Edward Sapir, one of the most influential American linguists, wrote: “The worlds in which different societies live are distinct worlds, not merely the same worlds with different labels attached” (Sapir, 1949: 162).

Now it was suggested that the world might be perceived differently by people speaking different languages.

This effect of framing or filtering is the main effect we can expect—regarding language—from perception and thought. Languages do not limit our ability to perceive the world or to think about the world, but they focus our perception, attention, and thought on specific aspects of the world.

Chinese-speaking children learn to count earlier than English-speaking children because Chinese numbers are more regular and transparent than English numbers (in Chinese, "eleven" is "ten one").

So, different languages focus the attention of their speakers on different aspects of the environment—either physical or cultural.

We linguists say that these salient aspects are either lexicalized or grammaticalised. Lexicalizing means that you have words for concepts, which work as shorthands for those concepts. This is useful because you don't need to explain (or paraphrase) the meaning you want to convey.

The lexicon is like a big, open bag: Some words are coined or borrowed because you need them for referring to new objects, and they are put into the bag. Conversely, some objects are not used anymore, and then the words for them are removed from the bag.

Dyirbal, a language spoken in Northern Australia, for example, has four noun classes (like English genders).

This grammatical classification of nouns involves a coherent view of the world, including an original mythology.

In summary, language functions as a filter of perception, memory, and attention. Whenever we construct or interpret a linguistic statement, we need to focus on specific aspects of the situation that the statement describes

found, using virtual reality, that people differ in how much they are influenced by their visual environment

"These findings may also help us to better understand and predict why astronauts may misestimate how far they have moved in a given situation, especially in the microgravity of space," says Harris.

Not only did the VRI-vulnerable group rely more on vision to tell them how they were oriented, but they also found visual motion to be more powerful in evoking the sensation of moving through the scene,

This decision is helped by the fact that we normally move at right angles to gravity.

But if a person's perception of gravity is altered by the visual environment or by removing gravity, this distinction becomes much harder."

The findings could also be helpful for virtual reality game designers, as certain virtual environments may lead to differences in how players interpret and move through the game.

“For many of us, we’d literally rather not know because otherwise it creates such an acutely distressing experience for us as humans.”

this inability to engage presents itself as a complete denial of the climate crisis and climate science. But even among those who accept the dire predictions for the natural world, there are “micro-denials” that can block the ability to take action.

“In an individual person, the contributions of genes and the environment are inestimable,” she explained, “but on a population basis we can estimate how much person-to-person variation is explained by genetic and environmental differences.”

No, says the other camp, led by Jonathan Haidt; the kids are not all right, their devices are partly to blame, and here are the studies showing why.

we should not wait for the replication crisis in the social sciences to resolve itself before we consider the question of whether the naysayers are on to something. And normal powers of observation and imagination should be sufficient to make us at least wary of smartphones.

These powerful instruments represent a technological advance on par with that of the power loom or the automobile

The achievement can be difficult to properly appreciate because instead of exerting power over physical processes and raw materials, they operate on social processes and the human psyche: They are designed to maximize attention, to make it as difficult as possible to look away.

they have transformed the qualitative experience of existing in the world. They give a person’s sociality the appearance and feeling of a theoretically endless open network, while in reality, algorithms quietly sort users into ideological, aesthetic, memetic cattle chutes of content.

Importantly, the process by which smartphones change us requires no agency or judgment on the part of a teen user, and yet that process is designed to provide what feels like a perfectly natural, inevitable, and complete experience of the world.

Smartphones offer a tactile portal to a novel digital environment, and this environment is not the kind of space you enter and leave

One reason commonly offered for maintaining our socio-technological status quo is that nothing really has changed with the advent of the internet, of Instagram, of Tiktok and Youtube and 4Chan

It is instead a complete shadow world of endless images; disembodied, manipulable personas; and the ever-present gaze of others. It lives in your pocket and in your mind.

The price you pay for its availability—and the engine of its functioning—is that you are always available to it, as well. Unless you have a strength of will that eludes most adults, its emissaries can find you at any hour and in any place to issue your summons to the grim pleasure palace.

the self-restraint and self-discipline required to use a smartphone well—that is, to treat it purely as an occasional tool rather than as a totalizing way of life—are unreasonable things to demand of teenagers

these are unreasonable things to demand of me, a fully adult woman

To enjoy the conveniences that a smartphone offers, I must struggle against the lure of the permanent scroll, the notification, the urge to fix my eyes on the circle of light and keep them fixed. I must resist the default pseudo-activity the smartphone always calls its user back to, if I want to have any hope of filling the moments of my day with the real activity I believe is actually valuable.

for a child or teen still learning the rudiments of self-control, still learning what is valuable and fulfilling, still learning how to prioritize what is good over the impulse of the moment, it is an absurd bar to be asked to clear

The expectation that children and adolescents will navigate new technologies with fully formed and muscular capacities for reason and responsibility often seems to go along with a larger abdication of responsibility on the part of the adults involved.

adults have frequently given in to a Faustian temptation: offering up their children’s generation to be used as guinea pigs in a mass longitudinal study in exchange for a bit more room to breathe in their own undeniably difficult roles as educators, caretakers, and parents.

