The constructionist hypothesis and expertise during the pandemic

Now that COVID-19 cases are rising again in the country, the trash talk against journalists has been rising in tandem. The Indian government was unprepared and hapless last year, and it is this year as well, if only in different ways. In this environment, journalists have come under criticism along two equally unreasonable lines. First, many people, typically supporters of the establishment, either don’t or can’t see the difference between good journalism and contrarianism, and don’t or can’t acknowledge the need for expertise in the practise of journalism.

Second, the recognition of expertise itself has been sorely lacking across the board. Just like last year, when lots of scientists dropped what they were doing and started churning out disease transmission models each one more ridiculous than the last, this time — in response to a more complex ‘playing field’ involving new and more variants, intricate immunity-related mechanisms and labyrinthine clinical trial protocols — too many people have been shouting their mouths off, and getting most of it wrong. All of these misfires have reminded us of two things: again and again that expertise matters, and that unless you’re an expert on something, you’re unlikely to know how deep it runs. The latter isn’t trivial.

There’s what you know you don’t know, and what you don’t know you don’t know. The former is the birthplace of learning. It’s the perfect place from which to ask questions and fill gaps in your knowledge. The latter is the verge of presumptuousness — a very good place from which to make a fool of yourself. Of course, this depends on your attitude: you can always be mindful of the Great Unknown, such as it is, and keep quiet.

As these tropes have played out in the last few months, I have been reminded of an article written by the physicist Philip Warren Anderson, called ‘More is Different’, and published in 1972. His idea here is simple: that the statement “if everything obeys the same fundamental laws, then the only scientists who are studying anything really fundamental are those who are working on those laws” is false. He goes on to explain:

“The main fallacy in this kind of thinking is that the reductionist hypothesis does not by any means imply a ‘constructionist’ one: The ability to reduce everything to simple fundamental laws does not imply the ability to start from those laws and reconstruct the universe. … The constructionist hypothesis breaks down when confronted with the twin difficulties of scale and complexity. The behaviour of large and complex aggregates of elementary particles, it turns out, is not to be understood in terms of a simple extrapolation of the properties of a few particles. Instead, at each level of complexity entirely new properties appear, and the understanding of the new behaviours requires research which I think is as fundamental in its nature as any other.”

The seemingly endless intricacies that beset the interaction of a virus, a human body and a vaccine are proof enough that the “twin difficulties of scale and complexity” are present in epidemiology, immunology and biochemistry as well – and testament to the foolishness of any claims that the laws of conservation, thermodynamics or motion can help us say, for example, whether a particular variant infects people ‘better’ because it escapes the immune system better or because the immune system’s protection is fading.

But closer to my point: not even all epidemiologists, immunologists and/or biochemists can meaningfully comment on every form or type of these interactions at all times. I’m not 100% certain, but at least from what I’ve learnt reporting topics in physics (and conceding happily that covering biology seems more complex), scale and complexity work not just across but within fields as well. A cardiologist may be able to comment meaningfully on COVID-19’s effects on the heart in some patients, or a neurologist on the brain, but they may not know how the infection got there even if all these organs are part of the same body. A structural biologist may have deciphered why different mutations change the virus’s spike protein the way they do, but she can’t be expected to comment meaningfully on how epidemiological models will have to be modified for each variant.

To people who don’t know better, a doctor is a doctor and a scientist is a scientist, but as journalists plumb the deeper, more involved depths of a new yet specific disease, we bear from time to time a secret responsibility to be constructive and not reductive, and this is difficult. It becomes crucial for us to draw on the wisdom of the right experts, who wield the right expertise, so that we’re moving as much and as often as possible away from the position of what we don’t know we don’t know even as we ensure we’re not caught in the traps of what experts don’t know they don’t know. The march away from complete uncertainty and towards the names of uncertainty is precarious.

Equally importantly, at this time, to make our own jobs that much easier, or at least less acerbic, it’s important for everyone else to know this as well – that more is vastly different.

The virus and the government

In December 2014, public health researchers and activists gathered at a public forum in Cambridge, Massachusetts, to discuss how our perception of diseases and their causative pathogens influences our ideas of what we can and can’t do to fight them. According to a report published in The Harvard Gazette:

The forum prompted serious reflection about structural inequalities and how public perceptions get shaped, which often leads to how resources are directed. “The cost of believing that something is so lethal and fatal is significant,” [Paul] Farmer said.

[Evelynn] Hammonds drew attention to how perceptions of risk about Ebola had been shaped mostly through the media, while noting that epidemics “pull the covers off” the ways that the poor, vulnerable, and sick are perceived.

These statements highlight the importance of a free press with a spine during a pandemic – instead of one that bends to the state’s will as well as doesn’t respect the demands of good health journalism while purporting to practice it.

