The ingrained nature of EFS is extraverted feeling, hence they are capable of seeing the goodness and ideal nature of everything and everyone in their life. They can connect to everyone with empathy and rejoice in the people to people contact. They also value customs and traditions as they bring pictures of gatherings of people as well as reasons for harmony.
The associative function of EFS is introverted sensing, which means EFS have strong memory of things that affect them, both positive and negative. Combined with ingrained Fe, they generally remember all the important details of people around them and also important details like birthdays of near and dear ones without fail. They are also quite tolerable of rule based systems as they can understand them and provide well defined mechanisms of reward and failure.
Extraverted intuition forms the exploratory of EFS, so they get excited by new possibilities, like meeting new people, visiting new places, trying out new food etc. They are also likely to keep their guard on while doing so, as the exploratory Ne is likely to be reminded of the past times when things went sour while looking for novelty.
Regulatory of EFS is made up of introverted thinking, which creates models of things and people around and is used to understand and fine tune EFS’s primary interests. Here Ti is not used in its full ability as a source of rational understanding, but merely to help understand why EFS’s expectations of people turn out right or wrong, which is their primary interest. When things don’t go along the lines of EFS’s expectations, these models are called into action as EFS tries to revise their understanding. They get disappointed if they can’t find suitable explanation and hence can get hurt easily by unkindness and indifference, causing them to block the sources of these negative experiences out of their life.
