The OJ Group

At the CBC in Toronto, Sarah Kapoor, who did a story about the Shangri-La Diet, started what she called “the OJ group” — OJ meaning Ordinary Journalism. Journalism about ordinary life, like The Hunt.

Were formation of the OJ Group a chess move, I would give it two exclamation points. 1. It points out a major problem with standard journalism: Too much of it is about famous and powerful people doing boring things. 2. It gathers support. It is a way of persuading others and learning from them. 3. It criticizes by creating — as Michelangelo advised. My self-experimentation — about everyday concerns such as sleep, mood, and weight — might be called Ordinary Science. It is science about ordinary life using methods of ordinary life.

In The Theory of the Leisure Class, Thorstein Veblen argued that we care enormously about status display. The upper (leisure) classes display their status by conspicuously avoiding useful work (e.g., long fingernails) and by conspicuous waste (e.g., hood ornaments). Academics display status by avoiding work on useful questions. Such work is dismissed as “applied”, in contrast to “pure” research. The status of scientific work also depends on dimensions that Veblen doesn’t mention: 1. It is higher status to have someone else do something than to do it yourself. 2. Expensive research is higher status than cheap research. Thus my self-experimentation had three strikes against it: low-status topics, low-status participants (I’m not ordering anyone around), and low-status cost (cheap).

In journalism, like everywhere else, there is status by association. Writing about high-status people is higher status than writing about low-status people.

Outside a Chinese Test Site

In China, a two-day annual test, which ended Friday, determines what college high school graduates will attend. Outside a test site, an AP reporter heard this:

Wang said she has been cooking foods for her son that are considered particularly good for worn-out students, with plenty of vegetables and less grease.

“Oily foods, it’s bad for the brain, it makes the brain slow down,” she said.

Astute observation. Regular readers of this blog know that certain oily foods (those high in omega-3 fats) have the opposite effect. But I suspect Ms. Wang is right, that most oily foods (high in omega-6) do slow the brain down, perhaps because they replace omega-3 with omega-6.

The Twilight of Expertise (part 1)

In a TED talk, Stewart Brand pointed out that all over the world, poor villages — the same villages that Jeffrey Sachs seems to want to preserve — are vanishing. The people who lived in them have moved to squatter cities, where, according to Brand, there is zero unemployment and a much better life. Because Jeffrey Sachs’ interest in poor African villages seems to be recent, I am not surprised that he may end up on the wrong side of the helped/didn’t help ledger.

This is the general pattern with experts today: Sometimes they help, but often they make things worse. In a comment on an earlier post, Dr. Erika Schwartz called modern medicine “a system that more often harms than helps.”

We are living in the twilight of expertise because we now have alternatives to experts — better alternatives. Squatter cities are a new thing. They solve a very difficult problem (poverty) because they combine three things: (a) People care about themselves and their children (far more than any expert will ever care). (b) The technological knowledge behind the many small businesses (e.g., hair dresser, copy center, pirated videos, cell phones) that allow squatter cities to exist. And (c) something that brings the first two things — caring and know-how — together, namely the cities themselves. Of course, squatter cities owe nothing to Sachs-type experts.

The self-help self-experimentation I have done is another new thing. I solved the difficult problems of how to control my weight, my mood, my sleep, and a few other things related to omega-3, such as my gums. None of which I am expert in — I am not a weight-control expert, a sleep expert, etc. I attribute my success to the combination of the same three elements that come together in squatter cities: (a) I cared. I care about myself far more than experts care about most of the people they try to help. (b) Scientific knowledge — both statistical methods (e.g., exploratory data analysis tools) and basic behavioral science (e.g., the rat experiments of Israel Ramirez). (c) The ability to combine (a) and (b). Self-experimentation was a big part of this, but not the whole thing. My job as a professor and the research library system allowed me the time and opportunity to learn the scientific stuff. The flexibility of my job helped a lot. For example, I almost never had to use an alarm clock to wake up, which allowed sleep self-experimentation. The solutions I discovered are quite different from conventional solutions, but no more different than squatter cities are from what Jeffrey Sachs has prescribed.

Atul Gawande on Unofficial Research


Regardless of what one ultimately does in medicine—or outside medicine, for that matter—one should be a scientist in this world. In the simplest terms, this means one should count something. . . . The only requirement is that what you count should be interesting to you.

When I was a resident I began counting how often our surgical patients ended up with an instrument or sponge forgotten inside them. It didn’t happen often: about one in fifteen thousand operations, I discovered. But when it did, serious injury could result. One patient had a thirteen-inch retractor left in him that tore into his bowel and bladder. Another had a small sponge left in his brain that caused an abscess and a permanent seizure disorder. . . I found that the mishaps predominantly occurred in patients undergoing emergency operations or procedures that revealed the unexpected—such as a cancer when the surgeon had anticipated only appendicitis.

