The pandemic is a good time to reflect on expertise (if you have the luxury).
During this particular emergency, governments appear to pay heed to experts. Or at least they do now that the extent of the crisis is clear. The public and the media show them respect and even reverence. This is especially true of physicians and public health scientists, especially epidemiologists and virologists. To a lesser extent, social scientists specialising in behaviour and networks weigh in on how to organise life under partial or complete lockdown and how to make this lockdown effective. Economists are voicing ominous warnings on the magnitude of changes to come.

One tempting conclusion is that after decades of being dismissed or scrutinised for their various weaknesses, experts are back with a vengeance. Indeed, it is striking how much more trust politicians and the public are willing to place in epidemiology than, say, in climate science. It is possible that after COVID-19 is overcome, this halo effect will last and many experts will enjoy greater trust, not just the ones whose advice was particularly relevant during the pandemic.
But this prediction may be wishful thinking. The UK government’s abrupt U-turn from mitigation to suppression, while officially justified by scientific advice, is more likely a result of internal rebellion and external criticisms. The critics of mitigation have appealed to a medley of scientific, ethical, political considerations against the pursuit of ‘herd immunity’. Some expressed astonishment at the fact that the UK experts arrived at advice so different from most other countries which overwhelmingly backed suppression. The radical uncertainty about how the epidemic will develop, the disagreements about how to 'flatten the curve' and contain further damage, as well as the now familiar bouts of fakes, misinformation and politicisation of expertise, all undermine the optimistic 'return of the experts' narrative.
Even if the position of the experts after the pandemic will be stronger, this is not a reason to forget how complex and hard-won epistemic authority is. Public health scientists that are now considering strategies of containing the pandemic rely on models with inevitably speculative assumptions. Furthermore, in order to make inferences from these models, they have to make judgments about the appropriate levels of harm to the public, the acceptable numbers of dead, the tolerable restrictions on freedom, the likely behaviour of masses under lockdown, and so on. These judgments are uncertain and controversial, and disagreements between different experts are often intractable. So even if experts are back, their return should not herald their rule.
Professor Elizabeth Anderson of the University of Michigan is a moral philosopher known for her work on expertise and the politics of knowledge. Her writings are a must for anyone who cares about how to define expertise, whether expertise can and should be challenged by laypeople, and what is the proper place of experts in a democracy. Her ideas are as relevant as ever and we recommend two papers in particular. These are classic Anderson papers many of us know and love: they start with a theoretical claim and then illustrate it with historical and contemporary examples of expertise in action.

In this paper, Anderson observes that responsible public policy in a technological society must rely on complex scientific reasoning, which ordinary citizens cannot directly assess. But this inability should not call into question the democratic legitimacy of technologically driven policy. Citizens need not be able to judge whether experts are making justified claims, but rather they need to be able to make, what she calls, reliable second-order assessments of the consensus of trustworthy scientific experts. Her case study is anthropogenic global warming and she argues that judging the trustworthiness of climate experts is straightforward 'for anyone of ordinary education with access to the Web'.
Anderson, E. (2006). The Epistemology of Democracy. Episteme, 3(1-2), 8-22. doi:10.3366/epi.2006.3.1-2.8
This is a paper on how institutions make knowledge, both theoretically and in practice. Theoretically, Anderson reconstructs democracy as an epistemic engine through deliberation and votes, arguing that democracy’s success in this task is due to the experimental nature of its institutions, just as John Dewey taught. Her case study is based on Bina Agarwal's account of community forestry in India and Nepal. Its initial exclusion of women resulted in failure to solve the problem of firewood and fodder shortages.
We recommend reading these papers alongside Anderson’s answers to our questions below. We asked her to answer questions about these topics and she sent us her answers before the pandemic struck. Her reflections are on expertise and democracy in general, not on how it has played out in the last weeks:
Q Considering your research and/or work in practice, what makes a good expert?
- EA: Expertise in any field must join technical knowledge in the field with certain virtues: (i) honesty in communicating findings in the field, including uncertainties about these findings and the most likely alternative possibilities; (ii) conscientiousness in communicating the "whole" truth, in the sense of not omitting findings that are normatively relevant to policymaking, although they may be inconvenient to one or more political views; (iii) avoidance of dogmatism – i.e., a willingness to revise conclusions in light of new evidence; (iv) taking the public seriously: listening to their concerns, which may include distrust of experts, and taking action to earn their trust, rather than dismissing them out of hand or treating them as stupid, even when their concerns are based on misinformation.
