This comprehensive test evaluates all eight Jungian cognitive functions: Introverted Thinking (Ti), Extraverted Thinking (Te), Introverted Feeling (Fi), Extraverted Feeling (Fe), Introverted Sensing (Si), Extraverted Sensing (Se), Introverted Intuition (Ni), and Extraverted Intuition (Ne). With 58 questions, it provides a detailed cognitive function stack and derives your MBTI personality type.
Unlike simple MBTI type quizzes, this test measures each cognitive function independently using position-weighted scoring. The result includes your dominant and auxiliary functions, a visual radar chart of all eight functions, your four-letter MBTI type with match percentages, and a proprietary VMIC personality suffix that captures nuances beyond standard typology.
Carl Jung introduced the concept of cognitive functions in his 1921 work Psychological Types. These functions describe how people perceive information and make decisions. Each person has a natural preference for certain functions, which form their cognitive function stack. Understanding your function stack provides deeper insight than a simple four-letter type — it reveals how you think, not just what type you are.
Questions are grouped by cognitive function and scored using a weighted system where strongly agreeing with a function-specific statement earns maximum points for that function, while strongly disagreeing earns maximum points for the opposing function. This bidirectional scoring captures the natural tension between complementary functions.
