Unethical amnesia

From Kouchaki and Gino:

Despite our optimistic belief that we would behave honestly when facing the temptation to act unethically, we often cross ethical boundaries. This paper explores one possibility of why people engage in unethical behavior over time by suggesting that their memory for their past unethical actions is impaired. We propose that, after engaging in unethical behavior, individuals’ memories of their actions become more obfuscated over time because of the psychological distress and discomfort such misdeeds cause. In nine studies (n = 2,109), we show that engaging in unethical behavior produces changes in memory so that memories of unethical actions gradually become less clear and vivid than memories of ethical actions or other types of actions that are either positive or negative in valence. We term this memory obfuscation of one’s unethical acts over time “unethical amnesia.” Because of unethical amnesia, people are more likely to act dishonestly repeatedly over time.

The attention economy

I pass on some clips from an essay by Tom Chatfield:

How many other things are you doing right now while you’re reading this piece? Are you also checking your email, glancing at your Twitter feed, and updating your Facebook page? What five years ago David Foster Wallace labelled ‘Total Noise’ — ‘the seething static of every particular thing and experience, and one’s total freedom of infinite choice about what to choose to attend to’ — is today just part of the texture of living on a planet that will, by next year, boast one mobile phone for each of its seven billion inhabitants. We are all amateur attention economists, hoarding and bartering our moments…

Much as corporations incrementally improve the taste, texture and sheer enticement of food and drink by measuring how hard it is to stop eating and drinking them, the actions of every individual online are fed back into measures where moreinexorably means better: more readers, more viewers, more exposure, more influence, more ads, more opportunities to unfurl the integrated apparatus of gathering and selling data. Attention, thus conceived, is an inert and finite resource, like oil or gold: a tradable asset that the wise manipulator auctions off to the highest bidder, or speculates upon to lucrative effect. There has even been talk of the world reaching ‘peak attention’, by analogy to peak oil production, meaning the moment at which there is no more spare attention left to spend.

There’s a reductive exaltation in defining attention as the contents of a global reservoir, slopping interchangeably between the brains of every human being alive. Where is the space, here, for the idea of attention as a mutual construction more akin to empathy than budgetary expenditure — or for those unregistered moments in which we attend to ourselves, to the space around us, or to nothing at all?

From the loftiest perspective of all, information itself is pulling the strings: free-ranging memes whose ‘purposes’ are pure self-propagation, and whose frantic evolution outstrips all retrospective accounts…consider yourself as interchangeable as the button you’re clicking, as automated as the systems in which you’re implicated. Seen from such a height, you signify nothing beyond your recorded actions…in making our attentiveness a fungible asset, we’re not so much conjuring currency out of thin air as chronically undervaluing our time.

We watch a 30-second ad in exchange for a video; we solicit a friend’s endorsement; we freely pour sentence after sentence, hour after hour, into status updates and stock responses. None of this depletes our bank balances. Yet its cumulative cost, while hard to quantify, affects many of those things we hope to put at the heart of a happy life: rich relationships, rewarding leisure, meaningful work, peace of mind.

What kind of attention do we deserve from those around us, or owe to them in return? What kind of attention do we ourselves deserve, or need, if we are to be ‘us’ in the fullest possible sense? These aren’t questions that even the most finely tuned popularity contest can resolve. Yet, if contentment and a sense of control are partial measures of success, many of us are selling ourselves far too cheap.

A redefinition of health and well-being for older adults

McClintock et al. take a more comprehensive approach to defining health and find some interesting new categories. The healthiest people are obese and robust!

Significance

Health has long been conceived as not just the absence of disease but also the presence of physical, psychological, and social well-being. Nonetheless, the traditional medical model focuses on specific organ system diseases. This representative study of US older adults living in their homes amassed not only comprehensive medical information but also psychological and social data and measured sensory function and mobility, all key factors for independent living and a gratifying life. This comprehensive model revealed six unique health classes, predicting mortality/incapacity. The healthiest people were obese and robust; two new classes, with twice the mortality/incapacity, were people with healed broken bones or poor mental health. This approach provides an empirical method for broadly reconceptualizing health, which may inform health policy.

