False Memories of Fabricated Political Events: "Study asks 5,269 people about fabricated political event. 50% remember the false event, 27% saw it on the news" by S. Frenda, E. Knowles, W. Saletan, E. Loftus (pdf) https://papers.ssrn.com/sol3...
false memories.jpg
Abstract: "In the largest false memory study to date, 5,269 participants were asked about their memories for three true and one of five fabricated political events. Each fabricated event was accompanied by a photographic image purportedly depicting that event. Approximately half the participants falsely remembered that the false event happened, with 27% remembering that they saw the events happen on the news. Political orientation appeared to influence the formation of false memories, with conservatives more likely to falsely remember seeing Barack Obama shaking hands with the president of Iran, and liberals more likely to remember George W. Bush vacationing with a baseball celebrity during the Hurricane Katrina disaster. A follow-up study supported the explanation that events are more easily implanted in memory when they are congruent with a person's preexisting attitudes and evaluations, in part because attitude-congruent false events promote feelings of recognition and familiarity, which in turn interfere with source attributions." - Amira

Albert Bandura on social learning, the origins of morality, and the impact of technological change on human nature
"Technology has changed the speed and the scope of social influence and has really transformed our realities. (...) I see that most of our learning is by social modeling and through indirect experiences. Errors can be very costly and you can’t afford to develop our values, our competences, our political systems, our religious systems through trial and error. Modeling shortcuts this process. (…) With new technologies, we’re essentially transcending our physical environment and more and more of our values and attitudes and behavior are now shaped in the symbolic environment – the symbolic environment is the big one rather than the actual one. The changes are so rapid that there are more and more areas of life now in which the cyber world is really essential. One model can affect millions of people worldwide, it can shape their experiences and behaviors. We don’t have to rely on trial and error. (...)" - Amira from Bookmarklet
"The revolutionary tendency of technology has increased our sense of agency. If I have access to all global knowledge, I would have fantastic capacities to educate myself. (…) The important thing in psychology is that we need a theory of human agency, rather than arguing that we’re controlled by neural networks. In every aspect of our lives we now have a greater capacity for exercicing agency." - Amira
We assume that aggression is inbred, but some societies are remarkably pacifistic. And we can also see large variations within a society. But the most striking example might be the transformation from warrior societies into peaceful societies. Switzerland is one example. Sweden is another: Those vikings were out mugging everyone and people would pray for protection: - Elestirel Gunluk

The general's ability to order people around is, paradoxically, a first step "in the direction of law."

"Lehrer executed one of the most bewildering recent journalistic frauds, one that on Monday cost him his prestigious post at the magazine and his status as one of the most promising, visible and well-paid writers in the business. An article in Tablet magazine revealed that in his best-selling book, “Imagine: How Creativity Works,” Mr. Lehrer had fabricated quotes from Bob Dylan, one of the most closely studied musicians alive. Only last month, Mr. Lehrer had publicly apologized for taking some of his previous work from The Wall Street Journal, Wired and other publications and recycling it in blog posts for The New Yorker, acts of recycling that his editor called “a mistake.” By Monday, when the Tablet article was published online, both The New Yorker and Mr. Lehrer’s publisher, Houghton Mifflin Harcourt, made it clear that they had lost patience with him." - Adriano from Bookmarklet

That’s the question underlying the work of the Institute for Centrifugal Research, where scientists believe that spinning people around at a sufficiently high G-force will solve “even the trickiest challenges confronting mankind.” (...)

Riders enter a round car that rises slowly up, up, up and then takes off suddenly at incredibly high speed along one of the “branches.” “Unpredictability is a key part of our work,” says Laslowicz. After the ride, he says, people described experiencing a “readjustment of key goals and life aspirations.” Though he later adds that he wouldn’t put his own children on one of his rides. “These machines provide total freedom,” Laslowicz says, “cutting all connection to the world we live in: communication responsibility, weight.

"Intelligence in the Human Machine,” the cello/brain duet, explored the relationship a performer has to the music she’s playing. During the performance, at Chicago’s Cultural Center, Kleijn wore an Emotiv EPOC, a neuroheadset with 14 sensors that attach to the scalp and detect brainwaves. In front of her, a laptop flashed a word and a few measures of music. She then played the music on her cello, interpreting the word onscreen. At the same time, her brainwaves, translated to audio, changed sounds as she reacted to the word.

