Stereotypes, “gaydar”, and sexual orientation

Filed under: Randomness, Science — Tags: , , — Nicholas @ 08:38

In (of all places) the Toronto Star, Brian Platt says that “gaydar” is a real thing and that it works better for conservatives than for liberals:

In less than the blink of an eye, your subconscious “gaydar” makes a judgment about someone’s sexual orientation based entirely on facial traits — and it’s usually right.

So says the research of Nicholas Rule, a University of Toronto psychologist giving a talk on the subject this week as part of WorldPride. “The gist of it is that people can accurately judge someone’s sexual orientation from very minimal information about them,” Rule said in an interview.

“You only need to see a face for less than 40 milliseconds to judge sexual orientation with the same level of accuracy that you get if you take all the time in the world.

“To put that in perspective, it takes 400 milliseconds to blink your eye.”

Facial “gaydar” is 65-per-cent accurate on average, according to Rule and his co-researchers at U of T’s Social Perception & Cognition Laboratory. These judgments can be reliably made based on the eyes alone, though facial shape and texture are also big factors.

“Conservatives are more accurate than liberals in making these judgments when they study a face, because conservatives are more likely to use stereotypes,” Rule said. “Of course, stereotypes are often wrong, but they do have what we call kernels of truth. Liberals tend to not want to use stereotypes in making judgments, and it impairs their accuracy.”

QotD: Modern Autism

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

There are, I believe, a few reasons to suppose that autism is a particularly fascinating area to be studying at the moment. What are those reasons? Firstly, prevalence rates of autism have soared in recent decades, from 1:2,500 in 1978 to around 1:100 today: a staggering 25-fold increase. Secondly, and simultaneously, the nature of those receiving a diagnosis of autism has changed considerably. To give just one example, in the 1980s no more than twenty percent of individuals diagnosed with autism had an I.Q. above 80. Today, by contrast, it is widely argued that “intellectual disability is not part of the broader autism phenotype… [and] the association between extreme autistic traits and intellectual disability is only modest” (Hoekstra et al. 2009: 534). Whatever you make of I.Q. scores, this changing profile means that it is reasonable to assume that when you meet somebody with autism today they are quite unlikely to be similar to someone you would’ve met with the same diagnosis just thirty years ago. Thirdly, as the number of people diagnosed with autism has increased, and as the capabilities of those individuals has increased, a (self-)advocacy network of enormous importance and influence has arisen, perhaps on a scale hitherto unseen. When woven together, these dynamic elements have led Ian Hacking to claim that, in autism, “we are participating in a living experiment in concept formation of a sort that does not come more than once in a dozen lifetimes” (Hacking 2009: 506). This, I think, is quite exciting.

QotD: Environmentalism and capitalism

Filed under: Economics, Environment, Quotations — Tags: , — Nicholas @ 00:01

Environmentalists seem to all feel that capitalism is the enemy of sustainability, but in fact capitalism is the greatest system to promote sustainability that has ever been devised. Every single resource has a price that reflects its relative scarcity as compared to demand. Scarcer resources have higher prices that automatically promote conservation and seeking of substitutes. So an analysis of an investment’s ability to return its cost is in effect a sustainability analysis. What environmentalists don’t like is that wind does not cover the cost of its resources, in other words it does not produce enough power to justify the scarce resources it uses. Screwing around with that to only look at some of the resources is just dishonest.

[…]

I did not critique the analysis of energy payback per se, but if I were to dig into it, I would want to look at two common fallacies with many wind analyses. 1) They typically miss the cost of standby power needed to cover wind’s unpredictability, which has a substantial energy cost. In Germany, during their big wind push, they had to have 80-90% of wind power backed up with hot fossil fuel backup. 2) They typically look at nameplate capacity and not real capacities in the field. In fact, real capacities should further be discounted for when wind power produces electricity that the grid cannot take (ie when there is negative pricing in the wholesale market, which actually occurs).

The science of booze

Filed under: History, Science, Technology, Wine — Tags: , , — Nicholas @ 09:18

Mankind has been making alcoholic beverages for thousands of years, yet there are still some pretty basic things we don’t know about alcohol:

Consider the number of things we still don’t know: Yeast, the single-celled fungus responsible for fermentation (the conversion of sugar into alcohol), seems to have been domesticated about 12,000 years ago, but we don’t know for sure where it came from, why it makes ethanol, or why some strains do it better than others.

