Scope Creep is projects gradually expand beyond their original goals. It sits in the Cognition dimension (COG) of the Human Behavior Taxonomy™ as element HBT-COG-0598, within the Systems family. The core principle: projects gradually expand beyond their original goals. 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: projects gradually expand beyond their original goals. You can recognize it in the field by its signature: the project was small. Then it had feelings. Then it had features. 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, scope creep is the default state of projects. It is amplified whenever scope creep is the default state of projects. Inside organizations that shows up as scope creep is the default state of projects. 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 lock scope with change-control processes and visible costs. Watch for it at the boundaries: handoffs, promotions, incident reviews, and budget cycles are where this element gets its power.
