Rotten Fish are Everywhere

Seth Roberts2 Comments

Somebody anonymous with an amusingly-named blog became a vegan while working in a Thai restaurant:

Now here’s something surprising: my bosses were interested in helping me be a vegan. “Oh, that silly white boy and his eating experiments,” they’d say. Vang, the chef, learned to create delicious curry without fish sauce–learning how to dump plenty of salt and sugar into the coconut milk to compensate for the rotten fish. Plus, they introduced me the power of hot sauce, namely Sriracha Sauce–a love affair that continues to this very day. . . .

One of my uncles, who is possibly a little retarded and probably a little mentally ill, says that hot sauce kills all the germs in your body (yes, he claims all of them), thus making it impossible to get sick.

No, it’s the rotten fish that does that.

A Brilliant Business: Selling Soap Nuts Online

Seth Roberts5 Comments

I came across Laundry Tree while trying to figure out what soap nuts are. Soap nuts grow on trees and contain a soap. You can use them in place of laundry detergent. Something I read linked to the Laundry Tree site because it had a good picture.

I clicked around the site and was very impressed.

  • Attractive web design. Easy to navigate.
  • Neither hard nor soft sell. It’s plainly an e-tail site but it doesn’t hit you over the head with that nor does it hide it.
  • Signs of life. Unlike, say, www.sethroberts.net, you can see that the home page has been updated recently.
  • A friendly tone of voice.
  • An interesting way to get visitors involved — a blogger’s contest (which this post will not enter me in).
  • Persuasive.

And that’s just the website. None of the elements are rare yet the website itself stood way out from the zillions of websites I visit. I admire the whole business. It solves a real problem. It’s unusual. It’s very small. The owner puts little at risk, pays almost zero rent, and feels she’s making the world a better place in her own almost-unique way. Very few businesses manage to hit all of these marks.

I’m sure I would admire Laundry Tree no matter what I did with my life. Being a professor is very far from being a small business owner. But the self-experimentation I have done has a lot in common with Laundry Tree.

First, it began with trying to solve my own problems. I wanted to reduce acne, sleep better, lose weight. Laundry Tree began when the owner wanted a better way of doing laundry — no dyes, no harsh chemicals, not sudsy, and not expensive.

Second, it blends male and female tendencies. The data-analytic statistical-software number-crunching rigid-experiment side of self-experimentation is obviously male. The talk-about-my-problems side is obviously female. Likewise, Laundry Tree centers on a problem — choosing a good laundry detergent — that concerns women more than men. Yet constructing and maintaining a website is a kind of technical work that men seem to enjoy more than women. (Nowadays, I admit, it isn’t very technical.)

A journalist friend of mine was given an assignment to write about self-experimentation but eventually turned it down when he couldn’t find enough examples. I think the need to blend male and female tendencies is the main reason it is so rare. (At least publicly.) To get somewhere you really do have to make numerical measurements, enter the data, plot the data, and so on — stuff that, historically, men do far more than women. Yet to talk about your results you really do have to admit to everyone you have (or at least had) a problem, which men find much harder to do than women.

The Quantified Self Meetup group is having a meeting this Tuesday (Jan 27) — two days from now — at the UC Berkeley School of Information, 6 pm. The dozen or so projects I’ve heard about related to this group always invove quantification but rarely experimentation. In my experience quantification without experimentation doesn’t get very far but perhaps they will eventually learn this (or perhaps I’m wrong). Experimentation and quantification is more difficult than quantification alone but only a little more difficult. Perhaps the reason for lack of experimentation is that with quantification alone you stay safely on the male side of things but to add experimentation (to solve a personal problem) and talk about it you have to cross over to the female side.

Not the Same Study Section: How the Truth Comes Out

Seth Roberts9 Comments

In the latest Vanity Fair is a brilliant piece of journalism, Goodbye to All That: An Oral History of the Bush White House by Cullen Murphy and Todd Purdum. In a fun, easy-to-read format, it tells some basic truths I had never read before. Here are two examples:

Matthew Dowd, Bush’s pollster and chief strategist for the 2004 presidential campaign: When Abu Ghraib happened, I was like, We’ve got to fire Rumsfeld. Like if we’re the “accountability president,” we haven’t really done this. We don’t veto any bills. We don’t fire anybody. I was like, Well, this is a disaster, and we’re going to hold some National Guard colonel responsible? This guy’s got to get fired.

