Tucker Carlson on Fox interviewed Bill Nye, the pseudo-science guy, recently, and absolutely skewered him. Nye tries the old “the science is settled” routine whereupon Carlson asks him how much global warming is due to humans, given that the climate has changed hugely for millions of years without human intervention.
Nye tries the appeal-to-authority argument and tries looking down his nose at Carlson. But Carlson will have none of it. Well, if the science is settled, then you must know what you’re talking about. But, obviously, Nye doesn’t.
To establish a hypothesis, or even give it some credibility, competing hypotheses must be ruled out. It’s no good claiming that the man-made global warming appears to be right (it doesn’t even do that), the others must be shown to be wrong.
Nye doesn’t understand the basics of the scientific approach because he is just a political robot. At the end, his mind just snaps and he starts rambling on about “political leaks etc.”
Scott Adams has analyzed this superbly and says that this is the best example of cognitive dissonance that he’s ever seen. Check them both out here.
