![In a collaborative fire detection scenario, agents operating with incomplete and unshared information exhibit predictably inconsistent beliefs about environmental states - illustrated by heightened uncertainty regarding unobserved cells - leading to a reciprocal movement strategy that satisfies minimal rational agent consistency (MRAC); however, when assessed within a fully observable multi-agent partially observable Markov decision process (MPOMDP), the system’s collective knowledge reveals that certain cells ([latex]C[/latex]) possess a demonstrably higher degree of uncertainty than others ([latex]A[/latex] and [latex]B[/latex]), prompting a coordinated shift in observational focus toward those critical areas.](https://arxiv.org/html/2512.20778v1/figures/example-selected-full2.png)

![Ablation studies reveal a complex interplay between biases affecting perceptions of education and demographic groups, demonstrating that interventions minimizing both [latex] KL [/latex] divergences-representing ideal outcomes-are possible, though frequently traded off against scenarios where one bias diminishes while the other intensifies, and occasionally resulting in the amplification of both.](https://arxiv.org/html/2512.20796v1/plots/tradeoff_bottom_panels1.png)
