Relevance Only Exists for Agents That Care About Themselves

Recursive Relevance realization — the capacity to iteratively zero in on what matters from a combinatorially explosive space of possibilities — is proposed as the core mechanism underlying intelligence and consciousness. Crucially, relevance is not an observer-independent property of the environment. It is relational: it exists only for an agent with needs, goals, and stakes. A paramecium finds a glucose gradient relevant; a stone finds nothing relevant. This asymmetry points to a deep structural dependency: Relevance realization requires autopoietic agency, and autopoietic agency requires Relevance realization. The two co-define and co-determine each other.

The implication is that all relevance is ultimately self-relevance — not relevance to a folk-psychological "self" but relevance to a self-sustaining, self-making system. An organism that must maintain its own organization is the minimal unit for which anything can matter. This is reflected in the very language of cognition: "matter" implies weight-for-me, "import" means bringing into one's world, "paying" attention treats cognitive resources as finite and personally owned. These are not mere metaphors — they reveal the autopoietic ground of cognitive life.

Convergent evidence from cognitive psychology supports this architecture. Self-referential processing enhances memory encoding, perceptual binding, and attentional capture. The self-relevance effect is among the most robust findings in the field. This framework therefore provides a theoretical bridge between the science of Relevance realization — central to theories of intelligence and consciousness — and the psychology of the self. Agency, relevance, and selfhood are not three separate research programs but three faces of a single underlying structure.
