“Henrich had thought he would be adding a small branch to an established tree of knowledge. It turned out he was sawing at the very trunk.”

By way of Five Feet of Fury, an interesting story about challenging some very basic assumptions about psychology:

While the setting was fairly typical for an anthropologist, Henrich’s research was not. Rather than practice traditional ethnography, he decided to run a behavioral experiment that had been developed by economists. Henrich used a “game” — along the lines of the famous prisoner’s dilemma — to see whether isolated cultures shared with the West the same basic instinct for fairness. In doing so, Henrich expected to confirm one of the foundational assumptions underlying such experiments, and indeed underpinning the entire fields of economics and psychology: that humans all share the same cognitive machinery — the same evolved rational and psychological hardwiring.

[. . .]

When he began to run the game it became immediately clear that Machiguengan behavior was dramatically different from that of the average North American. To begin with, the offers from the first player were much lower. In addition, when on the receiving end of the game, the Machiguenga rarely refused even the lowest possible amount. “It just seemed ridiculous to the Machiguenga that you would reject an offer of free money,” says Henrich. “They just didn’t understand why anyone would sacrifice money to punish someone who had the good luck of getting to play the other role in the game.”

The potential implications of the unexpected results were quickly apparent to Henrich. He knew that a vast amount of scholarly literature in the social sciences — particularly in economics and psychology — relied on the ultimatum game and similar experiments. At the heart of most of that research was the implicit assumption that the results revealed evolved psychological traits common to all humans, never mind that the test subjects were nearly always from the industrialized West. Henrich realized that if the Machiguenga results stood up, and if similar differences could be measured across other populations, this assumption of universality would have to be challenged.

Henrich had thought he would be adding a small branch to an established tree of knowledge. It turned out he was sawing at the very trunk. He began to wonder: What other certainties about “human nature” in social science research would need to be reconsidered when tested across diverse populations?

A notion that’s popped up several times in the last couple of months is that the easy access to willing test subjects (university students) introduces a strong bias to a lot of the tests, yet until recently the majority of studies disregarded the possibility that their test results were unrepresentative of the general population.

New initiative to encourage scientists to show their work (not just the mediagenic results)

Filed under: Books, Media, Science — Tags: , , , — Nicholas @ 11:26

Ed Yong on the opening of a new lab in Virginia:

The field of psychology is going through a period of introspective turmoil. One the one hand, it has never been more popular. Its results lead to attention-grabbing headlines, and fill books that sit happily on bestseller lists. Conversely, some of its own practitioners are starting to ask themselves a difficult question: What proportion of the field’s findings are genuine and reliable insights into the human mind, and what proportion are red herrings produced by questionable research practices and, in rare cases, outright fraud?

This line of questioning comes from: cases of classic results that cannot be easily reproduced; studies that have documented widespread dodgy practices that lead to false results; the publication of papers that claim the impossible, like evidence for precognition; and the outing of several fraudulent scientists (with a new case emerging literally as I write this paragraph). To some, these signs augur a looming crisis of confidence for psychology. To others, these problems are unrepresentative, and being used to damn a field that generally produces solid, reliable results.

The debates can get quite energetic, but one of the more calm-headed voices in them is Brian Nosek’s. A psychologist from the University of Virginia, Nosek has been quietly trying to turn the problems into solutions. “There hasn’t been anything new in all this recent hubbub,” he says. “We’ve been talking about these problems since the 60s, but where it stopped was people complaining. There have been a lot of people who have been frustrated at how science is operating but had no outlet for making it better.”

Nosek’s solution launches today — the Center for Open Science, a new laboratory at Charlottesville, Virginia. Unlike many new research centres, this one is less about doing great science than about making science greater. It will try to foster a new approach to research that will produce more reliable results.

Show your working

The Center’s values are epitomised in its signature project — the Open Science Framework. It’s a website that lets scientists store and share every aspect of their work, including facets that are often hidden from each other, let alone from the public. Failed experiments, the minutiae of methods, the genesis of ideas… these are often omitted from published papers or left to languish in personal file drawers. That creates strong biases in the literature, and makes it harder for people to check and reproduce each other’s work.

