Belief Perseverance is beliefs survive the evidence that should have killed them. It sits in the Identity dimension (IDN) of the Human Behavior Taxonomy™ as element HBT-IDN-0004, within the Belief Bias family. The core principle: beliefs survive the evidence that should have killed them. 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
Most organizations meet this element as a personnel problem. It is not one. The mechanism underneath it is straightforward: beliefs survive the evidence that should have killed them. You can recognize it in the field by its signature: some convictions outlive their own data by a decade. 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, continuing to claim 'AI doesn't apply here' three years past contradiction. It is amplified whenever strategy frozen against reality because the founding belief is sacred. Inside organizations that shows up as strategy frozen against reality because the founding belief is sacred. 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 set kill criteria in advance for every belief that drives capital allocation. 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.
