Congratulations, you may be psychic!

Weekly World News, that bastion of scientific credibility, has reported that 53% of people are psychic, based on a study done at the University of Virginia on the townspeople and students of Charlottesville.

Say what now?

This study was published by the "parapsychology division of the University of Virginia School of Medicine" in the Journal of the American Society for Psychical Research. Although the article does not name specific researchers from the study, the division of which they speak is most likely the Division of Perceptual Studies, founded by Ian Stevenson in 1967. Dr. Stevenson was a psychiatrist and researcher who devoted decades of work to collecting past-life experiences and evidence of reincarnation. Unfortunately, though he carried out this work all over the globe until his retirement in 2002, he did not produce scientifically compelling evidence to back claims of such experiences. I encourage you to read his entry in Bob Carroll's Skeptic's Dictionary, which is fascinating and quite thoroughly researched. He also co-founded the Society for Scientific Exploration, which is deserving of a separate post, already in the works and long overdue. (I've been busy... yadda yadda...)

Naturally, the UVa library has a subscription to the journal, so I look forward to finding it in the Alderman stacks later this week when I get a chance. Unfortunately, I can't find a version online, or even an abstract at the moment. According to the article, however, the study was a self-reported survey of 622 participants. Until I get a look at how the participants were selected, it's hard to say whether this is an accurate cross-section of the American population, as is claimed. (Maybe we are just special?) One researcher is quoted in the article as saying,
50% of America is psychic – the results of this survey confirm this fact.
I'm skeptical that any researcher into the paranormal would make such a sweeping and incorrect statement, especially if they expect to be taken seriously. The lack of a name attached to the quote only encourages my notion that this was made up whole cloth by a "reporter". At any rate, a self-reporting survey is no way to prove that a phenomenon exists. Serious scientific studies need to be double-blinded and carefully controlled before a claim can be shown to have validity. Participants in this survey report such paranormal experiences as déjà vu, out of body experiences, apparitions, hauntings, and more. Although these may be terrifying to a person in the moment, a more rational explanation is often to be found. A few years ago, a team of neuroscientists reported that they may have found a biological cause for that eerie feeling of déjà vu. Paranormal investigators such as Joe Nickell have found rational explanations for many hauntings and paranormal claims over the decades. Many psychics have stepped up to take James Randi's Million Dollar Challenge, and none have passed preliminary testing. If half of us were psychic, someone would have noticed by now.

So, this article was published in a cheesy tabloid with a screaming, Vulcan-ish child on the logo. So what? Most people running across this article will snicker and move on. A small percentage, no doubt, will add it to the pile of "evidence" for their already-cherished beliefs in the paranormal. I'm more interested, personally, in what the survey-study itself has to say, and how much more widely it is reported, especially locally.

Muchas gracias to cvillenews.com for the link! Also, kudos to them on the clever title.

Nuns taking backseat to Nones




According to the American Religious Identification Survey 2008, available at http://www.americanreligionsurvey-aris.org, the percentage of Americans claiming no religion has now increased to 15 percent.

However, the acutal number of those who claim to be atheist is still small. The report stated that 1.6 percent of Americans call themselves atheist or agnostic, but based on stated beliefs, 12 percent are atheist (no God) or agnostic (unsure), while 12 percent more are deistic (believe in a higher power but not a personal God). The number of outright atheists has nearly doubled since 2001, from 900,000 to 1.6 million.

Additionally, within the Christian segment, the subset of "non-denominational Christians" increased to 2.5 million in 2008 from 200,000 in 1990. The report suggested that this growth is associated with increased megachurch attendance.

While many have wondered if the declining economy and hard times will cause folks to cling tight to religion, the Pew Forum notes that church attendance is largely unchanged.

In related news, one of UVA's own writes about how the Obama administration may contribute to the decline of religion at http://blog.christianitytoday.com.

Molecule self-replicates in lab



IT'S ALIVE!!!!

"Obviously what we're trying to do is make a biology," says Gerald Joyce, a biochemist at the Scripps Research Institute in La Jolla, California. He hopes to imbue his team's molecule with all the fundamental properties of life: self-replication, evolution, and function.

Whole story:
