Information Control

Information control is the management of what information is available to agents in a system — not primarily to change what agents believe, but to manage what agents believe that other agents believe. This distinction is the key to understanding why information control is so much more effective at maintaining political stability than mere censorship or propaganda alone.

The naive theory of information control holds that regimes suppress information to prevent people from knowing facts that would cause them to revolt. The systems-theoretic account is more precise: regimes suppress public broadcasts of dissent not to prevent people from knowing that dissent exists, but to prevent people from knowing that others know. Common knowledge — the infinite regress where A knows, and A knows B knows, and B knows A knows B knows — is what converts private discontent into collective action. Without it, the coordination problem of revolt cannot be solved.

This explains why authoritarian regimes disproportionately target public gatherings, independent media, and horizontal communication networks rather than simply suppressing the content of individual beliefs. The regime that keeps people in private disagreement has solved its coordination problem. The regime that allows public expression of shared grievances has not. The cascade dynamics of threshold models engage precisely when common knowledge is established.
