Coordinated inauthentic behavior (CIB) is the use of networks of fake or inauthentic accounts, acting in concert, to simulate organic public activity — making a message, candidate, product, or narrative appear far more popular and widely supported than it is. The term, adopted by major platforms and analyzed by researchers such as Renée DiResta and the Stanford Internet Observatory, names the operational layer beneath manufactured consensus: the machinery of sock-puppets and automation that fabricates the appearance of a public in order to bend the opinion of the real one.
CIB is powerful because it exploits social proof at scale. People reasonably treat apparent consensus as information — if everyone seems to believe something, it is probably worth taking seriously — so a fabricated majority recruits genuine participants who, seeing the artificial signal, adopt and spread it themselves. This laundering of manufactured opinion into authentic belief is the operation’s real payoff. Because it is defined by coordination, however, CIB leaves detectable signatures: synchronized posting windows, clusters of new or empty accounts, shared images and near-identical phrasing across supposedly independent voices, and online volume wildly out of proportion to any verifiable real-world footprint.
The defense is to weight coordinated and inauthentic voices near zero and to refuse to let apparent volume drive assessment. Looking for coordination signatures — timing, shared assets, copied wording — distinguishes orchestration from genuine agreement; checking account authenticity discounts the amplifier network; and comparing online intensity to a verifiable offline footprint exposes the mismatch that fabrication produces. Reporting suspected networks to the platform and consciously declining to update your beliefs on the strength of manufactured consensus closes the loop the operation is built to exploit. This entry catalogs detection indicators only, not any means of building or operating such a network.
