Spillover Effect is effects of an intervention spread to other areas beyond the intended target. It sits in the Emotion dimension (EMO) of the Human Behavior Taxonomy™ as element HBT-EMO-0009, within the Systems family. The core principle: effects of an intervention spread to other areas beyond the intended target. 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: effects of an intervention spread to other areas beyond the intended target. You can recognize it in the field by its signature: fix one thing, break another. Or help another. Every element in the Emotion 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, local changes have systemic consequences. It is amplified whenever local changes have systemic consequences. Inside organizations that shows up as local changes have systemic consequences. 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 map second-order effects before rolling out changes. 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.
