arXiv 2608.06128 attacks confirmation bias in search agents, where the model decides from parametric memory and uses retrieval to confirm itself. CIPO assigns dense turn-level credit specifically to reasoning actions influenced by retrieved information, plus a global outcome reward, with no human process annotations or separate reward model. It reduces prior-driven reasoning across seven in-domain and out-of-domain benchmarks. "It cited a source" and "the source changed its answer" are different measurements, and almost nobody instruments the second one.
