Input Restoration Therapy

Input Restoration Therapy proposes a unified ecological framework for understanding human psychological collapse and recovery. Across biological systems, organisms reduce behavior, complexity, and engagement when required environmental inputs are missing, and re-expand when those inputs are restored. Drawing on evidence from ecology, sensory biology, development, aging, and clinical practice, the paper formalizes a universal operator: identify the missing input, restore it, and allow the system to reorganize itself. This framework reframes withdrawal, lethargy, apathy, and loss of function not as internal dysfunctions but as predictable responses to input deprivation. By shifting the focus from correcting the individual to repairing the environment, Input Restoration Therapy offers a coherent, cross-species model of development, recovery, and human flourishing.
