Merchants of Doubt: How a Handful of Scientists Obscured the Truth on Issues from Tobacco Smoke to Global Warming

with Naomi Oreskes and Erik M. Conway
Sunday, September 12, 2010 at 2 pm

ORESKES AND CONWAY tell an important story about the misuse of science to mislead the public on matters ranging from the risks of smoking to the reality of global warming. The people the authors accuse are themselves scientists — mostly physicists, former cold warriors who now serve a conservative agenda, and vested interests like the tobacco industry. And they name names, documenting their involvement in such issues as acid rain, the dangers of smoking and secondhand smoke, the ozone hole, global warming, the Strategic Defense Initiative, and the banning of DDT. These scientists aimed to sow seeds of public doubt on matters of settled science by casting aspersions on the science and the scientists who produce it. Oreskes, a professor of history and science studies at U.C. San Diego and science writer Conway also emphasize how journalists and Internet bloggers uncritically repeat these charges.

Broadcasting from the Great Beyond

a book review by Donna Harris

What happens to us when we die? This has to be one of humanity’s greatest questions. After all, once you find out, there’s no way to let anyone else in on the answer.

Pim van Lommel is a cardiologist from the Netherlands. During his long career, he has resuscitated untold numbers of cardiac arrest survivors, and became intrigued by their stories of Near Death Experiences (NDEs). In addition to reviewing the available literature and past studies, in 2001 van Lommel’s interest drove him to lead his own larger study of cardiac arrest patients. While that study was published in the prestigious British medical journal Lancet, and van Pommel has published scientific papers and authored chapters in other medical works, this is his first book.

The book itself is readable and organized. We’re led deeper into the subject, as the author first establishes a historical foundation by recounting a description of the NDE phenomenon, then lays the groundwork for his theory, which essentially applies quantum physics to biological systems. The early chapters on the actual reported contents of NDEs are an entertaining primer through these experiences.

It’s easy to agree with his observation that NDEs occur when the brain is essentially stopped. If there is no blood flow, and no electrical activity, how can the cells in the brain continue to register visual and auditory input?

Van Lommel’s answer is that consciousness is not just located in the brain, but is a result of electro-magnetic fields that hold experiences and are non-local and possibly eternal. He asserts the analogy that much like a TV or radio station continues to broadcast even when we have no receiver to pick up the station, our consciousness continues to function after the death of the body and brain.

As the reader progresses through the book, there are questions not addressed that detract from the author’s message. The fact that all the research is far from gold-standard double-blind studies, but is instead based on self-reported surveys and interviews — in many cases years after the initial event — casts serious doubt on the accuracy of those memories.

Van Lommel also mentions an increase in “psychic” or intuitive abilities by NDErs, without even blinking a skeptical eye. Since any type of paranormal or intuitive power remains unproven, it is troubling that the author doesn’t question these abilities, and just includes them as accepted facts.

Van Lommel’s theories of the origins of consciousness are based on theories in quantum physics and the role of DNA. The lay reader can only assume that van Lommel is interpreting the theories correctly, since he himself is not a physicist or an evolutionary biologist, but a medical doctor. But they make for interesting, if not challenging, reading. Be prepared for your brain to hurt, and some readers may want to review these sections more than once.

Consciousness Beyond Life (book cover)

Another area that deserves further exploration involves the differences between survivors. In his own study, van Lommel reports that of 344 cardiac arrest survivors, 62 patients (18%) reported a Near Death Experience. However, that still leaves 82% (282 patients) who didn’t. And there were no striking differences between the two groups, such as duration of arrest, medication used, etc. If van Lommel’s theory is correct, what accounts for the different experiences? Why were the radio stations of the non-NDE patients not broadcasting?

Despite the fact that Van Lommel fails to convince skeptical readers that his ideas and theories are correct, the author remains sympathetic in that he doesn’t take an aggressive, “here’s my magic answer” approach. He clearly states that he is presenting a hypothesis and, as far as the lay reader can tell, it appears to be worthy of more exploration and consideration, even though some may argue the whole idea lacks plausibility.

Overall, the book is an interesting exploration of the phenomenon of the near death experience, and worth the read if you wish to think and be challenged. But in the end he did not convince this skeptic.


Skeptical perspectives on NDEs, consciousness and the paranormal
DVD cover Altered States and the Quest for Immortality

Skepticality

David Aaronovitch
Voodoo History

Historical precedent, eyewitnesses, academic experts — these are among the tools that critical thinkers use to verify facts and give credibility to their arguments. And yet, misuse of these same principles provides the foundation for widely accepted conspiracy theories.

Why does the public often prefer wildly improbable half-truths to the demonstrable facts of history? This week on Skepticality, Swoopy talks with award-winning journalist and author David Aaronovitch about his book Voodoo Histories: The Role of Conspiracy Theory in Shaping Modern History. Deconstructing both well-known and obscure conspiracies, David illuminates how such far-fetched claims come to be believed.

MonsterTalk

Dr. Naish
Cryptozoology & Science

What is cryptozoology? Is it science? Is it folklore? Does it make predictions?

In part 1 of a 2-part series, MonsterTalk examines cryptozoology as a field, including speculation on the cryptids most likely to turn out to be real. Guest Dr. Darren Naish, paleontologist and science blogger, makes some surprising statements about the field, its role in science and culture, and the intersection of amateur and professional science.

Our Neandertal Brethren

Around 400,000 years ago a population of hominids migrated northward through the Middle East and into Europe and parts of western Asia. Between 80,000 and 50,000 years ago another population from the ancestral continent journeyed a similar route into the Eurasian landmass, and there the two populations met and mated. We are their descendants. Don’t miss this revealing article from Michael Shermer’s August Scientific American column.

    One can easily have the out of body experience that comes with the near death experience. Just subject the body to a continuous high-G environment with out taking any measures to keep the blood flowing to the head.

    In the gray-out that occurs, first one gets tunnel vision, then, as the blood flow is restricted to the brain, the vision becomes even more tunnel-like and slowly narrows to a point, then, as one starts to lose consciousness, the mind interprets that as the mind floating away from the body.

    As long as the brain has the oxygen flow reduced, even though death doesn’t occur, the fantasy continues. Not all the brain functions are lost, because hearing is still operating, but what a person hears is interpreted in a dissociated way.

    That’s why I remain skeptical of near-death experiences. My opinion is that they are only the mind trying to make sense of unfamiliar inputs.

    • Marcel says:

      The way you describe it, it seems, with the “tunnel” narrowing, that the person losing consciousness is “moving away” from the tunnel.

      I thought people who’ve had NDE’s describe moving towards a tunnel / going through it ?

      Just my 2c.

  2. Olaf Branstrom says:

    My comment was also meant to apply to near death experience. I maintain that it’s just a part of the body’s physiological response to decreased blood flow to the brain. As a matter of fact, I also maintain that it is also similar to the brain’s response to a general anesthesia.

    Hi,

    I am keen to get transcripts of forthcoming lectures at Caltech esp. by Dawkins , Sam Harris ,Kevin Kelly & Mlodinov .

    Is it possible at all ?