They're homunculi, and this looks like a regress, but it's only a finite regress, because you take each of those in turn and you break it down into a group of stupider, more specialized homunculi, and you keep going until you arrive at parts that you can replace with a machine..." - Adriano from Bookmarklet

"Sex, we have been led to believe, is as natural as breathing. But in fact, contends British philosopher Alain de Botton, it is "close to rocket science in complexity." It's not only a powerful force, it's often contrary to many other things we care about. Sex inherently sets up conflicts within us. We crave sex with people we don't know or love. It makes us want to do things that seem immoral or degrading, like slapping someone or being tied up. We feel awkward asking the people we love for the sex acts we really want. There's no denying that sex has its sweaty charms, and in its most exquisite moments dissolves the isolation that embodied life imposes on us. But those moments are rare, the exception rather than the rule, says de Botton, founder of London's School of Life.

“What is needed is nothing less than a breakthrough in philosophy, a theory that explains how brains create explanations. (…) What distinguishes human brains from all other physical systems is qualitatively different from all other functionalities, and cannot be specified in the way that all other attributes of computer programs can be. It cannot be programmed by any of the techniques that suffice for writing any other type of program. Nor can it be achieved merely by improving their performance at tasks that they currently do perform, no matter by how much. Why? I call the core functionality in question creativity: the ability to produce new explanations.

Scientists at the University of California, Berkeley, have found that the brain is wired to put in order all the categories of objects and actions that we see.

"'The structure and content of thinking looks very much like the structure and content of dreaming. They may be the product of the same machine,' said Matthew Wilson, a neuroscientist at MIT and a panelist at the New York Academy of Sciences discussion 'The Strange Science of Sleep and Dreams' on Friday (Nov. 9). His work and others' explores the crucial link between dreams and learning and memory. Dreams allow the brain to work through its conscious experiences. During them, the brain appears to apply the same neurological machinery used during the day to examine the past, the future and other aspects of a person's (or animal's) inner world at night. Memory is the manifestation of this inner world, Wilson said. 'What we remember is the result of dreams rather than the other way around,'" he said. - Wynne Parry - Lit from Bookmarklet

"Spatial location is closely connected to the formation of new memories. Until now, grid cells were thought to be part of a single unified map system. New findings from the Norwegian University of Science and Technology demonstrate that the grid system is in fact composed of a number of independent grid maps, each with unique properties. Each map displays a particular resolution (mesh size), and responds independently to changes in the environment. A system of several distinct grid maps can support a large number of unique combinatorial codes used to associate new memories formed with specific spatial information. (...) Your brain has at least four different senses of location – and perhaps as many as 10. And each is different. (...) This independence can be used by the brain to create new combinations - many combinations - which is a very useful tool for memory formation. (...)" - Amira from Bookmarklet

It’s pretty easy to use trial and error when you’re dealing with only a few letters (e.g. “YOU”), but as soon as you’ve got 7, 8, or 9 letters to unscramble, trial and error could take you a very long time (e.g. “VERAUNTDE”).   You’ll need a heuristic such as “RE” often go together as do “A” and “D.”  Using such rules of English words, you’ll more easily and quickly arrive at the solution (“ADVENTURE”)." - Lit from Bookmarklet

He also explores why language is such a fundamental part of social relationships, human biology, and human evolution. Finally, Pinker touches on the wide variety of applications for linguistics, from improving how we teach reading and writing to how we interpret law, politics, and literature." - Amira from Bookmarklet

Borges and Memory: Encounters with the Human Brain | Scientific American
"What is the genesis of Funes the Memorious, the Jorge Luis Borges story about a mnemonist that fascinates neuroscientists, and is as famed a fictional treatise on memory as anything but Proust’s Remembrance of Things Past? (...) Funes the Memorious” tells the vicissitudes of Ireneo Funes, a peasant from Fray Bentos, who after falling off a horse and hitting his head hard recovers consciousness with the incredible skill—or perhaps curse—of remembering absolutely everything. (...) Borges again plays with the infinite in a context no less fascinating: the vast labyrinths of memory and the consequences of having an unlimited capacity to remember. (...)" - Amira from Bookmarklet
"Borges argues that “Funes the Memorious” is a long metaphor of insomnia. In fact, toward the end of the story he mentions that Funes found sleeping difficult, because to sleep is to get distracted from the world. Borges gives more details on the way he conceived Funes during his own sleepless nights. (...) Imagine the most extreme example, a human being who does not possess the power... more... - Amira

