The Economist on the cooling chances of major climate control legislation

Filed under: Environment, Government, Media, Science — Tags: , , — Nicholas @ 09:37

I was disappointed when The Economist switched sides to join the “consensus” on global warming and started arguing for massive government intervention in the economy to “save the planet”. Fifteen years after the last significant bout of warming, The Economist is starting to sound a bit more sensible (and skeptical):

…there’s no way around the fact that this reprieve for the planet is bad news for proponents of policies, such as carbon taxes and emissions treaties, meant to slow warming by moderating the release of greenhouse gases. The reality is that the already meagre prospects of these policies, in America at least, will be devastated if temperatures do fall outside the lower bound of the projections that environmentalists have used to create a panicked sense of emergency. Whether or not dramatic climate-policy interventions remain advisable, they will become harder, if not impossible, to sell to the public, which will feel, not unreasonably, that the scientific and media establishment has cried wolf.

Dramatic warming may exact a terrible price in terms of human welfare, especially in poorer countries. But cutting emissions enough to put a real dent in warming may also put a real dent in economic growth. This could also exact a terrible humanitarian price, especially in poorer countries. Given the so-far unfathomed complexity of global climate and the tenuousness of our grasp on the full set of relevant physical mechanisms, I have favoured waiting a decade or two in order to test and improve the empirical reliability of our climate models, while also allowing the economies of the less-developed parts of the world to grow unhindered, improving their position to adapt to whatever heavy weather may come their way. I have been told repeatedly that “we cannot afford to wait”. More distressingly, my brand of sceptical empiricism has been often met with a bludgeoning dogmatism about the authority of scientific consensus.

Of course, if the consensus climate models turn out to be falsified just a few years later, average temperature having remained at levels not even admitted to be have been physically possible, the authority of consensus will have been exposed as rather weak. The authority of expert consensus obviously strengthens as the quality of expertise improves, which is why it’s quite sensible, as matter of science-based policy-making, to wait for a callow science to improve before taking grand measures on the basis of it’s predictions.

As I wrote back in 2004, “I’ve never been all that convinced of the accuracy of the scientific evidence presented in favour of the Global Warming theory, especially as it seemed to play rather too clearly into the hands of the anti-growth, anti-capitalist, pro-world government folks. A world-wide ecological disaster, clearly caused by human action, would allow a lot of authoritarian changes which would radically reduce individual freedom and increase the degree of social control exercised by governments over the actions and movement of their citizenry.”

The healing powers of silver

Filed under: Health, Science — Tags: , , , — Nicholas @ 09:01

In The Economist, some new ideas about silver:

Silver has long been known as more than bling. In the fifth century BC Hippocrates noted its ability to preserve food and water. In the late 19th century silver-nitrate eye drops were administered to newborns to prevent conjunctivitis (though this remedy has since been replaced with an antibiotic). Today silver is routinely found in wound dressings and catheters to treat or prevent infections. Yet, despite its widespread use, the source of silver’s antibacterial properties has remained shrouded in mystery.

Now Jose Morones-Ramirez, from Boston University, and colleagues think they may have cracked it. As they report in Science Translational Medicine, silver fights bacteria in a number of ways.

First, silver ions (as atoms stripped of some of their electrons are known) help, through a process known as the Fenton reaction, to convert hydrogen peroxide into molecules called hydroxyl radicals. Radicals are unstable and readily react with cellular components, damaging them. Indeed, an excess is thought to contribute to ageing-related illnesses in humans. However, the researchers found, concentrations of silver ions low enough to leave human cells unscathed nonetheless appear to wreak havoc on bacterial ones.

Using a dye that glows in the presence of hydroxyl radical, Dr Morones-Ramirez treated the bacterium Escherichia coli with silver nitrate (a source of silver ions). The E. coli glowed, and then promptly bit the dust. But when the bacteria were first bathed in a chemical which mops up the hydroxyl radicals, they survived. This points to silver’s effect on the production of hydroxide radicals as the explanation.

Examining Vermouth’s claim to being the “oldest wine in the world”

Filed under: Greece, Health, History, Italy, Middle East, Wine — Tags: , — Nicholas @ 08:13

History Today linked to an article in their archives from 1975 from Pamela Vandyke Price discussing the ancient provenance of Vermouth:

When the great vermouth establishments refer to their product as ‘the oldest form of wine in the world’, they are not exaggerating. If we could travel in time, we might find many of the wines praised in antiquity to be harsh, sour and coarse to our palates, but the ‘aromatized wine’ that we know as vermouth would then have existed and, even if we drank it for medicinal or preventive reasons rather than for enjoyment, we could recognise it and relate it to the vermouths of today.

