With our NERIS^® model, we’ve combined the best of both worlds. We use the acronym format introduced by Myers-Briggs for its simplicity and convenience, with an extra letter to accommodate five rather than four scales. However, unlike Myers-Briggs or other theories based on the Jungian model, we have not incorporated Jungian concepts such as cognitive functions, or their prioritization. Jungian concepts are very difficult to measure and validate scientifically, so we’ve instead chosen to rework and rebalance the dimensions of personality called the Big Five personality traits, a model that dominates modern psychological and social research.

Our personality types are based on five independent spectrums, with all letters in the type code (e.g. INFJ-A) referring to one of the two sides of the corresponding spectrum. You can see where you fall on each scale by completing our free personality assessment, NERIS Type Explorer^®. This approach has allowed us to achieve high test accuracy while also retaining the ability to define and describe distinct personality types.
