The research team focused on three sectors that contribute substantially to greenhouse gas emissions and where individual behaviour change can have the greatest impact: energy use in the home, transport choices, and food consumption. These are also the sectors in which international policy learning and transfer are most common, as governments routinely borrow instruments that have succeeded elsewhere, from carbon taxes to appliance efficiency standards. The problem, the authors argue, is that such transfers often rest on an implicit assumption that populations behave alike, or that a handful of socio-demographic characteristics such as age, income and education can stand in for actual behavioural patterns. When those assumptions fail, policies underperform and public money is wasted.

To test these assumptions rigorously, the researchers employed Multilevel Latent Class Analysis, a statistical technique that identifies unobserved groups of people who share similar behavioural profiles without the analyst predefining what those groups should look like. The multilevel structure of the method is crucial: it simultaneously classifies individuals and accounts for the fact that those individuals are nested within regions and countries, allowing the team to detect both the behavioural segments themselves and the way those segments are distributed geographically. Applied to the survey data, the technique revealed distinct population segments in each of the three sectors, ranging from highly sustainable to markedly unsustainable patterns of behaviour.

The headline finding is sobering. Less sustainable behavioural patterns were prevalent across all three sectors in every country examined, meaning that in energy, transport and food alike, the largest or most common groups of people exhibited relatively unsustainable habits. Yet the picture was not uniformly bleak, and it was certainly not uniform. The energy sector in particular displayed notable heterogeneity, with a wider variety of behavioural profiles than the other two sectors. This suggests that household energy behaviour is shaped by a more diverse set of circumstances, practices and constraints than, say, dietary choices, and that energy policy may therefore require finer targeting than policies aimed at transport or food.

Perhaps the most consequential result for policy design is what the study found about socio-demographics. Conventional segmentation approaches, which sort people by income bracket, education level or age cohort, assume these characteristics reliably predict environmental behaviour. The analysis showed that they do not, at least not consistently. Socio-demographic characteristics failed to predict segment membership reliably across countries and sectors, undermining a foundation on which much targeted policy communication rests. A wealthy, highly educated urbanite in one country may fall into a profligate energy-use segment, while a demographically similar person elsewhere may be among the most sustainable. If policymakers cannot infer behaviour from demographics, they need direct behavioural evidence, which is precisely what latent class methods provide.

The study also uncovered a striking pattern of behavioural consistency within individuals. People who engaged in sustainable behaviours in one sector were more likely to do so in the others, and, symmetrically, unsustainable behaviours were positively associated across sectors as well. In other words, environmental behaviour tends to cluster within people rather than existing in isolated silos. This has an important implication: interventions that successfully shift behaviour in one domain may create momentum in others, and coordinated cross-sector interventions are likely to be more effective than sector-by-sector campaigns. A household that adopts efficient heating may be more receptive to messages about low-carbon travel or reduced meat consumption, and policies that treat these domains together could exploit that correlation.

Geography turned out to matter enormously. When the researchers mapped the regional distribution of population segments, they found that regions typically grouped geographically by country, underscoring the influence of national context such as policy regimes, infrastructure, culture and climate on environmental behaviour. People in the same country tend to share a behavioural profile mix, which is exactly what makes national policy learning plausible. But the more surprising discovery lay beneath that national clustering: significant within-country variation. Some regions showed substantially different proportions of people in sustainable segments than their neighbours, despite operating under identical national policies. A region can be a behavioural outlier within its own country, hosting far more or far fewer sustainably behaving residents than the national policy environment alone would predict.

This within-country variation is where the study makes its most practical contribution. Traditional policy transfer is often ad hoc: a government observes that a scheme works in another country and imports it, hoping for similar results. Yang and colleagues propose instead a systematic framework for identifying evidence-based transfer opportunities. The framework answers three questions in sequence: who needs interventions, in the form of which population segments are prevalent and unsustainable in a given region; where successful patterns emerge, by locating regions with unusually high concentrations of sustainable segments; and which contexts may enable sustainable behaviours, by comparing the conditions of successful regions with those where unsustainable segments dominate. In effect, the method turns the map of behavioural segments into a targeting tool, directing policymakers to the places where a given intervention is most likely to find receptive conditions.

