Boston Magazine has a fascinating article on the work of psychologist Lisa Feldman Barrett who has been leading the charge against the idea that we recognise the same facial expression of emotion across the world.
This was first suggested by Paul Ekman whose work suggested that humans can universally recognise six emotions: anger, disgust, fear, happiness, sadness, and surprise.
His research involved showing people from different cultures pictures of faces and asking them to label each expression from a choice of emotional words.
But Barrett has found a simple flaw in the procedure:
She returned to those famous cross-cultural studies that had launched Ekman’s career—and found that they were less than watertight. The problem was the options that Ekman had given his subjects when asking them to identify the emotions shown on the faces they were presented with. Those options, Barrett discovered, had limited the ways in which people allowed themselves to think.
Barrett explained the problem to me this way: “I can break that experiment really easily, just by removing the words. I can just show you a face and ask how this person feels. Or I can show you two faces, two scowling faces, and I can say, ‘Do these people feel the same thing?’ And agreement drops into the toilet.”
The article is on much more than this controversy in cognitive science and also tracks how research on emotion and facial expression is playing an increasing role in law enforcement – with not all of it well supported by evidence.

These days, even those of us who eat healthy most of the time still end up eating at a fast food restaurant here and there. And nothing goes with a burger quite like French fries. Unfortunately, French fries are one of the least healthy foods out there. Even cheeseburgers give you some vitamins, calcium, iron and protein for all the fat you’re taking in.
A medium order of French fries, on the other hand, provides you with almost 400 calories that are made almost exclusively from carbs and fats -26% of your daily fat intake, in fact. While it’s not mentioned here, French fries also provide 12% of your daily sodium intake and practically no vitamins or nutrients.
While French fries might be delicious and are acceptable as an occasional treat, a quick look at this infographic can help remind you that apple slices, a salad or just about any other side make for much healthier sides with your burger.

I wanted to share this photo I took because it depicts a nice example of providing passive value.
Coming up with the idea and adding this wall art required a one-time investment of time and energy. But once it’s shared, it can continue to provide value in the form of laughter and amusing conversations for visitors year after year.
Could this be monetized? Indirectly, sure. It could potentially cause more guys to talk about it… or to encourage their friends to use this restroom because of the silly surprise inside. Outside this restroom are several restaurants, and it’s just down the hall from a big casino, which offers plenty of opportunities to spend money.
If you’re curious to know, this restroom is located inside the Las Vegas Hotel (formerly known as the Las Vegas Hilton), next to their conference center. This would be one of the main restrooms used by convention-goers.
A common mistake people make in trying to creating passive income streams is that they focus on monetizing before they have anything to monetize. This is like fishing in a dry riverbed. It’s wasted energy. And people do this ALL THE TIME!
I dare say that most of the passive income failure stories I hear involve people trying to monetize a non-existent value stream. They try to go straight for the money, and their results are predictably weak. They’re doing the business equivalent of begging, and so they generally earn no more than beggars do.
You can’t produce a stream of passive income until you’ve have a stream of passive value, just as you can’t catch fish until you’ve found some water where fish are swimming.
Focus on creating the value stream first. Then when you know you have a healthy stream going, you can work on monetizing it.
If you focus on monetization first and foremost, that’s equivalent to saying, “Where are all the frakkin fish? Maybe some are hiding behind these cacti… or perhaps under that boulder. There must be some fish around here somewhere. Dammit, I paid good money for this fishing rod. Now, fish, listen up! I hereby command thee… come out from your hiding places, and skewer yourselves upon my hook!”
Stupid as this sounds, this is pretty much what people do when they get all gung ho about passive income with nary a concern for passive value.
Once you’ve integrated the mindset of creating passive value, and it feels like second nature to you, then you can think about monetizing earlier because you’ll know where to look for monetization opportunities. But until that becomes a habit, I encourage you to think deliberately about creating passive value streams first, before you give any thought to monetizing them. Get good at finding water first. Then work on your fishing skills.
