But in the U.S., the issue is still a political non-starter for mainstream politicians, due to lingering suspicions about the fairness and practicality of a basic income, as well as a rejection of the premise that automation is actually erasing white-collar jobs.

“The sad reality is that a lot of the people who will most need a basic income are not likely to generate a lot of sympathy among volunteer donors,” Ford says. “You see this already with charitable giving—people will give for families, children, and pets—but not so much for single homeless men.” Ford cautions against what he calls the “libertarian/techno-optimistic fantasy” of a private market solution. “Government, for all its deficiencies, is going to be the only real tool in the toolbox here.”

“This is a biggie,” said Eric Kandel, the neuroscientist and Nobel Laureate. “Who thinks of the bone as being an endocrine organ? You think of the adrenal gland, you think of the pituitary, you don’t think of bone.”

he most recent finding concerns the skeleton and the brain.

The finding represents new ground in how researchers view the skeleton: not only do bones provide structural support and serve as a repository for calcium and phosphate, they issue commands to far-flung cells

As we age, our bone mass decreases. Memory loss, anxiety, and depression also become more common. These may be separate, unfortunate facts about getting old, but they could also be related.

Even more fantastically: Would it ever be possible to protect memory or treat age-related cognitive decline with a skeletal hormone? These are the kinds of questions that can spur either false hopes or imaginative leaps.

“I don’t know of any hormone that functions in mice but not to some extent in humans,” Thomas Clemens, of Johns Hopkins, told me in 2011

ne tantalizing hint comes from men who are unable to respond to the hormone as a result of a genetic mutation

Karsenty also believes that we know enough now to recognize that the body is far more networked and interconnected than most people think. “No organ is an island,” he likes to say.

working on more broadly applying [the therapy] to other forms of genetic hearing loss,” he said. But in contrast to VGLUT3 mutant mice, which are missing the protein entirely, humans with missense mutations expressed a defective transporter, making it unclear whether Lustig’s strategy could translate to human VGLUT3-linked deafness.

Taste and smell are two of the senses that have received less attention from gene therapy researchers—but that’s changing

The neurons [in VGLUT3 mutant mice] are waiting for the neurotransmitter to activate them”—but no signal comes, and the mice are profoundly deaf,

Treating the mice intra-nasally with gene therapy vectors carrying the wildtype Ift88 gene, researchers saw significant regrowth of nasal cilia, whereas control mice given empty vectors showed no regrowth. Treated mice almost doubled in weight compared to controls.

So far, no scientists have designed a gene therapy to target taste buds, but at least one team is tackling an important factor in taste: saliva. If a person’s saliva production drops below 50 percent of normal, “you get tooth decay and trouble swallowing,”

Scientists are also developing gene therapies for disorders involving touch—or at least pain-sensing—neurons, with one drug candidate

Wolfe envisions that someday pain treatment could be as simple as visiting the doctor every few months for a quick skin prick “wherever it hurts”—choosing between a variety of genes to get the best effect.

he and the other authors acknowledged the challenge in gaining traction, even with such findings, given the deep-rooted human bias toward immediate gratification and the development and energy gaps that mean today’s poorer nations have few affordable choices other than fossil fuels. See my recent look at India’s argument for expanded coal use.)

It’s real important to think about these long time scales. Essentially, what our study shows is that the changes that we bring upon within the next decades can really change the face of the Earth for thousands of years to come.

Another aspect to it that really pushes it into our century, or even our decade, is that we are emitting the carbon now and it stays in the atmosphere for a long time and the temperature remains high even longer than the carbon remains high.

But the students also described a sense of loss.

A 15-year-old boy told me that someday he wanted to raise a family, not the way his parents are raising him (with phones out during meals and in the park and during his school sports events) but the way his parents think they are raising him — with no phones at meals and plentiful family conversation. One college junior tried to capture what is wrong about life in his generation. “Our texts are fine,” he said. “It’s what texting does to our conversations when we are together that’s the problem.”

