The story of MSG is a true tragedy. The negativity associated with this delicious amino acid is due to a spurious study from 1968 that linked MSG with the “Chinese Restaurant Syndrome.” This study connected that gut-bomb feeling you sometimes get after eating Chinese food to MSG, despite the fact that the typically cheap Chinese food prepared in American restaurants is fatty and served in large portions, and (like any restaurant), the food can be spoiled. My mom theorizes that lots of MSG was used to cover up the fact that, say, shrimp was a day past its prime, and that the sick feeling was due to the food but got blamed on the MSG. There’s never been a scientifically rigorous study that’s linked MSG with any negative effects. MSG should be used frequently and added to anything that needs the flavor drawn out, especially soups. But it enhances virtually anything it touches: Once, eating pizza at home, a friend scanned my spice rack and saw a jar with white powder whose label, in my grandfather’s messy scrawl, read what looked like “MS6.” He sprinkled it on his pizza and came to find me, telling me that whatever MS6 was, it was the most amazing thing he’d ever tasted. Yes, MSG makes even pizza better.

QotD: Veganism has its drawbacks
Evangelical vegans will tell you that following a purely ‘plant-based’ diet is not only morally commendable, it’s also much better for your health. But if my experience is anything to go by, the opposite is true.
I felt absolutely fine for the first few days. I didn’t miss meat at all, certainly not in terms of taste or flavour. The only thing I really felt an absence of was eggs. Since I embarked on my mammoth weight-loss project, eggs have become a dietary staple for me: nothing fills me up as well or gives me quite as much long-lasting energy as an egg.
I also found I had to eat larger portions to feel full — and I felt hungry again after a shorter period of time. But even that didn’t bother me, since what I was eating was so wholesome.
No, the real issue became apparent after the third or fourth day. Not to put too fine a point on it: wind.
My stomach was, quite literally, in ferment. All those legumes and pulses and generalised vegetable matter appeared to have turned into a giant internal compost heap. It wasn’t too bad in the mornings; but by early afternoon I was like a cow who had overdosed on clover.
At first, I palmed the outcome off on our three dogs. But after a while the problem became so severe that even they could not be expected to account for the frequency and potency of aromas emerging from my lower digestive tract.
One of the key arguments of vegans against livestock farming is the harm animals cause to the planet through the amount of methane they produce; if my experience was anything to go by, a vegan human is capable of producing just as much, if not more. I was a one-woman global warming hazard.
My children, of course, thought it was hilarious. But from my point of view, it was not only unpleasant and occasionally embarrassing, it was also incredibly uncomfortable. I felt bloated, soggy and sluggish, and began to dread meal times.
Following the advice of the nutritionist, I took to soaking nuts, oats and seeds overnight. But it made no difference. If anything, the problem began to get worse. The more healthy vegan food I put into my body, the worse my stomach problems became.
As for the much-vaunted ‘vegan glow’, no sign. Instead, my skin felt dry and dehydrated, and there was a distinctly greyish tinge to my complexion. But still, I persisted.

James May’s Things You Need To Know – Series 2 – Episode 5 – Engineering (S02E05)
Uninsulated Crimp
Published on 10 Apr 2013James May gives a straightforward guide to some of science’s big ideas, explaining everything from evolution and Einstein to engineering and chemistry.
The not-so-ancient extinction of Madagascar’s megafauna
At The Conversation, Nick Scroxton, Laurie Godfrey, and Stephen Burns discuss their new theory on the megafauna extinction in Madagascar just over a thousand years ago:
Giant 10-foot-tall elephant birds, with eggs eight times larger than an ostrich’s. Sloth lemurs bigger than a panda, weighing in at 350 pounds. A puma-like predator called the giant fosa.
They sound like characters in a child’s fantasy book, but along with dozens of other species, they once really roamed the landscape of Madagascar. Then, after millions of years of evolution in the middle of the Indian Ocean, the populations crashed in just a couple of centuries.
Scientists know that over the past 40,000 years, most of Earth’s megafauna – that is, animals human-size or larger – have gone extinct. Woolly mammoths, sabre tooth tigers and countless others no longer roam the planet.
What’s remarkable about the megafaunal crash in Madagascar is that it occurred not tens of thousands of years ago but just over 1,000 years ago, between A.D. 700 and 1000. And while some small populations survived a while longer, the damage was done in a relatively short amount of time. Why?
Over the last three years, new investigations into climate and land use patterns, human genetic diversity on the island and the dating of hundreds of fossils have fundamentally changed scientists’ understanding of the human and natural history of Madagascar. As two paleoclimatologists and a paleontologist, we brought together this research with new evidence of megafaunal butchery. In doing so we’ve created a new theory of how, why and when these Malagasy megafauna went extinct.
Many of the forests that originally existed on Madagascar are now replaced by more open, human-modified landscapes, like this palm savanna at Anjohibe.

