Working Memory is limited capacity holding-tank for current information. It sits in the Biology dimension (BIO) of the Human Behavior Taxonomy™ as element HBT-BIO-0084, within the Cognition family. The core principle: limited capacity holding-tank for current information. 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 operates in the Biology dimension — what does the body contribute?. You can recognize it in the field by its signature: roughly 4 ± 1 items. That's it. Every element in the Biology 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, workflow design that respects working memory limits. It is amplified whenever workflow design that respects working memory limits. Inside organizations that shows up as workflow design that respects working memory limits. 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 externalize. Chunk. Sequence. 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.