The technical machinery behind this framework deserves emphasis, because it is what elevates the study beyond a descriptive survey. Multilevel Latent Class Analysis avoids the arbitrariness of hand-drawn segments by letting the data define the behavioural classes, while its hierarchical structure prevents the ecological fallacy of treating national averages as if they described individuals. By estimating segment prevalence separately for each of the 61 regions, the method produces a granular behavioural geography that neither national surveys nor purely local studies can deliver. The cross-national design then allows genuine comparison: a region can be judged not only against its own country but against the full range of OECD contexts in the dataset, revealing whether its behavioural mix is typical, exceptional, or transferable.

The implications reach well beyond the nine countries studied. As governments race to meet climate targets, behaviour change in energy, transport and food is widely recognised as essential to achieving mitigation at the scale and speed required, yet it remains one of the least systematically measured dimensions of climate policy. This study demonstrates that the raw material for smarter policy already exists in large international surveys, and that sophisticated but well-established statistical methods can convert that data into actionable maps. The message for the international policy community is twofold: stop assuming that populations are homogeneous or that demographics predict behaviour, and start using evidence about who behaves unsustainably and where enabling contexts exist. If policy transfer is to deliver on its promise, it must begin not with a successful scheme in search of a home, but with a rigorous account of the people and places it is meant to serve.

The paper, published in the journal AI & Society by Masaya Ochiai, an independent researcher based in Nagoya, Japan, introduces a method called the normative translation audit, or NTA. Rather than treating AI ethics principles as fixed ideas that either spread or fail to spread, the framework treats them as material that is inevitably transformed as it moves between organizations, jurisdictions, and regulatory levels. The central claim is that comparative research on AI ethics has a structural blind spot: when analysts compare Asian frameworks against European or American ones, they often end up measuring deviation from a Western baseline rather than understanding how norms actually work within and between Asian societies.

Ochiai names this blind spot reference-point drift. The problem arises, he argues, when Euro-American frameworks silently become the reference point for comparison. In that situation, intra-regional comparison among Asian countries degenerates into deviation scoring: a framework is judged as more or less aligned with the OECD recommendation, the NIST AI Risk Management Framework, or the EU’s Assessment List for Trustworthy Artificial Intelligence, rather than being analyzed on its own terms. This matters because Asia contains enormous internal plurality, spanning vastly different political systems, legal traditions, and levels of AI development, while at the same time being tightly interconnected through cross-border data flows, supply chains, and regional institutions such as ASEAN. A comparison method that can only ask how closely a country matches a Western template cannot jointly handle that internal diversity and external interdependence.

The intellectual machinery behind the argument draws on established scholarship in policy transfer and norm diffusion. Ochiai cites work on norm localization in Asian regionalism, studies of how international human rights law is translated into local justice, and the sociology of standards, which shows that standardization is never a neutral technical act but a process that reorganizes social relationships. He also draws on the audit society literature, which describes how modern institutions increasingly rely on rituals of verification, and on critiques showing that principles alone cannot guarantee ethical AI. The recurring theme is translation: a principle such as fairness does not simply arrive intact in a new jurisdiction. It is redefined, reweighted, and re-embedded in local institutional arrangements, and those transformations are where governance actually happens.

To make these transformations visible, NTA redesigns the unit of comparison. Instead of comparing principle vocabularies, the method focuses on four branch points that determine practical governance outcomes. The first is operational definitions: how a principle like transparency or fairness is concretely specified, what counts as compliance, and what technical measures are named. The second is veto rights: who has the authority to stop or block an AI deployment, and under what conditions. The third is remedy lines: what channels exist for people harmed by an AI system, what compensation or correction is available, and who bears the burden of proof. The fourth is accountability assignment: which actors, institutions, or roles are held answerable when systems fail, and how that answerability is enforced.

These four branch points function as a diagnostic grid. Two jurisdictions may both endorse accountability in their official documents, yet one may assign it to a voluntary industry review board while the other embeds it in a statutory regulator with sanctioning powers. Vocabulary-based comparison would score both as aligned; branch-point comparison would reveal a divergence with real consequences for affected people. Similarly, the veto-rights branch point distinguishes frameworks in which civil society or affected communities can formally contest a deployment from those in which contestation is limited to internal corporate review. The remedy branch point captures whether harms trigger compensation, correction, or merely documentation. By fixing the comparison unit at these decision-relevant junctures, NTA aims to prevent the silent drift back to Western baselines.

