Bottlenecks is a system's throughput is constrained by its single slowest step. It sits in the Cognition dimension (COG) of the Human Behavior Taxonomy™ as element HBT-COG-0108, within the Systems family. The core principle: a system's throughput is constrained by its single slowest step. 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 is straightforward: a system's throughput is constrained by its single slowest step. You can recognize it in the field by its signature: optimize everything except the bottleneck and you've optimized nothing. 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, find the bottleneck or you will spend money in the wrong place. It is amplified whenever find the bottleneck or you will spend money in the wrong place. Inside organizations that shows up as find the bottleneck or you will spend money in the wrong place. 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 apply Theory of Constraints quarterly: identify, exploit, subordinate, elevate. 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.
