Mind — The social tempo (ESTJ: E · INFP: I · measures your Social energy)

ESTJ recharges with people and thinks out loud; INFP recharges alone and thinks before speaking. The typical friction: ESTJ floats the plan aloud and lives it as connection, while INFP receives it as noise when they're still ordering their thoughts. It works when ESTJ leaves silence without reading it as rejection, and INFP says out loud that they're processing, not disappearing.

Energy — Ideas vs. solid ground (ESTJ: S · INFP: N · measures your Imagination & openness)

INFP lives in the possible: patterns, connections, what could be. ESTJ lives in the tangible: the proven, the concrete, what already is. The typical friction: to ESTJ, the ideas of INFP sound like hot air until they land; to INFP, the pragmatism of ESTJ sounds like a handbrake. Together, if they listen, they're the idea-plus-execution pair; if they don't, a dialogue of the deaf.

Nature — Head vs. bond (ESTJ: T · INFP: F · measures your Warmth)

ESTJ decides by logic and criterion; INFP decides by people and harmony. The typical friction: the bluntness of ESTJ reads as coldness to INFP, and the diplomacy of INFP reads as circling to ESTJ. 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 (ESTJ: J · INFP: P · measures your Order & drive)

ESTJ rests when there's a plan and closure; INFP breathes when options stay open. The typical friction: ESTJ lives the "we'll see" of INFP as insecurity, and INFP lives the calendar of ESTJ as a cage. They rhyme when ESTJ builds the skeleton and INFP brings the ability to improvise when the plan (always) bends.
