We’re All Tripping, All The Time…

Beau Lotto explains in his Ted Talk... ...and Ben Thomas interprets for Huffington Post:
The year was 1943, and the Pentagon had a problem. They'd poured millions of dollars into a new voice encryption system -- dubbed the "X System" -- but no one was certain how secure it was. So the top brass called in Claude Shannon to analyze their code and -- if all went well -- to prove that it was mathematically unbreakable. Shannon was a new breed of mathematician: A specialist in what's known today as information theory. To Shannon and his fellow theorists, information was something separate from the letters, numbers and facts it represented. Instead, it was something more abstract; more mathematical: in a word, it was non-redundancy...

Are Our Minds Really Confined To Our Brains?

Via Reality Sandwich, Rupert Sheldrake argues no:

Materialism is the doctrine that only matter is real. Hence minds are in brains, and mental activity is nothing but brain activity. This assumption conflicts with our own experience.

In his study of children’s intellectual development, the Swiss psychologist Jean Piaget found that before about the age of ten or eleven, European children were like “primitive” people. They did not know that the mind was confined to the head; they thought it extended into the world around them. But by about the age of eleven, most had assimilated what Piaget called the “correct” view.

But not all philosophers and psychologists believe the mind-in-the-brain theory, and over the years a minority has always recognized that our perceptions may be just where they seem to be, in the external world outside our heads, rather than representations inside our brains.

My own interpretation is that vision takes place through extended perceptual fields, which are both within the brain and stretch out beyond it.

Synesthesia May Explain Healers Claims of Seeing People’s ‘Aura’

Via ScienceDaily:
Researchers in Spain have found that at least some of the individuals claiming to see the so-called aura of people actually have the neuropsychological phenomenon known as "synesthesia" (specifically, "emotional synesthesia"). This might be a scientific explanation of their alleged ability. In synesthetes, the brain regions responsible for the processing of each type of sensory stimuli are intensely interconnected. Synesthetes can see or taste a sound, feel a taste, or associate people or letters with a particular color. The study was conducted by the University of Granada Department of Experimental Psychology Óscar Iborra, Luis Pastor and Emilio Gómez Milán, and has been published in the journal Consciousness and Cognition. This is the first time that a scientific explanation has been provided for the esoteric phenomenon of the aura, a supposed energy field of luminous radiation surrounding a person as a halo, which is imperceptible to most human beings...

Instead of Being Disgusted by Poverty, We are Disgusted by Poor People

Suzanne Moore writes at the Guardian:
She is there whenever I go the shops. Every time I think she can't get any more skeletal, she manages it. Wild eyes staring in different directions, she must have been pretty once. I try not to look, for she is often aggressive. Sometimes, though, she is in my face and asking me to go into the shop, from which she has been banned, to buy her something. A scratchcard. She feels lucky. "Maybe some food?" I suggest pointlessly, but food is not what she craves. Food is not crack. Or luck. She has already lost every lottery going. An addict is the author of their own misfortune. Her poverty is self-inflicted. All these hopeless people: where do they all come from? It is, of course, possible never to really see them, as their distress is so distressing. Who needs it? Poverty, we are often told, is not "actual", because people have TVs. This gradual erosion of empathy is the triumph of an economic climate in which everyone, addicted or not, is personally responsible for their own lack of achievement. Poor people are not simply people like us, but with less money: they are an entirely different species. Their poverty is a personal failing. They have let themselves go. This now applies not just to individuals but to entire countries. Look at the Greeks! What were they thinking with their pensions and minimum wage? That they were like us? Out of the flames, they are now told to rise, phoenix–like, by a rich political elite. Perhaps they can grow money on trees?

Europeans Decide Greece Is the Laziest, Most Incompetent Nation in the EU (Greece Disagrees!)

We invented Democracy (with a capital "D"). Writes Derek Thompson in the Atlantic:
Greece is the hardest-working country in the EU! According to Greece. And only Greece. According to Britain, Germany, Spain, Poland, and the Czech Republic, it's the laziest country in Europe. Meanwhile, Germany is the most respected EU country, according to the Pew Global report, European Unity on the Rocks. And Greece appears to be living in a bizarro universe where 78% of its respondents held negative views of Germany. Three in five Greeks said their country had Europe's hardest working citizens. Half of the rest of the respondents from the other seven nations said Greece had the laziest workforce in Europe...

Your Internal Clock Is At War With Society

SleepingAn interesting read for night owls and early birds alike. As Robert T. Gonzalez writes on io9.com:

Just because you sleep later than your early rising friends doesn’t mean you sleep longer than they do; nor does it make you lazier. And yet, the association between the time of day that a person wakes up and how proactive or driven they are is just one example of the many preconceptions that society upholds regarding sleep and productivity.

But here’s the problem: these expectations might actually be working against us.

In his recently published book, Internal time: Chronotypes, Social Jet Lag and Why You’re So Tired, German chronobiologist Till Roenneberg provides numerous examples of how social expectations surrounding time may be having a detrimental effect on large sections of the human population. Over on Brain Pickings, Maria Popova walks us through one of Roenneberg’s examples, wherein he examines the clash between adolescents’ sleep cycles and the starting times of typical school days…

Holding A Gun Makes You Think Others Are Too

2188722508_c8313a49fa_nWonder if this ever comes into play in real life? Via Science Blog:

Wielding a gun increases a person’s bias to see guns in the hands of others, new research from the University of Notre Dame shows. In five experiments, subjects were shown multiple images of people and determined whether the person was holding a gun or a neutral object such as a soda can or cell phone. Subjects did this while holding either a toy gun or a neutral object, such as a foam ball.

Simply showing observers a nearby gun did not influence their behavior; holding and using the gun was important. By virtue of affording the subject the opportunity to use a gun, he or she was more likely to classify objects in a scene as a gun and, as a result, to engage in threat-induced behavior, such as raising a firearm to shoot.

“Now we know that a person’s ability to act in certain ways can bias their recognition of objects as well, and in dramatic ways.
