1 . Heads or Tails?

Careful: It’s not 50-50

The phrase “coin toss” is a classic synonym for randomness. But since the 18th century, mathematicians have _________ that even fair coins tend to land on one side slightly more often than the other. Proving this tiny bias, _________, would require hundreds of thousands of carefully recorded coin flips, making laboratory tests a logistical (后勤的，组织协调的) _________.

František Bartoš, currently a Ph.D. candidate studying the research methods of psychology at the University of Amsterdam, became interested in this _________ four years ago. He couldn’t _________ enough volunteers to investigate it at first. But after he began his Ph.D. studies, he tried again, recruiting 47 volunteers from six countries. Multiple weekends of coin flipping later, including one 12-hour marathon _________, the team performed 350,757 tosses, breaking the previous record of 40,000.

With one side initially upward, the flipped coin landed with the same side facing _________ as before the toss 50.8 percent of the time. The large number of throws allows _________ to conclude that the nearly 1 percent bias isn’t a fluke (侥幸). “We can be quite sure there is a bias in coin flips after this data set,” Bartoš says.

The leading theory explaining the _________ advantage comes from a 2007 physics study by Stanford University statisticians, whose calculations predicted a same-side bias of 51 percent. From the moment a coin is launched into the air, its entire track — including whether it lands on heads or tails — can be calculated by the laws of __________. The researchers determined that airborne coins don’t turn around their symmetrical axis (对称轴); __________, they tend to move off-center, which causes them to spend a little more time high in the air with their initial “up” side on top.

For day-to-day decisions, coin tosses are as good as random because a 1 percent bias isn’t __________ with just a few coin flips, says statistician Ameli, who wasn’t involved in the new research. Still, the study’s conclusions should eliminate any lasting doubt regarding the coin flip’s slight bias. “This is great experiment-based evidence __________ the bias,” she says.

It isn’t difficult to prevent this bias from influencing your coin-toss matches; simply __________ the coin’s starting position before flipping it should do the trick. But if your friends are __________ the tiny bias, you may as well benefit from your slight advantage. After all, 51 percent odds beat a casino’s house advantage. “If you asked me to bet on a coin,” Bartoš says, “why wouldn’t I give myself a 1 percent bias?”

2 . “Blame My Brain” by Nicola Morgan, reviewed by Rosalie Warren

As someone who constantly blames my brain for all sorts of things (not my fault — my brain did it!), I was _______ by the title of Nicola Morgan’s book and only slightly disappointed to learn that it was _______ teenagers. Since I have many days when I feel that I am barely out of my teens (though the mirror, sadly, does not bear this out), I decided that the book might still be relevant to me, and indeed to my relationships with my no-longer-teenage children.

The subtitle is “The amazing teenage brain revealed” and amazing is, I soon _______, exactly what the teenage brain is. I learned that one of the things that _______ to the brain in our early teenage years is a flurry of growth of the dendrites (connections between neurons), followed a few years later by a major pruning session where many of the relatively unused connections are culled and the remaining ones are strengthened and coated with a fatty myelin layer ready for adult life. Not _______, all this activity is not without its downside for the person “within”, and it goes along way towards _______ why teenagers can be so difficult to live with and to cope with themselves.

There are also brain-based explanations of why teenagers need so much sleep, why they don’t tidy their rooms, why they come _______ when the rest of the world is going to sleep and why some of them, at least, are risk-takers. There’s stuff about alcohol and drugs and why such things are not good for the brain, but all of it is written in a very _______ and understanding way that I think teenagers will warm to.

Nicola Morgan is not a neurologist or a _______ scientist, but she clearly had done a great deal of research and ________ experts including Professor Simon Baron-Cohen and Professor Susan Greenfield, among many other eminent names in the field. Morgan has a gift for simplifying and explaining ________ subject matter with a light but precise touch, and she is careful to ________ between established facts and theories and speculations of her own and other people’s.

There’s plenty of humour and a good few well-deserved digs at the stupidity of parents and other well-meaning but misguided adults, which teenagers will ________. There are diagrams, tests, photos relating to questions like What emotions can you recognize? Do you ________ other emotions with anger? What kind of thinker are you? Which mental tasks do you find comparatively easy or difficult? There’s also sound advice for addiction, self-harm, depression and other ________ illnesses, and some pointers towards recognizing when you may need to seek help.