Vermouth can be, and often is, made wherever wine is made. The ancient Egyptians used both wine and beer, plus juniper, frankincense, celery, lotus leaves and honey, in the treatment of certain ailments; and it is by a method of infusion, maceration, distillation, or two or all three of these processes that, essentially, vermouth is made today. In Book IV of the Odyssey, Helen throws a drug given to her by an Egyptian lady into the bowl in which the wine is to be mixed and diluted before dinner; this ‘had the power of robbing grief and anger of their sting and banishing all painful memories’ — an efficacious aperitif, assuring good digestion. At the end of the third millennium B.C. what is perhaps the first written doctor’s prescription is recorded in cuneiform script on a tablet from the Sumerian city of Nippur — a physician notes that certain powders should be infused with a type of wine.

[. . .]

Other families in the drink business were quick to see the possibilities for vermouth, setting up in Turin, Marseilles and Sete (again in proximity to mountain herbs and a quantity of wine), and in Chambray. Many of them are still family concerns, even though they are great empires of the drink business. Martini & Rossi, who were founded about 1840, replaced a much older concern making vermouths and liqueurs at Pessione, near Turin (the head of that firm was the grandfather of Giovanni Angelli, founder of Fiat); the superb museum now established alongside the Pessione installations is a necessary detour for anyone interested in the history of wine from the earliest times.

The Cinzano family began in the drink business in the sixteenth century, and in 1757 the brothers Carlo Stefano and Giovanni Giacomo were invested as Master Distillers in Turin; today their business is gigantic, including, among other things, the Florio concern at Marsala, (itself including the former cantinas of Ingham and Woodhouse). Louis Noilly, in business at the beginning of the nineteenth century in Lyons, set up in the vermouth trade with his son-in-law, Claudius Prat and they enjoyed so much success that by 1843 they moved their headquarters to Marseilles. Madame Josephine Prat, who ran the business after the deaths of the two founders, was succeeded by her two children; and her granddaughter, Vicomtesse Vigier, who entered the firm before 1939, directed it until 1970 when she died, over a hundred years old.

It seems a little odd that, with so many modifications of wine-making and changes in the tastes of drinkers, aromatized wine should still be in demand. But, in fact, it is increasingly so. Whenever people order a straight vermouth they are ordering the oldest wine in the world.

Recognizing a sociopath

Filed under: Books, Health, Media — Tags: , , — Nicholas @ 10:06

At Marginal Revolution, Tyler Cowen discusses a book that may or may not be a dependable guide to sociopaths:

The author argues that sociopaths are often very smart, have a lot of natural cognitive advantages in manipulating data, and are frequently sought out as friends for their ability to appeal to others. It is claimed that, ceteris paribus, we will stick with the sociopath buddies, as we are quite ready to use sociopaths to suit our own ends, justly or not. It is claimed that for all of their flaws, many but not all sociopaths are capable of understanding what is in essence the contractarian case for being moral — rational self-interest — and sticking with it. Citing some research in the area (pdf), the author speculates that sociopaths may have an “attention bottleneck,” so they do not receive the cognitive emotional and moral feedback which others do, unless they decide very consciously to focus on a potential emotion. For sociopaths, top down processing of emotions is not automatic.

We even learn that (supposedly) sociopaths are often infovores. It seems many but not all sociopaths are relatively conscientious, and the author of this book (supposedly) teaches Sunday school and tithes ten percent to the church. It just so happens sociopaths sometimes think about killing or destroying other people, without feeling much in the way of remorse.

[. . .]

I cannot evaluate the scientific claims in this book, and would I trust the literature on sociopaths anyway, given that the author claims it is subject to the severe selection bias of having more access to the sociopathic losers and criminals? (I buy this argument, by the way.) It did occur to me however, that for the rehabilitation of sociopaths, whether through books or other means, perhaps they should consider…a rebranding exercise? But wait, “Sorry, I could not find synonyms for ‘sociopath’.”

If nothing else, this book will wake you up as to how little you (probably) know about sociopaths.

