A Media Vow of Election Night Restraint Despite Social Media Clamor

This has been the year of the big media gaffe.

NBC News edited a 911 tape of George Zimmerman in a way that implied race as a factor in the Trayvon Martin shooting. CNN and Fox News falsely reported that the Supreme Court had struck down the individual mandate at the heart of the Obama administration’s health care law. ABC News wrongly suggested a link between a mass shooting in Colorado and the Tea Party. Just last week during the storm, CNN repeated a false rumor about flooding at the New York Stock Exchange.

Now the media are gearing up for election night, the finale of the year’s biggest story. It’s a chance to regain some credibility — presuming, of course, that television networks and other news organizations get their state-by-state projections right. They all say they will, still mindful of the mistakes made in 2000, when the networks prematurely called Florida for Al Gore and then George W. Bush.

The same precautions that were put in place after 2000 will be in place again this Tuesday. At NBC, for instance, the statisticians at the “decision desk” that makes projections “are literally sealed off from the rest of us,” said Mark Lukasiewicz, the senior vice president of specials for NBC News.

Different this time will be the level of noise on the Web, where armchair and professional pundits alike will react to the election results in real time. On election night in 2008, a few Web sites, including Slate and Time.com, stated the obvious — that Barack Obama was going to win the presidency — well before the TV networks and major newspapers said so. In large part that’s because the networks and newspapers were waiting for the polls to close on the West Coast.

They will abide by the same principle again on Tuesday night, ruling out any such pronouncement before 11 p.m. Eastern. But more Web sites and individual users will most likely try to call the race early, creating a cacophony on social networking sites like Facebook and Twitter.

A memo on Saturday to employees of The Associated Press, the country’s biggest news wire service, asked them to refrain from adding to the noise by posting to Twitter about other news outlets’ calls. “If A.P. has not called a particular state or race, it’s because we have specifically decided not to, based on the expertise and data we have spent years developing,” the memo read.

In calling a state for Mr. Obama or Mitt Romney, news organizations will consider several data sources, including exit poll results and raw vote totals — “a brain trust of data,” said Ingrid Ciprian-Matthews, the vice president for news for CBS News.

Executives at the major networks said in interviews that they don’t expect to be able to project a winner at 11 p.m. this year, given the closeness of the presidential race in several swing states. “I’m not even going to guess what time it will be,” said Marc Burstein, the senior executive producer for special events at ABC News. He predicted an abundance of caution this year because of the trend of early voting in many states.

For election night ABC is uniquely situated in Times Square, which filled up with supporters of Mr. Obama on election night in 2008. This time, too, “I expect a gigantic crowd,” Mr. Burstein said. NBC is expecting the same at Rockefeller Plaza, which it has re-christened Democracy Plaza with exhibits and video screens, just as it did in 2004 and 2008.

All of the executives interviewed said they would be entirely comfortable making projections after their competitors. “In a close contest, we’ll simply wait,” said Sam Feist, the Washington bureau chief for CNN. And all of them cited the journalism chestnut that it’s better to be right than first. “It’s always lovely when the two coincide,” said Ms. Ciprian-Matthews of CBS, “but everybody here is absolutely on the same page: accuracy comes first.”

Fox News did not respond to an interview request.

CNN, which was criticized for crowding its studio with anchors and analysts in 2008, will have more reporters in the field this time, including a half-dozen in Ohio alone. Reprising what it called “ballot cams” on primary nights, CNN will have crews at “key voting and vote-counting locations” in battleground states, Mr. Feist said.

“We proved during the primaries that doing real reporting on those nights can make a difference,” he said.

No matter the outcome, some partisans will claim that the election is illegitimate, if the election year rhetoric is to be believed. Continuing an effort that started in 2004, networks and other news outlets will ask the public to alert them to voter irregularities and allegations of voter suppression. “We have an entire team working on those stories,” Mr. Lukasiewicz of NBC said.

Dozens of news and opinion Web sites will offer essentially live coverage on election night, some with TV-like newscasts and others with live blogs. But the biggest audiences are still expected to tune to the big three broadcast networks, ABC, CBS and NBC, and the big three cable news networks, Fox News, MSNBC and CNN.

Four years ago, Brian Williams was the anchor on NBC, Charles Gibson on ABC and Katie Couric on CBS. Mr. Williams is back for his second presidential election night as anchor, but Mr. Gibson, who retired three years ago, will not; heading the coverage instead will be the pair that sat alongside him in 2008, Diane Sawyer and George Stephanopoulos. Ms. Couric, now of ABC, will join them from time to time with social media reaction — a role that did not exist on the network’s coverage last time.

On CBS, Scott Pelley will anchor his first presidential election night. It’s also the first time for Rachel Maddow, on MSNBC, and Bret Baier and Megyn Kelly, on Fox News. On PBS, Gwen Ifill and Judy Woodruff will make up national television’s first two-woman anchor team on election night.

