Behavioral Game Theory is game theory adjusted for how humans actually play — including fairness, reciprocity, and limited reasoning. It sits in the Social dimension (SOC) of the Human Behavior Taxonomy™ as element HBT-SOC-0004, within the Strategy family. The core principle: game theory adjusted for how humans actually play — including fairness, reciprocity, and limited reasoning. 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: game theory adjusted for how humans actually play — including fairness, reciprocity, and limited reasoning. You can recognize it in the field by its signature: homo economicus loses to a college student in real experiments. 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, negotiation, pricing, and competitive strategy modeled with realistic counterparties. It is amplified whenever negotiation, pricing, and competitive strategy modeled with realistic counterparties. Inside organizations that shows up as negotiation, pricing, and competitive strategy modeled with realistic counterparties. 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 strip homo economicus assumptions out of your strategy game tree. Measure the behavior, not the sentiment. A survey will tell you how people feel about this; only observed action tells you whether it changed.
