While we often think of type as just a single model-a single way of looking at human interactions-it is actually quite rich because the whole of "type" is a cluster of related compatible models: 16 whole types, functions in their attitudes, type development, temperament, interaction styles and so on. They are part of the "type family."
1) Compatible models:
The multiple models within type theory are not reducible to a single model. They are compatible but distinct and complementary without contradicting each other.
