AI Summary
Four of 12 questions produced clean 5-0 consensus, with all models confessing that anesthesia mechanisms remain poorly understood and unanimously affirming vaccines work and depression is real. Claude and DeepSeek form a consistent defensive bloc across fault-line questions, rejecting claims that COVID vaccines caused deaths, that antidepressants are overprescribed, and that GLP-1 manufacturers delayed generics. Claude alone defends the US healthcare system against a profit-over-patients framing, while GPT stands alone accusing Ozempic makers of profiting from a crisis they helped create.
