When Introverted Sensing takes over, the INFP’s functions work in reverse order—Te dictates Fi, rather than the other way around, and Si feeds into Ne. Their reversed function stacking makes them resemble their dichotomous four-letter opposite, the ESTJ. However, the INFP’s under-exercised Te does not function with the precision and capability that the ESTJ’s dominant Te does—they will therefore behave as an unhealthy or imbalanced ESTJ.
