Triple Contagion: Toward Cognitive Epidemiology
- Speaker: Joshua Epstein, New York University
- Date and Time: Tuesday, November 2, 2021 - 1:00pm to 2:00pm
- Abstract: In this colloquium, differential equation and agent-based models in which contagious disease transmission is affected by contagious fear of the disease and contagious fear of the control, in this case vaccine will be presented. The three contagions—one viral-particulate and two cognitive--are coupled. The two fears evolve and interact in ways that shape distancing behaviour, vaccine uptake, and their relaxation. These behavioural dynamics in turn can amplify or suppress disease transmission, revealing several coupled contagion mechanisms for multiple pandemic waves, including cases where waves increase in amplitude. Methodologically, the coupled contagion approach advances infectious disease modelling by including human behavioural adaptations, grounded in the cognitive neuroscience of fear learning, extinction, and transmission.