Half a dozen smaller channels will also have hours of live election talk, as will countless local stations — paid for in part by the revenue from innumerable election ads. Discussing the extent of the coverage, Mr. Feist of CNN said, “You cannot find an available high-definition satellite path for Tuesday night in this country. There are none left. The country is at capacity.”

A Wheelchair Tour of Morningside College in Sioux City, Iowa

THE specially equipped Dodge Sprinter pulled into the Morningside College parking lot, transporting my campus guide and his Quickie 646 SE motorized wheelchair. Alex Watters was returning to this small liberal arts college in Sioux City, Iowa, for a wheelchair tour of the campus he had navigated as an undergraduate. Our mission was to understand some of the challenges faced by students with a physical disability for a book I was writing on the first-year college experience.

I stuck my hand out. Alex could raise his arm but had no mobility in his hands, so I shook his outstretched fist. Freshman year, he had damaged his spinal cord in a diving accident and lost the use of his legs and hands. “Ready to go?” he asked as I grabbed my manually operated wheelchair, on loan from the nursing department.

“Ready as ever,” I said, not altogether sure how to operate the thing. As I struggled to get over the tiny ribbon of tar between the parking lot and sidewalk, Alex zipped around the lot doing wheelies, as if to say, “You have no idea what you’re in for.”

Motoring backward while talking, like an admissions office tour guide, he was contagiously optimistic. “Sure, I have challenges now,” he said, “but I’m not going to let them take over my life.”

ALEX WATTERS comes from Okoboji, a small town in the northwest corner of Iowa, on the border with Minnesota. He had applied to the University of Iowa and Drake but chose Morningside because he was heavily recruited to play golf. He had been captain of his high school team junior and senior years. When he arrived on campus — it was fall 2004 — he was full of excitement and expectation.

The second week there, Danielle Westphal — a classmate with whom he had won a dance contest during orientation — invited him to a family get-together on Lake Okoboji. He and a friend drove up to the cabin, arriving at about 10 p.m. As the guests toasted marshmallows around a bonfire, Alex and his hostess’s younger brother decided to go for a swim. The weather was beginning to get cold. He figured this would be his last swim of the season.

The two of them changed into their trunks and walked 150 feet out onto the dock. A gust of wind blew, and Alex’s hat flew off, landing near a boat hoist. He took off his shirt and dived in after it. But there was a sandbar. The water was only 18 inches deep. He heard his neck snap.

“I remember laying face-first underwater,” Alex said, a crack in his voice. “At first I tried to start swimming, but of course I couldn’t move. I thought, this was it. I’m a pretty religious person, so I was thinking, ‘I’m O.K. with this if it happens.’ And then I blacked out.”

At first the young boy thought Alex was playing a joke on him. Then he sensed something was terribly wrong. He ran back to the cabin to get help. They came running, and Danielle jumped into the water feetfirst and knelt beside Alex. He had now been under water more than two minutes. She turned him over and gave him mouth-to-mouth resuscitation. E.M.S. arrived, and from the local hospital he was quickly airlifted to Mercy Medical Center in Sioux City.

“Next thing I remember are Mom and Dad and our pastor standing by my bed and the surgeon telling them about the operation I would soon have,” he told me. His spinal cord wasn’t severed but pinched. “Your spinal cord is like a banana,” Alex said. “If you bend it severely enough it won’t necessarily break but it will be permanently damaged.”

After surgery to stabilize the vertebrae in his neck, Alex underwent therapy for six months at a rehabilitation hospital in Denver. I asked him what he was feeling at this point. He and his parents had become interested in stem cell research, and the possibility he would someday walk again. “But I really didn’t want to live my life hoping I would walk again when the chances were I might not,” he said. “Even at that point, I was pretty happy with who I was and even then I was thinking about the possibility of returning to college.”

He took courses at Iowa Lakes Community College that summer, and the next fall returned to Morningside to resume his first year.

Massive Open Online Courses Are Multiplying at a Rapid Pace

Clockwise, from top left: an online course in circuits and electronics with an M.I.T. professor (edX); statistics, Stanford (Udacity); machine learning, Stanford (Coursera); organic chemistry, University of Illinois, Urbana (Coursera).

IN late September, as workers applied joint compound to new office walls, hoodie-clad colleagues who had just met were working together on deadline. Film editors, code-writing interns and “edX fellows” — grad students and postdocs versed in online education — were translating videotaped lectures into MOOCs, or massive open online courses. As if anyone needed reminding, a row of aqua Post-its gave the dates the courses would “go live.”

The paint is barely dry, yet edX, the nonprofit start-up from Harvard and the Massachusetts Institute of Technology, has 370,000 students this fall in its first official courses. That’s nothing. Coursera, founded just last January, has reached more than 1.7 million — growing “faster than Facebook,” boasts Andrew Ng, on leave from Stanford to run his for-profit MOOC provider.