It is not a particular activity that you start and stop and resume, and it is not a social scene that you might abandon when it suits you.

And this we must do without waiting for social science to hand us a comprehensive mandate it is fundamentally unable to provide; without cowering in panic over moral panics

The pre-internet advertising world was vicious, to be sure, but when the “pre-” came off, its vices were moved into a compound interest account. In the world of online advertising, at any moment, in any place, a user engaged in an infinite scroll might be presented with native content about how one Instagram model learned to accept her chunky (size 4) thighs, while in the next clip, another model relates how a local dermatologist saved her from becoming an unlovable crone at the age of 25

developing pathological interests and capacities used to take a lot more work than it does now

You had to seek it out, as you once had to seek out pornography and look someone in the eye while paying for it. You were not funneled into it by an omnipresent stream of algorithmically curated content—the ambience of digital life, so easily mistaken by the person experiencing it as fundamentally similar to the non-purposive ambience of the natural world.

And when interpersonal relations between teens become sour, nasty, or abusive, as they often do and always have, the unbalancing effects of transposing social life to the internet become quite clear

For both young men and young women, the pornographic scenario—dominance and degradation, exposure and monetization—creates an experiential framework for desires that they are barely experienced enough to understand.

This is not a world I want to live in. I think it hurts everyone; but I especially think it hurts those young enough to receive it as a natural state of affairs rather than as a profound innovation.

so I am baffled by the most routine objection to any blaming of smartphones for our society-wide implosion of teenagers’ mental health,

In short, and inevitably, today’s teenagers are suffering from capitalism—specifically “late capitalism,

what shocks me about this rhetorical approach is the rush to play defense for Apple and its peers, the impulse to wield the abstract concept of capitalism as a shield for actually existing, extremely powerful, demonstrably ruthless capitalist actors.

This motley alliance of left-coded theory about the evils of business and right-coded praxis in defense of a particular evil business can be explained, I think, by a deeper desire than overthrowing capitalism. It is the desire not to be a prude or hysteric of bumpkin

No one wants to come down on the side of tamping off pleasures and suppressing teen activity.

No one wants to be the shrill or leaden antagonist of a thousand beloved movies, inciting moral panics, scheming about how to stop the youths from dancing on Sunday.

But commercial pioneers are only just beginning to explore new frontiers in the profit-driven, smartphone-enabled weaponization of our own pleasures against us

To limit your moral imagination to the archetypes of the fun-loving rebel versus the stodgy enforcers in response to this emerging reality is to choose to navigate it with blinders on, to be a useful idiot for the robber barons of online life rather than a challenger to the corrupt order they maintain.

The very basic question that needs to be asked with every product rollout and implementation is what technologies enable a good human life?

this question is not, ultimately, the province of social scientists, notwithstanding how useful their work may be on the narrower questions involved. It is the free privilege, it is the heavy burden, for all of us, to think—to deliberate and make judgments about human good, about what kind of world we want to live in, and to take action according to that thought.

I am not sure how to build a world in which childrens and adolescents, at least, do not feel they need to live their whole lives online.

whatever particular solutions emerge from our negotiations with each other and our reckonings with the force of cultural momentum, they will remain unavailable until we give ourselves permission to set the terms of our common life.

But the environments in which humans find themselves vary significantly, and in ways that have equally significant downstream effects on the particular expression of human nature in that context.

most of all, without affording Apple, Facebook, Google, and their ilk the defensive allegiance we should reserve for each other.

we’re networked organisms who move around in shifting surroundings, environments that have the power to transform our thinking

Annie Murphy Paul’s new book, “The Extended Mind,” which exhorts us to use our entire bodies, our surroundings and our relationships to “think outside the brain.”

In 2011, she published “Origins,” which focused on all the ways we are shaped by the environment, before birth and minute to minute thereafter.

“In the nature-nurture dynamic, nurture begins at the time of conception. The food the mother eats, the air she breathes, the water she drinks, the stress or trauma she experiences — all may affect her child for better or worse, over the decades to come.”

the parallel to this latest book is that the boundaries we commonly assume to be fixed are actually squishy. The moment of a child’s birth, her I.Q. scores or fMRI snapshots of what’s going on inside her brain — all are encroached upon and influenced by outside forces.

