For the last 150 years, the science of psychology has dedicated itself to identifying and describing the various manifestations of human cognition, behaviour, and affect. While significant progress has been made in this realm, less progress has been made in identifying the common characteristics that give rise to these elements.

This failure to identify the common characteristics that are responsible for maladaptive cognition, behaviour, and affect has created a situation where most treatment protocols have low efficacy rates and even with those that are more effective, we can do little more than hypothesise as to why they’re effective.

The Unified Theory of Human Psychology is an attempt to identify the common bonds between the various psychological schools of thought and produce a complete understanding of the foundation elements that drive human cognition, behaviour, and affect.