“This has caught all of us by surprise,” says David Stavens, who formed a company called Udacity with Sebastian Thrun and Michael Sokolsky after more than 150,000 signed up for Dr. Thrun’s “Introduction to Artificial Intelligence” last fall, starting the revolution that has higher education gasping. A year ago, he marvels, “we were three guys in Sebastian’s living room and now we have 40 employees full time.”

“I like to call this the year of disruption,” says Anant Agarwal, president of edX, “and the year is not over yet.”

MOOCs have been around for a few years as collaborative techie learning events, but this is the year everyone wants in. Elite universities are partnering with Coursera at a furious pace. It now offers courses from 33 of the biggest names in postsecondary education, including Princeton, Brown, Columbia and Duke. In September, Google unleashed a MOOC-building online tool, and Stanford unveiled Class2Go with two courses.

Nick McKeown is teaching one of them, on computer networking, with Philip Levis (the one with a shock of magenta hair in the introductory video). Dr. McKeown sums up the energy of this grand experiment when he gushes, “We’re both very excited.” Casually draped over auditorium seats, the professors also acknowledge that they are not exactly sure how this MOOC stuff works.

“We are just going to see how this goes over the next few weeks,” says Dr. McKeown.

WHAT IS A MOOC ANYWAY?

Traditional online courses charge tuition, carry credit and limit enrollment to a few dozen to ensure interaction with instructors. The MOOC, on the other hand, is usually free, credit-less and, well, massive.

Because anyone with an Internet connection can enroll, faculty can’t possibly respond to students individually. So the course design — how material is presented and the interactivity — counts for a lot. As do fellow students. Classmates may lean on one another in study groups organized in their towns, in online forums or, the prickly part, for grading work.

The evolving form knits together education, entertainment (think gaming) and social networking. Unlike its antecedent, open courseware — usually written materials or videotapes of lectures that make you feel as if you’re spying on a class from the back of the room — the MOOC is a full course made with you in mind.

The medium is still the lecture. Thanks to Khan Academy’s free archive of snappy instructional videos, MOOC makers have gotten the memo on the benefit of brevity: 8 to 12 minutes is typical. Then — this is key — videos pause perhaps twice for a quiz to make sure you understand the material or, in computer programming, to let you write code. Feedback is electronic. Teaching assistants may monitor discussion boards. There may be homework and a final exam.

The MOOC certainly presents challenges. Can learning be scaled up this much? Grading is imperfect, especially for nontechnical subjects. Cheating is a reality. “We found groups of 20 people in a course submitting identical homework,” says David Patterson, a professor at the University of California, Berkeley, who teaches software engineering, in a tone of disbelief at such blatant copying; Udacity and edX now offer proctored exams.

Some students are also ill prepared for the university-level work. And few stick with it. “Signing up for a class is a lightweight process,” says Dr. Ng. It might take just five minutes, assuming you spend two devising a stylish user name. Only 46,000 attempted the first assignment in Dr. Ng’s course on machine learning last fall. In the end, he says, 13,000 completed the class and earned a certificate — from him, not Stanford.

This article has been revised to reflect the following correction:

Correction: November 4, 2012

An earlier version of this article, using information from Coursera, misidentified the source of a study of peer grading in a Princeton sociology MOOC. The study is by Mitchell Duneier, the course’s teacher, not Coursera. Also, the student work was regraded by Professor Duneier and his assistants, not by Princeton instructors. Results have not been released. Also, the article misspelled the surname of a Udacity co-founder. He is Michael Sokolsky, not Sokolosky.

Syrian Rebels Claim to Kill Dozens of Soldiers

SANA, via Associated Press

An image released by Syria’s official news agency showed Damascus residents gathering at the scene of a blast on Monday.

BEIRUT, Lebanon — Syria was convulsed by one of the most violent days in months on Monday, with heavy fighting reported around Palestinian neighborhoods in southern Damascus, at least two car-bomb explosions and strikes by government aircraft on numerous rebel targets.

Sharply conflicting accounts emerged from the government and the rebels on the toll from a car bombing near the central city of Hama, with the rebels reporting dozens of soldiers dead and the government saying just two civilians were killed.

The Syrian Observatory for Human Rights, a group based in Britain with a network of contacts inside Syria, said that Jabhet al-Nusra, a jihadist organization, and other rebel groups in the region collaborated in a suicide car bombing of a government checkpoint in a village near Hama, killing at least 50 soldiers.

“They targeted one of the biggest checkpoints in the region. It’s a big building where the regime forces were headquartered,” said Ahmad Raadoun, a member of the Free Syrian Army in the Hama suburbs, who was reached via Skype.

Mr. Raadoun, who said he was about 20 miles from the village of Ziyara, where the attack took place, said the bomb caused extensive casualties and other damage in what he described as a “big operation.”

