Pollyanna Principle is we tend to remember pleasant information more accurately than unpleasant information. It sits in the Cognition dimension (COG) of the Human Behavior Taxonomy™ as element HBT-COG-0534, within the Learning family. The core principle: we tend to remember pleasant information more accurately than unpleasant information. 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: we tend to remember pleasant information more accurately than unpleasant information. You can recognize it in the field by its signature: memory is an optimist with a good editor. 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, rosy retrospection limits learning. It is amplified whenever rosy retrospection limits learning. Inside organizations that shows up as rosy retrospection limits learning. 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 document failures and challenges in real time. Measure the behavior, not the sentiment. A survey will tell you how people feel about this; only observed action tells you whether it changed.
