Context Effect is environmental factors influence perception and judgment. It sits in the Environment dimension (ENV) of the Human Behavior Taxonomy™ as element HBT-ENV-0002, within the Decision family. The core principle: environmental factors influence perception and judgment. 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 is straightforward: environmental factors influence perception and judgment. You can recognize it in the field by its signature: the same wine tastes different in a crystal glass versus a plastic cup. Every element in the Environment 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, context changes value, not just presentation. It is amplified whenever context changes value, not just presentation. Inside organizations that shows up as context changes value, not just presentation. 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 test offers in the actual environment where they will be judged. The leverage is not in explaining the behavior to people. It is in changing what the behavior earns.
