What is NBI®?

NBI® is a validated method that helps us to understand our brain profiles. The different combinations of clusters of thinking processes make us unique individuals. We all know people who have a preference for details while others have a preference for the big picture. Some have a preference for step-by-step processes while others have a preference for an unstructured way of working. Some are results-driven while others are people-driven. These are just a few examples of different brain preferences.


Some of these preferences are obvious to us and others around us but that is just the tip of the iceberg. The full impact of our brain preferences on what drives our behavior can be realized by uncovering the actual iceberg and NBI® offers the world’s largest battery of tools that do exactly that.


This method which has been applied successfully internationally for more than 30 years was introduced to the Netherlands in 2009 as Breinvoorkeuren NBI® by Koen Zonneveld. Breinvoorkeuren is Dutch for brain preferences. The instruments are in the form of online questionnaires that are available in the languages of the countries where they are used.


NBI@ is not a new fad. These instruments are based on tried and tested principles that were first discovered in the 60s. They were developed by Dr. Neethling as part of his post-doctoral studies in Georgia University, USA, after conducting a scientific study that involved thousands of adults and children from a number of countries.

An NBI® profile is neither good nor bad. It is a descriptive, objective analysis of the individual’s thinking processes, with no profile being better or worse than another. It gives an indication of how you act towards others, do business, communicate, learn, teach, approach problems, form relationships, etc.


“Knowing your personal brain profile is the key to success and happiness in your career, relationships and personal well-being”. Dr. Kobus Neethling – Founder of Neethling Brain Instruments®.

Most people are familiar with the fact that certain areas of the brain are responsible for various functions. E.g. The left hemisphere  of the brain controls the right side of the body, the right hemisphere of the brain controls the left side of the body and Broca’s area is responsibe for language production. We also know that different functions are not necessarily physically located in areas of the brain such as the left or the right side.


However, ‘Left brain, Right brain’ has become a useful metaphor. Thus the L1. L2, R1, R2 model that (NBI®) uses should not be mistaken for a schematic representation of the brain. These quadrants represent clusters of brain functions that go together.


A major strength of NBI® is that it goes beyond the 4 quadrants. There are significant differences in the two dimensions within each quadrant, so NBI® looks into the 8 dimensions as represented here. A good example is the R2 quadrant. A person with high preferences in the dimension Socialiser and one with high preferences in the dimension Empathiser are both referred to as ‘people person’ and they are both relationship driven. That is why both dimensions are in the same quadrant.


However, there is a significant difference between them. The one with high preferences in the dimension Socialiser asks ‘with whom?’ and the one with high preferences in the dimension Empathiser asks the question ‘For whom?’ If you only look at 4 quadrants you can only rely on guesswork. NBI® eliminates that guesswork.

NBI® does not label you or put you in boxes - one of the quadrants or dimensions. You are not ‘an L2’ or ‘an Organiser’. You are a unique human being. Your profile just indicates in which dimensions you have dominant preferences. No one has preferences in only one quadrant or dimension and zero preferences in another. The world is not made up of 8 types of people. The world is made up of 7 billion unique individuals who share some common preferences in unique combinations. With the knowledge gained from NBI®, you have the ability to adapt your thinking and reactions to be more adaptive to your environment.
