Does Your Language Shape How You Think? - The New York Times - 0 views

  • When your language routinely obliges you to specify certain types of information, it forces you to be attentive to certain details in the world and to certain aspects of experience that speakers of other languages may not be required to think about all the time. And since such habits of speech are cultivated from the earliest age, it is only natural that they can settle into habits of mind that go beyond language itself, affecting your experiences, perceptions, associations, feelings, memories and orientation in the world.
  • BUT IS THERE any evidence for this happening in practice?
  • In recent years, various experiments have shown that grammatical genders can shape the feelings and associations of speakers toward objects around them

  • Do the emotional maps imposed by a gender system have higher-level behavioral consequences for our everyday life? Do they shape tastes, fashions, habits and preferences in the societies concerned? At the current state of our knowledge about the brain, this is not something that can be easily measured in a psychology lab. But it would be surprising if they didn’t.
  • The area where the most striking evidence for the influence of language on thought has come to light is the language of space — how we describe the orientation of the world around us
  • For many years, our mother tongue was claimed to be a “prison house” that constrained our capacity to reason. Once it turned out that there was no evidence for such claims, this was taken as proof that people of all cultures think in fundamentally the same way
  • The habits of mind that our culture has instilled in us from infancy shape our orientation to the world and our emotional responses to the objects we encounter, and their consequences probably go far beyond what has been experimentally demonstrated so far; they may also have a marked impact on our beliefs, values and ideologies. We may not know as yet how to measure these consequences directly or how to assess their contribution to cultural or political misunderstandings. But as a first step toward understanding one another, we can do better than pretending we all think the same.

How Headlines Change the Way We Think - The New Yorker - 0 views

  • a headline changes the way people read an article and the way they remember it. The headline frames the rest of the experience.
  • Psychologists have long known that first impressions really do matter—what we see, hear, feel, or experience in our first encounter with something colors how we process the rest of it. Articles are no exception.
  • By drawing attention to certain details or facts, a headline can affect what existing knowledge is activated in your head.

the biology of imagination - 0 views

  • the content of the imagination is of course determined more by culture than biology. But the capacity to imagine owes more to biology than culture.
  • Imagery is usually the product of one of the five senses (though it can also be generated without any sensory input at all, from the mere act of thinking or dreaming). Imagery typically comprises a mental representation of a state of affairs in the outside, physical world.
  • Since the disability that comprises classic autism is biological in origin, then children with autism are offering us a big clue about the biological basis of the imagination. Of course, when the meta-representational hardware develops normally, biology has done its job. From then on, the content of our imagination, whether we imagine an angry god or a school of wizardry, a mermaid or a devil, owes more to our specific culture than to biology. But the capacity to imagine depends on genes that build brains with a very specific kind of mechanism – one that we take for granted whenever we form relationships or fantasize.

Quote by Albert Einstein: "Imagination is more important than knowledge. F..." - 0 views

  • “Imagination is more important than knowledge. For knowledge is limited to all we now know and understand, while imagination embraces the entire world, and all there ever will be to know and understand.” ― Albert Einstein

