[ISFJ] Defender. Introverted Sensory Type with Extroverted Emotion (MBTI)
ISFJs are Si-Fe cognitive functionaries, so they make decisions on how best to respond to others based on past experiences and facts, taking into account the feelings and needs of others. My impression is that the word 'dedication' best fits this type; ISFJs are highly dependent on others and desire for approval, for better or worse, and their own intentions and wishes tend to be vague because 'what I want to do = the role expected of me by those around me'.
