Navigating Uncertainty: Understanding Its Impact on Decision Making

In this episode of PsyberSpace, host Leslie Poston digs into the complexities of uncertainty and its effects on decision-making. Leslie explores the psychological and physiological responses to uncertainty, including the role of the amygdala and the concept of Intolerance of Uncertainty (IU). The discussion encompasses cognitive biases like the availability heuristic and ambiguity aversion, and the differential impact of uncertainty across various demographics, including cultural, genetic, and socioeconomic factors. Strategies for improving decision-making under uncertainty are presented, such as leveraging system one and system two thinking, scenario planning, mental simulation, and decision hygiene. The episode concludes with practical advice on building tolerance for uncertainty and making more informed decisions amidst life's lack of predictability.