My challenge to you now is to do something simple that can provide some passive value for others. Remember that even a photograph can do that. Where can you share this little piece of value such that a year from now, people might still be receiving the value you provided? Don’t worry about monetizing it. Just put something out there for free. Make it so.
How do you know if you’re really providing value? Feedback. Your attempt is only a guess. Other people are the ultimate judges of whether or not you provided value to them.
When I saw the men’s restroom mentioned above, I laughed and smiled. I snapped a photo. I shared it. For me this provided some value. If it does that for a lot of other people too, then whoever created this did a good job of creating a passive value stream.
If you do something that you believe will make people laugh, and no one laughs, then you didn’t provide value. You didn’t create the stream. That’s okay. It happens. In your attempts to provide value, you’ll often miss.
There is a skill element to value creation. It takes time to discern what people receive and appreciate as value, and it takes time to adjust your aim. I’m sure I’ve written many articles that few people cared about. But this helped me get better at understanding what people desire and how that matches up with what I can provide.
The more you condition this habit of looking for ways to create and provide passive value to others, the easier it will be for you to enjoy streams of passive income.
I wonder what the women’s restroom looks like…

The following is an excerpt from the appendices of The 4-Hour Body, which explores a common question: Can self-experimentation be valid at all, compared to placebo-controlled studies?
As we shall see, self-experimentation need not be extreme (I do the extremes so you don’t have to), and you can make significant discoveries with a sample size of one.
I’ll let a professional, Dr. Seth Roberts, explain how…
“All life is an experiment. The more experiments you make the better.” —Ralph Waldo Emerson
“It doesn’t matter how beautiful your theory is, it doesn’t matter how smart you are. If it doesn’t agree with experiment, it’s wrong.” —Richard Feynman
This is an excerpt from The 4-Hour Body, written by Dr. Seth Roberts, professor emeritus of psychology at the University of California–Berkeley and professor of psychology at Tsinghua University. His work has appeared in the New York Times Magazine and The Scientist, and he is on the editorial board of the journal Nutrition.

I started self-experimentation when I was a grad student. I was studying experimental psychology; self-experimentation was a way to learn how to do experiments.
One of my first self-experiments was about acne. My dermatologist had prescribed tetracycline, an antibiotic. Just for practice, I did an experiment to measure its effect. I varied the dosage of tetracycline—the number of pills per day—and counted the number of pimples on my face each morning. First I compared six pills per day (a high dose) and four pills per day (the prescribed dose). Somewhat to my surprise, they produced the same number of pimples. I tried other dosages. Eventually I tried zero pills per day. To my shock, zero pills per day produced the same number of pimples as four or six pills per day. The conclusion was unavoidable: the drug had no effect. (Many years later, research articles about antibiotic-resistant acne began to appear.) Tetracycline is a prescription drug; it’s not completely safe. I’d been taking it for months.
My dermatologist had also prescribed benzoyl peroxide, which comes in a cream. When my self-experimentation started, I believed that tetracycline was powerful and benzoyl peroxide weak, so I rarely used the cream. One day I ran low on tetracycline. Better use the cream, I thought. For the first time, I used the cream regularly. Again I was shocked: it worked well. Two days after I started using it, the number of pimples clearly went down. When I stopped the cream, two days later the number of pimples rose. When I restarted the cream, the number of pimples went down again.
My data left no doubt that (a) tetracycline didn’t work and (b) benzoyl peroxide did work—the opposite of my original beliefs. My dermatologist thought both worked. He’d seen hundreds of acne patients and had probably read hundreds of articles about acne. Yet in a few months I’d learned something important he didn’t know.
This wasn’t the usual line about self-experimentation. Read any book about it, such as Lawrence Altman’s Who Goes First? The Story of Self-Experimentation in Medicine, and you will come away thinking that self-experimentation is done by selfless doctors to test new and dangerous treatments. My experience was different. I wasn’t a doctor. I wasn’t trying to help someone else. I didn’t test a dangerous new treatment. Unlike the better-known sort of self-experimentation, which usually confirms what the experimenter believes, my self-experiments had shown I was wrong.