The physics of distillation are well established, but nobody knows who invented it — an alchemist in ancient Alexandria called Maria the Jewess? — and getting a consistent taste from the finicky process is more an art than a science.

Aging in toasted barrels clearly does hooch good, as the wood breaks down and the liquid penetrates its pores to mix with tannins and other molecules. But the final flavor of a spirit depends on everything from the temperature in the warehouse where it is aged to the climate where the trees are grown, and attempts to create synthetic processes to season liquor quicker (read: more profitably) have come mostly to naught.

Even at the most basic level, scientists don’t yet understand why booze makes us feel the way it does. Alcohol’s mode of action in the brain is much more complicated and elusive than that of a drug such as heroin, which locks into specific, identified receptors meant for natural neurotransmitters. “The truth is, we don’t know at the molecular level what alcohol is binding to,” Rogers quotes the director of the National Institute on Alcohol Abuse and Alcoholism as saying. “It’s never been resolved.”

QotD: Obesity and the federalization of food

Filed under: Bureaucracy, Food, Government, Health, Quotations — Tags: , — Nicholas @ 06:35

One of the problems with scrupulously “sanitized” food is that it doesn’t taste of anything very much, which may be why people consume it in large quantities: With food, if the taste doesn’t satisfy you, you chow until the sheer quantity does. I’ve no research on the subject and my theory may be as full of holes as a Swiss cheese, but the fact is that the federalization of food has coincided with the massive expansion of obesity in America, and I’m inclined to think these two things are not unrelated.

Falsifiability as a way to test your beliefs

Filed under: Science — Tags: — Nicholas @ 10:44

Wendy McElroy asks whether you really want to be correct:

Some circumstantial evidence is very strong, as when you find a trout in the milk.” – Henry David Thoreau

Evidence that something is wrong with a theory is rarely as obvious as a trout in the milk. This is particularly true when a belief is deeply-held or invested with emotion.

One of the most powerful intellectual tools to test your own beliefs is a modified form of “falsification” (or refutation), a concept popularized by the philosopher Karl Popper. He argued that the process of trying to prove a scientific hypothesis through amassing evidence in support was the reverse of what should occur. A scientist should attempt to disprove his hypothesis by finding contradictory evidence.

His reason was simple but compelling. Popper agreed with Albert Einstein who once stated, “No amount of experimentation can ever prove me right; a single experiment can prove me wrong.” Popper used the now-classic example of the general statement, “all swans are white.” No matter how many white swans are counted, the statement cannot be proven. But one black swan disproves it.

Falsification was not intended to assess general beliefs or ideologies but the process can be loosely bent to that purpose. In fact, Popper himself used falsifiability in rejecting Marxism and Freudianism. Adapting falsifiability to become a general intellectual tool means that a person should reverse the normal process of trying incessantly to prove his beliefs are correct by amassing confirming evidence. Instead, he should pause every once in a while and ask, “What, in principle, would disprove my belief in X or Y?” For many people, this process offers an entirely fresh perspective on their own ideas.

[…]

Falsification has limitations and it is generally unpopular with contemporary philosophers who point to such flaws as the theory itself being unfalsifiable. Moreover, not all beliefs need to be based on evidence. Many personal beliefs are just that – personal; many religious beliefs fall into this category. But if you want to argue that a position is objectively true, then falsifiability is a quick and effective technique by which to test your beliefs, to get insight into how firmly you hold them … and why.

QotD: Regulating cheese

Filed under: Bureaucracy, Food, France, Health, Quotations, USA — Tags: , , — Nicholas @ 07:00

France, for all its faults, has genuinely federalized food: a distinctive cheese every 20 miles down the road. In America, meanwhile, the food nannies are lobbying to pass something called the National Uniformity for Food Act. There’s way too much of that already.