One teacher observed that the students “sit in the dining hall and look at their phones. When they share things together, what they are sharing is what is on their phones.” Is this the new conversation? If so, it is not doing the work of the old conversation. The old conversation taught empathy. These students seem to understand each other less.

In 2010, a team at the University of Michigan led by the psychologist Sara Konrath put together the findings of 72 studies that were conducted over a 30-year period. They found a 40 percent decline in empathy among college students, with most of the decline taking place after 2000.

We’ve gotten used to being connected all the time, but we have found ways around conversation — at least from conversation that is open-ended and spontaneous, in which we play with ideas and allow ourselves to be fully present and vulnerable. But it is in this type of conversation — where we learn to make eye contact, to become aware of another person’s posture and tone, to comfort one another and respectfully challenge one another — that empathy and intimacy flourish. In these conversations, we learn who we are.

the trend line is clear. It’s not only that we turn away from talking face to face to chat online. It’s that we don’t allow these conversations to happen in the first place because we keep our phones in the landscape.

It’s a powerful insight. Studies of conversation both in the laboratory and in natural settings show that when two people are talking, the mere presence of a phone on a table between them or in the periphery of their vision changes both what they talk about and the degree of connection they feel. People keep the conversation on topics where they won’t mind being interrupted. They don’t feel as invested in each other. Even a silent phone disconnects us.

we have put this virtuous circle in peril. We turn time alone into a problem that needs to be solved with technology.

At a nightly cabin chat, a group of 14-year-old boys spoke about a recent three-day wilderness hike. Not that many years ago, the most exciting aspect of that hike might have been the idea of roughing it or the beauty of unspoiled nature. These days, what made the biggest impression was being phoneless. One boy called it “time where you have nothing to do but think quietly and talk to your friends.” The campers also spoke about their new taste for life away from the online feed. Their embrace of the virtue of disconnection suggests a crucial connection: The capacity for empathic conversation goes hand in hand with the capacity for solitude.

In solitude we find ourselves; we prepare ourselves to come to conversation with something to say that is authentic, ours. If we can’t gather ourselves, we can’t recognize other people for who they are. If we are not content to be alone, we turn others into the people we need them to be. If we don’t know how to be alone, we’ll only know how to be lonely.

Yalda T. Uhls was the lead author on a 2014 study of children at a device-free outdoor camp. After five days without phones or tablets, these campers were able to read facial emotions and correctly identify the emotions of actors in videotaped scenes significantly better than a control group. What fostered these new empathic responses? They talked to one another. In conversation, things go best if you pay close attention and learn how to put yourself in someone else’s shoes. This is easier to do without your phone in hand. Conversation is the most human and humanizing thing that we do.

People sometimes say to me that they can see how one might be disturbed when people turn to their phones when they are together. But surely there is no harm when people turn to their phones when they are by themselves? If anything, it’s our new form of being together.

But this way of dividing things up misses the essential connection between solitude and conversation. In solitude we learn to concentrate and imagine, to listen to ourselves. We need these skills to be fully present in conversation.

One start toward reclaiming conversation is to reclaim solitude. Some of the most crucial conversations you will ever have will be with yourself. Slow down sufficiently to make this possible. And make a practice of doing one thing at a time. Think of unitasking as the next big thing. In every domain of life, it will increase performance and decrease stress.

Multitasking comes with its own high, but when we chase after this feeling, we pursue an illusion. Conversation is a human way to practice unitasking.

Our phones are not accessories, but psychologically potent devices that change not just what we do but who we are. A second path toward conversation involves recognizing the degree to which we are vulnerable to all that connection offers. We have to commit ourselves to designing our products and our lives to take that vulnerability into account.

We can choose not to carry our phones all the time. We can park our phones in a room and go to them every hour or two while we work on other things or talk to other people. We can carve out spaces at home or work that are device-free, sacred spaces for the paired virtues of conversation and solitude.

Families can find these spaces in the day to day — no devices at dinner, in the kitchen and in the car.

Engineers are ready with more ideas: What if our phones were not designed to keep us attached, but to do a task and then release us? What if the communications industry began to measure the success of devices not by how much time consumers spend on them but by whether it is time well spent?

