Henry Leveson-Gower reviews results from a recent report that tells how cues from mainstream authority sway economics students even at postgraduate level.
Walk into any economics department and you will hear the same civic promise: this is where students learn to think clearly about how the world works. Models, evidence, disciplined reasoning — an education designed to inoculate against ideology.
But a new report by Mohsen Javdani and Ha-Joon Chang published by Rethinking Economics, puts that promise under a bright, uncomfortable light. Using a randomized controlled experiment with 2,735 economics students across ten countries, the authors test a deceptively simple question: when students evaluate an economic claim, do they respond to the claim itself—or to the status and “mainstream acceptability” of whoever is said to have made it?
The results suggest something many students would deny about themselves: authority matters a lot, often more than students realise.
The experiment
Participants were asked to rate their agreement with 15 statements on contested issues—inequality, globalization, capitalism, methods, power, and the limits of mainstream economics. Everyone saw the same statements.
What changed was the source label attached to each statement. For each statement, students were randomly assigned to one of three conditions:
- mainstream source (the control group);
- less- or non-mainstream source (treatment 1); or
- no source at all (treatment 2).
Because the statements themselves were identical, any systematic shift in agreement can be attributed to the perceived credibility and ideological “fit” of the attributed source — not to the content.
What happened
Across the sample, when a statement was attributed to a less mainstream source, student agreement dropped by about 0.16 standard deviations compared to the mainstream-attributed version. When the source attribution was removed entirely, agreement dropped by about 0.34 standard deviations — more than double the effect.
Those are not trivial effects. They indicate a strong “halo” for mainstream authority — and a penalty either for non-mainstream labels or for the uncertainty of having no authoritative anchor.
The experiment suggests that, whatever students believe about their independence, many are using source cues as a quiet decision rule.
The sharpest irony comes from the students’ own self-description. In follow-up questions, a majority said they judge claims on the substance of the argument, not on who said it. The experiment suggests that, whatever students believe about their independence, many are using source cues as a quiet decision rule.
It goes deeper
If this were simply an early undergraduate phenomenon, departments could shrug: of course first-years lean on authority. But the report finds the opposite pattern. The bias intensifies with progression through the system.
Compared to undergraduates and master’s students, PhD students show markedly larger shifts. Switching to less- or non-mainstream sources reduces agreement far more for PhDs than for earlier-stage students; removing the source altogether also produces a larger drop for PhDs.
The most plausible explanation is structural rather than personal. As students move into the professional pipeline—supervisors, journals, job markets, reputational gatekeeping—conformity stops being a background pressure and becomes a career strategy. If your future depends on being seen as “serious,” you learn quickly which signals to follow.
Politics matters
The report also explores how authority bias interacts with political orientation. Among PhD students, the penalty for non-mainstream attribution grows as students move from left to right. Centre- and right-leaning PhD students show some of the strongest negative shifts in agreement when the source is less-/non-mainstream or absent.
This is not a moral judgement about students’ politics. It is about how a discipline’s internal hierarchy interacts with ideology.
This is not a moral judgement about students’ politics. It is about how a discipline’s internal hierarchy interacts with ideology: if mainstream economics is perceived (rightly or wrongly) as aligned with certain policy instincts, those already closer to that worldview may be more inclined to treat mainstream authority as epistemic authority.
Gender differences
The report finds a consistent gender gap. Male students show stronger shifts than female students when sources change—both when statements are attributed to less-/non-mainstream figures and when attribution is removed altogether.
These differences persist even when accounting for political ideology, suggesting something more structural about how students are socialised inside the discipline—and about who is rewarded for projecting certainty and deference to orthodox signals.
Most people assume the bias will show up mainly as “I trust famous economists.” The experiment suggests something slightly different: students may be trained to need a legitimising badge at all. When the source label disappears, agreement falls even more than when a non-mainstream label appears.
That points to a discipline where ideas are not simply debated—they are validated by institutional cues.
The bigger issue
The report’s argument is ultimately about competence, not classroom culture wars. If economics education trains students to defer to authority and to filter ideas through perceived “mainstream” alignment, then whole categories of insight become hard to absorb—even when reality demands them.
A discipline that narrows what counts as credible knowledge is likely to be slow, defensive, and brittle when its models underperform.
That matters in a century defined by problems that do not respect tidy assumptions: ecological limits, rentier power, care and unpaid labour, financial instability, supply-chain fragility, inequality, and political breakdown. A discipline that narrows what counts as credible knowledge is likely to be slow, defensive, and brittle when its models underperform.
The authors position pluralism—serious engagement with multiple schools of thought, methods, and framings—not as a feel-good add-on, but as a requirement for a discipline that wants to learn.
Change needed
If departments take these findings seriously, the response cannot be limited to a single “history of thought” lecture or a week on heterodox approaches. The bias the report documents is shaped by signals students absorb over years: what is rewarded, what is publishable, what is employable.
At minimum, that implies changes in three places:
- Curriculum: treat competing frameworks as live options for explanation, not museum pieces.
- Methods training: teach model critique, uncertainty, and the limits of identification alongside techniques.
- Incentives: broaden what counts for hiring, promotion, and doctoral success beyond narrow journal hierarchies.
None of this requires abandoning mathematics or evidence. It requires remembering what those tools are for: understanding the world, not defending a professional identity.
In the end, the report’s message is less about student psychology than about institutional design. If economics wants to keep its claim to public authority, it needs a training culture that makes independent judgement possible—not one that quietly teaches deference.
If this finding holds, the challenge for economics departments is straightforward and brutal: it is not enough to add a token “alternative approaches” week. The problem is embedded in incentives, career structures, and the everyday signalling of what counts as “real economics.”