QotD: Organic spices are a racket
There’s a whole other piece to be written about organic spices, but the short version is that demanding organic spices is never going to be good for the farmers growing them. The U.S. standards for organic products amounts to ridiculously expensive and oftentimes unnecessary practices for small farmers who just don’t have the resources to do it. There are plenty of ways to arrive at ethical treatment of animals and land that are not part of our complicated organic laws. And that’s not to mention the people who demand organic products but will also freak out at the sight of a bug or won’t buy something that’s even a little bit misshapen or with a tiny brown spot on it. You can have pesticides or you can have pests.

QotD: Salt
My grandfather used to say this all the time, and it’s true. Salt brings out the flavor of the food, full stop. There are a great variety of salts, but the reality is they’re all the same mineral. Coloration in salt comes from the minerals near the salt as it forms. There’s nothing inherently better about colored salts, but the marketers selling you that stuff will try to convince you otherwise. I’ve seen pink salt promoted as an “alternative” salt that doesn’t cause blood pressure issues. That’s a lie. My advice is to buy kosher salt or the chunkier white salt if you like the crunchiness. If you really like the mild flavoring of gray salt, that’s fine, just know that it’s sold at a higher cost for what comes down to the same thing as my box of salt I can get for a couple bucks. And one more thing: All salt is sea salt.
Salt grinders are bullshit
I’m not done with salt yet: Don’t put your salt in a grinder. All you’re doing is making your salt smaller than it was before. Unlike pepper, which is actually processed in the grinder, salt does not need to be ground and is not fresher after coming out of a grinder. It’s just smaller. Use a shaker.

Trust in scientific findings decreasing among the general public
In Scientific American, Louise Lief discusses the problem of rising public distrust of science:
We live in a moment when preventable infectious diseases like measles are spreading because parents distrust vaccines, and scientists at government agencies are being told not to use terms like “evidence-based.” The president dismisses the findings of a National Climate Assessment by more than 300 scientists and 13 federal agencies that warns of massive economic and environmental damage totaling hundreds of billions of dollars, crop failures, disrupted supply chains and multiple threats to human health, saying, “I don’t believe it.”
But when I argued in favor of the proposition (Resolved: “Science writers are responsible for building public trust in science”) during a debate at the National Association of Science Writers’ 2018 annual conference last fall, the majority of science writers and science journalists present voted that building public trust in science was not the responsibility of science writers.
[…]
Kathleen Hall Jamieson, director of the Annenberg Public Policy Center at the University of Pennsylvania’s Annenberg School for Communication also tackled the science trust question at the NASW conference, and researchers at Cardiff University have traced credibility and accuracy problems to press releases from scientists’ own academic institutions.
If a problem is discovered or a study is retracted, said Jamieson, the scientist or scientific journal needs to explain to journalists and the public how the error was discovered, what the problem is, and what steps are being taken to ensure it doesn’t happen again.
Scientists often make it hard for journalists to cover these three interrelated issues, she says. Scholarly journal publication protocols may cause scientists to write one article on the problem they’re investigating, and a second or third article on processes and solutions, resulting in coverage that emphasizes problems and shortchanges corrective action.
For their part, researchers at Cardiff University found that press releases from scientists’ own academic institutions about their work were a significant source of exaggerated claims and spin, even though most scientists can approve their wording.
Their study of press releases from 20 leading British universities on health-related science news found that when the press releases exaggerated, it was likely the news stories would too.
An analysis of 41 news articles on randomized controlled trials based on 70 press releases showed only four articles that contained exaggerated claims not included in the press release or journal abstract. Interestingly, they also found the hype and spin intended to tempt the media did not result in more news coverage.

