An Investigation of the Relationship between MBTI Personality Types and Decision-Making Competence
Main Article Content
Abstract
Myers-Briggs Type Indicator (MBTI) belongs to the most widely used personality measures, but its associations with decision-making were rarely explicitly studied. 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.