Abstract

The World Health Organization (WHO) defines health as a “state of complete physical, mental and social well-being and not merely the absence of disease or infirmity.” Despite general acceptance of this comprehensive definition, there has been little rigorous scientific attempt to use it to measure and assess population health. Instead, the dominant model of health is a disease-centered Medical Model (MM), which actively ignores many relevant domains. In contrast to the MM, we approach this issue through a Comprehensive Model (CM) of health consistent with the WHO definition, giving statistically equal consideration to multiple health domains, including medical, physical, psychological, functional, and sensory measures. We apply a data-driven latent class analysis (LCA) to model 54 specific health variables from the National Social Life, Health, and Aging Project (NSHAP), a nationally representative sample of US community-dwelling older adults. We first apply the LCA to the MM, identifying five health classes differentiated primarily by having diabetes and hypertension. The CM identifies a broader range of six health classes, including two “emergent” classes completely obscured by the MM. We find that specific medical diagnoses (cancer and hypertension) and health behaviors (smoking) are far less important than mental health (loneliness), sensory function (hearing), mobility, and bone fractures in defining vulnerable health classes. Although the MM places two-thirds of the US population into “robust health” classes, the CM reveals that one-half belong to less healthy classes, independently associated with higher mortality. This reconceptualization has important implications for medical care delivery, preventive health practices, and resource allocation.

Why do we feel awe?

I want to point to an article by Dacher Keltner on the functions of awe that appeared on the Slate website, along with others sponsored by the John Templeton Foundation. Here are clips describing a few of the experiments he mentions.

A new science is now asking “Why awe?” This is a question we can approach in two ways. First we can consider the long, evolutionary view: Why did awe became part of our species’ emotional repertoire during seven million years of hominid evolution? A preliminary answer is that awe binds us to social collectives and enables us to act in more collaborative ways that enable strong groups, thus improving our odds for survival.

For example, in one study from our Berkeley lab, my colleague Michelle Shiota had participants fill in the blank of the following phrase: “ I AM ____.” They did so 20 times, either while standing before an awe-inspiring replica of a T. rex skeleton in UC Berkeley’s Museum of Paleontology or in the exact same place but oriented to look down a hallway, away from the T. rex. Those looking at the dinosaur were more likely to define their individual selves in collectivist terms—as a member of a culture, a species, a university, a moral cause. Awe embeds the individual self in a social identity.

Near Berkeley’s Museum of Paleontology stands a grove of eucalyptus trees, the tallest in North America. When you gaze up at these trees, with their peeling bark and surrounding nimbus of grayish green light, goosebumps may ripple down your neck, a sure sign of awe...my colleague Paul Piff staged a minor accident near that grove to see if awe would prompt greater kindness...Participants first either looked up into the tall trees for one minute—long enough for them to report being filled with awe—or oriented 90 degrees away to look up at the facade of a large science building. They then encountered a person who stumbled, dropping a handful of pens into the dirt. Sure enough, the participants who had been gazing up at the awe-inspiring trees picked up more pens. Experiencing awe seemed to make them more inclined to help someone in need. They also reported feeling less entitled and self-important than the other study participants did.

Is humanity getting better?

I want to pass on a few clips from a stimulating essay by Leif Wenar, who suggests "The real trick to understanding our world is to see it with both eyes at once. The world now is a thoroughly awful place — compared with what it should be. But not compared with what it was. Keeping both eyes open gives depth to our perception of our own time in history, and makes us better able to see where paths to more progress may be open.":

The 20th century marked an inflection point — the beginning of humanity’s transition from its ancient crises of ignorance to its modern crises of invention. Our science is now so penetrating, our systems are so robust, that we are mostly endangered by our own creations...Our transportation networks are now so fast and far-flung that they transmit diseases worldwide before cures can catch up. The next epidemics will play on our strengths, not our weaknesses — fighting them will mean canceling flights, not killing fleas. This Horseman of the Apocalypse has dismounted and now travels coach.