The NHS, Britain’s “national treasure”, gets panned by other EU patients who’ve experienced non-NHS care
In The Conversation, Chris Moreh, Athina Vlachantoni, and Derek McGhee report that — contrary to British myth-making — the National Health Service isn’t the envy of the civilized world:
Britain’s National Health Service is often described as a “national treasure”. And it is a sentiment those on the left and the right of the political divide agree on. The British public are so proud of the NHS, they made it the central theme of the opening ceremony of the 2012 London Olympic Games.
But this pride has also been coupled with fears that the universal healthcare provided by the NHS might be taken advantage of by patients from outside the UK. A few months after the Olympics, the then health secretary, Jeremy Hunt, felt the need to clarify that “we are a national health service, not an international health service”. The 2015 election-winning manifesto of the Conservative party made this point even clearer when it pledged to “tackle health tourism” and “recover up to £500m from migrants who use the NHS”.
But our research shows that while the NHS may be a national treasure to British people, EU migrants would rather be treated in their countries of origin. As a 38-year-old woman from Germany put it: “Sorry, NHS? No thanks.” And the reasons for rejecting the NHS? A 25-year-old man from the Netherlands says it’s because the “NHS is slow and the medical care mediocre”. Or, at least, it “is rather poor compared to healthcare in my country,” says a 45-year-old woman from Germany.
But why should British people worry about what EU migrants think of their health service? What EU migrants think and choose is important because they are familiar with at least two European healthcare systems. They have the information and personal experience that most British citizens do not. There is a lot to be learnt from them.

Debunking Stephen Jay Gould
Several years back, I linked to a David Friedman post on a study that contradicted a key argument in Stephen Jay Gould’s book The Mismeasure of Man. While I’ve read a few of his books, it’s been nearly 15 years since I last read anything by him … by now I only have a vague recollection of what he wrote, but his works were quite popular at the time. Much more recently Russell T. Warne looked at different problems in Gould’s work that are much more damaging to his reputation:
Stephen Jay Gould, the famous 20th century paleontologist, published his most celebrated work, The Mismeasure of Man, in 1981. Gould’s thesis is that throughout the history of science, prejudiced scientists studying human beings allowed their social beliefs to color their data collection and analysis. Gould believed that this confirmation bias was particularly powerful when a scientists’ beliefs were socially important to them. […] The Mismeasure of Man provides a great deal of evidence that scientists’ pre-existing beliefs color their judgment — but not in the way he intended. Rather, the book is a perfect example of the sin it purports to expose in others. Gould’s Marxist political beliefs made him attack intelligence research because he saw it as a threat to his egalitarian social goals. Ironically, it was this allegiance to ideology over data that made Gould himself a classic examplar of a biased scientist.
[…]
Most criticism of The Mismeasure of Man was confined to the recherché world of psychologists who study intelligence. However, a new debate opened up in 2011 when a team of anthropologists argued that Gould’s analysis of the data on cranium measurements from 19th century scientist Samuel George Morton was flawed. Gould cast Morton as a racist who fudged his data to match his beliefs about white racial superiority because of a supposed larger skull capacity. Instead, the anthropologists argued, it was Gould who manipulated the data to support his biases.
This ignited a series of follow-up articles in the scholarly literature by authors taking a variety of positions regarding Morton’s data and Gould’s interpretations. Weisberg believed that the re-analysis was flawed and Gould was mostly correct. Kaplan and his colleagues claimed that Morton’s interpretations were flawed, but that Gould was incorrect in believing that he could discern Morton’s actions and motivations. Finally, Mitchell believed that Morton’s data were accurate and that the interpretations were colored by the racism of the era, but the claim that Morton subtly manipulated the data was a fiction created by Gould.
Though still unresolved, the debate shows that a critical analysis of specific sections of The Mismeasure of Man is warranted. After writing an article about Lewis Terman, an important developer of early intelligence tests, I decided that a 23-page section of The Mismeasure of Man would be a valuable section of the book to analyze. This section is Gould’s description and analysis of the Army Beta test, one of the tests that Terman helped create. The Army Beta was used in World War I to screen illiterate recruits for military service.
Having read some of the primary scholarly work about the Army Beta, I knew that some of Gould’s claims were inaccurate. However, I was unprepared for the level of pervasive deception that I encountered when I carefully checked Gould’s claims against the historical record. Moreover, I discovered overwhelming evidence that any pretense of Gould being “objective” — even if defined as “fair treatment of data” — is a farce. In The Mismeasure of Man, Gould elevates his biases to the status of uncontestable facts and to great lengths to hide the truth from his readers.
Understanding the Great Depression
Marginal Revolution University
Published on 23 May 2017In this video, we examine the causes behind the Great Depression with the help of the aggregate demand-aggregate supply model.
In 1929, the stock market crashed and an air of pessimism swept across America — making bank depositors nervous. What would you do if you thought your money might not be safe with the bank? You’d probably want it back in your own hands. What happened next? A run on the banks.
Along with the Stock Market Crash of 1929, it’s one of the iconic moments of the early days of Great Depression. However, the Great Depression was an incredibly complex downturn in which the economy experienced a series of aggregate demand shocks. By the end of this video, you’ll walk away with a better understanding of the many factors behind the Great Depression and how to apply the AD-AS model to a real-world scenario.

