Hippocampus is brain structure central to memory formation, spatial navigation, and learning. It sits in the Cognition dimension (COG) of the Human Behavior Taxonomy™ as element HBT-COG-0366, within the Memory family. The core principle: brain structure central to memory formation, spatial navigation, and learning. 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: brain structure central to memory formation, spatial navigation, and learning. You can recognize it in the field by its signature: smaller when stressed. Larger in London cab drivers. 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, learning system design has biological substrates worth respecting. It is amplified whenever learning system design has biological substrates worth respecting. Inside organizations that shows up as learning system design has biological substrates worth respecting. 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 protect sleep, novelty, and exercise — all build hippocampal capacity. The leverage is not in explaining the behavior to people. It is in changing what the behavior earns.
