On May 6, the Dow Jones Industrial average was puttering along, trading in a range between 10,600 and 10,800 for most of the day. Then, suddenly around 2:30 pm, the index suddenly dropped 1,000 points in just a few minutes. Panic dulled, and the index perked right back up. But for a few minutes there, half a trillion dollars worth of value had been erased. The incident became known as "the flash crash.".
Regulators, investors, and the public all asked the same question, "WTF?!?" How could our vaunted markets be so brittle? Did anyone know what the hell was going on? All kinds of hypotheses were floated. Hackers! A buggy automated trading program! Something more sinister! No one knew quite what happened, but it was clear that computers trading stocks had something to do with it.
Several government bodies started investigations, including a joint effort between the Securities and Exchange Commission and the Commodities Futures Trading Commission. Of course, everyone was looking for a scapegoat, someone or something to blame. But the latter organization also took steps to address the deeper problems of our markets increasingly being driven by algorithmic, computerized trading.
"The past decade of fragmentation and automation has given rise to a whole new type of professional trading firm: one that uses sophisticated computer algorithms, often running on servers housed right next to exchanges' own machines, and high-speed market data feeds to buy and sell securities in rapid-fire fashion," wrote Michael Peltz in an in-depth investigation of algorithmic trading for Institutional Investor in June. "Some of these high frequency traders place hundreds of millions, even billions, of buy and sell orders a day, continually canceling and replacing them, and are likely to be on the other side of your trade. Not that you'd know who they are -- proprietary trading firms are not required to disclose their identity -- or recognize their names."
We'll be tracking that advisory committee as they go about their work, but what was the first substantive item on their agenda? The flash crash. And the saddest thing is that there is still no clear culprit in the case.
"It was not a fat finger. It was not a
hacker. It was not an algo gone wild," said Richard Gorelick CEO of RGM Advisors, one of those unnamed but important a high-frequency trading firms.
So if it wasn't one of those things, what was it? Gorelick didn't exactly point the finger at anything specific, so much as at complexity itself.
"Complex systems like markets
fail in very complex ways. They do not fail in simple ways because
the simple ways have been thought of," Gorelick said. "We see this not only in markets but in
oil rigs and plane crashes. There is usually a cascading effect of
multiple factors that were at fault."
Among the multiple factors were "real human panic" over the situation in Europe (i.e. Greece), problems at equity firms keeping up with the volume of trades, and slow responses from the stock exchanges.
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.
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.
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.
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.
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.
Every time you shrug, you don’t need to Google, then copy, then paste.

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.
