Because INFJs pair extroverted feeling with introverted intuition, they have an incredible ability to “mind read”, or so it would seem to outside observers. Attending to the nuances of people’s body language, facial expressions, and voice intonation, they infer - usually very accurately - how others are really doing. They read between the lines and depend more on nonverbal information than on the words they hear. As a result, they’re often extremely perceptive and great at helping people work through problems.
