INTJs at School
(See Play.) Myers et al. (1998) examined the leisure pastimes of the sixteen types. The type that liked the item "Taking classes" most was the INTJ. And not only did they like taking classes the most, but they liked it more than any other type liked any other activity. INTJs liked taking classes more than ESTPs liked playing sports. INTJs liked taking classes more than INFJs liked writing (but only just barely). It would seem that taking classes deserves the status of "passion" for INTJs. No other type liked any other thing as much.
Perhaps it comes as no surprise that INTJs tend to have the highest grades of all types (Myers et al., 1998). Three studies on type and IQ have found that INTJs tend to place between first and third/fourth place in the group (McCaulley & Kainz, 1976; McCaulley & Natter, 1974; Myers in Myers & McCaulley, 1985).