Ontario’s abusive relationship with sex ed

Filed under: Cancon, Education, Health, Media — Tags: , , , , , — Nicholas @ 10:31

In Maclean’s, Emma Teitel talks about the failure of Ontario’s sex-ed classes to keep up with the times:

In the fifth grade, my friends and I had a special afternoon tradition. When school let out at 3:30, we would walk to Katherine’s house (a pseudonym), raid her fridge, go upstairs to her bedroom, lock the door and watch Internet pornography. Where were Katherine’s parents? They were at work. But it wouldn’t have mattered. When they were around, we just turned off the sound, or read erotic literature on a website called Kristen Archives. This is how we gained the indispensable knowledge that some women like to be ravished by farmhands, and others, by farm animals. The year was 1999. We had not yet sat through our first sex-ed class, but when we did, almost two years later, it was spectacularly disappointing. We had seen it all, and now we were shading in a diagram of the vas deferens.

Since our special after-school tradition came to an end over a decade ago, Friendster, Myspace, Facebook, Flickr, Formspring, Instagram and Twitter have emerged. But against all logic, nothing has changed in the sex-ed business. Our century is literally on the cusp of puberty, and yet despite these enormous social and technological changes, we remain largely incapable of giving kids the resources they need to deal with their own puberty. I’m talking here, specifically, about the province of Ontario. As you read this, kids from Sarnia to Kingston — kids who, on average, have viewed Internet porn by age 11 — are probably shading in the exact same vas deferens diagram I did. There’s nothing wrong with the vas deferens — or so I’m told — but surely there is more to sexual education in the 21st century than anatomy and colouring. Ontario currently boasts the most out-of-date sex-ed curriculum in Canada. It was last revised in 1998, which means sex ed was out of date when I took it.

[. . .]

Kids shouldn’t watch porn, but they do. We can’t un-invent the Internet. And we can’t reverse puberty. Case in point: In 2001, one of the most determined voyeurs in our special after-school group skipped sex ed at the request of her religious father — for whom an hour of vas deferens shading was just too much to bear. He told her to go to the library instead, which was fine with her. Who, after all, could resist an afternoon with the Kristen Archives?

Changing the FDA to meet the new needs of personalized medicine

Filed under: Health, Science — Tags: , , , , — Nicholas @ 08:31

At Marginal Revolution, Alex Tabarrok links to a new paper by Peter Huber:

In a brilliant new paper (pdf) (html) Peter Huber draws upon molecular biology, network analysis and Bayesian statistics to make some very important recommendations about FDA policy.

[. . .]

The current regime was built during a time of pervasive ignorance when the best we could do was throw a drug and a placebo against a randomized population and then count noses. Randomized controlled trials are critical, of course, but in a world of limited resources they fail when confronted by the curse of dimensionality. Patients are heterogeneous and so are diseases. Each patient is a unique, dynamic system and at the molecular level diseases are heterogeneous even when symptoms are not. In just the last few years we have expanded breast cancer into first four and now ten different types of cancer and the subdivision is likely to continue as knowledge expands. Match heterogeneous patients against heterogeneous diseases and the result is a high dimension system that cannot be well navigated with expensive, randomized controlled trials. As a result, the FDA ends up throwing out many drugs that could do good:

    Given what we now know about the biochemical complexity and diversity of the environments in which drugs operate, the unresolved question at the end of many failed clinical trials is whether it was the drug that failed or the FDA-approved script. It’s all too easy for a bad script to make a good drug look awful. The disease, as clinically defined, is, in fact, a cluster of many distinct diseases: a coalition of nine biochemical minorities, each with a slightly different form of the disease, vetoes the drug that would help the tenth. Or a biochemical majority vetoes the drug that would help a minority. Or the good drug or cocktail fails because the disease’s biochemistry changes quickly but at different rates in different patients, and to remain effective, treatments have to be changed in tandem; but the clinical trial is set to continue for some fixed period that doesn’t align with the dynamics of the disease in enough patients

    Or side effects in a biochemical minority veto a drug or cocktail that works well for the majority. Some cocktail cures that we need may well be composed of drugs that can’t deliver any useful clinical effects until combined in complex ways. Getting that kind of medicine through today’s FDA would be, for all practical purposes, impossible.

