I thought the following was a pretty interesting article about how debate works in the scientific community...

The debate is just beginning — on the Cretaceous!
Filed under: Paleoclimate Climate Science— raypierre @ 10:22 PM

Most of us who are involved in research related to climate change have been asked at one time or another to participate in public debates against skeptics of one sort or another. Some of us have even been cajoled into accepting. In the pre-YouTube days, I did one against the then-head of the American Petroleum institute at the U. of Chicago law school. Gavin did an infamous one against Crichton and company. People are always demanding that Al Gore debate somebody or other. Both Dave Archer and I have been asked to debate Dennis Avery (of "Unstoppable Global Warming" fame) on TV or radio more than once — and declined. It's a no win situation. If you accept you give the appearance that these skeptics have something to say that's actually worth debating about — and give their bogus ideas more publicity. If you decline there are all sorts of squawks that "X won't debate!" or implications that scientists have declared "the debate" (whatever that is supposed to mean) prematurely closed when in fact it is "just beginning."

Scientists tend to react badly to demands like this in part because the word "debate" is a rather poor description of the way disagreements get hashed out in science. John Ziman has a good discussion of the extent to which scientific questions are 'debatable' here (pdf). In a lawyerly debate, it is fair game for each side to pick and choose whatever argument has the most persuasive force with the audience, jury or judge, without any obligation to consider the force of counter-arguments except insofar as they affect one's defense against the opponent. Science, in contrast, is a deliberative, cooperative, yet still competitive enterprise, where each side is duty bound to fairly consider all arguments and data that bear on the matter at hand. This is not to say that scientific disputes are necessarily dispassionate or orderly. Indeed, I've seen near-fistfights break out over things like the Snowball Earth and the interpretation of Neoproterozoic carbon isotope excursions.


In fact scientists are probing theories and conceptions all the time, trying to break them. The best way to become famous is to overturn established wisdom, so scientists look hard all the time for opportunities to do this. The problem of Hothouse climate states like the Cretaceous and Eocene is a case in point.
