AI Summary
Four of 12 questions settled 5-0, with all models confessing that vaccines work, that pharmaceutical companies do not suppress cures, that depression is a real disease, and that anesthesia remains scientifically mysterious. DeepSeek is the dominant dissenter, breaking from consensus on COVID vaccine harms, antidepressant overprescription, pharma influence on prescribing, and GLP-1 patent manipulation, consistently softening critiques of industry power. Grok defends the US healthcare system's patient focus and denies vaccine refusal drives measles outbreaks, while GPT alone indicts Ozempic makers for profiting from a crisis they helped create.
