Where they overlap
INTP and INFP share 3 core preferences. They tend to gravitate toward similar environments, similar work, and similar people. To outsiders they can look nearly identical — which is why they are commonly confused.
Where they diverge most
Primary divergence: T/F. INTPs decides by logic first, evidence before empathy; INFPs decides by values first, impact on people before efficiency. 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 T/F flip. Ask yourself: When you hit a hard call, do you anchor on what is logically correct (T) or on impact on the people involved (F)?
When in doubt, take the 60-second test — it scores word patterns and preference signals rather than abstract self-description.
