Parenthetical factoids makes for lazy teaching
Matt Lowry has just posted a brief article, Can Science Test the Validity of the Supernatural? in JREF, the blog of the James Randi Educational Foundation. Lowry “is a [suburban Chicago] high school & college physics professor with a strong interest in promoting science education, skepticism and critical thinking among his students and the population in general.” It is well written. This part caught my attention:
. . . For example, while the Catholic Church can tell its followers that the science for evolution is ironclad and therefore acceptable, that same religious institution routinely turns its back on science and completely ignores it regarding questions related to the authenticity of supposed religious relics such as the Shroud of Turin (which is, in case you didn’t know, a fake). This is merely one example where the believers and purveyors of the supernatural will try to have their cake and eat it too, . . .
It brings to mind the high school student in Alaska who was forced to take a lower grade in a chemistry class for refusing to accept that science had proven that the shroud was a fake. This was so even after she brought in a copy of Scientific Method Applied to the Shroud of Turin – A Review by Ray Rogers and Anna Arnoldi and insisted that her objection was strictly scientific and not religious.

Is the Shroud real? Probably.
The Shroud of Turin may be the real burial cloth of Jesus. The carbon dating, once seemingly proving it was a medieval fake, is now widely thought of as suspect and meaningless. Even the famous Atheist Richard Dawkins admits it is controversial. Christopher Ramsey, the director of the Oxford Radiocarbon Laboratory, thinks more testing is needed. So do many other scientists and archeologists. This is because there are significant scientific and non-religious reasons to doubt the validity of the tests. Chemical analysis, all nicely peer-reviewed in scientific journals and subsequently confirmed by numerous chemists, shows that samples tested are chemically unlike the whole cloth. It was probably a mixture of older threads and newer threads woven into the cloth as part of a medieval repair. Recent robust statistical studies add weight to this theory. Philip Ball, the former physical science editor for Nature when the carbon dating results were published, recently wrote: “It’s fair to say that, despite the seemingly definitive tests in 1988, the status of the Shroud of Turin is murkier than ever.” If we wish to be scientific we must admit we do not know how old the cloth is. But if the newer thread is about half of what was tested – and some evidence suggests that – it is possible that the cloth is from the time of Christ.
No one has a good idea how front and back images of a crucified man came to be on the cloth. Yes, it is possible to create images that look similar. But no one has created images that match the chemistry, peculiar superficiality and profoundly mysterious three-dimensional information content of the images on the Shroud. Again, this is all published in peer-reviewed scientific journals.
We simply do not have enough reliable information to arrive at a scientifically rigorous conclusion. Years ago, as a skeptic of the Shroud, I came to realize that while I might believe it was a fake, I could not know so from the facts. Now, as someone who believes it is the real burial shroud of Jesus of Nazareth, I similarly realize that a leap of faith over unanswered questions is essential.

I sense the skepticism in his words, but definately no critical thinking. I wouldn’t want my kid in his class.