The complaint — filed last month with the Securities and Exchange Commission and the Department of Justice, as well as the FTC — says thousands of employees still had wide-ranging and poorly tracked internal access to core company software, a situation that for years had led to embarrassing hacks, including the commandeering of accounts held by such high-profile users as Elon Musk and former presidents Barack Obama and Donald Trump.

the whistleblower document alleges the company prioritized user growth over reducing spam, though unwanted content made the user experience worse. Executives stood to win individual bonuses of as much as $10 million tied to increases in daily users, the complaint asserts, and nothing explicitly for cutting spam.

Chief executive Parag Agrawal was “lying” when he tweeted in May that the company was “strongly incentivized to detect and remove as much spam as we possibly can,” the complaint alleges.

Zatko described his decision to go public as an extension of his previous work exposing flaws in specific pieces of software and broader systemic failings in cybersecurity. He was hired at Twitter by former CEO Jack Dorsey in late 2020 after a major hack of the company’s systems.

“I felt ethically bound. This is not a light step to take,” said Zatko, who was fired by Agrawal in January. He declined to discuss what happened at Twitter, except to stand by the formal complaint. Under SEC whistleblower rules, he is entitled to legal protection against retaliation, as well as potential monetary rewards.

“Security and privacy have long been top companywide priorities at Twitter,” said Twitter spokeswoman Rebecca Hahn. She said that Zatko’s allegations appeared to be “riddled with inaccuracies” and that Zatko “now appears to be opportunistically seeking to inflict harm on Twitter, its customers, and its shareholders.” Hahn said that Twitter fired Zatko after 15 months “for poor performance and leadership.” Attorneys for Zatko confirmed he was fired but denied it was for performance or leadership.

A person familiar with Zatko’s tenure said the company investigated Zatko’s security claims during his time there and concluded they were sensationalistic and without merit. Four people familiar with Twitter’s efforts to fight spam said the company deploys extensive manual and automated tools to both measure the extent of spam across the service and reduce it.

Overall, Zatko wrote in a February analysis for the company attached as an exhibit to the SEC complaint, “Twitter is grossly negligent in several areas of information security. If these problems are not corrected, regulators, media and users of the platform will be shocked when they inevitably learn about Twitter’s severe lack of security basics.”

Zatko’s complaint says strong security should have been much more important to Twitter, which holds vast amounts of sensitive personal data about users. Twitter has the email addresses and phone numbers of many public figures, as well as dissidents who communicate over the service at great personal risk.

This month, an ex-Twitter employee was convicted of using his position at the company to spy on Saudi dissidents and government critics, passing their information to a close aide of Crown Prince Mohammed bin Salman in exchange for cash and gifts.

Zatko’s complaint says he believed the Indian government had forced Twitter to put one of its agents on the payroll, with access to user data at a time of intense protests in the country. The complaint said supporting information for that claim has gone to the National Security Division of the Justice Department and the Senate Select Committee on Intelligence. Another person familiar with the matter agreed that the employee was probably an agent.

“Take a tech platform that collects massive amounts of user data, combine it with what appears to be an incredibly weak security infrastructure and infuse it with foreign state actors with an agenda, and you’ve got a recipe for disaster,” Charles E. Grassley (R-Iowa), the top Republican on the Senate Judiciary Committee,

Many government leaders and other trusted voices use Twitter to spread important messages quickly, so a hijacked account could drive panic or violence. In 2013, a captured Associated Press handle falsely tweeted about explosions at the White House, sending the Dow Jones industrial average briefly plunging more than 140 points.

After a teenager managed to hijack the verified accounts of Obama, then-candidate Joe Biden, Musk and others in 2020, Twitter’s chief executive at the time, Jack Dorsey, asked Zatko to join him, saying that he could help the world by fixing Twitter’s security and improving the public conversation, Zatko asserts in the complaint.

In 1998, Zatko had testified to Congress that the internet was so fragile that he and others could take it down with a half-hour of concentrated effort. He later served as the head of cyber grants at the Defense Advanced Research Projects Agency, the Pentagon innovation unit that had backed the internet’s invention.

But at Twitter Zatko encountered problems more widespread than he realized and leadership that didn’t act on his concerns, according to the complaint.

Twitter’s difficulties with weak security stretches back more than a decade before Zatko’s arrival at the company in November 2020. In a pair of 2009 incidents, hackers gained administrative control of the social network, allowing them to reset passwords and access user data. In the first, beginning around January of that year, hackers sent tweets from the accounts of high-profile users, including Fox News and Obama.

