B. F. Skinner: Brilliant Engineer, Brilliant Self-Promoter, Mediocre Scientist

I majored in psychology at Reed College. At the time, the whole major centered on Skinnerian psychology — the importance of reward in controlling behavior. The introductory course used a Skinnerian textbook (e.g., we learned the correct meaning of “negative reinforcement” — it does not mean punishment). Other courses also had a Skinnerian emphasis. They never convinced me. I always thought it was an exceedingly narrow way to study behavior.

When I was a graduate student, I visited Harvard and heard Skinner give a talk, titled “Why I am not a cognitive psychologist”. During the question period I asked if he was familiar with the work of Saul Sternberg — perhaps the most influential cognitive psychologist. No, said Skinner. I thought it was foolish to criticize an area of research you know little about.

After I became a professor, I went back to Reed to give a talk. After the talk, I went out to dinner with several psychology professors. I told them I thought Skinner was a brilliant engineer — the Skinner box is really useful — but a mediocre scientist. He was unable to discover anything, he just repeated the same result (rewarding something increases how often it is done) countless times. They had no reply.

In the last two days, strangely enough, Skinner has come up in two different conversations. In the first, a friend said that Skinner’s views about language were ridiculous. I agreed. Why write such nonsense? my friend asked/complained. I said maybe Skinner’s productivity system worked too well. It caused him to write when he had nothing to say. In the second, a different friend brought up David Freedman’s recent Atlantic article called “The Perfected Self”, which argues that Skinnerian techniques really work when you implement them as smartphone apps — techniques to lose weight, for example. “B. F. Skinner’s notorious theory of behavior modification was denounced by critics 50 years ago as a fascist, manipulative vehicle for government control,” writes Freedman (or an editor), but actually that theory is really good.

My area of academic psychology (animal learning) is the same as Skinner’s. Within this field, I have never heard anyone complain that Skinner’s work was “fascist” or “manipulative” or a “vehicle for government control.” It never became popular — it was always a minority point of view — probably because it was boring (the same thing over and over) and perhaps because it was anti-intellectual. Skinner wrote a well-known paper about why theories are unnecessary. He didn’t understand the role of theories in science and didn’t bother to find out. Sure, the psychology theories of the time (1950) were awful. Psychology theories are still mostly awful. But there are plenty of good theories in other areas of science.

For a long time, Skinnerian ideas, nearly dead in academia, lived on in the treatment of autism. The people applying these ideas called themselves “behavior analysts” and the whole field of applied Skinnerian psychology was called “behavior analysis”. What caused this persistence was that the techniques worked. Using the techniques (carefully rewarding this or that behavior) improved the lives of autistic children and their parents. Which was a real contribution. I could make a long list of famous psychologists who have done less to improve human well-being.

The success of Skinnerian ideas in improving the lives of autistic children should not be confused with figuring out what causes autism. To figure out the cause of autism is to figure out the environmental cause(s) — to which people with certain genes are more sensitive — and how autism can be avoided entirely, not meliorated. I have blogged about possible causes of autism many times, in particular the possibility that sonograms cause autism. I have no idea if behavior analysts understand the difference between melioration and figuring out the cause. Maybe Skinner would claim there is no difference — he was full of bizarre statements like that. If your child is autistic, you are in crisis. You have zero interest in questions about “cause” — you simply want help. In any form. Behavior analysts, while helping autistic children and their parents, contribute nothing that helps us find the cause of autism. Which, if you are planning on having children, you care about enormously. So you can avoid having autistic children.

So Skinner’s legacy is mixed. The Skinner box is terrific. I happily used them in my research for years, even though I hardly believed a single word Skinner said. As an engineer — an applier of stuff discovered by others — Skinner made a lasting contribution. As a self-promoter, he was incredibly successful — he was on the cover of Time, for example. As a scientist, he was a zero. He discovered nothing that matters. As a thinker (e.g., the book Beyond Freedom and Dignity) he was less than zero. He was a charlatan, claiming over and over that he understood puzzling things (e.g., language) that he did not understand. An unusual mix. Few great engineers are charlatans.

Acne: Reality is Not a Morality Tale

Someone named Red Fury made an interesting comment on my Boing Boing article about acne:

I had acne on/off for years. . . . In my mid-thirties, I tried the Retin-A at night, antibiotic gel for day regimen for about 2 years – no effect. . . . Then, I was talking to a co-worker whose daughter was taking ‘modeling classes’ to become a teen model. She casually mentioned her acned daughter had to give up rice, potato chips, and bread, all of which are high-glycemic index foods. My quack-radar went off, and I looked around for something scientific behind that advice. https://www.ajcn.org/content/86…

Huh. I guess those nutrition-bashing dermatologists actually did a study and published the scientific results in a peer-reviewed journal. . . . My acne disappeared completely as soon as I eliminated rice and potatoes.

He finds a study that supports the casual advice, he follows the advice, his acne disappears. By convincing him to follow the advice, the scientific study helped him get rid of his acne. Which is impressive.

The interesting twist is that the study was published twice, clearly breaking the rules. Bad scientists! Who did something really good.

“How We Stopped SOPA”: Talk by Aaron Swartz in New York

Aaron Swartz was a key figure in the successful fight against SOPA (Stop Online Piracy Act). On Thursday (August 16) he will tell how a tiny number of online activists managed to defeat a bill pushed by the entertainment industry, which had spent hundreds of millions of dollars per year trying to get it passed and believed its survival was threatened if it wasn’t passed. Aaron will speak at 7 pm at ThoughtWorks, 99 Madison Avenue, 15th floor, New York NY.

