Monday: Hili dialogue (and Leon lagniappe)

September 19, 2016 • 6:30 am

It’s Monday, September 19 in Chicago, and it’s National Butterscotch Pudding Day! The chances are slim that any of us will have this comestible today, as I haven’t seen it on any menus in decades. But I’m sure you can buy the Jell-o brand in the store. It is good.

Who remembers this?

On this day in 1881, President James Garfield died of his wounds after an assassin shot him on July 2 (he almost certainly died of infection); Garfield, who had assumed the Presidency only that year, was succeeded by Chester Arthur. On Sept. 19, 1959, Nikita Krushchev was prohibited from visiting Disneyland due to security issues; he was mad. And, on this day 1991, Ötzi the Iceman, the preserved body of a 5000-year-old Copper Age man, was discovered by two tourists on the border between Austria and Italy. It remains the oldest “mummy” found in Europe.

Notables born on this day include Duke Snider (1926), Adam “Batman” West (1928), Cass Elliot (1944; went to my high school), Jeremy Irons (1948), and Twiggy (née Lesley Hornby, born 1949 and therefore almost my age). Those who died on this day include, beside James Garfield, mountaineer Lionel Terray (1965), Hermes Pan (1990), Skeeter Davis (2004), and Eddie Adams (also 2004). Meanwhile in Dobrzyn, Hili, the spoiled cat, is slaking her thirst with some whole milk:

A: Why are you so thirsty?
Hili: Some mice are too salty.
p1040874
 In Polish:
Ja: Co ci się tak pić chce?
Hili: Niektóre myszki są przesolone.

And in the fields around his Forever-Home-to-Be, Leon exculpates himself:

Leon: It wasn’t me, it was beavers!

Meet Samson: a big 28-pound Maine Coon cat, and not fat!

September 18, 2016 • 2:30 pm

If you remember the movie “Boogie Nights”, you’ll know this paraphrase: “This is a giant cat!” Yes, it’s Samson, a big 28-pound Maine Coon cat, said to be “the biggest cat in New York,” which isn’t really a world-class distinction. Still, Samson is a magnificent animal; as I always say, a bigger cat—so long as it’s not fat—is a better cat.

Sadly, there’s too much in the video about how its staff tries to make Samson an Internet sensation; but just ignore that and look at Samson.

Dalai Lama promulgates the “no true Muslim” fallacy

September 18, 2016 • 1:37 pm

Here are a few of the Dalai Lama’s remarks to the Committee of Foreign Affairs of the European Parliament in Strasbourg, which he visited on Thursday. As you see, he claims that any religious person, not just Muslims, cannot be a “true believer” if they commit terrorism. This, of course, is a meaningless and tautological statement, like saying that no true cat would eat cucumbers.

Among religious leaders, Tenzin Gyatso is among the least offensive and most amiable. But he’s not immune to mouthing pious inanities like the above. Try telling the members of ISIS that they’re “not genuine Muslims”.

Gyatso is a long way from Abu Bakr al-Baghdadi, but one more thing bothers me about him. He’s characterized as science friendly, and he’s even said this:

“If scientific analysis were conclusively to demonstrate certain claims in Buddhism to be false, then we must accept the findings of science and abandon those claims.”\

Yet, as far as I know, he believes not only in karma, which is a supernatural concept, but in reincarnation, part of the karma trope. Now we can’t really prove these “false”, but the evidence is against them, since if there were reincarnation the population of animals on the planet would be constant (unless, of course, microbes are silently disappearing as they wend their way to mammals).  But you can’t claim that the Dalai Lama is fully down with naturalism.

 

A New York Times debate on trigger warnings

September 18, 2016 • 12:00 pm

Five days ago, the New York Times had one of its occasional debates in which several people write short pieces on a controversial issue. This one was called “Do Trigger Warnings Work?“, and there were two people on the “yes” side and one on the “no” side, so it’s not balanced. Nor are there data adduced (though one person mentions the existence of data), so at least the “yes” votes, are based purely on people’s “lived experience.” The whole debate was inspired by the letter sent by the Dean of my university to incoming first-year students, saying that the University of Chicago did not mandate trigger warnings, intellectual safe spaces, nor the disinviting of controversial speakers.

Before I summarize the arguments, I’ll once again give my own take on trigger warnings. First, I don’t think they should be mandatory at any university; decisions about whether or how to implement them should be left to the faculty.

How would I use them? Well, if I were presenting something that I thought was generally disturbing, like pictures of dead bodies, or wounds, or harrowing testimony (being an evolutionist, I never have to do this), I’d warn students in class on the day of presentation. I would not, however, issue trigger warnings for things like food and drink, violence, or things that people don’t find generally upsetting (see the mention of The Iliad below). Rather, I’d announce at the beginning of class that if students find some subjects disturbing, they should come to me in private in advance to let me know, and I would try to warn that student (privately) beforehand.

