The last homework assignment

October 7, 2013 • 3:33 am

Now I suppose this might be a fake, but I’m posting it under the assumption that it’s real. It’s the last homework assignment of a dying Japanese teacher, who apparently passed away soon after he wrote this on the board:

(from RocketNews24 via Twitter)

last-hw01

And the translation (Japanese-speaking readers please verify):

Final homework assignment
No due date

Please be happy.

By the time you are ready to turn in this assignment, I will probably be in heaven.
Don’t rush your report. Feel free to take your time.
But someday, please turn to me and say “I did it. I’ve become happy.”
I’ll be waiting.

This is also posted on a Japanese site, which claims that the teacher died of stomach cancer. That was the same disease that afflicted the lead character (a Japanese bureaucrat) of the greatest foreign non-U.S. film ever made, Ikiru.  He, too, found a way to be happy.

It’s a tear-jerker for sure.  But Professor Ceiling Cat concurs: please be happy. We’re on this planet but a short time, so enjoy the beautiful day (even if its raining), have some nice noms, read a good book, and pet your cat. (You don’t have a cat? Adopt one!) Oh, and watch Ikiru, which is free online here.

Monday: Hili Dialogue

Hili, who has apparently read Jared Diamond, is always on the lookout for interesting noms:

Hili: When a third chimpanzee opens the refrigerator a cat goes to the kitchen.
A: But your three bowls are full.
Hili: But you might take out something more interesting.

In Polish:

Hili: Kiedy trzeci szympans otwiera lodówkę, kot idzie do kuchni.
JHa: Przecież masz swoje trzy pełne miseczki.
Hili: Ale może wyjmiesz coś ciekawszego.

The Discovery Institute continues its whining about Ball State’s courses

October 6, 2013 • 1:05 pm

UPDATE: Check out the reader comments on the DI letter. Every one supports evolution and makes fun of the DI’s disingenuous claims. I’m proud of Muncie!

______________

The fun continues! Today’s Muncie Star-Press publishes a letter from the Discovery Institute (DI), which has recently threatened legal action against Ball State University (BSU) for “censoring” intelligent design (ID) when it was presented as real science in a science course.

The DI’s ire, as you may recall, was incited by an investigation BSU conducted of a course taught by Dr. Eric Hedin—a science course that used ID and other theistic material but no material critical of those views, and a course proselytized the view that the cosmos reflects the glory of God. That investigation resulted in the deep-sixing of Hedin’s course and a strong statement by BSU President Jo Ann Gora that intelligent design would not be taught as science in her university.

Here’s the DI’s letter printed in today’s paper:

JOHN G. WEST

Vice President, Discovery Institute, Seattle

The article, “BSU reviewing alleged ‘atheism’ class” (Oct. 1), falsely claims that Discovery Institute is a “pro-creationism … think tank.” Creationism is commonly understood as a belief that the earth was created by God a few thousand years ago during seven 24-hour days based on a literal reading of the Bible. Discovery Institute does not advocate creationism, and we oppose its introduction in public schools.

Discovery Institute does support scientists who think there is evidence of intelligent design in nature. Intelligent design is not based on an interpretation of the Bible, but on the clear evidence of nature itself, such as the fine-tuning of the laws of physics, the digital information encoded in DNA, and the thousands of exquisitely-functional molecular machines operating inside our cells. For more about what proponents of intelligent design actually believe, I encourage readers to visit http://www.intelligentdesign.org.

Critics of intelligent design who mislabel it “creationism” are trying to avoid genuine debate by stereotyping intelligent design proponents rather than engaging their actual arguments. This tactic is unbefitting a free and open society.

So is Ball State University’s new speech code that prohibits faculty from expressing support for intelligent design in the classroom, but apparently does not restrict them from attacking intelligent design.

Censoring one side of a debate is not a good way to find the truth. As Darwin himself advised: “A fair result can be obtained only by fully stating and balancing the facts and arguments on both sides of each question.”

How much fail can they cram into such a letter? Of course Intelligent design is creationism; it’s just creationism on a micro scale. It demands the concept of a creator who makes adaptive leaps that evolution can’t. (Of course IDers affirm that creator could be a space alien rather than God, but we all know that’s a lie.) Many IDers accept microevolution but not macroevolution (the latter is the bailiwick of the “designer”), and Michael Behe accepts the idea of common ancestry while, bizarrely, rejecting the notion of macroevolution. The Wedge Document clearly shows that intelligent design is in fact based on an interpretation of the Bible.

If the DI does not advocate creationism, or favor its introduction into public schools, then they must reject intelligent design as well.