The official news agency, SANA, said the explosion, outside a government building called the Rural Development Center, was orchestrated by terrorist groups and left 2 civilians dead and 10 wounded. The government has repeatedly labeled opposition groups seeking to topple President Bashar al-Assad as terrorist organizations.

The reasons for such divergent accounts could not be immediately ascertained.

Checkpoints in rural areas often serve as rudimentary bases for the government, with large numbers of men and matériel stationed in them to carry the fight across the province.

Another car bombing was reported in Mazzeh 86, a Damascus neighborhood on the slopes below the presidential palace, home to many members of the security forces. The forces are dominated by members of Mr. Assad’s Alawite minority, which controls the country.

The Free Syrian Army claimed responsibility for that attack, saying in a statement that its fighters had targeted officers as well as members of the armed militias who fight for the government. The statement, posted on Facebook, claimed a large number of casualties but did not give any figures.

The Syrian Observatory said the bomb, which it described as a booby-trapped car that exploded in Bride Square, killed 5 people and wounded more than 30, some of them critically.

Pictures posted on Facebook showed a large column of smoke rising from the area.

Damascus residents reached by telephone said that they were trying to flee the heavy fighting, but that there was so much going on in every direction that they did not quite know where to run.

“There is very, very intense shelling on southern Damascus right now,” said an activist reached by Skype who goes by Abu Qays al-Shami. At least 10 people were killed as government helicopters and tanks blasted the area, he said.

Residents said the fighting had erupted in and around the Yarmouk camp in southern Damascus, the center of Palestinian life in Syria for decades. Many Palestinians have sided with the nearly 20-month-old anti-Assad uprising, but the Popular Front for the Liberation of Palestine-General Command, a splinter Palestinian group long supported by the government, still backs Mr. Assad. The fighting erupted between the organization and government opponents.

Elsewhere in southern Damascus, government helicopters were shelling the restive neighborhood of Hajjar al-Aswad, a target of frequent attacks in recent weeks, according to the Local Coordinating Committees, an anti-Assad activist group that keeps track of casualties. SANA said five people were killed in Yarmouk, including a woman and three children, when a mortar shell hit a public minibus. The agency blamed terrorist organizations.

In its daily roundup of violence around the country, SANA also said that government forces clashed with opposition groups in the eastern city of Deir ez-Zour and in Aleppo, the northern city that has been a battleground since midsummer.

Activist organizations reported a number of airstrikes around the country.

One extremely graphic video posted from the village of Kafrnabel, near Idlib, shows bloodied victims dumped into a truck in the aftermath of what was described as an aerial assault. A shot of the main street shows flames leaping from vehicles and residents running around in panic. At least five men and one woman died, the Syrian Observatory said, but more victims were believed buried under the rubble. Video accounts cannot be independently confirmed.

Hania Mourtada contributed reporting from Beirut, and Hala Droubi from Dubai, United Arab Emirates.

Google Casts a Big Shadow on Smaller Web Sites

Annie Tritt for The New York Times

Jeffrey G. Katz, the chief executive of Wize Commerce, seen with employees. He says that about 60 percent of the traffic for the company’s Nextag comparison-shopping site comes from Google.

In a geeky fire drill, engineers and outside consultants at Nextag scrambled to see if the problem was its own fault. Maybe some inadvertent change had prompted Google’s algorithm to demote Nextag when a person typed in shopping-related search terms like “kitchen table” or “lawn mower.”

But no, the engineers determined. And traffic from Google’s search engine continued to decline, by half.

Nextag’s response? It doubled its spending on Google paid search advertising in the last five months.

The move was costly but necessary to retain shoppers, Mr. Katz says, because an estimated 60 percent of Nextag’s traffic comes from Google, both from free search and paid search ads, which are ads that are related to search results and appear next to them. “We had to do it,” says Mr. Katz, chief executive of Wize Commerce, owner of Nextag. “We’re living in Google’s world.”

Regulators in the United States and Europe are conducting sweeping inquiries of Google, the dominant Internet search and advertising company. Google rose by technological innovation and business acumen; in the United States, it has 67 percent of the search market and collects 75 percent of search ad dollars. Being big is no crime, but if a powerful company uses market muscle to stifle competition, that is an antitrust violation.

So the government is focusing on life in Google’s world for the sprawling economic ecosystem of Web sites that depend on their ranking in search results. What is it like to live this way, in a giant’s shadow? The experience of its inhabitants is nuanced and complex, a blend of admiration and fear.

The relationship between Google and Web sites, publishers and advertisers often seems lopsided, if not unfair. Yet Google has also provided and nurtured a landscape of opportunity. Its ecosystem generates $80 billion a year in revenue for 1.8 million businesses, Web sites and nonprofit organizations in the United States alone, it estimates.

The government’s scrutiny of Google is the most exhaustive investigation of a major corporation since the pursuit of Microsoft in the late 1990s.

