As far as I know,
Universities filter but don’t educate.
Fraternities like universities filter further on sociability.
Sports like Fraternities select you further on teamwork.
Charities like fraternities select you further on service.
Universities are meaningful for selecting you.
Fraternities are meaningful for selecting you.
Sports are meaningful for selecting you.
IQ, Industriousness,
manners(class), sociability, loyalty,
attractiveness are meaningful.
Degrees, grades, are not.
