A phrase used to summarize the first six major levels of values development according to Clare Graves and Spiral Dynamics: Survival Sense, Kin Spirits, Power Gods, Truth Force, Strive Drive, and Human Bond. First-Tier stages are characterized by a belief that “my values are the only correct values.” This lies in contrast to Second-Tier levels of development, wherein individuals recognize the importance of all value systems. Integral Theory uses First Tier to refer to the first six degrees or levels of developmental altitude (Infrared, Magenta, Red, Amber, Orange, and Green).