From my acne research I learned that self-experimentation can be used by non-experts to (a) see if the experts are right and (b) learn something they don’t know. I hadn’t realized such things were possible. The next problem I tried to solve this way was early awakening. For years, starting in my twenties, I woke up early in the morning, such as 4 a.m., still tired but unable to go back to sleep. Only a few dreary hours later would I be able to fall back asleep. This happened about half of all mornings. It showed no sign of going away. I didn’t want to take a pill for the rest of my life—not that there are any good pills for this—so I didn’t bother seeing a doctor. The only hope for a good solution, as far as I could tell, was self-experimentation.
So I did two things:
I recorded a few details about my sleep. The main one was whether I fell back asleep after getting up. How often this happened was my measure of the severity of the problem. In the beginning, I couldn’t fall back asleep about half of all mornings.I tested possible solutions.
The first thing I tried was aerobic exercise. It didn’t help. Early awakening was just as common after a day with exercise as after a day without exercise. I tried eating cheese in the evening. It didn’t help. I tried several more possible remedies.
None helped. After several years, I ran out of things to try. All my ideas about what might help had proved wrong.
Yet I managed to make progress. For unrelated reasons, I changed my breakfast from oatmeal to fruit. A few days later, I started waking up too early every morning instead of half the time. The problem was now much worse. This had never happened before. I recorded the breakfast change on the same piece of paper I used to keep track of my sleep, so the correlation was easy to see. To make sure the correlation reflected causality, I went back and forth between fruit and oatmeal. The results showed it was cause and effect. Fruit for breakfast caused more early awakening than oatmeal for breakfast. After ten years when nothing I’d done had made a difference, this was a big step forward. I eventually figured out that any breakfast made early awakening more likely. A long experiment confirmed this. The best breakfast was no breakfast.
I was less surprised than you might think. I knew that in a wide range of animals, including rats, a laboratory result called anticipatory activity is well established. If you feed a rat every day at the same time, it will become active about three hours earlier. If you feed it at noon, it will become active about 9 a.m. I had been eating breakfast at about 7 a.m. and waking up about 4 a.m. I had essentially found that humans were like other animals in this regard.
Not eating breakfast reduced early awakening but didn’t eliminate it. In the following years, self-experimentation taught me more about what caused it. By accident, I found that standing helped. If I stood more than eight hours in a day, I slept better that night. That wasn’t practical—after trying to stand that much for several years, I gave up—but the realization helped me make another accidental discovery 10 years later: standing on one leg to exhaustion helps. If I do this four times (left leg twice, right leg twice) during a day, even in the morning, I sleep much better that night. More recently, I’ve found that animal fat makes me sleep better.
Both effects are dose-dependent. I can get great sleep if I stand enough and great sleep if I eat enough animal fat.
How much animal fat is “enough”? I’ve just started trying to figure this out using pig fat, which I consume in a cut called pork belly (the part of the pig used for bacon). I found that 150 grams of pork belly had a little effect; 250 grams of pork belly had a much clearer effect. The effect seems to get larger with more pork belly (e.g., 350 grams). Because pork belly may be more than 90% fat by calories (there is great variation from one piece to the next), it’s a lot of calories of fat to get the maximum possible effect. I need to burn a lot of calories per day to make that many calories easy to eat, but it’s in some respects more convenient than standing on one foot.
