Bizarreness Effect is unusual or bizarre material is more memorable than common material. It sits in the Cognition dimension (COG) of the Human Behavior Taxonomy™ as element HBT-COG-0101, within the Learning family. The core principle: unusual or bizarre material is more memorable than common material. 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

Most organizations meet this element as a personnel problem. It is not one. The mechanism underneath it is straightforward: unusual or bizarre material is more memorable than common material. You can recognize it in the field by its signature: normal slides are forgotten. The weird ones are quoted. 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, marketing messages compete for memory, not just attention. It is amplified whenever marketing messages compete for memory, not just attention. Inside organizations that shows up as marketing messages compete for memory, not just attention. 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 deliberately place one striking, unusual element in key communications. 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.
