KISS Principle is keep it simple, stupid. Simplicity beats complexity in design and communication. It sits in the Cognition dimension (COG) of the Human Behavior Taxonomy™ as element HBT-COG-0423, within the Reasoning family. The core principle: keep it simple, stupid. Simplicity beats complexity in design and communication. 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: keep it simple, stupid. Simplicity beats complexity in design and communication. You can recognize it in the field by its signature: if you need a diagram to explain it, you have already lost. 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, complexity is a tax on execution and adoption. It is amplified whenever complexity is a tax on execution and adoption. Inside organizations that shows up as complexity is a tax on execution and adoption. 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 force a one-page explanation of any plan or product. The test of any redesign here is simple: after the change, can you name what the organization is now doing less of? If not, the payoff structure did not actually move.
