Soft-spoken, dutiful protectors: one letter and a world apart.
The core difference
The perceiving engine: ISFJ's Si guards what has been proven; INFJ's Ni is pulled by what hasn't happened yet.

Change: ISFJ adapts reluctantly, INFJ initiates it
- 3
ISFJs trust experience; INFJs trust the pattern behind it
