Penn and Teller explain sleight of hand in three minutes

Penn and Teller's explanation of sleight of hand is delightful. You get the whole lecture in about three minutes. As entertaining as this video is, it could also serve to remind us of a set of principles by which humans deceive each others through fallacious and misleading arguments. Because we are creatures of limited attention and growing fatigue, we are vulnerable to cognitive misdirection much as we are vulnerable to prestidigitation. For more on human attentional limitations, see here. Further, I have given considerable thought to the idea that much human decision-making could be explained in terms of attentional limitations. For more, see this paper I wrote in 1996.

A bit of sanity re eight babies sharing a womb

I'm delighted to see that people are raising some pointed criticisms about the single woman with six children who decided to fill her womb with octuplets, endangering them in the process and hogging neonatal resources. This commentary is by Thomas H. Murray of the Hastings Center, in an article published by CNN:

The point of infertility treatment, after all, is to create a child. But that child-to-be is not the clinic's patient -- the would-be parents are. I believe that the interests of those children deserve at least as much consideration as the wishes of the prospective parents.

The vast majority of infertility patients are no doubt fierce advocates for the well-being of the child they so earnestly seek to bring into their lives. What happens, though, when the client's request shows little consideration or regard for the welfare of the would-be children? What happens if a woman in her early 30s with six children wants eight embryos implanted all at once?

61 degrees

My family is keeping our thermostat at 61 degrees this winter. We decided to bring it down from our traditional 65 degrees in order to save energy. [Note: Late at night at my house, the temperature automatically drops down to 55]. I've put a thermometer in various rooms to check the accuracy of the thermostat. The actual daytime temperature ranges from 59 to 62 in the various rooms. When we are all gone for the day, we manually set the temperature down to 55. When I mention "61 degrees" to people, most of them are surprised; some of them are aghast. Apparently, at least among Americans, 61 degrees is an usually "cold" temperature for the interior of a house in the winter. Over the past couple of weeks, I even heard from several people who keep their thermostats above 70. When you browse the Internet, you will find numerous "authorities" advising you to set the thermostat down to 65 to save energy (e.g., here). Here's an informal survey of quite a few folks. Apparently, even our new energy-conscious President likes it toasty indoors.

Post on Bart Ehrman’s Misquoting Jesus is open for more comments

About two years ago, I read a terrific book by Bart Ehrman: "Misquoting Jesus: The Story Behind Who Changed the Bible and Why." Ehrman is a bible scholar who concluded that in the past 2,000 years, the New Testament has been changed in thousands of minor ways and dozens of major ways. He therefore put up a caution sign to all of those believers who claim that the Bible is inerrant. "Which version of the Bible?" is always an important clarifying question. Here's the link to my post, which I titled: "Who changed the Bible and why? Bart Ehrman’s startling answers." More than 540 comments were quickly contributed to this post, making this page too long to download and display. The phenomenon of the passionate flood of comments confounded me. Many of the comments were irrational, in that the writers had clearly not even read my post (or the book). They argued about things that Ehrman (and I) did not claim and they failed to address Ehrman's meticulous scholarship. For technical reasons I closed off new comments back in March 2007. Last night, I discovered a WordPress plugin that allows me to paginate comments, thereby protecting this website from the sudden and repeated load of 540 comments displayed on one page. Here's the good news, then. Anyone who has not yet had his or her chance to comment on Bart Ehrman's book may now jump in at the original post and post a comment. That's right! If the 540 comments that came before you didn't address an important aspect of Bart Ehrman's book, you may now remedy that omission in the comments to the original post. Godspeed.