The illustrations by Andy Baker are great, too. And oh yes — there’s some interesting discussion on the differences between girls’ brains and boys’, if there are any. You’ll have to read it to find out...

3 . History has not yet _______ what we will definitively call the postmillennial cohort (2000年后出生的人) that now _______ more than 60 million people in the U.S. These kids and _______ with no concept of life _______ the Internet have so far been called the App Generation and Generation Z. They’ve been referred to as Homelanders, having grown up under the ghost of terorism. They’ve also been _______ the Plurals, for their historic diversity, as well as the Founders, at least by MTV.

Whatever we _______ naming them, marketers and academies are turning their attention to this group, which has billions in _______ and is already shaping the culture. This generation is growing up “totally and utterly connected,” says California State University psychologist Larry Rosen. Experts like Rosen have concerns about these kids’ Google-inspired expectations that everything be _______. They worry about their inability to _______ even five seconds of boredom. And they worry about the demands that come with ________ several identities online, from Facebook to Twitter to Snapchat. “There’s so much pressure on young people, who are still ________ their identities, to present this crystallized, idealized identity online,” says the University of Washington’s Katie Davis.

Historian Neil Howe sees ________ with the Silent Generation, the spoilt, risk-avoiding, “nice” generation of kids who grew up during the Great Depression and World War II, although some marked differences are found. Today’s youths are also coming of age among geopolitical trouble and fears about the economy, he says, ________ schools emphasize an intense far-reaching sensitivity to other kids. He suspects this ________ will be known for being well behaved and perhaps boring the culture by playing it safe. “There are typical examples that occur repeatedly,” Howe says, “even if they go by different ________.”

4 . Facing AI extinction

In a recent White House press conference, press secretary Karine Jean-Pierre couldn’t suppress her laughter at the question: Is it “crazy” to worry that “literally everyone on Earth will die” due to artificial intelligence? _________, the answer is no.

While AI pioneer such as Alan Turing cautioned that we should expect “machines to take control”, many contemporary researchers _________ this concern. In an area of unprecedented growth in AI abilities, why aren’t more expects weighing in?

Before the deep-learning revolution in 2012, I didn’t think human-level AI would emerge in my lifetime. I was familiar with arguments that AI systems would insatiably seek power and resist shutdown — and obvious _________ to humanity if it were to occur. But I also figured researchers must have good reasons not to be worried about human _________ risk (x-risk) from AI.

Yet after 10 years in the field, I believe the main reasons are actually cultural and historical. By 2012, after several hype cycles that didn’t pan out, most AI researchers had stopped asking ‘what if we succeed at replicating human intelligence’, _________ their ambitions to specific tasks like autonomous driving.

When concerns resurfaced outside their community, researchers were to quick to dismiss outsiders as _________ and their worries as science fiction. But in my experience, AI researchers are themselves often ignorant of arguments for AI x-risk.

One basic argument is by analogy: humans’ _________ abilities allowed us to out-compete other species for resources, leading to many extinctions. AI systems could likewise deprive us of the resources we need for our survival. Less _________, AI could displace humans economically and, through its powers of manipulation, politically.

But wouldn’t it be humans wielding AIs as tools who end up in control? Not necessarily. Many people might choose to deploy a system with a 99 per cent chance of making them phenomenally rich and powerful, even if it had a 1 per cent chance of _________ their control and killing everyone.

Because no safe experiment can definitively tell us whether an AI system will actually kill everyone, such concerns are often dismissed as unscientific. But this isn’t an excuse for ignoring the risk. It just means society needs to reason about it in the same way as other complex social issues. Researchers also emphasize the difficulty of predicting when AI might _________ human intelligence, but this is an argument for caution, not complacency.

Attitudes are changing, but not quickly enough. AI x-risk is admittedly more _________ than important social issues with present-day AI, like bias and misinformation, but the basic solution is the same: regulation. A robust public discussion is long overdue. By refusing to engage, some AI researchers are neglecting _________ responsibilities and betraying public trust.

Big tech sponsors AI ethics research when it doesn’t hurt the bottom line. But it is also lobbying to exclude general-purpose AI from E. U. regulation. Concerned researchers recently called for a(n) _________ in developing bigger AI models to allow society to catch up. Critics say this isn’t politically realistic, but problems like AI x-risk won’t _________ just because they are politically inconvenient.

This brings us to the ugliest reason researchers may dismiss AI x-risk: funding. Essentially every researcher (myself included) has received funding from big tech. At some point, society may stop believing reassurances from people with such strong conflicts of _________ and conclude, as I have, that their dismissal betrays wishful thinking rather than good counterarguments.

