'Post-Normal Science on Steroids'?

Sonia Sodha has an opinion piece (plugging a TV programme?) on 'post-modern' science (https://www.theguardian.com/commentisfree/2021/mar/20/were-living-in-a-time-of-high-stakes-and-scientific-risks-need-to-be-taken). Sodha's point is that some science has to take place when 'the values around science are in dispute, the stakes are high and decisions urgent'. She describes Covid science as being 'post-normal science on steroids'. Sodha thinks that such circumstances mean that science cannot 'move in a stately fashion with great caution' (did it ever?) and that 'scientific risks have to be taken'. She notes that there has been a politicalisation of science. Politicians choose which bits of science fit their agendas and they can always find a 'scientist', willing to express almost any position. None of this is really new. Science has to be paid for (by grants, charities or by commerce). You can't, in the modern world, be a successful scientist, without the funding to do your science. No papers, no promotions, no employment! Gentlemen scientists, with private means (like Charles Darwin) were always extreme rarities. Science can be remarkably cut-throat. Scientists are human and all have their foibles. They will tend to push particular views. Sodha is right in maintaining, that just because something comes out of the mouth of an eminent scientist, you shouldn't necessarily believe it. I do think, however, that it is better to have rational reasons for taking decisions (or for politicians to take decisions for us). It worries me, when advising expert bodies appear draw on a limited range of study. Urgent decisions may be needed in emergencies. If there is great uncertainty, monitoring has to be in place to assess whether the decision was the right one. It would also be useful to plan how any errors could be quickly reversed. Otherwise, you are simply oscillating between the demands of pressure groups. 'Post-modern science' appears to be just a fancy term for the science/politics interface. The symbiosis becomes more obvious, when the issue is newsworthy.
