INFJ personality types and INFP personality types are two of the most intuitive personality types in the MBTI personality type system. Many people believe that the intuition of INFJ personality types and INFP personality types comes from both types being very observant, and subconsciously picking up on physical cues. While this is partly true, there is more to the intuition of INFJ personality types and INFP personality types than information that comes through only the five senses.
