The World Health Organization amplified false Chinese statements about COVID-19 initially, while it dragging its feet on declaring an international emergency. Pandemic experts here clung to flu epidemic plans too, ignoring observable COVID-19 successes in East Asia and so ruling out any similar possibility of test-and-trace containment in the UK from the off.
Most public health experts then pivoted to being extremely pro-lockdown, but stuck rigidly to this even as the context, and so the costs and benefits of restrictions, changed with the vaccines and omicron.
Epidemiologists proved especially stubborn. Their modelling usually ignored the role of voluntary behavioural change entirely, so erred on the side of assuming catastrophic public health outcomes absent government mandates and restrictions. Hence, Freedom Day was dubbed “criminal” by scientists, while the government’s scientific advisers called for more restrictions last Christmas. Both proved wrong in retrospect.
