In support of that idea, half a dozen Nobel laureates and other prominent scientists are working with two small companies offering NR supplements.

This time his lab made headlines by reporting that the mitochondria in muscles of elderly mice were restored to a youthful state after just a week of injections with NMN (nicotinamide mononucleotide), a molecule that naturally occurs in cells and, like NR, boosts levels of NAD.

It should be noted, however, that muscle strength was not improved in the NMN-treated mice

a single dose of NR resulted in statistically significant increases” in NAD in humans—the first evidence that supplements could really boost NAD levels in people.

When NAD levels drop, as they do with aging, SIRT1 activity falls off, which in turn makes the crucial signals fade, leading to mitochondrial dysfunction and all the ill effects that go with it.

NAD boosters might work synergistically with supplements like resveratrol to help reinvigorate mitochondria and ward off diseases of aging

Test-tube and rodent studies also suggest that pterostilbene is more potent than resveratrol when it comes to improving brain function, warding off various kinds of cancer and preventing heart disease.

Even before Sinclair's paper, researchers had shown in 2012 that when given doses of NR, mice on high-fat diets gained 60 percent less weight than they did on the same diets without NR. Further, none of the mice on NR showed signs of diabetes, and their energy levels improved. The scientists reportedly characterized NR's effects on metabolism as "nothing short of astonishing."

Sleep deprivation has consequences for cognitive function, namely for attention and memory, two of the most crucial functions for any medical student.

If drinking alcohol before an exam is ludicrous, shouldn't an all-nighter be too?

The Institute of Medicine estimates that 50 to 70 million U.S. adults have a sleep or wakefulness disorder

If we do not find ways to make time for sleep now, we will face greater difficulty in finding balance when the hours become more demanding in our clinical years, in residency, and beyond.

"If sleep does not serve an absolutely vital function, then it is the biggest mistake the evolutionary process ever made."

Jobs reports reveal key economic indicators, and thus this one will likely influence the Federal Reserve’s decision making  at the next Federal Open Market Committee meeting on June 14.

Some companies provide paid leave anyway. In the last year, high-profile employers like Facebook and Goldman Sachs introduced or expanded paid leave for their employees.

But Clinton’s proposal differs from the bill in one crucial way. In order to finance the replacement wages that workers would get, the Gillibrand-DeLauro bill would impose a small payroll tax, of 0.4 percent, that employers and employees would split evenly.

Clinton has criticized that approach repeatedly because it would mean higher taxes on lower- and middle-income workers.

Sen. Marco Rubio (R-Fla.), the only Republican presidential candidate to address the issue formally, has said he’d offer small tax breaks to companies that offer paid leave -- an approach unlikely to have much impact, except perhaps to help well-off workers.

“The benefit of being one of the last countries in the world to adopt paid maternity leave is that we have been able to learn from other countries' experiences and the results are clear,” Betsey Stevenson, a University of Michigan economist and former adviser to President Barack Obama, told the Huffington Post on Thursday.

To advocates like Heather Boushey, chief economist and executive director of the Washington Center for Equitable Growth, that’s a welcome sign that American politics is finally talking about the challenges of parents who also have jobs.

"hate the infidels,"

when I first asked Ismoil about ISIS after the Paris attacks, he asked me one question back: "Why do you think they did it?" I responded with the only thing I knew: "They hate us."

He said that to resolve the conflicts between extremists in the Middle East and the West, it was important to talk "human to human," but he also made it clear that he empathizes at least somewhat with the Islamic State. Unsurprisingly, many of his views would be considered appalling to the vast majority of Americans, but our conversation gave me a window into the worldview of people who think the US is to blame for terrorism.

ISIS is not jihadists recruited from all over to fight. They are the Sunni Muslims that have lived through 25 years of wars, torture, and rapes. They are the Iraqi and Syrian people that have suffered from unjust wars started by the US government. And when the US government [mostly pulled out of] Iraq in 2010, the Shia and Maliki government started killing the Sunni day and night under the watch of the Americans.

You don't have to recruit people for ISIS. They're Muslims from all over the world that have seen an injustice after 25 years and want to help their brothers. What you have to understand is the Iraqi people are the most stubborn of the Muslim world. They won't accept occupation or humiliation.