The alternative to the FDA process is large collections of data on patient biomarkers, diseases and symptoms all evaluated on the fly by Bayesian engines that improve over time as more data is gathered. The problem is that the FDA is still locked in an old mindset when it refuses to permit any drugs that are not “safe and effective” despite the fact that these terms can only be defined for a large population by doing violence to heterogeneity. Safe and effective, moreover, makes sense only when physicians are assumed to be following simple, A to B, drug to disease, prescribing rules and not when they are targeting treatments based on deep, contextual knowledge that is continually evolving

As if a pregnant woman doesn’t have enough things to worry about…

Filed under: Health, Media — Tags: , , — Nicholas @ 00:01

…there’s an entire industry devoted to the cause of warning pregnant women about possible, potential, unknown dangers all around them:

The only other real option is to take the position held by Joan Wolf, author of the excellent study about contemporary risk thinking, Is Breast Best? Taking on the Breastfeeding Experts and the New High Stakes of Motherhood. Wolf has explored how, in the US, pregnant women are frequently told: everything is potentially risky; you have control over fetal development, but we do not know how; actions that you think are innocuous are probably harmful, but we cannot tell you which ones; things you do or do not do might be more problematic at certain times in pregnancy, but we do not know when; what you do or do not do can produce disastrous or moderately negative effects, but we cannot predict either one.

Wolf’s assessment is that the only rational response is not a call for more information of this kind; rather, it is to recognise that there is far too much of it already. While science can tell us important things, what we need to come to terms with is the inevitability of risk, the fact that people do risky things all day long (in that there are outcomes of actions over which we do not have total control), but this is just life. It is not a problem, and we do not need to be ‘informed’ or ‘empowered’ about it.

The other sort of argument made by the critics of the RCOG report was that instead of ‘raising awareness’ of the theoretical risks of everyday chemicals, more advice and information should be given to pregnant women about ‘real harm’. Hence, instead of just focusing on making it clear to the RCOG what they should do with their report, the critics have engaged in a sort of ‘my risk is bigger than your risk’ competition. In the discussion so far, the risks we apparently really understand and should be even more informed about have included all the old chestnuts: coffee, alcohol, cigarettes and stress.

Indeed, an interesting ‘my risk is bigger than your risk’ theme is developing when it comes to ‘stress’. Here, the entirely legitimate point that it is not reasonable to worry people and cause anxiety for no reason has morphed into a claim about the apparently overwhelming evidence that ‘stress’ endangers the developing fetus. In reality, as the US sociologist Betsy Armstrong has explained, the ‘science’ supporting the idea that stress in pregnancy is a problem is far more contentious than such objections assume. The wider public discourse about this issue demands robust criticism not endorsement because of its scaremongering qualities. In any case, given that a pregnant woman can no more avoid ‘stress’ in her life than a she can a pre-prepared ham sandwich, it is worth asking quite where this line of argument takes us.

When recycling makes sense – and when it doesn’t

Filed under: Economics, Environment, Government — Tags: , , , — Nicholas @ 11:14

Michael Munger examines two of the most common myths about recycling:

Almost everything that’s said about recycling is wrong. At the very least, none of the conventional wisdom is completely true. Let me start with two of the most common claims, each quite false:

  1. Everything that can be recycled should be recycled. So that should be the goal of regulation: zero waste.
  2. If recycling made economic sense, the market system would take care of it. So no regulation is necessary, and in fact state action is harmful.

If either of those two claims were true, then the debate would be over. The truth is more complicated than almost anyone admits.

There are two general kinds of arguments in favor of recycling. The first is that “this stuff is too valuable to throw away!” In almost all cases, this argument is false, and when it is correct recycling will be voluntary; very little state action is necessary. The second is that recycling is cheaper than landfilling the waste. This argument may well be correct, but it is difficult to judge because officials need keep landfill prices artificially low to discourage illegal dumping and burning. Empirically, recycling is almost always substantially more expensive than disposing in the landfill.

Since we can’t use the price system, authorities resort to moralistic claims, trying to persuade people that recycling is just something that good citizens do. But if recycling is a moral imperative, and the goal is zero waste, not optimal waste, the result can be a net waste of the very resources that recycling was implemented to conserve. In what follows, I will illustrate the problems with each of the two central fallacies of mandatory and pure-market recycling, and then will turn to the problem of moral imperatives.

Do you suffer from “social jetlag”?

