The INTP tends to be the most introverted among all the introvert personality types on the MBTI. They prefer spending time alone and often find social interactions draining. This introversion is a result of their dominant function, Introverted Thinking (Ti), which leads them to focus inwardly on analyzing and understanding their own thoughts and ideas. 1. INTPs tend to have a small circle of close friends. 2. They often enjoy solitary activities such as reading, writing, or pursuing intellectual interests. 3. INTPs may struggle with small talk and find it difficult to initiate conversations with strangers. Their introspective nature allows them to delve deep into complex subjects, making them excellent problem solvers and critical thinkers. However, it's important for INTPs to balance their need for solitude with opportunities for social interaction in order to maintain a healthy overall well-being.