For an M.B.A. president, he got the M.B.A. 101 stuff down, which is, you know, you don’t have to do everything. Let other people do it. But M.B.A. 201 is: Hold people accountable.

David Kuo, deputy director of the White House Office of Faith-Based and Community Initiatives: There’s this idea that the Bush White House was dominated by religious conservatives and catered to the needs of religious conservatives. But what people miss is that religious conservatives and the Republican Party have always had a very uneasy relationship. The reality in the White House is if you look at the most senior staff you’re seeing people who aren’t personally religious and have no particular affection for people who are religious-right leaders. Now, at the end of the day, that’s easy to understand, because most of the people who are religious-right leaders are not easy to like. It’s that old Gandhi thing, right? I might actually be a Christian myself, except for the action of Christians.

And so in the political-affairs shop in particular, you saw a lot of people who just rolled their eyes at everyone from Rich Cizik, who is one of the heads of the National Association of Evangelicals, to James Dobson, to basically every religious-right leader that was out there, because they just found them annoying and insufferable. These guys were pains in the butt who had to be accommodated.

This is related to the Shangri-La Diet. In these two excerpts, the speakers were (a) close to the events they describe but (b) not so close they are in any danger from the people they tell the truth about.

In science the same thing happens. Saul Sternberg and I could tell the truth about Ranjit Chandra’s research not only because (a) we were fairly close to that research (which involved psychology, even though Chandra was a nutritionist) but also because (b) not being nutrition professors, Chandra couldn’t harm us. Those closer to Chandra, professional nutritionists, had plenty of doubts as far as I could tell but were afraid to say them. Hal Pashler and I could criticize a widely-accepted practice among cognitive modelers because (a) we were in the same general field, cognitive psychology, but (b) far enough away so that the people we criticized would never review our grants or our papers. (Except the critique itself, which they hated. After the first round of reviews, Hal and I requested new reviewers, saying it was inevitable that the people we criticized wouldn’t like what we said.) Likewise, in the case of voodoo correlations, Hal is (a) close enough to social neuroscience to understand the details of the research but (b) far enough away to criticize it without fear.

In the case of the Shangri-La Diet, I was (a) close enough to the field of nutrition that I could understand the research but (b) far enough away so that I could say what I thought without fear of reprisal. Nassim Taleb is in the same relation to the field he criticizes. Just as Saul Sternberg and I knew a lot about the outcome measure (psychological tests) but were not nutritionists, Weston Price, a dentist, knew a lot about his outcome measure (dental health) but was not a nutritionist.

It’s curious how rarely this need for insider/outsiders (inside in terms of knowledge, outside in terms of career) is pointed out. It’s a big part of how science progresses, in small ways and large. Mendel and Darwin were well-educated amateurs, for example. Thorstein Veblen wrote about it but I haven’t read it anywhere else.

Powdered Ice Cream

Seth Roberts1 Comment

At the Fancy Food Show, Kriss Harvey, a pastry chef and frozen dessert solutions specialist, served me a spoonful of powdered chocolate ice cream, his invention. It looked like chocolate ice cream but it tasted unlike any ice cream (or any food) I’ve ever had. It was there and not there. It was in my mouth and then it was gone. It was the most ethereal food I’ve ever had.

We had been talking about El Bulli, the Spanish restaurant of experimental food. Two friends of Mr. Harvey’s had worked there one summer and had come back complaining about the food (rabbit ears) and the workload. Just because people will pay a lot for your unusual food doesn’t mean you are advancing things, said Mr. Harvey. Maybe your food doesn’t taste very good. He pointed to a certain now-forgotten fad among New York dessert chefs a few years ago. That’s fashion, I said; it has a perfectly good purpose (to support experimentation). Then Mr. Harvey served me his powdered ice cream. Which was more memorable and impressive than anything I had at Alinea, an American version of El Bulli.

Beijing Shopping (stuff easy to get in Beijing but not Berkeley)

Seth Roberts8 Comments

Jane Jacobs said that one measure of a healthy economy is the choice it provides. A healthy economy provides abundantly at affordable prices; an unhealthy economy does not. Another sign of economic health, she said, is innovation: A healthy economy includes a constant stream of new products — nothing lasts forever. People in Norway are far richer than people in China right now, but what will Norwegians do when the oil runs out?

