Herrmann Brain Dominance Instrument (HBDI)


As a leader, manager, consultant or person responsible for solving problems, making improvements or creating ideas, you can lead the way. Start by tapping into the unique way you like to think. Enable both yourself and your team to think together effectively and contribute to innovation. By using new approaches you’ll make a difference that matters.

You probably already know something about left brain and right brain. Go beyond that to measure and identify four distinct thinking styles and see your profile in each one. When you know how you prefer to think, you can build upon your strengths and even advance in your less preferred categories. Your individual performance perks up and your ability to work well with others soars. You and your team can reach new heights, get more done with less hassle, save time and money, and improve results.

You accomplish this with an assessment tool called the Herrmann Brain Dominance Instrument. Consisting of 120 questions, the HBDI can be tried over the Internet or on paper.

Your Whole Team can benefit too.

Teams and groups as well as individuals can benefit by understanding how they think collectively. A team profile is an excellent tool for expanding your awareness, appreciating the strengths of others and developing new products and services that meet all the needs of your customers.

What is Whole Brain Thinking?

You have no doubt heard about left brain right brain, but whole brain thinking expands on that idea. Brain research shows four structures and HBDI assessments measure four distinct styles of thinking.

Current research shows that the human brain is highly specialized. The research from Herrmann International shows that there are an equal number of people in all four basic groups. The four quadrant whole brain model allows for more sophisticated combinations that measure both intellectual and emotional preferences which influence thinking styles and learning styles.

The HBDI draws on brain physiology research of Nobel prize-winning scientists like Roger Sperry and Michael Gazzaniga. It was developed by the late Ned Herrmann at General Electric using advanced brain scanning technology. The HBDI model has been validated by more than 60 doctoral theses and scientific study, and by the satisfaction of more than 300,000 participants.

Is the HBDI Valid?

The brain dominance concept has been strongly validated in a number of different ways:

  • Through the research and experimentation of leaders in the field including Roger Sperry, Robert Ornstein, Henry Mintzberg, and Michael Gazzaniga.
  • By the hundreds of EEG experiments carried out personally by Ned Herrmann.
  • By the public demonstrations conducted by Ned Herrmann over the past 15 years.
  • By specific validation studies carried out by C. Victor Bunderson and James Olsen of Wicat and later by C. Victor Bunderson and Kevin Ho, and in parallel with those studies by validation experiments carried out by Schadty and Potvin at the University of Texas.
  • More than 60 doctoral dissertations based on both the HBDI and the whole brain concept.
  • Thousands of anecdotal validations coming from people who have acknowledged verbally or in writing their strong personal acceptance of the HBDI profile as descriptive of themselves and their extremely positive feedback about the understanding both the profile and the concept has provided in terms of understanding others in their personal and work lives.