Indeed, our machines have multiplied so much that a new crisis looms because of the smoke coming off them as they combust. Future food crises, if they come, will be driven by anthropogenic climate change. Famine will descend not from the wrath of God but from the growth of gross domestic product. We ourselves are outfitting the Horsemen of the future, or perhaps it’s better to say that we are creating them...Whether humans can overcome their coming crises of invention will turn on the philosopher’s old question of whether individuals are essentially good or evil, which is a hard question — but recent news will tempt many thumbs to turn downward.

A more positive answer emerges if we switch to a systems perspective, evaluating humanity as a whole as we would an ecosystem or a complex machine. What happens when humanity “adds” energy to itself ... as it’s done massively in the transition from wood and muscle power to fossil fuels and alternatives?..Something is happening to our species, and especially over the last 70 years. The years since 1945 have seen many horrors...Yet this has also been the most prosperous time in human history by far. And by a long way the time with the greatest increase in democracy around the world. It has also been the most peaceful era in recorded human history. As Joshua Goldstein puts it in “Winning the War on War,” “We have avoided nuclear wars, left behind world war, nearly extinguished interstate war, and reduced civil wars to fewer countries with fewer casualties.” Goldstein continues:

In the first half of the twentieth century, world wars killed tens of millions and left whole continents in ruins. In the second half of that century, during the Cold War, proxy wars killed millions, and the world feared a nuclear war that could have wiped out our species. Now, in the early twenty-first century, the worst wars, such as Iraq, kill hundreds of thousands. We fear terrorist attacks that could destroy a city, but not life on the planet. The fatalities still represent a large number and the impacts of wars are still catastrophic for those caught in them, but overall, war has diminished dramatically.

...the big picture of postwar history shows significant improvements in nearly all indicators of lived human experience. The average life span of humans is today longer than it has ever been. A smaller proportion of women die in childbirth than ever before. Child malnutrition is at its lowest level ever, while literacy rates worldwide have never been higher. Most impressive has been the recent reduction in severe poverty — the reduction in the percentage of humans living each day on what a tall Starbucks coffee costs in America. During a recent 20-year stretch the mainstream estimate is that the percentage of the developing world living in such extreme poverty shrank by more than half, from 43 to 21 percent.

Humanity does learn, painfully and often only after thousands or even millions have died ...humanity learns as identities alter to become less aggressive and more open, so that networks can connect individual capacities more effectively and join our resources together.

What we take for granted frames the size of our concerns. We’ve come to expect that mayors and police chiefs will not endorse, much less order, the lynching of minorities. Within that frame, racial profiling and deaths in police custody are top priorities. After decades, we’ve come to expect enduring peace among the great powers. Within that frame any military action by a major power, or a civil war in a resource-rich state, rightly becomes top news.

We can’t relax; the upward trends in time’s graphs may crest at any point. Yet batting away the positive facts is lazy, and requires only a lower form of intelligence.

Telephone metadata does reveal personal details.

Susan Landau reviews work of Mayer et al. that shows President Obama's statement:

When it comes to telephone calls, nobody is listening to your telephone calls. That’s not what this program is about. As was indicated, what the intelligence community is doing is looking at phone numbers and durations of calls. They are not looking at people’s names, and they’re not looking at content.

...is misleading. Mayer et al. convincingly show that call detail records (CDRs) are personally revelatory...

...it can be determined that someone is suffering from a multiple sclerosis relapse, having cardiac arrhythmia problems, seeking to buy an automatic rifle, intending to start a marijuana-growing venture, or having an abortion.

Needless to say, such insight puts communications surveillance law even more in flux. Here is the abstract from Mayer et al:

Since 2013, a stream of disclosures has prompted reconsideration of surveillance law and policy. One of the most controversial principles, both in the United States and abroad, is that communications metadata receives substantially less protection than communications content. Several nations currently collect telephone metadata in bulk, including on their own citizens. In this paper, we attempt to shed light on the privacy properties of telephone metadata. Using a crowdsourcing methodology, we demonstrate that telephone metadata is densely interconnected, can trivially be reidentified, and can be used to draw sensitive inferences.

A science of consciousness carnival in Tucson.

