I could watch these video clips (also here) all day. You may have learned about Doug Lemov from this NY Times Magazine article. The quote “without great teachers, nothing else matters” is from the website of the organization (Uncommon Schools) that Lemov founded. The clips show techniques he has isolated that great teachers use in elementary school.

My research is fundamentally about deficiency diseases. I find things present in Stone Age life but absent now whose absence causes problems. Sometimes I work backwards (from present to past): why am I not sleeping well? This turned out to have a Stone-Age-related answer. Sometimes I work forwards: I study something present in Stone-Age life but not now and learn it makes things better: standing (better sleep), morning faces (better mood).
So I know a lot about deficiency diseases. One curious thing about them is the opportunity they present. Without scurvy, we wouldn’t have discovered Vitamin C. Once we’ve discovered Vitamin C, we can figure out the optimal amount, possibly leaving us better off than before scurvy became a problem.

This is what I thought as I watched these clips. Formal education is unnatural. No wonder it’s so hard. These clips, however, show that with considerable understanding of psychology you can solve the problems it presents. And perhaps leave us better off than before formal schooling began.

Susan Allport, having written The Queen of Fats, unsurprisingly eats a diet high in omega-3 and low in omega-6. For one month, however, she ate a diet with more omega-6 and less omega-3 and wrote about it– like Supersize Me, except far more realistic.

O magazine commissioned a story about it but didn’t run it. “My weight gain was only 0.5 pounds and they thought their readers wouldn’t see the importance of that,” says Allport. Her draft is here. There were three striking changes over the month: the omega-6/omega-3 ratio in her blood doubled (implying that this ratio is controlled by diet rather than by stored fat); her belly fat noticeably increased; and the elasticity of her arteries decreased by 20%. This supports Allport’s belief (and mine) that omega-6 is dangerous when consumed in large amounts, as it is if you eat a lot of food cooked in vegetable oil.

The American Heart Association recommends that Americans eat more omega-6. The justification of this recommendation says nothing about the Israeli Paradox, which to me is the best reason to avoid a diet high in omega-6. Allport’s experience is another reason.
Allport is also the author of Explorers of the Black Box, about neuroscience research.

How strange:

In a striking departure from his political counterparts across the country, Saskatchewan Premier Brad Wall says his government will finance clinical trials of liberation therapy, a contentious experimental procedure for multiple sclerosis patients.

Of course, the heads of provinces don’t usually get involved in research at this level of detail. However, “Saskatchewan has the highest rate of MS in the country,” says the article.

In Part 5 of The Story of Science (BBC), Michael Mosley, the presenter, said that for hundreds of years medical students were shown a human liver and told it had three lobes. They were told that because that’s what Galen had said. However, human livers do not have three lobes. As the students could see. Mosely is a doctor. “When I was a medical student,” said Mosley, “there was tremendous pressure to conform.” MS researchers have said for a long time that MS is an autoimmune disease. Could this have been as misleading as Galen’s description of the liver?

At the end of a BookTV interview of Harry Markopolos, the guy who discovered Madoff’s Ponzi scheme, Markopolos says

No one’s going to care about you like [= as much as] you do.

He meant this as financial advice: Make up your own mind about how to invest your money. Don’t assume someone else has done the necessary thinking.

My self-experimentation led me to the same conclusion, as I wrote here. My self-experimentation uncovered helpful treatments (e.g., how to sleep better) that the experts (in this case, sleep researchers) had missed. I theorized that this was partly because I cared more than they did about the quality of my sleep. I had “the motivation of a person with the problem”; they didn’t.

• Correlation between sitting and mortality, equated for physical activity.
• Exercise and weight loss. I had a similar experience: After an extremely intense racquetball session, I lost 6-8 pounds over the next two weeks.
