Interpersonal Foundation

The Interpersonal or Social Foundation refers to the impulse we have as humans to consider our relationships in the decision-making process. In what some choose to describe as "selfishness," humans always intend on making the choices which are best for the self, including the people we choose to allow to reaffirm our existence, such as friends, family members, or romantic partners.

Survivalism posits that everything we do as a species, including the simple act of conversation or the advent of written language itself, is driven by the need to survive. The Sex and Stories (SnS) idea elaborates that our main functions in life are to reproduce and subsequently prepare the offspring to do the same without our presence. Given this, relationships are essentially intended to be mutually beneficial arrangements in which each party reaffirms the ability of the others to successfully survive.

Humor
It is well known among comedians that the art of a joke lies in creating a mental gap for the audience to close, what is known as "getting" the joke. The more gaps you can get the audience to close at once (per the idea of the "callback"), the funnier you are. If the gap is too wide, as in a too-obscure reference, no one gets it, and if it is too narrow, as in the pun, it becomes a "groaner," the groan itself being a human vocalization which essentially communicates, "you made me believe I was going to get to close a gap and feel smart but instead you delivered this joke that only someone who had just learned what language was would find entertaining."