QotD: “There ought to be a law”

Filed under: Law, Liberty, Quotations — Tags: , , , , — Nicholas @ 00:01

Before 25-30 years ago, most people had a sense of what the law was, without having to go to law school, because they understood, intuitively, that some things were bad. Mala in se, the law calls it — “bad in itself.”

But the criminal codes have proliferated mala prohibata offenses — “bad just because the law has prohibited it” — like evil freedom-eating Tribbles for 30 years.

Do you know what you are currently permitted to do? Do you know what you will face a criminal penalty for doing?

You don’t. None of us are aware of the myriad laws we’re breaking every day, simply by doing things that seem obviously legal but some vicious Marxist bureaucrat somewhere decided to put you in jail for.

And this state of affairs works out perfectly for the Marxists.

30 years ago, you’d just assume that anything that wasn’t obviously contrary to morality was legal. That is, you’d have a built-in default setting of assuming liberty. And that assumption of liberty would then propel you to take actions.

But now, you have to assume that many things that aren’t contrary to morality are illegal anyway. And so you now have — quel coincidence! — a built-in default setting of assuming prohibition. And that assumption that many of the things you’d like to do are illegal and criminal thereby reduces your desire to take any action at all.

You become docile, unmotivated, compliant, and risk-averse.

And this state of affairs works out perfectly for those who would control you. Only half the things you’d like to do are actually criminal, but you assume the rest might be too, thus putting it in your head you need State Permission to take virtually any action besides going to work and, of course, paying the state its dues.

The odd concept that is “money”

Filed under: Economics, Government, History — Tags: , , , , , — Nicholas @ 00:03

In his nominally NFL-related column, Gregg Easterbrook talks about the phenomenon that is money:

Currency is surprisingly abstract as a concept. Money is whatever you agree to accept in trade, with the understanding that others will accept it in turn. If there’s a $20 bill in your wallet or purse, you view it as valuable because you know that others will as well. If you have $1 million in a bank account, you view it as valuable because you know that others will as well. But you can’t eat a $20 bill or sleep under a bank account. Money is valuable only if others agree that it is.

Even if money is backed by some precious substance such as gold, the abstraction doesn’t change much. You can’t eat or wear gold. You view gold as valuable only because you know that others will as well. Whether a thin sheet of linen-like paper or a gold ingot or a string of digits on an electronic financial statement, money is, itself, worthless.

That money has value only when others think it does is why currencies collapse. The ruble and the Zimbabwean dollar lost value when no one wanted them, because a person holding this currency couldn’t be sure that others would also view it as valuable. But if Barack Obama ordered the minting of a trillion-dollar platinum coin, and it was viewed as having a trillion dollars’ worth of value, then it would.

[. . .]

Bear in mind, that’s how the past six years of irresponsible debt-based federal giveaways — two years under George W. Bush, now four years under Obama — have been funded. The Federal Reserve keeps buying Treasuries, or mortgage-backed securities issued by Fannie Mae and similar federal agencies. That gives the executive branch money to spend. One division of government tells another, “Here is a new string of numbers,” and money comes into existence.

What’s underlying these transactions? Nada, beyond the belief that strings of numbers issued by the United States are more likely to be useful in trade than strings of numbers issued by, say, Greece. Because the credibility of the United States is so high, its strings of numbers bear heft. But if government keeps printing money and talking about obvious gimmicks such as trillion-dollar coins, how long will that credibility last?

Economists including Friedrich Hayek have contemplated the idea that privately issued money would be more solid than government-issued money, since privately issued money would be cross-checked by market forces, while government is run to please campaign donors. Governments from the Roman emperors of the far past to the liberal Scandinavian democracies of today insist that they alone control the supply of money. One reason is to ensure taxation. At a deeper level, governments know how easily it could all unravel, and money be viewed as worthless.

Narcissism on the rise (again) among college students

Filed under: Education, Media, Randomness, USA — Tags: , , , — Nicholas @ 09:04

I know you won’t believe this, but college students have an inflated sense of self-worth that has been further enabled by those new-fangled social media tools.

A new analysis of the American Freshman Survey, which has accumulated data for the past 47 years from 9 million young adults, reveals that college students are more likely than ever to call themselves gifted and driven to succeed, even though their test scores and time spent studying are decreasing.

