Iceberg Model is below visible events sit patterns, structures, and mental models — each layer more leveraged than the last. It sits in the Cognition dimension (COG) of the Human Behavior Taxonomy™ as element HBT-COG-0378, within the Systems family. The core principle: below visible events sit patterns, structures, and mental models — each layer more leveraged than the last. 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: below visible events sit patterns, structures, and mental models — each layer more leveraged than the last. You can recognize it in the field by its signature: reacting to events is firefighting. Changing mental models is system change. 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, quarterly reviews almost always operate at the event layer. Strategy lives below. It is amplified whenever quarterly reviews almost always operate at the event layer. Strategy lives below. Inside organizations that shows up as quarterly reviews almost always operate at the event layer. Strategy lives below. 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 for any recurring problem, ask: what patterns? what structures? what beliefs? Intervene at the deepest layer you can reach. 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.
