Authority in Human Design is a decision-making concept derived from the calculated BodyGraph. It is not a personality label and should not be inferred from birth date alone. The authority shown in a chart depends on defined centers and their hierarchy. Emotional authority emphasizes waiting for clarity across an emotional wave; sacral authority emphasizes an immediate bodily response; other authorities follow different structural rules. Use authority as a reflective experiment rather than a substitute for evidence, consent, professional advice, or responsibility. The chart should make the underlying centers and channels visible so the label can be checked.
