Cognitive Functions

For insight

The eight Jungian cognitive functions — the mental processes behind the 16 types. Each is a way of taking in information (the four perceiving functions: Ni, Ne, Si, Se) or making decisions (the four judging functions: Ti, Te, Fi, Fe). 32 statements rank them into your function stack (dominant → inferior). A companion to the 16-type tests — original items, indicative, not a validated instrument.

In plain English

Goes a layer deeper than the usual 16-types result: instead of four letters, it ranks the eight “mental habits” you actually think with — like big-picture intuition, hands-on realism, cool logic or people-warmth — from your strongest right down to your blind spot.