Jeff BEZOS ::  People who are right a lot of the time are people who often changed their minds . [via Jason Fried, 37signals]
"[Bezos] doesn’t think consistency of thought is a particularly positive trait. It’s perfectly healthy — encouraged, even — to have an idea tomorrow that contradicted your idea today. He’s observed that the smartest people are constantly revising their understanding, reconsidering a problem they thought they’d already solved. They’re open to new points of view, new information, new ideas, contradictions, and challenges to their own way of thinking. This doesn’t mean you shouldn’t have a well formed point of view, but it means you should consider your point of view as temporary. \\ What trait signified someone who was wrong a lot of the time? Someone obsessed with details that only support one point of view. If someone can’t climb out of the details, and see the bigger picture from multiple angles, they’re often wrong most of the time." - Adriano from Bookmarklet

tabloid version, "The Simulation Argument: Why the Probability that You Are Living in a Matrix is Quite High" http://www.simulation-argument.com/matrix... -- but ad infinitum, "if our universe were one of many being simulated, the simulation argument could therefore be statistically applied to the creators saying they are in a simulation." http://en.wikipedia.org/wiki... \\ Discuss wormhole: http://www.quora.com/How-wou... -- but the Dream Argument keeps it simple: "the mind's ability to create simulated realities during REM sleep affects the statistical likelihood of our own reality being simulated." - Adriano from Bookmarklet
most interesting XKCD http://xkcd.com/505/ got me thinking about a simulator based on a cellular automaton complex enough for combinatorial chemistry: http://ff.im/Xuncn to generate life itself -- but if it was merely Turing computable then human consciousness could have been simulated to imagine such things. On the other hand, you are unpredictable and computational irreducible: https://docs.google.com/viewer... -- really, is that how you think of yourself? - Adriano
Even if you're unpredictable and computationally irreducible, it doesn't mean you can be simmed. - Victor Ganata
it was a sleight of hand -- both hands are actually simmed :-) one could argue that the initial conditions are never known with sufficient precision, and that even if the computational process is deterministic (chaotic) the environment could introduce pseudo-random bits to throw us off from believing reducibility. - Adriano
Whoa, Dude, We are Inside a Computer Right Now... Rich Terrile, director at NASA Center for Evolutionary Computation: "The universe is pixelated—in time, space, volume, and energy. There exists a fundamental unit that you cannot break down into anything smaller, which means the universe is made of a finite number of these units. This also means there are a finite number of things the... more... - Adriano
Q: what would be the minimum clock speed of the computer simulating the universe? cf. http://www.quora.com/Physics... - Adriano
Man, there are way too many people in that thread completely stuck on the fact that clock speeds are in Hertz while the speed of light is in meters per second. They can't seem to make the jump to the fact that the properties of light literally dictate the maximum rate at which information can be transmitted. - Victor Ganata
Silas Beane discusses evidence of pixelation in terms of lattice spacing via Quantum Chromodynamics, "Constraints on the Universe as a Numerical Simulation" (2012) http://goo.gl/Gpo1f -- assuming the classical limit of a quantum computer, the lattice spacing should be non-zero if we are in a simulation, and orders of magnitude finer than Planck scale. (Think of a believable discretization of the Feynman-Kac path integral :-) - Adriano
good comments on the Beane paper, https://www.quora.com/Physics... "How is the vision of the universe as a computer simulation considered among modern physicists?" - Adriano

Eye-opener! publication bias practically constitutes research fraud... "When a new drug gets tested, the results of the trials should be published for the rest of the medical world -- except much of the time, negative or inconclusive findings go unreported, leaving doctors and researchers in the dark. In this impassioned talk, Ben Goldacre explains why these unreported instances of negative data are especially misleading and dangerous." - Adriano
