Appeal to Majority is claiming something is true or better because most people believe it. It sits in the Cognition dimension (COG) of the Human Behavior Taxonomy™ as element HBT-COG-0047, within the Reasoning family. The core principle: claiming something is true or better because most people believe it. 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
Executives usually notice this element only after it has cost something. By then it looks like a one-off. It is not. The mechanism underneath it is straightforward: claiming something is true or better because most people believe it. You can recognize it in the field by its signature: a billion flies can be wrong. 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, strategy by herd is strategy by accident. It is amplified whenever strategy by herd is strategy by accident. Inside organizations that shows up as strategy by herd is strategy by accident. 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 ask what the majority actually knows that you don't. Measure the behavior, not the sentiment. A survey will tell you how people feel about this; only observed action tells you whether it changed.
