As per the Big Five/FFM or the HEXACO model, Openness/Intellect appears to be an important personality dimension on which humans differ from each other. People high on this dimension are variously described as creative, imaginative, intellectual etc. We will be only focusing on this trait of the big five/HEXACO/FFM for the purpose of this post.

MBTI is based on Jung’s theory: People may be Extroverted or Introverted, based on whether they find stimulation in the outer world preferable or find the inner world more a focus of their attention; and are low reactive/ high reactive respectively. They can also be predominantly focused on processing information and acting and deciding consistently (and thus using the Judging function) or on taking in information and acting flexibly and keeping options open (and thus using the Perceiving function). Within the judging function, they may rely more on logical analysis etc (the Thinking function) or go more by case-by-case basis (The Feeling function). Within the perceiving function, they may restrict themselves to facts and givens (the Sensing function) or  go beyond the givens and add meanings and interpretations (the iNtuition function). Depending on your propensities/ reliance on these four functions you would be categorized as INFP or ESTJ etc.

Some of the MBTI dimensions have been mapped onto the Big five/FFM/HEXACO.  The mapping of introversion-extroversion to eXtraverted trait of FFM/HEXACO is a given and self-evident, There could also be made a strong case for Judgement-Perception dimension to be mapped onto the Conscientiousness trait of the big five/FFM/HEXACO. However, there is no ready correspondence to Openness/Intellect trait and any of the MBTI dimensions/functions.

For the remaining analysis, I will like readers to refer to this article [pdf] that talks about AB5C model and lists five factors of personality:

For the NEO, the column defined by high loadings from the Extraversion facets is labeled Factor I, for the Agreeableness facets, Factor II, for the Conscientiousness facets, Factor III, the Neuroticism facets, Factor IV, and the Openness to Experience facets, Factor V.
Its important to note that Openness to Experience, like other NEO factors, is made of six facets. These are Openness to Aesthetics, Openness to Feelings, Openness to Ideas, Openness to Actions, Openness to Values and Openness to Fantasy.  The paper goes on to show that different facets of Openness to Experience can be construed as a combination of core Openness to experience factor V as primary factor and either low/ high  Conscientiousness (factor III) or low/high eXtraversion (factor I) as a  secondary factor.

For eg. Openness + high Conscientiousness = factor V + high factor III = terms like analytical, intellectual, intelligent, knowledgeable. This sub-factor of openness may be related to intelligence and may be called Intellectual. Its my contention that NEO facets like Openness to Ideas belong here. This is also closely related to the Thinking function of MBTI and is cognitive in nature (as per the fundamental four model).

Similarly, Openness + low eXtraversion = factor V + low factor I = terms like artistic, creative and imaginative. This sub-factor of openness may be related to creativity and may be called Instinctual. NEO facets like Openness to Feelings and Openness to Aesthetics belong here. This is also closely related to the Feeling function of MBTI and is affective in nature (as per the fundamental four model).

Similarly, Openness + low Conscientiousness = factor V + low factor III = terms like changeable, unorthodox. This sub-factor of openness may be related to fantasy-proneness and may be called Imagination. NEO facets like Openness to Fantasy belong here. This is also closely related to the iNtuition function of MBTI and is motivational/dynamic in nature (as per the fundamental four model).

Similarly, Openness + high eXtraversion = factor V + high I = terms like experimenting, original, prefer variety. This sub-factor of openness may be related to reality-orientation and may be called Innovation. NEO facets like Openness to Actions and Openness to Values belong here. This is also closely related to the Sensing function of MBTI and is behavioral in nature (as per the fundamental four model).

Talking in more abstract terms, the sub-factor of openness called Intellectual may be concerned with Truth, the sub-factor Instinctual with Beauty; Imagination with Possibility/probability while Innovation with Utility. While the former two are idealistic in nature (and being related to Thinking and Feeling, belonging to Judgement), the latter two are more pragmatic in nature ( being related to iNtuition and Sensing, belonging to perception).

To me this linkage of MBTI with openness to experience facets looks a promising future direction and makes immense sense; In a later post I will talk more about MBTI and FFM in more general terms.

PS: this post followed as a result of reading a recent paper [pdf] by Scott Barry Kaufman et al on structure of intuitive abilities and its relationship to Openness to Experience/ intelligence.
