Types · INFJ vs INFP
Near twins: they share three of the four axes. The whole difference lives in Tactics.
INFJ: You read people, and you move toward a picture of how things should be. · INFP: You filter the world through what matters to you, and it has to fit your values.
Where they clash
Tactics — Plan vs. slack (INFJ: J · INFP: P · measures your Order & drive)
INFJ rests when there's a plan and closure; INFP breathes when options stay open. The typical friction: INFJ lives the "we'll see" of INFP as insecurity, and INFP lives the calendar of INFJ as a cage. They rhyme when INFJ builds the skeleton and INFP 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.
Nature (both F · measures your Warmth)
On Nature they land on the same side (F): both put people at the centre when they decide: harmony isn't an extra, it's part of the outcome.
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.
