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.

Spot the mantis!

September 18, 2016 • 7:45 am

Reader Mark Sturtevant sent us another stumper:

I found several praying mantises this summer, and one of them is here somewhere. This was taken when I had released it after taking a number of close up pictures. Can the readers of WEIT find it? Happy hunting!

I’ll post the answer at 11 a.m. Chicago time. If you spot it, please refrain from giving the location in the comments below, though feel free to pat yourself on the back! Note, though, that it is PRAYING mantis, not PREYING mantis; this is a mistake that is common. They do prey, but they look as if they’re praying.

Sunday: Hili dialogue

September 18, 2016 • 7:00 am

Hili is late today, as Professor Ceiling Cat Emeritus overslept, but he needed it!  It’s Sunday, September 18, and will be a nice sunny day in Chicago. The first-year students have arrived on campus to begin their “orientation” (aka indoctrination), and I’ve made yet another bet on Hillary winning the Presidency: I’ll get a fancy meal in Hyde Park if she wins. This is, I believe, the fourth such bet I’ve made, and, since I firmly believe Clinton will win, I have no compunction about taking money from those  willing to bet because they have a desperate fear that Trump will win. “You can’t lose,” I tell them. “If Trump wins, you get a free dinner (or money). If he loses, you’ll be so glad that you’ll be happy to pay me off.”

It’s National Cheeseburger Day, though I’m planning on having a Mexican sandwich, a cemita, at a newly opened local joint.  On this day in history, in 1919, the Netherlands gave women the right to vote (“gave”, of course, implies that a favor was being conferred), and, exactly two years ago, Scotland voted against independence from the UK. The results might well be different in the next referendum!

Notables born on this day include Robert Blake (1933), Ben Carson (1951), and Tara Fitzgerald (1967 ♥). Those who died on this day include Dag Hammarskjöld (1961), Jimi Hendrix (1970), and Katherine Anne Porter (1980). Meanwhile in Dobrzyn, Hili is demanding fusses to soothe her in the open, where she gets a bit freaked out:

Hili: Stroke me once more and we will see.
Malgorzata: See what?
Hili: Whether it’s enough.

In Polish:
Hili: Pogłaszcz mnie jeszcze raz, a potem zobaczymy.
Małgorzata: Co zobaczymy?
Hili: Czy wystarczy.

C. S. Lewis: Evolution denialist?

September 17, 2016 • 2:04 pm

It’s extremely painful working my way through C. S. Lewis’s Mere Christianity: I still can get through 20 pages at most before I have to stop in disgust. Fortunately, I have only about 100 pages to go, and the pages are small. My revulsion may be due to having been crammed to the maw with theology when I wrote my last book.

Up to now in Mere Christianity, Lewis has said nothing about evolution, though the video below says there’s a small bit later on. Still, I wondered what a man as smart as Lewis would make of the theory of evolution, and the video below, “suggested” by YouTube, answers the question. Sadly, his views on evolution are even worse than his views on Christianity. Though Lewis died in 1963, when we already had tons of evidence for evolution, Lewis was a doubter, apparently holding the following views:

  • He had no objection in principle to common ancestry, but was skeptical about it—exactly the view that Michael Behe holds.
  • He was especially skeptical about human evolution, not seeing how natural selection could create the reasoning human mind.
  • He saw materialistic natural selection, the “unguided version,” as incapable of creating novelty; it could “knock out existing functions” but not create new ones. This of course is a stock argument of creationists.
  • Insofar as natural selection were creative, God would have to be guiding it. Thus, the form of  “natural” selection accepted by Lewis was really “unnatural” because it was guided by God. In other words, Lewis was in part, a theistic evolutionist, and in part a creationist.
  • In his book Miracles, Lewis claimed that human reason could not have been produced by materialistic natural selection, for if selection is a “blind” process, how can we regard reason as giving us the ability to uncover the truth? This is very similar to the arguments of Sophisticated Theologians™ like Alvin Plantinga, and is a specious argument. I explained why in Faith Versus Fact. 
  • Lewis also claimed that if humans evolved in a Darwinian way, we would have no reason to prefer morality over immorality, as there would be “no such thing as right or wrong.” Real atheists would have to admit that, he said.
  • As Lewis got older (and as the study of evolution advanced), he became even less accepting of evolution, proclaiming that the dogmatism of evolutionary biologists convinced him that  evolution was the “central and radical lie in the whole web of falsehood that now governs our lives.” It’s almost as if he thought evolution was a tool of Satan (in whom Lewis believed).
  • Finally, Lewis was an anti-accommodationist, critical of those who tried to reconcile evolution with theism. That’s the only thing he got right!

At the end of the video, the narrator praises Lewis for his expansive view of science, saying that science should not rule some questions as off-limits, as evolution supposedly does. The narrator says that evolutionists adhere dogmatically to the idea that most of our DNA is useless junk, and thus can’t accept that most of it is function, as God would of course have intended. Sadly, the narrator is wrong. It’s unfortunate for him and for god that most of our DNA does appear to be junk, and this video was made before a reanalysis of the ENCODE data showed that.

The narrator also disses vestigial organs, saying that we’ve discovered functions for some of them and hence they can’t be used to support evolution. But as I’ve said repeatedly, vestigial organs can still have some function while also serving as evidence for common ancestry (the flippers of penguins are one example). And there are simply some organs that are almost beyond having a conceivable function, such as the muscles that enable some humans to wiggle their ears (remnants of muscles used adaptively by our ancestors), as well as “dead genes” that have been rendered totally nonfunctional by mutations. What would Lewis say about the human genes for egg-yolk proteins that are broken–and produce no product at all yet are very similar in sequence to functional yolk-protein genes in reptiles and birds?

Have a listen below. I wonder if we can really call Lewis a “smart man” given not only his dim view of evolution but his deeply flawed theology.