Several months later, a hacker was able to guess an employee’s administrative password after gaining access to similar passwords in their personal email account. That hacker was able to reset at least one user’s password and obtain private information about any Twitter user.

Twitter continued to suffer high-profile hacks and security violations, including in 2017, when a contract worker briefly took over Trump’s account, and in the 2020 hack, in which a Florida teen tricked Twitter employees and won access to verified accounts. Twitter then said it put additional safeguards in place.

This year, the Justice Department accused Twitter of asking users for their phone numbers in the name of increased security, then using the numbers for marketing. Twitter agreed to pay a $150 million fine for allegedly breaking the 2011 order, which barred the company from making misrepresentations about the security of personal data.

After Zatko joined the company, he found it had made little progress since the 2011 settlement, the complaint says. The complaint alleges that he was able to reduce the backlog of safety cases, including harassment and threats, from 1 million to 200,000, add staff and push to measure results.

But Zatko saw major gaps in what the company was doing to satisfy its obligations to the FTC, according to the complaint. In Zatko’s interpretation, according to the complaint, the 2011 order required Twitter to implement a Software Development Life Cycle program, a standard process for making sure new code is free of dangerous bugs. The complaint alleges that other employees had been telling the board and the FTC that they were making progress in rolling out that program to Twitter’s systems. But Zatko alleges that he discovered that it had been sent to only a tenth of the company’s projects, and even then treated as optional.

“If all of that is true, I don’t think there’s any doubt that there are order violations,” Vladeck, who is now a Georgetown Law professor, said in an interview. “It is possible that the kinds of problems that Twitter faced eleven years ago are still running through the company.”

The complaint also alleges that Zatko warned the board early in his tenure that overlapping outages in the company’s data centers could leave it unable to correctly restart its servers. That could have left the service down for months, or even have caused all of its data to be lost. That came close to happening in 2021, when an “impending catastrophic” crisis threatened the platform’s survival before engineers were able to save the day, the complaint says, without providing further details.

One current and one former employee recalled that incident, when failures at two Twitter data centers drove concerns that the service could have collapsed for an extended period. “I wondered if the company would exist in a few days,” one of them said.

The current and former employees also agreed with the complaint’s assertion that past reports to various privacy regulators were “misleading at best.”

For example, they said the company implied that it had destroyed all data on users who asked, but the material had spread so widely inside Twitter’s networks, it was impossible to know for sure

As the head of security, Zatko says he also was in charge of a division that investigated users’ complaints about accounts, which meant that he oversaw the removal of some bots, according to the complaint. Spam bots — computer programs that tweet automatically — have long vexed Twitter. Unlike its social media counterparts, Twitter allows users to program bots to be used on its service: For example, the Twitter account @big_ben_clock is programmed to tweet “Bong Bong Bong” every hour in time with Big Ben in London. Twitter also allows people to create accounts without using their real identities, making it harder for the company to distinguish between authentic, duplicate and automated accounts.

In the complaint, Zatko alleges he could not get a straight answer when he sought what he viewed as an important data point: the prevalence of spam and bots across all of Twitter, not just among monetizable users.

Zatko cites a “sensitive source” who said Twitter was afraid to determine that number because it “would harm the image and valuation of the company.” He says the company’s tools for detecting spam are far less robust than implied in various statements.

“Agrawal’s Tweets and Twitter’s previous blog posts misleadingly imply that Twitter employs proactive, sophisticated systems to measure and block spam bots,” the complaint says. “The reality: mostly outdated, unmonitored, simple scripts plus overworked, inefficient, understaffed, and reactive human teams.”

The four people familiar with Twitter’s spam and bot efforts said the engineering and integrity teams run software that samples thousands of tweets per day, and 100 accounts are sampled manually.

Some employees charged with executing the fight agreed that they had been short of staff. One said top executives showed “apathy” toward the issue.

Zatko’s complaint likewise depicts leadership dysfunction, starting with the CEO. Dorsey was largely absent during the pandemic, which made it hard for Zatko to get rulings on who should be in charge of what in areas of overlap and easier for rival executives to avoid collaborating, three current and former employees said.

For example, Zatko would encounter disinformation as part of his mandate to handle complaints, according to the complaint. To that end, he commissioned an outside report that found one of the disinformation teams had unfilled positions, yawning language deficiencies, and a lack of technical tools or the engineers to craft them. The authors said Twitter had no effective means of dealing with consistent spreaders of falsehoods.

