Food labelling laws and craft brewing … not a match made in heaven

Filed under: Bureaucracy, Business, Health, USA — Tags: , — Nicholas @ 03:00

Eric Boehm on how well-intentioned laws can still have significant and unforeseen negative side-effects:

Brewers are facing the prospect of spending potentially thousands to determine calorie counts for every variety of beer produced. Unless they spend the money to provide the information, breweries may never get their products into chain restaurants, like Buffalo Wild Wings and Applebee’s.

As is often the case with regulations, smaller breweries stand to lose the most.

“A regional craft brewer or a major brewery can spread the cost over a much larger volume of sales and it’s not so unreasonable for them,” said Paul Gatza, a former brewer who now heads the Boulder, Colorado, based Brewers’ Association, an industry group.

“Smaller guys that are just trying to sell a keg or two here or there, they have a decision to make on whether it is worth the additional cost to try to get their beers into chain restaurants,” Gatza told Watchdog.

The Food and Drug Administration is in the process of finalizing menu labeling rules that were part of the Affordable Care Act. Intended to make Americans more aware of their dietary choices, the rules are subject to controversy on several fronts, and the FDA announced in September that implementation of the new rules would be pushed back one full year, until December 2016, as the feds try to work out the kinks.

My favourite local brewery isn’t even a micro-brewery (they’re somewhere between a pico- and a nano-brewery): every week when I drop in, there are three or four new batches ready to sample (and it’s rare that there’s anything left of last week’s offerings). If they had to spend hundreds or even thousands of dollars to comply with detailed labelling requirements for every small batch they brewed, they’d never stand a chance of making a profit. I understand the urge to ensure that people have a chance to avoid ingredients that might make them ill, but this is the sort of regulation that tilts very heavily toward the big companies that have regional or national markets. A thousand dollars per product isn’t even a drop in the bucket to them, while to a small local business, that might be more than their profit margin when you require it be done for everything they produce.

QotD: Investigating the reactionary view of racism

Filed under: Media, Quotations, Science — Tags: , , — Nicholas @ 01:00

Almost all of our hard data on race comes from sociology programs in universities – ie the most liberal departments in the most liberal institutions in the country. Most of these sociology departments have an explicit mission statement of existing to fight racism. Many sociologists studying race will tell you quite openly that they went into the field – which is not especially high-paying or prestigious – in order to help crusade against the evil of racism.

Imagine a Pfizer laboratory whose mission statement was to prove Pfizer drugs had no side effects, and whose staff all went into pharmacology specifically to help crusade against the evil of believing Pfizer’s drugs have side effects. Imagine that this laboratory hands you their study showing that the latest Pfizer drug has zero side effects, c’mon, trust us! Is there any way you’re taking that drug?

We know that a lot of medical research, especially medical research by drug companies, turns up the wrong answer simply through the file-drawer effect. That is, studies that turn up an exciting result everyone wants to hear get published, and studies that turn up a disappointing result don’t – either because the scientist never submits it to the journals, or because the journal doesn’t want to publish it. If this happens all the time in medical research despite growing safeguards to prevent it, how often do you think it happens in sociological research?

Do you think the average sociologist selects the study design most likely to turn up evidence of racist beliefs being correct, or the study design most likely to turn up the opposite? If despite her best efforts a study does turn up evidence of racist beliefs being correct, do you think she’s going to submit it to a major journal with her name on it for everyone to see? And if by some bizarre chance she does submit it, do you think the International Journal Of We Hate Racism So We Publish Studies Proving How Dumb Racists Are is going to cheerfully include it in their next edition?

And so when people triumphantly say “Modern science has completely disproven racism, there’s not a shred of evidence in support of it”, we should consider that exactly the same level of proof as the guy from 1900 who said “Modern science has completely proven racism, there’s not a shred of evidence against it”. The field is still just made of people pushing their own dogmatic opinions and calling them science; only the dogma has changed.

And although Reactionaries love to talk about race, in the end race is nothing more than a particularly strong and obvious taboo. There are taboos in history, too, and in economics, and in political science, and although they’re less obvious and interesting they still mean you need this same skepticism when parsing results from these fields. “But every legitimate scientist disagrees with this particular Reactionary belief!” should be said with the same intonation as “But every legitimate archbishop disagrees with this particular heresy.”

