Contemporary theories of consciousness have produced increasingly sophisticated accounts of neural activity, information integration, cognitive architecture, predictive processing, and adaptive behaviour. Yet a fundamental question remains: for whom are these processes present as experience? This paper introduces the For-Whom Constraint, a proposed criterion of explanatory adequacy for theories of consciousness. The For-Whom Constraint holds that a theory remains incomplete if it explains the mechanisms, functions, or structures associated with consciousness without accounting for the condition by virtue of which those processes are experienced or known. A theory may successfully explain how information is processed, represented, integrated, or globally broadcast, while leaving unanswered why such processes are present as experience at all. Unlike the Hard Problem of Consciousness, which identifies the explanatory gap between physical processes and subjective experience, the For-Whom Constraint is proposed as an evaluative criterion for assessing candidate theories. It does not presuppose a particular metaphysical account of consciousness. Rather, it asks whether a theory explains only the organization and functioning of a system or whether it also addresses the subject, standpoint, or condition under which experience becomes manifest. The paper examines how major approaches—including physicalist, information-theoretic, higher-order, predictive-processing, and panpsychist theories—respond to, circumvent, or leave unresolved this challenge. It argues that many influential theories provide powerful accounts of the correlates, structures, and functions associated with consciousness while remaining silent on the existence of an experiencer or knower. By distinguishing explanations of processing from explanations of experience, the For-Whom Constraint offers a framework for evaluating competing theories of consciousness. The paper concludes by exploring the implications of this criterion for future philosophical, scientific, and interdisciplinary investigations into consciousness, subjectivity, and the nature of knowing.
