Alternative Blindness is forgetting to compare an offer with the next-best alternative. It sits in the Cognition dimension (COG) of the Human Behavior Taxonomy™ as element HBT-COG-0028, within the Decision family. The core principle: forgetting to compare an offer with the next-best alternative. 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: forgetting to compare an offer with the next-best alternative. You can recognize it in the field by its signature: a great deal compared to what?. 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, every yes is implicitly a no to the next option you didn't price. It is amplified whenever every yes is implicitly a no to the next option you didn't price. Inside organizations that shows up as every yes is implicitly a no to the next option you didn't price. 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 require at least one named alternative on every material decision. Design against it the way you would design against a known failure mode — assume it will appear, and price the exploit before someone finds it.
