School entities are the named theoretical movements and paradigms this atlas documents, psychoanalysis, behaviorism, cognitivism, humanism and their successors, each carrying a SubLabel matching one of five founding branches (Clinical, Behavioral, Cognitive, Developmental, Community). A school is a broader, often historical intellectual movement that many psychologists and theories belong to or draw from, distinct from a branch, which is a subfield of practice, and distinct from a single theory, which is one specific explanatory claim a school's adherents may hold. This band is where a reader browses psychology by its rival paradigms and their historical succession, the nature versus nurture divide, the cognitive revolution's break from strict behaviorism, and other genuine intellectual conflicts the field itself has not resolved, named as debated rather than settled.
