Ingroup Favoritism is we favor members of our own group over outsiders. It sits in the Cognition dimension (COG) of the Human Behavior Taxonomy™ as element HBT-COG-0406, within the Social family. The core principle: we favor members of our own group over outsiders. 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 is straightforward: we favor members of our own group over outsiders. You can recognize it in the field by its signature: we are the best team because we are us, and they are them. 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, ingroup bias limits diversity and innovation. It is amplified whenever ingroup bias limits diversity and innovation. Inside organizations that shows up as ingroup bias limits diversity and innovation. 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 use structured criteria and diverse interview panels. Treat it as infrastructure. Once you can see it in your own system, most of the argument about culture resolves itself.
