In-Group Bias is we extend more trust, benefit of the doubt, and rope to 'our people.'. It sits in the Social dimension (SOC) of the Human Behavior Taxonomy™ as element HBT-SOC-0018, within the Social Bias family. The core principle: we extend more trust, benefit of the doubt, and rope to 'our people.'. 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
This is one of the elements leaders describe as a values gap. It is a payoff gap. The mechanism underneath it is straightforward: we extend more trust, benefit of the doubt, and rope to 'our people.'. You can recognize it in the field by its signature: the same memo from a tribe member is sharper than from an outsider. Every element in the Social 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, aI teams hire only people who think like AI teams. The blind spots compound. It is amplified whenever talent pools narrow without anyone deciding to narrow them. Inside organizations that shows up as talent pools narrow without anyone deciding to narrow them. 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 structured interviews. Diverse panels. Blind work samples. Watch for it at the boundaries: handoffs, promotions, incident reviews, and budget cycles are where this element gets its power.
