内容提要:

Time pressure has been shown to affect judgment and decision-making quality in the literature. The behavioral economics literature studying this problem however mostly relies on laboratory experiments, which are lacking in scale and real-world relevance. Using the online chess server lichess’s open database, we analyze millions of rated chess games with different formats of time control with each move time-stamped. Using chess engine to evaluate each move’s quality, we find that the probability of blundering increases as the available time decreases, even when players spend more time on each move. Players with higher Elo rating and titled masters, while generally make fewer mistakes, are not immune to the effect of time pressure. Further, using an audio-visual alarm on the platform that goes off when the time is running low as the threshold for regression discontinuity design, we establish causal relationship between time pressure and decision quality.

文献显示,时间压力会影响判断和决策质量。然而,研究这一问题的行为经济学文献大多依赖于实验室实验,这些实验缺乏规模和现实世界的相关性。利用在线国际象棋服务器lichess的开放数据库,我们分析了数以百万计的有不同格式的时间控制的国际象棋游戏,每一步都有时间标记。使用国际象棋引擎来评估每一步棋的质量,我们发现随着可用时间的减少,失误的概率也在增加,即使棋手在每一步棋上花费更多时间。拥有较高Elo等级的棋手和有头衔的大师,虽然一般来说犯错较少,但也不能避免时间压力的影响。此外,使用平台上的视听警报器,当时间快到时就会响起,作为回归不连续设计的门槛,我们建立了时间压力和决策质量之间的因果关系。
