Context Effects (Choice) is preference between two options depends on what other options sit beside them — attraction, compromise, similarity effects. It sits in the Environment dimension (ENV) of the Human Behavior Taxonomy™ as element HBT-ENV-0003, within the Decision family. The core principle: preference between two options depends on what other options sit beside them — attraction, compromise, similarity 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
This is one of the elements leaders describe as a values gap. It is a payoff gap. The mechanism underneath it is straightforward: preference between two options depends on what other options sit beside them — attraction, compromise, similarity effects. You can recognize it in the field by its signature: add a worse option; the middle one suddenly looks brilliant. 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, pricing-tier design, menu engineering, plan comparisons. It is amplified whenever pricing-tier design, menu engineering, plan comparisons. Inside organizations that shows up as pricing-tier design, menu engineering, plan comparisons. 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 design the choice set deliberately. Decoys are tools — but cynical ones erode trust. 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.
