No, they measure different things. The Myers-Briggs Type indicator (MBTI) attempts to classify an individual’s personality according to four variables: introvert or extravert, sensing or intuitive, thinking or feeling, and judging or perceiving. Since there are four categories, each with two choices, there are 24 or 16 possible personality types in this rubric. If the MBTI classifies you as an intuitive, rather than a sensing individual, it means that you tend to trust your intuition more than direct sensory experience. You will tend to see the big picture and be more interested in general trends and patterns than in the what you perceive directly through your senses. In short, you will be more inclined to a figurative interpretation of the world over a literal interpretation. However, the results of MBTI should not be taken to too seriously, because research in this area has shown that MBTI does not have much reliability in predicting behavior. MBTI was based on Carl Jung’s classification of people according to how they process and manage their perceptions. A more scientifically validated personality assessment is the so-called “Big Five personality traits” classification.
Fluid intelligence, on the other hand is the kind of cognitive capacity that is measured on IQ tests. This is the ability to problem solve, see patterns in data, draw inferences from complex information, form generalizations from specific observations, and think abstractly. Being intuitive and having the ability to move beyond direct observation to more abstract conceptual understanding is compatible with a higher fluid intelligence. That is, a person with a high fluid intelligence (IQ) is more likely to be oriented to a figurative rather than a literal interpretation of the world, but MBTI categories in general have little or no correlation with fluid intelligence.