What I would not do, however, which at least one of the pro-trigger-warning people suggest, is to let these students have alternative assignments that are not as “triggering.” That is, I would not change the material or my syllabus, either for the class or for individual students. If a student has a problem, I would warn them privately but they’d still be responsible for facing the material. This is based on the finding that exposure to “triggering” material is the only way to surmount one’s phobia. Of course,  I am not a therapist and so students who are triggered by things they encounter frequently would be well advised, as one debater notes, to seek treatment.

Actually, you can read the three pieces yourself, but I’ll comment briefly:

It just seems like the right thing to do by Elana Newman, the R. M. McFarlin professor of psychology at the University of Tulsa, a research director at the Dart Center for Journalism and Trauma, and the co-director of the Tulsa Institute of Trauma, Adversity and Injustice.

Newman’s piece is actually sensible. She has no evidence that trigger warnings work, but says that several of her students have been grateful for warnings, as it allows them to confer with their therapist in advance. This of course means you have to put out the warning before the class, and given the list of things that some students find triggering, that’s impractical as a general tactic. But she also notes this:

Can trigger warnings be harmful? Although a student has never said this to me, I can imagine that explicit cautions may promote anxiety or expectations for an unpleasant emotional experience. Several graduates have told me that while my intentions were noble, the warnings were useless. They simply had no tools to understand their experiences at that time. Some said they felt nauseous, panicked, had flashbacks or engaged in avoidance activities after class that they did not understand. So the warnings were at best inert for them. Others told me they understood their responses to these reminders but they could not control them nor were they interested in working on them at that time. Interestingly, not one student ever held me responsible for those reactions.

Trust me, trigger warnings are helpful” by Sofie Karasek, the director of education and co-founder of End Rape On Campus.

Karasek is the most SJW-ish of the three debaters. She also describes herself as a “sexual assault survivor,” which surely influences her take. (I can’t find any evidence that Karasek, who is only 22, actually teaches students.) While adducing no evidence for the efficacy of trigger warnings save one anecdote, she recommends allowing those who might be triggered to study alternative material, a stand I don’t agree with (again, they should be in therapy):

It is not that difficult issues should not be taught — it is that they should be taught with nuance. Allowing a military veteran to skip a screening of Pearl Harbor or to opt for a less graphic version of a chapter about the Vietnam War is not succumbing to “political correctness” or interfering with learning; it is treating people with basic decency and respect.

You could also say that it is coddling students who should have exposure therapy. And what do you do with a book like The Iliad, which is full of violence and, indeed, has been subject to trigger warnings for “graphic violence,” “sexual violence,” and “suicide”? What alternative work of literature can you give them? None that I can think of. (The Bible, of course, is larded with violence and sex; should schools of theology issue trigger warnings for scripture?) In the end, Karasek goes off on a Regressive Leftist detour that doesn’t seem that relevant, and also is heavily weighted with identity politics and the promotion of her ideological agenda in class:

We are in a period of revitalized storytelling activism, from Black Lives Matter to#SayHerName. These stories are profoundly important because they open our culture’s eyes to systemic injustices that have long been ignored. Thoughtfulfacilitation from professors is crucial in these heavy conversations. For instance, asking, “Does anyone have anything to add, or a different opinion?” in response to a classmate characterizing all veterans as Islamophobes or all rape victims as liars encourages students to question sweeping and harmful generalizations.

Individuals from communities that are disproportionately affected by societal injustices are sometimes hesitant to participate. For instance, though I am open about being a sexual assault survivor, many people are not, in part because of the stigma associated with it. And frankly, while sometimes I might be willing to engage with someone who doesn’t believe that rape is “a real problem,” many times, I would rather preserve my mental health. In this situation, I would be more likely to participate if I saw my professor debunk myths about sexual violence with statistics and evidence-based research. When we silence marginalized voices by refusing to create a respectful atmosphere, we damage the educational experience for all of our students.

If you need a trigger warning, you need P.T.S.D. treatmentby Richard J. McNally, a professor of psychology and the director of clinical training in the department of psychology at Harvard University. He is the author of “Remembering Trauma.”

