AI as Coach vs. AI as Replacement is augmentation strategy vs. substitution strategy. It sits in the Incentives dimension (INC) of the Human Behavior Taxonomy™ as element HBT-INC-0016, within the Strategy family. The core principle: augmentation strategy vs. substitution strategy. 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
When this element shows up in a diagnostic, the instinct is to train people out of it. Training rarely moves it. The mechanism underneath it operates in the Incentives dimension — what makes behavior more or less likely?. You can recognize it in the field by its signature: coach increases the median. Replacement raises the floor. Every element in the Incentives 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, strategic positioning of AI in workflows. It is amplified whenever strategic positioning of AI in workflows. Inside organizations that shows up as strategic positioning of AI in workflows. 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 choose deliberately. Don't drift between them. The leverage is not in explaining the behavior to people. It is in changing what the behavior earns.