Dorsey made little effort to integrate Zatko at the company, according to the three employees as well as two others familiar with the process who spoke on the condition of anonymity to describe sensitive dynamics. In 12 months, Zatko could manage only six one-on-one calls, all less than 30 minutes, with his direct boss Dorsey, who also served as CEO of payments company Square, now known as Block, according to the complaint. Zatko allegedly did almost all of the talking, and Dorsey said perhaps 50 words in the entire year to him. “A couple dozen text messages” rounded out their electronic communication, the complaint alleges.

Faced with such inertia, Zatko asserts that he was unable to solve some of the most serious issues, according to the complaint.

Some 30 percent of company laptops blocked automatic software updates carrying security fixes, and thousands of laptops had complete copies of Twitter’s source code, making them a rich target for hackers, it alleges.

A successful hacker takeover of one of those machines would have been able to sabotage the product with relative ease, because the engineers pushed out changes without being forced to test them first in a simulated environment, current and former employees said.

“It’s near-incredible that for something of that scale there would not be a development test environment separate from production and there would not be a more controlled source-code management process,” said Tony Sager, former chief operating officer at the cyberdefense wing of the National Security Agency, the Information Assurance divisio

Sager is currently senior vice president at the nonprofit Center for Internet Security, where he leads a consensus effort to establish best security practices.

Zatko stopped the material from being presented at the Dec. 9, 2021 meeting, the complaint said. But over his continued objections, Agrawal let it go to the board’s smaller Risk Committee a week later.

“A best practice is that you should only be authorized to see and access what you need to do your job, and nothing else,” said former U.S. chief information security officer Gregory Touhill. “If half the company has access to and can make configuration changes to the production environment, that exposes the company and its customers to significant risk.”

The complaint says Dorsey never encouraged anyone to mislead the board about the shortcomings, but that others deliberately left out bad news.

The complaint says that about half of Twitter’s roughly 7,000 full-time employees had wide access to the company’s internal software and that access was not closely monitored, giving them the ability to tap into sensitive data and alter how the service worked. Three current and former employees agreed that these were issues.

An unnamed executive had prepared a presentation for the new CEO’s first full board meeting, according to the complaint. Zatko’s complaint calls the presentation deeply misleading.

The presentation showed that 92 percent of employee computers had security software installed — without mentioning that those installations determined that a third of the machines were insecure, according to the complaint.

Another graphic implied a downward trend in the number of people with overly broad access, based on the small subset of people who had access to the highest administrative powers, known internally as “God mode.” That number was in the hundreds. But the number of people with broad access to core systems, which Zatko had called out as a big problem after joining, had actually grown slightly and remained in the thousands.

The presentation included only a subset of serious intrusions or other security incidents, from a total Zatko estimated as one per week, and it said that the uncontrolled internal access to core systems was responsible for just 7 percent of incidents, when Zatko calculated the real proportion as 60 percent.

When Dorsey left in November 2021, a difficult situation worsened under Agrawal, who had been responsible for security decisions as chief technology officer before Zatko’s hiring, the complaint says.

Agrawal didn’t respond to requests for comment. In an email to employees after publication of this article, obtained by The Post, he said that privacy and security continues to be a top priority for the company, and he added that the narrative is “riddled with inconsistences” and “presented without important context.”

On Jan. 4, Zatko reported internally that the Risk Committee meeting might have been fraudulent, which triggered an Audit Committee investigation.

Agarwal fired him two weeks later. But Zatko complied with the company’s request to spell out his concerns in writing, even without access to his work email and documents, according to the complaint.

Since Zatko’s departure, Twitter has plunged further into chaos with Musk’s takeover, which the two parties agreed to in May. The stock price has fallen, many employees have quit, and Agrawal has dismissed executives and frozen big projects.

Zatko said he hoped that by bringing new scrutiny and accountability, he could improve the company from the outside.

“I still believe that this is a tremendous platform, and there is huge value and huge risk, and I hope that looking back at this, the world will be a better place, in part because of this.”

Even as a liberal who has attended abortion rights demonstrations and written about standing up to racism, I sometimes feel afraid to fully speak my mind.

In the classroom, backlash for unpopular opinions is so commonplace that many students have stopped voicing them, sometimes fearing lower grades if they don’t censor themselves.

According to a 2021 survey administered by College Pulse of over 37,000 students at 159 colleges, 80 percent of students self-censor at least some of the time.

Forty-eight percent of undergraduate students described themselves as “somewhat uncomfortable” or “very uncomfortable” with expressing their views on a controversial topic in the classroom.

When a class discussion goes poorly for me, I can tell.

The room felt tense. I saw people shift in their seats. Someone got angry, and then everyone seemed to get angry. After the professor tried to move the discussion along, I still felt uneasy. I became a little less likely to speak up again and a little less trusting of my own thoughts.

