A successful response to the Covid-19 pandemic is dependent on changing human behaviour to limit proximal interactions with others. Accordingly, governments have introduced severe constraints upon freedoms to move and to mix. This has been accompanied by doubts as to whether the public would abide by these constraints. Such doubts are underpinned by a psychological model of individuals as fragile rationalists who have limited cognitive capacities, who panic under pressure and turn a crisis into a tragedy. Drawing on evidence from the UK, we show that this did not occur. Rather, the pandemic has illustrated the remarkable collective resilience of individuals when brought together as a community by the common experience of crisis. This is a crucial lesson for the future, because it underpins the importance of developing leadership and policies that enhance rather than weaken such emergent social identity.
