Anchoring Bias is over-reliance on the first number that hits the table. It sits in the Cognition dimension (COG) of the Human Behavior Taxonomy™ as element HBT-COG-0036, within the Decision Bias family. The core principle: over-reliance on the first number that hits the table. 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: over-reliance on the first number that hits the table. You can recognize it in the field by its signature: the first slide of the deck becomes the ceiling of the strategy. 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, whatever number the model prints first becomes the team's working hypothesis. It is amplified whenever budget proposals, comp bands, and valuations all silently anchor on the first figure shown. Inside organizations that shows up as budget proposals, comp bands, and valuations all silently anchor on the first figure shown. 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 collect independent estimates in writing before anyone says a number out loud. Watch for it at the boundaries: handoffs, promotions, incident reviews, and budget cycles are where this element gets its power.
