Temperature and Decisions: Evidence from 207,000 Court Cases
研究发现，室外温度升高会显著降低美国移民法官对申请人有利的裁决比例，即使法官在空调房内工作，温度仍通过影响情绪和风险偏好发挥作用。
We analyze the impact of outdoor temperature on high-stakes decisions (immigration adjudications) made by professional decision-makers (US immigration judges). In our preferred specification, which includes spatial, temporal, and judge fixed effects, and controls for various potential confounders, a 10°F degree increase in case-day temperature reduces decisions favorable to the applicant by 6.55 percent. This is despite judgements being made indoors, “protected ” by climate control. Results are consistent with established links from temperature to mood and risk appetite and have important implications for evaluating the influence of climate on “cognitive output.”
