The World's Largest Hedge Fund Is Building an Algorithmic Model of Its Founder's Brain - "Mr. Dalio has the highest stratum score at Bridgewater, and the firm has told employees he has one of the highest in the world. Likewise, Bridgewater's software judges Mr. Dalio the firm's most 'believable' employee in matters such as investing and leadership, which means his opinions carry more weight. Mr. Dalio is always in search of new data with which to measure his staff. He once raised the idea of using head bands to track people's brain waves, according to one former employee. The idea wasn't adopted." [more inside]
How big data increases inequality and threatens democracy - "A former academic mathematician and ex-hedge fund quant exposes flaws in how information is used to assess everything from creditworthiness to policing tactics, with results that cause damage both financially and to the fabric of society. Programmed biases and a lack of feedback are among the concerns behind the clever and apt title of Cathy O'Neil's book: Weapons of Math Destruction." [more inside]

World After Capital by Albert Wenger [Work in Progress; GitHub; GitBook; PDF; FAQ] - "Technological progress has shifted scarcity for humanity. When we were foragers, food was scarce. During the agrarian age, it was land. Following the industrial revolution, capital became scarce. With digital technologies scarcity is shifting from capital to attention. World After Capital suggests ways to expand economic, informational and psychological freedom to go from an industrial to a knowledge society." (previously)

"I’ve been infected by a parasite. I won’t tell you what because I don’t want you to search for it. By the time this reaches you it won’t matter much, anyway. In fact, I’m forbidding you right now from looking for anything or asking anyone. Apparently I have about twelve hours as myself. They won’t say what happens next, because it’s kind of unpredictable. There are lots of animals who’ve had it, but only two people. They won’t tell me." -- The Glad Hosts, a SF short story by Rebecca Campbell
Facebook's bias training: "There are different forms of unconscious bias that can prevent us from cultivating an inclusive and innovative workplace. In these videos, we discuss four common types of biases: Performance Bias, Performance Attribution Bias, Competence/Likeability Trade-off Bias, and Maternal Bias."
"Humans as Superorganisms: How Microbes, Viruses, Imprinted Genes and Other Selfish Entities Shape Our Behavior" by Peter Kramer and Paola Bressan discusses the idea that an individual homo sapiens is only one component of the human superorganism we call a person, focusing on the psychological and psychiatric ramifications thereof. (Paola Bressan previously.)
Teachers and administrators still rely overwhelmingly on outdated systems of reward and punishment, using everything from red-yellow-green cards, behavior charts, and prizes to suspensions and expulsions. [... ] But consequences have consequences. Contemporary psychological studies suggest that, far from resolving children's behavior problems, these standard disciplinary methods often exacerbate them. They sacrifice long-term goals (student behavior improving for good) for short-term gain—momentary peace in the classroom. What If Everything You Knew About Disciplining Kids Was Wrong?
It's common to frame ecology as a science that gets practiced in wild, untraveled areas. But cities have an ecology all their own, and the design of a given city contributes to the diversity of animals that make their homes there. Rats are particularly good at navigating cities, but other species might have a tougher time getting around.
Pfft. . . A real man just craps his pants and asks if anyone has a problem with it.

China rates its own citizens - including online behaviour: "The Chinese government is currently implementing a nationwide electronic system, called the Social Credit System, attributing to each of its 1,3 billion citizens a score for his or her behavior. The system will be based on various criteria, ranging from financial credibility and criminal record to social media behavior. From 2020 onwards each adult citizen should, besides his identity card, have such a credit code." [more inside]

"It was always assumed that V-formation flight was learned from the adult birds. But these guys are all the same age and they learned to fly from a human in a microlight. They learned V-formation flying from each other. National Geographic reports on some of the fascinating intricacies of the V formation observed in migrating birds.
Your body is home to about 100 trillion bacteria and other microbes, collectively known as your microbiome. Naturalists first became aware of our invisible lodgers in the 1600s, but it wasn’t until the past few years that we’ve become really familiar with them. This recent research has given the microbiome a cuddly kind of fame. We’ve come to appreciate how beneficial our microbes are — breaking down our food, fighting off infections and nurturing our immune system. It’s a lovely, invisible garden we should be tending for our own well-being. But in the journal Bioessays, a team of scientists has raised a creepier possibility. Perhaps our menagerie of germs is also influencing our behavior in order to advance its own evolutionary success — giving us cravings for certain foods, for example.[more inside]
Finding out that the gorillas, badgers, giraffes, belugas, or wallabies on the other side of the glass are taking Valium, Prozac, or antipsychotics to deal with their lives as display animals is not exactly heartwarming news.