Acne and sleep were my first self-experimental topics. Later I studied mood, weight control, and the effects of omega-3 on brain function. I learned that self-experimentation has three uses:
To test ideas. I tested the idea that tetracycline helps acne. I tested ideas about how to sleep better. And I’ve tested ideas derived from surprises. A few years ago, while trying to put on my shoes standing up, I realized my balance was much better than usual. I’d been putting on my shoes standing up for more than a year; that morning it was much easier than usual. The previous evening I’d swallowed six flaxseed-oil capsules. I did self-experiments to test the idea that flaxseed oil improves balance. (It did.)To generate new ideas. By its nature, self-experimentation involves making sharp changes in your life: you don’t do X for several weeks, then you do X for several weeks. This, plus the fact that we monitor ourselves in a hundred ways, makes it easy for self-experimentation to reveal unexpected side effects. This has happened to me five times. Moreover, daily measurements—of acne, sleep, or anything else—supply a baseline that makes it even easier to see unexpected changes.To develop ideas. That is, to determine the best way to use a discovery and to learn about the underlying mechanism. After I found that flaxseed oil improved balance, I used self-experimentation to figure out the best dose (three to four tablespoons per day).
One complaint about self-experimentation is that you’re not “blind.” Maybe the treatment works because you expect it to work. A placebo effect. I have never seen a case where this appeared to have happened. When treatment 10 helps after treatments 1 through 9 have failed to help (my usual experience), it’s unlikely to be a placebo effect. Accidental discoveries cannot be placebo effects.
My experience has shown that improve-your-life self-experimentation is remarkably powerful. I wasn’t an expert in anything I studied—I’m not a sleep expert, for example—but I repeatedly found useful cause-and-effect relationships (breakfast causes early awakening, flaxseed oil improves balance, etc.) that the experts had missed. This isn’t supposed to happen, of course, but it made a lot of sense. My self-experimentation had three big advantages over conventional research done by experts:
More power. Self-experiments are far better at determining causality (does X cause Y?) than conventional experiments. Obviously they’re much faster and cheaper. If I have an idea about how to sleep better, I can test it on myself in a few weeks for free. Conventional sleep experiments take a year or more (getting funding takes time) and cost thousands of dollars. A less obvious advantage of self-experimentation is that more wisdom is acquired. We learn from our mistakes. Fast self-experimentation means you make more mistakes. One lesson I learned stands out: Always do the minimum—the simplest, easiest experiment that will make progress. Few professional scientists seem to know this. Finally, as I mentioned earlier, self-experimentation is much more sensitive to unexpected side effects.Stone Age–like treatments are easy to test. I repeatedly found that simple environmental changes, such as avoiding breakfast and standing more, had big and surprising benefits. In each case, the change I’d made resembled a return to Stone Age life, when no one ate breakfast and everyone stood a lot. There are plenty of reasons to think that many common health problems, such as diabetes, high blood pressure, and cancer, are caused by differences between modern life and Stone Age life. Modern life and Stone Age life differ in many ways, of course; the fraction of differences that influence our health is probably low. If so, to find aspects of Stone Age life that matter, you have to do many tests. Self-experiments, fast and cheap, can do this; conventional experiments, slow and expensive, cannot. In addition, conventional research is slanted toward treatments that can make money for someone. Because conventional research is expensive, funding is needed. Drug companies will fund research about drugs, so lots of conventional research involves drugs. Elements of Stone Age life (such as no breakfast) are cheap and widely available. No company will fund research about their effectiveness.Better motivation. I studied my sleep for 10 years before making clear progress. That sort of persistence never happens in conventional health research. The reason is a difference in motivation. Part of the difference is how much the researcher cares about finding solutions. When you study your own problem (e.g., acne), you care more about finding a solution than others are likely to care. Acne researchers rarely have acne. And part of the motivation difference is the importance of goals other than solving the problem. When I studied my sleep, my only goal was to sleep better. Professional scientists have other goals, which are enormously constraining.