Eliminating Nocturnal Urination

A male reader who wishes to be anonymous writes:

I am 53. When I was in my late 40s I started having to wake up to urinate in the middle of the night. Sometimes more than once. I complained to the physician. He said, “That’s BPH [= benign prostatic hyperplasia = enlarged prostate]. It’s what happens in middle age. Live with it.”

A couple years later on an airplane, I read an article about pygeum [a herbal remedy] as a cure for BPH. I started taking some. It helped, but not a lot. Reading about pygeum I stumbled across saw palmetto. I started taking a supplement that contained both of them. Now I was much improved, but there was still room for improvement.

A friend told me about magnesium supplementation. I started taking magnesium in addition, and I was cured. It’s like I’m in my 30s again. I only have to urinate in the middle of the night if I drink a lot of fluid right before bed.

Sleep is so important, this is really important. At a talk Thursday at the Ancestral Health Symposium, Robb Wolf quoted someone as saying, “If someone sleeps well, you can’t kill them; if they sleep badly, you can’t keep them alive.”

Edward Jay Epstein Reviewed Movies For Vladimir Nabokov

Edward Jay Epstein attended college at Cornell. When he was a freshman, he took Vladimir Nabokov’s lecture course about European and Russian literature. Nabokov told his students that a great writer creates pictures in readers’ heads. One of the exam questions, about Anna Karenina, was Describe the train station where Anna met Vronsky.

Epstein hadn’t read the book. However, he had seen the movie, so he described in great detail the train station in the movie. After the exam, Nabokov asked to meet him. Epstein told him he hadn’t read the book. Nabokov said it didn’t matter, and gave him an A. He offered Epstein a job. Ithaca had four movie theaters. Movies were released on Wednesday, so every Wednesday each theater would have a new movie. Nabokov loved movies. He went on Friday. He wanted to know which movie to choose. Epstein’s job, for which he was paid, was to watch all four movies and report back.

Epstein did this conscientiously but in retrospect, he said, one of his comments was a mistake. The Queen of Spades (from Pushkin’s story) was one of the movies. Epstein told Nabokov it reminded him of Dead Souls. (They were reading Dead Souls in class.) This interested Nabokov. He looked at Vera, his wife, who was sitting at his desk facing him. He asked Epstein why The Queen of Spades reminded him of Dead Souls.

“They’re both Russian,” said Epstein.

More: Epstein tells the story himself.

How Martha Rotter Cured Her Acne By Self-Experimentation

Several months ago I posted about how Martha Rotter figured out that her acne was caused by cow dairy products. Now a longer version of her story (by me) is on Boing Boing. There is a ton of useful information in the comments. Some examples:

Dairy is what caused my acne.” Someone replied: “Same here, specifically milk. I switched to soy milk in high school and my moderately-bad acne went away very suddenly. . . . If I eat a lot of cheese at once, like having pizza more than a couple days a week, my backne gets worse and I get acne inside my ears.” Someone else misunderstands genetics: “I do have tumor-forming disease (fortunately stable, and partially corrected with surgery) so I do have some sympathy when it comes to this sort of thing, but my condition is so well established as genetic I never even saw hope in trying to control it with diet.” Aaron Blaisdell had a well-established genetic condition (porphyria) that went away when he changed his diet.

Someone else found that dairy mattered:

I had terrible acne as a teenager and I drank almost a carton of milk every day. . . . When I moved out on my own, I no longer had milk delivered at the door and I fell out of the habit of drinking it altogether, switching to tea and water instead. My face cleared within weeks. . . . Whenever I indulged in cheese, the break-outs returned.

Someone else discovered multiple causes:

I have had strikingly similar experiences with a very particular form of acne, for years. Multiple doctors with no results until I got frustrated with it. I heard that the four most common causes of skin reactions can be wheat, milk, peanut butter and eggs – so I took all of them out *and* meat.

And watched my skin slowly return to normal.

After playing with my food by putting one thing in, seeing what happened, and then taking that out and trying something else, I found that wheat in particular is the trigger for me with dairy as a close second.

Someone else: “I took wheat from my diet, and my skin cleared up. If I allow wheat back in for one day, the next day I have acne.”

Not all solutions were dietary:

My wife and I found the only thing that worked reliably–even including a couple of different kinds of antibiotics–was “the regimen” as described on acne.org. Basically you use a low-strength (2.5%) benzoyl peroxide every day and moisturise like mad afterwards.

These are just examples. There are many more helpful comments.

Tyler Cowen’s Unusual Final Exam

In a discussion of college education — I believe there should be more allowance for human diversity — sparked by this post, Alex Tabarrok told the following story:

Tyler [Cowen] once walked into class the day of the final exam and said, “Here is the exam. Write your own questions. Write your own answers. Harder questions and better answers get more points.” Then he walked out. The funniest thing was when a student came in late and I had to explain to him what the exam was and he didn’t believe me!

I was impressed. This approach, unlike most exams but like actual economies, rewards rather than punishes specialization. I asked Tyler what happened. He replied:

I would say that the variance of the test scores probably increased!

I don’t recall if I ever did that again for a whole exam but most of my exams do that for at least one question. It’s the question where you learn the most about the student.
