BBC News - UN mulls ethics of 'killer robots' - 0 views
-
So-called killer robots are due to be discussed at the UN Human Rights Council, meeting in Geneva. A report presented to the meeting will call for a moratorium on their use while the ethical questions they raise are debated. The robots are machines programmed in advance to take out people or targets, which - unlike drones - operate autonomously on the battlefield. They are being developed by the US, UK and Israel, but have not yet been used. Supporters say the "lethal autonomous robots", as they are technically known, could save lives, by reducing the number of soldiers on the battlefield. But human rights groups argue they raise serious moral questions about how we wage war, reports the BBC's Imogen Foulkes in Geneva. They include: Who takes the final decision to kill? Can a robot really distinguish between a military target and civilians?
Why We Need Answers: The Theory of Cognitive closure : The New Yorker - 0 views
-
The human mind is incredibly averse to uncertainty and ambiguity; from an early age, we respond to uncertainty or lack of clarity by spontaneously generating plausible explanations. What’s more, we hold on to these invented explanations as having intrinsic value of their own. Once we have them, we don’t like to let them go.
-
Heightened need for cognitive closure can bias our choices, change our preferences, and influence our mood. In our rush for definition, we tend to produce fewer hypotheses and search less thoroughly for information. We become more likely to form judgments based on early cues (something known as impressional primacy), and as a result become more prone to anchoring and correspondence biases (using first impressions as anchors for our decisions and not accounting enough for situational variables). And, perversely, we may not even realize how much we are biasing our own judgments.

In 2010, Kruglanski and colleagues looked specifically at the need for cognitive closure as part of the response to terrorism.

4 | The Golden Ratio: Design's Biggest Myth | Co.Design | business + design - 0 views
-
The golden ratio's aesthetic bona fides are an urban legend, a myth, a design unicorn. Many designers don't use it, and if they do, they vastly discount its importance. There's also no science to really back it up.
-
"Strictly speaking, it's impossible for anything in the real-world to fall into the golden ratio, because it's an irrational number," says Keith Devlin, a professor of mathematics at Stanford University.

You Don't Really Prefer The Golden Ratio In the real world, people don't necessarily prefer the golden ratio.

Angela Merkel: internet search engines are 'distorting perception' | World news | The G... - 0 views

Angela Merkel has called on major internet platforms to divulge the secrets of their algorithms, arguing that their lack of transparency endangers debating culture. The German chancellor said internet users had a right to know how and on what basis the information they received via search engines was channelled to them. Speaking to a media conference in Munich, Merkel said: “I’m of the opinion that algorithms must be made more transparent, so that one can inform oneself as an interested citizen about questions like ‘what influences my behaviour on the internet and that of others?’. “Algorithms, when they are not transparent, can lead to a distortion of our perception, they can shrink our expanse of information.”
Scientists Unveil New 'Tree of Life' - The New York Times - 1 views
-
A team of scientists unveiled a new tree of life on Monday, a diagram outlining the evolution of all living things. The researchers found that bacteria make up most of life’s branches.
-
In his 1859 book “On the Origin of Species,” Charles Darwin envisioned evolution like a branching tree.
-
In the 1970s, Carl Woese of the University of Illinois and his colleagues published the first “universal tree of life” based on this approach. They presented the tree as three great trunks.

How can parents foster grit in their children?The parenting style that is good for grit is also the parenting style good for most other things: Be really, really demanding, and be very, very supportive. By this I don’t mean material things; I mean emotional support.

Among the defenders of the project, however, is Anne Churchland, a neuroscientist at Cold Spring Harbor Laboratory who studies how people make decisions. In 2001, she started Anne’s List, a directory of 170 women in computational neuroscience, intended to silence claims that no good female scientists existed in that field.Her research suggests that someone you recently had lunch with or someone from your hometown might spring to mind when selecting a speaker, even though neither has anything to do with science.“It doesn’t feel like irrelevant information influences our judgment, but it does,” Dr. Churchland said.
Evidence Rebuts Chomsky's Theory of Language Learning - Scientific American - 1 views
-
Much of Noam Chomsky’s revolution in linguistics—including its account of the way we learn languages—is being overturned
-
research shows that young children use various types of thinking that may not be specific to language at all—such as the ability to classify the world into categories (people or objects, for instance) and to understand the relations among things. These capabilities, coupled with a unique human ability to grasp what others intend to communicate, allow language to happen. The new findings indicate that if researchers truly want to understand how children, and others, learn languages, they need to look outside of Chomsky’s theory for guidance.
-
All of this leads ineluctably to the view that the notion of universal grammar is plain wrong. Of course, scientists never give up on their favorite theory, even in the face of contradictory evidence, until a reasonable alternative appears. Such an alternative, called usage-based linguistics, has now arrived.
Playing God - Radiolab - 2 views