Second, there is no “genuine debate”, at least in a scientific sense, about ID.  Every example offered as evidence for intelligent design, such as blood clotting and the bacterial flagellum, can plausibly be explained as a product of materialistic evolution. There is thus no need to resort to supernaturalism simply because science supposedly is baffled by the evolution of such traits.  The real “debate” is between those who wish to foist religion on schoolchildren and those who want real science taught instead.

Finally, you have to discuss intelligent design when you show why it’s wrong.  When I tell students why evolution is a better explanation for the facts of biology than is creationism, for instance, I have to explain what kind of creationism I have in mind.  That’s exactly what Darwin did when making the case for evolution in The Origin.

What is not scientific is to make up reasons why ID is a viable explanation, and better than a naturalistic one.  A speech code need not mandate that, if you mention ID and creationism, you must show support for it as well. The case for ID has been made, and it’s failed. Discussing the issue can’t, therefore, be balanced in the way the DI wants, for the scales of evidence weigh heavily on the side of naturalism.  It’s like trying to make a balanced case for a flat earth, the truth of astrology, or religiously-based claims like Noah’s flood or the historicity of Adam and Eve.

I’m still waiting for the DI’s legal challenge to Ball State. Bring it on, Dr. West! I’d like nothing better, but I’m betting no legal papers will ever be served.

Pileated woodpecker (and gratis cat)

October 6, 2013 • 10:11 am

Reader daveau, on a trip to Door County with his family (including les chats) managed to come across America’s largest woodpecker, the Pileated Woodpecker (Dryocopus pileatus), whose amazing behaviors I describe in WEIT.  He sends us a description, a lovely photo, a video of the beast pecking away, and, of course, the obligatory shot of his shorthair Merlyn:

Who could resist naming him Woodrow? Here’s a gorgeous Pileated Woodpecker that we saw this week in Door County, Wisconsin. The male has a crest that goes all the way down to his bill, and has a splash of red on his cheeks. We were pulling into a new supper club on the Lake Michigan side of the peninsula, when I saw him fly to a tree for his own dinner. A 30-inch wingspan will get your attention. We parked the car, and went back to take a look. We spent 10-15 minutes up close, but only had an iPhone to take pictures with. Wildlife photography rule number 1: always bring a camera.

I was convinced that this was either his territory, or maybe just a fantastic feeding ground. Either way, we expected that he would hang around. Anyway, we came back the next evening armed with a camera, but didn’t spot him. However, on Tuesday, we were in the area again and decided to check out the grove. The results are what you see. We spent at least a half hour watching him from around 12 feet away. The video is really two videos, one taken by the spousal unit, Debra, and the other by me, each followed by a slow motion version. In the original, which is probably higher resolution, in slow motion, I can see his tongue shooting out like an anteater’s, immediately following each peck, and slurping up whatever grubs/insects he was after. Fascinating.

I also include a picture of Door County’s most fearsome denizen: Merlyn.

Nobel Predictions 2013: Hall, Rosbash and Young for biological clocks

October 6, 2013 • 8:21 am

by Matthew Cobb

It’s that time of year again. The next week will see pictures of cheerful looking middle-aged (or older) men (they will be mainly men) holding bottles of champagne and explaining work they did years ago which has just won them fame and fortune and a Nobel Prize. Some of them will have beards. Many of them will be from the USA. This much history tells us. What is more difficult to predict is WHO will win which prize, with the exception of physics which will presumably go to Higgs for his boson (pronounced bo-zon).

First up (I think) is Physiology or Medicine, which is announced tomorrow. Here is my prediction: Jeff Hall, Michael Rosbash and Mike Young for their work on discovering the mechanism by which ‘clock’ genes work. They have won a series of major prizes over the last 18 months, and it seems inevitable that the Nobel Committee will soon be honouring them, so why not this year?

These clock genes were first found in the insect Jerry and I study: Drosophila melanogaster. In 1971 Ron Konopka, working with the late Seymour Benzer, announced the discovery of a gene, which they called period, which changed the fly’s ‘circadian’ rhythm. Furthermore, Konopka and Benzer had made three mutants in this gene – one mutation made the clock tick slowly (per long) so the flies were on a 29 hour cycle, one made  the clock tick fast (per short) so the flies were on a short cycle (19 hours ) and another was a null mutation in which the clock was broken and the flies had no rhythm.

Through the 1980s and 90s, Hall, Rosbash and Young worked out how the fly biological clock works, and it soon became apparent that this is not only a clock in Drosophila – many of the key elements of the fly’s clock also function in other animals, including humans.

To get a better idea of what the research entailed, here is a video in two parts explaining the research, which was made to mark the award of the Shaw Prize to the trio a few months ago. As you’ll see from the first video, Jeff Hall is an interesting character. Jeff is now retired, but even when he was active he was also a non-professional historian of the American Civil War, publishing a book about the battle of Gettysburg. He also has a reputation for being somewhat unpredictable; his Stockholm acceptance speech would no doubt be a gem.