5 . To prevent tsunami-caused disasters, several countries worked together to expand the use of a tsunami-detecting system that had been developed in the United States by the National Oceanic and Atmospheric Administration (NOAA). The system________ of an instrument installed on the seafloor — called a tsunameter — that measures pressure changes caused by a passing tsunami. The tsunameter sends a signal to a surface buoy (浮标), which sends the data to a satellite, which ________ the information to warning centers around the world.

By 2004 only six such detectors had been installed, all in the Pacific. There were________ in the Indian Ocean, and many countries in the region had no national warning centers that could have ________ local communities. That policy mistake had tragic consequences. In Sumatra people had only a few minutes to run, ________the tsunami took two hours to reach India, and some 16,000 people died there. “It was totally unnecessary,” says Paramesh Banerjee, a geo-physicist at Nanyang Technological University in Singapore. “Technically it would have been relatively ________ to install a tsunami warning system for the Indian Ocean.”

There are now 53 detector buoys operating in the world’s oceans, including 6 of a planned 27 in the Indian Ocean. So a (n)________ of the 2004 horror, in which the tsunami traveled for hours and still caught people by ________ is less likely. But buoys would not have helped in Sumatra. People living on coasts near a rupturing fault (地壳断层) can’t wait for ________ that a tsunami is on its way, which it often isn’t; they must flee as soon as the quake hits. The Japanese warning system relies not only on tsunameters but also on seismometers (地震测量仪) — a thousand of them ________ the country, the densest network anywhere — combined with a computer model that forecasts the scale of a tsunami from the magnitude (震级) and ________ of the quake.

In March, the system, which is run by the Japan Meteorological Agency (JMA), did not work perfectly. JMA’s initial ________, while the ground was still shaking, put the quake magnitude at 7.9 — but later analysis revealed a quake that, at magnitude 9, was 12 times larger. The tsunami forecast warned of waves of ten feet or more — but they reached 50 feet in Minanisanriku and in some places even ________. But the human ________ to the warning was imperfect as well. “I think this time many people who lived above the high-water mark of the 1960 tsunami didn’t bother to run.” says Jin Sato, mayor of Minanisanriku. “Many of them died.” The town’s seawall, he thinks, also gave people a false sense of ________

6 . It started with a bit of casual discomfort on the head, but after a week it had spread to the back of my neck, enough to lead me to my laptop. Annoying as it was, I was ________ to take up my doctor’s time with such a silly complaint and then have a wasted journey only to be informed that it would clear up by itself and that ________ would be of no use at all.

As soon as I’d tapped in ‘online self-diagnosis’, the search engine provided me with over 11.5 million results. And during the time normally spent in the clinic’s waiting room reading the Women’s Weekly, I was able to find a site that would provide a free ________ in the comfort of my chair, and with no need for an appointment,

I answered all the questions until I eventually reached a description exactly matching my ________. As I clicked on ‘More Information’, I was hit with what I’d never anticipated. The worst case scenario was complete hair loss. I couldn’t have been more ________.

I headed off to the doctor for what I thought would be a blood test but which turned out to be a valuable lesson in not ________ everything you read on the internet. It took him less than a minute to guess at and locate head lice (虱子). I was relieved to know that I would be ________ my hair, and horrified to know that it was being occupied.

I learnt my lesson, but for some the worry caused by ________ every ache has led to a new form of hypochondria (疑病症). Named ‘cyberchondria’ by the print media back in 2000, this particular condition has ________ greatly. Although most people’s main point of call is still the doctor’s surgery, it’s estimated that ________ worries are now the second most researched topic on the web. This is truly a serious concern when about 25%of the medical information online is thought to be ________.

Once upon a time, hypochondria required time and effort: you had to go to the library to research your diseases and ________ go through the books. Now it’s just a matter of a few clicks of a mouse. But while your doctor will make a diagnosis ________ your age, appearance and medical history, a search engine will rely simply on algorithms (算法). These come up with results graded according to popularity or numbers of key words. So the most highly ranked hits might actually be for very genuine disease, which are nonetheless extremely ________. One minute you think you’ve come down with the flu, the next you’re under attack from sub-tropical, flesh-eating bacteria. Time spent going to the doctor’s for ________ of mind suddenly seems fair enough.

