“The Human Design System shows how the four types actually make up a structured ‘genetic hierarchy’, which highlights the way different human beings are designed to interact with each other. In this hierarchy, we are all interdependent, just like the cells that make up our bodies. Below is a symbolic matrix of the way in which the four types interlock with each other. The two energy types, manifestors and generators form the creative foundation, with projectors at the top of the hierarchy being the natural guides, although they are also dependent on the two energy types below. In the centre are the reflectors. These people are designed to be the hub of their communities, playing a vital role in bringing a sense of justice and balance to the hierarchy as a whole.” -Richard Rudd, Opening Doors with Gene Keys