Filed under: Health, Science — Tags: , — Nicholas @ 10:27

And here’s more from Brainpickings:

“Six hours’ sleep for a man, seven for a woman, and eight for a fool,” Napoleon famously prescribed. (He would have scoffed at Einstein, then, who was known to require ten hours of sleep for optimal performance.) This perceived superiority of those who can get by on less sleep isn’t just something Napoleon shared with dictators like Hitler and Stalin, it’s an enduring attitude woven into our social norms and expectations, from proverbs about early birds to the basic scheduling structure of education and the workplace. But in Internal Time: Chronotypes, Social Jet Lag, and Why You’re So Tired, a fine addition to these 7 essential books on time, German chronobiologist Till Roenneberg demonstrates through a wealth of research that our sleep patterns have little to do with laziness and other such scorned character flaws, and everything to do with biology.

In fact, each of us possesses a different chronotype — an internal timing type best defined by your midpoint of sleep, or midsleep, which you can calculate by dividing your average sleep duration by two and adding the resulting number to your average bedtime on free days, meaning days when your sleep and waking times are not dictated by the demands of your work or school schedule. For instance, if you go to bed at 11 P.M. and wake up at 7 A.M., add four hours to 11pm and you get 3 A.M. as your midsleep.

Roenneberg traces the evolutionary roots of different sleep cycles and argues that while earlier chronotypes might have had a social advantage in agrarian and industrial societies, today’s world of time-shift work and constant connectivity has invalidated such advantages but left behind the social stigma around later chronotypes.

Finland’s cardboard box babies

Filed under: Europe, Health, History — Tags: , , , — Nicholas @ 08:56

An interesting bit of history on the BBC News website:

It’s a tradition that dates back to the 1930s and it’s designed to give all children in Finland, no matter what background they’re from, an equal start in life.

The maternity package — a gift from the government — is available to all expectant mothers.

It contains bodysuits, a sleeping bag, outdoor gear, bathing products for the baby, as well as nappies, bedding and a small mattress.

With the mattress in the bottom, the box becomes a baby’s first bed. Many children, from all social backgrounds, have their first naps within the safety of the box’s four cardboard walls.

Mothers have a choice between taking the box, or a cash grant, currently set at 140 euros, but 95% opt for the box as it’s worth much more.

The tradition dates back to 1938. To begin with, the scheme was only available to families on low incomes, but that changed in 1949.

“Not only was it offered to all mothers-to-be but new legislation meant in order to get the grant, or maternity box, they had to visit a doctor or municipal pre-natal clinic before their fourth month of pregnancy,” says Heidi Liesivesi, who works at Kela — the Social Insurance Institution of Finland.

So the box provided mothers with what they needed to look after their baby, but it also helped steer pregnant women into the arms of the doctors and nurses of Finland’s nascent welfare state.

In the 1930s Finland was a poor country and infant mortality was high — 65 out of 1,000 babies died. But the figures improved rapidly in the decades that followed.

Lovers of BDSM report “a higher level of subjective well-being”

Filed under: Health, Science — Tags: , , — Nicholas @ 08:16

At Boing Boing, Xeni Jardin discusses a recent Dutch paper comparing people who indulge in BDSM with boring old “vanilla” types:

A provocative article from the Netherlands published in the Journal of Sexual Medicine says people who like to participate in bondage-discipline, dominance-submission, and sado-masochism erotic play are “characterized by a set of balanced, autonomous, and beneficial personality characteristics.”

Practitioners of BDSM report “a higher level of subjective well-being” when compared to people who tend to have more boring forms of sex.

These sexual practices have long been “associated with psychopathology,” the paper says. “However, several more recent studies suggest a relative good psychological health of BDSM practitioners.”

The article is safe for work, but you’ll quickly get into NSFW territory by doing Google searches for most of the terms used…

The war on drugs is “a holocaust in slow motion”

Filed under: Health, Law, Liberty, USA — Tags: , , , , , , — Nicholas @ 08:33

To my surprise, the creator of the TV series The Wire has come out against legalization of marijuana:

David Simon surged into the American mainstream with a bleak vision of the devastation wrought by drugs on his home town of Baltimore — The Wire, hailed by many as the greatest television drama of all time. But what keeps him there is his apocalyptic and unrelenting heresy over the failed “war on drugs”, the multibillion-dollar worldwide crusade launched by President Richard Nixon in 1971.