One set of prison bars involves employment and research funding. To keep their jobs (e.g., get tenure, get promoted, get jobs for their students, and get grants), professional scientists must publish several research papers per year. Research that can’t provide this is undoable. Another set of prison bars involves status. Professional scientists derive most of their status from their job. When they have a choice, they try to enhance or protect their status. Some sorts of research have more status than others. Large grants have more status than small grants, so professional scientists prefer expensive research to cheap research. High-tech has more status than low-tech, so they prefer high-tech. As Thorstein Veblen emphasized in The Theory of the Leisure Class (1899), useless research has higher status than useful research. Doing useless work, Veblen said, shows that you are higher-status than those who must do useful work. So researchers prefer useless research, thus the term “ivory tower.” Fear of loss of job, grant, or status also makes it hard for professional scientists to propose radical new ideas. Self-experimenters, trying to solve their own problem on their own time, are not trapped like this.
Acne illustrates the problem. The dermatological party line is that diet doesn’t cause acne. According to a website of the American Academy of Dermatology, “extensive scientific studies” show it’s a “myth” that “acne is caused by diet.” According to “guidelines for care” for dermatologists published in 2007, “dietary restriction (either specific foods or food classes) has not been demonstrated to be of benefit in the treatment of acne.” In fact, there is overwhelming evidence linking diet and acne. Starting in the 1970s, a Connecticut doctor named William Danby collected evidence connecting dairy consumption and acne; it is telling that Danby wasn’t a professional scientist. When his patients gave up dairy, it often helped. In 2002, six scientists (none a dermatologist) published a paper with the Weston Price–like conclusion that two isolated groups of people (Kitava Islanders and Ache hunter-gatherers) had no acne at all. They had examined more than 1,000 subjects over the age of 10 and found no acne. When people in these groups left their communities and ate differently, they did get acne. These observations suggest that a lot of acne—maybe all of it—can be cured and prevented by diet.
Why is the official line so wrong? Because the painstaking research needed to show the many ways diet causes acne is the sort of research that professional researchers can’t do and don’t want to do. They can’t do it because the research would be hard to fund (no one makes money when patients avoid dairy) and because the trial and error required would take too long per publication. They don’t want to do it because it would be low-tech, low-cost, and very useful—and therefore low-status. While research doctors in other specialties study high-tech expensive treatments, they would be doing low-cost studies of what happens when you avoid certain foods. Humiliating. Colleagues in other specialties might make fun of them. To justify their avoidance of embarrassment, the whole profession tells the rest of us, based on “extensive scientific studies,” that black is white. Self-experimentation allows acne sufferers to ignore the strange claims of dermatologists, not to mention their dangerous drugs (such as Accutane). Persons with acne can simply change their diets until they figure out what foods cause the problem.
Gregor Mendel was a monk. He was under no pressure to publish; he could say whatever he wanted about horticulture without fear for his job. Charles Darwin was wealthy. He had no job to lose. He could write On the Origin of Species very slowly. Alfred Wegener, who proposed continental drift, was a meteorologist. Geology was a hobby of his. Because they had total freedom and plenty of time, and professional biologists and geologists did not (just as now), Mendel, Darwin, and Wegener were able to use the accumulated knowledge of their time better than the professionals. The accumulated knowledge of our time is more accessible than ever before. Self-experimenters, with total freedom, plenty of time, and easy access to empirical tests, are in a great position to take advantage of it.

I started self-experimentation when I was a grad student. I was studying experimental psychology; self-experimentation was a way to learn how to do experiments.
One of my first self-experiments was about acne. My dermatologist had prescribed tetracycline, an antibiotic. Just for practice, I did an experiment to measure its effect. I varied the dosage of tetracycline—the number of pills per day—and counted the number of pimples on my face each morning. First I compared six pills per day (a high dose) and four pills per day (the prescribed dose). Somewhat to my surprise, they produced the same number of pimples. I tried other dosages. Eventually I tried zero pills per day. To my shock, zero pills per day produced the same number of pimples as four or six pills per day. The conclusion was unavoidable: the drug had no effect. (Many years later, research articles about antibiotic-resistant acne began to appear.) Tetracycline is a prescription drug; it’s not completely safe. I’d been taking it for months.
