Modeling Human Risk Learning

We modeled how people learn about risks—think of drug side effects, vaccinations efficacy, asset returns, pension savings, and many more.

Understanding the risks of our choices matters for well-informed decision making. To gain empirical insights into the cognitive processes (thought and memory processes) of how and when people grasp small and large risks, we used a data-based and cognitive machine-learning approach. In two data-sets, we determined what kind and amount of experience or numerical information was necessary such that particularly small risks would be understood well. In an economic setting, we found that there are two distinct types of learning about risks, and they differ in how they deal with incoming experience about risks. This cognitive machine-learning analyses explains the paradox that some people failed to learn about the risk with experience.