The young woman who is so clear about the seven minutes that it takes to see where a conversation is going admits that she often doesn’t have the patience to wait for anything near that kind of time before going to her phone. In this she is characteristic of what the psychologists Howard Gardner and Katie Davis called the “app generation,” which grew up with phones in hand and apps at the ready. It tends toward impatience, expecting the world to respond like an app, quickly and efficiently. The app way of thinking starts with the idea that actions in the world will work like algorithms: Certain actions will lead to predictable results.

This attitude can show up in friendship as a lack of empathy. Friendships become things to manage; you have a lot of them, and you come to them with tools

here is a first step: To reclaim conversation for yourself, your friendships and society, push back against viewing the world as one giant app. It works the other way, too: Conversation is the antidote to the algorithmic way of looking at life because it teaches you about fluidity, contingency and personality.

We have time to make corrections and remember who we are — creatures of history, of deep psychology, of complex relationships, of conversations, artless, risky and face to face.

The experience of going along with temptation is not, Socrates argues, one in which the person protests or fights against its unreasonableness while being dragged along into gratifying it. For Socrates, ‘yielding to temptation’ is not being unwillingly overpowered, but is the experience of being a willing participant choosing what is at that moment wrongly thought to be best. This is also the essence of the willingness model of addictive behavior.

Aristotle thought that by asserting that when we gratify our desires for what tempts we are still doing what we think best, Socrates was denying the existence of akrasia – ‘weakness of will’, or a failure of self-restraint.

what the addict does can be explained in terms of Socrates’ willingness model and an addict’s immoral character: ie, they want to do it, and care more about satisfying their addiction than the consequences of doing so. The addict’s moral deficits reside in their motivations

These are the foods with flowers and bees and sunsets on their labels. That’s the whole point of the film. If I had been eating chocolate doughnuts and soft drinks, we know what would have happened to me. But the fact that this happened when I was following the low-fat diet that we’ve all been prescribed for 35 years – that was surprising.

The twist is that Mr. Gameau avoids soda, ice cream, candy and other obvious sources of sugar. Instead, he consumes foods commonly perceived as “healthy” that are frequently loaded with added sugars, like low-fat yogurt, fruit juice, health bars and cereal.

How did it change during the film? A. I swapped all that for the refined carbohydrates. Cereals, low-fat yogurts and apple juice would be my breakfast instead of eggs and avocado. And lunch would be pasta with pasta sauce, or some vegetables or fish with a teriyaki sauce or some kind of dressing that had added sugars in it.

My calorie intake didn’t change. What I was eating before – the avocados and nuts and other foods – are high in calories. So I kept a similar calorie intake. But on the diet with all the added sugars, I was snacking a lot more. I just never felt full, and it was affecting my moods. What I learned was that I was triggering insulin and all sorts of hormones that were trapping fat in my body.

I don’t think we should ever demonize one nutrient. But when that one single nutrient is now in 80 percent of all foods, we do need to look at it. This is not just about putting sugar in your tea or coffee. It’s pervaded our entire food supply, and people are having far too much of it. And I think most of those people don’t realize how much they’re having.

When I went back to just drinking water and eating food again, the weight dropped, and all my symptoms went away. I think we just need to simplify things. Stick to the perimeter of the supermarket where all the fresh foods are. Buy real foods as much as you can.

with the development of non-invasive brain imaging techniques, we have gathered evidence that suggests our brains are hard-wired to be unrealistically optimistic. When we learn what the future may hold, our neurons efficiently encode unexpectedly good information, but fail to incorporate information that is unexpectedly bad.

Underestimating risk makes us less likely to practice safe sex, save for retirement, buy insurance or undergo medical screenings.

Take the financial crisis of 2008. Each investor, homeowner, banker or economic regulator expected slightly better profits than were realistically warranted. On its own, each bias would not have created huge losses. Yet when combined in one market they produced a giant financial bubble that did just that.

The optimal solution then? Believe you will live a long healthy life, but go for frequent medical screenings. Aspire to write the next “Harry Potter” series, but have a safety net in place too.