I started teaching my Biology of Mind course at the University of Wisconsin in the early 1990's, and was inspired and stimulated by attending the first of the "Towards a Science of Consciousness" meetings in Tucson, Az. There I met Daniel Dennett, who was very encouraging about my starting my book "The Biology of Mind" which was published in 1999. I attended the following two meetings but then dropped out as pseudoscience, wild speculation about quantum mechanics and consciousness, and New Age gibble-gabble continued make up a substantial fraction of the program. Fewer serious scientists were attending. George Johnson's review of the most recent meeting (now called "The Science of Consciousness," with the original organizer Stuart Hameroff presiding) makes me secure in my decision to have stayed away recently. Some clips from his review:

...wild speculations and carnivalesque pseudoscience were juxtaposed with sober sessions like “Agency and Mental Causation” and data-filled talks about probing conscious brain states with PET scans and EEGs...

...I found myself sitting, late one afternoon, in “Vibrations, Scale, and Topology,” where a musician from Tulsa, Okla., who called himself Timbre Wolf...played a recording of an eerie composition called “Brain Dance,” derived from vibrations generated by tiny molecular structures called microtubules, which are part of the scaffolding of brain cells. The music, to his ear, was reminiscent of Philip Glass, Steve Reich, Cuban rumba, Gustav Holst’s “The Planets,” and the visual rhythms of strange mathematical objects called Penrose tiles...All of this, he suspected, had something to do with quantum mechanics and consciousness, an idea that Dr. Hameroff has long been pursuing.

More disconcerting was the starring role given to the New Age entrepreneur Deepak Chopra. Dr. Chopra believes that human consciousness (through epigenetic feedback) directs the unfolding of human evolution.

No one seemed to object as Dr. Chopra, whose Chopra Foundation was one of the sponsors, shared the stage with prominent professors who engaged with his ideas as if he were another esteemed colleague....Also included in the lineup were presentations hypothesizing that dark energy could explain consciousness and that homeopathic medicine might work through nanoparticles and quantum entanglement — as if homeopathy worked at all.

Sentiments on cynicism and hope.

I want to pass on these clips from a commencement talk given by Maria Popova:

…in every environment densely populated by peers — self-comparison becomes inevitable.….here’s the thing about self-comparison: In addition to making you vacate your own experience, your own soul, your own life, in its extreme it breeds resignation. If we constantly feel that there is something more to be had — something that’s available to those with a certain advantage in life, but which remains out of reach for us — we come to feel helpless. And the most toxic byproduct of this helpless resignation is cynicism — that terrible habit of mind and orientation of spirit in which, out of hopelessness for our own situation, we grow embittered about how things are and about what’s possible in the world. Cynicism is a poverty of curiosity and imagination and ambition.

Today, the soul is in dire need of stewardship and protection from cynicism. The best defense against it is vigorous, intelligent, sincere hope — not blind optimism, because that too is a form of resignation, to believe that everything will work out just fine and we need not apply ourselves. I mean hope bolstered by critical thinking that is clear-headed in identifying what is lacking, in ourselves or the world, but then envisions ways to create it and endeavors to do that.

In its passivity and resignation, cynicism is a hardening, a calcification of the soul. Hope is a stretching of its ligaments, a limber reach for something greater.

Exercise and intermittent fasting improve brain plasticity and health

I have had numerous requests for a PDF of the article referenced in a Dec. 29, 2014 post - on how exercise and fasting stimulate brain plasticity and resilience - with the same title as this post.  It turns out that the reference pointed to by the link is open source. Readers should be able to download the article for themselves. Here is the text of the original post:

I thought it might be useful to point to this brief review by Praag et al. that references several recent pieces of work presented at a recent Soc. for Neuroscience Meeting symposium. The experiments indicate that exercise and intermittent energy restriction/fasting may optimize brain function and forestall metabolic and neurodegenerative diseases by enhancing neurogenesis, synaptic plasticity and neuronal stress robustness.  (Motivated readers can obtain the article from me.) Here is their central summary figure:

Exercise and IER/fasting exert complex integrated adaptive responses in the brain and peripheral tissues involved in energy metabolism. As described in the text, both exercise and IER enhance neuroplasticity and resistance of the brain to injury and disease. Some of the effects of exercise and IER on peripheral organs are mediated by the brain, including increased parasympathetic regulation of heart rate and increased insulin sensitivity of liver and muscle cells. In turn, peripheral tissues may respond to exercise and IER by producing factors that bolster neuronal bioenergetics and brain function. Examples include the following: mobilization of fatty acids in adipose cells and production of ketone bodies in the liver; production of muscle-derived neuroactive factors, such as irisin; and production of as yet unidentified neuroprotective “preconditioning factors.” Suppression of local inflammation in tissues throughout the body and the nervous system likely contributes to prevention and reversal of many different chronic disease processes.

Are electric vehicles really better for the planet?

Some time ago I read a careful analysis of the energy required to manufacture a Toyota Prius, which reported that more energy was expended over the life cycle of the typical vehicle (manufacturing the batteries being very energy intensive) than by a high efficiency gasoline-burning cars. I then lost the reference, and so was pleased to come upon the report below in Science Magazine by Wigginton. Work like this makes me feel a bit less guilty about staying with my cheap Honda Civic, and more able to resist the subtle aura of superiority that I imagine is being emitted by friends smugly driving about in their Toyota Priuses:

Shifting to electric passenger vehicles ideally will reduce the carbon footprint of the transportation sector. Two recent studies, however, show that the greenhouse gas emissions produced over the life cycle of electric vehicles, from production through use, may not always be less than those of gasoline-burning vehicles. Ellingsen et al. reveal that vehicle and battery size prohibit some larger electric vehicles from ever overcoming the high greenhouse gas emissions generated during production. Yuksel et al. show that regional factors in the United States such as electrical grid mix, temperature, and driving conditions strongly limit the potential of plug-in electric vehicles to out-perform high-efficiency gas vehicles. Blanket policies directed at the adoption of electric vehicles therefore could potentially fail to reduce the transportation sector's large carbon footprint.

Culture shapes the evolution of cognition.

From Thompson et al.:

A central debate in cognitive science concerns the nativist hypothesis, the proposal that universal features of behavior reflect a biologically determined cognitive substrate: For example, linguistic nativism proposes a domain-specific faculty of language that strongly constrains which languages can be learned. An evolutionary stance appears to provide support for linguistic nativism, because coordinated constraints on variation may facilitate communication and therefore be adaptive. However, language, like many other human behaviors, is underpinned by social learning and cultural transmission alongside biological evolution. We set out two models of these interactions, which show how culture can facilitate rapid biological adaptation yet rule out strong nativization. The amplifying effects of culture can allow weak cognitive biases to have significant population-level consequences, radically increasing the evolvability of weak, defeasible inductive biases; however, the emergence of a strong cultural universal does not imply, nor lead to, nor require, strong innate constraints. From this we must conclude, on evolutionary grounds, that the strong nativist hypothesis for language is false. More generally, because such reciprocal interactions between cultural and biological evolution are not limited to language, nativist explanations for many behaviors should be reconsidered: Evolutionary reasoning shows how we can have cognitively driven behavioral universals and yet extreme plasticity at the level of the individual—if, and only if, we account for the human capacity to transmit knowledge culturally. Wherever culture is involved, weak cognitive biases rather than strong innate constraints should be the default assumption.

A model for aggression and violence around the world.

I want to pass on the abstract of a forthcoming article in Brain and Behavioral Science for which reviewer's comments are being solicited. (I'm on the mailing list of potential reviewers because I authored an article in the journal in the 1990s). It's model of climate, aggression, and self control makes total sense in terms of my experience of living both in Madison Wisconsin (from May-September) and Fort Lauderdale Florida (October-April). (I returned to Madison two weeks ago and, as usual, have been struck by how much less defensiveness and aggression is exhibited by strangers in public in the more northern Madison location. Strangers at grocery stores are more benign, pleasant, and occasionally even make eye contact!)

