About the ISFJ (The Defender) Personality Type
ISFJ — the Defender — is the personality of devoted service. Around 13-14% of the population, ISFJs combine introverted sensing with extraverted feeling: they remember birthdays, anticipate needs, and quietly hold institutions together. Famous ISFJs include Queen Elizabeth II, Mother Teresa, Rosa Parks, and characters like Samwise Gamgee, Hufflepuff house figures, and Captain America. ISFJs are the type most likely to be the backbone of a family, a hospital, or a long-running team.
