Tacit Knowledge is knowledge that is hard to transfer because it is personal and experience-based. It sits in the Cognition dimension (COG) of the Human Behavior Taxonomy™ as element HBT-COG-0656, within the Learning family. The core principle: knowledge that is hard to transfer because it is personal and experience-based. 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: knowledge that is hard to transfer because it is personal and experience-based. You can recognize it in the field by its signature: you cannot learn to ride a bike by reading a manual. 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, tacit knowledge walks out the door when experts leave. It is amplified whenever tacit knowledge walks out the door when experts leave. Inside organizations that shows up as tacit knowledge walks out the door when experts leave. 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 create apprenticeship, mentoring, and knowledge-capture rituals. The leverage is not in explaining the behavior to people. It is in changing what the behavior earns.
