The fact that many of our self-protective delusions are built into the way the brain works is no justification for not trying to override them. Knowing how dissonance works helps us identify our own inclinations to perpetuate errors -- and protect ourselves from those who can’t. Or won’t.Related LinksWhat Historians Can Learn from the Social Sciences and Sciences /* * * CONFIGURATION VARIABLES: EDIT BEFORE PASTING INTO YOUR WEBPAGE * * */ var disqus_shortname = 'hnndev'; // required: replace example with your forum shortname /* * * DON'T EDIT BELOW THIS LINE * * */ (function() { var dsq = document.createElement('script'); dsq.type = 'text/javascript'; dsq.async = true; dsq.src = '//' + disqus_shortname + '.disqus.com/embed.js'; (document.getElementsByTagName('head')[0] || document.getElementsByTagName('body')[0]).appendChild(dsq); })(); Please enable JavaScript to view the comments powered by Disqus.

at last, history has gotten into bed with psychological science, and it’s a happy match. History gives us the data of, in Barbara Tuchman’s splendid words, our march of folly -- repeated examples of human beings unable and unwilling to learn from mistakes, let alone to admit them. Cognitive science shows us why

Our brains, which have allowed us to travel into outer space, have a whole bunch of design flaws, which is why we have so much breathtaking bumbling here on Earth.

The popular left/right story has no solid basis in science. The brain doesn't work one part at a time, but rather as a single interactive system, with all parts contributing in concert, as neuroscientists have long known. The left brain/right brain story may be the mother of all urban legends: It sounds good and seems to make sense—but just isn't true.

There is a better way to understand the functioning of the brain, based on another, ordinarily overlooked anatomical division—between its top and bottom parts. We call this approach "the theory of cognitive modes." Built on decades of unimpeachable research that has largely remained inside scientific circles, it offers a new way of viewing thought and behavior

Our theory has emerged from the field of neuropsychology, the study of higher cognitive functioning—thoughts, wishes, hopes, desires and all other aspects of mental life. Higher cognitive functioning is seated in the cerebral cortex, the rind-like outer layer of the brain that consists of four lobes

Although previous work had indirectly suggested that changing mitochondrial function affected lifespan, “this is the first clear demonstration [that it] extends mouse lifespan,” Miller added.

well known that mitochondria are linked to health. Some evidence suggests that inhibiting mitochondrial function can be harmful—as in the case of diabetes or obesity—but earlier data from nematodes and fruit flies also suggest a link to lifespan increase. The latest findings are a step toward untangling one of the current debates in the field—whether inhibiting mitochondrial function is detrimental or beneficial,

The average lifespan of BXD mice range from 1 year to almost 2.5 years. The researchers were able to link 3 genes to longevity variability, including mitochondrial ribosomal protein S5 (Mrps5), which encodes a protein integral to mitochondrial protein synthesis. They found that BXD strains with 50 percent less Mrps5 expression lived about 250 days longer than BXD mice with more robust Mrps5 expression.

any ability resulting from practice and cultivation could accurately be said to embody kung fu.

the predominant orientation of traditional Chinese philosophy is the concern about how to live one’s life, rather than finding out the truth about reality.

Confucius’s call for “rectification of names” — one must use words appropriately — is more a kung fu method for securing sociopolitical order than for capturing the essence of things, as “names,” or words, are placeholders for expectations of how the bearer of the names should behave and be treated. This points to a realization of what J. L. Austin calls the “performative” function of language.

The public middle school, which is part of a larger complex that includes Corona del Mar High School, now is attracting more students who would normally have gone to private school in this affluent Orange County district, said Principal Rebecca Gogel. “There has been a significant change in student behavior,” she said.

But what has gone into the design of this school goes much deeper than sheer aesthetics. Architects are now applying neuroscience to design schools, hospitals, community centers and even single-family homes.

meshing of architecture and brain science is starting to gain traction. Architects are studying the way the brain reacts to various environments through brain scanners and applying the findings to their designs.

If stress is controlled by these few cortical areas—the part of the brain that deals in high-level executive functioning, our beliefs and existential understandings of ourselves—why would any sort of body movement play a part in decreasing stress?

