I'm with James Miller and Caledonian on this one, and I want it taken further. Caledonian, I think the cognitive bias is good old repugnancy bias. How I'd like it taken further: I think what we want to avoid is not (1) horrific outcomes due to war from a specific type of technology, nor (2) horrific outcomes due to war generally, but (3) horrific outcomes generally. As such, beyond using nuclear weapons (which I'm not convinced prevents any of the three, though it may), how about greatly increasing the variety of human medical experimentation we engage in, including medical experimentation without consent, and breeding and cloning people, and making genetic knockout people and disease models of people to the extent that there will be a net decrease in horrific outcomes (death, suffering, etc.)? Sort of Dr. Ishii meets Jonas Salk.