The federalization of food may seem peripheral to national security issues, and the taste of American milk — compared with its French or English or even Québécois equivalents — may seem a small loss. But take almost any area of American life: what’s the more common approach nowadays? The excessive government regulation exemplified by American cheese or the spirit of self-reliance embodied in the Second Amendment? On a whole raft of issues from health care to education the United States is trending in an alarmingly fromage-like direction.

Regulating cosmetics

Filed under: Business, Government, Health — Tags: , , — Nicholas @ 11:43

Jeffrey Tucker discusses the coming crash in the world of make-up:

The organization Campaign for Safe Cosmetics doesn’t just want you to be able to have new choices about the makeup or other products you buy. It wants the FDA to be able to ban and recall products. It will decide for you what is and isn’t safe.

And it is prevailing against the industry itself, which has no interest whatsoever in selling unsafe products, but precisely the opposite. The industry is already ridiculously overregulated.

What’s the excuse? The usual nonsense about safety and security and health, along with predictable headlines about how your shampoo is giving you cancer. There is a crowd of lobbyists backed by regulators who seem to believe that all of modernity is corrupting and horrible and must be reversed until we are living in the most-primitive state of being, sans makeup, of course.

In other words, cosmetics are going the way of everything else. The quality of the product will be depleted by regulations, just as with indoor plumbing, electricity, cars, light bulbs, soaps and gas-powered tools. Entrepreneurship will be hindered and truncated. Innovation will stop. In a few years, you will wonder: Whatever happened to makeup and deodorant and hair spray that actually works? Prepare: The end is near!

Already, I’ve heard many women complain that cosmetics today are far worse than they were 10 years ago. The colors don’t behave they way they should, and color is mainly what the FDA currently controls. I don’t doubt that whatever problems exist are due to government regulations. Whenever you see consumer products that decline in quality to the point that you have to pay vastly more for something of good quality, or that high quality suddenly becomes completely unavailable, you will find the hand of government if you look hard enough.

Six “red flags” to identify medical quackery

Filed under: Health, Media — Tags: , , — Nicholas @ 10:01

Dr. Amy Tuteur shares six things to watch for in health or medical reporting, as they usually indicate quackery:

Americans tend to be pretty savvy about advertising. Put a box around claims, annotate them with the words “paid advertisement” or “sponsored content” and most people approach those claims warily. Unfortunately, the same people who are dubious about advertising claims are remarkably gullible when it comes to quackery.

That’s the bad news. The good news is that it is surprisingly easy to tell quackery apart from real medical information. Quack claims are typically decorated with red flags … if you know what to look for. What follows is a list of some of those red flags.

1. The secret knowledge flag: When someone implies they are sharing secret medical knowledge with you, run in the opposite direction. There is no such thing as secret medical knowledge. In an age where there are literally thousands of competing medical journals, tremendous pressure on researchers to publish papers, and instantaneous dissemination of results on the Internet, nothing about medicine could possibly be secret.

2. The giant conspiracy flag: In the entire history of modern medicine, there has NEVER been a conspiracy to hide lifesaving information among professionals. Sure, an individual company may hide information in order to get a jump on competitors, or to deny harmful effects of their products, but there can never be a large conspiracy because every aspect of the healthcare industry is filled with competitors. Vast conspiracies, encompassing doctors, scientists and public health officials exist only in the minds of quacks.

[…]

4. The toxin flag: I’ve written before that toxins are the new evil humors. Toxins serve the same explanatory purpose as evil humours did in the Middle Ages. They are invisible, but all around us. They constantly threaten people, often people who unaware of their very existence. They are no longer viewed as evil in themselves, but it is axiomatic that they have be released into our environment by “evil” corporations. There’s just one problem. “Toxins” are a figment of the imagination, in the exact same way that evil humours and miasmas were figments of the imagination.

Healthy eating … the Woody Allen moment approaches

Filed under: Food, Government, Health, Media, USA — Tags: , , , — Nicholas @ 10:22

The “prophecy”:

And in The Economist this week:

Ms Teicholz describes the early academics who demonised fat and those who have kept up the crusade. Top among them was Ancel Keys, a professor at the University of Minnesota, whose work landed him on the cover of Time magazine in 1961. He provided an answer to why middle-aged men were dropping dead from heart attacks, as well as a solution: eat less fat. Work by Keys and others propelled the American government’s first set of dietary guidelines, in 1980. Cut back on red meat, whole milk and other sources of saturated fat. The few sceptics of this theory were, for decades, marginalised.

