The popular left/right story has no solid basis in science. The brain doesn't work one part at a time, but rather as a single interactive system, with all parts contributing in concert, as neuroscientists have long known. The left brain/right brain story may be the mother of all urban legends: It sounds good and seems to make sense—but just isn't true.

There is a better way to understand the functioning of the brain, based on another, ordinarily overlooked anatomical division—between its top and bottom parts. We call this approach "the theory of cognitive modes." Built on decades of unimpeachable research that has largely remained inside scientific circles, it offers a new way of viewing thought and behavior

Our theory has emerged from the field of neuropsychology, the study of higher cognitive functioning—thoughts, wishes, hopes, desires and all other aspects of mental life. Higher cognitive functioning is seated in the cerebral cortex, the rind-like outer layer of the brain that consists of four lobes

Facebook’s new plan to host news publications’ stories directly is not only about page views, advertising revenue or the number of seconds it takes for an article to load. It is about who owns the relationship with readers.

It’s why Google, a search engine, started a social network and why Facebook, a social network, started a search engine. It’s why Amazon, a shopping site, made a phone and why Apple, a phone maker, got into shopping.

Facebook’s experiment, called instant articles, is small to start — just a few articles from nine media companies, including The New York Times. But it signals a major shift in the relationship between publications and their readers. If you want to read the news, Facebook is saying, come to Facebook, not to NBC News or The Atlantic or The Times — and when you come, don’t leave. (For now, these articles can be viewed on an iPhone running the Facebook app.)

knowledge from a scientific perspective of how human memory works can be instructive to historians.

Memory is much more than a simple retrieval system, as Dr. Schacter has demonstrated in his research. Rather, the nature of memory is constructive and influenced by a person’s current state as well as intervening emotions, beliefs, events and other factors since a recalled event.

Dr. Schacter is William R. Kenan, Jr. Professor of Psychology at Harvard University. His books include Searching for Memory: The Brain, The Mind, and The Past, and The Seven Sins of Memory: How the Mind Forgets and Remembers, both winners of the American Psychological Association’s William James Book Award, and Forgotten Ideas, Neglected Pioneers: Richard Semon and the Story of Memory. He also has written hundreds of articles on memory and related matters. He was elected a Fellow of the American Academy of Arts and Sciences in 1996 and the National Academy of Sciences in 2013.

an array of new discoveries in psychology and neuroscience has further demonstrated how our preexisting beliefs, far more than any new facts, can skew our thoughts and even color what we consider our most dispassionate and logical conclusions. This tendency toward so-called "motivated reasoning" helps explain why we find groups so polarized over matters where the evidence is so unequivocal: climate change, vaccines, "death panels," the birthplace and religion of the president (PDF), and much else. It would seem that expecting people to be convinced by the facts flies in the face of, you know, the facts.

The theory of motivated reasoning builds on a key insight of modern neuroscience (PDF): Reasoning is actually suffused with emotion (or what researchers often call "affect"). Not only are the two inseparable, but our positive or negative feelings about people, things, and ideas arise much more rapidly than our conscious thoughts, in a matter of milliseconds—fast enough to detect with an EEG device, but long before we're aware of it. That shouldn't be surprising: Evolution required us to react very quickly to stimuli in our environment. It's a "basic human survival skill," explains political scientist Arthur Lupia of the University of Michigan. We push threatening information away; we pull friendly information close. We apply fight-or-flight reflexes not only to predators, but to data itself.

reasoning comes later, works slower—and even then, it doesn't take place in an emotional vacuum. Rather, our quick-fire emotions can set us on a course of thinking that's highly biased, especially on topics we care a great deal about.

Is this a good thing, I wondered, or an epic waste of time?

Twitter devotees at The Times tell me the benefits are real. Twitter enables them to be better reporters, for one thing. By selecting a universe of tweeters to follow, they can track news sources of all kinds, including rival journalists. They can create listening posts across every topic they need to monitor.

I don’t read everything. I dip into Twitter when I have time. The analogy is a cocktail party. You can’t join every conversation, but you drift through the crowd and stop now and then.”

Carr argued that the ease of online searching and distractions of browsing through the web were possibly limiting his capacity to concentrate. "I'm not thinking the way I used to," he wrote, in part because he is becoming a skimming, browsing reader, rather than a deep and engaged reader. "The kind of deep reading that a sequence of printed pages promotes is valuable not just for the knowledge we acquire from the author's words but for the intellectual vibrations those words set off within our own minds. In the quiet spaces opened up by the sustained, undistracted reading of a book, or by any other act of contemplation, for that matter, we make our own associations, draw our own inferences and analogies, foster our own ideas.... If we lose those quiet spaces, or fill them up with ‘content,' we will sacrifice something important not only in our selves but in our culture."

force us to get smarter if we are to survive. "Most people don't realize that this process is already under way," he wrote. "In fact, it's happening all around us, across the full spectrum of how we understand intelligence. It's visible in the hive mind of the Internet, in the powerful tools for simulation and visualization that are jump-starting new scientific disciplines, and in the development of drugs that some people (myself included) have discovered let them study harder, focus better, and stay awake longer with full clarity." He argued that while the proliferation of technology and media can challenge humans' capacity to concentrate there were signs that we are developing "fluid intelligence-the ability to find meaning in confusion and solve new problems, independent of acquired knowledge." He also expressed hope that techies will develop tools to help people find and assess information smartly.