Psychologist Jean Twenge, the lead author of the analysis, is also the author of a study showing that the tendency toward narcissism in students is up 30 percent in the last thirty-odd years.
This data is not unexpected. I have been writing a great deal over the past few years about the toxic psychological impact of media and technology on children, adolescents and young adults, particularly as it regards turning them into faux celebrities — the equivalent of lead actors in their own fictionalized life stories.

On Facebook, young people can fool themselves into thinking they have hundreds or thousands of “friends.” They can delete unflattering comments. They can block anyone who disagrees with them or pokes holes in their inflated self-esteem. They can choose to show the world only flattering, sexy or funny photographs of themselves (dozens of albums full, by the way), “speak” in pithy short posts and publicly connect to movie stars and professional athletes and musicians they “like.”

While the specifics of today’s worries differ, I’m reminded of this classic, attributed to Socrates (but not authenticated):

The children now love luxury; they have bad manners, contempt for authority; they show disrespect for elders and love chatter in place of exercise. Children are now tyrants, not the servants of their households. They no longer rise when elders enter the room. They contradict their parents, chatter before company, gobble up dainties at the table, cross their legs, and tyrannize their teachers.

The root problem with all self-help programs

Filed under: Books, Business, Health, Media — Tags: , , , — Nicholas @ 10:26

In New York magazine, Kathryn Schulz explains why self-help programs are so popular … and why they are so difficult for most of us:

In The Age of Anxiety, W.H. Auden observed that we human beings never become something without pretending to be it first. The corollary is more prosaic but, regrettably, at least as true: We humans never become most of the things we pretend we will someday be. Nevertheless, last Monday, you and I and several billion other incorrigible optimists raised our glasses and toasted all the ways we will be different in 2013.

It’s easy to understand why we want to be different. We are twenty pounds overweight; we are $20,000 in debt; we can’t believe we slept with that guy; we can’t believe we didn’t. What’s harder to understand is why transforming ourselves is so difficult. Changing other people is notoriously hard; the prevailing wisdom on that one is Don’t hold your breath. But it’s not obvious why changing oneself should present any difficulty at all. And yet, demonstrably, it does.

The noted self-help guru Saint Augustine identified this problem back in the fourth century A.D. In his Confessions, he records an observation: “The mind gives an order to the body and is at once obeyed, but when it gives an order to itself, it is resisted.” I cannot improve upon Augustine’s insight, but I can update his examples. Say you want to be skinny. You’ve signed on with Weight Watchers, taken up Zumba, read everything from Michael Pollan to French Women Don’t Get Fat, and scrupulously recorded your every workout, footstep, and calorie on your iPhone. So whence the impulsive Oreo binge? [. . .]

This is where the cheerfully practical and accessible domain of self-help bumps up against one of the thorniest problems in all of science and philosophy. In the 1,600 years since Augustine left behind selfhood for sainthood, we’ve made very little empirical progress toward understanding our own inner workings. We have, however, developed an $11 billion industry dedicated to telling us how to improve our lives. Put those two facts together and you get a vexing question: Can self-help work if we have no idea how a self works?

Charles Stross on vampires

Filed under: Books, Media — Tags: , , — Nicholas @ 09:41

Now that he’s committed the act of writing a novel that has vampires (The Rhesus Chart, the next “Laundry” story, to be published in July next year), Charles Stross examines the current role of vampires in fiction:

So what are vampires good for?

Leaving aside a whole bunch of different mythological tap-roots, some of which are quite interesting in their own right, the modern western interpretation of the vampire is largely the fault of Bram Stoker (although he, in turn, was working in a literary tradition with notable antecedents such as Varney the Vampire).

The interesting thing about vampires in fiction is what they’re used to represent. Vampires are the talkative reflection of our fears; unlike horde-shambling zombies they’re singular entities, intelligent and outwardly handsome, the exterior shell concealing festering horrors within. And the nature of the horrors in question changes with time. Back in Stoker’s hey-day, the fear of contagion, of the degeneration and insanity that went with syphilis, was clear: so was the clash of uptight Victorian public morality and private lascivious debauchery that went with it. (It’s no accident that Vampirism-as-AIDS was the big metaphor of the 1980s: blood, sex, and death are deeply intertwingled in our collective id.)