But the vilification of fat, argues Ms Teicholz, does not stand up to closer examination. She pokes holes in famous pieces of research — the Framingham heart study, the Seven Countries study, the Los Angeles Veterans Trial, to name a few — describing methodological problems or overlooked results, until the foundations of this nutritional advice look increasingly shaky.

The opinions of academics and governments, as presented, led to real change. Food companies were happy to replace animal fats with less expensive vegetable oils. They have now begun abolishing trans fats from their food products and replacing them with polyunsaturated vegetable oils that, when heated, may be as harmful. Advice for keeping to a low-fat diet also played directly into food companies’ sweet spot of biscuits, cereals and confectionery; when people eat less fat, they are hungry for something else. Indeed, as recently as 1995 the AHA itself recommended snacks of “low-fat cookies, low-fat crackers…hard candy, gum drops, sugar, syrup, honey” and other carbohydrate-laden foods. Americans consumed nearly 25% more carbohydrates in 2000 than they had in 1971.

It would be ironic indeed if the modern obesity crisis was actually caused by government dietary recommendations intended to improve public health (and fatten the bottom lines of big agribusiness campaign donors).

“The smoke from this plant causes a brief state of euphoria, immediately followed by permanent insanity”

Filed under: Government, Health, Media — Tags: , , , , — Nicholas @ 10:29

Paula Bolyard says that this collection of TV public service announcements from the 1970s may go a long way to explain why as parents they obsessively over-protect their kids (the Millenial generation). I loved this one:

In an effort to communicate a hip-sounding anti-drug message that teens could relate to, this PSA probably achieved the opposite of its intended effect. It made drugs seem fun and cool and glamorized drug use more than demonizing it.

Here are some gems from this hilarious PSA:

    I know what you’re thinking. What is marijuana? What makes it so dangerous? Where can I get some marijuana? Well, brother, I’m not going to nickle and dime you. I’m not like ‘the man’ all you kids are rebelling against. I’m hip. I know what young people are dealing with these days.

Yes, he actually said “nickle and dime you.”

    Rolled in Zig Zags or puffed from 7th period wood shop projects, the smoke from this plant causes a brief state of euphoria, immediately followed by permanent insanity. Users are prone to unpredictable behavior including junk food binges, joy rides, and a sudden urge to wear sunglasses at night.

At long last I now know why my brother was so interested in wood shop in junior high.

    Long term use of marijuana can lead to a psychological dependency. Soon you’ll be taking all sorts of measures to get your fix. People will start calling you names like ‘pothead’ or ‘Smokie McBongwater.’ Losing all motivation, it’s likely that you will drop out of school take a sudden liking to sitar music and maybe even get felt up by a cop or two.

This explains basically everything about the 70s.

    Is marijuana really where it’s at? Is it really as righteous as you think? There is more to life than grass. There are fulfilling careers and grrrr000vy beach parties. The closer you look the more seeds you find in your stash. Follow your hopes and dreams. Be someone. Do yourself and your country a favor. Don’t let this happen to you.

Raise your hand if you’re convinced.

The argument against raising minimum prices for alcohol

Filed under: Economics, Government, Health — Tags: , , — Nicholas @ 08:37

Earlier this year, A Very British Dude explained why “evidence-based” policy making isn’t actually what it says on the label, and illustrates it with the example of minimum pricing for alcohol:

Who could possibly be against “evidence-based” policy?

The problem is very simple. It’s almost impossible to conduct experiments in the social sciences. No government can alter one economic variable and measure the outcome. The noise to signal ratio is absurdly high. What you’re left with is explanations of the data that may or may not stumble on the actual causality.

Some things are obviously and self-evidently stupid. Socialism for example — high marginal tax-rates, nationalisation, closing down markets where possible in favour of state monopolies failed. And in as perfect an economic experiment as any undertaken, two nations, both shattered by war and populated by Germans went head to head. The Capitalist system turned out to be much, much less shit than socialism. Yet many social “scientists” still seem intent on manufacturing evidence that the solutions once tried in East Germany are not only feasible, but that any other approach is both doomed to failure and wicked.

