Turning Point: Apple resists the F.B.I. in unlocking an iPhone in the San Bernardino terrorism case.

Privacy confuses me, beyond my simplest understanding, which is that individuals prefer, to different degrees, that information about them not be freely available to others.

What does it mean, in an ostensible democracy, for the state to keep secrets from its citizens? The idea of the secret state seems antithetical to democracy, since its citizens, the voters, can’t know what their government is doing.

Now Ms. Hopewell, 37, is ebullient, and full of smiles, hugs and laughs. After spending the last three and a half years studying forensic psychology at the John Jay College of Criminal Justice in Midtown, it was official: She was a college graduate, the first in her family.

“But at the end of the day I know it’s beneficial for my family and I want bigger and better things, and I have to do it.”

I want to leave a legacy for my kids when I leave this earth, and living paycheck to paycheck is not going to get it.

According to paratroopers, stunt professionals, physical therapists and martial arts instructors, there is indeed a “right way” to fall — and it can save you a lot of grief if you know how to do it.

The Agency for Healthcare Research and Quality estimates that falls cause more than a third of injury-related emergency room visits, around 7.9 million a year.

Moreover, falling straight forward or backward raises the risk of damaging your spine and vital organs.

they write that eye contact actually "disrupts resources available to cognitive control processes during verb generation." In other words, when you need to come up with certain words under certain circumstances, maintaining eye contact depletes the very brain resources you need to find the word.

but Scientific American suggests that if looking away while thinking is cross-cultural, "perhaps cultures with less emphasis on eye contact enable deeper thinking during a given conversation."

"A lot of the regulation of research ethics hinges on government supported research, and of course Facebook's research is not government supported, so they're not obligated by any laws or regulations to abide by the standards,"

many universities and research institutions and even for-profit companies use the Common Rule as a guideline anyway. It's voluntary. You could imagine if you were a drug company, you'd want to be able to say you'd done the research ethically because the backlash would be just huge otherwise."

The backlash, in this case, seems tied directly to the sense that Facebook manipulated people—used them as guinea pigs—without their knowledge, and in a setting where that kind of manipulation feels intimate

social networking sites create pressure to put time and effort into tending weak ties, and how it can be impossible to keep up with them all. Personally, I also find it difficult to keep up with my strong ties. I’m a great “pick up where we left off” friend, as are most of the people closest to me (makes sense, right?). I’m decidedly sub-awesome, however, at being in constant contact with more than a few people at a time.

the devolution of friendship. As I explain over the course of this essay, I link the devolution of friendship to—but do not “blame” it on—the affordances of various social networking platforms, especially (but not exclusively) so-called “frictionless sharing” features.

I’m using the word here in the same way that people use it to talk about the devolution of health care. One example of devolution of health care is some outpatient surgeries: patients are allowed to go home after their operations, but they still require a good deal of post-operative care such as changing bandages, irrigating wounds, administering medications, etc. Whereas before these patients would stay in the hospital and nurses would perform the care-labor necessary for their recoveries, patients must now find their own caregivers (usually family members or friends; sometimes themselves) to perform free care-labor. In this context, devolution marks the shift of labor and responsibility away from the medical establishment and onto the patient; within the patient-medical establishment collaboration, the patient must now provide a greater portion of the necessary work. Similarly, in some ways, we now expect our friends to do a greater portion of the work of being friends with us.

The coal industry knows that to stop runaway climate change all coal-powered generators need to close Australia joined 174 countries and the European Union in 2015, signing the Paris agreement. In doing so, Australia agreed to do its part in keeping the global temperature rise “well below” 2C.

According to data from the Office of the Chief Economist, the demand for coal-generated electricity has dropped by more than 15% in the past eight years.

Coal is now the most expensive form of new power. According to Bloomberg New Energy Finance, the cost of energy from a new coal power plant would be $134-$203/MWh. That’s more expensive than wind, solar or highly efficient combined-cycle gas (costing $61-$118/MWh, $78-$140/MWh and $74-$90/MWh, respectively).

But what is its evolutionary purpose – what kind of changes do our brains undergo when we sleep?

suggest our brains undergo a pruning cycle while we rest.

Its important to note these studies are still in their early stages. The tests were done on mice.

But after seeing ads from Coca-Cola, Procter & Gamble and Wal-Mart appear next to racist, anti-Semitic or terrorist videos, its engineers realized their computer models had a blind spot: They did not understand context.

Now teaching computers to understand what humans can readily grasp may be the key to calming fears among big-spending advertisers that their ads have been appearing alongside videos from extremist groups and other offensive messages.

But the recent problems opened Google to criticism that it was not doing enough to look out for advertisers. It is a significant problem for a multibillion-dollar company that still gets most of its revenue through advertising.

Such skills come from accumulated knowledge which benefits from a lifetime of experience. 

Vocabulary, in fact, peaked even later, in the late 60s to early 70s. So now you know why grandpa is so good at crosswords.

And here’s a win for the 40+ folks - the below representation of a test of 10,000 visitors to TestMyBrain.org shows that older subjects did better than the young on the vocabulary test.

I never allowed myself to be vulnerable with my husband because I didn’t realize that it was a requirement for an intimate, connected relationship. Back then, I didn’t even know what an intimate, connected relationship was. I only thought in terms of tasks and achievements.

Surely, I had thought, my firefighter boyfriend would wait an hour or two for me without complaint. But if he had, would we still be together today?

It has been said that we teach people how to treat us.

SAN FRANCISCO — Fingerprint sensors have turned modern smartphones into miracles of convenience.

While such wizardry is convenient, it has also left a gaping security hole.

