The Science of Misheard Song Lyrics

Maria Konnikova writes in The New Yorker that mondegreens are funny but they also give us insight into the underlying nature of linguistic processing, how our minds make meaning out of sound, and how in fractions of seconds, we translate a boundless blur of sound into sense. One of the reasons we often mishear song lyrics is that there’s a lot of noise to get through, and we usually can’t see the musicians’ faces. Other times, the misperceptions come from the nature of the speech itself, for example when someone speaks in an unfamiliar accent or when the usual structure of stresses and inflections changes, as it does in a poem or a song. Another common cause of mondegreens is the oronym: word strings in which the sounds can be logically divided multiple ways. One version that Steven Pinker describes goes like this: Eugene O’Neill won a Pullet Surprise. The string of phonetic sounds can be plausibly broken up in multiple ways—and if you’re not familiar with the requisite proper noun, you may find yourself making an error.

Other times, the culprit is the perception of the sound itself: some letters and letter combinations sound remarkably alike, and we need further cues, whether visual or contextual, to help us out. In a phenomenon known as the McGurk effect, people can be made to hear one consonant when a similar one is being spoken. “There’s a bathroom on the right” standing in for “there’s a bad moon on the rise” is a succession of such similarities adding up to two equally coherent alternatives.

Finally along with knowledge, we’re governed by familiarity: we are more likely to select a word or phrase that we’re familiar with, a phenomenon known as Zipf’s law. One of the reasons that “Excuse me while I kiss this guy” substituted for Jimi Hendrix’s “Excuse me while I kiss the sky” remains one of the most widely reported mondegreens of all time can be explained in part by frequency. It’s much more common to hear of people kissing guys than skies.

New Apps Mark the Digital Return of the Rhythm Method

Count natural family planning among the ways young people are hearkening back to the practices of their grandparents as Olga Khazan reports at The Atlantic that new apps are letting women know if they can have sex with their partners without a condom or a contraceptive pill using calendar-based contraception. The underlying motive is not so much trendiness as it is a dissatisfaction with the Pill, which is still the most common form of birth control for women. In a recent CDC study of 12,000 American women, 63 percent of women who stopped using the Pill did so due to its side effects (PDF). And while as of 2010, only about 22 percent of women used “periodic abstinence," an umbrella term that includes counting days, measuring temperature, and tracking cervical mucus to predict fertility, their ranks may grow as new apps and other technologies make it easier to manage the historically error-prone task of measuring, recording, and analyzing one’s cycle in order to stay baby-free.

CycleBeads, for example, is an iPhone app that allows women to track fertility based on the Standard Days Method, a system developed by Georgetown University's Institute for Reproductive Health in which specific days of each woman’s cycle are considered infertile. While the method is not as effective for women who have cycles outside of the 26-32 day range, Leslie Heyer says that its success rate is about 95 percent for “perfect use” and 88 percent for “typical use,” which would mean it beats condoms and falls just short of the Pill. “At first [my husband and I] were worried,” says Kate, a woman who began using CycleBeads nearly three years ago after experiencing weight gain and moodiness on the Pill, “but then we got used to it and have grown to trust it. I honestly can't imagine ever going back on the Pill.”

LA Mayor Proposes Ambitious Earthquake Retrofit Program

The LA Times reports that Ls Angeles Mayor Eric Garcetti has proposed the most ambitious seismic safety regulations in California history that would require owners to retrofit thousands of buildings most at risk of collapse during a major earthquake. "The time for retrofit is now," says Garcetti, adding that the retrofits target buildings “that are known killers. Complacency risks lives. One thing we can’t afford to do is wait.” The mayor’s plan calls for thousands of wood buildings to be retrofitted within five years, and hundreds of concrete buildings to be strengthened within 30. The retrofitting requirements must be approved by the City Council, and would have to be paid for by the building owners, with the costs presumably passed on to tenants and renters. The costs could be significant: $5,000 per unit in vulnerable wooden buildings and $15 per square foot for office buildings, Business owners, who have expressed concern in the past that these kinds of programs may be unaffordable, said the cost of retrofitting some buildings could easily exceed $1 million each. “This will cost us billions of dollars in the private and public sector,” says Garcetti. “But we cannot afford not to do it.”

