Mental labour can also be exhausting. Even resisting that last glistening chocolate-chip cookie after a long day at a consuming desk job is difficult. Cognitive control, the umbrella term encompassing mental exertion, self-control and willpower, also fades with effort.

unlike the mechanism of physical fatigue, the cause of cognitive fatigue has been poorly understood.

It posits that exerting cognitive control uses up energy in the form of glucose. At the end of a day spent intensely cogitating, the brain is metaphorically running on fumes. The problem with this version of events is that the energy cost associated with thinking is minimal.

Strategists affiliated with the Obama and Romney campaigns say they have access to information about the personal lives of voters at a scale never before imagined. And they are using that data to try to influence voting habits — in effect, to train voters to go to the polls through subtle cues, rewards and threats in a manner akin to the marketing efforts of credit card companies and big-box retailers.

In the weeks before Election Day, millions of voters will hear from callers with surprisingly detailed knowledge of their lives. These callers — friends of friends or long-lost work colleagues — will identify themselves as volunteers for the campaigns or independent political groups. The callers will be guided by scripts and call lists compiled by people — or computers — with access to details like whether voters may have visited pornography Web sites, have homes in foreclosure, are more prone to drink Michelob Ultra than Corona or have gay friends or enjoy expensive vacations.

“You don’t want your analytical efforts to be obvious because voters get creeped out,” said a Romney campaign official who was not authorized to speak to a reporter. “A lot of what we’re doing is behind the scenes.”

Victoria Sharp says she is certain LaVoy Finicum was unjustly gunned down by state police after they and the FBI pursued his vehicle in southern Oregon.

"I know what I saw."

Sharp said she heard three shots and saw Finicum fall

Just before leading the rally in the pledge, Trump once again opened the door to ordering the torture of captured suspected terrorists, just one day after vowing that he would not order military officials to violate U.S. or international laws.

"We're going to stay within the laws. But you know what we're going to do? We're going to have those laws broadened because we're playing with two sets of rules: their rules and our rules," Trump said pointing to ISIS's tactics, which have included torture and brutal executions.

The comments mark a stark contrast to a statement Trump issued just a day earlier. After vigorously defending the use of waterboarding and suggesting that the U.S. should "go a lot further than waterboarding," Trump vowed Friday in a statement that he would "not order our military or other officials to violate those laws."

You might claim to sympathize with the pain experienced by a higher status person, but it's quite likely your jealous brain would actually turn a neural blind eye.

The participants reported that they'd felt equal amounts of empathy and discomfort when the other players underwent the horrible needle treatment, regardless of whether those players were one-star or three-star. But looking at the participants' brain activity told a rather different story.

When they observed photos of an inferior one-star player undergoing the needle injection, their brains showed increased activity in two key brain areas that are known to be involved in feeling pain and in representing the pain of others

There are two brain networks, called in the literature the “Default Mode Network” and the “Task Positive Network” – and it was shown these activate in different reasoning situations, but rarely together. One network lit up when subjects were asked to reason about physical systems (including the mechanical properties of inanimate objects); the other lit up when subjects were asked to reason about social situations (including the mental states of other people).

Some people have jumped to bad conclusions on the basis of this evidence, claiming that it shows “analytic thinking” and “empathy” are in tension, and that when we reason carefully, we can’t see the human cost of our decisions.

These are all open questions where the logician, the linguist and the philosopher enter the picture, to help us understand how we can represent and reason about the world.

the act of formulating questions enables us “to organize our thinking around what we don’t know.” This makes questioning a good skill to hone in dynamic times.

Asking questions can help spark the innovative ideas that many companies hunger for these days

By the time we’re in the workplace, many of us have gotten out of the habit of asking fundamental questions about what’s going on around us. And some people worry that asking questions at work reveals ignorance or may be seen as slowing things down.

THE problem is that a math model, like a metaphor, is a simplification. This type of modeling came out of the sciences, where the behavior of particles in a fluid, for example, is predictable according to the laws of physics.

In so many Big Data applications, a math model attaches a crisp number to human behavior, interests and preferences. The peril of that approach, as in finance, was the subject of a recent book by Emanuel Derman, a former quant at Goldman Sachs and now a professor at Columbia University. Its title is “Models. Behaving. Badly.”

A report last year by the McKinsey Global Institute, the research arm of the consulting firm, projected that the United States needed 140,000 to 190,000 more workers with “deep analytical” expertise and 1.5 million more data-literate managers, whether retrained or hired.

Every culture ever studied has been found to make music, and among the oldest artistic objects known are slender flutes carved from mammoth bone some 43,000 years ago — 24,000 years before the cave paintings of Lascaux.

, many researchers had long assumed that the human brain must be equipped with some sort of music room, a distinctive piece of cortical architecture dedicated to detecting and interpreting the dulcet signals of song. Yet for years, scientists failed to find any clear evidence of a music-specific domain through conventional brain-scanning technology

devised a radical new approach to brain imaging that reveals what past studies had missed. By mathematically analyzing scans of the auditory cortex and grouping clusters of brain cells with similar activation patterns, the scientists have identified neural pathways that react almost exclusively to the sound of music — any music. It may be Bach, bluegrass, hip-hop, big band, sitar or Julie Andrews. A listener may relish the sampled genre or revile it. No matter. When a musical passage is played, a distinct set of neurons tucked inside a furrow of a listener’s auditory cortex will fire in response.Other sounds, by contrast — a dog barking, a car skidding, a toilet flushing — leave the musical circuits unmoved.