This is not intended as a proof that racism is correct, or even as the slightest shred of evidence for that hypothesis (although a lot of Reactionaries are, in fact, racist as heck). No doubt the Spanish Inquisition found a couple of real Satanists, and probably some genuine murderers and rapists got sent to Siberia. Sometimes, once in a blue moon, a government will even censor an idea that happens to be false. But it’s still useful to know when something is being censored, so you don’t actually think the absence of evidence for one side of the story is evidence of anything other than people on that side being smart enough to keep their mouths shut.

We’re in “a terrible, horrible, no good, very bad news cycle for Obamacare”

Filed under: Business, Health, USA — Tags: , — Nicholas @ 04:00

Megan McArdle on the plight of some health insurance companies as they try to offer healthcare policies and still make some sort of profit in the current American market:

… UnitedHealth abruptly said it expected to lose hundreds of millions of dollars on its exchange policies in 2015 and 2016, and would be assessing whether to pull out of the market altogether in the first half of next year.

This was part of a terrible, horrible, no good, very bad news cycle for Obamacare; as ProPublica journalist Charles Ornstein said on Twitter, “Not since 2013 have I seen such a disastrous stream of bad news headlines for Obamacare in one 24-hour stretch.” Stories included not just UnitedHealth’s dire warnings, but also updates in the ongoing saga of higher premiums, higher deductibles and smaller provider networks that have been coming out since open enrollment began.

It now looks pretty clear that insurers are having a very bad experience in these markets. The sizeable premium increases would have been even higher if insurers had not stepped up the deductibles and clamped down on provider networks. The future of Obamacare now looks like more money for less generous coverage than its architects had hoped in the first few years.

But of course, that doesn’t mean insurers need to leave the market. Insurance is priced based on expectations; if you expect to pay out more, you just raise the price. After all, people are required to buy the stuff, on pain of a hefty penalty. How hard can it be to make money in this market?

What UnitedHealth’s action suggests is that the company is not sure it can make money in this market at any price. Executives seem to be worried about our old enemy, the adverse selection death spiral, where prices go up and healthier customers drop out, which pushes insurers’ costs and customers’ prices up further, until all you’ve got is a handful of very sick people and a huge number of very expensive claims.

Some commentators, including me, worried a lot about death spirals in the early days of the disastrous exchange rollout. Some commentators, also including me, have eased off on those fears in recent years. Why the change? Because when the law was passed, I was mostly focused on whether the mandate penalty would be enough to encourage people to buy insurance. Over time, as the exchanges evolved, the subsidies, and the open enrollment limitations, started to look a lot more important than the penalty.


An earnings call like today’s can also be a bargaining tactic. Health insurers are engaged in a sort of perpetual negotiation with regulators over how much they’ll be allowed to charge, what sort of help they’ll get from the government if they lose money, and a thousand other things. Signaling that you’re willing to pull out of the market if you don’t get a better deal is a great way to improve your bargaining position with legislators and regulatory agencies.

That said, strategic positioning is obviously far from the whole story, or even the majority of it. UnitedHealth really is losing money on these policies right now. It really is seeing something that looks dangerously like adverse selection. And frankly, there’s not that much the company can get out of regulators at this point, because the Congressional Republicans have cut off the flow of funds. So while Obamacare certainly isn’t dead, or certain to spiral to its death, it’s got some very worrying symptoms.

Is a possible cure for old age now in sight?

Filed under: Health, Science — Tags: , , , — Nicholas @ 05:00

Matt Ridley on recent developments in the search for ways to ameliorate the effects of aging:

Squeezed between falling birth rates and better healthcare, the world population is getting rapidly older. Learning how to deal with that is one of the great challenges of this century. The World Health Organisation has just produced a report on the implications of an ageing population, which — inadvertently — reveals a dismal fatalism we share about the illnesses of old age: that they will always be inevitable.

This could soon be wrong. A new book, The Telomerase Revolution, published in America this week by the doctor and medical researcher Michael Fossel, argues that we now understand enough about the fundamental cause of ageing to be confident that we will eventually be able to reverse it. This would mean curing diseases such as Alzheimer’s, heart disease and osteoporosis, rather than coping with them or treating their symptoms.