The numbers began to make sense. If nurses have to track fifty sponges and a couple of hundred instruments during an operation—already a tricky thing to do—it is understandably much harder under urgent circumstances or when unexpected changes require bringing in lots more equipment. Our usual approach of punishing people for failures wasn’t going to eliminate the problem, I realized. Only a technological solution would—and I soon found myself working with some colleagues to come up with a device that could automate the tracking of sponges and instruments.

Science in Action: Sunlight and Sleep (update)

Today I had lunch with a friend and said, “I’d like to sit outside.” I answered my phone indoors and went outside. I answered my email sitting outside.

I’m now convinced that more outdoor light exposure makes me sleep better — better in the sense that I wake up feeling like I have slept more deeply. Whatever sleep does, it has done more of it. I’m convinced because I have gotten this well-slept feeling after six or seven days during which I spent several hours more than usual outdoor and did not get this feeling after two days when I spent an average or less-than-average amount of time outdoors.

I have slept this well before, but only after standing for 9 or 10 hours, which wasn’t easy. (Nowadays I stand about 6 hours/day.) Whereas spending more time outside is easy. I’ve ordered a sunshade for my laptop.

I am going to start to measure my sleep quality with a rating and keep track of how long I spend outdoors.

Science in Action: Sunlight and Sleep (background)

Daniel Kripke, a professor of psychiatry at UC San Diego, has done lots of research on the effect of exposure to varying amounts of natural light. His subjects often wear meters that record the illumination level. His latest paper (2004) on the connection between outside light and sleep reports several weak correlations between amount of light exposure and sleep quality:

mesor log10[lux] [a measure of light exposure] was . . . positively correlated with sleep quality (rp = 0.17, p < 0.005), and negatively correlated with reported trouble falling asleep (rp= -0.17, p < 0.005), waking up several times a night (rp= -0.18, p < 0.001), waking up earlier than planned (rp= -0.09, p < 0.10), and trouble getting back to sleep (rp = -0.11, p < 0.025).

The introduction states:

Bright light has been recommended for treatment of various sleep disorders [13], but very few experimental trials have been reported.

“Very few” seems to mean none, given the absence of citations.

The paper ends:

In conclusion, low illumination has a small relationship to . . . sleep disturbances.

Science in Action: Omega-3 (conference submission)

A few days ago I submitted a title and abstract for a talk to be given at the November 2007 meeting of the Psychonomic Society, a group of experimental psychologists:

Rapid Effects Of Omega-3 Fats On Brain Function

I measured the effect of omega-3 fats on my brain by comparing flaxseed oil (high in omega-3) with other plant fats (low in omega-3) and with nothing. Flaxseed oil improved my balance, increased my speed in a memory-scanning task and in simple arithmetic problems, and increased my digit span. The first three effects were very clear, t > 6. The effects of flaxseed oil wore off in a few days and appeared at full strength within a day of resumption. The best dose was at least 3 tablespoons/day, much more than most flaxseed-oil recommendations. Supporting results come from three other subjects. Because the brain is more than half fat, it is plausible that type of dietary fat affects how well it works. The most interesting feature of these results is the speed and clarity of the improvement. The tools of experimental psychology may be used to determine the optimal mix of fats for the brain with unusual clarity.

If I ever made a time line for my life, this submission would be one of the events.

Science in Action: Flavor-Calorie Learning (simple example)

The Shangri-La Diet is partly based on the idea that we learn to associate flavors and calories. A food’s flavors become associated with the calories in the food. This association makes the flavor more pleasant.

I would like to learn more about this associative process so I have been studying it. Here is a simple example. At intervals of a day or so between bottles, I drank 4 bottles of a lemongrass-flavored soda. I chose that flavor because it was unfamiliar. Each bottle had 50 calories of cane sugar. I rated how pleasant each bottle tasted on a scale where 40 = slightly unpleasant, 50 = neutral, 60 = slightly pleasant, and 70 = somewhat pleasant. I drank the bottles between meals — far away from other food.

Here are the ratings.

The flavor gradually became more pleasant.

The Secret of My Success

Jane Jacobs said dozens of things that impressed me, this most of all:

You can’t prescribe decently for something you hate. It will always come out wrong. You can’t prescribe decently for something you despair in. . . . I think people [who] give prescriptions, who have ideas for improving things, ought to concentrate on the things that they love and that they want to nurture.

She had noticed that people who hate cities or who despair of cities make bad prescriptions for them.

It was a long time before I realized this comment applied to me. I used self-experimentation to improve my sleep and mood and to lose weight. Unlike most health researchers, I wasn’t trying to solve other people’s problems — I was trying to solve my own. No wonder I persisted in spite of many failures.

Similar advice. Another example.
