Bill Nye’s upcoming debate earns $$ for creationist organizations

January 17, 2014 • 12:43 pm

Here’s yet another reason why Bill Nye shouldn’t be debating creationism with Ken Ham.

Reader Chris called my attention to the fact that the upcoming debate at Kentucky’s Creation Museum is being touted not only by Answers in Genesis, Ham’s organization, but by Kent Hovind’s separate creationist organization Creation Today.  Here’s a screenshot of the email that Chris just got from Hovind’s group (he subscribes for fun):

Bill Nye

And over at the Creation Store at Creation Today, you can preorder the DVD for only $20:

Note: As it says above, “The proceeds for these preorders of DVD’s [sic] and Digital Downloads will go to support Answers in Genesis. . . ” In other words, Nye’s appearance will be giving money to organizations who try to subvert the mission Nye has had all his life: science education, particularly of kids.  And you know what? I don’t even care if Nye mops the floor with Ham. Though that would be great (especially because the DVD promises to be “uncensored”), it doesn’t justify Nye making money to further Ham’s program of lying about science.  That would be, to paraphrase a sign we always see in construction zones: “A temporary victory, a permanent defeat.”

Nye may be great at what he does, but in this case he made a severe misstep, and, at least in this case, he’s not very media-savvy.

Put it this way: would you debate a creationist if the profits from sale of debate-related media all went to further creationism?

As a friend once told me who was about to debate a feminist about gender differences: “You show up, you lose.”

Website post reprinted in The New Republic

January 17, 2014 • 10:27 am

Because someone requested it, I guess I’ll let people know when a post from this site is purchased by and reprinted in The New Republic. My recent post on David Bentley Hart and Oliver Burkeman’s Best Evidence for God has been reprinted at the TNR as “‘The ‘best arguments for God’s existence’ are actually terrible.” As always, I rewrote the website post for the magazine, but not extensively. But I do like the new final sentence of the TNR version.

Meanwhile, Damon Linker, who also praised Hart’s “God-as-ground-of-being” book in a piece in The Week magazine, happens to be a contributing editor at The New Republic, and he’s peeved that two people (Isaac Chotiner and I) went after him in that very magazine. So Linker’s come back with yet another defense of Ground-of-Beingism in The Week,The atheist’s version of God is a straw man.” Hart is one of those nonbelievers who spends all of his time reproving atheists for not going after the most arcane theological arguments. I truly don’t get it. Our job is surely more than mental fencing with academic theologians; it’s also to help rid the world of the bad effects of religion, and those effects are effected by “regular” believers who wouldn’t know a Ground of Being if it bit them in the tuchus.

Nevertheless, I have plenty of ammunition against the charge that most theologians and believers have historically seen God as a G.O.B. rather than as an anthropomorphic disembodied mind in the sky—and one with moral codes for us. My data include statements by famous theologians, some quite Sophisticated, and polls showing that believers overwhelmingly accept a personal God with all the trimmings. But I’m saving that data for my book.

Ohio executes inmate with drug untested for executions; results are both predictable and unjustifiable

January 17, 2014 • 8:06 am

The state of Ohio executed convicted murderer Dennis McGuire yesterday by lethal injection.  Because some the drugs used in the lethal cocktail (usually three) are made overseas, and foreign countries are increasingly unwilling to export drugs used for genuine medical purposes to the U.S., where they can be used to kill people, American states are experimenting with other lethal drugs.  One of those experiments involved McGuire, who was killed with a combination of drugs never before used for executions. The results were predictable: McGuire apparently died a horrible and painful death by suffocation.

As the Guardian reports:

A death row inmate who was executed by the state of Ohio on Thursday with an untried and untested combination of two medical drugs appeared to gasp and snort in a procedure that took an unusually long 25 minutes to kill him.

Dennis McGuire was pronounced dead at 10.53 am at the Southern Ohio Correctional facility in Lucasville. His lawyers had warned ahead of the proceeding that the experimental combination of the sedative midazolam and painkiller hydromorphone might subject him to “air hunger”, an insufficient flow of air into the lungs causing the sensation of suffocation.

. . . A reporter for the Associated Press, which sends a journalist to every execution in the US, wrote that McGuire “appeared to gasp several times during his prolonged execution … McGuire made several loud snorting or snoring sounds during the more than 15 minutes it appeared to take him to die. It was one of the longest executions since Ohio resumed capital punishment in 1999. McGuire’s stomach rose and fell several times as he repeatedly opened and shut his mouth.”