This anxiety affects not just conservatives. I spoke with Abby Sacks, a progressive fourth-year student. She said she experienced a “pile-on” during a class discussion about sexism in media

Throughout that semester, I saw similar reactions in response to other students’ ideas. I heard fewer classmates speak up. Eventually, our discussions became monotonous echo chambers. Absent rich debate and rigor, we became mired in socially safe ideas.

when criticism transforms into a public shaming, it stifles learning.

Professors have noticed a shift in their classrooms

I went to college to learn from my professors and peers. I welcomed an environment that champions intellectual diversity and rigorous disagreement

“Second, the dominant messages students hear from faculty, administrators and staff are progressive ones. So they feel an implicit pressure to conform to those messages in classroom and campus conversations and debates.”

I met Stephen Wiecek at our debate club. He’s an outgoing, formidable first-year debater who often stays after meetings to help clean up. He’s also conservative.

He told me that he has often “straight-up lied” about his beliefs to avoid conflict. Sometimes it’s at a party, sometimes it’s at an a cappella rehearsal, and sometimes it’s in the classroom. When politics comes up, “I just kind of go into survival mode,” he said. “I tense up a lot more, because I’ve got to think very carefully about how I word things. It’s very anxiety inducing.”

“First, students are afraid of being called out on social media by their peers,”

“It was just a succession of people, one after each other, each vehemently disagreeing with me,” she told me.

Ms. Sacks felt overwhelmed. “Everyone adding on to each other kind of energized the room, like everyone wanted to be part of the group with the correct opinion,” she said. The experience, she said, “made me not want to go to class again.” While Ms. Sacks did continue to attend the class, she participated less frequently. She told me that she felt as if she had become invisible.

Other campuses also struggle with this. “Viewpoint diversity is no longer considered a sacred, core value in higher education,”

Dr. Abrams said the environment on today’s campuses differs from his undergraduate experience. He recalled late-night debates with fellow students that sometimes left him feeling “hurt” but led to “the ecstasy of having my mind opened up to new ideas.”

He worries that self-censorship threatens this environment and argues that college administrations in particular “enforce and create a culture of obedience and fear that has chilled speech.”

Universities must do more than make public statements supporting free expression. We need a campus culture that prioritizes ideological diversity and strong policies that protect expression in the classroom.

Universities should refuse to cancel controversial speakers or cave to unreasonable student demands. They should encourage professors to reward intellectual diversity and nonconformism in classroom discussions. And most urgently, they should discard restrictive speech codes and bias response teams that pathologize ideological conflict.

We cannot experience the full benefits of a university education without having our ideas challenged, yet challenged in ways that allow us to grow.

"I realized that only legislation can change the situation. There was no time to educate so many people, and the change had be forced on the industry. There was no time to waste, so many girls were dieting to death."

also rejected evolution and instead believes in "intelligent design,” according to Discover magazine.

Pope Francis says evolution does not contradict church doctrine.

Guilt signals that we’ve violated morals we believe in; embarrassment shows that we’ve made a fool out of ourselves

We evolved lo earn from emotions and they shape our behavior continually. Fundamentally we try to avoid unpleasant emotions and experience pleasant ones because they indicate situations that are either beneficial or harmful for us.

How do we reconcile our enjoyment of social media even as we understand that the corporations who control them aren’t always acting in our best interests?

hat was because the underlying economic conditions hadn’t been changed or “disrupted,” to use a favorite Silicon Valley phrase. Google has to serve its shareholders, just like NBCUniversal does. As a result, many of the unappealing aspects of the legacy-media model have simply carried over into a digital age — namely, commercialism, consolidation, and centralization. In fact, the new system is even more dependent on advertising dollars than the one that preceded it, and digital advertising is far more invasive and ubiquitous

the popular narrative — new communications technologies would topple the establishment and empower regular people — didn’t accurately capture reality. Something more complex and predictable was happening. The old-media dinosaurs weren’t dying out, but were adapting to the online environment; meanwhile the new tech titans were coming increasingly to resemble their predecessors

I use lots of products that are created by companies whose business practices I object to and that don’t act in my best interests, or the best interests of workers or the environment — we all do, since that’s part of living under capitalism. That said, I refuse to invest so much in any platform that I can’t quit without remorse

these services aren’t free even if we don’t pay money for them; we pay with our personal data, with our privacy. This feeds into the larger surveillance debate, since government snooping piggybacks on corporate data collection. As I argue in the book, there are also negative cultural consequences (e.g., when advertisers are paying the tab we get more of the kind of culture marketers like to associate themselves with and less of the stuff they don’t) and worrying social costs. For example, the White House and the Federal Trade Commission have both recently warned that the era of “big data” opens new avenues of discrimination and may erode hard-won consumer protections.