When Simon brought that heresy to London last week — to take part in a debate hosted by the Observer — he was inevitably asked about what reformers celebrate as recent “successes” — votes in Colorado and Washington to legalise marijuana.

“I’m against it,” Simon told his stunned audience at the Royal Institution on Thursday night. “The last thing I want to do is rationalise the easiest, the most benign end of this. The whole concept needs to be changed, the debate reframed.

“I want the thing to fall as one complete edifice. If they manage to let a few white middle-class people off the hook, that’s very dangerous. If they can find a way for white kids in middle-class suburbia to get high without them going to jail,” he continued, “and getting them to think that what they do is a million miles away from black kids taking crack, that is what politicians would do.”

If marijuana were exempted from the war on drugs, he insisted, “it’d be another 10 or 40 years of assigning people of colour to this dystopia.”

[. . .]

Simon took no prisoners. In his vision, the war on — and the curse of — drugs are inseparable from what he called, in his book, The Death of Working Class America, the de-industrialisation and ravaging of cities that were once the engine-rooms and, in Baltimore’s case, the seaboard of an industrial superpower.

The war is about the disposal of what Simon called, in his most unforgiving but cogent term, “excess Americans”: once a labour force, but no longer of use to capitalism. He went so far as to call the war on drugs “a holocaust in slow motion”.

Simon said he “begins with the assumption that drugs are bad”, but also that the war on drugs has “always proceeded along racial lines”, since the banning of opium.

It is waged “not against dangerous substances but against the poor, the excess Americans,” he said, and with striking and subversive originality, posited the crisis in stark economic terms: “We do not need 10-12% of our population; they’ve been abandoned. They don’t have barbed wire around them, but they might as well.”

Pornography isn’t the problem – you are the problem

Filed under: Health, Media, Science — Tags: , , , , , — Nicholas @ 08:43

In Psychology Today, David J. Ley explains that there’s no such thing as pornography addiction or sexual addiction:

Porn is not addictive. Sex is not addictive. The ideas of porn and sex addiction are pop psychology concepts that seem to make sense, but have no legitimate scientific basis. For decades, these concepts have flourished in America, but have consistently been rejected by medicine and mental health. The media and American society have accepted that sex and porn are addictive, because it seems intuitively true — we all feel like sometimes, we might do something stupid or self-destructive, when sex is involved. But, this false belief is dangerous, and ultimately not helpful. Because when people buy into the belief that porn is addictive, it changes the argument, and all of a sudden, it seems like it is porn and sex that are the problems. Porn addiction becomes a label, and seems to be an explanation, when in fact, it is just meaningless words and platitudes that distract from the real issue. But sex and porn aren’t the problems. You are.

People do have a strong response to video pornography. Internet porn is very good at triggering male sexuality. The economic forces of the open market have driven modern internet porn to be very, very effective at triggering male sexual buttons, to get them aroused. But women actually have a stronger physiological response to porn than men and based upon this research, women should be more addicted to pornography than men. But the overwhelming majority of the stories we hear about are men. Why is this? Because one part of this issue is an attack on aspects of male sexuality, including masturbation and use of pornography, behaviors which society fears and doesn’t understand.

Porn can affect people, but it does not take them over or override their values. If someone watches porn showing something they find distasteful, it has no impact on their behavior or desires. But, if someone watches porn depicting acts that they, the watcher, are neutral about, then it does make it slightly more likely that they express interest in trying that act themselves. Take anal sex for instance. If a porn viewer finds it disgusting, watching anal pornography isn’t going to change that. But, if they are neutral on it, then watching anal porn probably will slightly increase the chance that I would be willing to at least give it a try. But, there is the crux of the issue — the people who gravitate towards unhealthy, violent porn, are people who already have a disposition towards violence. So — the problem is not in the porn, but in those people. Regulating porn access really is going to have no impact on these people as they can (and do) find far more violent and graphic images in mainstream Hollywood films like Saw.

Here’s some often-ignored empirical science about porn — as societies have increased their access to porn, rates of sex crimes, including exhibitionism, rape and child abuse, have gone down. […] Across the world, and in America, as men have increased ability to view Internet erotica, sex crimes go down. Believe it or not — porn is good for society. This is correlational data, but it is extremely robust, repeated research. But, it is not a message that many people want to hear. Individuals may not like porn, but our society loves it, and benefits from it.