The last major earthquake in Los Angeles was the 6.7-magnitude Northridge quake, which killed close to 60 people in 1994. But it was not close to the catastrophe that seismologists predict if there is a major shift on the San Andreas fault, and the fact that it has not produced a major quake in recent years has fed a sense of complacency. Seismologists now say a 7.5-magnitude event on the Puente Hills would be "the quake from hell" because it runs right under downtown Los Angeles and have estimated that would kill up to 18,000 people, make several million homeless, and cause up to $250 billion in damage. “We want to keep the city up and running after the earthquake happens,” says Lucy Jones aka "The Earthquake Lady," a seismologist with the United States Geological Survey and something of a celebrity in a city that is very aware of the potential danger of its location. “If everything in this report is enacted, I believe that L.A. will not just survive the next earthquake, but will be able to recover quickly.”

College Video Game Stars Win Fame and Scholarships

Nick Wingfield reports at the NYT that Loc Tran, a top player on the school’s competitive video game team, became a big man on campus at San Jose State University in Northern California after helping San Jose State claw its way to victory in June over California State University, Fullerton, in a tournament watched online by nearly 90,000 people. When the new school year started this fall, classmates’ heads swiveled toward him when professors said his name during roll call. “I thought that was pretty cool,” says Tran. Winning a big video game competitions, also known as e-sports, can sometimes earn players several years’ worth of tuition money and in a possible sign of the future, the athletic department of Robert Morris University Illinois in Chicago created an official video game team this fall, offering the same sort of scholarships given to athletes playing soccer, football and ice hockey.

The rise in e-sports has been so abrupt, many schools have not determined what to make of it. Carter Henderson, a spokesman for the University of Washington’s athletics program, said no one from the department was familiar enough with e-sports to discuss the topic. Game companies say it is too early to predict how university administrations will become involved in e-sports. “This is just how basketball was in the 1940s,” says Christopher Wyatt. “A lot of the structure and organization you see in more formal athletics, that groundwork is still being laid down here.” In the meantime, game companies and collegiate league organizers predict that college e-sports could become a pipeline for the growing professional circuit. “We really want e-sports to become as ingrained in the academic environment as anything else," says Tyler Rosen like "speech competitions, football competitions."

Scientists Explain How Moses Parted the Red Sea

Bruce Parker, the former chief scientist of NOAA’s National Ocean Service and currently a visiting professor at the Stevens Institute of Technology, reports at the WSJ that there is a natural explanation for how a temporary path across the Red Sea could have been revealed that that doesn't involve biblical miracles. The explanation involves the tide, a natural phenomenon that would have fit nicely into a well-thought-out plan by Moses, because Moses would have been able to predict when it would happen. In the biblical account, the children of Israel were camped on the western shore of the Gulf of Suez when the dust clouds raised by Pharaoh’s chariots were seen in the distance. The Israelites were now trapped between Pharaoh’s army and the Red Sea. The dust clouds, however, were probably an important sign for Moses; they would have let him calculate how soon Pharaoh’s army would arrive at the coast. Moses had lived in the nearby wilderness in his early years, and he knew where caravans crossed the Red Sea at low tide. He knew the night sky and the ancient methods of predicting the tide, based on where the moon was overhead and how full it was. Pharaoh and his advisers, by contrast, lived along the Nile River, which is connected to the almost tideless Mediterranean Sea. They probably had little knowledge of the tides of the Red Sea and how dangerous they could be

Interestingly enough Moses was not the only leader to cross the Gulf of Suez at low tide. In 1798, Napoleon Bonaparte and a small group of soldiers on horseback crossed the Gulf of Suez, the northern end of the Red Sea, roughly where Moses and the Israelites are said to have crossed. On a mile-long expanse of dry sea bottom exposed at low water, the tide suddenly rushed in, almost drowning them. When Napoleon and his forces almost drowned in 1798 at the northern end of the Gulf of Suez, the water typically rose 5 or 6 feet at high tide (and up to 9 or 10 feet with the wind blowing in the right direction). But there is evidence that the sea level was higher in Moses’ time. As a result, the Gulf of Suez would have extended farther north and had a larger tidal range. If that was indeed the case, the real story of the Israelites’ crossing wouldn’t have needed much exaggeration to include walls of water crashing down on the pursuing Egyptians.