Since search engines are continually available to us, we may often be in a state of not feeling we need to encode the information internally. When we need it, we will look it up."

when people expect information to remain continuously available (such as we expect with Internet access), we are more likely to remember where to find it than we are to remember the details of the item."

we've never had an "external memory" so capacious, so available and so easily searched as the web. If, as this study suggests, the way we form (or fail to form) memories is deeply influenced by the mere existence of external information stores, then we may be entering an era in history in which we will store fewer and fewer memories inside our own brains.

If a fact stored externally were the same as a memory of that fact stored in our mind, then the loss of internal memory wouldn't much matter. But external storage and biological memory are not the same thing. When we form, or "consolidate," a personal memory, we also form associations between that memory and other memories that are unique to ourselves and also indispensable to the development of deep, conceptual knowledge. The associations, moreover, continue to change with time, as we learn more and experience more. As Emerson understood, the essence of personal memory is not the discrete facts or experiences we store in our mind but "the cohesion" which ties all those facts and experiences together. What is the self but the unique pattern of that cohesion?

as memory shifts from the individual mind to the machine's shared database, what happens to that unique "cohesion" that is the self?

We are not blank slates. All humans seem to share similar sets of biases. There is such a thing as universal human nature. The trick is to understand the universals and how tightly or loosely they tie us down.

We are players in a game we don’t understand. Most of our own thinking is below awareness. Fifty years ago, people may have assumed we are captains of our own ships, but, in fact, our behavior is often aroused by context in ways we can’t see. Our biases frequently cause us to want the wrong things. Our perceptions and memories are slippery, especially about our own mental states. Our free will is bounded. We have much less control over ourselves than we thought.

They also figured out ways to navigate around our shortcomings. Kahneman champions the idea of “adversarial collaboration” — when studying something, work with people you disagree with. Tversky had a wise maxim: “Let us take what the terrain gives.” Don’t overreach. Understand what your circumstances are offer

Kahneman has given us a new set of labels for our shortcomings. But his greatest legacy, perhaps, is also his bleakest: By categorizing our cognitive flaws, documenting not just our errors but also their embarrassing predictability, he has revealed the hollowness of a very ancient aspiration. Knowing thyself is not enough. Not even close.

Studies carried out with college students have found that brief episodes are common in young people, with a prevalence ranging from 30 to 70 percent. It can happen when you’re jet-lagged, hungover, or stressed. But for roughly 1 to 2 percent of the population, it becomes persistent, and distressing

Research suggests that areas of the brain that are key to emotional and physical sensations, such as the amygdala and the insula, appear to be less responsive in chronic depersonalization sufferers. You might become less empathetic; your pain threshold might increase. These numbing effects mean that it’s commonly conceived as a defense mechanism; Hunter calls it a “psychological trip switch” which can be triggered in times of stress.

Have you ever played that game when you repeat a word over and over again until it loses all meaning? It’s called semantic satiation. Like words, can a sense of self be broken down into arbitrary, socially-constructed components?

That question may be why the phenomenon has attracted a lot of interest from philosophers. In a sense, the experience presupposes certain notions of how the self is meant to feel. We think of a self as an essential thing—a soul or an ego that everyone has and is aware of—but scientists and philosophers have been telling us for a while now that the self isn’t quite as it seems

there is no center in the brain where the self is generated. “What we experience is a powerful depiction generated by our brains for our benefit,” he writes. Brains make sense of data that would otherwise be overwhelming. “Experiences are fragmented episodes unless they are woven together in a meaningful narrative,” he writes, with the self being the story that “pulls it all together.”

“The unity [of self that] we experience, which allows us legitimately to talk of ‘I,’ is a result of the Ego Trick—the remarkable way in which a complicated bundle of mental events, made possible by the brain, creates a singular self, without there being a singular thing underlying it,”

depersonalization is both a burden, a horrible burden—but it’s in some strange way a blessing, to reach some depths, some meaning which somehow comes only in the broken mirror,” Bezzubova says. “It’s a Dostoyevsky style illumination—where clarity cannot be distinguished from pain.”

for her, the experience is pleasant. “It’s helped me in my life,” she says. Over the past few years, she has learned to interpret her experiences in a Buddhist context, and she describes depersonalization as a “deconditioning” of sorts: “The significance I place on the world is all in my mind,”

“I believe I am on the path to enlightenment,” she says.

