AI research agents should search independently before comparing notes, a post argues

A post about ArcticSwarm argues that early collaboration can steer research agents toward the same plausible but wrong answer instead of different possibilities. It reports 82.6% accuracy on BrowseComp-Plus with Qwen 3.5-27B, falling to 78.8% without search isolation and 74.5% when the review system was also removed. According to the post, 40 independent single-agent runs combined by majority vote reached 63.5%. Its takeaway for difficult research tasks without a reliable verifier: let agents explore separately, then challenge and verify the leading answer before agreeing.
