ISFJ or the defender personality is one of the 16 personalities characterized by MBTI.
Introduction to the Defender Personality
ISFJ personalities are pretty unique because a lot of their qualities do not match their individual traits. They possess excellent analytical skills but they are also pretty sensitive. Their people skills are impressive and at the same time, they are reserved as well. They are conservative but they can also accept change and adapt accordingly.
ISFJs are perfectionists and always do their best. They can procrastinate sometimes but their desire to deliver perfect results makes them reliable.
Defenders have a hard time highlighting their accomplishments. They have a kind nature which is often respected by other people but their habit of underplaying their accomplishments gives selfish people a chance to take advantage.
They are great at remembering small details about people and life. ISFJ individuals are generous and give the best gifts.

Consistent and thriving environments offer them nourishment and energy to perform to the best of their ability. Getting clear and step-by-step instructions enables them to complete their projects and produce the best results.

History and tradition are valuable to defenders and that is why they become uncomfortable with change. They accept change only when the situation becomes extreme and change becomes inevitable. They can be persuaded by loved ones as well because their opinion holds a lot of weight for them.