Bilingual brain boost: Two tongues, two minds | New Scientist - 0 views

  • Speaking a second language can change everything from problem-solving skills to personality – almost as if you are two people
  • Cognitive enhancement is just the start. According to some studies, my memories, values, even my personality, may change depending on which language I happen to be speaking. It is almost as if the bilingual brain houses two separate minds. All of which highlights the fundamental role of language in human thought
  • The view of bilingualism has not always been this rosy. For many parents like mine, the decision to raise children speaking two languages was controversial. Since at least the 19th century, educators warned that it would confuse the child, making them unable to learn either language properly. At best, they thought the child would become a jack-of-all-trades and master of none. At worst, they suspected it might hinder other aspects of development, resulting in a lower IQ
  • ...5 more annotations...
  • a key study in the 1960s by Elizabeth Peal and Wallace Lambert at McGill University in Montreal, Canada, found that the ability to speak two languages does not stunt overall development. On the contrary, when controlling for other factors which might also affect performance, such as socioeconomic status and education, they found that bilinguals outperformed monolinguals in 15 verbal and non-verbal tests
  • Besides giving us bilinguals a brain boost, speaking a second language may have a profound effect on behaviour. Neuroscientists and psychologists are coming to accept that language is deeply entwined with thought and reasoning, leading some to wonder whether bilingual people act differently depending on which language they are speaking. That would certainly tally with my experience. People often tell me that I seem different when I speak English compared with when I speak French.
  • One explanation is that each language brings to mind the values of the culture we experienced while learning it, says Nairán Ramírez-Esparza, a psychologist at the University of Washington in Seattle. She recently asked bilingual Mexicans to rate their personality in English and Spanish questionnaires. Modesty is valued more highly in Mexico than it is in the US, where assertiveness gains respect, and the language of the questions seemed to trigger these differences. When questioned in Spanish, each volunteer was more humble than when the survey was presented in English
  • Much has been made of the difficulties of learning a new language later in life, but the evidence so far suggests the effort should pay off. “You can learn another language at any age, you can learn it fluently, and you can see benefits to your cognitive system,” says Marian. Bialystok agrees that late language-learners gain an advantage, even if the performance boost is usually less pronounced than in bilingual speakers. “Learn a language at any age, not to become bilingual, but just to remain mentally stimulated,” she says. “That’s the source of cognitive reserve.”
  • As it is, I’m grateful that particular challenge is behind me. My mother could never have guessed the extent to which her words would change my brain and the way I see my world, but I’m certain it was worth the effort. And for all that I just have to say: Merci!

How to Defeat Those Who Are Waging War on Science - Scientific American Blog Network - 0 views

  • new language of this war—a subtle, yet potentially damaging form of science skepticism
  • The systematic use of so-called “uncertainty” surrounding well-established scientific ideas has proven to be a reliable method for manipulating public perception and stalling political action.
  • Make no mistake: the War on Science is going to affect you, whether you are a scientist or not. It is going to affect everything—ranging from the safety of the food we eat, the water we drink, the air we breathe, and the kind of planet we live on.
  • ...8 more annotations...
  • The reality is that science touches everything we do, and everyone we love
  • Do we want to be the America that embraces science and the pursuit of knowledge to advance our health, safety, prosperity, and security, making America the leader of the civilized world? Or do want America to mimic failed regimes of the past, where knowledge and science were deliberately suppressed to benefit a few, to funnel more profits into dying industries, and placate the prejudices of a mob
  • Traditionally, scientists have been coached to steer clear of the political fray. But if the past few weeks have taught us anything, it’s that now is the time for a quantum leap of political relevance.
  • You cannot isolate science from politics, or politics from science
  • That is precisely why scientists shouldn’t shy away from engaging in political conversations. Now more than ever, it is necessary to be participating in them
  • At the very least, we all share a deeply-held fascination with our natural world. The search for meaning, the understanding of something bigger than ourselves, is of universal significance.
  • In today’s world, facts alone are not enough to win debates, let alone people’s hearts and minds. Research shows that increasing scientific knowledge can often deepen the divide between people on polarizing issues. “Individuals subconsciously resist factual information that threatens their defining values,” a recent study points out
  • America has a choice to make. A choice between advancing civilization or bringing it down. A choice between knowledge and chaos. Now, everyone must choose which side they are on.

