In one paragraph

Either-Or Trap (more refined false dichotomy) is constraining the option set to bias the decision. It sits in the Cognition dimension (COG) of the Human Behavior Taxonomy™ as element HBT-COG-0265, within the Definition Fallacy family. The core principle: constraining the option set to bias the decision. In incentive terms, it matters because it changes the payoff people perceive before they choose — which means it can be designed for, or exploited.

Lab Commentary

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: constraining the option set to bias the decision. You can recognize it in the field by its signature: two options is a sales technique, not a strategy. 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, option-set engineering is more powerful than option-set analysis. It is amplified whenever option-set engineering is more powerful than option-set analysis. Inside organizations that shows up as option-set engineering is more powerful than option-set analysis. 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 make the desired behavior observable, remove whatever currently pays for its opposite, and attach the reward to the behavior rather than to the noisy outcome downstream of it. The leverage is not in explaining the behavior to people. It is in changing what the behavior earns.