The staff of the Federal Trade Commission has recommended preparing an antitrust suit against Google, according to people briefed on the inquiry, who spoke on the condition they not be identified. But the commissioners must vote to proceed. Even if they do, the government and Google could settle.

Google has drawn the attention of antitrust officials as it has moved aggressively beyond its dominant product — search and search advertising — into fields like online commerce and local reviews. The antitrust issue is whether Google uses its search engine to favor its offerings like Google Shopping and Google Plus Local over rivals.

For policy makers, Google is a tough call.

“What to do with an attractive monopolist, like Google, is a really challenging issue for antitrust,” says Tim Wu, a professor at Columbia Law School and a former senior adviser to the F.T.C. “The goal is to encourage them to stay in power by continuing to innovate instead of excluding competitors.”

SPEAKING at a Google Zeitgeist conference in Arizona last month, Larry Page, the company’s co-founder and chief executive, said he understood the government scrutiny of his company, given Google’s size and reach. “There’s very many decisions we make that really impact a lot of people,” he acknowledged.

The main reason is that Google is continually adjusting its search algorithm — the smart software that determines the relevance, ranking and presentation of search results, typically links to other Web sites.

Google says it makes the changes to improve its service, and has long maintained that its algorithm weeds out low-quality sites and shows the most useful results, whether or not they link to Google products.

“Our first and highest goal has to be to get the user the information they want as quickly and easily as possible,” says Matt Cutts, leader of the Web spam team at Google.

But Google’s algorithm is secret, and changes can leave Web sites scrambling.

Consider Vote-USA.org, a nonprofit group started in 2003. It provides online information for voters to avoid the frustration of arriving at a polling booth and barely recognizing half the names on the ballot. The site posts free sample ballots for federal, state and local elections with candidates’ pictures, biographies and views on issues.

In the 2004 and 2006 elections, users created tens of thousands of sample ballots. By 2008, traffic had fallen sharply, says Ron Kahlow, who runs Vote-USA.org, because “we dropped off the face of the map on Google.”

As founder of a search-engine optimization company and a recipient of grants that Google gives nonprofits to advertise free, Mr. Kahlow knows a thing or two about how to operate in Google’s world. He pored over Google’s guidelines for Web sites, made changes and e-mailed Google. Yet he received no response.

“I lost all donations to support the operation,” he said. “It was very, very painful.”

A breakthrough came through a personal connection. A friend of Mr. Kahlow knew Ed Black, chief executive of the Computer & Communications Industry Association, whose members include Google. Mr. Black made an inquiry on Mr. Kahlow’s behalf, and a Google engineer investigated.

Opinion: Seeing Things? Hearing Things? Many of Us Do

HALLUCINATIONS are very startling and frightening: you suddenly see, or hear or smell something — something that is not there. Your immediate, bewildered feeling is, what is going on? Where is this coming from? The hallucination is convincingly real, produced by the same neural pathways as actual perception, and yet no one else seems to see it. And then you are forced to the conclusion that something — something unprecedented — is happening in your own brain or mind. Are you going insane, getting dementia, having a stroke?

In other cultures, hallucinations have been regarded as gifts from the gods or the Muses, but in modern times they seem to carry an ominous significance in the public (and also the medical) mind, as portents of severe mental or neurological disorders. Having hallucinations is a fearful secret for many people — millions of people — never to be mentioned, hardly to be acknowledged to oneself, and yet far from uncommon. The vast majority are benign — and, indeed, in many circumstances, perfectly normal. Most of us have experienced them from time to time, during a fever or with the sensory monotony of a desert or empty road, or sometimes, seemingly, out of the blue.

Many of us, as we lie in bed with closed eyes, awaiting sleep, have so-called hypnagogic hallucinations — geometric patterns, or faces, sometimes landscapes. Such patterns or scenes may be almost too faint to notice, or they may be very elaborate, brilliantly colored and rapidly changing — people used to compare them to slide shows.

At the other end of sleep are hypnopompic hallucinations, seen with open eyes, upon first waking. These may be ordinary (an intensification of color perhaps, or someone calling your name) or terrifying (especially if combined with sleep paralysis) — a vast spider, a pterodactyl above the bed, poised to strike.

Hallucinations (of sight, sound, smell or other sensations) can be associated with migraine or seizures, with fever or delirium. In chronic disease hospitals, nursing homes, and I.C.U.’s, hallucinations are often a result of too many medications and interactions between them, compounded by illness, anxiety and unfamiliar surroundings.

But hallucinations can have a positive and comforting role, too — this is especially true with bereavement hallucinations, seeing the face or hearing the voice of one’s deceased spouse, siblings, parents or child — and may play an important part in the mourning process. Such bereavement hallucinations frequently occur in the first year or two of bereavement, when they are most “needed.”

Working in old-age homes for many years, I have been struck by how many elderly people with impaired hearing are prone to auditory and, even more commonly, musical hallucinations — involuntary music in their minds that seems so real that at first they may think it is a neighbor’s stereo.

