Maslow’s (1943) hierarchy of needs remains one of psychology’s most influential theories of motivation. Yet abundant phenomena contradict its fixed-priority assumption: martyrs sacrifice survival for beliefs, parents die for children, artists embrace poverty for creation.We propose a fundamental replacement grounded in reinforcement learning. First, we redefine needs as mechanistically equal approach/avoidance tendencies that differ in genetic baselines but are equivalent in plasticity—any need can exceed any other through sufficient reinforcement. Second, we identify three distinct reinforcement mechanisms reshaping need priorities: (1) primary reinforcement through direct biological rewards, (2) associative reinforcement via learned pairings, and (3) symbolic reinforcement from cultural narratives and self-concepts.These mechanisms operate sequentially across development and explain cross-cultural value diversity. Third, we demonstrate how this framework resolves Maslow’s counterexamples while generating falsifiable predictions, including quantitative criteria for falsification.We integrate neuroscience evidence showing shared reward circuits, developmental psychology revealing ontogenetic emergence patterns, evolutionary psychology explaining genetic baselines as adaptations, and behavioral economics illuminating subjective value computation.Practical applications include education cultivating intrinsic learning needs through strategic pairing, clinical psychology treating addiction through reinforcement decoupling, and AI ethics requiring genuine experientially-reshaped needs for moral status. This paradigm shift replaces static hierarchy with dynamic mechanisms, preserving phenomenological insights while providing testable neurobiologically-grounded explanations.
