Affect Heuristic is feelings act as shortcuts for facts. It sits in the Cognition dimension (COG) of the Human Behavior Taxonomy™ as element HBT-COG-0017, within the Decision Bias family. The core principle: feelings act as shortcuts for facts. 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: feelings act as shortcuts for facts. You can recognize it in the field by its signature: if it feels safe, it must be smart. 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, aI that 'feels' helpful trusted past its actual reliability. It is amplified whenever vibes-based investment decisions wrapped in spreadsheet theater. Inside organizations that shows up as vibes-based investment decisions wrapped in spreadsheet theater. 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 separate the analysis step from the decision step. Sleep on it. Watch for it at the boundaries: handoffs, promotions, incident reviews, and budget cycles are where this element gets its power.