Chip in below with your predictions for this Nobel and the others.

Does reading literary fiction make us empathic?

October 6, 2013 • 6:00 am

UPDATE:  I had forgotten that Steve Pinker talked about the link between reading fiction and becoming empathic in his book The Better Angels of our Nature (one commenter mentioned this below), but hey, the book is 800 pages long and I can’t remember everything! Pinker mentions his discussion, and his agreement that the Science paper is dicey, in a tw**t today:

Picture 2

______________

I don’t think literature is a “way of knowing,” at least a nonscientific way to find out truths about the cosmos and humanity, but it may be a “way of feeling.” That is—as suggested many times before—literature may hone our empathy, making us more keenly attuned to the feelings of other people. Or it may make us realize some things about ourselves, which I suppose you could construe as a “way of knowing” in a restricted sense.

But does literature really do that? According to two social psychologists at the New School for Social Research, the answer is “yes.” The new paper in Science by David Comer Kidd and Emanuele Castano on this topic has gotten a lot of press, including a big piece in the New York Times that’s very breathless, and largely uncritical, about the results.

The NYT piece, by Pam Bellock, starts off implying that reading literary fiction has such long-term effects on your ability to empathize with others that it can even help you get lucky:

Say you are getting ready for a blind date or a job interview. What should you do? Besides shower and shave, of course, it turns out you should read — but not just anything. Something by Chekhov or Alice Munro will help you navigate new social territory better than a potboiler by Danielle Steel.

That is the conclusion of a study published Thursday in Science.

Science is, of course, one of the world’s most prestigious scientific journals.

But that’s bad reporting, because the new study suggests nothing of the sort.  What it does suggest is this: after some literary fiction, compared to no reading, reading nonfiction, or reading “nonliterary fiction,” subjects generally score better on tests that allow them to “detect and understand others’ emotions,” which Kidd and Castano see the affective part of the Theory of Mind (our ability to enter into the subjective states of others).  The effects are measured immediately, after the subjects read passages from different works, and there’s no demonstration that these effects last longer than whatever time transpired between the reading and the psychological test—presumably an hour or so.

There were five tests each, say the authors, showing a significant effect in the expected direction (literary fiction makes you more able to read other’s emotions than does reading nonliterary fiction, nonfiction, or nothing at all). But in many cases the significance levels are marginal—p values around 0.04, when the cutoff boundary is 0.05—and one value of 0.08 (sometimes psychologists use higher cutoffs like p < 0.01). Those values represent the chance of getting the observed result given that there really is no effect on empathy of reading literary stuff. In all tests the authors also assessed each reader’s previous exposure to fiction using an “Author Recognition Test” (ART), which presumably gives you an idea of how much fiction reading the subject had done in his/her earlier life.

I won’t go into the types of readings used; you can read the original paper (judicious inquiry might net you a copy), or read the NYT summary.  There were five types of tests, with Test 1 comparing those who read literary fiction versus nonfiction.  In that case, the ability to read others was assessed by the a “Reading the Mind in the Eyes” test, whereby subjects looked at pictures of faces and were asked to judge what emotions those faces were expressing. There was a significant effect of reading literary fiction in the expected direction (more accurate reading of faces), but, significantly, there was an even larger effect of the subject’s ART. The ART effect was a general finding in the study: previous recognition of authors led to better cognitive performance, often with high significance (p < 0.001).

While one can argue that the ART effect simply reflects the longer-term results of reading fiction beyond that seen in this paper’s short-term tests, it could also show the reverse causation: those with high ART scores read fiction because they are a priori more empathic and want to explore the feelings of others in literature. But the ART test itself does not distinguish between recognizing “literary” authors like Jane Austen or “nonliterary” authors like Dan Brown. That’s important because the authors’ results show that literary fiction creates better affective scores than reading nonliterary fiction.

As a colleague noted after reading the study, looking at faces is a weird way of assessing any empathy acquired by reading:

It’s suspicious that reading fiction improves the ability to read emotion from the eyes, since that’s exactly the aspect of theory-of-mind performance for which fiction ought to provide no help whatsoever.

The colleague suggested that reading literary fiction may simply require more concentration than the other types of readings, and that paying greater attention may carry over to the psychological tests.

The other four experiments used different tests, but three of them also involved looking at faces—as well as non-visual assessments of affective behavior.  These other tests also incorporated a no-reading control as well as reading nonfiction. In all cases literary fiction improved affective Theory of Mind behavior more than reading other stuff or not reading at all.