The crossover between dark mental states and Buddhist practices is being investigated

Mindfulness has become increasingly popular in the West over the past few years, but as Britton told The Atlantic, the practice in its original form isn’t just about relaxation: It’s about the often painstaking process of coming to terms with three specific insights of the Theravadin Buddhist tradition, which are anicca, or impermanence; dukkha, or dissatisfaction; and anatta, or not-self.

depersonalization must cause the patient distress and have an impact on her daily functioning for it to be classified as clinically significant. In this sense, it seems inappropriate to call Alice’s experiences pathological. “We have ways of measuring disorders, but you have to ask if it’s meaningful. It’s an open question,”

“I think calling it a loss of self is maybe a convenient shorthand for something that’s hard to capture,” he says. “I prefer to talk about experience—because that’s what’s important in psychiatry.”

there’s also a much more direct reason for those defending the interests of the wealthy to complain about easy money: The wealthy derive an important part of their income from interest on bonds, and low-rate policies have greatly reduced this income.

Before the financial crisis, many central bankers and economists were, it’s now clear, living in a fantasy world, imagining themselves to be technocrats insulated from the political fray. After all, their job was to steer the economy between the shoals of inflation and depression, and who could object to that?

It turns out, however, that using monetary policy to fight depression, while in the interest of the vast majority of Americans, isn’t in the interest of a small, wealthy minority. And, as a result, monetary policy is as bound up in class and ideological conflict as tax policy.The truth is that in a society as unequal and polarized as ours has become, almost everything is political. Get used to it.

new research has found that taking photos -- an increasingly ubiquitous practice in our smartphone-obsessed culture -- actually hinders our ability to remember that which we're capturing on camera.

most of us aren't able to effectively manage the overload of information we're constantly bombarded with.When the working memory is experiencing digital overload, it's like a glass of water overflowing.

when we know a digital device or tool will remember a piece of information for us, we're less likely to remember it ourselves.

He explained that an over-reliance on technology has a tendency to encourage us to isolate pieces of information without fitting them into a broader cognitive schema.

A 2013 Trending Machine national poll found that millennials (aged 18-34) are more likely than those over the age of 55 to forget what day it is (15 percent vs. 7 percent) and where they put their keys (14 percent vs. 8 percent).

“We may be sitting on a precipice of a major extinction event,”

There are clear signs already that humans are harming the oceans to a remarkable degree, the scientists found. Some ocean species are certainly overharvested, but even greater damage results from large-scale habitat loss, which is likely to accelerate as technology advances the human footprint, the scientists reported.

Coral reefs, for example, have declined by 40 percent worldwide,

Fragile ecosystems like mangroves are being replaced by fish farms, which are projected to provide most of the fish we consume within 20 years.

Mining operations, too, are poised to transform the ocean. Contracts for seabed mining now cover 460,000 square miles underwater, the researchers found, up from zero in 2000.

ecosystems may seem impervious to change.

The fossil record indicates that a number of large animal species became extinct as humans arrived on continents and islands.

But it was only after 1800, with the Industrial Revolution, that extinctions on land really accelerated.

Humans began to alter the habitat that wildlife depended on, wiping out forests for timber, plowing under prairie for farmland, and laying down roads and railroads across continents.

