Covid, lockdown and the retreat of scientific debate

Science is about rational disagreement, the questioning and testing of orthodoxy and the constant search for truth. With something like lockdown – an untested policy that affects millions – rigorous debate and the basics of verification/falsification are more important than ever. Academics backing lockdown (or any major theory) ought to welcome challenges, knowing – as scientists do – that robust challenge is the way to identify error, improve policy and save lives.
