Contributor(s): Professor Nick Chater, Professor Liam Delaney, Professor Paul Dolan, Professor Ulrike Hahn, Dr Grace Lordan | The impacts of COVID-19 and how we deal with them hinge on how politicians, firms and the public respond. What lessons can we learn from behavioural science about how we act in a time of crisis characterised by great uncertainty? What lessons can behavioural science learn about how it can be best placed to provide guidance in an uncertain world? Answers to these questions are crucial to not only mitigating the impacts of COVID-19 but also to dealing better with future crises, not only caused by viruses but also by other shocks.

COVID-19 represents an enormous challenge for the social sciences to help governments and non-governmental organisations respond to the economic and societal consequences of the pandemic. Part of LSE's response to this challenge is a series of online public events that will take place over the Summer Term. Why not visit the School of Public Policy COVID-19 Resource Centre. This event in the series has been organised by the Department of Psychological and Behavioural Science. The next event in this series will take place at 4pm on 13 May on Transboundary Crisis Management in Europe in the Wake of COVID-19. The Department of Psychological & Behavioural Science (@LSE_PBS) is a growing community of researchers, intellectuals, and students who investigate the human mind and behaviour in a societal context.
