Abstract: Human society is undergoing a historic turn toward “deep agentification”: the relationships between people, between people and businesses, and between people and information are being systematically mediated by artificial intelligence (AI), and the scarcity logic of intellectual labor is collapsing as a result. This paper proposes the fifth paradigm of social research, the Agentic Intelligence Paradigm, and constructs it at three levels: ontology, methodology and communication studies. At the ontological level, the paper takes the Compressed Collective Representation Snapshot (CCRS) as the conceptual cornerstone of a new type of empirical material. It argues that a CCRS is, in essence, a second lossy compression of a pseudo-environment that has already been processed by the media, that is, a “compressed pseudo-environment”, and that the loss incurred by this compression is itself an object of measurement. At the methodological level, the paper takes the permutation of the three roles of researcher, instrument and object as a generative rule, from which five operational modes are derived: inquiry, role-playing, swarm, adversarial and reverse. It replaces “substitution validity” with “representational validity” as the reference axis of validity, and builds six elements of measurement design, a system of five validity indicators, a seven-source Total Representation Error (TRE) framework that includes “recursive echo error”, and a multi-round question-answering protocol. Using real data collected on the AIciting.com platform, it conducts preliminary tests of five propositions: statistical focusing, mirror refreshing, source feeding, parallel agendas and conditional branching. At the level of communication studies, the paper puts forward two propositions, “cognitive folding” and “generative agenda-setting”. It argues that the upstream of agenda-setting, namely “who is feeding the collective consciousness”, now becomes visible as an auditable list of sources, and that communication governance must shift from content governance to model governance centered on representation auditing. The Agentic Intelligence Paradigm does not replace the four classic approaches of survey, experiment, field research and documentary research; instead, it forms a triangulation with them. It moves social research from “analyzing data” to “conversing with knowledge hybrids and auditing such conversations”, and may enable communication studies to transform from a summarizer of experience into an auditor of cognitive infrastructure.
