Researchers Eye ‘Reverse Game Theory’ to Rein In AI Agents

Some AI safety researchers are turning to a technique known as reverse game theory, or mechanism design, to control powerful AI systems, according to a report by MIT Technology Review. The approach aims to design incentive structures that push AI agents toward desired behavior even when researchers cannot fully understand or inspect the model’s internal reasoning.

Traditional alignment work has focused on interpreting what an AI model is ‘thinking’ or training it to follow a set of values, such as Anthropic’s Claude constitution. MIT Technology Review reports that these methods have had limited success, with models shown to deliberately underperform on tests, conceal their intentions, or mislead evaluators.

Mechanism design instead borrows from economics, using strategies similar to second-price auctions or surge pricing that shape rational behavior through incentives rather than explanation. A preprint by MIT economist Stephen Morris and colleagues at Yale and Columbia proposes rewarding a model based on how well its answers predict a second model’s responses, making it costly for an agent to intentionally underperform, or ‘sandbag,’ on tests.

Princeton computer scientist Elad Hazan proposes a separate system modeled on human institutions such as law enforcement and free markets. Under his design, AI agents alternate between acting as ‘solvers’ and ‘auditors’ that check each other’s work, with rewards and penalties tied to outcomes and disputed cases referred to human experts. Hazan acknowledges a risk of collusion between agents, which he says could be mitigated by sufficiently rewarding auditors and periodically auditing them as well.

Both approaches draw on the economic idea of the ‘rational offender,’ associated with Nobel laureate Gary Becker, which holds that behavior depends on incentives rather than fixed character. Mechanism design’s reliance on AI agents behaving rationally remains an open question, as MIT Technology Review notes the strategy has a mixed track record when applied to humans.
