There is no single Myers-Briggs Type Indicator (MBTI) type that can be considered the most intelligent. The MBTI is a psychological assessment tool that is used to determine people's preferences and personalities. It is based on the four dichotomies of extraversion vs introversion, sensing vs intuition, thinking vs feeling, and judging vs perceiving. Each of these four dichotomies has two opposing preferences, which gives a total of sixteen different personality types.
Each personality type has its own unique strengths and weaknesses that can affect intelligence. For example, an individual with an Introverted Sensing Thinking Judging (ISTJ) personality type might be very good at analyzing facts and data, while an individual with an Extraverted Intuitive Feeling Perceiving (ENFP) personality type might be better at coming up with innovative ideas.
Therefore, there is no single MBTI type that can be considered the most intelligent. The best way to determine which MBTI type is the most intelligent for a particular individual is to assess their individual strengths and weaknesses.
