How effective is the MBTI?


The MBTI (Myers-Briggs Type Indicator) is defended by Andrew Bustamante for its utility in understanding core personality traits, particularly in demanding or resource-constrained environments. He highlights its use in major spy agencies globally and argues that core personality traits, which are revealed in dire conditions, do not change over time. He also points out that while there are criticisms of the MBTI, such as its fixed categorization of personality traits, its operational usefulness, especially when proper assessments are used, is highly valued in both corporate and espionage contexts 1 2.