I’ve mentioned before I’m more or less blind in one eye and this is almost definitely a result of a mutation in my family line. And you know, given the option, I’m not sure if I’d have it removed. Or, I’d need to give it a very, very long think.
There are plenty of lovely and bizarre anomalies specific to individuals, and it’s not for me to say – or even speculate really – where the line should be drawn when it comes to one day potentially making alterations to our descendants.

QotD: “Scientific” urban planning versus messy, unscientific, evolved town growth
Natural organically-evolved cities tend to be densely-packed mixtures of dark alleys, tiny shops, and overcrowded streets. Modern scientific rationalists came up with a better idea: an evenly-spaced rectangular grid of identical giant Brutalist apartment buildings separated by wide boulevards, with everything separated into carefully-zoned districts. Yet for some reason, whenever these new rational cities were built, people hated them and did everything they could to move out into more organic suburbs. And again, for some reason the urban planners got promoted, became famous, and spread their destructive techniques around the world.
Ye olde organically-evolved peasant villages tended to be complicated confusions of everybody trying to raise fifty different crops at the same time on awkwardly shaped cramped parcels of land. Modern scientific rationalists came up with a better idea: giant collective mechanized farms growing purpose-bred high-yield crops and arranged in (say it with me) evenly-spaced rectangular grids. Yet for some reason, these giant collective farms had lower yields per acre than the old traditional methods, and wherever they arose famine and mass starvation followed. And again, for some reason governments continued to push the more “modern” methods, whether it was socialist collectives in the USSR, big agricultural corporations in the US, or sprawling banana plantations in the Third World.
Traditional lifestyles of many East African natives were nomadic, involving slash-and-burn agriculture in complicated jungle terrain according to a bewildering variety of ad-hoc rules. Modern scientific rationalists in African governments (both colonial and independent) came up with a better idea – resettlment of the natives into villages, where they could have modern amenities like schools, wells, electricity, and evenly-spaced rectangular grids. Yet for some reason, these villages kept failing: their crops died, their economies collapsed, and their native inhabitants disappeared back into the jungle. And again, for some reason the African governments kept trying to bring the natives back and make them stay, even if they had to blur the lines between villages and concentration camps to make it work.
Why did all of these schemes fail? And more importantly, why were they celebrated, rewarded, and continued, even when the fact of their failure became too obvious to ignore? Scott gives a two part answer.
The first part of the story is High Modernism, an aesthetic taste masquerading as a scientific philosophy. The High Modernists claimed to be about figuring out the most efficient and high-tech way of doing things, but most of them knew little relevant math or science and were basically just LARPing being rational by placing things in evenly-spaced rectangular grids.
But the High Modernists were pawns in service of a deeper motive: the centralized state wanted the world to be “legible”, ie arranged in a way that made it easy to monitor and control. An intact forest might be more productive than an evenly-spaced rectangular grid of Norway spruce, but it was harder to legislate rules for, or assess taxes on.
The state promoted the High Modernists’ platitudes about The Greater Good as cover, in order to implement the totalitarian schemes they wanted to implement anyway. The resulting experiments were usually failures by the humanitarian goals of the Modernists, but resounding successes by the command-and-control goals of the state. And so we gradually transitioned from systems that were messy but full of fine-tuned hidden order, to ones that were barely-functional but really easy to tax.

