After years of too little attention, the subject of head injuries in sports, and how to prevent them, is now what Twitter would call a "trending topic."
First came the turnaround in attitudes toward NFL player head injuries, and the helmet-to-helmet tackles and hits that increase the risk of those injuries. Then came the discussion about skier Lindsey Vonn's continued participation in the World Cup last week, despite clear indications and admissions on her part that she was still skiing behind the course and "in a fog" after suffering a concussion in a training accident. And now, there's the U.S. lacrosse league debating whether or not the girls -- who now only have to wear protective eye gear—should be required to wear helmets as well.
Girls' lacrosse has dramatically different rules than the boys' game: body checks are illegal, as are certain stick checks, and there is a regulated safety zone around each girl's head. Nevertheless, research quoted in a New York Timesarticle today concluded that when it comes to concussions, lacrosse ranks third in female sports (behind basketball and soccer). In addition, despite the less-aggressive nature and rules of the girls' game, girls' lacrosse has an in-game concussion rate only 15 percent lower than the boys.
So if concussions are an issue in girls' lacrosse, the argument goes, we should require girls to wear more protective headgear. After all, the boys' helmets, intended to reduce skull fracture and intracranial bleeding, are thought to reduce the number of concussions, as well.
But does the addition of extra safety gear actually reduce the risk of the injuries it is designed to prevent? Well, yes ... and no. Which is what fuels the debate on the issue.
Taken by itself, it's easy enough to prove that wearing a helmet, like wearing a seat belt, decreases the chance or severity of injury in an impact. But humans are far more complex creatures than crash test dummies. And so the true impact of safety equipment becomes far more complex, as well.
In his 1995 book Risk, British researcher John Adams spelled out several reasons why safety equipment does not always increase safety the way its designers or legislators think it will. The first is a phenomenon called "risk compensation," in which humans respond to additional safety equipment by taking greater risks than they did when they felt less protected. For example, Adams said, while seat belts unquestionably gave a person better protection if they were in a collision, the chances of being in a collision went up in places with seat belt laws, because seat-belted drivers took more risks in how they drove.
For all the time and discussion space we devote to the goal of eliminating accidents or injuries, Adams suggests that people have "risk thermostats," and that we all adjust our behavior to maintain the level of risk in our lives that we find acceptable. We all compensate for the extra margin provided by safety equipment to some degree, and some of us will push the new boundaries further than others. All of which means that safety equipment often doesn't make as much of a difference as its proponents believe it will.
Indeed, there are many who argue that mandatory helmets, and increasingly strong helmets, have actually exacerbated the problem of head injury in sports ranging from boys' lacrosse and ice hockey to professional football. So perhaps helmets for female lacrosse players really are a bad idea, as U.S. Lacrosse (the sport's governing body) argues.
So what's the solution? In many cases, improving safety has had more to do with changing a group's culture and attitudes about high-risk activities than it does any specific technological advance -- especially in individual sports or hobbies.
A prominent example is the Cirrus Design company (a company profiled by James Fallows in his Atlanticarticle and subsequent bookFree Flight). In an effort to build a safer aircraft, Cirrus included a full-airplane parachute and vastly improved "glass" cockpit displays in its Cirrus airplane. But when the airplane was first introduced, it actually had a significantly higher-than-average fatality rate, because pilots -- comforted by the extra technology and safety systems -- "compensated" by pushing the aircraft into weather they wouldn't otherwise have undertaken. In the end, the company was able to bring its accident rates down by requiring additional training and working to change the culture of its buyers—at least to some degree.
The field of SCUBA diving also vastly reduced its accident rate over several decades by changing its group attitudes toward risk. Once upon a time, diving was a macho sport where the toughest regularly pushed the limits. Today, attitudes about pushing the limits have changed. Dive without a buddy, push your depth or time limits, and a diver today is likely to be seen as stupid, not brave.
Notably, the NFL is now taking a similar approach toward head injuries. Instead of simply improving the cushioning in players' helmets, the NFL is trying to change the league's culture, rules and consequences related to hits to the head, or tackles "leading" with a player's helmet. How well that works remains to be seen, of course. But the popular image and standard for what's "admirable" and "acceptable" in tackling technique has already changed dramatically, even in the breathtakingly short span of a single season.
But girls' lacrosse already has a restrictive set of rules regarding contact. And most of the concussions its players suffer come from accidental contact and falls, not intentionally aggressive maneuvering. So is it a different case? Could helmets actually make it safer?
