The difference between a neurological and psychological analysis

Psychological and neurological analyses both aim at identifying the way a person functions (their decision-making process, self-organization, etc.). While both methods might seem nearly the same, the process contains strong differences.

What is a psychological analysis?

  1. A person is presented with a battery of different situations where several attitudes and opinions are possible
  2. The person is asked to choose how they would have acted and what their opinion is
  3. Lastly, the functioning of the person is defined based on their declared opinion

The limit of this principle lies in the long-term validity of the generated profiles.

In fact, the opinion of a person can evolve on certain subjects and would lead to different answers at 2 different times. Similarly, a questionnaire can only present a limited number of situations and is therefore not exhaustive.

To overcome these limitations, some questionnaires try to present as many situations as possible (which lengthens it even more) and the same situation is presented in several different ways and several times in order to ensure the objectivity of the person responding.

What is a neurological analysis?

A neurological analysis aims at defining the functioning of the person that would apply in any situation now and over time, based on the functioning of their brain.

To do this, questionnaires are using stimuli words: each area of the brain is responsible for both a person’s strengths and our limits. The terms used in the questions provoke different reactions in each brain area, leading to specific answers that will allow to understant the global functioning of the brain.

  1. A list of questions containing stimulus words is presented to a person
  2. The person reacts to each sentence according to the stimuli they receive through each set of words
  3. The recorded answers make it possible to define the most active brain zones and deduce the functioning of the person

This method is so deep that some questions are very clear to some (because the person frequently uses the targeted area of the brain) and very unclear to others (because the targeted area is used rarely).

The neurological analysis principle was validated in a laboratory by Dario Nardi Phd, researcher at UCLA (University of California, Los Angeles). He got awarded for his work that inspired the Unfair model (learn more).

Why use neurological analysis?

This system allows for faster analysis. Indeed, as we do not need to analyze a large number of situations but only the 18 areas of the brain, the number of questions to establish a profile is lower.

The neurological analysis also makes it possible to have higher reliability for the profile produced and for it to stay accurate over time - since the analysis isn’t based on specific situations, but directly on the functioning of the brain (which evolves, but doesn’t change over decades). Thus, it is not necessary to renew the analysis regularly.