7 . The Great PowerPoint Panic of 2003.

Sixteen minutes before touchdown on the morning of February 1, 2003, the space shuttle Columbia (“哥伦比亚”号航天飞机)______ into the cloudless East Texas sky. All seven astronauts aboard were killed. As the shattered shuttle flew toward Earth in pieces, it looked to its live TV viewers like a swarm of shooting stars.

The immediate ______ of the disaster, a report from a NASA Accident Investigation Board determined that August, was a piece of insulating foam (绝缘泡沫胶) that had broken loose and damaged the shuttle’s left wing soon after liftoff. But the report also   ______ out a less direct, more surprising cause. Engineers had known about - and inappropriately______ - the wing damage long before Columbia’s attempted reentry, but the flaws in their analysis were ______ in a series of overstuffed computer-presentation slides that were shown to NASA officials.

By the start of 2003, the phrase “death by PowerPoint” had well and truly entered the ______ vocabulary. Edward Tufte was the first to have taken it literally: That spring, the Yale statistician published a booklet entitled The Cognitive Style of PowerPoint, whose core argument was that the medium of communication influences the substance of communication. While PowerPoint, as a medium, did not ______ create unclear, lazy presentations, it certainly ______ and sometimes even masked them — with potentially deadly consequences. This is exactly what Tufte saw in the Columbia engineers’ slides.

Wired ran an excerpt (节选) from Tufte’s booklet in September 2003 under the headline “PowerPoint Is Evil.” A few months later, The New York Times Magazine included his assessment — summarized as “PowerPoint Makes You Dumb” — in its ______ of the year’s most important ideas. “Perhaps PowerPoint is uniquely suited to our modern age of confusion,” the entry read.

Despite the backlash it inspired in the ______, the presentation giant rolls on. The program has more monthly users than ever before, well into the hundreds of millions. During lockdown, people ______ PowerPoint parties on Zoom. Kids now make PowerPoint presentations for their parents when they want to get a puppy. If PowerPoint is evil, then evil ______ the world.

On its face at least, the idea that PowerPoint makes us stupid looks like a textbook case of misguided technological doomsaying. Today’s concerns about social media somehow resemble the PowerPoint critique. Both boil down to a worry that new media technologies ______ form over substance, that they are designed to hold our attention rather than to convey truth, and that they make us stupid.

______, concerns about new media rarely seem to make a difference. If the innovation did change the way we think, we are measuring its effects with an altered mind. Either the critical remarks were wrong, or they were so right that we can no longer tell the   ______.

8 . At first, the grains of rice that Ingo Potrykus held in his fingers did not seem at all _________, but inside, these grains were not white, as ordinary rice is, but a very pale yellow — thanks to beta-carotene (胡萝卜素), a building block for vitamin A.

For more than a decade Potrykus had _________ creating a golden rice that could improve the lives of millions of the poorest people in the world, strengthening their eyesight and their _________ disease.

_________ imagining golden rice was one thing and creating one quite another. Year after year, Potrykus and his colleagues ran into one _________ after another until success finally came in the spring of 1999.

At that point, he tackled an even greater challenge. The golden grains _________ pieces of DNA borrowed from bacteria and flowers. It was what some would call Frankenfood, a product of genetic engineering. As such, it _________ a web of hopes and fears.

The debate began the moment genetically engineered crops (GM crops) were first sold in the 1990s, and it has _________ ever since. First to start major protests against biotechnology were European environmentalists and consumer-advocacy groups. They were soon followed by their U.S. counterparts (相对应的人事物).

The hostility is _________. Most of the GM crops __________ so far have been developed to produce a plant that is not harmed by chemicals used to kill weeds (杂草) in the fields. These genetically engineered crops are often sold by the same large, multinational corporations that __________ the weed-killing chemicals that farmers spray on their fields. Consumers have become suspicious (怀疑的).

The benefits did seem small __________ golden rice was developed. It is the first strong example of a GM crop that may __________ not just the farmers who grow it but also the consumers who eat it. In this case, those include at least a million children who die every year because they are weakened by vitamin-A deficiency (缺乏) and an additional 350,000 who go blind.

Many people __________ poverty and hunger look at golden rice and see it as evidence that GM crops can be made to serve the greater public good. They see a critical role for GM crops in feeding the world’s ever-increasing population. As former U.S. President Jimmy Carter put it, “Responsible biotechnology is not the enemy; __________ is.”