76% of the experts agreed with the statement, "By 2020, people's use of the internet has enhanced human intelligence; as people are allowed unprecedented access to more information they become smarter and make better choices. Nicholas Carr was wrong: Google does not make us stupid."

Tallis informs 60 people gathered in a Kent lecture hall that his talk will demolish two "pillars of unwisdom." The first, "neuromania," is the notion that to understand people you must peer into the "intracranial darkness" of their skulls with brain-scanning technology. The second, "Darwinitis," is the idea that Charles Darwin's evolutionary theory can explain not just the origin of the human species—a claim Tallis enthusiastically accepts—but also the nature of human behavior and institutions.

Aping Mankind argues that neuroscientific approaches to things like love, wisdom, and beauty are flawed because you can't reduce the mind to brain activity alone.

Stephen Cave, a Berlin-based philosopher and writer who has called Aping Mankind "an important work," points out that most philosophers and scientists do in fact believe "that mind is just the product of certain brain activity, even if we do not currently know quite how." Tallis "does both the reader and these thinkers an injustice" by declaring that view "obviously" wrong,

differences on Iran policy correspond to answers to this one question: Whether the world of 2015 is fundamentally similar to, or different from, the world of 1938.

the idea of recurring historic episodes has a powerful effect on decision-making in the here and now. Disagreements over policy often come down to the search for the right historic pattern to apply.

the idea that Europe on the eve of the Holocaust is the most useful guide to the world in 2015 runs through arguments about Iran policy. And if that is the correct model to apply, the right "picture in our heads" as Walter Lippmann put it in Public Opinion, then these conclusions naturally follow:

Baseball is a team sport, but it is basically an accumulation of individual activities. Throwing a strike, hitting a line drive or fielding a grounder is primarily an individual achievement. The team that performs the most individual tasks well will probably win the game.

In soccer, almost no task, except the penalty kick and a few others, is intrinsically individual. Soccer, as Simon Critchley pointed out recently in The New York Review of Books, is a game about occupying and controlling space. If you get the ball and your teammates have run the right formations, and structured the space around you, you’ll have three or four options on where to distribute it. If the defenders have structured their formations to control the space, then you will have no options. Even the act of touching the ball is not primarily defined by the man who is touching it; it is defined by the context created by all the other players.

Most of us spend our days thinking we are playing baseball, but we are really playing soccer. We think we individually choose what career path to take, whom to socialize with, what views to hold. But, in fact, those decisions are shaped by the networks of people around us more than we dare recognize.

In 1975, in “The Cook and the Cannibal,” Mr. Glucksmann subjected Marxism to a scalding critique. Two years later, he broadened his attack in his most influential work, “The Master Thinkers,” which drew a direct line from the philosophies of Marx, Hegel, Fichte and Nietzsche to the enormities of Nazism and Soviet Communism. It was they, he wrote in his conclusion, who “erected the mental apparatus which is indispensable for launching the grand final solutions of the 20th century.”

An instant best seller, the book put him in the company of several like-minded former radicals, notably Bernard-Henri Lévy and Pascal Bruckner. Known as the nouveaux philosophes, a term coined by Mr. Lévy, they became some of France’s most prominent public intellectuals, somewhat analogous to the neoconservatives in the United States, but with a lingering leftist orientation.

Their apostasy sent shock waves through French intellectual life, and onward to Moscow, which depended on the cachet afforded by Jean-Paul Sartre and other leftist philosophers

More 5inShare Email Print A defendant in the Atlanta Public Schools case turns herself in at the Fulton County Jail on April 2. (David Goldman/AP) Earlier this week at The Atlantic, Emily Richmond asked whether high-stakes testing caused the Atlanta schools cheating scandal. The answer, I would argue, is yes... just not in the way you might think. Tests don't cause unethical behavior. But they did cause the Atlanta cheating scandal, and they are doing damage to the teaching profession. The argument that tests do not cause unethical behavior is fairly straightforward, and has been articulated by a number of writers. Jonathan Chait quite correctly points out that unethical behavior occurs in virtually all professions -- and that it occurs particularly when there are clear incentives to succeed. Incentivizing any field increases the impetus to cheat. Suppose journalism worked the way teaching traditionally had. You get hired at a newspaper, and your advancement and pay are dictated almost entirely by your years on the job, with almost no chance of either becoming a star or of getting fired for incompetence. Then imagine journalists changed that and instituted the current system, where you can get really successful if your bosses like you or be fired if they don't. You could look around and see scandal after scandal -- phone hacking! Jayson Blair! NBC's exploding truck! Janet Cooke! Stephen Glass! -- that could plausibly be attributed to this frightening new world in which journalists had an incentive to cheat in order to get ahead. It holds true of any field. If Major League Baseball instituted tenure, and maybe used tee-ball rules where you can't keep score and everybody gets a chance to hit, it could stamp out steroid use. Students have been cheating on tests forever -- massive, systematic cheating, you could say. Why? Because they have an incentive to do well. Give teachers and administrators an incentive for their students to do well, and more of them will cheat. For Chait, then, teaching has just been made more like journalism or baseball; it has gone from an incentiveless occupation to one with incentives.

