The COVID-19 pandemic and the World War 2 aerial bombing campaign against the UK between 1939 and 1945 both exposed the civilian population to a sustained threat. Risk, whether from exposure to viral load or the density of the bombing, led to a range of protective measures and behavioural regulations being implemented. The V1 and V2 missiles used in summer and autumn, 1944, functioned as a second wave of bombing, arriving after people believed the danger had passed. Adherence to lockdown and a reluctance to return to work after the lifting of lockdown during the COVID-19 pandemic in the UK were mirrored in the preference for using home-based bomb shelters during the air raids. Heightened sensitivity to risk, or a so-called deep shelter mentality, did not materialise even during the second wave of bomb attacks and some deep bomb shelters were closed because of low occupancy. The most popular protective measures were those that reflected people's preferences, and not necessarily those that provided the greatest safety. As with the COVID-19 pandemic, the public drove government policy as much as they followed it.