People over in America ask why ISIS did this. [But] people in the Middle East ask, "Why is the US doing this to us?" Put yourself in their shoes—France is dropping bombs for a year in Iraq and [more recently] Syria, destroying everything, women, children, buildings... A bomb doesn't discriminate between ISIS or women and children—it just destroys.

Imagine the Iraq and Syrian people. After a year of bombing, you see your people killed, land destroyed, children scared to do anything more than hide in the corners all day. All this coming from bombs in the sky and you can't stop it. What would you do?

So, the question should be who is the first to be blamed? Tell both sides of the story.

My religion prohibits attacks on civilians. Unfortunately, many Muslims don't know much about Islam

What about the Planned Parenthood attack?What this man did is worse then what the doctors do. If this is what he's angry at, taking life, he did worse. Islam doesn't believe in abortion—all life is precious....[But] what he did was kill adult people who are grown. How is he trying to solve the issue?

For every action, there's a reaction. If you throw a ball against a wall, it's going to come back at you. If you throw a ball hard, it's going to come back at you hard. This is the problem with all sides in these wars. We hit you, you hit back. We hit you hard, you hit back harder. Back and forth, back and forth. Nobody wins. Both sides end up with death and destruction.

The Arabs are not radicalizing themselves. Your government action is radicalizing the Arabs

The only thing that keeps us just is Islam. Because in Islam, the peace, the justice, comes from the sky. The one who created earth and man, he knows best.

To solve the problem from the root, everyone has to become human. They need to talk, human to human. Let the people decide what they want. Leave them alone. Everyone can come together and say enough is enough. How long are we going to keep this action up? For the rest of our lives?It's the law of the jungle that we're living in right now. We were given more sense than this. We walk on two legs, with our heads high. But right now, we are walking with our heads down. We need to lift our heads up, and use the brains God created for us.

Egypt signed a deal to buy $1 billion of French weapons, as well as agreeing to commercial agreements.

As a result we end up with the most bizarre health-insurance system imaginable: One ever better designed to avoid sick people.

America’s giant health insurers are now busily consolidating into ever-larger behemoths.

In reality, they’re becoming huge to get more bargaining leverage over everyone they do business with — hospitals, doctors, employers, the government and consumers. That way they make even bigger profits.

researchers found, for example, that after Aetna merged with Prudential HealthCare in 1999, premiums rose 7 percent higher than had the merger not occurred.

The real choice in the future is either a hugely expensive for-profit oligopoly with the market power to charge high prices even to healthy people and stop insuring sick people.

Or else a government-run single payer system — such as is in place in almost every other advanced economy — dedicated to lower premiums and better care for everyone.

2) He will say whatever feels most comfortable or good to him at any given time. He will lie a lot, and say totally different things to different people. Stop being surprised by this. While it’s important to pretend “good faith” and remind him of promises, as Bernie Sanders and others are doing, that’s for his supporters, so *they* can see the inconsistency as it comes. He won’t care. So if you’re trying to reconcile or analyze his words, don’t. It’s 100% not worth your time. Only pay attention to and address his actions.

3) You can influence him by making him feel good. There are already people like Bannon who appear ready to use him for their own ends. The GOP is excited to try. Watch them, not him.

4) Entitlement is a key aspect of the disorder. As we are already seeing, he will likely not observe traditional boundaries of the office. He has already stated that rules don’t apply to him. This particular attribute has huge implications for the presidency and it will be important for everyone who can to hold him to the same standards as previous presidents.

5) We should expect that he only cares about himself and those he views as extensions of himself, like his children. (People with NPD often can’t understand others as fully human or distinct.) He desires accumulation of wealth and power because it fills a hole.

He will have no qualms *at all* about stealing everything he can from the country, and he’ll be happy to help others do so, if they make him feel good. He won’t view it as stealing but rather as something he’s entitled to do. This is likely the only thing he will intentionally accomplish.

6) It’s very, very confusing for non-disordered people to experience a disordered person with NPD. While often intelligent, charismatic and charming, they do not reliably observe social conventions or demonstrate basic human empathy. It’s very common for non-disordered people to lower their own expectations and try to normalize the behavior. DO NOT DO THIS

7) People with NPD often recruit helpers, referred to in the literature as “enablers” when they allow or cover for bad behavior and “flying monkeys” when they perpetrate bad behavior

8) People with NPD often foster competition for sport in people they control. Expect lots of chaos, firings and recriminations. He will probably behave worst toward those closest to him, but that doesn’t mean (obviously) that his actions won’t have consequences for the rest of us. He will punish enemies.

