Science knowledge and trust in medicine affect individuals’ behavior in pandemic crises
In pandemic crises such as the COVID-19 pandemic, individuals’ behavior has a strong impact on epidemiological processes during critical stages of the outbreak. Engaging in reasonable behavior, such as social distancing, is critical to avoid further spreading an infectious disease or to slow down its spread. However, some individuals also or instead engage in unreasonable behavior, such as panic buying. We investigate why different behavior occurs and how different types of knowledge and trust in medicine can encourage individuals to engage in reasonable behavior and prevent them from engaging in unreasonable behavior. Based on a sample of N = 1,182 adult Americans stratified by age and gender, we conclude that science knowledge has a prophylactic effect: We show that science knowledge helps individuals convert information into knowledge about the coronavirus. This knowledge then helps individuals avoid unreasonable behavior. Individuals lacking coronavirus knowledge and science knowledge still act reasonably when they have a general trust in medicine. Both trust in medicine and knowledge are crucial factors for individuals to act reasonably and avoid unreasonable behavior. Individuals with low knowledge or trust tend to engage in unreasonable behavior. Facilitating science knowledge and reasonable trust in medicine through education and targeted public health messaging are likely to be of fundamental importance for bringing crises such as the 2020 COVID-19 pandemic under control.
