Scientists know that there are four main centres in the brain that process information, that
each centre processes information in different ways and that each will take a greater or lesser
responsibility for processing information in different people.

We refer to the relative strengths of each of these processing centres as a person's “Brain Dominance”. In other words, just as a person might have a preference for catching a ball with one hand rather than the other, they will also have preferences regarding the way they think.

The tool we use for analysing a person’s brain dominance is called the Herrmann Brain Dominance Instrument® (HBDI). Despite its rather ominous sounding name, it consists of a simple questionnaire that measures a person’s preferences, not their abilities. There are therefore no right or wrong answers, only differences.
