quantum computing relies on the fact that subatomic particles inhabit a range of states. Different relationships among the particles may coexist, as well. Those probable states can be narrowed to determine an optimal outcome among a near-infinitude of possibilities, which allows certain types of problems to be solved rapidly.

“This is a revolution not unlike the early days of computing,” he said. “It is a transformation in the way computers are thought about.”

It could be possible, for example, to tell instantly how the millions of lines of software running a network of satellites would react to a solar burst or a pulse from a nuclear explosion — something that can now take weeks, if ever, to determine.

Mr. Brownell, who joined D-Wave in 2009, was until 2000 the chief technical officer at Goldman Sachs. “In those days, we had 50,000 servers just doing simulations” to figure out trading strategies, he said. “I’m sure there is a lot more than that now, but we’ll be able to do that with one machine, for far less money.”

If Microsoft’s work pans out, he said, the millions of possible combinations of the proteins in a human gene could be worked out “fairly easily.”

Quantum computing has been a goal of researchers for more than three decades, but it has proved remarkably difficult to achieve. The idea has been to exploit a property of matter in a quantum state known as superposition, which makes it possible for the basic elements of a quantum computer, known as qubits, to hold a vast array of values simultaneously.

There are a variety of ways scientists create the conditions needed to achieve superposition as well as a second quantum state known as entanglement, which are both necessary for quantum computing. Researchers have suspended ions in magnetic fields, trapped photons or manipulated phosphorus atoms in silicon.

In the D-Wave system, a quantum computing processor, made from a lattice of tiny superconducting wires, is chilled close to absolute zero. It is then programmed by loading a set of mathematical equations into the lattice. The processor then moves through a near-infinity of possibilities to determine the lowest energy required to form those relationships. That state, seen as the optimal outcome, is the answer.

The teams with training that engaged in probabilistic thinking performed best. The training involved learning some of the lessons included in Daniel Kahneman’s great work, “Thinking, Fast and Slow.” For example, they were taught to alternate between taking the inside view and the outside view.

Most important, participants were taught to turn hunches into probabilities. Then they had online discussions with members of their team adjusting the probabilities, as often as every day

In these discussions, hedgehogs disappeared and foxes prospered. That is, having grand theories about, say, the nature of modern China was not useful. Being able to look at a narrow question from many vantage points and quickly readjust the probabilities was tremendously useful.

In the second year of the tournament, Tetlock and collaborators skimmed off the top 2 percent of forecasters across experimental conditions, identifying 60 top performers and randomly assigning them into five teams of 12 each. These “super forecasters” also delivered a far-above-average performance in Year 2. Apparently, forecasting skill cannot only be taught, it can be replicated.

He believes that this kind of process may help depolarize politics. If you take Republicans and Democrats and ask them to make a series of narrow predictions, they’ll have to put aside their grand notions and think clearly about the imminently falsifiable.

Of the 3,060 students who applied to his school this year, 44 percent were boys. To help rank the candidates, he said, he simply adjusted the focus of student interviews to more effectively draw boys out in describing their own strengths. This year he offered seats to 136 boys and 134 girls. “Are we worried about getting unqualified boys?” asked Dr. Lerner. “No not at all.”

Consequently, he said, “it inflates the language. We’re using this powerful word, but lowering the standard by having everybody be obsessed by everything.” (This jibes with a general culture of hyperbole on the Internet, where in an attempt to stand out from the noise, everything is the best. Thing. EVER!)

“It’s a gesture of self-promotion, innocent self-aggrandizement,” he said. “They’re compensating for not having the capacity to get all that interested in things. Younger people create an atmosphere of hysteria around themselves and get caught up in it.”

. “It’s basically a case of hyperbolic metaphorical extension — which is just a fancy way of saying it is fun to use over-the-top words about less-than-over-the-top things,” she said. “This is pretty common in English. ‘Awesome’ used to mean ‘inspiring awe’ and now it means, ‘That was a great burrito, dude.’ ”

We’ve gone from advertizing supporting journalism to journalism supporting corporate propaganda. At the rate we’re going, as the line between church and state is deliberately blurred by desperate media companies, we may end up with a handful of actual independent online magazines and newspapers and a vast industry of corporate propaganda designed to look like the real thing. If we’re lucky.

there’s that exquisite verse, one of the most beautiful in the Bible, the one that says if God cares deeply about sparrows, don’t you think He cares about you? One is so accustomed to dwelling on the second, human, half of the equation, the comforting part, but when you put your hand over that and consider only the first, it’s a little startling: God cares deeply about the sparrows. Not just that, He cares about them individually. “Are not five sparrows sold for two pennies?” Jesus says. “Yet not one of them is forgotten in God’s sight.”