Pittsburgh neuroscientists showed that they have discovered a discrete, elaborate network in the cerebral cortex that controls the adrenal medulla. It seems that the connections between the brain and the adrenal medulla are much more elaborate than previously understood. Complex networks throughout the primary sensory and motor cortices are tied directly to our stress responses.

“This is suggesting a much more decentralized process,” said Bruno of the findings. He was not involved in the study.“You have lots of different circuits built on top of one another, and they’re all feeding back to one of our most primitive and primordial response systems. They've really shown that stress is controlled by more than the traditional high-level cognitive areas. I think that’s a big deal.

“I think I can safely say that nobody really understands quantum mechanics,” observed the physicist and Nobel laureate Richard Feynman.

What’s surprising is that physicists seem to be O.K. with not understanding the most important theory they have.

Scientists can use quantum mechanics with perfect confidence. But it’s a black box. We can set up a physical situation, and make predictions about what will happen next that are verified to spectacular accuracy. What we don’t do is claim to understand quantum mechanics

Predictive statistical analysis, harnessed to big data, appears poised to alter the way millions of people are hired and assessed.

By one estimate, more than 98&nbsp;percent of the world’s information is now stored digitally, and the volume of that data has quadrupled since 2007.

The application of predictive analytics to people’s careers—an emerging field sometimes called “people analytics”—is enormously challenging, not to mention ethically fraught

Early in the pandemic, people with COVID-19 began reporting an odd symptom: the loss of smell and taste.

Their fears proved well-founded — though the damage may come from the body and brain's response to the virus rather than the virus itself.

Many patients who are hospitalized for COVID-19 are discharged with symptoms such as those associated with a brain injury. These include "forgetfulness that impairs their ability to function,"

Meltdowns, common as they are among young children, are a complicated physiological response related to the brain’s threat detection system. Mid-freakout, it’s helpful for parents to understand what’s going on beneath the surface, then to mitigate the “threat” by establishing a sense of safety.

temper tantrum involves two parts of the brain: the amygdala, which is primarily responsible for processing emotions like fear or anger; and the hypothalamus, which in part controls unconscious functions like heart rate or temperature.

“When you have a fire burning in your house, you don’t want to sit and ponder, you want your body to fire on all cylinders so you can escape,”

A variety of methods have been developed over the past few decades to allow mapping of the functioning human brain. Two basic classes of mapping technique have evolved: those that map (or localise) the underlying electrical activity of the brain; and those that map local physiological or metabolic consequences of altered brain electrical activity. Among the former are the non-invasive neural electromagnetic techniques of electroencephalography (EEG) and magnetoencephalography (MEG). These methods allow exquisite temporal resolution of neural processes (typically over a 10–100 ms time scale), but suffer from poor spatial resolution (between 1 and several centimetres). Functional MRI (fMRI) methods are in the second category. They can be made sensitive to the changes in regional blood perfusion, blood volume (for example, using injected magnetic resonance contrast agents), or blood oxygenation that accompany neuronal activity. Blood oxygenation level dependent (BOLD) fMRI, which is sensitive primarily to the last of these variables, allows an image spatial resolution that is of the order of a few millimetres, with a temporal resolution of a few seconds (limited by the haemodynamic response itself). An accessible and more detailed introduction to the technique than is possible in this brief review is found in a recent book.1

Methods such as positron emission tomography (PET) provide an absolute measure of tissue metabolism. In contrast, BOLD fMRI can at present be used only for determining relative signal intensity changes associated with different cognitive states during a single imaging session. The most time efficient approach for comparing brain responses in different states during the imaging experiment is the “block” design19 (fig 3). This design uses relatively long alternating periods (for example, 30 seconds), during each of which a discrete cognitive state is maintained. In the simplest form, there may only be two such states, which are alternated throughout the experiment in order to ensure that variations arising from fluctuations in scanner sensitivity, patient movement, or changes in attention have a similar impact on the signal responses associated with both states.

the pace of improvement in technology would become a runaway phenomenon that would transform all aspects of human civilization.

the structure and functioning of the human brain is actually quite simple, a basic unit of cognition repeated millions of times. Therefore,&nbsp;creating an artificial brain will not require simulating the human brain at every level of detail. It will only require reverse engineering this basic repeating unit.

