The research was conducted by Ge Wang, Haixin Teng, and Zengyang Xu of the School of Public Administration at Central China Normal University in Wuhan, and it addresses one of the most persistent blind spots in the study of algorithmic governance. Scholars have long argued that automation transforms street-level bureaucracy, echoing Michael Lipsky’s classic insight that frontline workers are the ultimate policymakers because they exercise discretion in every individual encounter. Earlier work by Bovens and Zouridis described a drift from street-level to system-level bureaucracy, in which decision-making migrates from human judgment to automated systems. But the new study asks a sharper question: what happens to how bureaucrats enforce — not just what they decide — when AI enters the loop, and how does felt accountability reshape that relationship?

To answer it, the team designed a preregistered survey experiment embedded in the real-world context of honking violations, a common and familiar enforcement scenario for traffic police. Participants were 356 street-level police officers drawn from a representative sample, making this one of the more methodologically robust attempts to measure enforcement style directly among practitioners rather than students or hypothetical respondents. Invalid questionnaires were excluded before hypothesis testing, based on substantial missing data, incomplete experimental responses, or failure to pass embedded attention-check items, and the experimental design was preregistered to guard against selective reporting. Data supporting the findings are available from the corresponding author upon reasonable request, and the preregistration is publicly archived on the Open Science Framework.

The experiment crossed two manipulations: whether officers received AI support in the enforcement scenario, and which type of accountability they experienced. In public administration, accountability is conventionally divided into process accountability, where officials must justify the procedures and reasoning behind their decisions, and outcome accountability, where they are judged by the results those decisions produce. Decades of psychological research, from Tetlock onward, have shown that these two forms of felt accountability trigger distinct information-processing strategies, often in opposite directions. The Chinese enforcement context makes the setting particularly instructive, given its documented history of campaign-style enforcement and shifting regulatory styles among frontline officials.

The core findings are cleanly delineated. AI-supported enforcement, on its own, pushed officers toward a more formal and coercive style of enforcement — rule-invoking, sanction-first, procedural — while weakening the educational component, the practice of explaining, persuading, and teaching violators why compliance matters. This matters because enforcement style is not cosmetic. A substantial body of regulatory scholarship, including work by May and Wood on inspectors at the regulatory front lines and by Braithwaite and colleagues on enforcement pyramids, links style directly to compliance outcomes, citizen trust, and the legitimacy of the state. A coercive turn among officers algorithmically nudged into formalism could therefore ripple outward into how millions of daily encounters between citizens and the state actually feel.

Accountability, meanwhile, produced effects of its own that align closely with prior experimental literature. Officers who felt process accountability gravitated toward a more educational, prioritization-focused, and accommodative enforcement style — they reasoned more about how and why they enforced, reserved harsh measures for the cases that mattered most, and left more room for discretion and dialogue. Officers under outcome accountability moved in the opposite direction, reinforcing a more formal and coercive posture, consistent with the idea that being judged purely on results encourages defensive, box-ticking enforcement designed to be blame-proof.

The most consequential and arguably most surprising result is the interaction. Process accountability did not buffer officers against the algorithmic push toward formalism and coercion; it intensified it. Under process accountability, the presence of AI support further reinforced formal and coercive enforcement while further weakening the educational approach. The authors’ interpretation, grounded in the combined-effects framework they develop, is that when officers must justify their processes, the documented, auditable recommendation of an algorithm becomes an attractive anchor — a defensible procedural basis for action. Following the machine feels procedurally safe, and in doing so officers may shed the relational, educative practices that algorithmic systems cannot capture or document. The accountability mechanism designed to make officers more thoughtful may, in the presence of AI, make them more mechanical.

These findings carry immediate implications for governments racing to deploy AI in policing, from automated violation detection to algorithmic risk assessment and case triage. The study suggests that technology procurement and accountability reform cannot be designed in isolation. An agency that pairs algorithmic enforcement tools with process-oriented oversight — often considered the ethically preferable arrangement — may inadvertently deepen the very dehumanization of frontline encounters that critics of algorithmic governance fear. Conversely, outcome accountability’s independent drift toward coercion compounds the problem. If policymakers want AI to augment rather than hollow out street-level discretion, the results imply that accountability frameworks must be engineered to explicitly protect and incentivize the educational, judgment-rich dimensions of enforcement that machines neither practice nor document.

The study also speaks to a growing theoretical conversation about artificial discretion — the hybrid of human and machine judgment described by Young, Bullock, and Lecy — and about why bureaucrats trust AI recommendations, with recent experimental work suggesting that confirmation of professional judgment drives algorithmic acceptance. By demonstrating that enforcement style is a joint product of technology and institutional design, the Chinese policing experiment moves the field beyond the simple question of whether bureaucrats accept algorithmic advice toward the richer question of what they become when they do. As cities worldwide wire AI into everything from traffic cameras to welfare fraud detection, the transformation of the frontline worker may prove to be the most important, and least visible, policy outcome of the algorithmic state.
