False Dichotomy is presenting two options as the only possibilities. It sits in the Cognition dimension (COG) of the Human Behavior Taxonomy™ as element HBT-COG-0299, within the Relevance Fallacy family. The core principle: presenting two options as the only possibilities. 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: presenting two options as the only possibilities. You can recognize it in the field by its signature: 'Either we cut 20% or we go under.' (Or we think harder.). 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, eliminates the third, fourth, and best options before they're spoken. It is amplified whenever eliminates the third, fourth, and best options before they're spoken. Inside organizations that shows up as eliminates the third, fourth, and best options before they're spoken. 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. Measure the behavior, not the sentiment. A survey will tell you how people feel about this; only observed action tells you whether it changed.

Questions about False Dichotomy
- What is False Dichotomy?
- False Dichotomy is presenting two options as the only possibilities. It sits in the Cognition dimension (COG) of the Human Behavior Taxonomy™ as element HBT-COG-0299, within the Relevance Fallacy family. The core principle: presenting two options as the only possibilities. In incentive terms, it matters because it changes the payoff people perceive before they choose — which means it can be designed for, or exploited.
- What is an example of False Dichotomy?
- Eliminates the third, fourth, and best options before they're spoken. The Incentives Lab catalogs everyday, organizational, and historical instances of this element on its Human Behavior Taxonomy™ page (HBT-COG-0299).
- How is False Dichotomy exploited?
- Eliminates the third, fourth, and best options before they're spoken.
- How do you design around False Dichotomy?
- Name the behavior you want in observable terms, remove what currently pays for the opposite, attach the reward to the behavior rather than a lagging proxy, and publish how you will detect gaming.
- Which behavioral dimension does False Dichotomy belong to?
- False Dichotomy is classified in the Cognition dimension (COG) of the Human Behavior Taxonomy™, family "Relevance Fallacy", class "Logical Fallacy". Its permanent identifier is HBT-COG-0299 and its evidence grade is B.
