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.
Einstein’s gravitational waves rest on a genuinely radical idea.
After decades of anticipation, we have directly detected gravitational waves—ripples in spacetime traveling at the speed of light through the universe. Scientists at LIGO (the Laser Interferometic Gravitational-wave Observatory) have announced that they have measured waves coming from the inspiral of two massive black holes, providing a spectacular confirmation of Albert Einstein’s general theory of relativity, whose hundredth anniversary was celebrated just last year.
Finding gravitational waves indicates that Einstein was (once again) right, and opens a new window onto energetic events occurring around the universe. But there’s a deeper lesson, as well: a reminder of the central importance of locality, an idea that underlies much of modern physics.
Most people know how to help someone with a cut or a scrape. But what about a panic attack?
Here’s a thought experiment: You’re walking down the street with a friend when your companion falls and gashes her leg on the concrete. It’s bleeding; she’s in pain. It’s clear she’s going to need stitches. What do you do?
This one isn’t exactly a head-scratcher. You'd probably attempt to offer some sort of first-aid assistance until the bleeding stopped, or until she could get to medical help. Maybe you happen to have a Band-Aid on you, or a tissue to help her clean the wound, or a water bottle she can use to rinse it off. Maybe you pick her up and help her hobble towards transportation, or take her where she needs to go.
Here’s a harder one: What if, instead of an injured leg, that same friend has a panic attack?
Today’s empires are born on the web, and exert tremendous power in the material world.
Mark Zuckerberg hasn’t had the best week.
First, Facebook’s Free Basics platform was effectively banned in India. Then, a high-profile member of Facebook’s board of directors, the venture capitalist Marc Andreessen, sounded off about the decision to his nearly half-a-million Twitter followers with a stunning comment.
“Anti-colonialism has been economically catastrophic for the Indian people for decades,” Andreessen wrote. “Why stop now?”
After that, the Internet went nuts.
Andreessen deleted his tweet, apologized, and underscored that he is “100 percent opposed to colonialism” and “100 percent in favor of independence and freedom.” Zuckerberg, Facebook’s CEO, followed up with his own Facebook post to say Andreessen’s comment was “deeply upsetting” to him, and not representative of the way he thinks “at all.”
Ben Stiller’s follow-up to his own comedy classic is a downright bummer, no matter how many celebrity cameos it tries to cram in.
You don’t need to go to the theater to get the full experience of Zoolander 2. Simply get your hands on a copy of the original, watch it, and then yell a bunch of unfunny topical lines every time somebody tells a joke. That’s how it feels to watch Ben Stiller’s sequel to his 2001 spoof of the fashion industry: Zoolander 2 takes pains to reference every successful gag you remember from the original, and then embellish them in painful—often offensive, almost always outdated—fashion. It’s a film that has no real reason to exist, and it spends its entire running time reaffirming that fact.
The original Zoolander, to be fair, had no business being as funny as it was—it made fun of an industry that already seems to exist in a constant state of self-parody, and much of its humor relied on simple malapropisms and sight gags. But it was hilarious anyway as a candid snapshot of the fizzling-out of ’90s culture. Like almost any zeitgeist comedy, it belonged to a particular moment—and boy, should it have stayed there. With Zoolander 2, Stiller (who directed, co-wrote, and stars) tries to recapture the magic of 2001 by referencing its past glories with increasing desperation, perhaps to avoid the fact that he has nothing new to say about the fashion industry or celebrity culture 15 years laters.
The bureau successfully played the long game in both cases.
The story of law enforcement in the Oregon standoff is one of patience.
On the most obvious level, that was reflected in the 41 days that armed militia members occupied the Malheur National Wildlife Refuge near Burns. It took 25 days before the FBI and state police moved to arrest several leaders of the occupation and to barricade the refuge. It took another 15 days before the last of the final occupiers walked out, Thursday morning Oregon time.