Instead of evidence-based policy, what you often get is policy-based “evidence”. You have the same political arguments, dressed up in a kind of pseudo scientific hocus-pocus.

Take the “debate” about minimum pricing as a classic example.

First make a heroic assumption. Assume a fall in alcohol consumption per head is desirable (it isn’t, what we want to do is reduce “problem” drinking). Second, ignore the fact that your desired outcome is happening anyway. Third, ignore all the evidence that “problem” drug-takers have a lower elasticity of demand and assume that minimum pricing will mostly affect the consumption by alcoholics. Fourth, express these assumptions in a spreadsheet, with no real-world evidence. Fifth, describe this spreadsheet as a “model“. The zeroth step is, of course to get a university to describe you as “professor” first. Then you’re able to tout your guesswork and call it “evidence”, to politicians, and unmolested by any critical thought on the Today program and be paid handsomely from tax-payers’ funds to make this “evidence” up into the bargain.

So you have an “evidence-based” policy to impose a minimum unit price on Alcohol. It’s regressive, and probably won’t work. It will reduce moderate drinking by sensible people, making them at the margin, unhappier. It is unlikely to reduce problem drinking, but may make problem drinkers substitute clothes, or food, or heating for their more expensive booze. Nice one. Everyone’s poorer.

Russian rocket export ban means increasing opportunities for private enterprise in space

Filed under: Russia, Space, Technology, USA — Tags: , , , , — Nicholas @ 09:46

Strategy Page looks at the knock-on effects of the Russian government banning the export of rocket engines to the United States:

The U.S. government is being forced to use satellite launchers developed without government financing because the usual methods of obtaining these launchers is falling apart and currently is unable to supply enough rockets to get all American military satellites into orbit. The immediate cause of this problem is the recent (since earlier this year) Russian aggression against Ukraine. The U.S. responded to this aggression by placing sanctions on some Russian officials and firms. Russia responded to that by halting RD-180 shipments to the United States. That’s breach of contract and it will do enormous damage to Russian exports in the future because now many countries and firms realize that a contract with a Russian firm can be cancelled by the Russian government for any reason. This was always seen as a risk when doing business with Russia and many Western firms declined to do so or have pulled out of Russia in the last decade because of the growing unreliability of Russia as a business partner. The RD-180 affair got a lot of publicity, all of it bad with regard to future Russian exports of high-end industrial items. Europe, which gets about a third of its natural gas from Russia, is already looking for alternate sources and investors are fleeing Russia (and taking their money with them).

[…]

This is good news for the new private firms that are developing rockets for launching stuff into orbit. One such firm is SpaceX (Space Exploration Technologies Corporation) and is has been trying to break the current cartel controlling U.S. government satellite launch services. Since 2006 all this business has gone to a government-approved monopoly called the ULA (United Launch Alliance) which is composed of Lockheed Martin (Atlas 5 rocket) and Boeing (Delta 4). These two firms have dominated U.S. space launches for over half a century. Because of the RD-180 the Atlas 5 is more attractive (in terms of performance and price) than the Delta 4. Meanwhile SpaceX expects to have Atlas 5 competitor ready in a few years.

In 2012 SpaceX obtained its first contract to launch U.S. military cargo into space. SpaceX had earlier obtained a NASA contract which included 12 deliveries to the International Space Station (at $134 million each). What makes all this so noteworthy is that SpaceX developed its own launch rockets without any government help. SpaceX also developed the Dragon space vehicle, for delivering personnel and supplies to the International Space Station.

SpaceX has since proved that its rockets work and is pointing out that the SpaceX rockets can do the job cheaper that ULA. Currently ULA gets a billion dollar a year subsidy from the government that SpaceX would not require. SpaceX still has to get all the paperwork and approvals done so that they can handle classified missions. SpaceX does not see this as a problem, it’s simply going to take another year to satisfy all the bureaucrats and regulations.

