Life in the pandemic I: The return of the experts….


It wasn’t that long ago that some were lamenting the death of reason and the revolt against experts. TV studios were filled with serious looking people trying to work out how it was possible for on the one hand Donald Trump to be elected in the United States and on the other the UK voting to leave the EU. Clearly, they intoned, the populus of both countries had taken leave of their senses. Expertise was under attack and ignorance was being encouraged, commended and rewarded. There was perhaps some truth in this.

Both experts and expertise came in for a bit of a kicking, particularly in the US. Experts formed a convenient target of course. This was partly because the terms were rarely clearly defined. Blame was attributed to an amorphous group, without examining too carefully if it was experts who were the problem, or the political decision makers. Many of the latter seemed unwilling to engage properly with a whole range of issues, inform themselves using appropriate expert input, and take and be accountable for the decisions that people elected them to take. In the UK we got into the Brexit mess (remember that?) partly because of this sort of political cowardice. A host of complex issues, requiring a range of expertise to unpack them, was boiled down to a binary choice and forced on a population that consistently claimed that it was generally ill-informed, and in some cases actively deceived. A proportion of the population appeared to be delighted with this general approach. On both sides of the Atlantic the notion gained traction that the experts had done too many of us no good at all. They were therefore of little value and could happily be dispensed with. How things have changed.

As I have pointed out before, there are many situations in life where we are happy and indeed obliged to depend on the expertise of others. I do not have the first notion about how to fly an aeroplane, but (until recently) I needed to use them from time to time. What to do? Well, fortunately for me there are experts in flying aeroplanes; they are called airline pilots. There used to be quite a lot of them flying aeroplanes with skill, and able to fly me safely from point A to point B. I was really glad to avail myself of their expertise. And not just theirs. It turns out that while they were using their expertise for my benefit, they in turn were depending on the expertise of lots of other people, like air traffic controllers, aircraft maintenance engineers, and a whole host of others. Together, all this expertise could safely transport me thousands of miles at a time. I was happy to trust them to do so. Clearly some experts have their uses.

Now we find ourselves in a situation where expertise turns out to be a matter of life and death, potentially for thousands. The centrality accorded to expertise in these pandemic days has been clear for all to see. At least in the UK great stress has been put on policy being informed by scientific and medical experts. Day after day the Prime Minister or other senior ministers have appeared flanked by experts to whom they constantly defer. Of course there could be a deep cynicism at work. It could be, and no doubt some will argue it is, simply the politicians using the claimed expertise of others as cover for them taking very unpopular decisions. But I don’t think that’s what’s going on. I think that in life-critical situations, it turns out we have no problem taking experts and expertise seriously. This is our attitude in aeroplanes, and it appears to be our attitude in the pandemic. At least for the most part.

Perhaps the consistent undermining and downplaying of expertise is recent times explains why governments are finding that advice, sound advice based on science, is frequently being ignored. Just this week, it has been stressed just how important it is that in the current pandemic we socially isolate ourselves and not meet with others unless it is necessary. Other experts have told us that there is no necessity to panic buy and hoard foodstuffs and other thing (like toilet rolls - for reasons no-one seems able to fathom). And yet the flagrant disregarding of “advice” now means the state taking powers to enforce what the science says should be done. All over Europe, and now in the UK, there will be police (and in some places military) enforcement of the advice. Expertise is back, and with teeth.

It is still the case that not all expertise is the same and we need to understand some important distinctions.  For the appropriate expert, flying an aeroplane is a well constrained and defined task. While it is not true to say that there are no unknowables, there are relatively few. Do things in a certain way, in a certain order, and a safe flight will result – usually. “Usually” in this context means almost always; in 2018 there were only 0.36 fatal accidents per million flights. However, the expertise we’re depending on in the pandemic is different, although it is no less expertise. Here there are very many unknowns. We are dealing with a new virus and while information about it is accumulating, no one has anything like the full picture. So the scientific advice that decision-makers are relying upon is a best effort, based on the information to hand. And sometimes, experts looking at the same evidence may well interpret it in different ways. There are different models of how the virus is spreading, leading to different projections of how the pandemic may develop, and potentially different recommendations about the actions that should be taken to improve the situation. Then factor in that any advice issued has to be heard, understood and acted upon by millions of citizens. You can see how the unknowns in this situation rapidly multiply. But the experts and (in this case) their scientific methods are all we’ve got, and a lot better than the alternative - either doing nothing, or doing anything.

The experts have returned. Time to exercise a bit of faith; although let’s be clear – that’s what we’re doing. Putting our faith in experts and their expertise (again). And on a planetary scale.
