The MBTI (Myers–Briggs Type Indicator) personality test is a widely used psychological measurement tool. It aims to assess an individual's personality type. Based on the psychological theories of Carl Jung, the test categorizes individuals into 16 different personality types. By answering a series of questions, the test helps people understand their preferences in four dimensions: Extraversion (E) or Introversion (I), Sensing (S) or Intuition (N), Thinking (T) or Feeling (F), and Judging (J) or Perceiving (P).