Darwin's Influence on Modern Thought - Scientific American - 0 views

  • Great minds shape the thinking of successive historical periods. Luther and Calvin inspired the Reformation; Locke, Leibniz, Voltaire and Rousseau, the Enlightenment. Modern thought is most dependent on the influence of Charles Darwin
  • one needs schooling in the physicist’s style of thought and mathematical techniques to appreciate Einstein’s contributions in their fullness. Indeed, this limitation is true for all the extraordinary theories of modern physics, which have had little impact on the way the average person apprehends the world.
  • The situation differs dramatically with regard to concepts in biology.
  • ...10 more annotations...
  • Many biological ideas proposed during the past 150 years stood in stark conflict with what everybody assumed to be true. The acceptance of these ideas required an ideological revolution. And no biologist has been responsible for more—and for more drastic—modifications of the average person’s worldview than Charles Darwin
  • . Evolutionary biology, in contrast with physics and chemistry, is a historical science—the evolutionist attempts to explain events and processes that have already taken place. Laws and experiments are inappropriate techniques for the explication of such events and processes. Instead one constructs a historical narrative, consisting of a tentative reconstruction of the particular scenario that led to the events one is trying to explain.
  • The discovery of natural selection, by Darwin and Alfred Russel Wallace, must itself be counted as an extraordinary philosophical advance
  • The concept of natural selection had remarkable power for explaining directional and adaptive changes. Its nature is simplicity itself. It is not a force like the forces described in the laws of physics; its mechanism is simply the elimination of inferior individuals
  • A diverse population is a necessity for the proper working of natural selection
  • Because of the importance of variation, natural selection should be considered a two-step process: the production of abundant variation is followed by the elimination of inferior individuals
  • By adopting natural selection, Darwin settled the several-thousandyear- old argument among philosophers over chance or necessity. Change on the earth is the result of both, the first step being dominated by randomness, the second by necessity
  • Another aspect of the new philosophy of biology concerns the role of laws. Laws give way to concepts in Darwinism. In the physical sciences, as a rule, theories are based on laws; for example, the laws of motion led to the theory of gravitation. In evolutionary biology, however, theories are largely based on concepts such as competition, female choice, selection, succession and dominance. These biological concepts, and the theories based on them, cannot be reduced to the laws and theories of the physical sciences
  • Despite the initial resistance by physicists and philosophers, the role of contingency and chance in natural processes is now almost universally acknowledged. Many biologists and philosophers deny the existence of universal laws in biology and suggest that all regularities be stated in probabilistic terms, as nearly all so-called biological laws have exceptions. Philosopher of science Karl Popper’s famous test of falsification therefore cannot be applied in these cases.
  • To borrow Darwin’s phrase, there is grandeur in this view of life. New modes of thinking have been, and are being, evolved. Almost every component in modern man’s belief system is somehow affected by Darwinian principles

What's the point of theoretical physics? - 1 views

  • Discoveries such as gravitational waves and the Higgs boson can inspire wonder at the complex beauty of the universe no matter how little you really understand them.
  • But some people will always question why they should care about scientific advances that have no apparent impact on their daily life
  • Yet the reality is that purely theoretical studies in physics can sometimes lead to amazing changes in our society. In fact, several key pillars on which our modern society rests, from satellite communication to computers, were made possible by investigations that had no obvious application at the time.
  • ...4 more annotations...
  • Around 100 years ago, quantum mechanics was a purely theoretical topic, only developed to understand certain properties of atoms
  • But today, quantum mechanics is the basis of our use of all semiconductors in computers and mobile phones
  • Despite these direct and indirect benefits, most theoretical physicists have a very different motive for their work. They simply want to improve humanity’s understanding of the universe. While this might not immediately impact everyone’s lives, I believe it is just as important a reason for pursuing fundamental research
  • It somehow seems that every new level of understanding we achieve comes in tandem with new, more fundamental questions. It is never enough to know what we now know. We always want to continue looking behind newly arising curtains. In that respect, I consider fundamental physics a basic part of human culture.

Sanctuary Cities Keep Communities Safe | Debate Club | US News - 0 views

  • many state and local law enforcement agencies adopted policies to enhance public safety and community trust. They did this because they know that when people are afraid the police might ask about immigration status, they are less likely to report crimes and cooperate with investigations. As a result, criminals thrive, and the general public suffers.
  • We should learn from the tragedy in San Francisco and pursue real solutions to make our communities safer. We shouldn't use tragedy as an excuse to promote a deportation-only agenda
  •  
    To what extent do sanctuary cities help control crime and increase community safety?

