This research investigates the relationship between cumulative lifetime stressor exposure and ambiguity aversion in economic decision-making. Two studies (Study 1: n = 58; Study 2: n = 188) utilized the Stress and Adversity Inventory for Adults (STRAIN) to measure lifetime stressor exposure and an economic decision-making paradigm to quantify risk and ambiguity preferences. Results consistently demonstrated that greater lifetime stressor exposure, particularly in early life, was significantly associated with higher ambiguity aversion but not with risk preferences. These findings suggest a potential causal link between cumulative stress exposure, especially during developmentally sensitive periods, and the development of ambiguity aversion.