US Braces for Backlash from Torture Report

The NYT reports that with the release of the long-awaited Senate report on the use of torture by the United States government — a detailed account that will shed an unsparing light on the Central Intelligence Agency’s darkest practices after the September 2001 terrorist attacks, the US is bracing itself for the risk that it will set off a backlash overseas. Some leading Republican lawmakers have warned against releasing the report, saying that domestic and foreign intelligence reports indicate that a detailed account of the brutal interrogation methods used by the CIA during the George W. Bush administration could incite unrest and violence, even resulting in the deaths of Americans. The White House acknowledged that the report could pose a “greater risk” to American installations and personnel in countries like Pakistan, Yemen, Egypt, Libya and Iraq. But it said that the government had months to plan for the reverberations from its report — indeed, years — and that those risks should not delay the release of the report by the Senate Intelligence Committee. “When would be a good time to release this report?” the White House press secretary, Josh Earnest, asked. “It’s difficult to imagine one, particularly given the painful details that will be included.”

Among the administration’s concerns is that terrorist groups will exploit the disclosures in the report for propaganda value. The Islamic State already clads its American hostages in orange jumpsuits, like those worn by prisoners in CIA interrogations. Hostages held by the Islamic State in Syria were subjected to waterboarding, one of the practices used by the CIA to extract information from suspected terrorists. The 480-page document reveals the results of Senate investigation into the CIA's use of torture and other techniques that violate international law against prisoners held on terrorism-related charges. Though many details of the Senate's findings will remain classified – the document is a summary of a 6,000-page report that is not being released – the report is expected to conclude that the methods used by the CIA to interrogate prisoners during the post-9/11 years were more extreme than previously admitted and produced no intelligence that could not have been acquired through legal means.

Civil Rights Groups Divided on Net Neutrality

Edward Wyatt reports at the NYT that the NAACP, the National Urban League and the Rainbow/PUSH Coalition have sent representatives, including the Rev. Jesse L. Jackson, to tell Tom Wheeler, chairman of the Federal Communications Commission, that they think Obama’s call to regulate broadband Internet service as a utility would harm minority communities by stifling investment in underserved areas and entrenching already dominant Internet companies. Jackson "was unequivocal in voicing his opposition to Title II because of its effects on investment in broadband and because of the ultimate impact on minority communities and job creation," says Berin Szoka, another participant in the meeting with Wheeler who has also argued for Section 706. "We got a lot of poor folks who don't have broadband," said Jackson. "If you create something where, for the poor, the lane is slower and the cost is more, you can't survive." “I think we’re all on board with the values embedded in what President Obama said, things like accelerating broadband deployment and adoption,” says Nicol Turner-Lee, vice president of the Minority Media and Telecommunications Council and a member of the group including Mr. Jackson that met with the F.C.C. chairman. “The question is, will we be able to solve these issues by going so far with stringent regulation?”

Some of the groups that oppose Title II designation, like the Urban League and the League of United Latin American Citizens, have received contributions from organizations affiliated with Internet service providers, like the Comcast Foundation, the charitable organization endowed by Comcast. But those organizations say that the donations or sponsorships do not influence their positions. “We get support from people on all sides of the issue, including Google and Facebook,” says Brent A. Wilkes, national executive director of the League of United Latin American Citizens. “We don’t let any of them influence our position.” For it's part, the NAACP says its formal policy position is that the NAACP neither endorses, nor opposes the formally defined concept of net neutrality but supports the need to particularly focus on underserved racial and ethnic minority and poor communities, while highlighting the importance of protecting an open internet.

French Publishers Prepare Lawsuit Against Adblock Plus

Frédéric Filloux reports at Monday Note that two groups of French publishers, the GESTE and the French Internet Advertising Bureau, are considering a lawsuit against AdBlockPlus creator Eyeo GmbH on grounds that it represents a major economic threat to their business. According to LesEchos.fr, EYEO, which publishes Adblock Plus, has developed a business model where they offer not to block publishers' advertisements for remuneration as long as the ads are judged non-intrusive (Google Translate, Original here). "Several criteria must be met as well: advertisements must be identified as such, be static and therefore not contain animation, no sound, and should not interfere with the content. A position that some media have likened to extortion."