Each of those cases involved patience as well: Officers massed on Highway 395 didn’t shoot LaVoy Finicum when he tried to ram past a barricade, nearly striking an FBI agent, though when he reached for a gun in his pocket they finally fired. Meanwhile, despite increasingly hysterical behavior from David Fry, the final occupier, officers waited him out until he emerged peacefully.
By mining electronic medical records, scientists show the lasting legacy of prehistoric sex on modern humans’ health.
Modern humans originated in Africa, and started spreading around the world about 60,000 years ago. As they entered Asia and Europe, they encountered other groups of ancient humans that had already settled in these regions, such as Neanderthals. And sometimes, when these groups met, they had sex.
We know about these prehistoric liaisons because they left permanent marks on our genome. Even though Neanderthals are now extinct, every living person outside of Africa can trace between 1 and 5 percent of our DNA back to them. (I am 2.6 percent Neanderthal, if you were wondering, which pales in comparison to my colleague James Fallows at 5 percent.)
This lasting legacy was revealed in 2010 when the complete Neanderthal genome was published. Since then, researchers have been trying to figure out what, if anything, the Neanderthal sequences are doing in our own genome. Are they just passive hitchhikers, or did they bestow important adaptations on early humans? And are they affecting the health of modern ones?
Jim Gilmore joins Chris Christie and Carly Fiorina, and leaves the race after a poor showing in New Hampshire.
Jim Gilmore’s candidacy this year was improbable—but even more improbable was the minor cult of personality that developed around it.
The former Virginia governor never had a chance. Not, like, in the sense of Lindsey Graham, a candidate with national standing but no path to the presidency. More in the George Pataki sense: a guy who had no real business in race, but was running anyway. Except that Gilmore made Pataki look like a juggernaut. Also, Pataki saw the writing on the wall and had the sense to drop out in late December. Gilmore soldiered on, and ended up as the last of the truly longshots to leave.
The result was that Gilmore turned into a sort of folk hero. Not for voters, mind you—he managed only 12 votes in Iowa and 125 in New Hampshire, and his campaign was funded largely by loans from himself. Because of his low support in the polls, Gilmore only made the cut for the very first kid’s-table debate in August, and then again for the undercard in late January. Other than that, he was shut out completely.
How teachers and parents can identify and cultivate children who think creatively and unconventionally
In his new book, Originals: How Non-Conformists Move the World, the writer, Wharton professor, and erstwhile magician Adam Grant explores the circumstances that give rise to truly original thinkers. Through stories of business “originals” such as the Bridgewater Associates founder Ray Dalio, and the Warby Parker co-founder Neil Blumenthal, he explains how unorthodox thinking can result in unprecedented success or—if shaped by groupthink or myopic vision—miserable failure.
Grant is a gifted educator himself, and, as Wharton’s top rated teacher for the past four years, knows a little something about identifying and cultivating original thinking in his students. I asked Grant about the role teachers play in educating original children, and how teachers and parents alike can protect what’s special in these original children—traits that have the potential to disrupt lesson plans today, but, if nurtured and protected, may just change the world tomorrow. Below is a lightly edited and condensed version of our conversation.
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.
When four American women were murdered during El Salvador’s dirty war, a young U.S. official and his unlikely partner risked their lives to solve the case.
On December 1, 1980, two American Catholic churchwomen—an Ursuline nun and a lay missionary—sat down to dinner with Robert White, the U.S. ambassador to El Salvador. They worked in rural areas ministering to El Salvador’s desperately impoverished peasants, and White admired their commitment and courage. The talk turned to the government’s brutal tactics for fighting the country’s left-wing guerrillas, in a dirty war waged by death squads that dumped bodies in the streets and an army that massacred civilians. The women were alarmed by the incoming Reagan administration’s plans for a closer relationship with the military-led government. Because of a curfew, the women spent the night at the ambassador’s residence. The next day, after breakfast with the ambassador’s wife, they drove to San Salvador’s international airport to pick up two colleagues who were flying back from a conference in Nicaragua. Within hours, all four women would be dead.
