Kin Selection is behavior that benefits genetic relatives at cost to oneself. It sits in the Cognition dimension (COG) of the Human Behavior Taxonomy™ as element HBT-COG-0422, within the Evolution family. The core principle: behavior that benefits genetic relatives at cost to oneself. In incentive terms, it matters because it changes the payoff people perceive before they choose — which means it can be designed for, or exploited.

Original analysis from The Incentives Lab — how this element behaves inside real payoff structures.
Why this element matters to incentive design
When this element shows up in a diagnostic, the instinct is to train people out of it. Training rarely moves it. The mechanism underneath it operates in the Cognition dimension — how do we think?. You can recognize it in the field by its signature: hamilton's rule beats HR's handbook. Every element in the Cognition dimension changes the perceived payoff of an action before the action happens, which is exactly where incentive design has leverage.
How it gets exploited
Left undesigned, anthropomorphized AI gets kin-like loyalty it hasn't earned. It is amplified whenever founders treat early hires like kin; the dynamic breaks at scale. Inside organizations that shows up as founders treat early hires like kin; the dynamic breaks at scale. The pattern is the same one Goodhart's Law describes: the measurable proxy attracts the effort, and the purpose behind it quietly loses funding.
How the Lab designs around it
The redesign move is to don't assume institutional loyalty inherits the warmth of kin loyalty. Measure the behavior, not the sentiment. A survey will tell you how people feel about this; only observed action tells you whether it changed.