Another eye-witness report from the Columbus Dispatch provided concurring evidence. Dispatch reporter Alan Johnson wrote that four minutes into the procedure, “McGuire started struggling and gasping loudly for air, making snorting and choking sounds which lasted for at least 10 minutes. His chest heaved and his left fist clinched as deep, snorting sounds emanated from his mouth.”

Ohio’s department of corrections originally put the official length of the execution at 15 minutes, but later in the day revised that to 25 minutes.

McGuire’s defence attorney, Allen Bohnert, said that according to reports he had been given from witnesses in the chamber, the prisoner was gasping for breath from about 10.30 am to 10.44 am. At some point, witnesses told Bohnert, McGuire tried to sit up, turned his head toward his family members who were witnessing, and spoke to them. One witness described the scene as “ghastly”.

Midazolam is a benzodiazepine used to control seizures, insomnia,and other conditions requiring anxiolytic drugs.  According to the Guardian, the drug is in short supply in hospitals and will now be in even shorter supply. A typical dose for an execution is 500 mg: 100 times the dose for a patient.  The use of this drug for executions—or any drug that is prescribed for “normal” medical conditions—is opposed by U.S. physicians as well as by foreign governments and companies that refuse to help the U.S. execute criminals by supplying the requisite drugs. As the Guardian notes:

Ohio’s recourse to the midazolam-hydromorphone combination was forced by a shortage of pentobarbital, a drug originally manufactured in Denmark, which has been subjected to strict export licences that prevent sale to US departments of correction. A European-wide boycott, designed to ensure that medical drugs are not used to kill people, has begun to bite across the 32 states that still have the death penalty on their books.

Ohio ran out of pentobarbital in September.

The adoption of midazolam as an alternative drug – not only in Ohio, but also in Florida, one of the most active death penalty states – has led to expressions of anger and disgust by leading physicians in the US. Joel Zivot, the medical director of the cardio-thoracic and vascular intensive care unit at Emory University School of Medicine in Atlanta and an opponent of the use of anesthetics in lethal injections, called the use of midazolam in executions “appalling and unethical”, and said, “The public should be concerned that [the] medicines that are used to help them are being diverted instead to kill people.”

The human rights group Reprieve, which has been a key influence behind the European boycott, has accused Ohio and Florida of stockpiling midazolam to the detriment of medical services.

The U.S. is the only First World country in the West that still practices capital punishment. Wikipedia reports that 58 nations still practice it occasionally, but in 2011 Amnesty International listed only 21 countries known to have executed people. Here’s that list of shame, which puts the U.S. in pretty dire company:

Picture 1

What is the purpose of executing people? The only one I can see is precisely the one that we should not be using: retribution.  “An eye for an eye, a tooth for a tooth,” says the scripture, and many people agree. Indeed, that’s clear from the Guardian report, where the family of the victim wants to see the perpetrator suffer, and the court apparently doesn’t care:

In court proceedings last week, an Ohio state prosecutor said bluntly: “You’re not entitled to a pain-free execution,” and a judge allowed the execution to proceed.

. . . Members of Stewart’s family were present at his execution, and before it they put out a statement that said the manner in which McGuire was put to death was more humane than the brutal way he had murdered Joy.

Well, if that’s the case, why use drugs: why not just garrote the guy slowly? Why even attempt to give him a “humane execution? Why not just subject him to a slow and brutal murder, and why not have him raped with a broomstick in the process?

Don’t get me wrong: McGuire was a horrible person: he raped and murdered 22-year-old Joy Stewart in 1989, and Stewart was 30 weeks into pregnancy, so her fetus also died. The guy certainly deserved to be removed from society, probably for life. In all likelihood he could do it again, and we need to get such people out of our society both for our own protection and to serve as deterrents for others. Without punishment, people would commit more crimes, as Steve Pinker famously pointed out when recounting the wave of crime that followed a 1969 police strike in Montreal.

But execution doesn’t have any salutary effects on society. It serves only to satisfy people’s brutal feelings for retribution. Further, it costs more than imprisonment without parole (my solution for people like McGuire), and there is always the chance that someone executed could be exculpated by later evidence. (This is becoming increasingly frequent in the era of DNA evidence.) You can’t free someone in those circumstances if you’ve already killed them.