McNally, who probably has the most knowledge about this issue from a psychological standpoint, draws a distinction between “trauma” and full-blown “P.T.S.D” (post-traumatic stress disorder), which, I think is recognized as a proper distinction by psychologists and psychiatrists. His solution is not to give trigger warnings to either group, because—at least for P.T.S.D. sufferers—they’re counterproductive. (That, of course, presumes that the sufferer is getting therapy, which he recommends. If they’re not, what would he do?)  He does imply that there are data bearing on this issue, though he doesn’t cite any. He does say this:

Epidemiological studies show that many people are exposed to trauma in their lives, and most have had transient stress symptoms. But only a minority fails to recover, thereby developing P.T.S.D. Students with P.T.S.D. are those most likely to have adverse emotional reactions to curricular material, not those with trauma histories whose acute stress responses have dissipated.

However, trigger warnings are countertherapeutic because they encourage avoidance of reminders of trauma, and avoidance maintains P.T.S.D. Severe emotional reactions triggered by course material are a signal that students need to prioritize their mental health and obtain evidence-based, cognitive-behavioral therapies that will help them overcome P.T.S.D. These therapies involve gradual, systematic exposure to traumatic memories until their capacity to trigger distress diminishes.

Rather than issuing trigger warnings, universities can best serve students by facilitating access to effective and proven treatments for P.T.S.D. and other mental health problems.

This seems a bit harsh, for if I was going to show a picture of, say, somebody with a terrible war injury, I wouldn’t hesitate to warn students just before. Even if you don’t have P.T.S.D., maybe you can be more prepared—or even, in this one case, look away.

To see the diversity of subjects that people have said should be subjected to trigger warnings, here’s a list from Kyriarchy and Privilege:

screen-shot-2016-09-18-at-11-57-43-am

You can see how difficult it would be to have to issue trigger warnings for people—look at the last item, for instance!

Finally, of the three items mentioned in the University of Chicago letter—trigger warnings, safe spaces, and a policy not to disinvite speakers—trigger warnings is the one most easily resolve. The University was not saying they cannot or should not be used, but that the U of C doesn’t mandate them; it leaves them up to faculty. Safe spaces is a difficult issue that the letter might have discussed in more detail, though it specified “INTELLECTUAL safe spaces,” i.e., free discussion in the classroom. And I see no good argument against my University’s policy of not disinviting speakers. I have little doubt that it will soon have a policy, too, for sanctioning students who try to interrupt or “shut down” speakers.

More Egnorance about Darwin and language in the Washington Post

September 18, 2016 • 9:30 am

Well, given the number of comments on my review in the Washington Post of Tom Wolfe’s abysmal new book on Darwin, Chomsky, and the evolutionary basis of language (Wolfe says there is no such basis), I shouldn’t have been surprised that there would be pushback from readers. But what I didn’t expect was that one of the two letters published would be from a creationist. Yes, like a dog returning to its vomit (Proverbs 26:11), intelligent-design creationist neurosurgeon Michael Egnor, whose obsession with me is regularly on parade at the Discovery Institute website Evolution News and Views, couldn’t resist commenting.

Egnor had no beef with my “defense”—such as it was—of Chomsky, but he sure didn’t like my defense of Darwin. The curious thing is that, contrary to Egnor’s claim, I didn’t defend Darwin’s own views on language, which were rudimentary and fanciful, but rather the proposition that there is some genetic basis for the human use of language. I also called out Wolfe for his ignorant claim that there is no evidence for evolution, and that it neither explains any biological puzzles nor makes any predictions.

Egnor, of course, ignores my own comments in favor of casting doubt on the whole evolutionary enterprise on the basis of speculations that Darwin made about language. (By the way, Dr. Egnor, Darwin was right about evolution, natural selection, and common ancestry of all organisms.) Egnor apparently believes that language is a gift of the Unspecified Designer. And, as you might expect, he doesn’t identify himself as an intelligent-design creationist, which of course would cast doubt on his competence. Here’s his letter:

Jerry A. Coyne’s review of Tom Wolfe’s book “The Kingdom of Speech” [“Tom Wolfe should stop posing as an evolutionary biologist,” Outlook, Sept. 4] was a mixed bag. Coyne was right to defend Noam Chomsky from Wolfe’s attacks. Chomsky’s theories of universal grammar and recursion are supported by massive evidence and landmarks in modern linguistics and neuroscience. Chomsky has earned the respect of the scientific community. [JAC: This isn’t true—there is huge controversy about Chomsky’s theories, which I noted in my review.]

Coyne, however, was wrong to defend Charles Darwin from Wolfe’s scathing critique. As Wolfe pointed out, Darwinian stories about the origin of human language are pitifully inadequate. Human language bears no relation to the crude signals and gestures of animals. Nothing in the animal realm is a precursor to universal grammar or to the semantic subtlety of recursion — the layered meaning packed into clauses-within-clauses used routinely by all human beings.

