Something has shifted in the way people relate to knowledge. Scientists, doctors, economists, and public health officials who once commanded broad social authority now find themselves dismissed, ridiculed, or simply ignored by significant sections of the population. This is not merely a political phenomenon, nor is it the result of widespread irrationality. The crisis of expertise is a sociological problem — one rooted in changing institutional structures, shifting patterns of trust, and the transformation of the information environment in which we all now live.

Understanding why trust in expertise has eroded — and why it has eroded unevenly across different social groups — requires moving beyond simple explanations. It is not enough to say that people have been misled by social media, or that populist politicians have cynically exploited anti-intellectualism. While both of these factors matter, they do not fully account for the structural conditions that made such a crisis possible in the first place. Sociology offers a more complete picture.

What Is Expertise and Why Did We Ever Trust It?

Expertise refers to a socially recognised form of specialised knowledge — knowledge that is validated not simply by one person’s claim to it, but by institutions, credentials, and professional communities. A doctor is not an expert because they say so; they are an expert because they have passed through a formal system of training, examination, and licensing that society has agreed to recognise as authoritative. This social validation is the foundation of expertise as we know it.

The sociologist Max Weber was among the first to analyse this phenomenon systematically. Weber argued that modern societies are characterised by a process he called rationalisation — the increasing organisation of social life around formal rules, procedures, and technical knowledge rather than tradition or personal charisma. In a rationalised society, bureaucratic institutions and credentialed experts become the legitimate sources of authority. We trust the bridge engineer not because we know them personally, but because we trust the system of qualifications and professional oversight that produced them.

This form of trust is sometimes called system trust or abstract trust — trust placed not in individuals but in the abstract systems they represent. The sociologist Anthony Giddens made this distinction central to his account of modernity, arguing that modern life depends on a constant, largely unconscious faith in expert systems that most of us do not and cannot fully understand. When you board a plane, you trust aviation engineering. When you take medication, you trust pharmacology and regulatory science. This delegation of judgement to expert systems is not naivety — it is a rational response to the complexity of modern life.

The Sociological Roots of Distrust

If system trust is a fundamental feature of modernity, why is it breaking down? The answer is not that people have become irrational, but that the social conditions which sustain trust have themselves been destabilised.

Institutional Failure and Broken Promises

Trust in institutions is not unconditional — it must be earned and periodically renewed through performance. When institutions consistently fail the people they are supposed to serve, trust erodes. The 2008 financial crisis is a paradigmatic example. Mainstream economists, financial regulators, and government advisors — all credentialed experts operating within recognised institutional frameworks — failed to prevent, and in some cases actively contributed to, a catastrophic economic collapse. Millions of people lost their homes, jobs, and savings while many of the experts responsible faced few serious consequences.

Similar failures can be identified in public health, where expert institutions have sometimes issued advice that was later reversed; in criminal justice, where professional judgements have contributed to wrongful convictions; and in social policy, where expert-designed interventions have repeatedly produced unintended harms in working-class and minority communities. From a sociological perspective, it would be strange if these failures did not generate scepticism. Distrust of expertise is not always irrational — it can be a learned response to a history of being let down.

Class, Inequality, and the Politics of Who Gets Trusted

The crisis of expertise does not affect all social groups equally, and this unevenness is itself sociologically significant. Research consistently shows that scepticism towards expert institutions tends to be higher among people with lower incomes, lower levels of formal education, and in communities that have experienced prolonged economic decline. This is not coincidental.

Pierre Bourdieu’s concept of cultural capital helps explain the relationship between social position and orientation towards expertise. Formal education does not simply transmit knowledge — it instils familiarity with, and deference towards, the norms and authorities of the dominant culture. Those who have accumulated higher levels of cultural capital through education and class position are more likely to feel at home in expert discourse, to know how to engage with it, and to benefit from it. Those who have not are more likely to experience expert institutions as alien, condescending, or simply irrelevant to their actual lives.

There is also a straightforward material dimension to this. Expert advice on diet, mental health, financial planning, and education tends to be far easier to act on if you have economic resources. When experts recommend interventions that are inaccessible to people on low incomes, those people are not simply ignoring expert guidance — they are recognising its limits for their actual situation. Distrust, in this context, can function as a form of practical wisdom.

The Digital Information Environment and the Collapse of Epistemic Authority

The structural conditions described above created fertile ground for distrust. But the transformation of the information environment over the past two decades has dramatically accelerated the crisis. The internet, and social media in particular, has disrupted the institutional gatekeeping through which expert knowledge once reached the public.

In the twentieth century, the flow of expert knowledge to the public was mediated by a relatively small number of institutions — broadcasters, newspapers, publishers, and professional bodies — that exercised editorial judgement about what counted as credible information. This gatekeeping was imperfect and often served the interests of powerful groups, but it did impose a form of epistemic discipline: fringe claims had to pass through relatively robust filters before reaching mass audiences.

Digital platforms have dismantled this architecture. Anyone can now publish to a global audience without passing through editorial or peer-review processes. Algorithmic content distribution rewards engagement over accuracy — content that provokes emotional responses spreads further and faster than content that is careful, nuanced, or complex. In this environment, a charismatic amateur with a compelling counter-narrative can build an audience comparable in size to that of credentialed institutions, with no mechanism to evaluate the relative quality of their claims.
