Chris Mooney vs Atheists: Part XXXIV

 
Chris Mooney is at it again. His latest posting sounds ominous: Are Top Scientists Really So Atheistic? Look at the Data.
Elaine Howard Ecklund is a sociologist at Rice University; we cited her work on the topic of science and religion in Unscientific America. Now, she is out with a book that is going to seriously undercut some widespread assumptions out there concerning the science religion relationship.
Unfortunately, Chris doesn't present any data because he's not a scientist. Data really isn't his thing.

I don't have a copy of the book so I can't check it myself. Fortunately, Razib Khan, one of Chris Mooney's fellow bloggers on the Discover website, was able to find some of the data [Scientists as “spiritual atheists”].

Let's be clear about one thing. This is not a poll of scientists. It's a poll of American scientists. The title of Ecklund's book, Science vs Religion: What Scientists Really Think, is somewhat misleading.1 Here's two charts from the book.



Hmmm ... none of my assumptions have been undercut. How about yours?

I guess what Chris Mooney means is that some of his assumptions will have to be re-evaluated. It's about time.


1. Unless you're an American. Then you probably believe that all scientists live in the USA.

Is Evolution Guided or Unguided?

Michael Ruse has criticized Alvin Plantinga for being critical of evolution. Plantinga defends himself in a letter published in The Chronicle of Higher Eduaction: Evolution, Shibboleths, and Philosophers.

I want to address one particular point that Plantinga makes because it's relevant to the issues that come up in the accommodationist wars.
"Why," asks Ruse, "does Plantinga feel this way?" Because, he says, "In his view, Darwinism implies that there is and can be no direction in life's history." Still another missed distinction. As far as I can see, God certainly could have used Darwinian processes to create the living world and direct it as he wanted to go; hence evolution as such does not imply that there is no direction in the history of life. What does have that implication is not evolutionary theory itself, but unguided evolution, the idea that neither God nor any other person has taken a hand in guiding, directing or orchestrating the course of evolution. But the scientific theory of evolution, sensibly enough, says nothing one way or the other about divine guidance. It doesn't say that evolution is divinely guided; it also doesn't say that it isn't. Like almost any theist, I reject unguided evolution; but the contemporary scientific theory of evolution just as such—apart from philosophical or theological add-ons—doesn't say that evolution is unguided. Like science in general, it makes no pronouncements on the existence or activity of God.
Plantinga is allying himself with Eugenie Scott and other accommodationists who fiercely defend the idea that science can't address issues such as purpose. In fact, Genie fought hard to remove references to "unsupervised, impersonal, unpredictable and natural process" from a statement on evolution by the National Association of Biology Teachers back in 1995 [NCSE v National Association of Biology Teachers].

I disagree with Plantinga, and with the National Center for Science Education. The idea that evolution might be guided by God is a legitimate question for scientists to address. After all, if it's true then parts of evolutionary theory might have to be revised. I do not accept the claim that scientists must avoid this question because it comes from religion.

When you are thinking like a scientist there's only one possible conclusion. There is no scientific evidence to support the hypothesis that the history of life on Earth was guided by God. Everything we know about the history of life is consistent with an entirely natural process—one that's characterized by chance and contingency. It is perfectly reasonable as a scientist to state this position clearly. This is not stepping outside of the boundaries of science.

Let me explain my position by using an analogy. Imagine the claim that aliens visited the Earth 3.5 billion years ago and seeded our planet with cyanobacteria. After much investigation scientists find no support for such a claim. Is it legitimate for them to conclude that aliens are not responsible for life on Earth? Of course it is. All scientists know that you can't prove a negative but that doesn't mean you can't assign probabilities and behave accordingly.

Philosophers aren't likely to get upset if scientists make statements denying that aliens are responsible for life as we know it. That's because belief in alien visitors isn't one of those kooky ideas that demands special status. However, if scientists make the more general claim that life appears to have evolved by purely natural processes then this gets their dander up. All of a sudden science is threatening religion and this is not allowed. It's "philosophical naturalism" and not "methodological naturalism." It's not science according to Plantinga and many accommodationists, including Michael Ruse. Bollocks, I say.

Scientists call it as they see it. If that upsets the theists then they had better learn to deal with it instead of whining about the science being illegitimate.

Science says that evolution is not divinely guided, based on what we know today.


Teaching the Controversy About Homeopathy

 
I've got a confession to make. I've been posting about homeopathy this week but everything I've said has been negative. You know there must be another side to this "controversy" so in the interest of fairness, here it is. These homeopaths are putting forward the best possible case for taking homeopathic "remedies."1




1. If you pay attention, you'll notice that there's no scientific evidence presented. You already know why.

More Homeopathic Woo: Super-Memory

 
This gets better and better as the week goes on. PZ Myers has discovered a company that markets fragments of DNA to promote good health. You don't actually eat the DNA, instead you drink water that has been exposed to the DNA [More Magic Snake Oil].

