Partisan Differences in Risk‐Taking in a Simulated Pandemic
Responses to COVID‐19 in the United States were split along partisan political lines throughout the pandemic. People on the political left tended to take the medical threat more seriously and were more likely to adopt preventive health behaviors than those on the political right, resulting in clear differences in state‐level policies and health consequences. Here, we examine the origins of these differences, investigating whether they are based o…
Cheating and the effect of promises in Indian and German children
Cheating is harmful to others and society at large. Promises have been shown to increase honesty in children, but their effectiveness has not been compared between different cultural contexts. In a study (2019) with 7- to 12-year-olds (N = 406, 48% female, middle-class), voluntary promises reduced cheating in Indian, but not in German children. Children in both contexts cheated, but cheating rates were lower in Germany than in India. In both cont…
Effectiveness of Ex-Ante Honesty Oaths in Reducing Dishonesty Depends on Content
Dishonest behaviors such as tax evasion impose significant societal costs. Ex-ante honesty oaths—commitments to honesty before action—have been proposed as interventions to counteract dishonest behavior, but the heterogeneity in findings across operationalizations calls their effectiveness into question. We tested 21 honesty oaths (including a baseline oath)—proposed, evaluated, and selected by 44 expert researchers—and a no-oath condition in a m…

Heterogeneity of rules in Bayesian reasoning
How do people infer the Bayesian posterior probability from stated base rate, hit rate, and false alarm rate? This question is not only of theoretical relevance but also of practical relevance in medical and legal settings. We test two competing theoretical views: single-process theories versus toolbox theories. Single-process theories assume that a single process explains people's inferences and have indeed been observed to fit people's inferenc…
Rivals without a cause? Relative performance feedback creates destructive competition despite aligned incentives
Whether people compete or cooperate with each other has consequences for their own performance and that of organizations. To explain why people compete or cooperate, previous research has focused on two main factors: situational outcome structures and personality types. Here, we propose that—above and beyond these two factors—situational cues, such as the format in which people receive feedback, strongly affect whether they act competitively, coo…
Keeping them honest
People frequently engage in dishonest behavior at a cost to others, and it is therefore beneficial to study interventions promoting honest behavior. We implemented a novel intervention that gave participants a choice to promise to be truthful or not to promise. To measure cheating behavior, we developed a novel variant of the mind game—the dice‐box game—as well as a child‐friendly sender–receiver game. Across three studies with adolescents aged 1…
Competitive escalation and interventions
Competitive escalation occurs frequently in managerial environments, when decisions create sunk costs and decision makers compete under time pressure. In a series of experiments using a minimal dollar auction paradigm, we test interventions to prevent competitive escalation. Without any intervention, most people, including experienced managers, escalate and lose money by bidding more than the price is worth (e.g., more than 10 € for 10 €). We tes…
