Ben Franklin Effect is we come to like people we've done a favor for, more than people who've helped us. It sits in the Cognition dimension (COG) of the Human Behavior Taxonomy™ as element HBT-COG-0096, within the Social family. The core principle: we come to like people we've done a favor for, more than people who've helped us. 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 come to like people we've done a favor for, more than people who've helped us. You can recognize it in the field by its signature: ask a small favor — you'll be liked more, not less. 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, strategic relationship-building runs backwards from intuition. It is amplified whenever strategic relationship-building runs backwards from intuition. Inside organizations that shows up as strategic relationship-building runs backwards from intuition. 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 routinely ask for small, specific help from people whose alignment you need. Design against it the way you would design against a known failure mode — assume it will appear, and price the exploit before someone finds it.