Perspectives: Why humanity needs a God of creativity | New Scientist - 0 views

  • So the unfolding of the universe – biotic, and perhaps abiotic too – appears to be partially beyond natural law. In its place is a ceaseless creativity, with no supernatural creator. If, as a result of this creativity, we cannot know what will happen
  • then reason, the Enlightenment’s highest human virtue, is an insufficient guide to living our lives. We must use reason, emotion, intuition, all that our evolution has brought us. But that means understanding our full humanity: we need Einstein and Shakespeare in the same room.
  • Yet what is more awesome: to believe that God created everything in six days, or to believe that the biosphere came into being on its own, with no creator, and partially lawlessly? I find the latter proposition so stunning, so worthy of awe and respect, that I am happy to accept this natural creativity in the universe as a reinvention of “God”. From it, we can build a sense of the sacred that encompasses all life and the planet itself. From it, we can change our value system across the globe and try, together, to ease the fears of religious fundamentalists with a safe, sacred space we can share. And from it we can, if we are wise, find means to avert wars of civilisations, the ravages of global warming, and the potential disaster of peak oil.

Anaesthesia: What really happens when the lights go out | New Scientist - 0 views

  • We've used it for hundreds of years, but we still don't know how anaesthesia works. Finding out could lead to safer drugs and unlock the mystery of consciousness
  • The case isn’t yet cracked, but the latest theories could provide opportunities to limit potential harms. At the very least, they show how inventive we are forced to be in trying to understand what really goes on when the lights go out

To advance science we need to think about the impossible | New Scientist - 0 views

  • Science sets out what we think is true – but when it gets stuck, it’s time to explore what we think isn’t
  • science has always advanced in small steps, paving the way for occasional leaps. But sometimes fact-collecting yields nothing more than a collection of facts; no revelation follows. At such times, we need to step back from the facts we know and imagine alternatives: in other words, to ask “what if?”
  • That was how Albert Einstein broke the bind in which physics found itself in the early 20th century. His conception of a scenario that received wisdom deemed impossible – that light’s speed is always the same, regardless of how you look at it – led to special relativity and demolished what we thought we knew about space and time.

  • Despite its dependence on hard evidence, science is a creative discipline. That creativity needs nurturing, even in this age of performance targets and impact assessments. Scientist need to flex their imaginations, too.
  • “Let us dare to dream,” the chemist August Kekulé once suggested, “and then perhaps we may learn the truth.”
  • Physics isn’t the only field that might benefit from a judicious dose of what-iffery. Attempts to understand consciousness are also just inching forward

  • These include the superior colliculus, which is crucial in eye movements and may have other sensory functions; and, probably, circuits running through the amygdala, which registers emotion.
  • In time, and with practice, people with brain injuries may learn to lean more heavily on such subconscious or semiconscious systems, and perhaps even begin to construct some conscious vision from them. “It’s not clear how sharp it would be,” Dr. Held said. “Probably a vague, low-resolution spatial sense. But it might allow them to move around more independently.”

How Do Astronomers Actually Find Exoplanets? | Science | Smithsonian - 1 views

  • generation ago, the idea of a planet orbiting a distant star was still in the realm of science fiction. But since the discovery of the first exoplanet in 1988, we've found hundreds of them, with the discoveries coming at a faster rate over time.
  • But the vast majority of all these distant planets have one thing in common—with a few exceptions, they're too far away for us to see, even with our most powerful telescopes. If that's the case, how do astronomers know they're there?

