Types · INFJ vs INTP
They differ on 2 of the four axes. Here's exactly where — and what tends to happen there.
INFJ: You read people, and you move toward a picture of how things should be. · INTP: You take ideas apart to see how they work inside, in no hurry to close.
Where they clash
Nature — Head vs. bond (INFJ: F · INTP: T · measures your Warmth)
INTP decides by logic and criterion; INFJ decides by people and harmony. The typical friction: the bluntness of INTP reads as coldness to INFJ, and the diplomacy of INFJ reads as circling to INTP. The trick isn't for one to convert the other: it's agreeing when the moment calls for truth without anaesthetic, and when it calls for care first.
Tactics — Plan vs. slack (INFJ: J · INTP: P · measures your Order & drive)
INFJ rests when there's a plan and closure; INTP breathes when options stay open. The typical friction: INFJ lives the "we'll see" of INTP as insecurity, and INTP lives the calendar of INFJ as a cage. They rhyme when INFJ builds the skeleton and INTP brings the ability to improvise when the plan (always) bends.

Where they rhyme
Mind (both I · measures your Social energy)
On Mind they land on the same side (I): both recharge alone: they understand each other without filling every silence, and they respect the cave without asking for explanations.
Energy (both N · measures your Imagination & openness)
On Energy they land on the same side (N): both live on ideas and possibilities: the conversation leaps from the concrete to the abstract without asking permission.
But neither of you is a box.
This compares the archetypal types. Any of your letters could be sitting on the edge (near the midpoint), and there the label loses its nuance. The honest move: measure your real traits and compare your prisms, not the labels.
