Personal Incredulity is i can't imagine how it works, therefore it doesn't. It sits in the Cognition dimension (COG) of the Human Behavior Taxonomy™ as element HBT-COG-0523, within the Relevance Fallacy family. The core principle: i can't imagine how it works, therefore it doesn't. 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: i can't imagine how it works, therefore it doesn't. You can recognize it in the field by its signature: 'That's impossible' is rarely an argument. 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, investment decisions throttled by imagination, not analysis. It is amplified whenever investment decisions throttled by imagination, not analysis. Inside organizations that shows up as investment decisions throttled by imagination, not analysis. 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 make the desired behavior observable, remove whatever currently pays for its opposite, and attach the reward to the behavior rather than to the noisy outcome downstream of it. Measure the behavior, not the sentiment. A survey will tell you how people feel about this; only observed action tells you whether it changed.

- Investment decisions throttled by imagination, not analysis.
- How do you design around Personal Incredulity?
- Name the behavior you want in observable terms, remove what currently pays for the opposite, attach the reward to the behavior rather than a lagging proxy, and publish how you will detect gaming.
