Zero-Risk Bias is we prefer eliminating a small risk completely over reducing a larger one partially. It sits in the Cognition dimension (COG) of the Human Behavior Taxonomy™ as element HBT-COG-0711, within the Probability Bias family. The core principle: we prefer eliminating a small risk completely over reducing a larger one partially. 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
Executives usually notice this element only after it has cost something. By then it looks like a one-off. It is not. The mechanism underneath it is straightforward: we prefer eliminating a small risk completely over reducing a larger one partially. You can recognize it in the field by its signature: we'll spend $10M to make a 1% risk a 0% risk and ignore the 20% one entirely. 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, aI guardrails over-engineered for rare hallucinations; real misuse goes unpriced. It is amplified whenever risk theater that consumes capacity without reducing exposure. Inside organizations that shows up as risk theater that consumes capacity without reducing exposure. 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 risk-weight every dollar of mitigation against expected loss reduction. Watch for it at the boundaries: handoffs, promotions, incident reviews, and budget cycles are where this element gets its power.
