Confirmation Bias is we hunt for evidence that we were right all along. It sits in the Identity dimension (IDN) of the Human Behavior Taxonomy™ as element HBT-IDN-0006, within the Belief Bias family. The core principle: we hunt for evidence that we were right all along. 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 hunt for evidence that we were right all along. You can recognize it in the field by its signature: pre-mortems become rituals to bless decisions already made. Every element in the Identity 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, prompts engineered — sometimes unconsciously — to extract the answer the leader wants. It is amplified whenever strategy reviews stack the room with people who already agree. Inside organizations that shows up as strategy reviews stack the room with people who already agree. 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 assign a paid devil's advocate. Reward dissent in public, not in performance reviews. Measure the behavior, not the sentiment. A survey will tell you how people feel about this; only observed action tells you whether it changed.
