Why safety reports can't prove safety: the adversarial logic flaw

davidmanheim · x · 2026-10-19

AI safety researcher David Manheim, in a thread replying to @TheZvi, argues that reports claiming to demonstrate sufficient safety share a central logical flaw: you can never prove you didn't miss anything, but even a minimal security mindset shows this reasoning fails in adversarial settings — other actors, including the models themselves, will actively seek out unmitigated flaws.

He also flags two supplementary concerns: additional issues highlighted by Opus, and Simon Mendelson's criticisms of the ML R&D benchmark as a measure of real research-capability risk.
