Liking Bias is we're more persuaded by people we like. It sits in the Social dimension (SOC) of the Human Behavior Taxonomy™ as element HBT-SOC-0019, within the Social Bias family. The core principle: we're more persuaded by people we like. 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: we're more persuaded by people we like. You can recognize it in the field by its signature: the right vendor with the wrong rep loses to the wrong vendor with the right rep. Every element in the Social 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 partner chosen because the AE is charming. It is amplified whenever decisions influenced by relationships more than results. Inside organizations that shows up as decisions influenced by relationships more than results. 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 blind scoring. Decisions made before relationships deepen. Treat it as infrastructure. Once you can see it in your own system, most of the argument about culture resolves itself.
