The Whole Brain Model is a metaphor for how we think. Although originally developed using an actual testing of brain activity, the HBDI profile does not purport to represent the actual synaptic activity of the physical brain at any given moment. It represents a picture of your thinking preferences. Research shows that we all have access to our whole brain and are constantly activating many different areas simultaneously. Over the course of our lives we develop patterns of usage that ultimately result in our thinking style preferences. The HBDI profile is designed to provide a picture of that array of preferences, giving you a way to understand and describe your preferred ‘clusters’ of thinking and how those preferences impact your effectiveness and choices, as well as how they may differ from those you live and work with.