The bank experience showed how you could be oppressed by hierarchy, working in an environment where you were neither free nor equal. But this implied that freedom and equality were bound together in some way beyond the basic state of being unenslaved, which was an unorthodox notion. Much social thought is rooted in the idea of a conflict between the two.

If individuals exercise freedoms, conservatives like to say, some inequalities will naturally result. Those on the left basically agree—and thus allow constraints on personal freedom in order to reduce inequality. The philosopher Isaiah Berlin called the opposition between equality and freedom an “intrinsic, irremovable element in human life.” It is our fate as a society, he believed, to haggle toward a balance between them.

What if they weren’t opposed, Anderson wondered, but, like the sugar-phosphate chains in DNA, interlaced in a structure that we might not yet understand?

Theo and Robin have a nightly ritual where they say a prayer that Alyssa, the deceased wife and mother, taught them: May all sentient beings be free from needless suffering. That prayer itself comes from the four immeasurables in the Buddhist tradition.

When we enter into or recover this sense of kinship that was absolutely fundamental to so many indigenous cultures everywhere around the world at many, many different points in history, that there is no radical break between us and our kin, that even consciousness is shared, to some degree and to a large degree, with a lot of other creatures, then death stops seeming like the enemy and it starts seeming like one of the most ingenious kinds of design for keeping evolution circulating and keeping the experiment running and recombining.

Look, I’m 64 years old. I can remember sitting in psychology class as an undergraduate and having my professor declare that no, of course animals don’t have emotions because they don’t have an internal life. They don’t have conscious awareness. And so what looks to you like your dog being extremely happy or being extremely guilty, which dogs do so beautifully, is just your projection, your anthropomorphizing of those other creatures. And this prohibition against anthropomorphism created an artificial gulf between even those animals that are ridiculously near of kin to us, genetically.

By Scientism, I mean three interrelated ideas that, taken together, stand as one of the pillars of Technopoly.

The first and indispensable idea is, as noted, that the methods of the natural sciences can be applied to the study of human behavior. This idea is the backbone of much of psychology and sociology as practiced at least in America, and largely accounts for the fact that social science, to quote F. A. Hayek, "has cont~ibuted scarcely anything to our understanding of social phenomena." 2

The second idea is, as also noted, that social science generates specific principles which can be used to organize society on a rational and humane basis. This implies that technical meansmostly "invisible technologies" supervised by experts-can be designed to control human behavior and set it on the proper course.

Slow transit constipation (STC) is a common disease characterized by markedly delayed colonic transit time as a result of colonic motility dysfunction. It is well established that STC is mostly caused by disorders of relevant nerves, especially the enteric nervous system (ENS).

After 5 weeks of treatment, CES could enhance the colonic electromyogram (EMG) signal to promote colonic motility, thereby improving the colonic content emptying of STC beagles. HE staining and transmission electron microscopy confirmed that CES could regenerate ganglia and synaptic vesicles in the myenteric plexus.

Taken together, pulse train CES could induce the regeneration of myenteric plexus neurons, thereby promoting the colonic motility in STC beagles.

mindfulness is less about spirituality and more about concentration: the ability to quiet your mind, focus your attention on the present, and dismiss any distractions that come your way. The formulation dates from the work of the psychologist Ellen Langer, who demonstrated in the 1970s that mindful thought could lead to improvements on measures of cognitive function and even vital functions in older adults.

Even in small doses, mindfulness can effect impressive changes in how we feel and think — and it does so at a basic neural level.

In 2011, researchers from the University of Wisconsin demonstrated that daily meditation-like thought could shift frontal brain activity toward a pattern that is associated with what cognitive scientists call positive, approach-oriented emotional states — states that make us more likely to engage the world rather than to withdraw from it.

the method outlined in Kondo’s book. It includes something called a “once-in-a-lifetime tidying marathon,” which means piling five categories of material possessions — clothing, books, papers, miscellaneous items and sentimental items, including photos, in that order — one at a time, surveying how much of each you have, seeing that it’s way too much and then holding each item to see if it sparks joy in your body. The ones that spark joy get to stay. The ones that don’t get a heartfelt and generous goodbye, via actual verbal communication, and are then sent on their way to their next life.