IQ test scores had significantly risen from one generation to the nex

widespread increase in IQ scores, and reveals some new ones, regarding teenagers’ vocabularies and the mental decline of the extremely bright in old age. Ultimately, Flynn concludes that human beings are not smarter—just more modern

there is a subtest called “similarities,” which asks questions like, what do dogs and rabbits have in common? Or what do truth and beauty have in common? On this subtest, the gains over those 50 years have been quite extraordinary, something like 25 points. The arithmetic subtest essentially tests arithmetical reasoning, and on that, the gains have been extremely small.

Memory’s speed and accuracy begin to slip around age 25 and keep on slipping.

Now comes a new kind of challenge to the evidence of a cognitive decline, from a decidedly digital quarter: data mining, based on theories of information processing

Since educated older people generally know more words than younger people, simply by virtue of having been around longer, the experiment simulates what an older brain has to do to retrieve a word. And when the researchers incorporated that difference into the models, the aging “deficits” largely disappeared.

we need a new way of thinking about our informational milieu. What we need is a concept of infopolitics that would help us understand the increasingly dense ties between politics and information

Infopolitics encompasses not only traditional state surveillance and data surveillance, but also “data analytics” (the techniques that enable marketers at companies like Target to detect, for instance, if you are pregnant), digital rights movements (promoted by organizations like the Electronic Frontier Foundation), online-only crypto-currencies (like Bitcoin or Litecoin), algorithmic finance (like automated micro-trading) and digital property disputes (from peer-to-peer file sharing to property claims in the virtual world of Second Life)

Surveying this iceberg is crucial because atop it sits a new kind of person: the informational person. Politically and culturally, we are increasingly defined through an array of information architectures: highly designed environments of data, like our social media profiles, into which we often have to squeeze ourselves

It is possible to examine any object—including a brain—at different levels

if we want to know how the brain gives rise to thoughts, feelings, and behaviors, we want to focus on the bigger picture of how its structure allows it to store and process information—the architecture, as it were. To understand the brain at this level, we don’t have to know everything about the individual connections among brain cells or about any other biochemical process.

top parts and the bottom parts of the brain have differ­ent functions. The top brain formulates and executes plans (which often involve deciding where to move objects or how to move the body in space), whereas the bottom brain classifies and interprets incoming information about the world. The two halves always work together;

Over the past two weeks, Mr. Grunberg has spent several hours a day writing his novella, while a battery of sensors and cameras tracked his brain waves, heart rate, galvanic skin response (an electrical measure of emotional arousal) and facial expressions. Next fall, when the book is published, some 50 ordinary people in the Netherlands will read it under similarly controlled circumstances, sensors and all.

Researchers will then crunch the data in the hope of finding patterns that may help illuminate links between the way art is created and enjoyed, and possibly the nature of creativity itself.

the burgeoning field of neuroaesthetics, which over the last decade or so has attempted to uncover the neural underpinnings of our experience of music and visual art, using brain imaging technology. Slowly, a small but growing number of researchers have also begun using similar tools to scrutinize the perhaps more elusive, and perhaps endangered, experience of literary reading.

kea’s investigations were conducted for various reasons, including the vetting of job applicants, efforts to build cases against employees accused of wrongdoing, and even attempts to undermine the arguments of consumers bringing complaints against the company. The going rate charged by the private investigators was 80 to 180 euros, or $110 to $247, per inquiry, court documents show. Between 2002 and 2012, the finance department of Ikea France approved more than €475,000 in invoices from investigators.

the spying cases occurred in a country that, in the digital age, has elevated privacy to a level nearly equal to the national trinity of Liberté, Égalité and Fraternité.

Last month, the company’s current chief, Stefan Vanoverbeke, and financial director, Dariusz Rychert, were questioned along with Mr. Baillot for 48 hours by the judicial police before being placed under formal investigation. That set in motion a process in which the next step, if it comes, would be the filing of criminal charges.

Every time a research paper about violent video games makes it into the news, it feels like we’re in a time loop. Any claims that the study makes about the potential positive or (usually) negative effects of playing games tend to get over-egged to the point of ridiculousness.

At best, the measures of aggression that are used in such work are unstandardised; at worst, the field has been shown to be riddled with basic methodological and analytical flaws. These problems are further compounded by entrenched ideologies and a reluctance from some researchers to even talk to their ‘adversaries’, let alone discuss the potential for adversarial collaborations

All of this means that we’re stuck at an impasse with violent video games research; it feels like we’re no more clued up on what the actual behavioural effects are now than, say, five or ten years ago.

Simone's mom reads, sings and talks to him in French.

The goal? To raise him to be bilingual.

If you've ever thought about raising your kid to be multilingual, now's the perfect time to start. "Babies are wired for language,"

On April 8, 1966, Time magazine carried a lead story for which the cover was completely black except for three words emblazoned in bright, red letters against the dark background: “IS GOD DEAD?” The story described the so-called ‘Death of God’ movement then current in American theology. But, to paraphrase Mark Twain, it seemed that the news of God’s demise was “greatly exaggerated.” For at the same time that theologians were writing God’s obituary, a new generation of young philosophers was re-discovering His vitality.

Back in the 1940s and ’50s it was widely believed among philosophers that any talk about God is meaningless, since it is not verifiable by the five senses.

Its downfall meant a resurgence of metaphysics, along with other traditional problems of philosophy which Verificationism had suppressed. Accompanying this resurgence came something altogether unanticipated: a renaissance of Christian philosophy.

data-driven style of politics is built on a questionable philosophy and a set of dubious assumptions. Data-driven politics is built on a philosophy you might call Impersonalism. This is the belief that what matters in politics is the reaction of populations and not the idiosyncratic judgment, moral character or creativity of individuals.

Data-driven politics assumes that demography is destiny, that the electorate is not best seen as a group of free-thinking citizens but as a collection of demographic slices.

This method assumes that mobilization is more important than persuasion; that it is more important to target your likely supporters than to try to reframe debates or persuade the whole country.