According to Filloux the legal action misses the point. By downloading AdBlock Plus (ABP) on a massive scale, users are voting with their mice against the growing invasiveness of digital advertising. Therefore, suing Eyeo, the company that maintains ABP, is like using Aspirin to fight cancer. A different approach is required but very few seem ready to face that fact. "We must admit that Eyeo GmbH is filling a vacuum created by the incompetence and sloppiness of the advertising community’s, namely creative agencies, media buyers and organizations that are supposed to coordinate the whole ecosystem," says Filloux. Even Google has begun to realize that the explosion of questionable advertising formats has become a problem and the proof is Google's recent Contributor program that proposes ad-free navigation in exchange for a fee ranging from $1 to $3 per month. "The growing rejection of advertising AdBlock Plus is built upon is indeed a threat to the ecosystem and it needs to be addressed decisively. For example, by bringing at the same table publishers and advertisers to meet and design ways to clean up the ad mess. But the entity and leaders who can do the job have yet to be found."

New Simulations Counter Black Hole Illusion

Spatial disorientation (SD) is the leading aeromedical cause of Class A mishaps not only throughout DoD aviation, but in commercial flying as well including problems coping with the Black Hole Illusion, or BHI – when a pilot on a nighttime runway approach in a poorly lit area perceives he is higher than he should be and descends to a lower approach. So what causes this visual illusion? Perception scientists don’t exactly know for sure. There is disagreement as to the exact cause and probably no one theory alone fully explains the phenomenon. Across the services, SD related mishaps result in average annual losses of 25 lives and $400 million in aircraft. Now Bryant Jordan reports from Defense Tech that researchers have developed new simulation and training programs to help all Defense Department pilots avoid BHI and another potentially fatal spatial misperception. The unit tested a team of 38 pilots in day– and nighttime simulation landings, finding that they all flew near perfect approaching in the daylight. But 92 percent made “significantly low BHI approaches” in the nighttime simulation, the report said. On average, they were 148 feet too low when 1.5 nautical miles from the runaway, it said. “If unlit high terrain or obstacles are near the approach path the results can be fatal,” says Henry P. Williams, a researcher with the Naval Medical Research Unit-Dayton. After BHI training pilots were, on average, just three feet too low at the same distance from the runway.

Another spatial disorientation problem tackled in the same study was Control Reversal Error, or CRE, which occurs when pilots lose visuals on a lead aircraft while making turns – as will happen flying into clouds. When that happens pilots swap over to instrument control to recover from the turn, but in nearly a quarter of the cases pilots turned in the wrong direction and steepened the angle of bank (PDF), researchers found. "This error can be extremely dangerous in actual instrument flight, leading to incapacitating [spatial disorientation] and a fatal departure from controlled flight."

Twitter Use by Romney and Obama in the 2012 Elections

On 30 August 2012, Hollywood star Clint Eastwood took the stage to lambast President Obama. What ensued was an odd, 11-minute monologue where Eastwood conversed with an empty chair upon which an imaginary Barack Obama sat. The evening of Eastwood’s speech the official campaign Twitter account @MittRomney did not mention the actor, while the Obama campaign deftly tweeted out from @BarackObama a picture of the president sitting in his chair with the words “This Seat’s Taken”. The picture was retweeted 59,663 times, favorited 23,887 times, and, as importantly, was featured in news articles across the country. According to Daniel Kress both campaigns sought to influence journalists in direct and indirect ways, and planned their strategic communication efforts around political events such as debates well in advance. Despite these similarities, staffers say that Obama’s campaign had much greater ability to respond in real time to unfolding commentary around political events (PDF) given an organizational structure that provided digital staffers with a high degree of autonomy.

Romney's social media team did well when it practiced its strategy carefully before big events like the debates. But Obama's social media team was often quicker to respond to things and more creative. According to Kress, at extraordinary moments campaigns can exercise what Isaac Reed calls “performative power,” influence over other actors’ definitions of the situation and their consequent actions through well-timed, resonant, and rhetorically effective communicative action and interaction. During the Romney campaign as many as 22 staffers screened posts for Romeny's social media accounts before they could go out. As Romney’s digital director Zac Moffatt told Kreiss, the campaign had “the best tweets ever written by 17 people. ... It was the best they all could agree on every single time.”
