But the scientists are faced with a conundrum, here.  When they do proper science, "Evolution is a theory", they get attacked for it by bombastic blowhards - "It's just a THEORY!".  So they've been forced into adopting some marketing principles simply to get their voices heard.<p>Meanwhile, it seems that everybody's lost their mind about the whole purity factor.  If you give them, say, a 50% chance of being right, when "right" means trillions of dollars of damage, common sense says we should be doing something.  Yet we're spending all our time arguing over whether they have a 100% chance of being right or not.  That's because the people on the other side of the argument are not arguing in good faith - many of them have a direct financial or ideological stake in the matter and science is the furthest thing from their minds.