Target Article: Aggression and Violence Around the World: A Model of Climate, Aggression, and Self-control in Humans (CLASH)

Authors: Paul A. M. Van Lange, Maria I. Rinderu, and Brad J. Bushman

Deadline for Commentary Proposals: Thursday June 9, 2016

Abstract: Worldwide there are substantial differences within and between countries in aggression and violence. Although there are various exceptions, a general rule is that aggression and violence increase as one moves closer to the equator, which suggests the important role of climate differences. While this pattern is robust, theoretical explanations for these large differences in aggression and violence within countries and around the world are lacking. Most extant explanations focus on the influence of average temperature as a factor that triggers aggression (The General Aggression Model), or the notion that warm temperature allows for more social interaction situations (Routine Activity Theory) in which aggression is likely to unfold. We propose a new model of CLimate, Aggression, and Self-control in Humans (CLASH) that seeks to understand differences within and between countries in aggression and violence in terms of differences in climate. Lower temperatures, and especially larger degrees of seasonal variation in climate, calls for individuals and groups to adopt a slower life history strategy, and exert more focus on the future (versus present), and a stronger focus on self-control. The CLASH model further outlines that slow life strategy, future orientation, and strong self-control are important determinants of inhibiting aggression and violence. We also discuss how CLASH is different from other recently developed models that emphasize climate differences for understanding conflict. We conclude by discussing the theoretical and societal importance of climate in shaping individual and societal differences in aggression and violence.

The Dalai Lama’s Atlas of emotions

You might have a look at this curious website pointed to by Kevin Randall, an atlas of emotions developed by Paul Ekman and collaborators commissioned by the Dalai Lama (who paid ~$750,000 for the project). After surveying 248 of the most active emotion researchers in the world, Ekman chose to divide emotions into five broad categories (anger, fear, disgust, sadness and enjoyment), each having an elaborate subset of emotional states, triggers, actions and moods. A cartography and data visualization firm was engaged to help depict them in a visual, and hopefully useful, way.

I'm really at a bit of a loss to figure out how the byzantine complexity of the beautiful graphic displays are supposed to be useful. They don't quite do it for me. Maybe this is supposed to be a lookup guide for an emotion one is feeling but not quite categorizing? Sort of a bestiary of emotions? A well-intentioned effort, surely, but many of the descriptions seem quite banal and obvious.

When philosophy lost its way.

Frodeman and Briggle offer a lament over the irreversible passing of the practice of philosophy as a moral endeavor, one that might offer a view of the good society apart from the prescriptions of religion. Some clips from their essay:

Before its migration to the university, philosophy had never had a central home. Philosophers could be found anywhere — serving as diplomats, living off pensions, grinding lenses, as well as within a university. Afterward, if they were “serious” thinkers, the expectation was that philosophers would inhabit the research university…This purification occurred in response to at least two events. The first was the development of the natural sciences, as a field of study clearly distinct from philosophy, circa 1870, and the appearance of the social sciences in the decade thereafter. ..The second event was the placing of philosophy as one more discipline alongside these sciences within the modern research university. A result was that philosophy, previously the queen of the disciplines, was displaced, as the natural and social sciences divided the world between them.

Philosophers needed to embrace the structure of the modern research university, which consists of various specialties demarcated from one another. That was the only way to secure the survival of their newly demarcated, newly purified discipline. “Real” or “serious” philosophers had to be identified, trained and credentialed. Disciplinary philosophy became the reigning standard for what would count as proper philosophy.

Having adopted the same structural form as the sciences, it’s no wonder philosophy fell prey to physics envy and feelings of inadequacy. Philosophy adopted the scientific modus operandi of knowledge production, but failed to match the sciences in terms of making progress in describing the world. Much has been made of this inability of philosophy to match the cognitive success of the sciences. But what has passed unnoticed is philosophy’s all-too-successful aping of the institutional form of the sciences. We, too, produce research articles. We, too, are judged by the same coin of the realm: peer-reviewed products. We, too, develop sub-specializations far from the comprehension of the person on the street. In all of these ways we are so very “scientific.”

