If a person can't verify the validity of the assertion, is it any wonder they will base their opinion on the proposed solutions?
A person is told the sky is falling. They can't verify it, but are told the potential consequences.
Then the person is told the 'needed' solution, say, cut off everbody's right leg.
Well the cure sounds pretty bad, and the impact of the cure on the person is very clear.
So two possibilities: one is unverifiable, the other well understood. Which one would a person choose?
Science and politcs, the former deals in speculation, the latter in tangible consequences. There should not be tangible consequences to mere speculation. That is just wrong-headed. History is replete with examples of 'scientifically supported' facts, resulting in barbaric consequences eg. the atrocities of WWII. We can look back _now_ and say 'the science was wrong', but _at the time_ the science was held up as the justification for action.
