The HBDI Profile

A Tool For Training and Orientation

Ned Herrmann's Cerebral Preferences Approach

Based on neurobiologist Roger Sperry and Paul McLean's research on brain function, the American researcher Ned Herrmann developed the HBDI questionnaire (Herrmann Brain Dominance Instrument) which, after treatment, produces the "Profile of Brain Preferences" of a client. 


It becomes possible to understand how our professional choices and the way we work, learn, manage and communicate are influenced by our brain preferences.

For the Herrmann tool, there are no good or bad answers.


It is neither a psychometric test nor an IQ test.


The HBDI profile is a grid that functions as a simplified map of the human mind to identify learning processes specific to each individual and to see, depending on the situation, the parts of the brain that intervene.

The Individual Profile

Your HBDI profile illustrates how you learn, communicate and make decisions. We operate in interaction with the world, and each situation requires different styles of thinking. Understanding your personal styles allows you to optimize your words, your efforts and your actions in all situations of your personal and professional life.


Have you ever wondered:

  • Why is it easier to communicate with some than with others?

  • Why are some school subjects easier than others?

  • Why are some professional activities more satisfying than others?


Your profile is a representation of the four styles of thinking you use in your daily life. Everyone can access these four main styles but for the vast majority of people, two of the four are dominant.


This dominance is the answer to these questions because your abilities, your choices and your strengths as well as your weaknesses are influenced by your brain preferences.

The Team Profile

The tool is an ideal base for teamwork. It highlights the strengths of the group, its potential and explores the best avenues for collaboration and communication.


It clearly indicates the points on which an improvement is desirable and makes it possible to manage the team and the individuals who compose it according to their individual styles.


It also allows each member of the team to become aware of differences, similarities, challenges and opportunities.


Finally, it can allow a manager to identify the management styles to use and the tools to implement to motivate each member of his team.