Let me show you what I mean about fatalism. The WHO report on ageing and health, for all its talk of the need for “profound changes” to health care for the elderly, actually urges us to stop trying to cure the afflictions of old age and learn to live with them: “The societal response to population ageing will require a transformation of health systems that moves away from disease-based curative models and towards the provision of older-person-centred and integrated care.”

Yet it also subscribes to the somewhat magical hope that illnesses of old age can be “prevented or delayed by engaging in healthy behaviours” and that “physical activity and good nutrition can have powerful benefits for health and wellbeing.” This is largely wishful thinking. There is no evidence that, say, Alzheimer’s can be prevented by a certain diet or activity. A lack of activity and poor nutrition can worsen health at any age, but the underlying chronic diseases of old age are caused by age itself.

When I asked Dr Fossel what he thought of the WHO report, he replied: “In 1950 we could have talked (and did) about ‘active polio’ in the sense of keeping polio victims active rather than giving up, but the very phrase itself implies that one has already given up. I would prefer that we cure the fundamental problem. Why talk about ‘active ageing’, ‘successful ageing’, and ‘healthy ageing’ when we could talk about not ageing?”

QotD: The Great Filter

Filed under: Media, Quotations, Science, Space — Tags: , — Nicholas @ 01:00

The Great Filter, remember, is the horror-genre-adaptation of Fermi’s Paradox. All of our calculations say that, in the infinite vastness of time and space, intelligent aliens should be very common. But we don’t see any of them. We haven’t seen their colossal astro-engineering projects in the night sky. We haven’t heard their messages through SETI. And most important, we haven’t been visited or colonized by them.

This is very strange. Consider that if humankind makes it another thousand years, we’ll probably have started to colonize other star systems. Those star systems will colonize other star systems and so on until we start expanding at nearly the speed of light, colonizing literally everything in sight. After a hundred thousand years or so we’ll have settled a big chunk of the galaxy, assuming we haven’t killed ourselves first or encountered someone else already living there.

But there should be alien civilizations that are a billion years old. Anything that could conceivably be colonized, they should have gotten to back when trilobytes still seemed like superadvanced mutants. But here we are, perfectly nice solar system, lots of any type of resources you could desire, and they’ve never visited. Why not?

Well, the Great Filter. No knows specifically what the Great Filter is, but generally it’s “that thing that blocks planets from growing spacefaring civilizations”. The planet goes some of the way towards a spacefaring civilization, and then stops. The most important thing to remember about the Great Filter is that it is very good at what it does. If even one planet in a billion light-year radius had passed through the Great Filter, we would expect to see its inhabitants everywhere. Since we don’t, we know that whatever it is it’s very thorough.

Who are the drunkest NFL fans? Come on down, Buffalo Bills fans!

Filed under: Football, Health — Tags: , , — Nicholas @ 02:00

A breathalyzer company conducted a study to determine who are the drunkest fanbases in the NFL, and Buffalo turned in the highest overall score:

Apparently, losing does drive fans to drinking, at least according to a recent study done by BACtrack.

The Breathalyzer company spent the past six weeks anonymously collecting BAC samples and what they found is that Bills fans really, really, really like to drink.

According to the study, Bills fans had an average blood-alcohol level of .076 through the first seven weeks of the NFL season, which was the highest among all NFL fan bases.

If you’re wondering how BACtrack was able to hunt down the BAC level of random fans, they didn’t. The samples came to them.

The company used anonymous samples sent in by fans who were using the BACTrack app on their phone, an app that works as a Breathalyzer.

The company then collected data on Sundays between Sept. 13 and Oct. 25 to try and accurately gauge how much fans were drinking. Only samples sent in between 6 a.m. on Sunday and 5:59 a.m. on Monday counted toward the study.

The data was only collected from geographic locations that were hosting NFL games during the first seven weeks of the season.

There were probably plenty of flaws in the study, but based on what I’ve seen from Bills fans, it’s not surprising they’re No. 1.

I find it amusing that the NFC North’s drunk fan index exactly matches the teams’ relative standings right now, with Green Bay fans the most sober (at 0.042), followed by Vikings fans (0.046), then Bears fans (0.054), and finally Detroit fans (who definitely have reason to be drinking more this season) at 0.069.

