Lock-in Effect is customers become trapped in a product due to switching costs or network effects. It sits in the Cognition dimension (COG) of the Human Behavior Taxonomy™ as element HBT-COG-0450, within the Economics family. The core principle: customers become trapped in a product due to switching costs or network effects. 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: customers become trapped in a product due to switching costs or network effects. You can recognize it in the field by its signature: the hotel is fine. The door just does not open from the inside. 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, lock-in creates profits but also resentment. It is amplified whenever lock-in creates profits but also resentment. Inside organizations that shows up as lock-in creates profits but also resentment. 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 be transparent about switching costs and deliver value that earns loyalty. 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.
