Hi, Ed - another good one from you, so thanks. Are you familiar with this Galen Winsor talk? Regarding the Carl Sagan segment: We may be experiencing the illusory truth effect in action - it seems possible that a lie was repeated for years about the existence of nuclear weapons. Galen says there are none. Right up your alley, if you haven't already seen it.
Thanks heaps, no I have not listened to it - but that will change tonight when I watch it thanks so much :)
Turns out that is a different talk than the one I was thinking of, and I can't find the other! Still, there are a couple of good documentaries making the case that nuclear weapons don't exist. We love fear porn!
