Public trust in expertise has become one of the defining anxieties of our time. Climate scientists issue warnings that a significant portion of the population dismisses. Economists make forecasts that are routinely contradicted by events. Medical authorities offer guidance that is accepted by some and furiously resisted by others. The sociologist Gil Eyal has observed that we inhabit a paradoxical moment in which society depends on expert knowledge more completely than ever before, yet treats it with a suspicion that would have been largely unthinkable a generation ago. Understanding how this situation arose — and whether it can be resolved — requires a willingness to examine not only the failings of the public but also the failings of expertise itself.
The most frequently offered explanation for the decline in trust is the democratisation of information. The internet has given every individual access to a volume of data that was once the preserve of specialists, creating the illusion that expertise is no longer necessary. A parent who spends an evening reading about vaccine ingredients online may feel as informed as the immunologist who has spent a career studying the subject. The philosopher Tom Nichols has argued that this phenomenon represents not genuine democratisation but a collapse of the distinction between informed and uninformed opinion — a levelling that treats all claims as equally valid regardless of the evidence and training behind them.
There is considerable force in this analysis, but it risks placing the blame entirely on the public while absolving experts and the institutions that house them. The history of expertise is not one of unbroken reliability. Economists failed to predict the financial crisis of 2008. Nutritional scientists spent decades promoting dietary advice that was subsequently reversed. Intelligence agencies presented flawed assessments that contributed to catastrophic policy decisions. These are not obscure examples; they are episodes that eroded public confidence for reasons that are entirely rational. When experts are wrong about matters of great consequence, the public's scepticism is not ignorance — it is an appropriate response to a demonstrated track record of fallibility.
The problem is compounded by the way expertise intersects with politics and commercial interests. Pharmaceutical companies fund research that tends to favour their products. Think tanks that present themselves as independent often receive funding from organisations with specific policy agendas. The revolving door between regulatory bodies and the industries they are supposed to oversee creates conflicts of interest that are visible to anyone paying attention. In such an environment, the instruction to 'trust the experts' is not merely insufficient; it is naive, because it fails to acknowledge that the institutional contexts in which expertise operates are themselves sources of systematic distortion.
None of this justifies the wholesale rejection of expert knowledge. The alternative to imperfect expertise is not popular intuition but worse outcomes: more disease, more environmental damage, more economic instability. What is needed is a more honest relationship between experts and the public — one in which experts communicate not only their conclusions but also their uncertainties, their methods, and the limitations of their knowledge. The philosopher of science Heather Douglas has argued that trustworthy expertise requires transparency about the values and assumptions embedded in scientific judgements, particularly when those judgements inform policy decisions that affect millions of people.
Building this kind of trust is not a task for experts alone. It requires institutional reforms that reduce conflicts of interest, media practices that distinguish between genuine scientific disagreement and manufactured controversy, and an educational system that teaches not deference to authority but the skills of critical evaluation — the ability to assess evidence, identify reliable sources, and recognise the difference between healthy scepticism and conspiratorial thinking. The goal is not to restore a golden age of uncritical trust that almost certainly never existed, but to construct a more mature and resilient relationship between knowledge and democracy — one that neither idolises expertise nor dismisses it, but holds it to the high standards it claims for itself.