Over the past five centuries, researchers have recorded 514 animal extinctions on land

To counter the weak employment market, Summers called for major growth in government expenditures to fill needs that the private sector is not addressing:In our society, whether it is taking care of the young or taking care of the old, or repairing a lot that needs to be repaired, there is a huge amount of very valuable work that needs to be done. It’s much less clear, to use a modern phrase, that there’s a viable business model for getting it done. And I guess the reason why I think there is going to need to be a lot of reflection on the role of government going forward is that, if I’m right, that there’s vitally important work to be done for which there is no standard capital business model that will get it done. That suggests important roles for public policy.

the report calls for tax and regulatory policies to encourage employee ownership, the strengthening of collective bargaining rights, regulations requiring corporations to provide fringe benefits to employees working for subcontractors, a substantial increase in the minimum wage, sharper overtime pay enforcement, and a huge increase in infrastructure appropriations – for roads, bridges, ports, schools – to spur job creation and tighten the labor market.

Summers also calls for significant increases in the progressivity of the United States tax system.

He advocates aggressive steps to eliminate “rents” — profits that result from monopoly or other forms of government protection from competition. Summers favors attacking rents in the form of “exclusionary zoning practices” that bid up the price of housing, “excessively long copyright” protections, and financial regulations “providing implicit subsidies to a fortunate minority.”

Signaling that he now finds himself on common ground with stalwarts of the Democratic left like Elizabeth Warren and Joe Stiglitz, Summers adds, “Government needs to try to make sure everyone can get access to financial markets on an equal basis.”

Summers supports looking past income inequality to the distribution of wealth. During our conversation, he pointed out that “a large fraction of capital gains escapes taxation entirely” through “the stepped up basis at death.”

The idea that an economy could suffer from a persistent shortage of demand is an enormous switch for Summers or anyone who had been adhering to the economic orthodoxy in the three decades prior to the crisisin 2008. Baker goes on to argue that Summers “now recognizes that the financial system needs serious regulation.”

Many of the policies outlined by Summers — especially on trade, taxation, financial regulation and worker empowerment — are the very policies that divide the Wall-Street-corporate wing from the working-to-middle-class wing of the Democratic Party. Put another way, these policies divide the money wing from the voting wing.

Summers has forced out in the open a set of choices that Hillary Clinton has so far avoided, choices that even if she attempts to elide them will amount to a signal of where her loyalties lie.

“The core problem,” according to Summers, is thatthere aren’t enough jobs, and if you help some people, you can help them get the jobs, but then someone else won’t get the jobs. And unless you’re doing things that are affecting the demand for jobs, you’re helping people win a race to get a finite number of jobs, and there are only so many of them.

he is “all for” more schooling and job training, but as an answer to the problems of the job marketplace, “it is fundamentally an evasion.”

Summers’s analysis of current economic conditions suggests that free market capitalism, as now structured, is producing major distortions. These distortions, in his view, have resulted in gains of $1 trillion annually to those at the top of the pyramid, and losses of $1 trillion every year to those in the bottom 80 percent.

Summers’s ascendance is a reflection of the abandonment by much of the party establishment of neo-liberal thinking, premised on the belief that unregulated markets and global trade would produce growth beneficial to worker and C.E.O. alike.

Larry Summers, who withdrew his candidacy for the chairmanship of the Federal Reserve under pressure from the liberal wing of the Democratic Party in 2013, has emerged as the party’s dominant economic policy strategist. The former Treasury secretary’s evolving message has won over many of his former critics.

Extensive research in many countries has demonstrated that we can build metrics around social and emotional skills that help to make them tangible for educators and policy makers

The OECD is about to publish the report "Skills for Social Progress: The Power of Social and Emotional Skills", that integrates available evidence on the importance of social and emotional skills for achieving positive life outcomes. It documents methods to measure social and emotional skills and it uses innovative analytical methods to show how social and emotional skills are drivers of social outcomes, such as health, civic engagement, and subjective well-being.

social and emotional skills are not just measurable, but also malleable. That means that schools, families and communities can play an active role in fostering these skills, they can be taught at home and school through adequate practices.

the report provides a range of examples of learning practices that worked in developing social and emotional skills. For example, teachers can enhance children's motivation, self-esteem and emotional stability by becoming effective mentors and learning facilitators.

