Why is the government relying on nudge theory to fight coronavirus? | Tony Yates

It would be good to know the evidence for the UK strategy - which is starkly different to that of other countries

With an estimated 5,000 to 10,000 coronavirus cases now present in the UK, the government has eschewed social distancing measures such as closing schools and banning large sporting events. Instead, it has opted for behavioural "nudges": wash your hands, don't touch your face, don't shake hands with others, stay at home if you feel ill, and self-isolate if you have a continuous cough.

This approach differs starkly from the quarantine measures taken in China, South Korea, Italy and Iran. But it also marks the UK out as different from countries such as Ireland, Norway and Denmark, which have implemented school closures despite seeing only a relatively small number of coronavirus cases. Patrick Vallance, the government's chief scientific adviser, has explained that part of the reason for not embracing bans is to encourage "herd immunity". Allow enough of those who can survive coronavirus disease to get infected, and the virus won't have new people to infect, meaning new cases will dry up. Other European countries seem to have judged this too bold an approach. Immunity will probably be temporary, so later outbreaks are to be expected, and dealt with by heightened contact tracing when they occur.