When people are dying and you can only save some, how do you choose? Maybe you save the youngest. Or the sickest. Maybe you even just put all the names in a hat and pick at random. Would your answer change if a sick person was standing right in front of you? In this episode, we follow New York Times reporter Sheri Fink as she searches for the answer. In a warzone, a hurricane, a church basement, and an earthquake, the question remains the same. What happens, what should happen, when humans are forced to play god?
The Difference Between Rationality and Intelligence - The New York Times - 0 views
-
ARE you intelligent — or rational? The question may sound redundant, but in recent years researchers have demonstrated just how distinct those two cognitive attributes actually are.
-
If an I.Q. test measures something like raw intellectual horsepower (abstract reasoning and verbal ability), a test of R.Q. would measure the propensity for reflective thought — stepping back from your own thinking and correcting its faulty tendencies.

we not only discount or dismiss scientific information inconsistent with our ideology; we may also distrust and attack its source(s).

Furthermore, and contrary to popular belief, this biased processing is most likely to occur among people who have greater cognitive and reasoning capabilities–not less. Where the two sets of explanations for ideological divides on science differ is on how motivated reasoning leads to bias.
The Science of Why We Don't Believe Science - 2 views

"A MAN WITH A CONVICTION is a hard man to change. Tell him you disagree and he turns away. Show him facts or figures and he questions your sources. Appeal to logic and he fails to see your point." So wrote the celebrated Stanford University psychologist Leon Festinger [1] (PDF), in a passage that might have been referring to climate change denial—the persistent rejection, on the part of so many Americans today, of what we know about global warming and its human causes. But it was too early for that—this was the 1950s—and Festinger was actually describing a famous case study [2] in psychology. Festinger and several of his colleagues had infiltrated the Seekers, a small Chicago-area cult whose members thought they were communicating with aliens—including one, "Sananda," who they believed was the astral incarnation of Jesus Christ. The group was led by Dorothy Martin, a Dianetics devotee who transcribed the interstellar messages through automatic writing.
-
In the annals of denial, it doesn't get much more extreme than the Seekers. They lost their jobs, the press mocked them, and there were efforts to keep them away from impressionable young minds. But while Martin's space cult might lie at on the far end of the spectrum of human self-delusion, there's plenty to go around. And since Festinger's day, an array of new discoveries in psychology and neuroscience has further demonstrated how our preexisting beliefs, far more than any new facts, can skew our thoughts and even color what we consider our most dispassionate and logical conclusions. This tendency toward so-called "motivated reasoning [5]" helps explain why we find groups so polarized over matters where the evidence is so unequivocal: climate change, vaccines, "death panels," the birthplace and religion of the president [6] (PDF), and much else. It would seem that expecting people to be convinced by the facts flies in the face of, you know, the facts.

Pondering Miracles, Medical and Religious - The New York Times - 0 views
-
The tribunal that questioned me was not juridical, but ecclesiastical. I was not asked about my faith. (For the record, I’m an atheist.) I was not asked if it was a miracle. I was asked if I could explain it scientifically. I could not, though I had come armed for my testimony with the most up-to-date hematological literature, which showed that long survivals following relapses were not seen.
-
When, at the end, the Vatican committee asked if I had anything more to say, I blurted out that as much as her survival, thus far, was remarkable, I fully expected her to relapse some day sooner or later. What would the Vatican do then, revoke the canonization? The clerics recorded my doubts. But the case went forward and d’Youville was canonized on Dec. 9, 1990.
-
Respect for our religious patients demands understanding and tolerance; their beliefs are as true for them as the “facts” may be for physicians. Now almost 40 years later, that mystery woman is still alive and I still cannot explain why. Along with the Vatican, she calls it a miracle. Why should my inability to offer an explanation trump her belief? However they are interpreted, miracles exist, because that is how they are lived in our world.
Passing My Disability On to My Children - The New York Times - 0 views
-
Occasionally, I come across the term “designer baby,” and I am reminded that some parents now have the option to screen or modify the genes of their unborn children to ensure or avoid certain traits. It always gives me a feeling of unease. Obviously, I did not take this route — partly because, at least with my son, I never had to actually make the decision. My third child, Eliza, was a late midlife accident. I chose to have her despite the possibility she would have XLH, but would I have made the same decision in a planned pregnancy or if given a choice much earlier in the process? I can’t help suspecting that because of advances in genetic mapping, genetic testing, the sheer range of prenatal choices, chances are that in a generation or two, there will be no one in the world who has XLH, no one who looks like me or my children — at least not in the so-called developed world — and I don’t know how to feel about that.
