"Why do people see faces in nature, interpret window stains as human figures, hear voices in random sounds generated by electronic devices or find conspiracies in the daily news? A proximate cause is the priming effect, in which our brain and senses are prepared to interpret stimuli according to an expected model. UFOlogists see a face on Mars. Religionists see the Virgin Mary on the side of a building. Paranormalists hear dead people speaking to them through a radio receiver.\n1\nConspiracy theorists think 9/11 was an inside job by the Bush administration. Is there a deeper ultimate cause for why people believe such weird things? There is. I call it "patternicity," or the tendency to find meaningful patterns in meaningless noise."

"When you take a sip of Cabernet, what are you tasting? The grape? The tannins? The oak barrel? Or the price? Believe it or not, the most dominant flavor may be the dollars. Thanks to the work of some intrepid and wine-obsessed economists (yes, there is an American Association of Wine Economists), we are starting to gain a new understanding of the relationship between wine, critics and consumers."

Thanks to Felix (TAS2010) for passing this one on!

"We are, I believe, witnessing something new in American politics. Last year, looking at claims that we can cut taxes, avoid cuts to any popular program and still balance the budget, I observed that Republicans seemed to have lost interest in the war on terror and shifted focus to the war on arithmetic. But now the G.O.P. has moved on to an even bigger project: the war on logic. "

"Teri Horton is a 74-year-old retired truck driver with an eighth grade education. She likes to gamble a bit, and now she thinks she has hit the jackpot. Not in a casino, but in the high-stakes world of modern art. Teri isn't the kind of person who knows-or cares-much about art. But as CNN's Anderson Cooper reports, she has caused a stir in the upper reaches of the art world because of a painting she bought years ago, a painting she now believes is the work of the famous abstract expressionist Jackson Pollock. If Teri's painting is by Pollock, it would likely be worth tens of millions of dollars. Not bad, considering she bought it as a gift for a friend and only paid $5 for it in a thrift shop in San Bernardino, Calif."

"I've come to believe that these failures spring from a single failure: reliance on an overly simplistic view of human nature. We have a prevailing view in our society - not only in the policy world, but in many spheres - that we are divided creatures. Reason, which is trustworthy, is separate from the emotions, which are suspect. Society progresses to the extent that reason can suppress the passions. This has created a distortion in our culture. We emphasize things that are rational and conscious and are inarticulate about the processes down below. We are really good at talking about material things but bad at talking about emotion. When we raise our kids, we focus on the traits measured by grades and SAT scores. But when it comes to the most important things like character and how to build relationships, we often have nothing to say. Many of our public policies are proposed by experts who are comfortable only with correlations that can be measured, appropriated and quantified, and ignore everything else. Yet while we are trapped within this amputated view of human nature, a richer and deeper view is coming back into view. It is being brought to us by researchers across an array of diverse fields: neuroscience, psychology, sociology, behavioral economics and so on. "

"Charles Darwin has had a remarkable record over the past century, not only in the affirmation of evolution by natural selection, but in the number of his more specific ideas that have been proved correct. He may, however, have been wrong about invasive species, at least where amphibians are concerned. Darwin believed that when an invasive species entered a region where a closely related species already existed, it would most likely be unsuccessful because of a competition for resources. "Instead, we found the opposite pattern with amphibians," said Reid Tingley, a biologist at the University of Sydney. "When frogs and toads and salamanders invade an area where a similar species exists, they are more, not less, likely to establish themselves." "

So, sometimes even Darwin's predictions turn out to be wrong!

Humans have often asserted a fundamental difference between themselves and other animals. One of these assertions which has had many proponents into the twentieth century is that humans differ from animals in their use of language. In the past thirty years this assertion has been the subject of much debate as scientists have researched language use by apes. (I use the term "ape" to refer to "great ape" in this essay, as many of my sources do. There have apparently been no language experiments with gibbons or siamangs.) Extraordinary claims have been made by some researchers about the linguistic capabilities of their subjects, mostly chimpanzees. These claims have been refuted and counter-refuted many times, and the literature on the subject is extensive. In this essay I will examine the question of how much, if at all, primates are able to communicate using language. I will then examine the ethical issues surrounding the teaching of language to apes. What is language? First, what is language, and how does it differ from other forms of communication? There does not exist a universally accepted definition of language, or criteria for its use; this is one of the reasons for the disagreement among scientists about whether apes can use language. Language consists of various aspects which people believe are more or less important, for example, grammar, symbol usage, the ability to represent real-world situations, and the ability to articulate something new (Wallman 1992: 6). Duane Rumbaugh describes language as "an infinitely open system of communication" (Rumbaugh 1977b: xx). Some people say that anything an ape can do is not language; of course, if these are the same people who say that language defines us as humans, and an ape can learn sign language, then they are saying that deaf people who use sign language are not human (Patterson & Linden 1981: 119-120). One famous view of language is Charles Hockett's seven key properties: duality, productivity, arbitrariness,

