People with the ISFJ personality type (Defenders) share the Introverted, Observant, Feeling, and Judging personality traits.

ISFJs absorb and store information methodically, building an impressive mental database of what works and what doesn’t. Their contributions typically address practical considerations, potential implementation challenges, or historical context that others might overlook.