The company is called Homeovitality® and one of their products is Super Memory/IQ. I'm showing a picture of the product taken from their website in order to prove to you that it actually exists. This is part of the discussion concerning its scientific/medical efficacy—an important part of science education and social responsibility.

How does it work? Before I explain it to you, you'd better be sitting down. Try and remain calm.

There are two genes in your genome called CRM2 and SNAP-25. CHRM2 encodes a muscarinic receptors and various alleles of this gene have been associated with alcohol dependence and drug dependance, according to the Online Mendelian Inheritance in Man (OMIM) database [CHOLINERGIC RECEPTOR, MUSCARINIC, 2; CHRM2]. SNAP-25 encodes a synaptosomal-associate protein of 25kDa molecular weight. There have been reports that alleles of SNAP-25 are associated with hyperactivity but a separate study did not confirm this association according to OMIN [SYNAPTOSOMAL-ASSOCIATED PROTEIN, 25-KD; SNAP25].

Homeovitality® had some DNA sequences made for each of these genes: a 164 bp fragment in the case of CRM2 and a 144 bp fragment in the case of SNAP-25 [What is Homeovitality®?]. They used these pieces of DNA to make the Super Memory/IQ product.
Homeovitality® products have also been succussed at each dilution stage so they will also help to promote desirable forms of hybrid vigour in a “like promotes like” mode of action involving some of the mechanisms (4) described by Dr. Kratz, (http://kulisz.com/how_does_homeopathy_work.htm).

Homeovitality® products are safe because firstly, they are used at similar dilutions to classical homeopathic disease remedies and secondly, hybrid vigour is a completely natural biological process that has been developed by nature over millions of years to enable all creatures to enjoy “super health” and disease resistance.
"Succussed refers to the practice of forcefully striking the various dilution solutions in order to help "potentize" the effect. "Hybrid vigor" refers to the belief that these DNA sequences—or, more appropriately, the memory of these sequences—will produce heterozygosity in patients and that's a good thing.

Lance Corporal Robert Alexander Hood (1895 - 1917)

Robert Alexander Hood1 was born in 1895 in a small village north-west of Waterloo, Ontario, Canada. He went to France in 1916 when he was only 21 years old. Robert fought with the 73rd Battalion and he was killed in action at Vimy Ridge on this day, April 12, in 1917.

Canadians "celebrate" the battle of Vimy Ridge as a great Canadian victory. It was part of the larger Battle of Arras, which in turn was a diversionary attack in support of the larger Nivelle Offensive carried out by the French Army. About 3,600 young Canadian men were killed during the four day battle and 7,000 more were wounded. This is just a small fraction of the casualties on both sides during World War I.

We need to be very careful not to glorify war while remembering all those young mean and women who died in a war that never should have been fought. I will eventually go to Arras and visit the large memorial erected by the Canadian government (see below) but I will do it in order to reinforce my view that war is folly and the deaths of soldiers like Robert Alexander Hood should never have happened.

There is never any glory in war and it's nothing we should ever be proud of.

The "Science" Behind Homeopathy

 
Are all homeopaths and their supporters complete idiots? Do they all think they're practicing some form of black magic? No, they usually don't think that at all. Many of them honestly believe that there's scientific evidence supporting homeopathy. They actually believe that water can retain some magical properties after it has been exposed to certain chemicals. How is this possible? It's because of "nanobubbles."

Here's John Benneth explaining the "science" behind homeopathy. This is woo of the highest order. Read Orac's take-down at Your Friday Dose of Woo: The physics of homeopathy and "nanocrystalloids". There are no reputable scientists who believe what John Benneth claims. If he's implying that there's scientific support for homeopathy, then what he's saying is not true.

Atheist Barbie

 
Here's the ideal present for all of you with young sons and daughters, or young grandchildren. It's atheist Barbie from Blag Hag.



I'm ordering one today for Zoë ... and two others for Jane and Gordon.

Too Many Gods

 

Me and my Christian friends have a lot in common but I didn't realize how much until I found this site: Gods You Don't Believe In. It lists about 2,800 gods of various sorts. I don't believe in any of them and most Christians reject all but a handful1. That makes about 2,795 gods whose nonexistence we agree on.


1. I'm not sure how to count up the gods of Christianity. If you assume that the big guy, Jesus, and the ghost are all the same person then what about Satan and some of the senior angels like Gabriel and Michael? Do they count as gods? And what about the other gods mentioned in the ten commandments? The god of the Bible says not to worship them because he is jealous but he doesn't deny that they exist. Who are they?

What Is Homeopathy?

 
Homeopathy awareness week is coming up and scientists from all around the world are gearing up to explain why homeopathy doesn't work—that's why it's called "alternative" medicine. It's a part of quack medicine that's not "real" medicine. Real medicine is based on scientific evidence.