People with impaired sight, similarly, may start to have strange, visual hallucinations, sometimes just of patterns but often more elaborate visions of complex scenes or ranks of people in exotic dress. Perhaps 20 percent of those losing their vision or hearing may have such hallucinations.

I was called in to see one patient, Rosalie, a blind lady in her 90s, when she started to have visual hallucinations; the staff psychiatrist was also summoned. Rosalie was concerned that she might be having a stroke or getting Alzheimer’s or reacting to some medication. But I was able to reassure her that nothing was amiss neurologically. I explained to her that if the visual parts of the brain are deprived of actual input, they are hungry for stimulation and may concoct images of their own. Rosalie was greatly relieved by this, and delighted to know that there was even a name for her condition: Charles Bonnet syndrome. “Tell the nurses,” she said, drawing herself up in her chair, “that I have Charles Bonnet syndrome!”

Rosalie asked me how many people had C.B.S., and I told her hundreds of thousands, perhaps, in the United States alone. I told her that many people were afraid to mention their hallucinations. I described a recent study of elderly blind patients in the Netherlands which found that only a quarter of people with C.B.S. mentioned it to their doctors — the others were too afraid or too ashamed. It is only when physicians gently inquire (often avoiding the word “hallucination”) that people feel free to admit seeing things that are not there — despite their blindness.

Rosalie was indignant at this, and said, “You must write about it — tell my story!” I do tell her story, at length, in my book on hallucinations, along with the stories of many others. Most of these people have been reluctant to admit to their hallucinations. Often, when they do, they are misdiagnosed or undiagnosed — told that it’s nothing, or that their condition has no explanation.

Misdiagnosis is especially common if people admit to “hearing voices.” In a famous 1973 study by the Stanford psychologist David Rosenhan, eight “pseudopatients” presented themselves at various hospitals across the country, saying that they “heard voices.” All behaved normally otherwise, but were nonetheless determined to be (and treated as) schizophrenic (apart from one, who was given the diagnosis of “manic-depressive psychosis”). In this and follow-up studies, Professor Rosenhan demonstrated convincingly that auditory hallucinations and schizophrenia were synonymous in the medical mind.

WHILE many people with schizophrenia do hear voices at certain times in their lives, the inverse is not true: most people who hear voices (as much as 10 percent of the population) are not mentally ill. For them, hearing voices is a normal mode of experience.

My patients tell me about their hallucinations because I am open to hearing about them, because they know me and trust that I can usually run down the cause of their hallucinations. For the most part, these experiences are unthreatening and, once accommodated, even mildly diverting.

David Stewart, a Charles Bonnet syndrome patient with whom I corresponded, writes of his hallucinations as being “altogether friendly,” and imagines his eyes saying: “Sorry to have let you down. We recognize that blindness is no fun, so we’ve organized this small syndrome, a sort of coda to your sighted life. It’s not much, but it’s the best we can manage.”

Mr. Stewart has been able to take his hallucinations in good humor, since he knows they are not a sign of mental decline or madness. For too many patients, though, the shame, the secrecy, the stigma, persists.

Opinion: Seeing Things? Hearing Things? Many of Us Do

HALLUCINATIONS are very startling and frightening: you suddenly see, or hear or smell something — something that is not there. Your immediate, bewildered feeling is, what is going on? Where is this coming from? The hallucination is convincingly real, produced by the same neural pathways as actual perception, and yet no one else seems to see it. And then you are forced to the conclusion that something — something unprecedented — is happening in your own brain or mind. Are you going insane, getting dementia, having a stroke?

In other cultures, hallucinations have been regarded as gifts from the gods or the Muses, but in modern times they seem to carry an ominous significance in the public (and also the medical) mind, as portents of severe mental or neurological disorders. Having hallucinations is a fearful secret for many people — millions of people — never to be mentioned, hardly to be acknowledged to oneself, and yet far from uncommon. The vast majority are benign — and, indeed, in many circumstances, perfectly normal. Most of us have experienced them from time to time, during a fever or with the sensory monotony of a desert or empty road, or sometimes, seemingly, out of the blue.

Many of us, as we lie in bed with closed eyes, awaiting sleep, have so-called hypnagogic hallucinations — geometric patterns, or faces, sometimes landscapes. Such patterns or scenes may be almost too faint to notice, or they may be very elaborate, brilliantly colored and rapidly changing — people used to compare them to slide shows.

At the other end of sleep are hypnopompic hallucinations, seen with open eyes, upon first waking. These may be ordinary (an intensification of color perhaps, or someone calling your name) or terrifying (especially if combined with sleep paralysis) — a vast spider, a pterodactyl above the bed, poised to strike.

Hallucinations (of sight, sound, smell or other sensations) can be associated with migraine or seizures, with fever or delirium. In chronic disease hospitals, nursing homes, and I.C.U.’s, hallucinations are often a result of too many medications and interactions between them, compounded by illness, anxiety and unfamiliar surroundings.