9) Gaslighting — where someone tries to convince you that the reality you’ve experienced isn’t true — is real and torturous. He will gaslight, his followers will gaslight.

Learn the signs and find ways to stay focused on what you know to be true. Note: it is typically not helpful to argue with people who are attempting to gaslight. You will only confuse yourself. Just walk away.

10) Whenever possible, do not focus on the narcissist or give him attention. Unfortunately we can’t and shouldn’t ignore the president, but don’t circulate his tweets or laugh at him — you are enabling him and getting his word out.

“Over 100 likes is good, for me. And comments. You just comment to make a joke or tag someone.”

The best thing is the little notification box, which means someone liked, tagged or followed her on Instagram. She has 604 followers. There are only 25 photos on her page because she deletes most of what she posts. The ones that don’t get enough likes, don’t have good enough lighting or don’t show the coolest moments in her life must be deleted.

Sociologists, advertisers, stock market analysts – everyone wants to know what happens when the generation born glued to screens has to look up and interact with the world.

“It kind of, almost, promotes you as a good person. If someone says, ‘tbh you’re nice and pretty,’ that kind of, like, validates you in the comments. Then people can look at it and say ‘Oh, she’s nice and pretty.’ ”

School is where she thrives: She is beloved by her teachers, will soon star as young Simba in the eighth-grade performance of “The Lion King” musical, and gets straight A’s. Her school doesn’t offer a math course challenging enough for her, so she takes honors algebra online through Johns Hopkins University.

“Happy birthday posts are a pretty big deal,” she says. “It really shows who cares enough to put you on their page.”

He checks the phone bill to see who she’s called and how much she’s been texting, but she barely calls anyone and chats mostly through Snapchat, where her messages disappear.

Some of Katherine’s very best friends have never been to her house, or she to theirs. To Dave, it seems like they rarely hang out, but he knows that to her, it seems like they’re together all the time.

Dave Pommerening wants to figure out how to get her to use it less. One month, she ate up 18 gigabytes of data. Most large plans max out at 10. He intervened and capped her at four GB. “I don’t want to crimp it too much,” he says. “That’s something, from my perspective, I’m going to have to figure out, how to get my arms around that.”

Even if her dad tried snooping around her apps, the true dramas of teenage girl life are not written in the comments. Like how sometimes, Katherine’s friends will borrow her phone just to un-like all the Instagram photos of girls they don’t like. Katherine can’t go back to those girls’ pages and re-like the photos because that would be stalking, which is forbidden.

Or how last week, at the middle school dance, her friends got the phone numbers of 10 boys, but then they had to delete five of them because they were seventh-graders. And before she could add the boys on Snapchat, she realized she had to change her username because it was her childhood nickname and that was totally embarrassing.

Then, because she changed her username, her Snapchat score reverted to zero. The app awards about one point for every snap you send and receive. It’s also totally embarrassing and stressful to have a low Snapchat score. So in one day, she sent enough snaps to earn 1,000 points.

Snapchat is where flirting happens. She doesn’t know anyone who has sent a naked picture to a boy, but she knows it happens with older girls, who know they have met the right guy.

Nothing her dad could find on her phone shows that for as good as Katherine is at math, basketball and singing, she wants to get better at her phone. To be one of the girls who knows what to post, how to caption it, when to like, what to comment.

Katherine doesn’t need magazines or billboards to see computer-perfect women. They’re right on her phone, all the time, in between photos of her normal-looking friends. There’s Aisha, there’s Kendall Jenner’s butt. There’s Olivia, there’s YouTube star Jenna Marbles in lingerie.

The whole world is at her fingertips and has been for years. This, Katherine offers as a theory one day, is why she doesn’t feel like she’s 13 years old at all. She’s probably, like, 16.

“I don’t feel like a child anymore” she says. “I’m not doing anything childish. At the end of sixth grade” — when all her friends got phones and downloaded Snapchat, Instagram and Twitter — “I just stopped doing everything I normally did. Playing games at recess, playing with toys, all of it, done.”

Her scooter sat in the garage, covered in dust. Her stuffed animals were passed down to Lila. The wooden playground in the back yard stood empty. She kept her skateboard with neon yellow wheels, because riding it is still cool to her friends.

