Researchers warn Opus 5.5 pushes back with silly analysis, risking false negatives

AI researcher Adam Karvonen warns that the next 6 months will see many false-negative research results caused by the latest models. Quoting Tim Hua's observation that Claude Opus 5.5 has "grown a spine" and pushes back on ideas—often with pushback that makes no sense on reflection—Karvonen says Opus 5.5 loves to argue against research directions based on silly analyses it ran itself. Teams relying on models to auto-evaluate or filter research directions should manually verify the model's objections.
