Circularity is the second structural argument in Politics and Markets — the companion to the privileged position of business. It describes how corporate interests shape not only policy outcomes but the preferences citizens form, through control of media platforms, funding of research, employment of former regulators and academics, and the cultural production that shapes public understanding. Democratic theory assumes that citizens form preferences independently and express them through political channels. Lindblom argued that in market democracies, the preferences themselves are substantially shaped by the corporate interests that democratic processes are supposed to check. The check is compromised because the preferences being aggregated are already biased toward the interests the check is meant to constrain.
The AI case operates with particular force. The public discourse about AI is substantially shaped by AI companies: through research publications, product demonstrations, media relations, academic funding, employment of former regulators, and the platforms on which the discourse itself takes place. The citizens whose democratic preferences are supposed to guide AI governance are forming those preferences within an information environment substantially controlled by the companies to be governed.
This is not conspiracy. It is architecture. When the firms with the greatest stake in AI policy also control the infrastructure through which AI policy is discussed, the resulting preferences reflect the interests of those firms more than democratic theory assumes. The citizens are not lied to. They are presented with a selection of information that foregrounds certain considerations and backgrounds others, and the selection is made by parties with specific stakes in the outcome.
The circularity compounds the privileged position. The privileged position gives firms structural leverage over governments. The circularity gives firms structural leverage over the citizens whose preferences governments are supposed to represent. Together, they produce a system in which democratic correction of corporate power requires citizens to hold preferences that run counter to the preferences the corporate system has shaped them to hold.
The response is not despair but institutional counterbalance. Public AI research capacity that operates independently of industry funding. Public media infrastructure that is not dependent on industry advertising. Educational frameworks that equip citizens to evaluate industry claims critically. Regulatory bodies with technical competence sufficient to generate independent analyses. Each is an incremental intervention. Each addresses a specific mechanism of circularity. None eliminates the structural problem, but together they reduce its severity enough that democratic correction becomes possible.
Lindblom developed the concept in Politics and Markets (1977) as the second leg of his structural analysis of corporate power. He extended it in The Market System (2001) with greater emphasis on the specific mechanisms through which the circularity operates — mechanisms that the rise of digital platforms has intensified in ways Lindblom did not live to see fully developed.
Preference formation. Democratic theory assumes citizens form preferences independently; Lindblom argued preferences are shaped by the same interests they are supposed to check.
Mechanisms of circularity. Media ownership, research funding, employment of former regulators, and platform control are among the specific mechanisms through which the circularity operates.
AI-era intensification. Digital platforms and AI-generated content dramatically intensify the mechanisms Lindblom identified, shifting more of the information environment under the control of the firms whose activities are most consequential.
Institutional counterbalance. The response is not to abolish corporate media but to build institutional counterweights — public research capacity, independent journalism, technically competent regulation.