The high-church organic movement is feeling under threat

Filed under: Business, Environment, Health, Media, Politics, USA — Tags: , , , , — Nicholas @ 02:00

Henry I. Miller & Julie Kelly on the less-than-certain future of the organic farming community:

The organic-products industry, which has been on a tear for the past decade, is running scared. Challenged by progress in modern genetic engineering and state-of-the-art pesticides — which are denied to organic farmers — the organic movement is ratcheting up its rhetoric and bolstering its anti-innovation agenda while trying to expand a consumer base that shows signs of hitting the wall.

Genetic-engineering-labeling referendums funded by the organic industry failed last year in Colorado and Oregon, following similar defeats in California and Washington. Even worse for the industry, a recent Supreme Court decision appears to proscribe on First Amendment grounds the kind of labeling they want. A June 2015 Supreme Court decision has cleared a judicial path to challenge the constitutionality of special labeling — “compelled commercial speech” — to identify foods that contain genetically engineered (sometimes called “genetically modified”) ingredients. The essence of the decision is the expansion of the range of regulations subject to “strict scrutiny,” the most rigorous standard of review for constitutionality, to include special labeling laws.


Organic agriculture has become a kind of Dr. Frankenstein’s monster, a far cry from what was intended: “Let me be clear about one thing, the organic label is a marketing tool,” said then secretary of agriculture Dan Glickman when organic certification was being considered. “It is not a statement about food safety. Nor is ‘organic’ a value judgment about nutrition or quality.” That quote from Secretary Glickman should have to be displayed prominently in every establishment that sells organic products.

The backstory here is that in spite of its “good vibes,” organic farming is an affront to the environment — hugely wasteful of arable land and water because of its low yields. Plant pathologist Dr. Steve Savage recently analyzed the data from USDA’s 2014 Organic Survey, which reports various measures of productivity from most of the certified-organic farms in the nation, and compared them to those at conventional farms, crop by crop, state by state. His findings are extraordinary. Of the 68 crops surveyed, there was a “yield gap” — poorer performance of organic farms — in 59. And many of those gaps, or shortfalls, were impressive: strawberries, 61 percent less than conventional; fresh tomatoes, 61 percent less; tangerines, 58 percent less; carrots, 49 percent less; cotton, 45 percent less; rice, 39 percent less; peanuts, 37 percent less.

Is it a ghost or some boring old rational explanation?

Filed under: Science — Tags: , , , , — Nicholas @ 04:00

Shaunacy Ferro is here to harsh your paranormal mellow with six possible explanations for ghostly activities:


For decades, a Canadian neuroscientist named Michael Persinger has been studying the effects of electromagnetic fields on people’s perceptions of ghosts, hypothesizing that pulsed magnetic fields, imperceptible on a conscious level, can make people feel as if there is a “presence” in the room with them by causing unusual activity patterns in the brain’s temporal lobes. […]


Infrasound is sound at levels so low humans can’t hear it (though other animals, like elephants, can). Low frequency vibrations can cause distinct physiological discomfort. Scientists studying the effects of wind turbines and traffic noise near residences have found that low-frequency noise can cause disorientation, feelings of panic, changes in heart rate and blood pressure, and other effects that could easily be associated with being visited by a ghost [PDF]. […]


Shane Rogers, an engineering professor at Clarkson University, has spent the past few months touring reportedly haunted locations looking for not-so-paranormal activity: mold growth. Preliminary research indicates that some molds can cause symptoms that sound pretty ghostly—like irrational fear and dementia. […]


In 1921, a doctor named W.H. Wilmer published an odd story about a haunted house in the medical journal the American Journal of Ophthalmology. The family who lived in this haunted residence, called the H family in the medical literature, began experiencing weird phenomena when they moved into an old house—hearing furniture moving around and strange voices in the night, feeling the presence of invisible specters. They report being held down in bed by ghosts, feeling weak, and more. As it turned out, a faulty furnace was filling their house with carbon monoxide, causing aural and visual hallucinations. The furnace was fixed, and the H family went back to their lives, sans ghosts.


In a 2014 study, Goldsmiths, University of London psychologists had participants watch a video of a “psychic” supposedly bending a metal key with his mind. In one condition, study subjects watched the video with a “participant” who was actually working with the researchers and professed to see the key bending. Those subjects were more likely to report that they saw the key bend than subjects who were paired with someone who asserted that the key didn’t bend or said nothing. […]


“There is a motivational side to belief in ghosts,” French explains. “We all want to believe in life after death. The idea of our mortality is one we are not generally comfortable with.” Confirmation bias holds powerful sway over our perceptions. “We find it much easier to believe evidence for something we want to believe anyway,” he says.

