Where they diverge most
Primary divergence: N/S. INTPs leads with patterns and abstractions; ISTPs leads with concrete details and lived experience. This shows up in leadership style, how they handle conflict, and how they recover from stress.
How to tell which one you are
The decisive tell is the N/S flip. Ask yourself: When you read a new idea, do you reach for the abstract pattern first (N) or the concrete example first (S)?
When in doubt, take the 60-second test — it scores word patterns and preference signals rather than abstract self-description.