But hallucinations can have a positive and comforting role, too — this is especially true with bereavement hallucinations, seeing the face or hearing the voice of one’s deceased spouse, siblings, parents or child — and may play an important part in the mourning process. Such bereavement hallucinations frequently occur in the first year or two of bereavement, when they are most “needed.”

Working in old-age homes for many years, I have been struck by how many elderly people with impaired hearing are prone to auditory and, even more commonly, musical hallucinations — involuntary music in their minds that seems so real that at first they may think it is a neighbor’s stereo.

People with impaired sight, similarly, may start to have strange, visual hallucinations, sometimes just of patterns but often more elaborate visions of complex scenes or ranks of people in exotic dress. Perhaps 20 percent of those losing their vision or hearing may have such hallucinations.

I was called in to see one patient, Rosalie, a blind lady in her 90s, when she started to have visual hallucinations; the staff psychiatrist was also summoned. Rosalie was concerned that she might be having a stroke or getting Alzheimer’s or reacting to some medication. But I was able to reassure her that nothing was amiss neurologically. I explained to her that if the visual parts of the brain are deprived of actual input, they are hungry for stimulation and may concoct images of their own. Rosalie was greatly relieved by this, and delighted to know that there was even a name for her condition: Charles Bonnet syndrome. “Tell the nurses,” she said, drawing herself up in her chair, “that I have Charles Bonnet syndrome!”

Rosalie asked me how many people had C.B.S., and I told her hundreds of thousands, perhaps, in the United States alone. I told her that many people were afraid to mention their hallucinations. I described a recent study of elderly blind patients in the Netherlands which found that only a quarter of people with C.B.S. mentioned it to their doctors — the others were too afraid or too ashamed. It is only when physicians gently inquire (often avoiding the word “hallucination”) that people feel free to admit seeing things that are not there — despite their blindness.

Rosalie was indignant at this, and said, “You must write about it — tell my story!” I do tell her story, at length, in my book on hallucinations, along with the stories of many others.

Massive Open Online Courses Are Multiplying at a Rapid Pace

Clockwise, from top left: an online course in circuits and electronics with an M.I.T. professor (edX); statistics, Stanford (Udacity); machine learning, Stanford (Coursera); organic chemistry, University of Illinois, Urbana (Coursera).

IN late September, as workers applied joint compound to new office walls, hoodie-clad colleagues who had just met were working together on deadline. Film editors, code-writing interns and “edX fellows” — grad students and postdocs versed in online education — were translating videotaped lectures into MOOCs, or massive open online courses. As if anyone needed reminding, a row of aqua Post-its gave the dates the courses would “go live.”

The paint is barely dry, yet edX, the nonprofit start-up from Harvard and the Massachusetts Institute of Technology, has 370,000 students this fall in its first official courses. That’s nothing. Coursera, founded just last January, has reached more than 1.7 million — growing “faster than Facebook,” boasts Andrew Ng, on leave from Stanford to run his for-profit MOOC provider.

“This has caught all of us by surprise,” says David Stavens, who formed a company called Udacity with Sebastian Thrun and Mike Sokolosky after more than 150,000 signed up for Dr. Thrun’s “Introduction to Artificial Intelligence” last fall, starting the revolution that has higher education gasping. A year ago, he marvels, “we were three guys in Sebastian’s living room and now we have 40 employees full time.”

“I like to call this the year of disruption,” says Anant Agarwal, president of edX, “and the year is not over yet.”

MOOCs have been around for a few years as collaborative techie learning events, but this is the year everyone wants in. Elite universities are partnering with Coursera at a furious pace. It now offers courses from 33 of the biggest names in postsecondary education, including Princeton, Brown, Columbia and Duke. In September, Google unleashed a MOOC-building online tool, and Stanford unveiled Class2Go with two courses.

Nick McKeown is teaching one of them, on computer networking, with Philip Levis (the one with a shock of magenta hair in the introductory video). Dr. McKeown sums up the energy of this grand experiment when he gushes, “We’re both very excited.” Casually draped over auditorium seats, the professors also acknowledge that they are not exactly sure how this MOOC stuff works.

“We are just going to see how this goes over the next few weeks,” says Dr. McKeown.

WHAT IS A MOOC ANYWAY?

Traditional online courses charge tuition, carry credit and limit enrollment to a few dozen to ensure interaction with instructors. The MOOC, on the other hand, is usually free, credit-less and, well, massive.

Because anyone with an Internet connection can enroll, faculty can’t possibly respond to students individually. So the course design — how material is presented and the interactivity — counts for a lot. As do fellow students. Classmates may lean on one another in study groups organized in their towns, in online forums or, the prickly part, for grading work.