Further, if McGuire, as I believe, had no choice in his actions, and could not have refrained from killing Stewart, does he really deserve a painful execution for that, and to lose his life? Aren’t there better ways of dealing with people whose backgrounds have driven them to do things about which they had no choice? The motive of retribution, unlike that of deterrence, sequestration, and rehabilitation, is based on the supposition that the criminal had a choice in what he did.  If you’re a determinist, or even a compatibilist, you know that’s not true. The list of countries above includes many that are religious, and that’s no surprise, for Abrahamic religions are based on the supposition of libertarian free will, and that presumption that you have a choice about murdering is a natural partner with retributive capital punishment.

If McGuire had been mentally ill, he would not have been killed. In that way the law recognizes that people driven by forces they can’t control shouldn’t be punished by execution. They are usually put in secure mental facilities, where attempts at “rehabilitation” are made. Those often fail, but that’s because serious studies on how to rehabilitate people are rarely done.

But McGuire’s actions are also the result of his physical constitution and his environment: things he couldn’t control either. He had no choice to refrain from a horrible act.  What is the justification for killing him but not those who “don’t know the difference between right and wrong” or “who aren’t competent to think about the consequences of their act”? None of those people could have behaved other than the way they did. Further, we can’t even use the excuse of deterrence to execute people, for the death penalty is not a reliable deterrent to capital crimes (see here, here, here, here and here), and is opposed by most law-enforcement organizations in the U.S. And even if there were marginal effects on deterrence, do those outweigh the possible execution of innocent people?

The death penalty is one of the consequences of not thinking seriously about free will.  Most rational societies have abandoned executions as a brutal and useless exercise.  The United States should, too.  So long as we kill people like McGuire, don’t really care much whether they die painfully or not, and think that they deserve what they get because they chose the wrong action, we should have no place at the table of civilized countries.

Exquisite behavioural mimicry: fly acts like a wasp

January 17, 2014 • 6:15 am

by Matthew Cobb

This video, posted by Chris Hassall, shows a hoverfly – NOT a wasp – sitting on a leaf.

You can tell it’s a fly because it’s only got one pair of wings (it’s a DI-pteran), and those wings aren’t folded longways when at rest. Plus both the eyes and the antennae are fly-like, not wasp-like (I guess those antennae also gave rise to its species name – Spilomyia longicornis [‘long horns’]). Those colours and morphology would be enough to ward me off if I were a predator. It sure looks like a wasp.

What’s intriguing is that this species has gone a step further – it not only looks like a wasp, it behaves like a wasp. Look at the way it moves its legs and wings. That’s not what flies normally do – it looks very wasp-like indeed.

In the information under the video, Chris writes:

Behavioural mimicry occurs when an animal acts like another animal in order to deceive a third animal. In this video (taken by Dr Henri Goulet), you can see the fly wagging its wings in a manner characteristic of wasps, repeatedly tapping its abdomen against the flower (although flies cannot sting), and holding its dark forelegs in front of its head to mimic the longer antennae of wasps.

Research conducted at Carleton University, Agriculture and Agri-Food Canada and the University of Leeds has shown that only those hover flies that look most like wasps exhibit these kinds of behaviours.

Here’s the abstract of that research; the full paper will shortly be published in The American Naturalist:

Palatable (Batesian) mimics of unprofitable models could use behavioral mimicry to compensate for the ease with which they can be visually discriminated or to augment an already close morphological resemblance. We evaluated these contrasting predictions by assaying the behavior of 57 field-caught species of mimetic hover flies (Diptera: Syrphidae) and quantifying their morphological similarity to a range of potential hymenopteran models. A purpose-built phylogeny for the hover flies was used to control for potential lack of independence due to shared evolutionary history. Those hover fly species that engage in behavioral mimicry (mock stinging, leg waving, wing wagging) were all large wasp mimics within the genera Spilomyia and Temnostoma. While the behavioral mimics assayed were good morphological mimics, not all good mimics were behavioral mimics. Therefore, while the behaviors may have evolved to augment good morphological mimicry, they do not advantage all good mimics.

One question is why it’s the larger flies that engage in behavioural mimicry. Maybe predators are smarter than we think, and can see in the larger flies that the wings and eyes and antennae indicate this could be a tasty morsel, so those flies have ended up going the extra mile and evolved behaviours that would convince even the most dubious predators that this is NOT a fly (which of course it is), but instead a wasp.

