The model of hierarchical complexity (MHC), developed by Commons, is a way of measuring the complexity of a behavior. The MHC uses mathematical principles to quantify behavioral characteristics, assigning individuals to stages based on properly completed tasks. It can be used cross-culturally, across different species, and even for computers, and allows us to treat behavior accurately and in all-or-nothing terms. The MHC has many useful applications, such as in therapy, interventions, the development of organizations, etc.
