The Journey Within

The 16 types

The four temperaments

Four core needs divide the 16 types into four families. Inside each family, two pairs of functions give two different ways of living that need.

Four core needs

Long before the cognitive functions became popular, the psychologist David Keirsey grouped the types into four temperaments by what they most need: the intuitive feelers (NF) need meaning, the intuitive thinkers (NT) mastery, the sensing judgers (SJ) stability and the sensing perceivers (SP) freedom. He drew on an idea as old as Greek medicine: four basic temperaments in human nature. The DTI test uses the same four groups.

Seen with the functions, each family splits in two, by the two functions that lead its types. This chapter follows those eight families.

Temperament and the journey

Each temperament's core need is also what its journey puts to the test. The NF's meaning must find a body, the NT's mastery must find a heart, the SJ's stability must open to change, and the SP's freedom must find a direction. The other three needs are the road.