I’m resistant to the tendency to place this responsibility solely on the shoulders of users. Gadgets and platforms are designed to be addictive, with every element from color schemes to headlines carefully tested to maximize clickability and engagement. The recent news that Facebook tweaked its algorithms for a week in 2012, showing hundreds of thousands of users only “happy” or “sad” posts in order to study emotional contagion — in other words, to manipulate people’s mental states — is further evidence that these platforms are not neutral. In the end, Facebook wants us to feel the emotion of wanting to visit Facebook frequently

social inequalities that exist in the real world remain meaningful online. What are the particular dangers of discrimination on the Internet?

That it’s invisible or at least harder to track and prove. We haven’t figured out how to deal with the unique ways prejudice plays out over digital channels, and that’s partly because some folks can’t accept the fact that discrimination persists online. (After all, there is no sign on the door that reads Minorities Not Allowed.)

just because the Internet is open doesn’t mean it’s equal; offline hierarchies carry over to the online world and are even amplified there. For the past year or so, there has been a lively discussion taking place about the disproportionate and often outrageous sexual harassment women face simply for entering virtual space and asserting themselves there — research verifies that female Internet users are dramatically more likely to be threatened or stalked than their male counterparts — and yet there is very little agreement about what, if anything, can be done to address the problem.

What steps can we take to encourage better representation of independent and non-commercial media? We need to fund it, first and foremost. As individuals this means paying for the stuff we believe in and want to see thrive. But I don’t think enlightened consumption can get us where we need to go on its own. I’m skeptical of the idea that we can shop our way to a better world. The dominance of commercial media is a social and political problem that demands a collective solution, so I make an argument for state funding and propose a reconceptualization of public media. More generally, I’m struck by the fact that we use these civic-minded metaphors, calling Google Books a “library” or Twitter a “town square” — or even calling social media “social” — but real public options are off the table, at least in the United States. We hand the digital commons over to private corporations at our peril.

6. You advocate for greater government regulation of the Internet. Why is this important?

I’m for regulating specific things, like Internet access, which is what the fight for net neutrality is ultimately about. We also need stronger privacy protections and restrictions on data gathering, retention, and use, which won’t happen without a fight.

I challenge the techno-libertarian insistence that the government has no productive role to play and that it needs to keep its hands off the Internet for fear that it will be “broken.” The Internet and personal computing as we know them wouldn’t exist without state investment and innovation, so let’s be real.

there’s a pervasive and ill-advised faith that technology will promote competition if left to its own devices (“competition is a click away,” tech executives like to say), but that’s not true for a variety of reasons. The paradox of our current media landscape is this: our devices and consumption patterns are ever more personalized, yet we’re simultaneously connected to this immense, opaque, centralized infrastructure. We’re all dependent on a handful of firms that are effectively monopolies — from Time Warner and Comcast on up to Google and Facebook — and we’re seeing increased vertical integration, with companies acting as both distributors and creators of content. Amazon aspires to be the bookstore, the bookshelf, and the book. Google isn’t just a search engine, a popular browser, and an operating system; it also invests in original content

So it’s not that the Internet needs to be regulated but that these big tech corporations need to be subject to governmental oversight. After all, they are reaching farther and farther into our intimate lives. They’re watching us. Someone should be watching them.

It also offers its experts' predictions about what the most-desired life skills (for young people, but ostensibly for everyone else, too) will be in the year 2020. Among the skills they highlighted: public problem-solving through cooperative work -- crowdsourcing and the like; the ability to search effectively for information online; the ability to distinguish the quality and veracity of online discoveries; the ability to synthesize, or combine facts and details from different sources into coherent narratives; the ability to concentrate; and the ability to distinguish between the signal and the noise as the information we're exposed to gets bigger, and broader, and more plentiful.

All these skills can be taught. The question is whether kids will learn them in school, or outside of it.

“Reciprocal Biomimicry Initiative.” The idea is to leverage human technology for the benefit of animals for a change.

since buying that first iPhone, I’ve grown too used to new worlds.

As everything gets faster and richer and denser with information, as a whole new dimension to our physical world evolves online, some possibilities open up, and others close down. The potential congeals into the actual, the possible calcifies into the practical. What is imaginable gets pared down into what was actually imagined

But things are by necessity amazing in a very specific way, and with a very specific visual grammar and conceptual environment — and that environment is one that is closed, controlled, packaged for us. We’re holding magic boxes, boxes that want to serve us and coddle us, instead of challenge us. And how can you love something that doesn’t challenge you?

