夜间伦理：道德选择是否因昼夜时间而异？
Nighttime ethics: Do moral choices differ by time-of-day/night?
摘要
We examine time-of-day (TOD) effects on moral choice by comparing afternoon (DAY: 3pm-5pm) and nighttime (NIGHT: 3am-5am) decisions across three incentivized tasks. While the NIGHT treatment successfully induced sleepiness, we report no evidence that circadian suboptimality shifts decisions towards one’s default ethical tendencies. Rather, the NIGHT treatment increased dishonesty in a victimless Die-Roll task but not when dishonesty harms another participant (modified Coin-Flip task) or in consequential moral dilemmas affecting only others’ outcomes (Payoff-Trolley task). Exploratory response-times evidence is consistent with immoral choices resulting from deliberative processes. Overall, these results indicate that moral choice exhibits task-dependent stability during circadian fatigue.
中文摘要
我们通过在三项有激励的任务中比较下午（白天：下午3点至5点）与夜间（夜晚：凌晨3点至5点）的决策，考察一天中不同时段（TOD）对道德选择的影响。尽管夜晚处理成功诱发了困倦，但我们未发现证据表明昼夜节律次优状态会使决策转向个体默认的道德倾向。相反，夜晚处理增加了无受害者掷骰任务中的不诚实行为，但当不诚实会损害另一名参与者时（修改版抛硬币任务），或在仅影响他人结果的重要道德困境中（收益电车任务），则未出现这种增加。探索性反应时间证据与不道德选择源于审慎过程的观点一致。总体而言，这些结果表明，道德选择在昼夜节律疲劳期间表现出任务依赖的稳定性。
