Actor-Observer Bias is we attribute our own actions to situations but others' actions to their character. It sits in the Cognition dimension (COG) of the Human Behavior Taxonomy™ as element HBT-COG-0009, within the Social family. The core principle: we attribute our own actions to situations but others' actions to their character. 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
The mistake with this element is treating it as irrationality. It is almost always a rational response to a payoff nobody wrote down. The mechanism underneath it is straightforward: we attribute our own actions to situations but others' actions to their character. You can recognize it in the field by its signature: i am late because of traffic. You are late because you are careless. 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, performance reviews are riddled with this double standard. It is amplified whenever performance reviews are riddled with this double standard. Inside organizations that shows up as performance reviews are riddled with this double standard. 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 force the same causal language for self and others. Watch for it at the boundaries: handoffs, promotions, incident reviews, and budget cycles are where this element gets its power.
