Personality Interests

Research into popular personality instruments

The world of personality tests is vast and varied, so we prefer to focus on a few established models of personality centered around Jungian theory.

Our researchers collect and analyze the world's personality data. We consider the most established personality test models such as the Big Five (NEO P-IR), Enneagram, Jungian (16-types), and DISC, but we specifically focus on the Enneagram test and 16-type personality test. The most popular version of the 16-type model is the MBTI®.

Our psychologists expand the work of others and we develop our own personality models, such as the extended subtype model.

We publish surveys and collect respondent data from around the world. We then use statistical tools such as factor analysis, multiple regression, and item response theory (IRT) to report our findings. To learn more about how we do this have a look at our science page.

An underlying principle of this model is three dichotomies of extraversion vs. introversion, sensing vs. intuition, and thinking vs. feeling described by Carl Jung in 1921. This was later developed by developed by Isabel Briggs Myers to include a fourth dichotomy of judging vs. perceiving.

The Enneagram is a model of personality represented visually by nine types around a circle. The geometry of the circle expresses how each type is related to another. Every person is one of the nine types, but it is possible to have traits of other types.