Friday: Hili dialogue

January 17, 2014 • 3:39 am
Hili asks about New vs. Old Atheism (I suspect by “Old Atheists” Hili means folks like Robert Ingersoll, Bertrand Russell, and H. L. Mencken.)
Hili: What is the difference between a New Atheist and the Old Atheists of yore?
A:  New Atheists may be old or young, but they haven’t lost their capacity to learn, whereas a contemporary atheist who admires only the dead Old Atheists and bashes the new ones is unable to learn.

1517561_10202547423274135_1185627595_nIn Polish:
Hili: Czym się różni Nowy Ateista od starego ateisty?
Ja: Nowy Ateista może być stary, ale nie stracił zdolności uczenia się, natomiast stary ateista zgoła odwrotnie.

How to treat a cat

January 16, 2014 • 3:43 pm

Reader Emma sends greetings from across two ponds, as well as a picture of her cat Sagan and a note:

I recently moved from Australia to Denmark to do a postdoc, and had to leave my lovely cat in the care of my parents. It has taken a long time to adjust to a catless existence and I still haven’t quite recovered. However, the pictures of you napping with Hili made me smile, and feel a bit less homesick.

In case you are also missing Hili, I am sending a photo of my cat, Sagan. It is 43 degrees (C) back home today, and my mum sent me this photo of the cat cooling off in front of every fan in the house. It looks like Sagan is being treated with all due deference!

Free will: three easy pieces

January 16, 2014 • 2:03 pm

1. Here’s a cartoon from reader Pliny the in Between’s website, “Pictoral Theology. . . and other Stuff.” This one’s called “I had no choice but to post.” (Click to enlarge.)

Untitled.001

2.  Here are two frequently asked questions about free will (I should write a “FAQ” about this because the same objections arise repeatedly).

a.  Doesn’t determinism preclude you from ever changing your mind?  Answer: No, for changing your mind can occur via deterministic influences of the environment on your brain.  Watching a lifelong smoker whom you love die of cancer, for example, may be a powerful impetus for you to quit smoking. Humans are evolved to reason (think of our brain as a computer, even though, dear readers, I am perfectly aware of the differences between brains and human-constructed computers), and we can process inputs into outputs which are generally adaptive.  So you can change your output in light of different inputs. What I maintain is that you cannot by your own conscious will alone change your mind, for that presumes a “ghost you” that can affect how your brain processes information. Nor can you ever be able to truly choose either of two alternatives at a given moment in time.

b. Doesn’t determinism preclude us from reasoning about problems and arriving at conclusions? Answer: No, for the same reason given above.  Our brains, as Daniel Dennett has told us repeatedly in his books on compatibilism (I disagree with his compatibilism but agree with much of the other stuff in his “pro-free-will” books) are very complex meat computers that have evolved to process a variety of inputs before giving an output—a decision.  And those brains have evolved to arrive, in general, at outputs that are good for our well being: “good” decisions.  Some people have better onboard computers than others, and those people are called “smarter” or “deeper thinkers”, although they are that way through no effort of their own. So, yes, you can reason and arrive at rational conclusions, which is exactly what computers do when they arrive at outputs after absorbing a lot of information (think chess-playing computers).

I’ve found that a lot of objections to free will that aren’t very cogent can be overcome by simply thinking of our brains as complex computation machines, evolved to help their possessor’s well-being (i.e. reproduction or the proxies of reproduction).

3. Here is a Baby Hili dialogue in which she ponders free will (these “Baby Hili” dialogues don’t appear on this website, but can be found in the Hili Dialogues Tumblr Site curated by Miranda Hale (go to “archive” and look back, for example, from August through December of 2012; Hili was born in the spring or early summer of that year).  And don’t forget that all the Hilis, young and old, are posted on Twitter, where you can follow the Queen’s feed. Hili is of course concerned that not enough people are following her.

This dialogue shows that Hili was already reading my website as a youngster:

I can tell you with near-certainty which of those two brands of milk Hili would elect if given a choice.  And that’s based only on my crude observation of her behavior, not on feline brain scans.

Whaddya gonna do?

January 16, 2014 • 12:26 pm

There are some types of creationist ignorance that can’t be overcome because of sheer laziness of the benighted. Reader Barry sent me one example from his Twi**er feed:

Jerry CoyneI make the same suggestion all the time to creationists who pretend to want information but really want to save my soul. And not one of them has ever gotten back to me saying that they read my book.

Or, if I wanted to be charitable, I could point out that, according to a HuffPo/YouGov poll in 2013, 28% of Americans hadn’t read a single book over the past year, while 42% had not read a nonfiction book.  That’s from a poll of 1000 people, and I suspect those numbers are underestimates.