"I think helmets encourage you to push the limits of whatever the rules are," one high school athlete responded, when I asked the question. "If you're only allowed one kind of hit, you'll hit as hard as you can in that one way. But given that girls' lacrosse has so many rules restricting contact, [helmets] might actually help."
Of course, given the complexities of how humans assess and respond to risk, and the fact that lacrosse players are unlikely to be timid or risk-adverse by nature, it's also a fair bet that whatever safety margin helmets provide would—at best—be narrowed by some amount by compensating behavior on the part of the players. Which means at some point in the future, U.S. Lacrosse, like Cirrus and the NFL, may find itself compensating for that compensation through more complex solutions than the seemingly-simple answer of a helmet.
When President Obama left, I stayed on at the National Security Council in order to serve my country. I lasted eight days.
In 2011, I was hired, straight out of college, to work at the White House and eventually the National Security Council. My job there was to promote and protect the best of what my country stands for. I am a hijab-wearing Muslim woman––I was the only hijabi in the West Wing––and the Obama administration always made me feel welcome and included.
Like most of my fellow American Muslims, I spent much of 2016 watching with consternation as Donald Trump vilified our community. Despite this––or because of it––I thought I should try to stay on the NSC staff during the Trump Administration, in order to give the new president and his aides a more nuanced view of Islam, and of America's Muslim citizens.
Meet the protesters who tricked conference attendees into waving Russian flags.
Two men made trouble—and stirred up a social-media frenzy—on the third day of the Conservative Political Action Conference by conducting a literal false-flag operation.
Jason Charter, 22, and Ryan Clayton, 36, passed out roughly 1,000 red, white, and blue flags, each bearing a gold-emblazoned “TRUMP” in the center, to an auditorium full of attendees waiting for President Trump to address the conference. Audience members waved the pennants—and took pictures with them—until CPAC staffers realized the trick: They were Russian flags.
The stunt made waves on social media, as journalists covering CPAC noticed the scramble to confiscate the insignia.
Long after research contradicts common medical practices, patients continue to demand them and physicians continue to deliver. The result is an epidemic of unnecessary and unhelpful treatments.
First, listen to the story with the happy ending: At 61, the executive was in excellent health. His blood pressure was a bit high, but everything else looked good, and he exercised regularly. Then he had a scare. He went for a brisk post-lunch walk on a cool winter day, and his chest began to hurt. Back inside his office, he sat down, and the pain disappeared as quickly as it had come.
That night, he thought more about it: middle-aged man, high blood pressure, stressful job, chest discomfort. The next day, he went to a local emergency department. Doctors determined that the man had not suffered a heart attack and that the electrical activity of his heart was completely normal. All signs suggested that the executive had stable angina—chest pain that occurs when the heart muscle is getting less blood-borne oxygen than it needs, often because an artery is partially blocked.
“No… it’s a magic potty,” my daughter used to lament, age 3 or so, before refusing to use a public restroom stall with an automatic-flush toilet. As a small person, she was accustomed to the infrared sensor detecting erratic motion at the top of her head and violently flushing beneath her. Better, in her mind, just to delay relief than to subject herself to the magic potty’s dark dealings.
It’s hardly just a problem for small people. What adult hasn’t suffered the pneumatic public toilet’s whirlwind underneath them? Or again when attempting to exit the stall? So many ordinary objects and experiences have become technologized—made dependent on computers, sensors, and other apparatuses meant to improve them—that they have also ceased to work in their usual manner. It’s common to think of such defects as matters of bad design. That’s true, in part. But technology is also more precarious than it once was. Unstable, and unpredictable. At least from the perspective of human users. From the vantage point of technology, if it can be said to have a vantage point, it's evolving separately from human use.
The preconditions are present in the U.S. today. Here’s the playbook Donald Trump could use to set the country down a path toward illiberalism.
It’s 2021, and President Donald Trump will shortly be sworn in for his second term. The 45th president has visibly aged over the past four years. He rests heavily on his daughter Ivanka’s arm during his infrequent public appearances.
Fortunately for him, he did not need to campaign hard for reelection. His has been a popular presidency: Big tax cuts, big spending, and big deficits have worked their familiar expansive magic. Wages have grown strongly in the Trump years, especially for men without a college degree, even if rising inflation is beginning to bite into the gains. The president’s supporters credit his restrictive immigration policies and his TrumpWorks infrastructure program.