My dermatologist had also prescribed benzoyl peroxide, which comes in a cream. When my self-experimentation started, I believed that tetracycline was powerful and benzoyl peroxide weak, so I rarely used the cream. One day I ran low on tetracycline. Better use the cream, I thought. For the first time, I used the cream regularly. Again I was shocked: it worked well. Two days after I started using it, the number of pimples clearly went down. When I stopped the cream, two days later the number of pimples rose. When I restarted the cream, the number of pimples went down again.
My data left no doubt that (a) tetracycline didn’t work and (b) benzoyl peroxide did work—the opposite of my original beliefs. My dermatologist thought both worked. He’d seen hundreds of acne patients and had probably read hundreds of articles about acne. Yet in a few months I’d learned something important he didn’t know.
This wasn’t the usual line about self-experimentation. Read any book about it, such as Lawrence Altman’s Who Goes First? The Story of Self-Experimentation in Medicine, and you will come away thinking that self-experimentation is done by selfless doctors to test new and dangerous treatments. My experience was different. I wasn’t a doctor. I wasn’t trying to help someone else. I didn’t test a dangerous new treatment. Unlike the better-known sort of self-experimentation, which usually confirms what the experimenter believes, my self-experiments had shown I was wrong.
From my acne research I learned that self-experimentation can be used by non-experts to (a) see if the experts are right and (b) learn something they don’t know. I hadn’t realized such things were possible. The next problem I tried to solve this way was early awakening. For years, starting in my twenties, I woke up early in the morning, such as 4 a.m., still tired but unable to go back to sleep. Only a few dreary hours later would I be able to fall back asleep. This happened about half of all mornings. It showed no sign of going away. I didn’t want to take a pill for the rest of my life—not that there are any good pills for this—so I didn’t bother seeing a doctor. The only hope for a good solution, as far as I could tell, was self-experimentation.
So I did two things:
I recorded a few details about my sleep. The main one was whether I fell back asleep after getting up. How often this happened was my measure of the severity of the problem. In the beginning, I couldn’t fall back asleep about half of all mornings.I tested possible solutions.
The first thing I tried was aerobic exercise. It didn’t help. Early awakening was just as common after a day with exercise as after a day without exercise. I tried eating cheese in the evening. It didn’t help. I tried several more possible remedies.
None helped. After several years, I ran out of things to try. All my ideas about what might help had proved wrong.
Yet I managed to make progress. For unrelated reasons, I changed my breakfast from oatmeal to fruit. A few days later, I started waking up too early every morning instead of half the time. The problem was now much worse. This had never happened before. I recorded the breakfast change on the same piece of paper I used to keep track of my sleep, so the correlation was easy to see. To make sure the correlation reflected causality, I went back and forth between fruit and oatmeal. The results showed it was cause and effect. Fruit for breakfast caused more early awakening than oatmeal for breakfast. After ten years when nothing I’d done had made a difference, this was a big step forward. I eventually figured out that any breakfast made early awakening more likely. A long experiment confirmed this. The best breakfast was no breakfast.
I was less surprised than you might think. I knew that in a wide range of animals, including rats, a laboratory result called anticipatory activity is well established. If you feed a rat every day at the same time, it will become active about three hours earlier. If you feed it at noon, it will become active about 9 a.m. I had been eating breakfast at about 7 a.m. and waking up about 4 a.m. I had essentially found that humans were like other animals in this regard.
Not eating breakfast reduced early awakening but didn’t eliminate it. In the following years, self-experimentation taught me more about what caused it. By accident, I found that standing helped. If I stood more than eight hours in a day, I slept better that night. That wasn’t practical—after trying to stand that much for several years, I gave up—but the realization helped me make another accidental discovery 10 years later: standing on one leg to exhaustion helps. If I do this four times (left leg twice, right leg twice) during a day, even in the morning, I sleep much better that night. More recently, I’ve found that animal fat makes me sleep better.
Both effects are dose-dependent. I can get great sleep if I stand enough and great sleep if I eat enough animal fat.