More recently, we have a whole bunch of other vampire metaphors. There’s the untrammeled greed angle, the psychopathic serial killer angle, the sexual predator. Vampires are rapists, non-consensual sadists and torturers, serial killers. They are, above all, parasites and sociopaths — you can’t be a vampire, a successful apex predator upon people, and feel much empathy for your prey.

So what do we make of that sub-species of vampire that fucks its food?

One of the weirder twists in the development of a sub-genre happened some time in the early 1990s, with the advent of the paranormal romance. In retrospect it’s fairly obvious what they’re for; they allow the reader to vicariously explore emotional aspects of BDSM without the troublesome need to find a partner with a roll of duct tape and a flogger who also understands the need for safe words. (This may also be a side-effect of changing gender/power relationships in society at large causing confusion, uncertainty, or dissatisfaction with traditional power roles: don’t tell the Pope. Ahem. There’s a really complex knot of issues here, including the implications of the demographic transition for human interpersonal and familial relationships, that is probably food for several PhD theses.)

“[W]hy Bleeding Heart Libertarians have their work cut out for them”

Filed under: Liberty, Media — Tags: , , , — Nicholas @ 14:02

Bryan Caplan thinks he can explain why there is a gender gap among libertarians (along with a few other gender gaps):

My study of personality psychology makes me one of the doubters. On the popular Myers-Briggs personality test, there is a huge Thinking-Feeling gap between men and women. For men, the breakdown is roughly 60% Thinking, 40% Feeling. For women, the breakdown is roughly 30% Thinking, 70% Feeling.

This Thinking/Feeling disparity explains a lot about gender gaps in college major and occupation. There’s every reason to think that this disparity can help explain gender gaps in political and social views.

To make a long story short: Thinking people tend to have “hard heads” and “hard hearts,” while Feeling people have “soft heads” and “soft hearts.” Unsurprisingly, then, Feeling people tend to hold more anti-market views. I’ve similarly found strong evidence that males “think more like economists.” This gender belief gap increases with education, consistent with a simple model where male and female students gradually learn more about whatever their personalities incline them to study.

The whole premise “Bleeding Heart Libertarianism,” of course, is that we should unbundle the hardness of our heads and the hardness of our hearts. Logically speaking, we can combine hard heads and soft hearts. Empirically, though, this combination is rare. And that’s why Bleeding Heart Libertarians have their work cut out for them. If you’re trying to sell libertarianism to Feeling people, “hard head, soft heart” ideas are more persuasive than “hard head, hard heart” ideas. But the libertarian remains at an inherent disadvantage against intellectual rivals pedaling “soft head, soft heart” ideas.

The real barrier to self-improvement is always you

Filed under: Education, Humour, Randomness — Tags: , , — Nicholas @ 10:08

Just when did we take the portal to this alternate universe where Cracked is good? For example, this article:

If you want to know why society seems to shun you, or why you seem to get no respect, it’s because society is full of people who need things. They need houses built, they need food to eat, they need entertainment, they need fulfilling sexual relationships. You arrived at the scene of that emergency, holding your pocket knife, by virtue of your birth — the moment you came into the world, you became part of a system designed purely to see to people’s needs.

Either you will go about the task of seeing to those needs by learning a unique set of skills, or the world will reject you, no matter how kind, giving and polite you are. You will be poor, you will be alone, you will be left out in the cold.

Does that seem mean, or crass, or materialistic? What about love and kindness — don’t those things matter? Of course. As long as they result in you doing things for people that they can’t get elsewhere.

[. . .]

The human mind is a miracle, and you will never see it spring more beautifully into action than when it is fighting against evidence that it needs to change. Your psyche is equipped with layer after layer of defense mechanisms designed to shoot down anything that might keep things from staying exactly where they are — ask any addict.

So even now, some of you reading this are feeling your brain bombard you with knee-jerk reasons to reject it.

The domestic terror: “I live with a son who is mentally ill. I love my son. But he terrifies me.”

Filed under: Health, USA — Tags: , , , , — Nicholas @ 12:39

Anarchist Soccer Mom has a story to tell. It’s neither pleasant nor uplifting, but it needs to be told:

I live with a son who is mentally ill. I love my son. But he terrifies me.

A few weeks ago, Michael pulled a knife and threatened to kill me and then himself after I asked him to return his overdue library books. His 7 and 9 year old siblings knew the safety plan — they ran to the car and locked the doors before I even asked them to. I managed to get the knife from Michael, then methodically collected all the sharp objects in the house into a single Tupperware container that now travels with me. Through it all, he continued to scream insults at me and threaten to kill or hurt me.

