Acton's Dictum is power tends to corrupt, and absolute power corrupts absolutely. It sits in the Cognition dimension (COG) of the Human Behavior Taxonomy™ as element HBT-COG-0008, within the Social family. The core principle: power tends to corrupt, and absolute power corrupts absolutely. 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
Most organizations meet this element as a personnel problem. It is not one. The mechanism underneath it is straightforward: power tends to corrupt, and absolute power corrupts absolutely. You can recognize it in the field by its signature: give someone a crown and watch the halo slip. 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, concentrated decision rights erode judgment over time. It is amplified whenever concentrated decision rights erode judgment over time. Inside organizations that shows up as concentrated decision rights erode judgment over time. 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 distribute power and rotate who holds the veto. Treat it as infrastructure. Once you can see it in your own system, most of the argument about culture resolves itself.