The modern conversation on animal consciousness proceeds, with the rest of the Enlightenment, from the mind of René Descartes, whose take on animals was vividly (and approvingly) paraphrased by the French philosopher Nicolas Malebranche: they “eat without pleasure, cry without pain, grow without knowing it; they desire nothing, fear nothing, know nothing.” Descartes’ term for them was automata

In On the Origin of Species, Charles Darwin made the intriguing claim that among the naturalists he knew it was consistently the case that the better a researcher got to know a certain species, the more each individual animal’s actions appeared attributable to “reason and the less to unlearnt instinct.” The more you knew, the more you suspected that they were rational. That marks an important pivot, that thought, insofar as it took place in the mind of someone devoted to extremely close and meticulous study of living animals, a mind that had trained itself not to sentimentalize.

The sheer number and variety of experiments carried out in the twentieth century—and with, if anything, a renewed intensity in the twenty-first—exceeds summary. Reasoning, language, neurology, the science of emotions—every chamber where “consciousness” is thought to hide has been probed. Birds and chimps and dolphins have been made to look at themselves in mirrors—to observe whether, on the basis of what they see, they groom or preen (a measure, if somewhat arbitrary, of self-awareness). Dolphins have been found to grieve. Primates have learned symbolic or sign languages and then been interrogated with them. Their answers show thinking but have proved stubbornly open to interpretation on the issue of “consciousness,” with critics warning, as always, about the dangers of anthropomorphism, animal-rights bias, etc.

If we put aside the self-awareness standard—and really, how arbitrary and arrogant is that, to take the attribute of consciousness we happen to possess over all creatures and set it atop the hierarchy, proclaiming it the very definition of consciousness (Georg Christoph Lichtenberg wrote something wise in his notebooks, to the effect of: only a man can draw a self-portrait, but only a man wants to)—it becomes possible to say at least the following: the overwhelming tendency of all this scientific work, of its results, has been toward more consciousness. More species having it, and species having more of it than assumed.

The animal kingdom is symphonic with mental activity, and of its millions of wavelengths, we’re born able to understand the minutest sliver. The least we can do is have a proper respect for our ignorance.

The philosopher Thomas Nagel wrote an essay in 1974 titled, “What Is It Like To Be a Bat?”, in which he put forward perhaps the least overweening, most useful definition of “animal consciousness” ever written, one that channels Spinoza’s phrase about “that nature belonging to him wherein he has his being.” Animal consciousness occurs, Nagel wrote, when “there is something that it is to be that organism—something it is like for the organism.” The strangeness of his syntax carries the genuine texture of the problem. We’ll probably never be able to step far enough outside of our species-reality to say much about what is going on with them, beyond saying how like or unlike us they are. Many things are conscious on the earth, and we are one, and our consciousness feels like this; one of the things it causes us to do is doubt the existence of the consciousness of the other millions of species. But it also allows us to imagine a time when we might stop doing that.

on many important issues, civilization only destroys itself by extending the number of important operations that we can perform without thinking about them. On many issues, we want more thinking, not less.

Given that our online tools and platforms are built in a way to make our browsing experience as frictionless as possible, is it any surprise that so much of our personal information is disclosed without our ever realizing it?

Instead of having the designer think through all the moral and political implications of technology use before it reaches users — an impossible task — we must find a way to get users to do some of that thinking themselves.

most designers, following Wilde, think of technologies as nothing more than mechanical slaves that must maximize efficiency. But some are realizing that technologies don’t have to be just trivial problem-solvers: they can also be subversive troublemakers, making us question our habits and received ideas.

Recently, designers in Germany built devices — “transformational products,” they call them — that engage users in “conversations without words.” My favorite is a caterpillar-shaped extension cord. If any of the devices plugged into it are left in standby mode, the “caterpillar” starts twisting as if it were in pain. Does it do what normal extension cords do? Yes. But it also awakens users to the fact that the cord is simply the endpoint of a complex socio-technical system with its own politics and ethics. Before, designers have tried to conceal that system. In the future, designers will be obliged to make it visible.

