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.
In the name of emotional well-being, college students are increasingly demanding protection from words and ideas they don’t like. Here’s why that’s disastrous for education—and mental health.
Something strange is happening at America’s colleges and universities. A movement is arising, undirected and driven largely by students, to scrub campuses clean of words, ideas, and subjects that might cause discomfort or give offense. Last December, Jeannie Suk wrote in an online article for The New Yorker about law students asking her fellow professors at Harvard not to teach rape law—or, in one case, even use the word violate (as in “that violates the law”) lest it cause students distress. In February, Laura Kipnis, a professor at Northwestern University, wrote an essay in The Chronicle of Higher Education describing a new campus politics of sexual paranoia—and was then subjected to a long investigation after students who were offended by the article and by a tweet she’d sent filed Title IX complaints against her. In June, a professor protecting himself with a pseudonym wrote an essay for Vox describing how gingerly he now has to teach. “I’m a Liberal Professor, and My Liberal Students Terrify Me,” the headline said. A number of popular comedians, including Chris Rock, have stopped performing on college campuses (see Caitlin Flanagan’s article in this month’s issue). Jerry Seinfeld and Bill Maher have publicly condemned the oversensitivity of college students, saying too many of them can’t take a joke.
The drug modafinil was recently found to enhance cognition in healthy people. Should you take it to get a raise?
If you could take a pill that will make you better at your job, with few or no negative consequences, would you do it?
In a meta-analysis recently published in European Neuropsychopharmacology, researchers from the University of Oxford and Harvard Medical School concluded that a drug called modafinil, which is typically used to treat sleep disorders, is a cognitive enhancer. Essentially, it can help normal people think better.
Out of all cognitive processes, modafinil was found to improve decision-making and planning the most in the 24 studies the authors reviewed. Some of the studies also showed gains in flexible thinking, combining information, or coping with novelty. The drug didn’t seem to influence creativity either way.
Four and a half years of violent conflict have destroyed entire regions of Syria. Caught in the middle of all this horror are the children of Syria, relying on parents who have lost control of their own lives and are now being forced to make difficult choices in desperate circumstances.
Four and a half years of violent conflict have destroyed entire regions of Syria. Neighborhoods have been smashed by shelling and government barrel bombs, and towns have been seized by rebels and ISIS militants, then retaken by government troops, killing hundreds of thousands and injuring even more. The United Nations now estimates that more than 4 million Syrians have become refugees, forced to flee to neighboring countries or Europe. Caught in the middle of all this horror are the children of Syria, relying on parents who have lost control of their own lives and are now being forced to make difficult choices in desperate circumstances. Though many families remain in Syria’s war zones, thousands of others are taking dangerous measures to escape, evading militias, government forces, border guards, predatory traffickers, and more, as they struggle to reach safety far from home.
But no tale of posthumous success is quite as spectacular as that of Howard Phillips Lovecraft, the “cosmic horror” writer who died in Providence, Rhode Island, in 1937 at the age of 46. The circumstances of Lovecraft’s final years were as bleak as anyone’s. He ate expired canned food and wrote to a friend, “I was never closer to the bread-line.” He never saw his stories collectively published in book form, and, before succumbing to intestinal cancer, he wrote, “I have no illusions concerning the precarious status of my tales, and do not expect to become a serious competitor of my favorite weird authors.” Among the last words the author uttered were, “Sometimes the pain is unbearable.” His obituary in the Providence Evening Bulletin was “full of errors large and small,” according to his biographer.
A new study finds an algorithmic word analysis is flawless at determining whether a person will have a psychotic episode.
Although the language of thinking is deliberate—let me think, I have to do some thinking—the actual experience of having thoughts is often passive. Ideas pop up like dandelions; thoughts occur suddenly and escape without warning. People swim in and out of pools of thought in a way that can feel, paradoxically, mindless.
Most of the time, people don’t actively track the way one thought flows into the next. But in psychiatry, much attention is paid to such intricacies of thinking. For instance, disorganized thought, evidenced by disjointed patterns in speech, is considered a hallmark characteristic of schizophrenia. Several studies of at-risk youths have found that doctors are able to guess with impressive accuracy—the best predictive models hover around 79 percent—whether a person will develop psychosis based on tracking that person’s speech patterns in interviews.
In the United States and Israel, a heated debate about whether to accept the nuclear deal with Iran continues. In the rest of the world, Iran’s reintegration is already underway.
The survival of the Iran deal seems more likely by the day; for past assessments of what that might mean for the Middle East, the United States, and beyond, please see the items grouped here.
Two weeks ago, as part of a collection of notes from readers in Israel, I quoted Samuel J. Cohen, who is originally American but has lived and worked in Israel since the 1970s, on the possibility that “Obama and Netanyahu are both right.” That is: President Obama is right that ending Iran’s pariah status will overall be good for the United States, and Prime Minister Netanyahu is right that the same change may be overall bad for Israel, even if Iran never develops a nuclear weapon. Thus the interests of the two nations genuinely diverge.
All of the downsides of being a subordinate, combined with all of the downsides of having to tell people to do things they don't want to do.
When researchers try to determine the types of workers who are most prone to depression, the focus is usually on the misery of those at the bottomof a company’s hierarchy—the presumed stressors being the menial duties they're tasked with and their lack of say in defining the scope of their jobs.
But it turns out that middle managers have it worse. In a new study from researchers at Columbia University, of nearly 22,000 full-time workers (from a dataset from the National Epidemiological Survey on Alcohol and Related Conditions), they saw that 18 percent of supervisors and managers reported symptoms of depression. For blue-collar workers, that figure was 12 percent, and for owners and executives, it was only 11 percent.
It is not too late to strengthen the Iran deal, a prominent critic says.
It appears likely, as of this writing, that Barack Obama will be victorious in his fight to implement the Iran nuclear deal negotiated by his secretary of state, John Kerry. Republicans in Congress don’t appear to have the votes necessary to void the agreement, and Benjamin Netanyahu’s campaign to subvert Obama may be remembered as one of the more counterproductive and shortsighted acts of an Israeli prime minister since the rebirth of the Jewish state 67 years ago.
Things could change, of course, and the Iranian regime, which is populated in good part by extremists, fundamentalist theocrats, and supporters of terrorism, could do something monumentally stupid in the coming weeks that could force on-the-fence Democrats to side with their Republican adversaries (remember the Café Milano fiasco, anyone?). But, generally speaking, the Obama administration, and its European allies, seem to have a clearer path to implementation than they had at the beginning of the month.

All hail ¯\_(ツ)_/¯.
In its 11 strokes, the symbol encapsulates what it’s like to be an individual on the Internet. With raised arms and a half-turned smile, it exudes the melancholia, the malaise, the acceptance, and (finally) the embrace of knowing that something’s wrong on the Internet and you can’t do anything about it.
As Kyle Chayka writes in a new history of the symbol at The Awl, the meaning of the “the shruggie” is always two, if not three- or four-, fold. ¯\_(ツ)_/¯ represents nihilism, “bemused resignation,” and “a Zen-like tool to accept the chaos of universe.” It is Sisyphus in unicode. I use it at least 10 times a day.
For a long time, however, I used it with some difficulty. Unlike better-known emoticons like :) or ;), ¯\_(ツ)_/¯ borrows characters from the Japanese syllabary called katakana. That makes it a kaomoji, a Japanese emoticon; it also makes it, on Western alphabetical keyboards at least, very hard to type. But then I found a solution, and it saves me having to google “smiley sideways shrug” every time I want to quickly rail at the world’s inherent lack of meaning.