Chait refers to violations of journalistic ethics -- like the phone-hacking scandal -- and suggests they are analogous to Major-League steroid use, and that both are similar to teachers (or students) cheating on tests. But is phone hacking "cheating"

Phone hacking was, then, not an example of cheating. It was a violation of professional ethics. And those ethics are not arbitrarily imposed, but are intrinsic to the practice of journalism as a profession committed to public service and to truth.

Data mining, as Burdick’s book shows, is not new. But today’s social media companies do it more extensively and more efficiently.

Consider an imperfect but instructive analogy. Any campaign can acquire your listed landline number. But no campaign is permitted access to your hopes, fears, worries, passions or day-to-day business by way of a phone tap. Facebook’s accumulated information may not be quite like a tap. But the company sure knows a whole lot about you.

We must decide when Facebook and comparable companies should be held accountable as public utilities. And when do they look more like publishers who bear responsibility for the veracity of the “information” they spread around?

Ah, the tyranny of read receipts – enough to put you off digital communication for good.

It sounds straightforward enough, even perfunctory, and indeed it is if it’s only a blip in the back-and-forth. But when a message lingers on “seen” without explanation for anything beyond a few minutes, you’ve been “left on read”. It’s enough to make even the most self-assured individuals question their worth.

It works both ways, too: if you’ve read a message that you’re either unable or unwilling to respond to immediately, the countdown has already started.

the neuroscientific analogy: that the areas in the brain associated with the pleasures of drug use are the same as those associated with the pleasures of playing video games. This is true but not illuminating. These areas of the brain — those that produce and respond to the neurotransmitter dopamine — are involved in just about any pleasurable activity: having sex, enjoying a nice conversation, eating good food, reading a book, using methamphetamines.

A large-scale study of internet-based games recently published in the American Journal of Psychiatry bears out our skepticism about this “addiction.” Using the American Psychiatric Association’s own metrics for ascertaining psychiatric disorder, the study’s researchers found that at most 1 percent of video game players might exhibit characteristics of an addiction and that the games were significantly less addictive than, say, gambling.

More damning, the study found that almost none of those classified as being possibly addicted to video games experienced negative outcomes from this addiction. That is, the mental, physical and social health of these potential “addicts” was not different from that of individuals who were not addicted to video games. This suggests that the diagnosis of addiction doesn’t make much sense to begin with

have found evidence linking problems in the lymphatic and glymphatic systems to Alzheimer’s. In a study on mice, they showed that glymphatic dysfunction contributes to the buildup in the brain of amyloid beta, a protein that plays a key role in the disease.

several colleagues examined postmortem tissue from 79 human brains. They focused on aquaporin-4, a key protein in glymphatic vessels. In the brains of people with Alzheimer’s, this protein was jumbled; in those without the disease, the protein was well organized. This suggests that glymphatic breakdowns may play a role in the disease

The vessels have also been implicated in autoimmune disease. Researchers knew that the immune system has limited access to the brain. But at the same time, the immune system kept tabs on the brain’s status; no one knew exactly how. Some researchers theorize that the glymphatic system could be the conduit and that in diseases such as multiple sclerosis — where the body’s immune system attacks certain brain cells — the communication may go awry.

Who Is Still Buying VHS Tapes?

Why Did the Dean of the Most Diverse Law School in the Country Cancel Herself?

Was it the unfortunate use of a single word? Or something far more complicated?

Mary Lu Bilek, who has spent 32 years at the law school at the City University of New York, the past five of them as dean, sent an email to students and faculty with the subject line: “Apology.”

The separation of people from, and the superiority of people to, members of other species is a good candidate for the originating idea of Western thought. And a good candidate for the worst.

Like Plato, Hobbes associates anarchy with animality and civilization with the state, which gives to our merely animal motion moral content for the first time and orders us into a definite hierarchy.

It is rationality that gives us dignity, that makes a claim to moral respect that no mere animal can deserve. “The moral law reveals to me a life independent of animality,” writes Immanuel Kant in “Critique of Practical Reason.” In this assertion, at least, the Western intellectual tradition has been remarkably consistent.