Still, the findings raise troubling questions about the effectiveness of fingerprint security on smartphones.

There is an old adage, “take stock of the company you keep”.

As it turns out, we are more tolerant of people who have similar negative personality traits as us.

This tendency was strongest, however, in one trait above all: antagonism. With the connection being most prominent for the the trifecta of narcissism, psychopathy, and Machiavellianism.

one theme emerges from the media coverage of people's relationships with our current set of technologies: Consumers want digital willpower. App designers in touch with the latest trends in behavioral modification--nudging, the quantified self, and gamification--and good old-fashioned financial incentive manipulation, are tackling weakness of will. They're harnessing the power of payouts, cognitive biases, social networking, and biofeedback. The quantified self becomes the programmable self.

the trend still has multiple interesting dimensions

Individuals are turning ever more aspects of their lives into managerial problems that require technological solutions. We have access to an ever-increasing array of free and inexpensive technologies that harness incredible computational power that effectively allows us to self-police behavior everywhere we go. As pervasiveness expands, so does trust.

“Fifteen-year-old students whose parents often read books with them during their first year of primary school show markedly higher scores in PISA 2009 than students whose parents read with them infrequently or not at all. The performance advantage among students whose parents read to them in their early school years is evident regardless of the family’s socioeconomic background. Parents’ engagement with their 15-year-olds is strongly associated with better performance in PISA.”

“students whose parents reported that they had read a book with their child ‘every day or almost every day’ or ‘once or twice a week’ during the first year of primary school have markedly higher scores in PISA 2009 than students whose parents reported that they had read a book with their child ‘never or almost never’ or only ‘once or twice a month.’ On average, the score difference is 25 points, the equivalent of well over half a school year.”

“even when comparing students of similar socioeconomic backgrounds, those students whose parents regularly read books to them when they were in the first year of primary school score 14 points higher, on average, than students whose parents did not.”

Just as vigorous exercise tires our bodies, intellectual exertion should drain the brain. What the latest science reveals, however, is that the popular notion of mental exhaustion is too simplistic. The brain continuously slurps up huge amounts of energy for an organ of its size, regardless of whether we are tackling integral calculus or clicking through the week's top 10 LOLcats. Although firing neurons summon extra blood, oxygen and glucose, any local increases in energy consumption are tiny compared with the brain's gluttonous baseline intake. So, in most cases, short periods of additional mental effort require a little more brainpower than usual, but not much more.

something must explain the feeling of mental exhaustion, even if its physiology differs from physical fatigue. Simply believing that our brains have expended a lot of effort might be enough to make us lethargic.

a typical adult human brain runs on around 12 watts—a fifth of the power required by a standard 60 watt lightbulb. Compared with most other organs, the brain is greedy; pitted against man-made electronics, it is astoundingly efficient. IBM's Watson, the supercomputer that defeated Jeopardy! champions, depends on ninety IBM Power 750 servers, each of which requires around one thousand watts.

While philosophers, economists, and social scientists had assumed for centuries that human beings are rational agents—reason was our Promethean gift—Kahneman, the late Amos Tversky, and others, including Shane Frederick (who developed the bat-and-ball question), demonstrated that we’re not nearly as rational as we like to believe.

When people face an uncertain situation, they don’t carefully evaluate the information or look up relevant statistics. Instead, their decisions depend on a long list of mental shortcuts, which often lead them to make foolish decisions.

in many instances, smarter people are more vulnerable to these thinking errors. Although we assume that intelligence is a buffer against bias—that’s why those with higher S.A.T. scores think they are less prone to these universal thinking mistakes—it can actually be a subtle curse.

Once considered the product of genius or divine inspiration, creativity — the ability to spot problems and devise smart solutions — is being recast as a prized and teachable skill.

“The reality is that to survive in a fast-changing world you need to be creative,”

“That is why you are seeing more attention to creativity at universities,” he says. “The marketplace is demanding it.”

"Humans," she writes, "do not hold a positivity bias on account of having read too many self-help books. Rather, optimism may be so essential to our survival that it is hardwired into our most complex organ, the brain."

It takes rational reasoning hostage, directing our expectations toward a better outcome without sufficient evidence to support such a conclusion.

Optimism starts with what may be the most extraordinary of human talents: mental time travel. That is, the ability to move back and forth through time and space in one's mind. To think positively about our prospects, it helps to be able to imagine ourselves in the future. Although most of us take this ability for granted, our capacity to envision a different time and place is critical for our survival. It allows us to plan ahead, to save food and resources for times of scarcity, and to endure hard work in anticipation of a future reward.

Amazon is a global superstore, like Walmart. It’s also a hardware manufacturer, like Apple, and a utility, like Con Edison, and a video distributor, like Netflix, and a book publisher, like Random House, and a production studio, like Paramount, and a literary magazine, like The Paris Review, and a grocery deliverer, like FreshDirect, and someday it might be a package service, like U.P.S. Its founder and chief executive, Jeff Bezos, also owns a major newspaper, the Washington Post. All these streams and tributaries make Amazon something radically new in the history of American business

Amazon is not just the “Everything Store,” to quote the title of Brad Stone’s rich chronicle of Bezos and his company; it’s more like the Everything. What remains constant is ambition, and the search for new things to be ambitious about.

It wasn’t a love of books that led him to start an online bookstore. “It was totally based on the property of books as a product,” Shel Kaphan, Bezos’s former deputy, says. Books are easy to ship and hard to break, and there was a major distribution warehouse in Oregon. Crucially, there are far too many books, in and out of print, to sell even a fraction of them at a physical store. The vast selection made possible by the Internet gave Amazon its initial advantage, and a wedge into selling everything else.