How much animal fat is “enough”? I’ve just started trying to figure this out using pig fat, which I consume in a cut called pork belly (the part of the pig used for bacon). I found that 150 grams of pork belly had a little effect; 250 grams of pork belly had a much clearer effect. The effect seems to get larger with more pork belly (e.g., 350 grams). Because pork belly may be more than 90% fat by calories (there is great variation from one piece to the next), it’s a lot of calories of fat to get the maximum possible effect. I need to burn a lot of calories per day to make that many calories easy to eat, but it’s in some respects more convenient than standing on one foot.
Acne and sleep were my first self-experimental topics. Later I studied mood, weight control, and the effects of omega-3 on brain function. I learned that self-experimentation has three uses:
To test ideas. I tested the idea that tetracycline helps acne. I tested ideas about how to sleep better. And I’ve tested ideas derived from surprises. A few years ago, while trying to put on my shoes standing up, I realized my balance was much better than usual. I’d been putting on my shoes standing up for more than a year; that morning it was much easier than usual. The previous evening I’d swallowed six flaxseed-oil capsules. I did self-experiments to test the idea that flaxseed oil improves balance. (It did.)To generate new ideas. By its nature, self-experimentation involves making sharp changes in your life: you don’t do X for several weeks, then you do X for several weeks. This, plus the fact that we monitor ourselves in a hundred ways, makes it easy for self-experimentation to reveal unexpected side effects. This has happened to me five times. Moreover, daily measurements—of acne, sleep, or anything else—supply a baseline that makes it even easier to see unexpected changes.To develop ideas. That is, to determine the best way to use a discovery and to learn about the underlying mechanism. After I found that flaxseed oil improved balance, I used self-experimentation to figure out the best dose (three to four tablespoons per day).
One complaint about self-experimentation is that you’re not “blind.” Maybe the treatment works because you expect it to work. A placebo effect. I have never seen a case where this appeared to have happened. When treatment 10 helps after treatments 1 through 9 have failed to help (my usual experience), it’s unlikely to be a placebo effect. Accidental discoveries cannot be placebo effects.
My experience has shown that improve-your-life self-experimentation is remarkably powerful. I wasn’t an expert in anything I studied—I’m not a sleep expert, for example—but I repeatedly found useful cause-and-effect relationships (breakfast causes early awakening, flaxseed oil improves balance, etc.) that the experts had missed. This isn’t supposed to happen, of course, but it made a lot of sense. My self-experimentation had three big advantages over conventional research done by experts:
More power. Self-experiments are far better at determining causality (does X cause Y?) than conventional experiments. Obviously they’re much faster and cheaper. If I have an idea about how to sleep better, I can test it on myself in a few weeks for free. Conventional sleep experiments take a year or more (getting funding takes time) and cost thousands of dollars. A less obvious advantage of self-experimentation is that more wisdom is acquired. We learn from our mistakes. Fast self-experimentation means you make more mistakes. One lesson I learned stands out: Always do the minimum—the simplest, easiest experiment that will make progress. Few professional scientists seem to know this. Finally, as I mentioned earlier, self-experimentation is much more sensitive to unexpected side effects.Stone Age–like treatments are easy to test. I repeatedly found that simple environmental changes, such as avoiding breakfast and standing more, had big and surprising benefits. In each case, the change I’d made resembled a return to Stone Age life, when no one ate breakfast and everyone stood a lot. There are plenty of reasons to think that many common health problems, such as diabetes, high blood pressure, and cancer, are caused by differences between modern life and Stone Age life. Modern life and Stone Age life differ in many ways, of course; the fraction of differences that influence our health is probably low. If so, to find aspects of Stone Age life that matter, you have to do many tests. Self-experiments, fast and cheap, can do this; conventional experiments, slow and expensive, cannot. In addition, conventional research is slanted toward treatments that can make money for someone. Because conventional research is expensive, funding is needed. Drug companies will fund research about drugs, so lots of conventional research involves drugs. Elements of Stone Age life (such as no breakfast) are cheap and widely available. No company will fund research about their effectiveness.Better motivation. I studied my sleep for 10 years before making clear progress. That sort of persistence never happens in conventional health research. The reason is a difference in motivation. Part of the difference is how much the researcher cares about finding solutions. When you study your own problem (e.g., acne), you care more about finding a solution than others are likely to care. Acne researchers rarely have acne. And part of the motivation difference is the importance of goals other than solving the problem. When I studied my sleep, my only goal was to sleep better. Professional scientists have other goals, which are enormously constraining.
