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.

Before it became the New World, the Western Hemisphere was vastly more populous and sophisticated than has been thought—an altogether more salubrious place to live at the time than, say, Europe. New evidence of both the extent of the population and its agricultural advancement leads to a remarkable conjecture: the Amazon rain forest may be largely a human artifact
The plane took off in weather that was surprisingly cool for north-central Bolivia and flew east, toward the Brazilian border. In a few minutes the roads and houses disappeared, and the only evidence of human settlement was the cattle scattered over the savannah like jimmies on ice cream. Then they, too, disappeared. By that time the archaeologists had their cameras out and were clicking away in delight.
Below us was the Beni, a Bolivian province about the size of Illinois and Indiana put together, and nearly as flat. For almost half the year rain and snowmelt from the mountains to the south and west cover the land with an irregular, slowly moving skin of water that eventually ends up in the province's northern rivers, which are sub-subtributaries of the Amazon. The rest of the year the water dries up and the bright-green vastness turns into something that resembles a desert. This peculiar, remote, watery plain was what had drawn the researchers' attention, and not just because it was one of the few places on earth inhabited by people who might never have seen Westerners with cameras.
Paul faced danger, Ani and Ray faced each other, and Frank faced some career decisions.
This is what happens when you devote two-thirds of a season to scene after scene after scene of Frank and Jordan’s Baby Problems, and Frank Shaking Guys Down, and Look How Fucked Up Ray and Ani Are, and Melancholy Singer in the Dive Bar Yet Again—and then you suddenly realize that with only a couple episodes left you haven’t offered even a rudimentary outline of the central plot.
The Islamic State is no mere collection of psychopaths. It is a religious group with carefully considered beliefs, among them that it is a key agent of the coming apocalypse. Here’s what that means for its strategy—and for how to stop it.
What is the Islamic State?
Where did it come from, and what are its intentions? The simplicity of these questions can be deceiving, and few Western leaders seem to know the answers. In December, The New York Times published confidential comments by Major General Michael K. Nagata, the Special Operations commander for the United States in the Middle East, admitting that he had hardly begun figuring out the Islamic State’s appeal. “We have not defeated the idea,” he said. “We do not even understand the idea.” In the past year, President Obama has referred to the Islamic State, variously, as “not Islamic” and as al-Qaeda’s “jayvee team,” statements that reflected confusion about the group, and may have contributed to significant strategic errors.
Writing used to be a solitary profession. How did it become so interminably social?
Whether we’re behind the podium or awaiting our turn, numbing our bottoms on the chill of metal foldout chairs or trying to work some life into our terror-stricken tongues, we introverts feel the pain of the public performance. This is because there are requirements to being a writer. Other than being a writer, I mean. Firstly, there’s the need to become part of the writing “community”, which compels every writer who craves self respect and success to attend community events, help to organize them, buzz over them, and—despite blitzed nerves and staggering bowels—present and perform at them. We get through it. We bully ourselves into it. We dose ourselves with beta blockers. We drink. We become our own worst enemies for a night of validation and participation.
Even when they’re adopted, the children of the wealthy grow up to be just as well-off as their parents.
Lately, it seems that every new study about social mobility further corrodes the story Americans tell themselves about meritocracy; each one provides more evidence that comfortable lives are reserved for the winners of what sociologists call the birth lottery. But, recently, there have been suggestions that the birth lottery’s outcomes can be manipulated even after the fluttering ping-pong balls of inequality have been drawn.
What appears to matter—a lot—is environment, and that’s something that can be controlled. For example, one study out of Harvard found that moving poor families into better neighborhoods greatly increased the chances that children would escape poverty when they grew up.
While it’s well documentedthat the children of the wealthy tend to grow up to be wealthy, researchers are still at work on how and why that happens. Perhaps they grow up to be rich because they genetically inherit certain skills and preferences, such as a tendency to tuck away money into savings. Or perhaps it’s mostly because wealthier parents invest more in their children’s education and help them get well-paid jobs. Is it more nature, or more nurture?
What if Joe Biden is going to run for the Democratic nomination after all?
Most Democrats seem ready for Hillary Clinton—or at least appear content with her candidacy. But what about the ones who who were bidin’ for Biden? There are new signs the vice president might consider running for president after all.
Biden has given little indication he was exploring a run: There’s no super PAC, no cultivation of a network of fundraisers or grassroots organizers, few visits to early-primary states. While his boss hasn’t endorsed Clinton—and says he won’t endorse in the primary—many members of the Obama administration have gone to work for Clinton, including some close to Biden.
But Biden also hasn’t given any clear indication that he isn’t running, and a column by Maureen Dowd in Saturday’s New York Times has set off new speculation. One reason Biden didn’t get into the race was that his son Beau was dying of cancer, and the vice president was focused on being with his son. But before he died in May, Dowd reported, Beau Biden tried to get his father to promise to run. Now Joe Biden is considering the idea.
Two hundred fifty years of slavery. Ninety years of Jim Crow. Sixty years of separate but equal. Thirty-five years of racist housing policy. Until we reckon with our compounding moral debts, America will never be whole.
And if thy brother, a Hebrew man, or a Hebrew woman, be sold unto thee, and serve thee six years; then in the seventh year thou shalt let him go free from thee. And when thou sendest him out free from thee, thou shalt not let him go away empty: thou shalt furnish him liberally out of thy flock, and out of thy floor, and out of thy winepress: of that wherewith the LORD thy God hath blessed thee thou shalt give unto him. And thou shalt remember that thou wast a bondman in the land of Egypt, and the LORD thy God redeemed thee: therefore I command thee this thing today.
— Deuteronomy 15: 12–15
Besides the crime which consists in violating the law, and varying from the right rule of reason, whereby a man so far becomes degenerate, and declares himself to quit the principles of human nature, and to be a noxious creature, there is commonly injury done to some person or other, and some other man receives damage by his transgression: in which case he who hath received any damage, has, besides the right of punishment common to him with other men, a particular right to seek reparation.
Put simply: Climate change poses the threat of global catastrophe. The planet isn’t just getting hotter, it’s destabilizing. Entire ecosystems are at risk. The future of humanity is at stake.
Scientists warn that extreme weather will get worse and huge swaths of coastal cities will be submerged by ever-more-acidic oceans. All of which raises a question: If climate change continues at this pace, is anywhere going to be safe?
“Switzerland would be a good guess,” said James Hansen, the director of climate science at Columbia University’s Earth Institute. Hansen’s latest climate study warns that climate change is actually happening faster than computer models previously predicted. He and more than a dozen co-authors found that sea levels could rise at least 10 feet in the next 50 years. Slatepoints out that although the study isn’t yet peer-reviewed, Hansen is “known for being alarmist and also right.”
A new EPA rule is designed to withstand legal challenges from Republicans while convincing world leaders to follow suit.
President Obama’s plan to reduce greenhouse-gas emissions is aimed at three major constituencies. First, there’s the plan’s immediate goal: significant decreases in the emissions in the U.S. between now and 2030. Second, the rule arrives as the world gears up for global emissions talks in Paris in December, and American action is seen as necessary to convince other countries to act. And third, Obama views the fight against climate change as an essential part of his legacy, alongside the Affordable Care Act.
“We’re the first generation to feel the impact of climate change, and the last generation that can do something about it,” Obama said at a press conference at the White House on Monday, repeating a line he’s used before. The president emphasized the moral case for reducing emissions throughout the speech, invoking Pope Francis’s call for action, and scolding “cynical” critics who charged his plan would hurt minorities and the poor. “If you care about low-income minority communities, start protecting the air they breathe and stop trying to rob them of their health care.”
