In one paragraph

Texas Sharpshooter Fallacy is cherry-picking data to fit a pattern after the fact. It sits in the Cognition dimension (COG) of the Human Behavior Taxonomy™ as element HBT-COG-0666, within the Reasoning family. The core principle: cherry-picking data to fit a pattern after the fact. In incentive terms, it matters because it changes the payoff people perceive before they choose — which means it can be designed for, or exploited.

Lab Commentary

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: cherry-picking data to fit a pattern after the fact. You can recognize it in the field by its signature: draw the target around the bullet holes and call yourself a marksman. 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, post-hoc pattern finding is not prediction. It is amplified whenever post-hoc pattern finding is not prediction. Inside organizations that shows up as post-hoc pattern finding is not prediction. 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 test patterns on new data and require pre-registration. 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.