One set of prison bars involves employment and research funding. To keep their jobs (e.g., get tenure, get promoted, get jobs for their students, and get grants), professional scientists must publish several research papers per year. Research that can’t provide this is undoable. Another set of prison bars involves status. Professional scientists derive most of their status from their job. When they have a choice, they try to enhance or protect their status. Some sorts of research have more status than others. Large grants have more status than small grants, so professional scientists prefer expensive research to cheap research. High-tech has more status than low-tech, so they prefer high-tech. As Thorstein Veblen emphasized in The Theory of the Leisure Class (1899), useless research has higher status than useful research. Doing useless work, Veblen said, shows that you are higher-status than those who must do useful work. So researchers prefer useless research, thus the term “ivory tower.” Fear of loss of job, grant, or status also makes it hard for professional scientists to propose radical new ideas. Self-experimenters, trying to solve their own problem on their own time, are not trapped like this.
Acne illustrates the problem. The dermatological party line is that diet doesn’t cause acne. According to a website of the American Academy of Dermatology, “extensive scientific studies” show it’s a “myth” that “acne is caused by diet.” According to “guidelines for care” for dermatologists published in 2007, “dietary restriction (either specific foods or food classes) has not been demonstrated to be of benefit in the treatment of acne.” In fact, there is overwhelming evidence linking diet and acne. Starting in the 1970s, a Connecticut doctor named William Danby collected evidence connecting dairy consumption and acne; it is telling that Danby wasn’t a professional scientist. When his patients gave up dairy, it often helped. In 2002, six scientists (none a dermatologist) published a paper with the Weston Price–like conclusion that two isolated groups of people (Kitava Islanders and Ache hunter-gatherers) had no acne at all. They had examined more than 1,000 subjects over the age of 10 and found no acne. When people in these groups left their communities and ate differently, they did get acne. These observations suggest that a lot of acne—maybe all of it—can be cured and prevented by diet.
Why is the official line so wrong? Because the painstaking research needed to show the many ways diet causes acne is the sort of research that professional researchers can’t do and don’t want to do. They can’t do it because the research would be hard to fund (no one makes money when patients avoid dairy) and because the trial and error required would take too long per publication. They don’t want to do it because it would be low-tech, low-cost, and very useful—and therefore low-status. While research doctors in other specialties study high-tech expensive treatments, they would be doing low-cost studies of what happens when you avoid certain foods. Humiliating. Colleagues in other specialties might make fun of them. To justify their avoidance of embarrassment, the whole profession tells the rest of us, based on “extensive scientific studies,” that black is white. Self-experimentation allows acne sufferers to ignore the strange claims of dermatologists, not to mention their dangerous drugs (such as Accutane). Persons with acne can simply change their diets until they figure out what foods cause the problem.
Gregor Mendel was a monk. He was under no pressure to publish; he could say whatever he wanted about horticulture without fear for his job. Charles Darwin was wealthy. He had no job to lose. He could write On the Origin of Species very slowly. Alfred Wegener, who proposed continental drift, was a meteorologist. Geology was a hobby of his. Because they had total freedom and plenty of time, and professional biologists and geologists did not (just as now), Mendel, Darwin, and Wegener were able to use the accumulated knowledge of their time better than the professionals. The accumulated knowledge of our time is more accessible than ever before. Self-experimenters, with total freedom, plenty of time, and easy access to empirical tests, are in a great position to take advantage of it.