Human language is sui generis. It is a window into the human soul, and it lacks any credible Darwinian roots. Wolfe is to be commended for bringing this fascinating discussion into the public forum.

Michael Egnor, Stony Brook, N.Y.

Go back to my original review and look again at my defense of Darwin.

*********

But this second letter, from the director of an institute in Massachusetts that specializes in treating autistic children, is in some ways more disturbing, because you expect someone who treats autism to be a bit more rational:

Tom Wolfe is to be applauded for his new book, The Kingdom of Speech,” in which he posits that speech, contrary to Noam Chomsky’s position, did not arise from evolution but rather is a direct human creation. For those teaching children with autism, this truth is evident every day.

A primary diagnosis of autism is lack of speech and social interaction. For this large population, language is neither inherited nor instinctually structured, as Chomsky believes. The key to establishing language for those with autism is teaching functional communication, including alternative methods: sign language, pictures, touch-to-speak technology and mobile apps.

This functional approach is grounded in the science of applied-behavior analysis, proving Chomsky’s structural theory false. For the Chomsky school, nature is weighted over nurture. In our experience, nurture is the path by which those with no speech skills can achieve meaningful communication.

If language were an innate characteristic rather than something that could be acquired, there would be no option for a child who can’t speak. As those who teach children with autism know, this is clearly not the case. Teaching language, regardless of form, is a powerful tool to allow individuals diagnosed with autism to lead richer lives.

Vincent Strully Jr.,
Southborough, Mass.

The writer is founder and chief executive of the New England Center for Children.

Here Mr. Strully argues that because you can help autistic children learn to communicate through sign language and other non-speech-related techniques, language cannot have a genetic basis. This fallacy, that cultural intervention can’t change a trait if it has a genetic/evolutionary basis, is as old as modern biology.

Autism causes problems with communication and social interaction, and, as Strully notes, there are environmental interventions that can promote communication. Further, although we don’t understand the precise neural or physiological basis of autism, the condition is not only biologically based, probably representing some neural malfunction, but also has some genetic basis (it’s passed on) as well as some environmental influences, and this complex nexus of genes and environment, as well as difficulties with diagnosis, results in a highly variable condition—the “autism spectrum”.

Deafness, too, which also impedes communication, often has a genetic basis, but deaf people can use (and even invent) sign language without even being taught. But the existence of that language has no bearing on the biological basis of deafness.  Maybe Mr. Strully finds that easier to grasp.

But as biologists (and rational folks) have long realized, the fact that a biological “malfunction” (like diabetes) can be cured or ameliorated does not mean that the “normal” condition (language, in the case of autism) is not based on genes and evolution. Strully’s argument—that autistic children learning to communicate shows that language has no basis in “nature” (genetics/evolution)—is equivalent to saying this: the fact that we can correct defective vision with eyeglasses is evidence that the eye did not evolve. Or, as Strully might say:

A primary diagnosis of myopia is an inability to focus the eye properly. For this large population, the eye itself is not inherited. . . In our experience, nurture (wearing glasses) is the path by which those with poor vision can achieve better sight.

Frankly, I’m appalled that Strully fell victim to a fallacy like this.

Readers’ wildlife photographs

September 18, 2016 • 8:45 am

It’s been a while since we’ve heard from Lou Jost, a biologist, naturalist, artist, and photographer who works in Ecuador, but I have a feeling we’ll have more photos from him soon (and, if Hillary wins, he’ll owe me some dosh). The first batch of his pictures sent shows a marvelous bird. His notes are indented:

My shower is outside, with the shower head tied to a tree. I was taking a shower today when one of my favorite birds, a secretive Golden-crowned Tanager (Iridisornis rufivertex), came up through the undergrowth and landed at my feet. I was washing normally and moving a lot, but this bird must have really wanted a shower. It sometimes stood only a foot or two away from me. I finished washing and got my camera and photographed him still there enjoying himself. Other species of birds also approached at the same time. The sound of falling water is irresistible to many birds, but this is the first time they tried to join me while I was showering! It was one of my nicest wildlife experiences ever.

Here’s a photo, from the Cornell Neotropical Birds Site, of the tanager when it’s not wet:

I also wrote Lou, in light of the amazing cryptic “lichen katydid” that I posted a few days ago, whether he’d seen anything like it in Ecuador. His response (and a photo):

Yes, I have excellent pictures of it in lichens from Costa Rica, but they are on film and I haven’t scanned them yet. But a few weeks ago I found a different species of lichen katydid here in one of our reserves. Here it is, different from the one you showed last week. This is more robust and was found at 1300m elevation in the understory of our Rio Zunac Reserve in eastern Ecuador.