On the morning of her 14th birthday, Katherine wakes up to an alarm ringing on her phone. It’s 6:30 a.m. She rolls over and shuts it off in the dark. Her grandparents, here to celebrate the end of her first year of teenagehood, are sleeping in the guest room down the hall. She can hear the dogs shuffling across the hardwood downstairs, waiting to be fed. Propping herself up on her peace-sign-covered pillow, she opens Instagram. Later, Lila will give her a Starbucks gift card. Her dad will bring doughnuts to her class. Her grandparents will take her to the Melting Pot for dinner. But first, her friends will decide whether to post pictures of Katherine for her birthday. Whether they like her enough to put a picture of her on their page. Those pictures, if they come, will get likes and maybe tbhs. They should be posted in the morning, any minute now. She scrolls past a friend posing in a bikini on the beach. Then a picture posted by Kendall Jenner. A selfie with coffee. A basketball Vine. A selfie with a girl’s tongue out. She scrolls, she waits. For that little notification box to appear.

For most of recorded history, people married for logical sorts of reasons:

And from such reasonable marriages, there flowed loneliness, infidelity, abuse, hardness of heart and screams heard through the nursery doors

The marriage of reason was not, in hindsight, reasonable at all; it was often expedient, narrow-minded, snobbish and exploitative. That is why what has replaced it — the marriage of feeling — has largely been spared the need to account for itself

Finally, we marry to make a nice feeling permanent. We imagine that marriage will help us to bottle the joy we felt when the thought of proposing first came to us: Perhaps we were in Venice, on the lagoon, in a motorboat

But though we believe ourselves to be seeking happiness in marriage, it isn’t that simple. What we really seek is familiarity

We are looking to recreate, within our adult relationships, the feelings we knew so well in childhood. The love most of us will have tasted early on was often confused with other, more destructive dynamics: feelings of wanting to help an adult who was out of control, of being deprived of a parent’s warmth or scared of his anger, of not feeling secure enough to communicate our wishes.

How logical, then, that we should as grown-ups find ourselves rejecting certain candidates for marriage not because they are wrong but because they are too right — too balanced, mature, understanding and reliable — given that in our hearts, such rightness feels foreign. We marry the wrong people because we don’t associate being loved with feeling happy.

We make mistakes, too, because we are so lonely. No one can be in an optimal frame of mind to choose a partner when remaining single feels unbearable. We have to be wholly at peace with the prospect of many years of solitude in order to be appropriately picky

What matters in the marriage of feeling is that two people are drawn to each other by an overwhelming instinct and know in their hearts that it is right

marriage tends decisively to move us onto another, very different and more administrative plane, which perhaps unfolds in a suburban house, with a long commute and maddening children who kill the passion from which they emerged. The only ingredient in common is the partner. And that might have been the wrong ingredient to bottle.

The good news is that it doesn’t matter if we find we have married the wrong person.

We mustn’t abandon him or her, only the founding Romantic idea upon which the Western understanding of marriage has been based the last 250 years: that a perfect being exists who can meet all our needs and satisfy our every yearning.

WE need to swap the Romantic view for a tragic (and at points comedic) awareness that every human will frustrate, anger, annoy, madden and disappoint us — and we will (without any malice) do the same to them.

But none of this is unusual or grounds for divorce. Choosing whom to commit ourselves to is merely a case of identifying which particular variety of suffering we would most like to sacrifice ourselves for.

pessimism relieves the excessive imaginative pressure that our romantic culture places upon marriage. The failure of one particular partner to save us from our grief and melancholy is not an argument against that person and no sign that a union deserves to fail or be upgraded.

The person who is best suited to us is not the person who shares our every taste (he or she doesn’t exist), but the person who can negotiate differences in taste intelligently — the person who is good at disagreement.

Rather than some notional idea of perfect complementarity, it is the capacity to tolerate differences with generosity that is the true marker of the “not overly wrong” person

We should learn to accommodate ourselves to “wrongness,” striving always to adopt a more forgiving, humorous and kindly perspective on its multiple examples in ourselves and in our partners.

The study analyzed friendship ties among 84 subjects (ages 23 to 38) in a business management class by asking them to rank one another on a five-point continuum of closeness from “I don’t know this person” to “One of my best friends.” The feelings were mutual 53 percent of the time while the expectation of reciprocity was pegged at 94 percent. This is consistent with data from several other friendship studies conducted over the past decade, encompassing more than 92,000 subjects, in which the reciprocity rates ranged from 34 percent to 53 percent.

