Scientists report Opus 5.5 refusing ordinary research work.

A neuroscience user's r/ClaudeAI post says the model raised safety alarms when asked to look at a file or give a session status update, and the thread's summary of 50+ comments found users in life sciences, neuroscience and ML reporting the same. Commenters said Claude Science carries identical restrictions and Anthropic's life-sciences verification program only admits whole organizations, leaving individual grad students and postdocs out. On a day of mostly praise, this was the clearest counter-signal, and the thread's answer was open-weight Qwen.
