Humanistic psychology has long maintained that genuine growth involves becoming more congruent, more authentic, and more capable of inhabiting experience without defensiveness or fragmentation — a concern exemplified in Rogers’ account of congruence, Maslow’s distinction between cognitive development and self-actualisation, May’s account of existential authenticity, and Bugental’s clinical emphasis on genuine presence. The increasing influence of constructivist and developmental frameworks within the broader field has, however, introduced an assumption that humanistic psychology has not adequately examined: that increasing psychological complexity implies increasing psychological wholeness. This paper argues that sophistication and integration represent partially independent dimensions of psychological organisation, and introduces the integration–sophistication distinction to articulate their relationship with theoretical precision. A two-dimensional framework is developed, identifying four configurations — fragmented simplicity, grounded simplicity, sophisticated adaptation, and mature integration — that illustrate how considerable complexity can coexist with persistent incongruence, and how profound coherence can emerge in its relative absence. The paper examines why sophistication is so frequently mistaken for integration, particularly within high-achievement, leadership, and contemplative contexts, and draws out implications for humanistic theory, constructivist psychology, and psychotherapeutic practice. The distinction is offered as a conceptual resource for enriching humanistic psychology’s own understanding of the relationship between authenticity and complexity, not as a new hierarchy of human functioning.
