A new research paper titled "Disparity Laundering" reveals that multi-agent clinical AI systems, even when designed to average out errors, do not eliminate bias and can even amplify it. Experiments on MIMIC-IV data showed that demographic swaps consistently led to Black patients receiving more acute triage, regardless of model or aggregation topology. The study found that late-stage fairness interventions were ineffective, and the only successful mitigation involved making the bias visible through diverse-perspective ensembles that pooled counterfactual versions at every decision round.
