The Mental Health Continuum
Keyes's two-dimensional model establishing that the absence of mental illness and the presence of mental health are independent axes — the diagnostic architecture the AI transition most urgently needs.

Keyes's epidemiological research, conducted across decades and populations, demonstrated this assumption to be empirically false. Mental illness and mental health are related but independent dimensions. A person can be not-ill and not-well simultaneously — functional, adequate, meeting obligations, and empty. The continuum model makes this territory visible, classifying individuals as flourishing, moderately mentally healthy, or languishing based on validated assessment across emotional, psychological, and social well-being.