9 . Background noise—like the chatter in a coffee shop or the drone of passing traffic—might slow our reading speed, but according to a study of Russian readers, it doesn’t _________ how our brain understands written text.

_________, if you’re wondering whether you should be listening to podcasts or music while working, the study has some interesting points to make. In particular, it examined how we might change our reading style to compensate for auditory noise and visual distractions such as typos or poor formatting.

“Overall, previous studies reported a harmful effect of both auditory and visual noise on reading fluency and _________, though their results varied,” write linguistics researcher Nina Zdorova and colleagues. “So far, none of the studies exploring the influence of noise _________ it in the framework of the language processing theories.”

One of the language processing theories examined was the noisy channel model, which proposes that our brain deals with noise by looking at the meaning of _________ words more and at entire sentences less. We then use a bit of smart guesswork to _________ the overall meaning and relationships between words.

The second theory is the good enough model; that’s when our brains aren’t analyzing every single detail of a text but instead only grabbing enough words for a ‘good enough’ understanding. By focusing less on the precise words, our brains can _________ some cognitive resources to deal with noise.

To see how reading was affected by noise _________ these models, the researchers ran two experiments: one on auditory noise (71 participants) and one on visual noise (70 participants). When it came to the auditory noise test, background chatter from overlapping podcasts caused people to spend longer looking at the key section of sentences before completing their reading. This extra time could _________ the noise, meaning sentence comprehension isn’t affected by it. In the visual noise test, comprehension remained the same while reading speed __________. That’s a bit __________ considering previous studies, but the researchers think people just wanted to finish the task, with the visual noise an uncomfortable distraction.

“In both experiments, we observed that longer total reading time was __________ with an accuracy increase for incorrect sentences,” write the researchers.

There’s a lot going on in this study, but overall it’s a bigger win for the good-enough language processing theory and an indication that auditory and visual noise doesn’t make us __________ any more or less on any particular comprehension method while we’re reading.

With so many variables to measure in terms of what’s being read and what the __________ noise is, further study is required to learn more. __________ potential distractions may not interrupt your reading as much as you think.

10 . Scientific discovery is popularly believed to result from the sheer genius of such intellectual stars as naturalist Charles Darwin and theoretical physicist Albert Einstein. Our view of such unique contributions to science often _________ the person’s prior experience and the efforts of their lesser-known predecessors (前任者).

_________ such greats as Darwin and Einstein—whose remarkable contributions are duly celebrated — we suggest that innovation is more a process of trial and error, where two steps forward may sometimes come with one step back, as well as one or more steps to the right or left. This evolutionary view of human innovation weakens the idea of _________ genius and recognizes the accumulative nature of scientific progress.

Consider one _________ scientist: John Nicholson, a mathematical physicist working in the 1910s who assumed the existence of ‘proto-elements’ in outer space. By combining different numbers of weights of these proto-elements’ atoms, Nicholson could recover the weights of all the elements in the then-known periodic table. These successes are all the more noteworthy given the fact that Nicholson was _________ about the presence of proto-elements: they do not actually exist. Yet, amid his often fanciful theories and wild guesses, Nicholson also _________ a new theory about the structure of atoms. Niels Bohr, the Nobel prize-winning father of modern atomic theory, _________ this interesting idea to come up with his now-famous model of the atom.

What are we to make of this story? We propose that science is constantly _________, much as species of animals do. In biological systems, organisms may display new characteristics that _________ random genetic mutations (变异). In the same way, random or accidental mutations of ideas may help pave the way for __________ in science. __________ mutations prove beneficial, the animal or the scientific theory will continue to thrive and perhaps reproduce.

__________ for this evolutionary view of behavioral innovation comes from many domains. Consider one example of an influential innovation in US horseracing. The so-called ‘acey-deucy’ stirrup (马镫) placement, in which the rider’s foot in his left stirrup is placed as much as 25 centimeters lower than the right, is believed to give important speed advantages when turning on egg-shaped tracks. It was developed by a relatively unknown jockey named Jackie Westrope. Had he __________ the speed advantage that would be provided by riding acey-deucy? No. He suffered a leg injury, which left him unable to fully bend his left knee. His __________ just happened to coincide with enhanced left-hand turning performance.

Plenty of other stories show that fresh advances can arise from error, misadventure, and also pure serendipity — a happy __________. The time seems right for abandoning the naive notions of intelligent design and genius, and for scientifically exploring the true origins of creative behavior.
