Precise but Uncoupled: Reviewer Precision Does Not Guarantee Critique Uptake in Multi-Agent Math Reasoning

Explain Like I'm Normal

New research shows that hierarchical 'Reviewer' agents are surprisingly bad at fixing errors in complex math problems despite being technically accurate. The study found that flat, peer-to-peer discussion outperforms structured pipelines because the 'actor' agents often ignore precise feedback. For builders, this suggests that agentic workflows should favor open collaboration over rigid, top-down instruction.