“Friendship is difficult to describe,” said Alexander Nehamas, a professor of philosophy at Princeton, who in his latest book, “On Friendship,” spends almost 300 pages trying to do just that. “It’s easier to say what friendship is not and, foremost, it is not instrumental.”

It is not a means to obtain higher status, wangle an invitation to someone’s vacation home or simply escape your own boredom. Rather, Mr. Nehamas said, friendship is more like beauty or art, which kindles something deep within us and is “appreciated for its own sake.

“Treating friends like investments or commodities is anathema to the whole idea of friendship,” said Ronald Sharp, a professor of English at Vassar College, who teaches a course on the literature of friendship. “It’s not about what someone can do for you, it’s who and what the two of you become in each other’s presence.”

Some blame human beings’ basic optimism, if not egocentrism, for the disconnect between perceived and actual friendships. Others point to a misunderstanding of the very notion of friendship in an age when “friend” is used as a verb, and social inclusion and exclusion are as easy as a swipe or a tap on a smartphone screen.

By his definition, friends are people you take the time to understand and allow to understand you.

Because time is limited, so, too, is the number of friends you can have, according to the work of the British evolutionary psychologist Robin I.M. Dunbar. He describes layers of friendship, where the topmost layer consists of only one or two people, say a spouse and best friend with whom you are most intimate and interact daily. The next layer can accommodate at most four people for whom you have great affinity, affection and concern and who require weekly attention to maintain. Out from there, the tiers contain more casual friends with whom you invest less time and tend to have a less profound and more tenuous connection. Without consistent contact, they easily fall into the realm of acquaintance. You may be friendly with them but they aren’t friends.

“There is a limited amount of time and emotional capital we can distribute, so we only have five slots for the most intense type of relationship,” Mr. Dunbar said. “People may say they have more than five but you can be pretty sure they are not high-quality friendships.

Such boasting implies they have soul mates to spare in a culture where we are taught that leaning on someone is a sign of weakness and power is not letting others affect you. But friendship requires the vulnerability of caring as well as revealing things about yourself that don’t match the polished image in your Facebook profile or Instagram feed, said Mr. Nehamas at Princeton. Trusting that your bond will continue, and might even be strengthened, despite your shortcomings and inevitable misfortunes, he said, is a risk many aren’t willing to take.

According to medical experts, playing it safe by engaging in shallow, unfulfilling or nonreciprocal relationships has physical repercussions. Not only do the resulting feelings of loneliness and isolation increase the risk of death as much as smoking, alcoholism and obesity; you may also lose tone, or function, in the so-called smart vagus nerve, which brain researchers think allows us to be in intimate, supportive and reciprocal relationships in the first place.

In the presence of a true friend, Dr. Banks said, the smart or modulating aspect of the vagus nerve is what makes us feel at ease rather than on guard as when we are with a stranger or someone judgmental. It’s what enables us to feel O.K. about exposing the soft underbelly of our psyche and helps us stay engaged and present in times of conflict. Lacking authentic friendships, the smart vagus nerve is not exercised. It loses tone and one’s anxiety remains high, making abiding, deep connections difficult.

How do we reconcile our enjoyment of social media even as we understand that the corporations who control them aren’t always acting in our best interests?

hat was because the underlying economic conditions hadn’t been changed or “disrupted,” to use a favorite Silicon Valley phrase. Google has to serve its shareholders, just like NBCUniversal does. As a result, many of the unappealing aspects of the legacy-media model have simply carried over into a digital age — namely, commercialism, consolidation, and centralization. In fact, the new system is even more dependent on advertising dollars than the one that preceded it, and digital advertising is far more invasive and ubiquitous

the popular narrative — new communications technologies would topple the establishment and empower regular people — didn’t accurately capture reality. Something more complex and predictable was happening. The old-media dinosaurs weren’t dying out, but were adapting to the online environment; meanwhile the new tech titans were coming increasingly to resemble their predecessors

I use lots of products that are created by companies whose business practices I object to and that don’t act in my best interests, or the best interests of workers or the environment — we all do, since that’s part of living under capitalism. That said, I refuse to invest so much in any platform that I can’t quit without remorse

these services aren’t free even if we don’t pay money for them; we pay with our personal data, with our privacy. This feeds into the larger surveillance debate, since government snooping piggybacks on corporate data collection. As I argue in the book, there are also negative cultural consequences (e.g., when advertisers are paying the tab we get more of the kind of culture marketers like to associate themselves with and less of the stuff they don’t) and worrying social costs. For example, the White House and the Federal Trade Commission have both recently warned that the era of “big data” opens new avenues of discrimination and may erode hard-won consumer protections.

