If you force an AI to overthink a problem for too long, it'll eventually talk itself out of the right answer and choose something stupid.

FoE: Forest of Errors Makes the First Solution the Best in Large Reasoning Models

The Takeaway
It contradicts the popular 'test-time scaling' trend, showing that refining an initial hunch is often more reliable than generating many alternatives. This discovery could make reasoning models much faster and more accurate by trimming wasted effort.
From the abstract
Recent Large Reasoning Models (LRMs) like DeepSeek-R1 have demonstrated remarkable success in complex reasoning tasks, exhibiting human-like patterns in exploring multiple alternative solutions. Upon closer inspection, however, we uncover a surprising phenomenon: The First is The Best, where alternative solutions are not merely suboptimal but potentially detrimental. This observation challenges widely accepted test-time scaling laws, leading us to hypothesize that errors within the reasoning pat
