Grade Inflation is professors rewarded by student evaluations have an incentive to inflate. It sits in the Incentives dimension (INC) of the Human Behavior Taxonomy™ as element HBT-INC-0140, within the Education Perverse Pattern family. The core principle: professors rewarded by student evaluations have an incentive to inflate. 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
This element is common enough to feel like human nature and specific enough to be engineered around. The mechanism underneath it is straightforward: professors rewarded by student evaluations have an incentive to inflate. You can recognize it in the field by its signature: the customer is always right, even when the customer is supposed to be learning. 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, signaling value erodes as inflation continues. It is amplified whenever signaling value erodes as inflation continues. Inside organizations that shows up as signaling value erodes as inflation continues. 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 normalize by cohort. Externally validated assessment. The leverage is not in explaining the behavior to people. It is in changing what the behavior earns.
