Psychologists have studied certain elements of wellness, and various aspects of fairness, but they have seldom studied the interaction between the two. As a result, it is not surprising that there is a paucity of educational, community, clinical and social interventions to promote wellness and fairness in concert. In this paper I present a framework of justice consisting of substantive and contextual types. Distributive and procedural justice constitute the two main types of justice. Interpersonal, organizational, cultural and communal justice are contextual types which embed within them the two substantive aspects of justice. I explore how these various kinds of justice impact human development across six facets of well-being: interpersonal, communal, occupational, physical, psychological and economic. I claim that for children and adults to achieve optimal human development, these facets of well-being must be supported by various types of justice.
