See: List of Concepts
The Human Stack is derived from Edward Hall’s model of the Cultural Iceberg. The key concept behind the Human Stack is that while there are certain observable characteristics of people at the visible level which we refer to as “above the waterline” there are also characteristics and traits of people which are not immediately visible, which we refer to as “below the waterline”. Most important are the Values that individuals hold (See: Concept: Values), which guide their behaviour.
For the purposes of Community building, Value alignment among the individual members is the most important consideration (See Concept: Value Alignment).