"RESEARCHERS say they have solved a conundrum about human perception that has stumped philosophers and scientists alike for three centuries. Irish politician William Molyneux first posed the question in a letter to the great British thinker John Locke written 323 years ago. Imagine, Molyneux wrote, that a man blind from birth who has learned to identify objects - a sphere and a cube, for example - only through his sense of touch is suddenly able to see. The puzzle, he continued, is: "Whether he Could, by his Sight, and before he touch them, know which is the Globe and which the Cube?" For philosophers of the time, answering "Molyneux's question", as it became known, would resolve a fundamental uncertainty about the human mind. Empiricists believed that we are born blank slates, and become the sum total of our accumulated experience. So-called "nativists" countered that our minds are, from the outset, pre-stocked with ideas waiting to be activated by sight, sound and touch. If a blind man who miraculously recovered his sight could instantly distinguish the cube from the globe it would mean the knowledge was somehow innate, they argued. More recently, this "nurture vs. nature" debate has found its counterpart in modern neuroscience."

"The alteration of photos for propaganda purposes has been with us as long as photography itself; it is not an invention of the digital age. But while digitally altered photographs can easily fool the eye, they often leave telltale footprints that allow them to be unmasked as forgeries. There are many famous altered photographs, from a Matthew Brady photograph of Abraham Lincoln's head composited on to John Calhoun's body to the endlessly altered photographs from Soviet Russia. An entire book, "The Commissar Vanishes," by David King, is devoted to Soviet whims about who should be included (or deleted) in photographs. In the series shown above, Stalin is accompanied by three officials, then two, then one, as they successively fall out of favor and are cropped and airbrushed into non-existence. (In the end, in a painting based on the photograph, he stands alone.) We understand Stalin's intentions by removing comrades, but what is the purpose of these Iranian missile photographs? They are clearly altered. The question remains: Why, and to what end?"

Isn't this kind of like the reading we had...with the Uncertainty of Knowledge assignment? It talks about how science theories can be true because we believe them to be true, but because time changes and everything is different all the time, they are always easy to be proven wrong, and subject to change. That is like what you said about scientific theories being subject to future questioning. What we perceive to be an atom may not be what Socrates perceived as an atom, or some scientist from year 3000 perceives it. Science is always changing and therefore I agree that the laws that are made are always "refinable".

Fake speed humps, as flat as the street, but designed to appear three-dimensional, fool drivers into slowing down.

Are these Philly speed bump illusions better than Vancouver's? Does this suggest that Canadians are just plain demented? For more on Canadians: http://www.youtube.com/watch?v=pILPiB-07uI

The idea that your mother tongue shapes your experience of the world may be true after all.

Last week, the highly regarded medical journal, The Lancet, retracted a much debated 1998 study that had linked the measles, mumps and rubella vaccine to autism. The study was retracted after concerns about ethical breaches by one of the study authors. In addition, 10 of the 13 co-authors have disavowed the study's conclusions. "We fully retract this paper from the published record," The Lancet editors said in a statement. But the damage has been done. The paper has fueled fears about the risks of childhood vaccinations and autism, particularly the M.M.R. vaccine, despite numerous studies showing no link.

"Horizon explores the strange and wonderful world of illusions - and reveals the tricks they play on our senses and why they fool us."

"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" 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 (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. The theory of motivated reasoning builds on a key insight of modern neuroscience (PDF): Reasoning is actually suffused with emotion (or what researchers often call "affect"). Not only are the two inseparable, but our positive or negative feelings about people, things, and ideas arise much more rapidly than our conscious thoughts, in a matter of milliseconds-fast enough to detect with an EEG device, but long before we're aware of it. That shouldn't be surprising: Evolution required us to react very quickly to stimuli in our environment. It's a "basic human survival skill," explains political scientist Arthur Lupia of the University of Michigan. We push threatening information away; we pull friendly information close. We apply fight-or-flight reflexes not only to predators, but to data itself."