We’ve been seeing how pliant journalists, especially on news channels like India Today and Republic and in the newsrooms of digital outlets like Swarajya and OpIndia, try so hard so often to defend the government’s claims about doing a good job of controlling the COVID-19 epidemic in India. As a result, they’ve frequently participated – willingly or otherwise – in creating the impression that a) the virus is deadly, and b) all Muslims are deadly.

Neither of course is true. But while political journalists, who in India have generally been quite influential, have helped disabuse people of the latter notion, the former has attracted fewer rebuttals principally because the few good health journalists and the vocal scientists operating in the country are already overworked thanks to the government’s decoy acts on other fronts.

As things stand, beware anyone who says the novel coronavirus is deadly if only because a) all signs indicate that it’s far less damaging to human society than tuberculosis is every year, and b) it’s an awfully powerful excuse that allows the government to give up and simply blame the virus for a devastation that – oddly enough – seems to affect the poor, the disabled and the marginalised too far more than the law of large numbers can account for.

The journalist as expert

I recently turned down some requests for interviews because the topics of discussion in each case indicated that I would be treated as a scientist, not a science journalist (something that happened shortly after the Balakot airstrikes and the ASAT test as well). I suspect science and more so health journalists are being seen as important sources of information at this crucial time for four reasons (in increasing order of importance, at least as I see it):

1. We often have the latest information – This is largely self-explanatory except for the fact that since we discover a lot of information first-hand, often from researchers to whom the context in which the information is valid may be obvious but who may not communicate that, we also have a great responsibility to properly contextualise what we know before dissemination. Many of us do, many of us don’t, but either way both groups come across as being informed to their respective audiences.

2. We’re “temporary experts”.

3. We’re open to conversations when others aren’t – I can think of a dozen experts who could replace me in the interviews I described and do a better job of communicating the science and more importantly the uncertainty. However, a dozen isn’t a lot, and journalists and any other organisations committed to spreading awareness are going to be hard-pressed to find new voices. At this time, science/health journalists could be seen as stand-in experts: we’re up-to-date, we’re (largely) well-versed with the most common issues, and unlike so many experts we’re often willing to talk.

4. It would seem journalists are the only members of society who are synthesising different schools of thought, types of knowledge and stories of ground realities into an emergent whole. This is a crucial role and, to be honest, I was quite surprised no one else is doing this – until I realised the problem. Our scholastic and academic systems may have disincentivised such holism, choosing instead to pursue more and more specialised and siloised paths. But even then the government should be bringing together different pieces of the big picture, and putting them together to design multifaceted policies and inventions, but isn’t doing so. So journalists could be seen as the only people who are.

Now, given these reasons, is treating journalists as experts so bad?

It’s really not, actually. Journalism deserves more than to be perceived as an adjacent enterprise – something that attaches itself on to a mature substrate of knowledge instead of being part of the substrate itself. There are some journalists who have insightfully combined, say, what they know about scientific publishing with what they know about research funding to glimpse a bigger picture still out of reach of many scientists. There is certainly a body of knowledge that cannot be derived from the first principles of each of its components alone, and which journalists are uniquely privileged to discover. I also know of a few journalists who are better committed to evidence and civic duty than many scientists, in turn producing knowledge of greater value. Finally, insofar as knowledge is also produced through the deliberate opposition of diverse perspectives, journalists contribute every time they report on a preprint paper, bringing together multiple independent experts – sometimes from different fields – to comment on the paper’s merits and demerits.

But there are some issues on the flip side. For example, not all knowledge is emergent in this way, and more importantly journalists make for poor experts on average when what we don’t know is as important as what we know. And when lives are at stake, anyone who is being invited to participate in an interview, panel discussion or whatever should consider – even if the interviewer hasn’t – whether what they say could cause harm, and if they can withstand any social pressure to not be seen to be ignorant and say “I don’t know” when warranted. And even then, there can be very different implications depending on whether it’s a journalist or an expert saying “I don’t know”.

Even more importantly, journalists need to be recognised in their own right, instead of being hauled into the limelight as quasi-experts instead of as people who practice a craft of their own. This may seem like a minor issue of perception but it’s important to maintain the distinction between the fourth estate and other enterprises lest journalism’s own responsibilities become subsumed by those of the people and organisations journalists write about or – worse yet – lest they are offset by demands that society has been unable to meet in other ways. If a virologist can’t be found for an interview, a journalist is a barely suitable replacement, except if the conversation is going to be sharply focused on specific issues the journalist is very familiar with, but even then it’s not the perfect solution.

If a virologist or a holist (as in the specific way mentioned above) can’t be found, the ideal way forward would be to look harder for another virologist or holist, and in doing so come up against the unique challenges to accessing expertise in India. In this regard, if journalists volunteer themselves as substitutes, they risk making excuses for a problem they actually needed to be highlighting.