New research suggests it’s how parents talk to their infants, not just how often, that makes a difference for language development.
A few weeks ago, I was eating lunch with my family at a pancake house when a small blond head popped over the top of the booth next to ours.
Somewhere in the ballpark of a year old, the boy said something unintelligible—maybe baby babbling, maybe real words muffled by pancake—and gave a high-pitched giggle. He waved a tiny-syrup smeared arm in my direction.
“He’s such a flirt,” his mother said apologetically.
“He is,” cooed my own mother, who can befriend anything that will stand still long enough. “Hiiiiii.” She kicked me under the table.
“Oh—hi,” I said. I waved back. But men are fickle creatures, and our neighbor only frowned, turned around and sat back down to his food.
Millions of Americans are worried that Donald Trump is an ominous figure. Investors have another theory: maybe not.
Donald Trump so permeates the collective consciousness of the country that it is hard to imagine now living in a world without him. But there is one place where the president seems to be relatively invisible—the U.S. stock market.
The Dow, S&P, and Nasdaq have set record highs in the months after Trump’s election. On Thursday, the Dow has its tenth consecutive record closing in a row, at 20,810. This is happening, despite the fact that investors seemed terrified of a Trump presidency in the general election campaign. Trump came into office promising to antagonize America’s allies and economic partners while crushing the international establishment. None of this is particularly favorable to multinational corporations. Even worse, Trump’s first few weeks in office were a maelstrom of hasty lawmaking and furious backtracking, exactly the sort of behavior one might consider a threat to the all-important “certainty” that markets ostensibly crave. What’s more, mainstream economists are nearly united in their certainty that Trump’s core policies, like scrapping free trade agreements while severely limiting immigration, would be bad for the country.
Neil Gaiman’s remarkable new book has triggered a debate about who, exactly, owns pagan tales.
Myths are funny. Unlike histories, they are symbolic narratives; they deal with spiritual rather than fact-based truths. They serve as foundations for beliefs, illustrating how things came to be and who was involved, but they’re often sketchy about when or why. There’s a brief scene from Neil Gaiman’s new book Norse Mythology that does a remarkable job of capturing just this: the wonderfully nebulous sense of being in illo tempore—the hazy “at that time” of the mythic past. It begins, as many creation myths do, with “an empty place waiting to be filled with life,” but in this instance some life already exists. There’s Ymir, whose enormous body produces all giants and, eventually, the earth, skies, and seas. There’s Audhumla, the celestial cow, who licks the first gods out of blocks of ice. And there are three brothers—the gods Ve, Vili, and Odin—who must devise a way out of this timeless nowhere:
Students can learn the basics with a set of knitting needles.
The Finns are pretty bemused by Americans’ preoccupation with whether to put iPads in every classroom. If a tablet would enhance learning, great. If it wouldn’t, skip it. Move on. The whole thing is a little tilting-at-windmills, anyway.
That was the gist of the conversation one recent morning at the Finnish Embassy in Washington, D.C., where diplomats and experts gathered to celebrate the country’s education accomplishments as Finland turns 100. And Americans could stand to take notes. (Yes, from Finland—again.)
Coding and programming are now part of the curriculum in the Scandinavian country, and they’re subjects kids tackle from a young age. But unlike in some parts of the United States where learning to code is an isolated skill, Finnish children are taught to think of coding and programming more as tools to be explored and utilized across multiple subjects.
His death has punctured the myth of the Kims' holy bloodline.
As the first son of Kim Jong Il, the late leader of the Democratic People’s Republic of Korea, Kim Jong Nam always posed a threat to Kim Jong Un, his half brother and North Korea’s current leader. Before falling out of favor with his father and going into exile soon after, paving the way for Kim Jong Un’s ascent, Kim Jong Nam was the heir apparent. With the execution in 2013 of Jang Sung Tak, the second in command and the eldest son’s staunchest supporter, Kim Jong Nam was unprotected, with little hope of ever returning home.
On February 13, Kim Jong Nam was murdered in Kuala Lumpur airport by two hired killers. The fascination surrounding the killing has centered on its sensational circumstances: that one ofthe killers smeared a poisonous toxin, reportedly VX gas, across Kim’s face; that one of them wore a T-shirt with the acronym “LOL” printed across the front; that the other reportedly mistookthe hit for a comedy stunt. Malaysian police have detained five people allegedly connected to the killing, and remain on the hunt for others—including several North Koreans—linked to it.
