Gregg Henriques' Tree of Knowledge System is an ambitious attempt to provide a systems-wide framework for the study of the discipline of psychology generally. Although Henriques' system deals with psychology-in-general, it is both relevant to personality psychology, and partly compatible with the Systems Framework. Both systems, for example, employ a molecular-molar dimension in viewing personality -- or psychology.
Henriques' systems adds in evolutionary and cultural mechanisms for how human psychology develops and evolves. These include the concept of the Justification Hypothesis and the Behavioral Investment Theory.
