Among the 16 Myers-Briggs Type Indicator (MBTI) personality types, the type that is most similar to an INTJ (Introverted, Intuitive, Thinking, and Judging) is the INTP (Introverted, Intuitive, Thinking, and Perceiving).
INTJs and INTPs share the same dominant cognitive function, which is Introverted Thinking (Ti). This function is characterized by a strong emphasis on logical analysis, categorizing information, and seeking to understand the underlying principles governing the world. Both types tend to be intellectually curious, enjoy deep thinking, and value knowledge and expertise.
However, there are some key differences between INTJs and INTPs, mainly related to their auxiliary functions:
INTJs: Their auxiliary function is Extraverted Intuition (Ne). This function allows INTJs to explore possibilities and future scenarios, often contributing to their strategic planning and visionary abilities. They tend to have a more focused and goal-oriented approach to problem-solving.
INTPs: Their auxiliary function is Extraverted Intuition (Ne). This function also allows INTPs to explore possibilities and generate ideas, but it may manifest more as playful curiosity rather than the strategic foresight of an INTJ. INTPs are often described as flexible, open-minded, and interested in exploring various ideas for the sake of knowledge.
In summary, while INTJs and INTPs share some similarities in their thinking-oriented approach to the world, they can exhibit different behaviors and priorities due to their contrasting auxiliary functions. It's essential to remember that each person is unique, and individuals within the same personality type can still have significant variations in their attitudes and behaviors.