In contrast, my Beijing shopping revealed that Chinese entrepreneurs have been able to develop products that the rest of the world will want to buy.

1. Electric bikes. They’re everywhere in Beijing. They cost $200-$400 and a few cents per mile, far cheaper than gas. I would have brought one back to Berkeley but inability to fix it stopped me.

2. Keyboard covers for laptops. Transparent silicone plastic. Easy to clean. How did I live without one? These are a new product in Beijing, actually, but they are very cheap, about $1. I can find them for sale on the internet for about $15.

3. Cordless floor sweepers. They use a rotating brush to clean the floor instead of a air pump, as a vacuum cleaner does. That they are cordless makes them very easy to use. In Beijing they are obvious and attractive; I bought two and brought one back to Berkeley. In America I’d never seen them for sale but after I knew they existed I managed to find an unattractive one in Berkeley hidden deep in a hardware store. The price (about $50) was roughly the same in Beijing and Berkeley, except the Beijing models are much nicer.

I don’t think it’s a coincidence that all three products are “environmental” broadly conceived. Beijing air is dirtier than Berkeley air; my keyboard cover and my floors get dirty a lot faster in Beijing than in Berkeley. I think they are a sign of hugely-important things to come — China inventing and selling the products we need for a cleaner world. It’s been called the next industrial revolution; a better name would be the second half of the industrial revolution in which we clean up the mess left by the first half. As Jane Jacobs often said, the problem is not too many people, the problem is the undone work.

Better Sleep, Fewer Colds

Seth Roberts6 Comments

In my long self-experimentation paper I described how I stopped getting colds when my sleep improved due to more standing and morning light. It was easy to notice: Everyone around me was getting sick and I wasn’t. In Beijing this winter the same thing happened: Lots of people around me got colds — a friend of mine was even hospitalized — but I didn’t. This winter I continued to get lots of morning light — I cared enormously that my apartment was on the sunny side of the building — but in place of standing for 8 hours or more every day I stood on one leg four times (left leg twice, right leg twice) until exhaustion.

Plenty of other evidence links better sleep with better immune function. The latest comes from the Archives of Internal Medicine. In a survey-like experiment, researchers measured the sleep of subjects with a questionnaire for two weeks and then brought them to an isolation unit, exposed them to a cold virus, and waited to see if they developed a cold. Subjects who slept better were less likely to get a cold. It was a big effect: “Participants with less than 7 hours of sleep [per night] were 2.9 times more likely to develop a cold than those with 8 hours or more of sleep [per night].” I rarely sleep 7 hours but wake up feeling plenty rested, which suggests that my sleep is deeper than average.

Overall, I’m happy for the support of my findings. Better sleep has a three-fold benefit: you feel more rested (short term), you get colds less often (medium term), and your risk of heart disease goes down (long term). The morning sunlight I get corresponds to sitting outside in the shade for about two hours; the standing takes a total of about 40 minutes/day (with your leg bent most of the time). I usually watch a movie or TV at the same time and always look forward to it.

Thanks to David Cramer.

Kafkaesque Research Regulation

Seth RobertsLeave a comment

From the BMJ:

The local research ethics subcommittee, which comprised a pharmacist and layman with limited clinical experience, had concerns about possible drug interactions between amiloride and other drugs being taken by the study participants and hyperkalaemia and requested resubmission. Although we pointed out that the pilot was identical to one limb of the amendment that it had already approved, in September 2007 the full committee rejected the application for the pilot to be considered as a study amendment. We therefore had to make new submissions to the local ethics committee, Medicines and Healthcare Products Regulatory Agency (MHRA), pharmacy, insurance company, research and development department, and the local (Wellcome Trust) clinical research facility.

In Spain it takes years to get approval. By the time you get approval someone else has published the study you wanted to do. A nightmarish research environment is one more reason that persons with health problems should do their own research: try to find solutions themselves. I started long-term self-experimentation because I knew that conventional sleep research would never — at least, in my lifetime — help me understand why I often woke up too early. A common problem, easy to measure — but conventional sleep research is nearly impossible.

Can it get worse? Yes, in Russia.