The general results, as the authors note, supported their hypothesis:

The results of five experiments support our hypothesis that reading literary fiction enhances ToM [Theory of Mind]. Existing explanations focused on the content of fiction cannot account for these results. First, the texts we used varied widely in subject matter. Second, it is unlikely that people learned much more about others by reading any of the short texts. Third, the effects were specific to literary fiction. We propose that by prompt-ing readers to take an active writerly role to form representations of characters’ subjective states, literary fiction recruits ToM. The evidence we report here is consistent with this view, but we see these findings as preliminary and much research is needed.

. . . our findings demonstrate the short-term effects of reading lit-erary fiction. However, taken together, the relation between the Author Recognition Test and ToM performance and the finding that it is specifi-cally literary fiction that facilitates ToM processes suggest that reading literary fiction may lead to stable improvements in ToM. Since the Au-thor Recognition Test does not distinguish between exposure to literary and popular fiction, additional research with refined methods is neces-sary to test this important hypothesis.

While the NYT report on this paper mentions one of my worries: that the psychological results of reading literary fiction were measured just minutes after reading the passage, it doesn’t mention the even larger results of the Author Awareness Test, which either might or might not support the authors’ theory. The TImes piece is simply worshipful, incorporating praise from evolutionary psychologists, English professors, and, of course, a “literary” author, Louise Erdrich, who said this:

“This is why I love science,” Louise Erdrich, whose novel “The Round House” was used in one of the experiments, wrote in an e-mail. The researchers, she said, “found a way to prove true the intangible benefits of literary fiction.”

Yes, we do love science when it “proves” what we want to believe, don’t we? But surely the the Times reporter could have dug deeply enough to find some criticism.  After all, I’m reporting the views of two critics in this piece alone.

And indeed, in their last paragraph the authors seem to say that their results support the use of literature in existing programs designed to “promote social welfare”:

Literature has been deployed in programs intended to promote social welfare, such as those intended to promote empathy among doctors and life skills among prisoners. Literature is, of course, also a required subject throughout secondary education in the United States, but reformers have questioned its importance: A new set of education stand-ards that has been adopted by 46 U.S. states (the Common Core State Standards) controversially calls for less emphasis on fiction in secondary education. Debates over the social value of types of fiction and the arts more broadly are important, and it seems critical to supplement them with empirical research. These results show that reading literary fiction may hone adults’ ToM, a complex and critical social capacity.

As my colleague said dryly about that, “Anything that flatters highbrows (and which has an obvious political agenda, which they reveal in the last paragraph) should indeed be looked at with suspicion.”  I agree.  While the paper is suggestive, it’s nowhere near as conclusive as the Times reports, and I’m surprised it was published in Science.  It needs replication with more types of controls, tests that don’t involve looking at faces, and, most important, more replication.

Now don’t get me wrong. I do think that reading literary fiction makes us more empathic toward our fellow humans.  One example is The Death of Ivan Ilych by Tolstoy, one of my favorite stories.  That novella, though psychologically wrenching, makes you ponder not only the transience and meaning of life, but, as I was told by critic James Wood, was once used in medical schools to teach students what it felt like to die.  The authors of that Science paper may indeed be right, but I’d feel better if my subjective feeling was supported by stronger research.

The little lion who couldn’t roar

October 5, 2013 • 2:08 pm

But he’s trying! This white lion cub, just born at a zoo in Serbia, is trying so hard to roar like the big guys. But all he can do is make a noise like a sheep.

As PuffHo notes:

Nevertheless, her debut at the Belgrade Zoo in Serbia on Thursday could not have been any cuter. The unnamed cub was born last week, according to The Associated Press. She is the daughter of a lioness called Masha and weighs in at just 2.8 pounds.

White lions, which are found in some reserves in South Africa (I’ve written about them before; go here to see the cool pictures), are not albinos but show leucism, a genetic trait due to a single mutation. Here’s Wikipedia’s explanation:

They have pigment visible in the eyes (which may be the normal hazel or golden color, blue-gray, or green-gray), paw pads and lips. Blue-eyed white lions exist and may be selectively bred. The leucistic trait is due to a recessive mutation in the gene for Tyrosinase (TYR), an enzyme responsible for the production of melanins. More severe mutations in the same gene have been found to cause albinism in many species, while another less severe mutation in the same gene is responsible for the Chinchilla coloring trait seen in several mammals. Reduced pigment production decreases the deposition of pigment along the hair shaft, restricting it to the tips. The less pigment there is along the hair shaft, the paler the lion. As a result, “white” lions range from blonde to near-white. The males have pale manes and tail tips instead of the usual dark tawny or black.

They’re magnificent beasts, and, as I’ve written before, don’t seem to suffer much in comparison to normally-colored lions, although one would think that they’d suffer a disadvantage in their nocturnal hunting success. A small disadvantage, however (say, a 3% deficit in reproduction), could be evolutionarily significant but not measurable without huge samples, which we don’t have.
