In this unscripted episode, Glenn Campbell discusses the role of personality in the formation and maintenance of his hypothetical post-nuclear family system. Discussion includes MBTI, the Five Factor Model, the Dark Triade traits and other recognized personality disorders.

As an addendum to the previous episode, Glenn Campbell provides a 6th reason that parents should not live with their children in the post-nuclear family: It insulates the children from the parents' disputes. The children's household is governed by rules established and enforced by the adults. With multiple parents, there are bound to be disputes on matters of policy and on specific conflicts. These should be debated and resolved outside the hearing of the children, which is less likely if multiple parents are living in the house. Children should also be insulated from the ups and downs of their parents' personal relationships. Under the traditional nuclear family, divorce or open conflict between the parents can be devastating to the children. In the post-nuclear family, a divorce among the parents would have little impact on the kids. They'll still see both parents, but maybe not on at the same time. — Twitter: @DemographicDoom — See the YouTube version of this episode for notes, comments, corrections & links to resources: j.mp/dd_disputes [ep 63, 16 July 2021]

In an unscripted episode, Glenn Campbell answers a question about his theoretical post-nuclear family system: Why he believes the parents should not live in the same household as the children. He cites 5 reasons: ① to preserve the child-friendly culture and physical features of the main household, ② to encourage division of labor among the adults, ③ to insulate the children from the parents' wealth, ④ to encourage the independence of the children's household, ⑤ to facilitate a work-self-family balance among the adults. Although adults would not normally occupy the same dwelling as the kids, Glenn cites two exceptions: the elderly or sick who require care, and where necessary for physical protection. If the elderly and sick live in adjacent quarters, the children can assist in their care. There might be more physical distance between parents and children in safe societies, and less in unsafe ones. Finally, Glenn returns to ①, discussing the intentional isolation of the children's household. — Twitter: @DemographicDoom — See the YouTube version of this episode for notes, comments, corrections & links to resources: j.mp/dd_noadults [ep 62, 15 July 2021]