I’m resistant to the tendency to place this responsibility solely on the shoulders of users. Gadgets and platforms are designed to be addictive, with every element from color schemes to headlines carefully tested to maximize clickability and engagement. The recent news that Facebook tweaked its algorithms for a week in 2012, showing hundreds of thousands of users only “happy” or “sad” posts in order to study emotional contagion — in other words, to manipulate people’s mental states — is further evidence that these platforms are not neutral. In the end, Facebook wants us to feel the emotion of wanting to visit Facebook frequently

social inequalities that exist in the real world remain meaningful online. What are the particular dangers of discrimination on the Internet?

That it’s invisible or at least harder to track and prove. We haven’t figured out how to deal with the unique ways prejudice plays out over digital channels, and that’s partly because some folks can’t accept the fact that discrimination persists online. (After all, there is no sign on the door that reads Minorities Not Allowed.)

just because the Internet is open doesn’t mean it’s equal; offline hierarchies carry over to the online world and are even amplified there. For the past year or so, there has been a lively discussion taking place about the disproportionate and often outrageous sexual harassment women face simply for entering virtual space and asserting themselves there — research verifies that female Internet users are dramatically more likely to be threatened or stalked than their male counterparts — and yet there is very little agreement about what, if anything, can be done to address the problem.

What steps can we take to encourage better representation of independent and non-commercial media? We need to fund it, first and foremost. As individuals this means paying for the stuff we believe in and want to see thrive. But I don’t think enlightened consumption can get us where we need to go on its own. I’m skeptical of the idea that we can shop our way to a better world. The dominance of commercial media is a social and political problem that demands a collective solution, so I make an argument for state funding and propose a reconceptualization of public media. More generally, I’m struck by the fact that we use these civic-minded metaphors, calling Google Books a “library” or Twitter a “town square” — or even calling social media “social” — but real public options are off the table, at least in the United States. We hand the digital commons over to private corporations at our peril.

6. You advocate for greater government regulation of the Internet. Why is this important?

I’m for regulating specific things, like Internet access, which is what the fight for net neutrality is ultimately about. We also need stronger privacy protections and restrictions on data gathering, retention, and use, which won’t happen without a fight.

I challenge the techno-libertarian insistence that the government has no productive role to play and that it needs to keep its hands off the Internet for fear that it will be “broken.” The Internet and personal computing as we know them wouldn’t exist without state investment and innovation, so let’s be real.

there’s a pervasive and ill-advised faith that technology will promote competition if left to its own devices (“competition is a click away,” tech executives like to say), but that’s not true for a variety of reasons. The paradox of our current media landscape is this: our devices and consumption patterns are ever more personalized, yet we’re simultaneously connected to this immense, opaque, centralized infrastructure. We’re all dependent on a handful of firms that are effectively monopolies — from Time Warner and Comcast on up to Google and Facebook — and we’re seeing increased vertical integration, with companies acting as both distributors and creators of content. Amazon aspires to be the bookstore, the bookshelf, and the book. Google isn’t just a search engine, a popular browser, and an operating system; it also invests in original content

So it’s not that the Internet needs to be regulated but that these big tech corporations need to be subject to governmental oversight. After all, they are reaching farther and farther into our intimate lives. They’re watching us. Someone should be watching them.

In March, Pew asked people whether life was better for people like them 50 years ago — and a majority of Republicans answered yes. Trump supporters were the most emphatic, with 75 percent saying things were better in the mid-1960s.Democrats, though, were less enthusiastic about the past. Forty-eight percent said life was better now than it was 50 years ago, while 17 percent of Democrats said it was the same, and only 28 percent said it was worse.

In the Morning Consult survey, 44 percent of people over all said America’s greatest years were ahead of it, while 36 percent said those years had already passed. But in an election when America’s past greatness has played such a starring role, we wanted to see more details about just how voters saw the past and the future.

