Okunskap och riskkommunikation: Att knuffa eller ge en karta

Around the world Covid-19 has been battled by trying to get the public to change how they behave: to reduce social interactions and the risks associated with them. In order to change behaviour it is not enough, however, to simply tell people what to do. Successful interventions also need to communicate how to do it. Here I discuss the difference between nudges (influencing behaviour) and boosts (developing decison making compentencies), and I describe the role that the publics' mental models of the pandemic play in determining their actions.