Q. What are the pressures experts face in your field?
- EA: As a moral and political philosopher, I am reluctant to claim that there are specifically moral experts, in the sense of people who convey technical conclusions to the public by way of testimony – that is, where we are asking the public to take our word for it in virtue of our being experts, because the considerations for these conclusions are too technical for the public to assess. Philosophers don’t convey findings to the public by way of testimony. We offer ideas, arguments, and perspectives to the public, which they can evaluate for themselves.
Q. Have you observed any significant changes occurring in recent times in the way experts operate?
- EA: We now live in a climate of distrust in expertise, of disinformation spread by social media, irresponsible politicised news, and authoritarian regimes, and of propaganda and toxic discourse that has displaced evidence-based, constructive, democratic policymaking with ideas designed to spread distrust and division among citizens. Some of the distrust in scientific expertise arises from experts themselves, who have failed to take responsibility for bad predictions. Some experts have also been corrupted by moneyed interests. Experts need to repair their broken relations with the public. But it’s not all on them. Conflict entrepreneurs – including populist politicians and media – deliberately spread lies and unfounded doubts about experts, to create a climate in which they can operate with impunity while in power, without taking responsibility for the consequences. Spreading doubt about climate change allows fossil fuel interests to wreck the conditions for a sustainable planet. Spreading doubt about economics may allow plutocrats to drive the UK over a no-deal Brexit cliff. Spreading doubt about the safety of vaccines spreads preventable disease while enriching quack doctors.
Q. Do you envision any changes in the role of experts in the future?
- EA: Experts can no longer rely on their technical knowledge alone, in order to be able to play a constructive role in policymaking. They need to find constructive ways to relate to the public, to engage the public with their findings in ways that both earn their trust and empower the public to distinguish between real experts and those who disseminate lies, propaganda, and toxic discourse. This will require a reinvigoration of democratic practices in conjunction with science. In the U.S., an exemplary case of what I have in mind is the citizen science undertaken in Flint, Michigan, which exposed the presence of lead in the water and consequent lead poisoning of children. In this case, experts – doctors and environmental scientists – empowered citizens to collect data from their own water lines, and reason together about the meanings of their findings and what to do about them. This is democracy in action, empowered by experts in ways that reinforce trust in expertise and democracy alike.
Reading these now, it is hard not to draw connections to the story of expertise during the pandemic. Anderson’s conception of a responsible expert – as transparent about value judgments, respectful of concerns of the public, and properly undogmatic – is a compelling standard against which to evaluate the experts driving the response to the epidemic. But this standard is also tricky to articulate and to apply in the present context. What it would mean for institutions of public health to produce knowledge that is properly representative and practical? Is there a place for citizen science of infectious diseases or does the urgency and danger of a virus like COVID-19 call for a less distributed, more centralised, and frankly a more authoritarian model than Dewey’s? A proper defence of participatory science needs to show that it is not a luxury that can be put aside during crisis, but rather a necessity. This is far from obvious. What could a citizen science about COVID-19 be? And how can such science command trust in an age of misinformation?
In an email on March 26th Anderson added that citizen science on COVID-19 is already happening:
- Citizen science resources related to the COVID19 pandemic
- Citizen Scientists Are Helping Researchers Design New Drugs to Combat COVID-19
We also wonder how Anderson's view that the trustworthiness of experts is a second-order question (recall she argues that the public need not know the science to trust the experts), help us to understand the trustworthiness of epidemiologists in the time of COVID-19. How do they marshal as much trust as they do, at least once they do, and what accounts for the contrast with, say, climate scientists? Is epidemiologists' knowledge or character somehow superior to that of so many other distrusted experts? Or is there something about the clear and present urgency of a pandemic and the vividly obvious threats to one’s own life that makes an expert on it trustworthy? (We mean to say trustworthy, rather than trusted, because, as the precautionary principle recommends, when the risk of tragedy is high, it is appropriate to act on less evidence than otherwise.) If so, the proper response to climate scepticism is not better science or better experts as such, but a better representation of urgency and crisis.
There is much more to say and in the coming weeks the Expertise Under Pressure team will be publishing our own and invited commentary on the role of experts during this pandemic. But the writings of classics such as Elizabeth Anderson are an obligatory passage point.
