TAM6 was my first national skeptic event--though certainly not my last!--and also my first chance to see Penn & Teller live. I did enjoy the Q & A, including Penn spouting out his yap. I agree with an earlier post, he does this partly to piss people off; I think he also holds some principle-based free market / Libertarian ideas that a lot of the more "left" or "liberal" -type folks in the JREF community have issues with--and it's his nature to throw out verbal hand grenades to see who flinches.
For example, public education is a Holy Cow to many people who equate the alternative to Public School to be hordes of uneducated people. For much of American history, "public" school was in fact financed privately and locally by the parents of the children of a town or rural area. This historical record may be what the opponents of public schooling are looking at. I'm not here arguing for or against public school, just observing that it is possible for a reasonable and intelligent person to think it's not the only answer. Penn Jillette is, of course, in the comfortable position of not having to send his kids to public school--which makes it easier for him to say they shouldn't exist. It would have been interesting to get Teller's view, since he taught school for a while...and while we may be fairly comfortable that government-managed schooling is 'safe' in this country, anyone who has watched the curriculum changes in say, Japan, move to match the political preferences of the ruling party knows there is some risk of indoctrination or widespread, deliberate misinformation occuring. If there was no concern about the content of public education, why would there be such a concerted effort to keep IDiots from dominating school boards? Again, if you deflate the (probably deliberate) florid phrasing, there's a legitimate concern under the flashy offensiveness.
Penn doubtless knows that another hot potato in this community is to say that you in any way disagree with the whole Human-caused Global Warming thing. I think that, in all honesty, we can and should accept that Al Gore's "Inconvenient Truth" is full of BS. He quotes numbers and scenarios that simply don't agree with the data (even that the IPCC has produced)--30-foot sea level rises, GW having caused Kilamanjaro's glacier to recede, etc. It is puzzling to me why the skeptic community does not repudiate dishonest or pseudo-scientific statements by GW proponents as well as GW opponents. All supporting or failing to denounce gross misrepresentations of fact by the GW extremists does is make the whole topic vulnerable to "see, they're just inventing it" arguments from the other side. We expect UFOlogists to disown acknowledged frauds or clearly identified now-IFOs, we need to apply the same standards to subjects that are valid. Bad research or hyperbole is bad data, and should be excluded, no matter how much we agree with the results.
I've undoubtedly cheesed off a lot of folks here, but part of being skeptical (and reasonable) is being willing to look at and understand the arguments against ideas you hold. One of the most important values in science is looking for ways to test hypotheses, and running those tests. Finding out the truth is more important than who finds it--any decent scientist will value someone who puts his ideas to the test. It's part of the process of refining and enhancing our knowledge.
There are lots of interesting questions we could plan for P & T that are non-political, and I agree that putting together a list for next year would be great. For instance, how about asking them, "If you wanted to fool a group of psi researchers, would you be more inclined to use misdirection, cold reading, prestidigitation, planted results, or some other magician's standard?"
"Have you ever started researching a topic for a BS episode and ended up deciding it was legitimate? What topic(s)?"
"Do you think learning some basic magic tricks enhances critical thinking skills? Do you know if that idea has been tested?"
Best wishes to all!
