An Investigation of the Relationship between MBTI Personality Types and Decision-Making Competence - Issue 10 - Abstract, Introduction, and Key Findings

Sep 17, 2026

Paper examines whether Myers-Briggs Type Indicator (MBTI) personality types relate to decision-making competence. The study analyzes responses from 121 high school (age 15-16) and university students (age 19-25) who completed an MBTI test and the Adult Decision-Making Competence instrument. Correlation and variance analyses test links between eight MBTI personality dimensions and six decision-making competencies, including derived variables based on opposite dimensions. Results show only limited significant relationships and no differences across four basic MBTI types, indicating MBTI types do not determine decision-making styles and good outcomes can arise through multiple paths.

Relationships between MBTI personality types and decision-making competencies were the object of interest in present study. 121 high school (age 15-16) and university students (age 19-25) completed MBTI test and Adult Decision-Making Competence to assess their personality and decision-making competence. Correlation analysis and analysis of variance were used to investigate the relationship between personality and decision-making competence. Correlation analysis revealed that only five of 48 relationships between eight personality dimensions on the one hand and six decision-making competencies on the other hand were significant. Similar results were found by the relationship between decision-making competencies and new variables created as the differences between two opposite dimensions. No differences in decision-making competencies were significant by the comparison of four basic MBTI types. MBTI personality types do not associate with decision-making styles. This result points out that good decision-making outcomes are not exclusive for certain personalities and can be achieved by various ways.

While Myers-Briggs Type Indicator (MBTI) is used mainly to assess personality structure, it can be also viewed as a measure of different ways of processing information. The main aim of the present paper is to investigate a relationship between cognitive functions on one hand and the ability to make proper decision (decision-making competencies) on the other hand. While it is not possible to prioritize one of the cognitive functions, their relationships to decision-making outcomes can aim the attention to certain functions with higher expected role in We are not looking on the results of these processes now, but it seems appropriate to expect better decision-making outcomes in people with higher level of decisionmaking skills. 1.1. Decision-making competence While the descriptive approach in decision-making just describes process and outcomes of decisionmaking, normative approach tries to set rules for proper decision-making and to asses

FAQs

What was the main research question of the study?

The paper investigates the relationship between MBTI personality types and decision-making competence (decision-making competencies), focusing on how cognitive functions and decision-making skills may connect.

How was decision-making competence assessed?

Participants completed the Adult Decision-Making Competence (A-DMC) instrument, which evaluates four core decision-making skills through six subscales and can be judged by accuracy and consistency.

What did the results show about MBTI and decision-making styles?

Only a small number of relationships between MBTI dimensions and decision-making competencies were significant, and comparisons of four basic MBTI types showed no meaningful differences, indicating that MBTI personality types do not associate with decision-making styles.