Will such extra seconds of thought — nay, contemplation — slow down civilization? They well might. But who said that stopping to catch a breath on our way to the abyss is not a sensible strategy?

these three convictions do not include the belief that the specific teachings of the Catholic Church provide the fundamental truths of human life.  What I do believe is that these teachings are very helpful for understanding the human condition.  Here I distinguish three domains: metaphysical doctrines about the existence and nature of God, historical accounts from the Bible of how God has intervened in human history to reveal his truth and the ethics of love preached by Jesus.

The ethics of love I revere as the inspiration for so many (Catholics and others) who have led exemplary moral lives.  I don’t say that this ethics is the only exemplary way to live or that we have anything near to an adequate understanding of it.  But I know that it has been a powerful force for good. 

As to the theistic metaphysics, I’m agnostic about it taken literally, but see it as a superb intellectual construction that provides a fruitful context for understanding how our religious and moral experiences are tied to the ethics of love.  The historical stories, I maintain, are best taken as parables illustrating moral and metaphysical teachings.

I reverse this order, putting first the ethics of love as a teaching that directly captivates our moral sensibility, then taking the history and metaphysics as helpful elucidations of the ethics.

Catholicism too has reconciled itself to the Enlightenment view of religion.

First, the Church now explicitly acknowledges the right of an individual’s conscience in religious matters: No one may “be prevented from acting according to his conscience, especially in religious matters”  (“Catechism of the Catholic Church,” citing a decree from the Second Vatican Council).

Second, the Church, in practice, hardly ever excludes from its community those who identity themselves as Catholics but reinterpret central teachings (and perhaps reject less central ones).  The “faithful” who attend Mass, receive the sacraments, send their children to Catholic schools and sometimes even teach theology include many who hold views similar to mine.   Church leaders have in effect agreed that the right to follow one’s conscience includes the right of dissident Catholics to remain members of the Church.

there is deep disagreement within the Church about how its core doctrines, including those about the hierarchy’s authority, should be understood.  With the Second Vatican Council, the hierarchy began a move toward the liberal position, which the successors of John XXIII have tried to reverse.  But history shows that Catholics play in a very long game, and there is no reason to give up hope for a new blossoming of the liberal buds.

Critics outside the Church will ask how I adhere to an institution that has so many deep flaws.  My first response is that the Catholic tradition of thought and practice is the only stance toward religion that, in William James’s phrase, is a “live option” for me — the only place I feel at home.  Simply to renounce it would be, as I said at the outset, to lose my self-respect — to deny part of my moral core.

My second response is that the liberal drive for reform is the best hope of saving the Church.  Its greatest present danger is precisely the loss of the members whom the hierarchy and the rest of the conservative core want to marginalize.  I’m not willing to abandon the Church to them.

we can trace the major disasters of 20th century politics to the impeccably optimistic doctrines of Marx, Lenin, Mao, and the many others for whom progress was the inevitable tendency of history. Pessimism, so obviously vindicated in retrospect, is almost always ineffective at the time. Why is this?

Our approaches to questions of that kind have been strongly influenced in recent years by evolutionary psychology, which tells us that we are endowed with traits of character and patterns of feeling that were “adaptive” in the conditions from which human societies first emerged. And what was adaptive then might be profoundly maladaptive today, in the mass societies that we ourselves have created. It was adaptive in those small bands of hunter-gatherers to join the crowd, to persecute the doubter, to go cheerfully forward against the foe. And from these traits have sprung certain patterns of thinking that serve the vital purpose of preventing people from perceiving the truth, when the truth will discourage them.

Solutions to our leaky privacy system tend to focus on transparency and control — that our best hope is knowing what our data is being used for and choosing whether to participate. But a challenge to that conventional wisdom emerges in his research. Giving users control may be an essential step, but it may also be a bit of an illusion.

personal data is what fuels the barons of the Internet age. Mr. Acquisti investigates the trade-offs that users make when they give up that data, and who gains and loses in those transactions. Often there are immediate rewards (cheap sandals) and sometimes intangible risks downstream (identity theft). “

“The technologist in me loves the amazing things the Internet is allowing us to do,” he said. “The individual who cares about freedom is concerned about the technology being hijacked, from a technology of freedom into a technology of surveillance.”

EARLY in his sojourn in this country, Mr. Acquisti asked himself a question that would become the guiding force of his career: Do Americans value their privacy?

