Herrmann International is the creator and originator of the HBDI® - Herrmann Brain Dominance Instrument®, and of Whole Brain® Technology.

HBDI Profile®

The connected distribution of thinking preferences

The HBDI® is capable of measuring the degree

of preference of the four individual thinking structures (quadrants) and each of the four paired structures (modes).

This thinking assessment is accomplished

through a 120-question survey instrument,

the responses to which assess the strength of

the four different thinking quadrants and

compares each to one another. This results in

a four-quadrant profile, which displays the

degree of preference for each of the four


This ability to profile thinking styles is a major

application of Whole Brain® Technology. As

a tool, the HBDI® is the validated, worldwide

standard for accomplishing this assessment.

Once an individual or group has their HBDI®

profile, they are better able to successfully

apply not only their understanding of their

thinking style, but also their preferred learning,

communicating, and problem solving

styles, to name a few. Experience over the last

25 years has shown that individual and group

applications of the HBDI® and the Whole

Brain® Technology are almost without limit.

Dominance, such as handedness, can occur between two parts of a physically living whole. Dominance is perfectly normal and natural. It is part of the human condition, and all human beings experience its consequences everyday. The human body is made up largely of paired structures, most of which are not perfectly matched.

Of major importance are the paired structures that exist in the brain. These are comprised of the two cerebral hemispheres and the two halves of the limbic system, both of which are connected together by powerful links that allow the four of them to function on a coordinated basis. Just as is the case with our hands, feet, and eyes, these paired brain structures are asymmetrical. They are different physically and chemically as a result of being specialized to think in different ways and to do different things.

In the case of hands, feet and eyes, these dominance        differences are quite obvious. For example, we use our dominant hand more frequently than our non-dominant hand and, therefore, it becomes stronger and more capable. In the case of the brain, our preference to think in particular ways results in more frequent use of that particular brain part (one hemisphere or one limbic half ) with the resulting development of greater competency for that set of mental activities that are located in those specialized parts. Just as our less developed non-dominant hand assists our stronger, more skillful dominant hand, the less developed brain structures collaborate with the more preferred (and therefore dominant) thought processes of our brain in order to more fully apply our best mental ability to everyday tasks and events. It is natural for our brain to form a coalition of the specialized structures in order to deal with complex situations.  At birth, the brain is without developed preferences, and, is therefore, essentially whole. As the brain matures, it acquires preference as a result of the individual’s life experiences. The developing brain is, therefore, an evolving coalition of many different preferences.

Whole Brain® technology provides a basis for measuring these different preferences by determining the degree of dominance that has developed among the four thinking structures of the brain. These parts consist of the two cerebral hemispheres and the two limbic halves.  All four of which are massively interconnected. Taken together, these represent a Whole Brain® divided into four equal quadrants, designated as A, B, C, and D.