Many people don't know what homeopathy is all about. They confuse homeopathy with a host of other forms of non evidence-based medicine like naturopathy and herbalism. That's a big mistake. Homeopathy is a form of treatment where you drink water that supposed to contain the magical imprint of some chemical. The chemical is often quite dangerous but, don't be worried, it's not really present in the treatment you pay for.

Here's the Wikipedia description of homeopathy.
Homeopathy (also spelled homoeopathy or homœopathy) is a form of alternative medicine, first proposed by German physician Samuel Hahnemann in 1796, that attempts to treat patients with heavily diluted preparations. Based on an ipse dixit[1] axiom[2] formulated by Hahnemann which he called the "law of similars", preparations which cause certain symptoms in healthy individuals are given as the treatment for patients exhibiting similar symptoms. Homeopathic remedies are prepared by serial dilution with shaking by forceful striking, which homeopaths term "succussion," after each dilution under the assumption that this increases the effect of the treatment. Homeopaths call this process "potentization". Dilution often continues until none of the original substance remains.
Don't confuse it with anything else. There's absolutely no evidence that homeopathy works. The scientific data, taken as a whole, is conclusive. Be wary of those who believe in homeopathy because their advice on other forms of treatment may not be based on evidence either. Homeopathy is bad enough but it often keeps even worse company.

Should creationism be taught in British classrooms?

 
As most of you know, the citizens of the United Kingdom do not obsess over the separation of church and state and they do not use their constitution to keep creationism out of their schools. That's why the question posed by Michael Reiss in New Statesman is a valid one in that country, "Should creationism be taught in British classrooms?". The answer might surprise many people in other countries.

Why schools and universities should encourage debate on evolution -- and how this could benefit science.

.... When teaching evolution, there is much to be said for allowing students to raise any doubts they have in order to shape and provoke a genuine discussion. The word "genuine" doesn't mean that creationism and intelligent design deserve equal time with evolution. They don't. However, in certain classes, depending on the teacher's comfort with talking about such issues, his or her ability to deal with them, and the make-up of the student body, it can and should be appropriate to address them.

Having said that, I don't pretend to think that this kind of teaching is easy. Some students become very heated; others remain silent even if they disagree profoundly with what is said. But I believe in taking seriously the concerns of students who do not accept the theory of evolution while still introducing them to it. Although it is unlikely that this will help them resolve any conflict they experience between science and their beliefs, good teaching can help students to manage it - and to learn more science.

My hope is simply to enable students to understand the scientific perspective with respect to our origins, but not necessarily to accept it. We can help students to find their science lessons interesting and intellectually challenging without their being a threat. Effective teaching in this area can help students not only learn about the theory of evolution, but also better appreciate the way science is done, the procedures by which scientific knowledge accumulates, the limitations of science and the ways in which scientific knowledge differs from other forms of knowledge.
I agree with this point of view. I think the main arguments for creationism, and against evolution, should be discussed in science class. It's an excellent way of showing what real science is and how it should be practiced.

The problem with ignoring the main criticisms of evolution is that students are going to hear about them from other sources and they won't know what to think about those points of view unless we teach them how to reason. The goal of science education is to teach students how to think, not just fill them with facts. It's our responsibility as teachers to teach critical thinking. One of the best ways to do that is to give them some popular examples to discuss and debate.

Advertising 23andMe

 
Some bloggers are huge fans of genetic testing. They frequently post articles promoting one of the private companies that charge you for doing these tests. ScienceRoll recently posted this video of Anne Wojcicki making a pitch for her company. Wojcicki is one of the co-founders of 23andMe. It's interesting to see how she mixes various rationales for genetic testing with a pitch for 23andMe.

Imagine this was a talk by the CEO of a major pharmaceutical company about the importance of their drugs and why you should buy them. We would probably be more skeptical than we seem to be about Ann Wojcicki. Why is that?

World Homeopathy Awareness Week

 
World Homeopathy Awareness Week takes place next week (April 10-16). This is a week devoted to making people aware of homeopathy and our local Centre for Inquiry and the Committee for Advancement of Scientific Skepticism (CASS) is planning to take full advantage of the opportunity. We'd like everyone to know there's no scientific evidence that supports homeopathic "cures" and, furthermore, the fundamental principle behind homeopathy conflicts with everything we know about modern science.

I urge all bloggers to post something next week in order to let the public know about this scam.

The Canadian Society of Homeopaths also has a number of events planned but I don't think they're talking about the same kind of "awareness."
HOMEOPATHY AND MENTAL WELL-BEING:
BODY AND MIND IN BALANCE

The theme of the 2010 Homeopathy Awareness Month is Homeopathy and Mental Well-being: Body and Mind in Balance. As in previous Awareness celebrations, Registered and Associate members of the Canadian Society of Homeopaths will sponsor events, displays, and special promotions in their communities across Canada.