The “grandmother hypothesis”
Jonathan Lambert on the theory for why, almost alone among species, human females live on well past their reproductive years:
Killer whales, Japanese aphids and Homo sapiens — they’re among the few organisms whose females live on long past the age of reproduction.
Since the name of the evolutionary game is survival and reproduction, the phenomenon begs explanation — why live longer than you can reproduce? In the 1960s, researchers came up with the “grandmother hypothesis” to explain the human side of things. The hypothesis is that the help of grandmothers enables mothers to have more children. So women who had the genetic makeup for longer living would ultimately have more grandchildren carrying their longevity genes. (Sorry, grandfathers, you’re not included in this picture.)
Two studies published Thursday in Current Biology take another look at this hypothesis and add new insights into the role grandmothers play.
The first hard evidence for the grandmother hypothesis was gathered by Kristen Hawkes, an anthropologist at the University of Utah who was studying the Hadza people, a group of hunter-gatherers in northern Tanzania. Hawkes was struck by “how productive these old ladies were” at foraging for food, and she later documented how their help allowed mothers to have more children.
If our long post-reproductive lives evolved because of grandmothers, we should be able to find fingerprints of the benefits of grandmothering in many cultures. But the circumstances of modern life differ drastically from those we faced at the beginning of our evolutionary story.
The studies in Current Biology turned to the detailed records of two preindustrial populations, one in what is now Quebec and the other in Finland. The researchers mined these rich databases to quantify the reproductive boost that grandmothers provide and to help us better understand the limits of their help.

QotD: Teaching evolution in the “Bible Belt”
I teach college in a small city in Arkansas, deep in the American Bible Belt. I am a historian of Africa and in my department that means that I also teach a world history survey. I always start with the expansion of modern humans out of Africa and their encounter with other types of humans: Neanderthals, Homo erectus, Denesovians and what seems like an ever-growing list of newly discovered human-like creatures. It’s less the case now, but when I started twenty years ago this part of the course was initially met with polite but firm resistance, which gradually gave way to a sort of furtive curiosity. I eventually realized that even my cleverest students knew very little about human evolution except that it was false and that they were supposed to reject it. They came to the university having been taught that evolution was part of a larger attack on their faith and values, but they had never really been exposed to anything but a sort of parody version of it. A small number of them accepted evolutionary theory, but being a Darwinian in rural Arkansas was usually more about youthful rebellion and non-conformity than it was about informed, rational consideration of evidence.
Once we got past the denunciation or acceptance of evolutionary theory as a form of tribal affiliation, I found students to be deeply curious about it. It was such a taboo subject that their high school teachers had only skimmed over it and often with some careful personal distancing from the material. So the opportunity to delve into the details of this forbidden knowledge was intellectually thrilling for them. Despite the excitement engendered by the topic only a few changed their minds; most did not.
My students had grown up in communities where evolutionary theory was so wrong, so contrary to the accepted worldview of all decent people, that the only acceptable way to talk about it was to denounce it or reject it. The result was that most of my students rejected evolution, but getting a chance to learn about it was profoundly exciting, even if most of them were too conformist (these were Honors students after all) to change their positions.