NTA is deliberately positioned as a minimal procedure rather than a full compliance audit. Ochiai is explicit that it is not a pass/fail certification and not third-party assurance in the style of financial or security audits. Its purpose is narrower and more methodological: to fix comparison units before analysis begins and to trace whether register updates, meaning documented changes in how principles are specified, actually changed decisions in specifications, operations, or remedy design. The method requires three artifacts. The first is a Branch Register, a structured record of how each framework under study resolves each of the four branch points. The second is a Decision-Change Log, which tracks whether updates to that register corresponded to changes in actual decisions. The third is a multi-anchor memo, which documents which external frameworks were selected as comparison anchors and, crucially, which were excluded, so that no single external framework becomes the only baseline against which everything else is measured.

The paper includes a brief demonstration using the Association of Southeast Asian Nations and Singapore, drawing on the ASEAN Guide on AI Governance and Ethics, its 2025 expansion covering generative AI, and Singapore’s Model AI Governance Framework. The demonstration illustrates how branch-point comparison surfaces divergences, particularly around contestation and decision review, that vocabulary-based comparison tends to hide. Where a word-level analysis might conclude that ASEAN and Singaporean documents broadly echo global principles on transparency and human oversight, examining who can contest decisions and how reviews are triggered reveals a more textured picture of how responsibility is distributed across regional guidance and national implementation. The author presents this as an illustration rather than a completed empirical test, and the paper outlines a testable protocol, including a minimal coding sheet with fields for anchor identity, branch point, evidence locators, confidence levels, and disagreement flags for double-coded entries, for future studies to evaluate the method empirically.

The significance of the proposal extends beyond academic comparison. As AI regulation matures worldwide, regulators and companies increasingly benchmark their frameworks against one another, and the choice of benchmark shapes what counts as progress. If Asian frameworks are always scored against European or American templates, the analysis risks reproducing what postcolonial scholars have long criticized: the subaltern perspective is heard only insofar as it echoes the metropole. NTA’s multi-anchor requirement is a direct response to that risk. By forcing analysts to document anchor selection and exclusion, the method makes the politics of comparison explicit and creates space for intra-Asian baselines, such as ASEAN regional guidance, to serve as legitimate reference points in their own right.

The paper also arrives amid a broader wave of scholarship questioning whether the global AI ethics movement has delivered on its promises. Large-scale analyses of ethics guidelines have shown substantial convergence in stated principles alongside persistent disagreement about implementation, and researchers have documented how abstraction in sociotechnical systems can hollow out fairness commitments when they meet real-world engineering constraints. NTA contributes to this conversation by shifting attention from what frameworks say to what their words do: how they define, who they empower to block, what they promise the harmed, and whom they hold to account. Whether the method proves robust in empirical use remains to be tested, but it offers researchers and policymakers a concrete toolkit for asking a deceptively simple question with large consequences: when an AI ethics principle crosses a border, what exactly changes, and who benefits from the change?

The study tackles a persistent puzzle in comparative education. Scholars have long attributed the global surge of private higher education either to supra-national pressures, such as the influence of international organizations and global markets, or to domestic dynamics, such as rising demand and shrinking state budgets. Neither explanation, the authors argue, actually traces the process by which ideas about private provision move: who carries them, through which networks, in what form, and how they change in transit. To fill that gap, the researchers combined two analytical tools. The first is the Glonacal agency heuristic, originally developed by Simon Marginson and Gary Rhoades and updated by Marginson in 2022, which directs attention to the global, national, and local scales at which actors exercise agency. The second is the policy mobility concept from economic geography, associated with Jamie Peck and Nik Theodore, which treats policies not as fixed models that get copied but as mobile assemblages that mutate as they travel.

Vietnam makes an ideal laboratory for this question. After the economic reforms known as Doi Moi launched in 1986, the country, still governed by a single ruling party, gradually reopened space for non-state actors in a sector that had been almost entirely public. Two distinct policy trajectories emerged over the following decades. The first was the emergence of generic private higher education, meaning non-state provision of any kind. The second was the later evolution of a specific nonprofit form of private higher education, an idea imported more deliberately and codified in law. By following both trajectories across spaces and through time, the researchers could compare what happens when ideas arrive as vague imaginaries versus when they arrive attached to concrete legal models.

