新研究：决策反馈可能增加人们冒险倾向

Core Insights - A new study involving French researchers indicates that feedback received after decision-making does not improve the quality of subsequent decisions but may increase risk-taking behavior [1][2]. Group 1: Study Findings - The study involved over 500 participants who made choices between certain options and risky options, assessing decision quality based on their ability to choose higher-reward options [1]. - Feedback, whether partial or complete, led to a systematic increase in risk-taking behavior by 35% to 45% compared to no feedback, without a significant improvement in decision quality [2]. - The increase in risk-taking under partial feedback may be driven by curiosity, while under complete feedback, it may stem from a fear of regret from making the wrong choice [2]. Group 2: Implications - The findings suggest a need to reassess the role of feedback in decision-making, particularly in fields such as finance, health, and public policy, as it may enhance risk preference rather than promote rational learning [2].