The answer given in the first lecture — “What is Language?” — is that we are creatures with language, and that language as a uniquely human biological capacity appeared suddenly and quite late in the evolutionary story, perhaps 75,000 years ago.

Chomsky gave three lectures under the general title “What Kind of Creatures are We?”

Language, then, does not arise from the social/cultural environment, although the environment provides the stuff or input it works on. That input is “impoverished”; it can’t account for the creativity of language performance, which has its source not in the empirical world, but in an innate ability that is more powerful than the stimuli it utilizes and plays with. It follows that if you want to understand language, you shouldn’t look to linguistic behavior but to the internal mechanism — the Universal Grammar — of which particular linguistic behaviors are a non-exhaustive expression. (The capacity exceeds the empirical resources it might deploy.)

In his second lecture (“What Can We Understand?”), Chomsky took up the question of what humans are capable of understanding and his answer, generally, was that we can understand what we can understand, and that means that we can’t understand what is beyond our innate mental capacities

This does not mean, he said, that what we can’t understand is not real: “What is mysterious to me is not an argument that it does not exist.” It’s just that while language is powerful and creative, its power and creativity have limits; and since language is thought rather than an addition to or clothing of thought, the limits of language are the limits of what we can fruitfully think about

This is as good as it gets. There is “no evolution in our capacity for language.”

These assertions are offered as a counter to what Chomsky sees as the over-optimistic Enlightenment belief — common to many empiricist philosophies — that ours is a “limitless explanatory power” and that “we can do anything.”

In the third lecture (“What is the Common Good?”) Chomsky turned from the philosophy of mind and language to political philosophy and the question of what constitutes a truly democratic society

He likened dogmatic intellectual structures that interfere with free inquiry to coercive political structures that stifle the individual’s creative independence and fail to encourage humanity’s “richest diversity

He asserted that any institution marked by domination and hierarchy must rise to the challenge of justifying itself, and if it cannot meet the challenge, it should be dismantled.

He contrasted two accounts of democracy: one — associated by him with James Madison — distrusts the “unwashed” populace and puts its faith in representative government where those doing the representing (and the voting and the distributing of goods) constitute a moneyed and propertied elite

the other — associated by him with Adam Smith (in one of his moods), J. S. Mill, the 1960s and a tradition of anarchist writing — seeks to expand the franchise and multiply choices in the realms of thought, politics and economics. The impulse of this second, libertarian, strain of democracy, is “to free society from economic or theological guardianship,” and by “theological” Chomsky meant not formal religion as such but any assumed and frozen ideology that blocked inquiry and limited participation. There can’t, in short, be “too much democracy.”

It was thought of the highest order performed by a thinker, now 85 years old, who by and large eschewed rhetorical flourishes (he has called his own speaking style “boring” and says he likes it that way) and just did it, where ‘it” was the patient exploration of deep issues that had been explored before him by a succession of predecessors, fully acknowledged, in a conversation that is forever being continued and forever being replenished.

Yes, I said to myself, this is what we — those of us who bought a ticket on this particular train — do; we think about problems and puzzles and try to advance the understanding of them; and we do that kind of thinking because its pleasures are, in a strong sense, athletic and provide for us, at least on occasion, the experience of fully realizing whatever capabilities we might have. And we do it in order to have that experience, and to share it with colleagues and students of like mind, and not to make a moral or political point.

The term “master class” is a bit overused, but I feel no hesitation in using it here. It was a master class taught by a master, and if someone were to ask me what exactly is it that academics do, I would point to these lectures and say, simply, here it is, the thing itself.

In January 2013, astronomers used Kepler's data to estimate that there could be at least 17 billion Earth-sized exoplanets in the Milky Way galaxy.

The number of confirmed planets frequently increases because as scientists analyse the data they are able publish their results online immediately. But as the finds are not yet peer reviewed, the total figure remains subject to change.

"That's why the other catalogues just lag behind. The review is reliable as it's exactly the same as what the journals do."

"no consensus for the definition of a planet" a

"Some objects, like some Kepler planets, are declared 'confirmed planets' but have not been published in [referenced] articles. It does not mean that they will not be published later on, but it introduces another fuzziness in the tally," he added.

"I don't just want to know where the exoplanets are, I want to understand the stars, because they are the hosts for the planets. I want to understand the whole galaxy and the distribution of the stars because everything is connected," he explained.

For him, the most exciting discoveries are Earth-like planets which could be habitable.

This planet likely has the same mass as Earth but is outside the "habitable zone" as it circles its star far closer than Mercury orbits our Sun.