The empirical work was unusually demanding. The team assembled archival policy documents spanning decades, collected autobiographical narratives from figures who lived through the founding era of Vietnamese private universities, and conducted 47 elite interviews with the policymakers, institutional founders, and advisers who shaped the sector. Elite interviewing of this kind, a method discussed extensively in the policy literature, requires access to once-powerful actors whose decisions are otherwise poorly documented, and retrospective accounts must be triangulated against the documentary record. The resulting dataset allowed the researchers to reconstruct not just what policies said, but who proposed them, which foreign references they invoked, and how those references were understood or misunderstood by different factions within the Vietnamese state.

The first major finding concerns the nature of what travels. In both the generic and nonprofit cases, transnational policy actors, including international organizations, foreign-educated technocrats, and transnational academic networks, played decisive roles in bringing private higher education ideas into Vietnam. But those ideas did not arrive as coherent, ready-made models. Instead, they arrived as what the authors call partial and unsystematic imaginaries: fragmented visions of what private higher education might be, drawn from heterogeneous foreign examples and filtered through the imaginations of the carriers. A legal text or a study tour might convey a silhouette of the American private university or the Japaneseorporatized institution, but the underlying institutional logic, financing structures, and governance arrangements rarely traveled with it.

In the generic private higher education case, those fragmentary imaginaries were then further mutated by domestic factional politics. Rather than producing a single national model, the collision of partial foreign visions with internal competition among policy factions generated what became known in Vietnam as the people-founded university, a distinctive institutional form unlike the private universities of liberal market economies. Institutions established under this banner developed divergent practices across the country, with some behaving like family businesses, others like quasi-public extensions, and others like commercial enterprises. The study shows that this institutional heterogeneity was not an accident of weak regulation but a direct product of how mobile ideas, only partially understood, were renegotiated inside a factionalized state apparatus.

The nonprofit trajectory tells an even more instructive story. Here, the actors promoting the policy included people with first-hand experience of the same reference model, individuals who had studied or worked within actual nonprofit institutions abroad. One might expect that shared experiential grounding would produce a unified vision. Instead, the researchers found that even these actors promoted divergent versions of what nonprofit private higher education should mean in the Vietnamese context, differing on questions of governance, asset ownership, and the distribution of surpluses. And crucially, when the nonprofit idea was finally codified into Vietnamese law, a genuine legislative success, the legal text failed to generate the corresponding social practices. Institutions did not reorganize themselves around the nonprofit form in the ways the statute envisioned, revealing a stubborn gap between codification and everyday institutional behavior.

These findings lead the authors to two conceptual contributions. First, in the updated Glonacal framework, Simon Marginson distinguished three spatial dimensions of agency: imagined space, where actors conceive of possibilities beyond their immediate context; material space, where resources and institutions are physically organized; and social practice space, where everyday routines and behaviors actually unfold. The Vietnamese evidence shows that these three spaces interact sequentially rather than simultaneously. Imagined spaces, populated by foreign imaginaries, opened first; material spaces, such as new legal categories and institutional buildings, followed; and social practice spaces lagged far behind, sometimes indefinitely. Policy mobility, in other words, is not a single moment of transfer but a staggered process in which each spatial dimension operates on its own timescale.

Second, the study characterizes Vietnam’s one-party state as an asymmetric gatekeeper in the global circulation of education policy. The state can effectively control which transnational ideas get codified into law, filtering, editing, and domesticating foreign models before they enter the statute books. But codification is where its gatekeeping power ends. The same state apparatus cannot conjure the societal practices that its own legislation envisions, because practices emerge from the incentives, histories, and strategies of thousands of institutional actors, not from legal text alone. This asymmetry, between the power to legislate and the inability to command social practice, complicates common images of authoritarian states as all-powerful policy adopters and suggests that even tightly controlled political systems are porous to, and transformed by, transnational ideas they cannot fully steer.

For a world in which private higher education continues to expand, particularly across Asia, Africa, and Latin America, the Vietnamese case carries a sobering lesson. Exporting a legal model, however carefully drafted and however experienced its promoters, does not transplant the institution itself. What crosses borders most readily are imaginative fragments, and what those fragments become depends on the factional politics, gatekeeping structures, and sequencing of spaces in the receiving country. The research, funded by the Vietnam National Foundation for Science and Technology Development, demonstrates the analytical payoff of pairing the Glonacal heuristic with processual policy mobility tools, and it reframes the worldwide rise of private higher education not as the diffusion of a model but as the ongoing, uneven mutation of an idea, one national story at a time.