The chemistry of cider

Filed under: Science — Tags: , — Nicholas @ 02:00

At Compound Interest, a look at the making of cider:

On a hot summer’s day, the cool, refreshing taste of cider is hard to beat. But what are the chemicals behind this flavour?

Before we look at the chemistry, let’s briefly discuss how cider is made. Obviously, it starts with the apples being picked from the tree. The type of apples is, of course, a major factor in the taste of the finished cider. Bittersweet cider apples are low on acidity, but high on tannins, whilst sharp apples are the opposite. Sweet apples, meanwhile, are low in both departments, whilst bittersharp apples are high in both.

Once the apples have been picked, they’re left to mature for a time before then being scratted, or ground down, into a pulp. The pulp produced by this process is known as pomace. This pomace is then pressed to squeeze out all of the juice, which is collected into either vats or casks. At this point, it is then slowly fermented, and yeasts convert the natural sugars in the apples into alcohol. These yeasts can be the natural yeasts present in the apples, or yeasts that are added specifically for fermentation.

After fermentation is complete, the cider will often be left to mature for several months. At this point, extra sugar is sometimes added to the cider to allow fermentation to continue, and produce a small amount of carbon dioxide to carbonate the cider. However, commercially carbonation is often primarily accomplished via direct injection of carbon dioxide. In the manufacture of some ciders, they may be blended with other, older ciders, to ensure consistency of taste or to alter the flavour.

The WHO’s lack of clarity leads to sensationalist newspaper headlines (again)

Filed under: Health, Media, Science — Tags: , , , , , — Nicholas @ 05:00

The World Health Organization appears to exist primarily to give newspaper editors the excuse to run senational headlines about the risk of cancer. This is not a repeat story from earlier years. Oh, wait. Yes it is. Here’s The Atlantic‘s Ed Yong to de-sensationalize the recent scary headlines:

The International Agency of Research into Cancer (IARC), an arm of the World Health Organization, is notable for two things. First, they’re meant to carefully assess whether things cause cancer, from pesticides to sunlight, and to provide the definitive word on those possible risks.

Second, they are terrible at communicating their findings.


Group 1 is billed as “carcinogenic to humans,” which means that we can be fairly sure that the things here have the potential to cause cancer. But the stark language, with no mention of risks or odds or any remotely conditional, invites people to assume that if they specifically partake of, say, smoking or processed meat, they will definitely get cancer.

Similarly, when Group 2A is described as “probably carcinogenic to humans,” it roughly translates to “there’s some evidence that these things could cause cancer, but we can’t be sure.” Again, the word “probably” conjures up the specter of individual risk, but the classification isn’t about individuals at all.

Group 2B, “possibly carcinogenic to humans,” may be the most confusing one of all. What does “possibly” even mean? Proving a negative is incredibly difficult, which is why Group 4 — “probably not carcinogenic to humans” — contains just one substance of the hundreds that IARC has assessed.

So, in practice, 2B becomes a giant dumping ground for all the risk factors that IARC has considered, and could neither confirm nor fully discount as carcinogens. Which is to say: most things. It’s a bloated category, essentially one big epidemiological shruggie. But try telling someone unfamiliar with this that, say, power lines are “possibly carcinogenic” and see what they take away from that.

Worse still, the practice of lumping risk factors into categories without accompanying description — or, preferably, visualization — of their respective risks practically invites people to view them as like-for-like. And that inevitably led to misleading headlines like this one in the Guardian: “Processed meats rank alongside smoking as cancer causes – WHO.”

Reducing the costs of regulation

Filed under: Bureaucracy, Government, Health, USA — Tags: , , — Nicholas @ 04:00

Henry I. Miller discusses a worthwhile regulatory change that would increase the availability of medicines in the US marketplace without reducing public safety:

The FDA would be a good place to start. Bringing a new drug to market now requires 10-15 years, and costs have skyrocketed to an average of more than $2.5 billion (including both out-of-pocket and opportunity costs) – largely because FDA requirements have increased the length and number of clinical trials per marketing application, and their complexity.

