A Hypothetical Reconstruction of MBTI Functional Architecture: The Case of a Mistyped INTJ

This project presents a personal hypothesis proposing a structural redefinition of the MBTI framework. Based on self-observation and a reflective analysis of a misclassification as INTJ, the author argues for a model in which the eight MBTI cognitive functions are mapped onto eight independent neural modules, potentially expressed along four bipolar axes analogous to dominant–recessive gene dynamics. The hypothesis bridges MBTI theory with insights from neuroscience, psychometrics, and gene expression, aiming to quantify each function as a continuous variable. It also explores the distinction between internalized language structures and actual cognitive dominance, emphasizing the need to decouple observed linguistic patterns from underlying cognitive mechanisms. This work is not an academic publication but a theoretical prototype generated through personal modeling. It is shared for open discussion, cross-disciplinary curiosity, and possible future validation. All insights are rooted in system-level thinking and structured self-reflection. Version Note: This version (V2) revises and expands the original “MBTI Functional Opposition and Expression Hypothesis”, providing a more coherent integration of cognitive function pairs, neurogenetic regulation models, and quantitative function matrices. Key enhancements include structural clarification, gene-pathway analogies, and the proposal of a closed-loop modeling approach from personality to cognitive science.