That conflict ended with three burly police officers and a paramedic wrestling my son onto a gurney for an expensive ambulance ride to the local emergency room. The mental hospital didn’t have any beds that day, and Michael calmed down nicely in the ER, so they sent us home with a prescription for Zyprexa and a follow-up visit with a local pediatric psychiatrist.

We still don’t know what’s wrong with Michael. Autism spectrum, ADHD, Oppositional Defiant or Intermittent Explosive Disorder have all been tossed around at various meetings with probation officers and social workers and counselors and teachers and school administrators. He’s been on a slew of antipsychotic and mood altering pharmaceuticals, a Russian novel of behavioral plans. Nothing seems to work.

[. . .]

When I asked my son’s social worker about my options, he said that the only thing I could do was to get Michael charged with a crime. “If he’s back in the system, they’ll create a paper trail,” he said. “That’s the only way you’re ever going to get anything done. No one will pay attention to you unless you’ve got charges.”

[. . .]

No one wants to send a 13-year old genius who loves Harry Potter and his snuggle animal collection to jail. But our society, with its stigma on mental illness and its broken healthcare system, does not provide us with other options. Then another tortured soul shoots up a fast food restaurant. A mall. A kindergarten classroom. And we wring our hands and say, “Something must be done.”

I agree that something must be done. It’s time for a meaningful, nation-wide conversation about mental health. That’s the only way our nation can ever truly heal.

God help me. God help Michael. God help us all.

Humans are not as much rational as they are rationalizing creatures

Filed under: Politics, Science — Tags: , , , — Nicholas @ 10:37

Ronald Bailey discusses a study which confirms what every con man already knew: smart people are easier to fool.

People reason chiefly to persuade others that they are right, not to find out what is true.

So claim Hugo Mercier, a postdoctoral fellow in economics and philosophy at the University of Pennsylvania, and Dan Sperber, a philosopher and cognitive scientist at the Central European University, in their provocative 2010 article, “Why Do Humans Reason? Arguments for an Argumentative Theory,” in the journal Behavioral and Brain Sciences. Now a new study by the Yale Cultural Cognition Project finds that people also use reason to convince themselves, in the face of evidence to the contrary, that they and those on their side are right.

[. . .]

In addition, both liberals and conservatives displayed ideological bias when assessing the validity of the cognitive reflection test. When climate change skeptics were characterized as open-minded, Republicans thought the test was nifty. When skeptics were branded as close-minded, more Democrats found the test results convincing. Thus, the study finds that the experimental “results were more consistent with a finding of symmetry than one of asymmetry with respect to ideologically motivated reasoning.” Ideology distorts both left-wing and right-wing thinking.

Do higher scores on the reflective cognition test temper political polarization? To get at this question, the study compared both liberals and conservatives who scored low on the reflective cognition test (the 62 percent of subjects who got no answers right) with liberals and conservatives scored higher (those who got an average of 1.6 answers right putting them in between the 80th and 90th percentile of the sample). In short, the researchers found that the higher either conservatives or liberals scored on the cognitive reflection test the more likely they were to judge the test as valid when its results supposedly confirmed their ideological views about climate change skeptics and vice versa. People skilled at systematic reasoning use that capacity to justify their beliefs rather seek out truth.

Kahan notes in passing that social psychological research has found that political independents and libertarians score better on the cognitive reflection than do liberals or conservatives (check your answers below). But before we libertarians and independents start patting ourselves on our collective backs for being the better systematic reasoners, could this simply mean that we are especially good at justifying our beliefs to ourselves?

I got the answers to all three test questions right, which means I’m even more likely to “fool myself” than the average person (according to this study, anyway).