He was for the Veterans Health Administration before he was against it

The Wall Street Journal‘s James Taranto rounds up some amusing-in-hindsight bloviations by Paul Krugman about the efficiencies of the Veterans Health Administration:

There was no ObamaCare in January 2006, when former Enron adviser Paul Krugman wrote this:

    I know about a health care system that has been highly successful in containing costs, yet provides excellent care. And the story of this system’s success provides a helpful corrective to anti-government ideology. For the government doesn’t just pay the bills in this system — it runs the hospitals and clinics.

    No, I’m not talking about some faraway country. The system in question is our very own Veterans Health Administration, whose success story is one of the best-kept secrets in the American policy debate.

The “secret” of the VA’s “success,” Krugman argued, “is the fact that it’s a universal, integrated system.” That saves on administrative costs and allows for efficient record-keeping. Krugman acknowledged that the VA had a history of mismanagement and mediocre care, until “reforms beginning in the mid-1990’s transformed the system.” But wait. Hasn’t it been a universal, integrated system all along? Maybe the secret is something else. At any rate, the Phoenix revelations suggest it’s the system’s failures that are being kept secret.

Krugman lamented that his argument “runs completely counter to the pro-privatization, anti-government conventional wisdom that dominates today’s Washington.” That was 2006, remember, when Republicans had the White House and both houses of Congress. If Krugman is to be believed — a big “if,” to be sure — the Bush administration did a far better job running the VA than the Obama administration is doing now. Which reminds us of something Waldman wrote: “There’s an old saying that when they’re out of office, Republicans argue that government is inefficient and incompetent, and when they get in office, they set about to prove it.”

Krugman concluded that 2006 column as follows:

    Ideology can’t hold out against reality forever. Cries of “socialized medicine” didn’t, in the end, succeed in blocking the creation of Medicare. And farsighted thinkers are already suggesting that the Veterans Health Administration, not President Bush’s unrealistic vision of a system in which people go “comparative shopping” for medical care the way they do when buying tile (his example, not mine), represents the true future of American health care.

Good Glitches,” anyone?

Krugman managed to get two more columns out of the glorious VA. One, in September 2006, also damned Medicare Advantage and complained that the administration opposed the idea of letting elderly vets use Medicare benefits at VA hospitals:

    “Conservatives,” writes Time, “fear such an arrangement would be a Trojan horse, setting up an even larger national health-care program and taking more business from the private sector.”

    Think about that: they won’t let vets on Medicare buy into the V.A. system, not because they believe this policy initiative would fail, but because they’re afraid it would succeed.

OK, but think about this: According to The-Military-Guide.com, “if you’re eligible for any level of VA care, whether it’s high-priority or low-priority, you’re no longer eligible for ACA exchange subsidies.” (ACA is an abbreviation for PPACA, in turn an abbreviation for the Patient Protection and Affordable Care Act, ObamaCare’s official title.) There are worse things than being excluded from ObamaCare, of course — but the VA may be one of them.

QotD: Futurologists

Futurologists are almost always wrong. Indeed, Clive James invented a word – “Hermie” – to denote an inaccurate prediction by a futurologist. This was an ironic tribute to the cold war strategist and, in later life, pop futurologist Herman Kahn. It was slightly unfair, because Kahn made so many fairly obvious predictions – mobile phones and the like – that it was inevitable quite a few would be right.

Even poppier was Alvin Toffler, with his 1970 book Future Shock, which suggested that the pace of technological change would cause psychological breakdown and social paralysis, not an obvious feature of the Facebook generation. Most inaccurate of all was Paul R Ehrlich who, in The Population Bomb, predicted that hundreds of millions would die of starvation in the 1970s. Hunger, in fact, has since declined quite rapidly.

Perhaps the most significant inaccuracy concerned artificial intelligence (AI). In 1956 the polymath Herbert Simon predicted that “machines will be capable, within 20 years, of doing any work a man can do” and in 1967 the cognitive scientist Marvin Minsky announced that “within a generation … the problem of creating ‘artificial intelligence’ will substantially be solved”. Yet, in spite of all the hype and the dizzying increases in the power and speed of computers, we are nowhere near creating a thinking machine.

Bryan Appleyard, “Why futurologists are always wrong – and why we should be sceptical of techno-utopians: From predicting AI within 20 years to mass-starvation in the 1970s, those who foretell the future often come close to doomsday preachers”, New Statesman, 2014-04-10.