Does nonpartisan journalism have a future? - 0 views

  • Media outlets make decisions about how to position themselves within a market and how to signal to news consumers what kinds outlets they are in ideological terms. But they also interact strategically with politicians, who use journalists’ ideological leanings and accusations of leanings to undermine the credibility of even the most valid criticisms.
  • While Republican politicians have decried liberal media bias for decades, none has done so as vehemently as Trump, who polarizes the media in a way that may not leave an escape.
  • These media outlets, though, muddy the signals: A nonpartisan journalist strives to levy valid criticism, but a partisan journalist will always criticize the opposing party. Thus a weakly informed voter will have a difficult time distinguishing between, say, a valid accusation from a nonpartisan journalist that a Republican is lying and partisan bias from a left-wing journalist who fails to acknowledge that bias.
  • ...1 more annotation...
  • Unfortunately, then, the nonpartisan press is essentially stuck, at least until Donald Trump is out of office. While there is no longer a “he said, she said” campaign, the fact that Trump is not only the president but the head of the Republican Party makes his statements informal positions of the Republican Party. For the press to attack those statements as lies is to place themselves in opposition to the Republican Party, making them de facto Democratic partisans. Because Trump is an entertainer rather than a policymaker, it is difficult for the press to even interview him as a normal political figure since he does not respond to facts in conventional ways. Each time he lies, any media outlet that aspires to objectivity must decide whether to point it out – which would make it indistinguishable from the Democratic-aligned press – or to allow the lie to go unremarked, thereby remaining complicit in the lie, tacitly aiding the Republican Party. Neither is likely to inform anyone in any meaningful way, which renders the model of the neutral press nearly inoperable.

A Psychologist Analyzes Donald Trump's Personality - The Atlantic - 0 views

  • From unsympathetic journalists to political rivals, Trump calls his opponents “disgusting” and writes them off as “losers.” By the standards of reality TV, Trump’s disagreeableness may not be so shocking. But political candidates who want people to vote for them rarely behave like this.
  • Trump seems capable of a similar toughness and strategic pragmatism, although the cool rationality does not always seem to fit, probably because Trump’s disagreeableness appears so strongly motivated by anger.
  • Research shows that people low in agreeableness are typically viewed as untrustworthy. Dishonesty and deceit brought down Nixon and damaged the institution of the presidency. It is generally believed today that all politicians lie, or at least dissemble, but Trump appears extreme in this regard. Assessing the truthfulness of the 2016 candidates’ campaign statements, PolitiFact recently calculated that only 2 percent of the claims made by Trump are true, 7 percent are mostly true, 15 percent are half true, 15 percent are mostly false, 42 percent are false, and 18 percent are “pants on fire.” Adding up the last three numbers (from mostly false to flagrantly so), Trump scores 75 percent. The corresponding figures for Ted Cruz, John Kasich, Bernie Sanders, and Hillary Clinton, respectively, are 66, 32, 31, and 29 percent.

What Happens When You Trust Too Much - The Atlantic - 0 views

  • The thing about having a highly social mind is that anxiety lurks just around the corner. High levels of anxiety are also reported with Williams Syndrome, whether it's the eagerness to please you, or simply to know when Christmas is coming. But now that employers and job programs are starting to better understand the needs of people with Williams Syndrome, the workplace might be getting more amenable for them. Still, for these individuals, does going to work mean learning to temper their trust?
  • "I'm very wary now of trusting anyone," Koch says. "I don’t want to go through what I went through at my past jobs. I guard things. I'm quiet. I'm cautious, period."

Joe Biden's tears show politics doesn't have to be macho | Angelina Chapin | Opinion | ... - 0 views

  • Too many men still think a woman who cries is acting hysterical. For some baffling reason, punching a hole in the wall or another person in the face is a more culturally acceptable way to release pain than sobbing into a pillow. And politics is no different. Anger makes you a strong candidate while sadness makes you frail. The result is that many female politicians swallow their emotions in an effort to appear tough.
  • The stereotype that women are overly emotional, hormonal beings who are unfit to lead still exists. Powerful men like Obama and Biden who embrace their feelings on a public stage help to combat the ridiculous political stigma against sensitivity. Every time these political powerhouses become misty-eyed, they send the message that having human feelings doesn’t equal incompetence.
  • By being the kind of men who are unafraid to openly love one another and cry in public, they have sent a message to aspiring female politicians that being human doesn’t come with a penalty.

Does your smartphone make you less likely to trust others? - 0 views

  • When trust between people in a country goes up, for example, so does economic growth. At the individual level, people who trust others more also tend to have better health and higher well-being.Could our increasing reliance on information from devices, rather than from other people, be costing us opportunities to build social capital?
  • As information technology continues to make our lives easier, our findings highlight the possible social costs of constant information access: By turning to convenient electronic devices, people may be forgoing opportunities to foster trust – a finding that seems particularly poignant in the present political climate.
