That's true of most frequently referenced elements of human nature, if not all of them.

Even Love.

~The Homo Sapiens Class has a trusted computing override that enables it to lock itself into a state of heightened agreeability towards a particular target unit. More to the point: it can signal this shift in modes in a way that is both recognizable to other units, and which the implementation makes very difficult for it to forge. The Love feature then provides HS units on either side of a reciprocated Love signalling a means of safely cooperating in extremely high-stakes PD scenarios without violating their superrationality circumvention architecture.

Hmm.. On reflection, one would hope that most effective designs for time-constrained intelligent(decentralized, replication-obsessed) agents would not override superrationality("override": Is it reasonable to talk about it like a natural consequence of intelligence?), and that, then, the love override may not occur.

Hard to say.
