decision-theoretical t...

Risk preference is one of the most important building blocks of choice theories in the behavioural sciences. In economics, it is often conceptualized as preferences concerning the variance of monetary payoffs, whereas in psychology, risk preference is often thought to capture the propensity to engage in behaviour with the potential for loss or harm. Both concepts are associated with distinct measurement traditions: economics has traditionally relied on behavioural measures, while psychology has ...

An extensive literature exists comparing the predictive power of Cumulative Prospect Theory (CPT) and Expected Utility Theory (EUT) in decisions from description. CPT accommodates the empirically observed deviations from EUT primarily by assuming a nonlinear probability weighting function and loss aversion. An alternative explanation is that decision makers have preferences for higher-order moments, beyond the mean and variance of lotteries — we extensively test the Mean-Variance-Skewness (MVS) ...

Abstract Objective We investigated the effects of information structuring and its potential interaction with pre-existing medical knowledge on recall in a simulated discharge communication. Methods 127 proxy-patients (i.e. students) were randomly assigned to one of four conditions. Video vignettes provided identical information, differing in means of information structuring only: The natural conversation (NC) condition was not explicitly structured whereas the structure (S) condition presented i...
