Let me throw yet another factor into the mix. Gove's daughter has a test for the virus and when this was questioned we were told it was on the advice of the Chief Scientific Officer. Now, it may well be a good idea to test her in order to get Gove back to work, but that is a political decision, not a scientific one. The scientific decision would be to test the people most likely to infect or be infected by others, which are front-line staff, not daughters of ministers. So in this case at least, it appears the CSO is acting on political factors, not scientific ones. Which immediately raises the question whether this is a one-off, or are political considerations influencing the CSO's advice so that it is no longer truly scientific but some mix of political and scientific. That matters if the government is going to be claiming it is following the scientific advice.
