So-Called COVID Experts had Feet of Clay

The pandemic elevated a particular kind of expert into a position of near-unquestioned authority. Credentialled voices insisted that the science was settled, that trade-offs did not exist or could be ignored, and that dissent was not merely mistaken but morally dangerous. Years later the record looks different. Anthony Fauci's repeated invocation of the Fifth Amendment before a Senate committee is only the most theatrical illustration. Closer to home, Australian academics supplied their own version of the same pattern: confident public assertions that collapsed under scrutiny, followed by silence when the costs became impossible to ignore.

In April 2020 a letter signed by 288 economists informed the Prime Minister and National Cabinet that any suggestion of a trade-off between public health and the economy was a "false distinction." Opportunity cost is the foundational concept of their discipline. They set it aside for the occasion. Twenty-seven days later two of the letter's authors published a cost-benefit calculation that assigned a $1.1 trillion benefit to lockdowns against $180 billion in costs. The distinction they had declared illegitimate was suddenly legitimate once the arithmetic favoured the preferred policy. The modelling rested on extreme assumptions about infection rates and fatality that ignored ordinary human behaviour: people do not continue shopping and dining when they believe death is likely. It also valued lives in a way no ordinary government program does, treating every averted death, many of them among the very old, as a full statistical life. Independent estimates of lives saved were far lower. The letter told the public the question was improper; the subsequent paper answered it.

Those who insisted on proper accounting fared differently. Gigi Foster argued that lockdowns should be assessed the same way governments assess any major intervention, by counting costs and benefits on both sides. She told a Victorian committee that the policy would destroy more life-years than it saved. One set of economists who abandoned their own first principles advanced; the one who applied them became a cautionary tale.

This was not an isolated Australian eccentricity. Across jurisdictions, public-health authorities and their academic supporters framed the crisis as a technical problem with a single correct answer. Modelling that projected catastrophic deaths was elevated; modelling that suggested more modest outcomes or highlighted collateral damage was sidelined. Questions about the origin of the virus, the efficacy of prolonged school closures, the wisdom of vaccine mandates for the young and recovered, or the long-term mental-health and educational costs were treated as threats to social solidarity rather than legitimate lines of inquiry. Official communications emphasised unity and certainty. Private deliberations, when later revealed, often showed more hesitation. The public received the polished version.

The result was a sustained exercise of power that suspended ordinary liberties for extended periods. Borders closed, cities locked down for months, movement restricted by postcode, protest dispersed, employment conditioned on medical status. The experts who endorsed or rationalised these measures rarely faced retrospective accountability. Limited inquiries were carefully scoped to avoid the hardest questions. No large-scale revisiting of the original advice occurred among the signatories of the 288. Debt accumulated, surgeries were deferred, children lost schooling, small businesses closed, and trust in institutions declined. The experts moved on.

The episode does not prove that expertise is worthless. It proves that expertise is human. It is subject to groupthink, career incentives, status competition, and the intoxicating experience of being listened to by politicians under pressure. When the same people who teach trade-offs announce that trade-offs do not apply, when they produce numbers that rest on assumptions they would reject in any other context, and when dissenters are socially punished rather than engaged, the claim to special authority collapses. Blind trust was never wise. The pandemic made the costs of that trust visible. Future crises will again produce confident experts with models and moral certainty. The proper response is not deference but scrutiny: demand the assumptions, the alternative scenarios, the cost side of the ledger, and the willingness to revise when evidence changes. Feet of clay are not a scandal. Pretending they are made of something else is.