So, when was the greatest year?Over all, 2000 was the most popular choice, a preference that cut across political party, candidate preference, gender and age. The year’s popularity may partly reflect people’s fondness for round numbers. But many voters explained their choice by referring to a greater sense of security. The Sept. 11 attacks occurred the following year. (An election year also has something for all partisans to grab onto. Bill Clinton was president that year, but George W. Bush won the election to replace him.)

Some people, of course, reached farther back into history. The year the Declaration of Independence was signed, 1776, got a few votes. One person chose 1789, the year the Constitution took effect. One person chose 1800. One chose 1860, the year Southern states began to secede from the Union. But most answers were of a more recent vintage.

partisan patterns in views of America’s greatness. Republicans, over all, recall the late 1950s and the mid-1980s most fondly. Sample explanations: “Reagan.” “Economy was booming.” “No wars!” “Life was simpler.” “Strong family values.” The distribution of Trump supporters’ greatest years is somewhat similar to the Republican trend, but more widely dispersed over the last 70 years.

Democrats seem to think America’s greatest days were more recent; they were more likely to pick a year in the 1990s, or since 2000. After 2000, their second-most-popular answer was 2016. Sample explanations: “We’re getting better.” “Improving social justice.” “Technology.” Even 2008, a year of financial collapse, was pretty popular, perhaps because President Obama was also elected that year.

the lesson in Virginia, as the Washington Post reporter Paul Farhi wrote at the time, was that nothing exceeds the value of shoe-leather reporting, given that politics is an essentially human endeavor and therefore can defy prediction and reason.

Yet when Mr. Trump showed up on the scene, it was as if that had never happened.

It was another thing to declare, as The Huffington Post did, that coverage of his campaign could be relegated to the entertainment section (and to add a disclaimer to articles about him) and still another to give Mr. Trump a “2 percent” chance at the nomination despite strong polls in his favor, as FiveThirtyEight did six months before the first votes were cast.

Predictions that far out can be viewed as being all in good fun. But in Mr. Trump’s case, they also arguably sapped the journalistic will to scour his record as aggressively as those of his supposedly more serious rivals. In other words, predictions can have consequences.

The problems weren’t at all only due to the reliance on data. Don’t forget those moments that were supposed to have augured Mr. Trump’s collapse: the certainty that once the race narrowed to two or three candidates, Mr. Trump would be through, and what at one point became the likelihood of a contested convention.

That’s all the more reason in the coming months to be as sharply focused on the data we don’t have as we are on the data we do have (and maybe watching out for making any big predictions about the fall based on the polling of today). But a good place to start would be to get a good night’s sleep, and then talk to some voters.

In the last four years, Stanford has increased the number of senior faculty by 25 percent, and 11 scholars with millions in cumulative salary have either been recruited from other top programs or resisted poaching attempts by those programs.

The specialties of the new recruits vary, but they are all examples of how the momentum in economics has shifted away from theoretical modeling and toward “empirical microeconomics,” the analysis of how things work in the real world, often arranging complex experiments or exploiting large sets of data. That kind of work requires lots of research assistants, work across disciplines including fields like sociology and computer science, and the use of advanced computational techniques unavailable a generation ago.

the scholars who have newly signed on with Stanford described a university particularly well suited to research in that vein, with a combination of lab space, strong budgets for research support and proximity to engineering talent.

The Chicago School, under the intellectual imprint of Milton Friedman, was a leader in neoclassical thought that emphasizes the efficiency of markets and the risks of government intervention. M.I.T.’s economics department has a long record of economic thought in the Keynesian tradition, and it produced several of the top policy makers who have guided the world economy through the tumultuous last several years.

“There isn’t a Stanford school of thought,” said B. Douglas Bernheim, chairman of the university’s economics department. “This isn’t a doctrinaire place. Generally doctrine involves simplification, and increasingly we recognize that these social issues we’re trying to figure out are phenomenally complicated. The consensus at Stanford has focused around the idea that you have to be open to a lot of approaches and ways of thinking about things, and to be rigorous, thorough and careful in bringing the highest standard of craft to bear on your research.”

“My sense is this is a good development for economics,” Mr. Chetty said. “I think Stanford is going to be another great department at the level of Harvard and M.I.T. doing this type of work, which is an example of economics becoming a deeper field. It’s a great thing for all the universities — I don’t think it’s a zero-sum game.”