The detrimental effects of FDA delays in approving certain new drugs already available in other industrialized countries are well-documented and deserve as much attention as drugs’ high costs. An example is the three-year delay in the approval of misoprostol, a drug for the treatment of gastric bleeding, which is estimated to have cost between 8,000 and 15,000 lives per year.


A practical workaround to overcome regulators’ risk-aversion and capriciousness would be “reciprocity” of approvals with certain foreign “A-list” governments, so that an approval in one country would be reciprocated automatically by the others. That would make more drugs available sooner in all of the participating countries, increasing competition and putting downward pressure on prices.

Such an innovation would also help to alleviate another critical problem: The United States is experiencing shortages of certain critical pharmaceuticals, many of which have been essential in medical practice for decades. The majority are generic injectable medications commonly used in hospitals, including analgesics, cancer drugs, anesthetics, antipsychotics for psychiatric emergencies, and electrolytes needed for patients on IV supplementation. Hospitals are scrambling to assure adequate supplies of drugs that are in short supply, or to find substitutes for them. Reciprocal approvals would make numerous alternatives available.

As referenced yesterday, the FDA regulations also create temporary monopoly situations where only one company has the permit from the regulator to produce this or that medicine, so there’s nothing standing in the way of massive price increases if there are no close substitutes to provide price competition.

Update on that $750 pill and the regulatory system that made it inevitable

Filed under: Bureaucracy, Business, Health — Tags: , , — Nicholas @ 05:00

Tim Worstall follows up on all-world scumbag Martin Shkreli and his enabled-by-the-regulator insane price increases for a decades-old drug:

We have an interesting and important economic lesson for public policy here: markets, they work. More accurately, we don’t have to worry about someone attempting to exploit their possession of a contestable monopoly. We only have to worry, possibly take action, if someone has an uncontestable monopoly. And given that there’s very few of them that we don’t create ourselves for other reasons, this means that monopoly is just one of those things we can keep a wary eye upon but not worry over excessively.

Our example comes from Martin Shkreli. The basic background is that this entrepreneur thinks he’s found a pretty cool business model. There’s a number of pharmaceuticals out there that are well out of patent but still have small and useful markets. FDA regulations (no, we’ll not go into the details of how or why this happens) mean that it’s not as easy as one might think to produce generic versions of these out of patent drugs. So, as a business plan, buy up the rights to the permit-ed (as in, with a permit, not just those allowed, as in permitted) generics and as a result of the difficulty someone else will have in getting into the same market, some pricing power is available. You can then raise the price and start to bank your considerable profits.

This caused outrage when Shkreli announced that this was exactly what he was doing:

    Turing Pharmaceuticals, the company that last month raised the price of the decades-old drug Daraprim from $13.50 a pill to $750…

A 5,000% price rise certainly indicates that Turing thinks it has pricing power and thus that it has considerable monopoly power.


Markets, they work. As Mr. Shkreli is just finding out:

    Turing Pharmaceuticals, the company that last month raised the price of the decades-old drug Daraprim from $13.50 a pill to $750, now has a competitor.

    Imprimis Pharmaceuticals, Inc., a specialty pharmaceutical company based in San Diego, announced today that it has made an alternative to Daraprim that costs about a buck a pill — or $99 for a 100-pill supply.

This is not the same drug: it’s a slight variation, a close substitute. But it’s close enough that Turing isn’t going to be making much money from what it thought was monopoly pricing power. Because it was a contestable monopoly, not an absolute one.

Consumers of porn have more feminist attitudes

Filed under: Cancon, Health, Media — Tags: , , , — Nicholas @ 02:00

We’ve all heard the claim that pornography desensitizes those who view it and dehumanizes women … except that doesn’t seem to be the case, if a recent study is accurate:

The study, published in The Journal of Sex Research, was conducted by researchers at the University of Western Ontario. “According to radical feminist theory, pornography serves to further the subordination of women by training its users, males and females alike, to view women as little more than sex objects over whom men should have complete control,” they wrote in the study abstract.

Yet after comparing people who watch porn with those who don’t, researchers found those who had watched an adult film at least once in the past year held more egalitarian ideas about women in positions of power and women working outside the home, along with more positive views toward abortion. The two groups did not differ significantly in attitudes about “traditional” families or self-identification as feminist.