Parents can provide warm, supportive and interactive environments through day-to-day home activities or routines

Dory, voiced by comedian Ellen DeGeneres, suffers classic symptoms of anterograde amnesia, which is typically associated with damage to the hippocampus, the area of the brain involved in encoding memories.

the portrayal of the condition is spot on. She has difficulty remembering names and retaining new information, but her condition doesn’t affect her sense of identity.

it’s just a perfect example of the neuromyth

Jason Bourne, the amnesiac main character of this action flick, exhibits no trouble with short-term memories, but wakes up after suffering an unspecified injury to the brain with no recollection of who he is.

explaining that the “double conk” myth – the idea that someone can lose their identity after being hit in the head and regain it after a second blow or psychological trigger – is actually a conflation of two ideas.

Identity loss is more closely associated with psychogenic amnesia, an extremely rare and controversial diagnosis, whose origins, some experts believe, may be influenced by culture.

This sci-fi action film relies on the conceit that humans only use 10 per cent of their brains.

Sure, filmmakers may take artistic licence, she says, but the trouble is many people actually believe we only use a portion of our brains.

she notes that due to its success, the film may have inadvertently contributed to the stereotype of the autistic savant – the notion that people with autism excel in a specific area, which, in the case of Hoffman’s character, involved dealing in numbers. In reality, Spiers says, this is very rare.

When the study drew attention and controversy, there was a moment when they both could have said: "We didn't look carefully enough at this the first time. Now we can see that it doesn't meet our standards." Instead they allowed Facebook and the PR people to take the lead in responding to the controversy.

What should this reality signal to Facebook users? Is it time to pull-back? You have (almost) no rights. You have (almost) no control. You have no idea what they're doing to you or with you. You don't even know who's getting the stuff you are posting, and you're not allowed to know. Trade secret!

Are there any particular warnings here for journalists and editors in terms of their exposure on Facebook? Yeah. Facebook has all the power. You have almost none. Just keep that in mind in all your dealings with it, as an individual with family and friends, as a journalist with a story to file, and as a news organization that is "on" Facebook.

I am not in a commercial situation where I have to maximize my traffic, so I can opt out. Right now my choice is to keep my account, but use it cynically. 

does this level of experimentation indicate the prospect of a further undermining of audience-driven news priorities and traditional news values? The right way to think about it is a loss of power—for news producers and their priorities. As I said, Facebook thinks it knows better than I do what "my" 180,000 subscribers should get from me.

Facebook has "where else are they going to go?" logic now. And they have good reason for this confidence. (It's called network effects.) But "where else are they going to go?" is a long way from trust and loyalty. It is less a durable business model than a statement of power. 

I distinguished between the "thin" legitimacy that Facebook operates under and the "thick" legitimacy that the university requires to be the institution it was always supposed to be. (Both are distinct from il-legitimacy.) News organizations should learn to make this distinction more often. Normal PR exists to muddle it. Which is why you don't hand a research crisis over to university PR people.

some commentators have questioned the practice of A/B headline testing in the aftermath of this scandal—is there a clear connection? The connection to me is that both are forms of behaviourism. Behaviourism is a view of human beings in which, as Hannah Arendt said, they are reduced to the level of a conditioned and "behaving" animal—an animal that responds to these stimuli but not those. This is why a popular shorthand for Facebook's study was that users were being treated as lab rats.

Journalism is supposed to be about informing people so they can understand the world and take action when necessary. Action and behaviour are not the same thing at all. One is a conscious choice, the other a human tendency. There's a tension, then, between commercial behaviourism, which may be deeply functional in some ways for the news industry, and informing people as citizens capable of understanding their world well enough to improve it, which is the deepest purpose of journalism. A/B testing merely highlights this tension.

ut biological complexity is only part of the challenge in figuring out what kind of theory of the brain we’re seeking.

What we are really looking for is a bridge, some way of connecting two separate scientific languages — those of neuroscience and psychology.

An example is the discovery of DNA, which allowed us to understand how genetic information could be represented and replicated in a physical structure. In one stroke, this bridge transformed biology from a mystery — in which the physical basis of life was almost entirely unknown — into a tractable if challenging set of problems

We know that there must be some lawful relation between assemblies of neurons and the elements of thought, but we are currently at a loss to describe those laws.
