What is the relationship between risk attitudes and ambient temperature? Evidence from a large population-based cohort study
基于2454名老年人的队列数据，发现短期气温变化与一般风险意愿有微小正相关，但与健康相关风险态度无关，表明风险态度在温度变化下相对稳定。
Rising temperatures affect human behavior and risk-taking in several domains. However, it is not yet well understood just how ambient temperature shapes risk attitudes. Using data from the large population-based KORA-Fit study (Cooperative Health Research in the Region of Augsburg) of older people ( N =2454), we identify a statistically significant, but very small, positive association between short-term ambient temperature changes and individuals’ general willingness to take risks. Health-related risk attitudes, however, show no significant relationship with temperature. These findings support a domain-specific view of risk attitudes, with results remaining consistent for vulnerable individuals with the chronic conditions diabetes, hypertension, and asthma. Overall, our findings suggest that risk attitudes are somewhat stable towards changes in ambient temperature. • Ambient temperature has a small positive relationship with general risk attitudes. • Health-related risk attitudes do not significantly relate to ambient temperatures. • Analogous relationships hold for vulnerable individuals with chronic diseases.