The evolving form knits together education, entertainment (think gaming) and social networking. Unlike its antecedent, open courseware — usually written materials or videotapes of lectures that make you feel as if you’re spying on a class from the back of the room — the MOOC is a full course made with you in mind.

The medium is still the lecture. Thanks to Khan Academy’s free archive of snappy instructional videos, MOOC makers have gotten the memo on the benefit of brevity: 8 to 12 minutes is typical. Then — this is key — videos pause perhaps twice for a quiz to make sure you understand the material or, in computer programming, to let you write code. Feedback is electronic. Teaching assistants may monitor discussion boards. There may be homework and a final exam.

The MOOC certainly presents challenges. Can learning be scaled up this much? Grading is imperfect, especially for nontechnical subjects. Cheating is a reality. “We found groups of 20 people in a course submitting identical homework,” says David Patterson, a professor at the University of California, Berkeley, who teaches software engineering, in a tone of disbelief at such blatant copying; Udacity and edX now offer proctored exams.

Some students are also ill prepared for the university-level work. And few stick with it. “Signing up for a class is a lightweight process,” says Dr. Ng. It might take just five minutes, assuming you spend two devising a stylish user name. Only 46,000 attempted the first assignment in Dr. Ng’s course on machine learning last fall. In the end, he says, 13,000 completed the class and earned a certificate — from him, not Stanford.

Benghazi Attack Raises Doubts About U.S. Abilities in Region

Esam Omran Al-Fetori/Reuters

The attack at the American Mission on Sept. 11, seen here, and an annex in Benghazi, Libya, points to a limitation in the capabilities of the American military command responsible for countries swept up in the Arab Spring.

WASHINGTON — About three hours after the American diplomatic mission in Benghazi, Libya, came under attack, the Pentagon issued an urgent call for an array of quick-reaction forces, including an elite Special Forces team that was on a training mission in Croatia.

The team dropped what it was doing and prepared to move to the Sigonella naval air station in Sicily, a short flight from Benghazi and other hot spots in the region. By the time the unit arrived at the base, however, the surviving Americans at the Benghazi mission had been evacuated to Tripoli, and Ambassador J. Christopher Stevens and three other Americans were dead.

The assault, on the anniversary of the Sept. 11, 2001, attacks on the United States, has already exposed shortcomings in the Obama administration’s ability to secure diplomatic missions and act on intelligence warnings. But this previously undisclosed episode, described by several American officials, points to a limitation in the capabilities of the American military command responsible for a large swath of countries swept up in the Arab Spring.

At the heart of the issue is the Africa Command, established in 2007, well before the Arab Spring uprisings and before an affiliate of Al Qaeda became a major regional threat. It did not have on hand what every other regional combatant command has: its own force able to respond rapidly to emergencies — a Commanders’ In-Extremis Force, or C.I.F.

To respond to the Benghazi attack, the Africa Command had to borrow the C.I.F. that belongs to the European Command, because its own force is still in training. It also had no AC-130 gunships or armed drones readily available.

As officials in the White House and Pentagon scrambled to respond to the torrent of reports pouring out from Libya — with Mr. Stevens missing and officials worried that he might have been taken hostage — they took the extraordinary step of sending elite Delta Force commandos, with their own helicopters and ground vehicles, from their base at Fort Bragg, N.C., to Sicily. Those troops also arrived too late.

“The fact of the matter is these forces were not in place until after the attacks were over,” a Pentagon spokesman, George Little, said on Friday, referring to a range of special operations soldiers and other personnel. “We did respond. The secretary ordered forces to move. They simply were not able to arrive in time.”

An examination of these tumultuous events undercuts the criticism leveled by some Republicans that the Obama administration did not try to respond militarily to the crisis. The attack was not a running eight-hour firefight as some critics have contended, questioning how an adequate response could not be mustered in that time, but rather two relatively short, intense assaults separated by a lull of four hours. But the administration’s response also shows that the forces in the region had not been adequately reconfigured.

The Africa Command was spun off from the European Command. At the time it was set up, the Pentagon thought it would be devoted mostly to training African troops and building military ties with African nations. Because of African sensitivities about an overt American military presence in the region, the command’s headquarters was established in Stuttgart, Germany.

While the other regional commands, including the Pacific Command and the Central Command, responsible for the Middle East and South Asia, have their own specialized quick-reaction forces, the Africa Command has had an arrangement to borrow the European Command’s force when needed. The Africa Command has been building its own team from scratch, and its nascent strike force was in the process of being formed in the United States on Sept. 11, a senior military official said.

“The conversation about getting them closer to Africa has new energy,” the military official said.

Some Pentagon officials said that it was unrealistic to think a quick-reaction force could have been sent in time even if the African Command had one ready to act on the base in Sicily when the attack unfolded, and asserted that such a small force might not have even been effective or the best means to protect an embassy. But critics say there has been a gap in the command’s quick-reaction capability, which the force would have helped fill.

A spokesman for the command declined to comment on how its capabilities might be improved.
