Reinforcing Loop is output amplifies input — virtuous or vicious cycle. It sits in the Cognition dimension (COG) of the Human Behavior Taxonomy™ as element HBT-COG-0580, within the Systems family. The core principle: output amplifies input — virtuous or vicious cycle. 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
The mistake with this element is treating it as irrationality. It is almost always a rational response to a payoff nobody wrote down. The mechanism underneath it operates in the Cognition dimension — how do we think?. You can recognize it in the field by its signature: compound interest is the same shape as compound rot. 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, engagement loops can flip from growth to harm without changing equation. It is amplified whenever reinforcing loops feel like 'momentum' until they don't. Inside organizations that shows up as reinforcing loops feel like 'momentum' until they don't. 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 install governors and circuit breakers before exponential phases. The leverage is not in explaining the behavior to people. It is in changing what the behavior earns.
