Altruism is sacrificing for others without expecting a personal reward. It sits in the Cognition dimension (COG) of the Human Behavior Taxonomy™ as element HBT-COG-0030, within the Social family. The core principle: sacrificing for others without expecting a personal reward. 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
Executives usually notice this element only after it has cost something. By then it looks like a one-off. It is not. The mechanism underneath it is straightforward: sacrificing for others without expecting a personal reward. You can recognize it in the field by its signature: neoclassical economics struggled with this for decades. 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, pro-social behavior inside organizations is real — and systematically underweighted in incentive design. It is amplified whenever pro-social behavior inside organizations is real — and systematically underweighted in incentive design. Inside organizations that shows up as pro-social behavior inside organizations is real — and systematically underweighted in incentive design. 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 design for it. Don't price it away with extrinsic incentives. Design against it the way you would design against a known failure mode — assume it will appear, and price the exploit before someone finds it.
