Scientific Basis

Why Not MBTI?

These archetypes are grounded in Attachment Theory (Bowlby, 1969; Ainsworth, 1978) and the Big Five personality model (Costa & McCrae, 1992) — the two most empirically validated frameworks in relationship psychology. Unlike MBTI, which has poor test-retest reliability (Pittenger, 1993), these frameworks have been replicated across 50+ cultures and have strong predictive validity for relationship outcomes.