The approximate moment when grumpiness kicks in for men is around age 70. Researchers found that as men grow older — from, say, 50 on — they have fewer obstacles and annoyances to worry about in life and, furthermore, they are more equipped to deal with adversity. But around age 70, life — or at least the perception of happiness — begins to go downhill. [more inside]
Dennis Hlynsky is a professor of film and animation at RISD whose most recent work, titled Small Brains on Mass, looks at bird behavior, particularly how they interact when flying in groups. To better understand how flying as a flock is achieved, Hlynsky filmed the birds and then stacked the images on the same frame for a set number of frames, the results show each bird’s flight as a trail, but synchronized with the flock. The results are often pure poetry. [more inside]

“I don’t think you’re gay,” he said. He then went through the same litany as Dr. F.—he didn’t believe I was a pervert, he just felt I was lost and confused and needed to be set on the right path. Dr. K. believed in behavioral modification. He told me to place a rubber band around my wrist. Every time I had “gay thoughts,” I was to snap the rubber band, causing pain. Eventually I would associate the thoughts with the pain. - Gene Stone on growing up gay, struggling with sex, anti-gay conversion therapy, and the doctor-mandated sex surrogate that finally helped him.

"After she passed, the chimps examined the body, inspecting Pansy’s mouth, pulling her arm and leaning their faces close to hers. Blossom sat by Pansy’s body through the night. And when she finally moved away to sleep in a different part of the enclosure, she did so fitfully, waking and repositioning herself dozens more times than was normal. For five days after Pansy’s death, none of the other chimps would sleep on the platform where she died."— "Want to Understand Mortality?

"Maybe it's a sore point: your field should have an answer (people think you do) but there isn't one yet. Perhaps it's simple to pose but hard to answer. Or it's a question that belies a deep misunderstanding: the best answer is to question the question."
Is Psychometric g a Myth? - "As an online discussion about IQ or general intelligence grows longer, the probability of someone linking to statistician Cosma Shalizi's essay g, a Statistical Myth approaches 1.

Sian Jarvis, the supermarket’s head of corporate affairs, had undermined her claims to care about the health of her customers and let slip one of the secrets of a multi-billion-pound industry ... she revealed that one in three Asda checkouts “are what we call guilt-free checkouts”. Jarvis insisted “guilt-free” was merely “a term that’s commonly used in retail”. But it was too late, and her “guilt” gaffe quickly invited scorn in the industry and among public health professionals. Whatever the damage, she had already opened a door to the arcane science of supermarket psychology. To the designers of the modern store, shoppers are lab rats with trolleys, guided through a maze of aisles by the promise of rewards they never knew they sought The Secrets Of Our Supermarkets[more inside]
Deciphering the Tools of Nature’s Zombies: The ability of parasites to alter the behaviour of their hosts fascinates both scientists and non-scientists alike. One reason that this topic resonates with so many is that it touches on core philosophical issues such as the existence of free will. If the mind is merely a machine, then it can be controlled by any entity that understands the code and has access to the machinery. This special issue of The Journal of Experimental Biology highlights some of the best-understood examples of parasite-induced changes in host brain and behaviour, encompassing both invertebrate and vertebrate hosts and micro- and macro-parasites.

From the mid 40s to the mid 50s Coronet Instructional Films were always ready to provide social guidance for teenagers on subjects as diverse as dating, popularity, preparing for being drafted, and shyness, as well as to children on following the law, the value of quietness in school, and appreciating our parents. They also provided education on topics such as the connection between attitudes and health, what kind of people live in America, how to keep a job, supervising women workers, the nature of capitalism, and the plantation System in Southern life. Inside is an annotated collection of all 86 of the complete Coronet films in the Prelinger Archives as well as a few more. Its not like you had work to do or anything right? [more inside]

A chronic public health disaster. Complex trauma and toxic stress puts children into a state of reflexive fight, flight, or freeze responses to a perpetually threatening world. The traditional authoritative response only serves to reinforce those behaviours and, perhaps worse, has long-term health consequences:
With an ACE score of 4 or more, things start getting serious. The likelihood of chronic pulmonary lung disease increases 390 percent; hepatitis, 240 percent; depression 460 percent; suicide, 1,220 percent.One doctor describes it as “a chronic public health disaster”. Remediating this problem is going to require listening, kindness, and parachutes.