A basic tenet of (male) human psychology seems to be misunderstood here…

Filed under: Humour, Media — Tags: , , , — Nicholas @ 12:39

Emily Esfahani Smith on “hook-up culture”:

The good news is that Sex Week is only around every two years. In 2008, the Harvard Crimson quipped: “Sex at Harvard is a year-round activity. At Yale, it lasts a week.” It’s a funny line, but not exactly true, which brings up the bad news: There is another part of the social-sexual landscape of Yale and other schools that is more lasting and endemic: the hook-up culture. In the hook-up culture, which is primarily driven by women, college students prefer to have sex with “no strings attached” — that is, they seek to have meaningless, casual sex outside of the context of a relationship. Some women consider this “empowering,” as Harden finds out by eavesdropping on a conversation between two female students, one of whom has this to say about her hook-up conquests, who are football players on campus: “If you go up to them at a party and just get them drinking, and start dancing with them, and kissing them, they will totally end up sleeping with you. They don’t even know they’re being played. They have no clue.”

Cue reality: “Could it be possible,” Harden writes, “That these girls don’t understand a fundamental fact about the human male? You normally don’t have to trick a man into having sex.” Young women today, influenced by Sex Week-style programming, have lost track of how the sexual marketplace really works.

Deception and counter-deception

Filed under: Europe, Germany, History, Military, WW2 — Tags: , , , , , — Nicholas @ 09:08

Deception in war reached a crescendo in the latter stages of World War 2, with the allies’ use of General George S. Patton’s imaginary First US Army Group (FUSAG) to pin German attention on the Pas de Calais for more than a month after the real D-Day landings in Normandy. In addition to direct propaganda and an extensive radio network generating fake messages to show the size of FUSAG, the allies also created entire dummy airfields and flotillas of fake landing craft to show up on German air recon photos. The fake planes, aircraft, and buildings were a key part of maintaining the fictitious threat of another, bigger invasion — which successfully kept a large German force away from the real landings.

Less well-known is that the Germans also indulged in this kind of deception:

In what could easily be the finest and boldest example of death-defying and cheeky nose-thumbing during the Second World War or any conflict for that matter, bomber and intruder crews of the Royal Air Force and USAAF are reputed to have bombed the Luftwaffe’s decoy airfields and dummy aircraft, not with high explosives or incendiaries, but with nothing more than dummy bombs made of wood, and painted with the smug remark “Wood for Wood”… all just to make a point.

Throughout all theatres of war, during the Second World War, from China to Holland to Kent, air forces, phsy-ops units and logistics people constructed dummy targets such as airfields, factories, truck parks, convoys and even ships, out of wood, canvas, burlap, or inflatable rubber. The decoy airfields were often populated with dummy aircraft and vehicles of such high quality, that even low flying recce aircraft with photographic equipment would have hard time telling the difference between the dummies and the real thing. The decoy airfields and dummy aircraft served several purposes simultaneously. They confused snooping enemy aircraft and hence planners as to the number of aircraft available to the opposing forces as well as to their displacement. They provided decoy targets for enemy bombers which, if attacked would prevent real aircraft from being destroyed. Often, these airfields were built near real airports in the path of attacking aircraft in the hopes that they would then drop their bombs and strafe the dummies, thereby saving the real aircraft.

Chemophobia, “a fear so rampant that it has infected an entire generation of women”

Filed under: Environment, Health, Media — Tags: , , , — Nicholas @ 12:13

Margaret Wente in the Globe and Mail:

Ms. Williams is right that our bodies contain trace amounts of pretty much everything that’s in our environment. But toxicity is a matter of degree. And technology is so advanced that we can measure trace amounts in parts per trillion. As yet, research has found no trace of harm. For example, after a comprehensive review of environmental causes and risk factors for breast cancer, the U.S. Institute of Medicine found no conclusive link between any of these chemicals and an increased risk of breast cancer. According to Scientific American, “some research shows the toxic load in breast milk to be smaller than that in the air most city dwellers breathe inside their homes.”

[. . .]

This is not to say there’s no impact from environmental factors. But these effects are small and uncertain. To eliminate them all, we’d have to eliminate modernity and return to being hunter-gatherers again.

But I’m afraid chemophobia is here to stay. Fear sells. Fear of chemicals manufactured by rapacious, greedy, money-sucking capitalist enterprises sells even better. Fear is is the main product peddled by interest groups such as the Environmental Defence Fund, which has been quite successful at marketing the notion that invisible dangers lurk all around us. The media love this stuff because it makes for easy headlines: If your shampoo doesn’t kill you, your lipstick will! Fear is a staple of celebrity experts like Dr. Oz, who has advised readers to avoid toxic sales receipts from fast-food restaurants and gas stations.
