• We all have the four basic needs (Stability, Proximity, Change, Distance), but to a more or less obvious extent.
  • Each person is characterized by a privileged area (called predominance) which determines their basic personality.
  • The predominance can vary: we move flexibly between the four poles, according to situation and context.
  • The model is not static, but dynamic; there may be changes over a lifetime.
  • The model is not evaluative; each personality possesses PROs and CONs.
