For hundreds and hundreds of years scientists have been looking into the fascinating world of the brain and its processes.Why do we think like we do?Why do we behave and communicate the way we do?
What explanations exist for the differences in thinking and behaviour within a family, between siblings, even twins?
We debate nature versus nurture, IQ and memory. We discuss creativity and its relevancy in an ever-changing world.

At the Kobus Neethling Institute (KNI), years of research by internationally acclaimed South African, Dr Kobus Neethling, has culminated in the development of the NBI system of thinking preference assessments.
These assessments provide critical insights into an individual's preference towards left-brain thinking, right-brain thinking and the various combinations there of.

By no means does the NBI system imply that a person only thinks in only one part or with only one part of his/her brain - that is not possible! We always use all of our brain to think. (In fact, once you understand your thinking preferences, the ideal is to develop whole-brain thinking.)
What the NBI system does evaluate, is the natural preferences or dominances we have with regards to thinking.

Let’s simplify this - if you are right handed, you use your right hand more often than your left hand when doing tasks. That does not mean that you do not have a left hand, that you do not need a left hand nor that you never use your left hand. Not at all. It simply means that there is a comfort in using your right hand, a natural “go to” when doing things.
NBI assessments allow us to evaluate you thinking “go to” - and this is essential!

For example, if you are a visual, big picture futurist and you choose a job that requires you to keep record of and count stock day after day, you will wither.
If a child with an visual, big picture furture-minded thinking preference is made to sit at a desk and bullet point his notes to learn history, that child will not memorise the information optimally, as it is to aligned with his/her natural preference, and this in turn will influence the child's marks (and his/her self-esteem and self beliefs) directly.

We simply must make the effort to understand these preference in order to fit into our individual and unique roles in life.
Parents must endeavour to find out this informations and help their children apply it to studying, to subject choices, to career choices.
Employers must know this information to correctly choose an employee for a specific position.
Teachers need to know and understand brain profiles, to teach in such a manner that all the children in their class can hear and understand the subject matter.
This list goes on and on.

Career Guidance

NBI Brain profiles provide an objective and in depth model of thinking preferences that form the basis of making career choices. Get access to your Brain profile, Job comparison reports and discuss your future vision, dreams and passions with a qualified NBI practitioner as guide.

NBI profiles are questionnaires done online.
Individuals have the option of completing their profile at home in their own time or can complete the profile at TFSA offices.
The NBI Brain Profile report is a 5 to 8 page report containing descriptions and explanation of the person's unique profile. It describes each quadrants (and dimension if the report was done for an adult/senior student) in detail.

It also contains a circle diagram/graph as an visual presentation of the report results.


Since our thinking influences how we behave, communicate, take in information, study, which careers would be appropriate and the like, the uses of NBI Brain profiles are vast!

NBI profiles aim to help:
  • you understand your unique thinking preferences, communication style etc.
  • you better understand those you relate to on a daily basis
  • parents understand and resolve conflict with their children 
  • students with their study styles and subject choices
  • students make informed career choices
  • resolve conflicts in personal and professional life
  • make the best possible choice when wanting to redirect to a new career
  • improve the level of creativity and leadership in business
  • select the best-suited employees for new positions
  • develop effective teams
  • retain valuable employees
  • develop the whole-brain mental edge in your sport
The NBI profiles can add great value the workplace.

Each postiontion in the workplace requires a specific set of thinking preferences and skills.
When an employer is wanting to employ a candidate for a specific position, it is critical to understand the candidate's thinking preferences and compare it to the thinking required by the specific position before making a final decision.

The NBI institute has various job profiles on hand to which employers can compare their candidates profile to, OR the employer can choose to set up their own Job Profile for the position, setting up a unique profile, specific to their business, to which the candidate's brain profile report can be compared.
