For INFJ personality types and INFP personality types, the fawning response is most often a result of trauma in childhood. However, a consistent fawning response can also come about in relationships due to self-worth issues, and not feeling understood by others.
Fawning is an extreme form of people-pleasing, and when INFJ personality types and INFP personality types use this type of strategy in relationships, we signal to the other person that we will do anything to placate them and make them happy. INFJ personality types and INFP personality types use the fawning response to stay in control of interactions and manage the unpredictable moods of others, especially if those others are narcissistic personality types.
