TY - JOUR AB - Purpose– Pluralities of personality schemas reside across different Maruyama universes suggesting incommensurability and isolation. Schemas may migrate across Maruyama universes given appropriate means. As illustration, the Myers Briggs Type Indicator (MBTI) schema for personality temperament is migrated into a sociocognitive schema through the intermediary of knowledge cybernetics (KC). MBTI is a type approach that operates with polar opposites; however, conceptually there is no reason for it not to be associated with a trait space. Supposing that MBTI has traits at some horizon of meaning, then since traits are responsible for the creation of enduring states, sociocognitive explanations should be able to explain the stable states consistent with a variation of the McCrae and Costa proposition. As a result this paper aims to formulate for the first time a link between the MBTI type schema, a trait space, and a capacity for sociocultural descriptions.Design/methodology/approach– The paper uses the meta‐framework of KC, part of the relevantial universe identified by Maruyama, to formulate a representation of MBTI. This also appears to be the first serious use of the Maruyama universe concept, and the first time that MBTI has been explored from a relevantial perspective. A consequence is the possible development of a more sophisticated trait theory that is capable of providing more complex information about personality.Findings– The findings indicate that a more complex form of type theory is possible than has been provided by MBTI.Research limitations/implications– This paper is limited to the investigation of MBTI. However, it offers a generic approach that can be applied to other solitary theories like MBTI. It also postulates a trait basis for the MBTI type approach.Practical implications– The paper leads to the possibility of improved explanatory power for a type theory than is currently possible.Originality/value– The paper adopts for the first time a relevantial meta‐framework approach to explore a development of MBTI. It has value to those researchers who may wish to explore the potential of more complex forms of type personality theory than are currently available.
