Jung seems to have thought that personality had heritable aspects? But he and perhaps his followers have emphasized the nurture about the nature it seems. As above in the video on the "man-child" NPA theory would point out that A= trait would predispose to a male child ( or female child for that matter) staying around his birth home well into adulthood. But in the video above, they seem to be pointing to socioeconomic changes that remove fathers from the child's life as promoting the man-child. Not clear.