If we have something — in this case, ownership of our purchase data — we are more likely to value it. If we don’t have it at the outset, we aren’t likely to pay extra to acquire it. Context matters.

“What worries me,” he said, “is that transparency and control are empty words that are used to push responsibility to the user for problems that are being created by others.”

We are constantly asked to make decisions about personal data amid a host of distractions, like an e-mail, a Twitter notification or a text message. If Mr. Acquisti is correct, those distractions may hinder our sense of self-protection when it comes to privacy.

His latest weapon against distraction is an iPad application, which lets him create a to-do list every morning and set timers for each task: 30 minutes for e-mail, 60 minutes to grade student papers, and so on.

it is not surprising that he is cautious in revealing himself online. He says he doesn’t feel compelled to post a picture of his meals on Instagram. He uses different browsers for different activities. He sometimes uses tools that show which ad networks are tracking him. But he knows he cannot hide entirely, which is why some people, he says, follow a policy of “rational ignorance.”

The online advertising industry insists that the data is scrambled to make it impossible to identify individuals.

Mr. Acquisti offers a sobering counterpoint. In 2011, he took snapshots with a webcam of nearly 100 students on campus. Within minutes, he had identified about one-third of them using facial recognition software. In addition, for about a fourth of the subjects whom he could identify, he found out enough about them on Facebook to guess at least a portion of their Social Security numbers.

The point of the experiment was to show how easy it is to identify people from the rich trail of data they scatter around the Web, including seemingly harmless pictures. Facebook can be especially valuable for identity thieves, particularly when a user’s birth date is visible to the public.

Does that mean Facebook users should lie about their birthdays (and break Facebook’s terms of service)? Mr. Acquisti demurred. He would say only that there are “complex trade-offs” to be made. “I reveal my date of birth and hometown on my Facebook profile and an identity thief can reconstruct my Social Security number and steal my identity,” he said, “or someone can send me ‘happy birthday’ messages on the day of my birthday, which makes me feel very good.”

"The twenties were the highest peak of joy-related words that we see," he says. "They really were roaring." But then there came 1941, which, of course, marked the beginning of America's entry into World War II. It doesn't take a historian to see that peaks and valleys like these roughly mirror the major economic and social events of the century. "In 1941, sadness is at its peak," Bently says.

They weren't just novels or books about current events, Bentley says. Many were books without clear emotional content — technical manuals about plants and animals, for example, or automotive repair guides. "It's not like the change in emotion is because people are writing about the Depression, and people are writing about the war," he says. "There might be a little bit of that, but this is just, kind of, averaged over all books and it's just kind of creeping in."

Generally speaking the usage of these commonly known emotion words has been in decline over the 20th century," Bentley says. We used words that expressed our emotions less in the year 2000 than we did 100 years earlier — words about sadness, and joy, and anger, and disgust and surprise. In fact, there is only one exception that Bentley and his colleagues found: fear. "The fear-related words start to increase just before the 1980s," he says.

For psychologists, he says, there are only a handful of ways to try to understand what is actually going on with somebody emotionally. "One is what a person says," Pennebaker explains, "kind of the 'self report' of emotion. Another might be the physiological links, and the third is what slips out when they're talking to other people, when they're writing a book or something like that."

Other big thinkers believed that if people are left perfectly free to follow their desires, their baser ones will end up dominating their nobler ones. For these writers, the goal in life is not primarily to be free but to be good. Being virtuous often means thwarting your inclinations, obeying a power outside yourself. It means maintaining a balance between liberty and restraint, restricting freedom for the sake of an ordered existence.

Recently, the balance between freedom and restraint has been thrown out of whack. People no longer even have a language to explain why freedom should sometimes be limited. The results are as predicted. A decaying social fabric, especially among the less fortunate. Decline in marriage. More children raised in unsteady homes. Higher debt levels as people spend to satisfy their cravings.

who knows, maybe we’ll see other spheres in life where restraints are placed on maximum personal choice. Maybe there will be sumptuary codes that will make lavish spending and C.E.O. salaries unseemly. Maybe there will be social codes so that people understand that the act of creating a child includes a lifetime commitment to give him or her an organized home. Maybe voters will restrain their appetite for their grandchildren’s money. Maybe more straight people will marry.

The proponents of same-sex marriage used the language of equality and rights in promoting their cause, because that is the language we have floating around. But, if it wins, same-sex marriage will be a victory for the good life, which is about living in a society that induces you to narrow your choices and embrace your obligations.