“Taken together, the results of this study fail to support the view that pornography is an efficient deliverer of ‘women-hating ideology,'” study authors concluded. “While unexpected from the perspective of radical feminist theory, these results are consistent with a small number of empirical studies that have also reported positive associations between pornography use and egalitarian attitudes.”

Researchers relied on data collected between 1975 and 2010 for the General Social Survey, which asks Americans about a wide range of social issues and personal views (including gender equality and personal pornography consumption). For both men and women, viewing porn was associated with more positive attitudes toward women holding positions of power, less negative views of abortion, and less negative attitudes toward women in the workplace.

QotD: The historical triumph of public health

Filed under: Bureaucracy, Government, Health, History, Quotations — Tags: , — Nicholas @ 01:00

… the great public health achievements between roughly 1850 and 1960. Doctors and public health experts were given extraordinarily broad powers by the government, and they used them to eliminate the scourges that had made cities into pestholes from time immemorial. They built gleaming sewers and water treatment plants to wipe out virulent water-borne pathogens that used to regularly claim thousands of lives. Contact-tracing and quarantine of airborne and sexually transmitted diseases turned former plagues like smallpox and syphilis into tragic but sporadic outbreaks. Changes in building codes helped beat back mass killers like tuberculosis. Poison control cut down on both accidental and deliberate deaths. The Pure Food and Drug Act, and similar ordinances in other countries, reduced foodborne illness, and also, the casual acquisition of opiate or cocaine addictions through patent medicines. Malarial swamps were drained. Environmental toxins were identified and banned. Then they went and invented antibiotics and vaccines and vaccination laws, and suddenly surgery was as safe as a long-haul flight, TB was curable, and childhood illnesses that used to kill hundreds of people every year were a quaint footnote in your 10th-grade history textbook.

Having seen public experts work these miracles through the heavy hand of the state, people understandably concluded we could use miracles in other areas. They had a metaphor, so to speak. The metaphor wasn’t very good, as is often the case, but it took a while to find out that you couldn’t solve a problem in your steel supply chain with the same system that was so good at tracing cholera outbreaks to tainted pumps.


This is an overreaction to a terrible failure, for two reasons. First, big bureaucracies fail all the time, especially in the face of novel threats. A large institution is like a battleship: hard to sink, but also hard to turn. Public health experts of earlier eras made grave mistakes, like dumping London’s untreated sewage into the Thames; public health experts of the future will too. The more important question is whether they correct themselves, as it seems to me the CDC is now doing.

The second is that this is not your grandfather’s public health system. Public health experts were, in a way, too successful; they beat back our infectious disease load to the point where most of us have never had anything more serious than Human papillomavirus or a bad case of the flu. This left them without that much to do. So they reinvented themselves as the overseers of everything that might make us unhealthy, from French Fries to work stress.

As with the steel mills, these problems are not necessarily amenable to the organizational tools used to tackle tuberculosis. The more the public and private health system are focused on these problems, the less optimized they will be for fighting the war against infectious disease. It is less surprising to find that they didn’t know how to respond to a novel infectious disease than it would have been to discover that they botched a new campaign against texting and driving.

The entire brain weighs three pounds (1.4 kg) and so is only a small percentage of an adult’s total body weight, typically 2%. But it consumes 20% of all the energy the body uses. Why? The perhaps oversimplified answer is that time is energy.

Neural communication is very rapid — it has to be — reaching speeds of over 300 miles per hour and with neurons communicating with one another hundreds of times per second. The voltage output of a single resting neuron is 70 millivolts, about the same as the line output of an iPod. If you could hook up a neuron to a pair of earbuds, you could actually hear its rhythmic output as a series of clicks.


Neurochemicals that control communication between neurons are manufactured in the brain itself. These include some relatively well-known ones such as serotonin, dopamine, oxytocin, and epinephrine, as well as acetylcholine, GABA, glutamate, and endocannabinoids. Chemicals are released in very specific locations and they act on specific synapses to change the flow of information in the brain. Manufacturing these chemicals, and dispersing them to regulate and modulate brain activity, requires energy — neurons are living cells with a metabolism, and they get that energy from glucose. No other tissue in the body relies solely on glucose for energy except the testes. (This is why men occasionally experience a battle for resources between their brains and their glands.)