The act of purification accompanying the creation of the modern research university was not just about differentiating realms of knowledge. It was also about divorcing knowledge from virtue. Though it seems foreign to us now, before purification the philosopher (and natural philosopher) was assumed to be morally superior to other sorts of people. ..The study of philosophy elevated those who pursued it. Knowing and being good were intimately linked. It was widely understood that the point of philosophy was to become good rather than simply to collect or produce knowledge…The purification made it no longer sensible to speak of nature, including human nature, in terms of purposes and functions…By the late 19th century, Kierkegaard and Nietzsche had proved the failure of philosophy to establish any shared standard for choosing one way of life over another…There was a brief window when philosophy could have replaced religion as the glue of society; but the moment passed. People stopped listening as philosophers focused on debates among themselves.

Once knowledge and goodness were divorced, scientists could be regarded as experts, but there are no morals or lessons to be drawn from their work. Science derives its authority from impersonal structures and methods, not the superior character of the scientist. The individual scientist is no different from the average Joe, with no special authority to pronounce on what ought to be done…philosophy has aped the sciences by fostering a culture that might be called “the genius contest.” Philosophic activity devolved into a contest to prove just how clever one can be in creating or destroying arguments. Today, a hyperactive productivist churn of scholarship keeps philosophers chained to their computers. Like the sciences, philosophy has largely become a technical enterprise, the only difference being that we manipulate words rather than genes or chemicals. Lost is the once common-sense notion that philosophers are seeking the good life — that we ought to be (in spite of our failings) model citizens and human beings. Having become specialists, we have lost sight of the whole. The point of philosophy now is to be smart, not good. It has been the heart of our undoing.

This is how fascism comes to America

I pass on a few clips from a must-read article in the Washington Post by Robert Kagan, on Donald Trump:

Republican politicians marvel at how he has “tapped into” a hitherto unknown swath of the voting public. But what he has tapped into is what the founders most feared when they established the democratic republic: the popular passions unleashed, the “mobocracy.” Conservatives have been warning for decades about government suffocating liberty. But here is the other threat to liberty that Alexis de Tocqueville and the ancient philosophers warned about: that the people in a democracy, excited, angry and unconstrained, might run roughshod over even the institutions created to preserve their freedoms. As Alexander Hamilton watched the French Revolution unfold, he feared in America what he saw play out in France — that the unleashing of popular passions would lead not to greater democracy but to the arrival of a tyrant, riding to power on the shoulders of the people.

This phenomenon has arisen in other democratic and quasi-democratic countries over the past century, and it has generally been called “fascism.” Fascist movements, too, had no coherent ideology, no clear set of prescriptions for what ailed society. “National socialism” was a bundle of contradictions, united chiefly by what, and who, it opposed; fascism in Italy was anti-liberal, anti-democratic, anti-Marxist, anti-capitalist and anti-clerical. Successful fascism was not about policies but about the strongman, the leader (Il Duce, Der Fuhrer), in whom could be entrusted the fate of the nation. Whatever the problem, he could fix it. Whatever the threat, internal or external, he could vanquish it, and it was unnecessary for him to explain how. Today, there is Putinism, which also has nothing to do with belief or policy but is about the tough man who singlehandedly defends his people against all threats, foreign and domestic.

To understand how such movements take over a democracy, one only has to watch the Republican Party today. These movements play on all the fears, vanities, ambitions and insecurities that make up the human psyche. In democracies, at least for politicians, the only thing that matters is what the voters say they want — vox populi vox dei. A mass political movement is thus a powerful and, to those who would oppose it, frightening weapon. When controlled and directed by a single leader, it can be aimed at whomever the leader chooses. If someone criticizes or opposes the leader, it doesn’t matter how popular or admired that person has been. He might be a famous war hero, but if the leader derides and ridicules his heroism, the followers laugh and jeer. He might be the highest-ranking elected guardian of the party’s most cherished principles. But if he hesitates to support the leader, he faces political death.

This is how fascism comes to America, not with jackboots and salutes (although there have been salutes, and a whiff of violence) but with a television huckster, a phony billionaire, a textbook egomaniac “tapping into” popular resentments and insecurities, and with an entire national political party — out of ambition or blind party loyalty, or simply out of fear — falling into line behind him.

Brain modules that process human consensus decision-making

Suzuki et al. offer a study noting brain areas important in consensus decision-making, with different decision variables being associated with activity in different brain area that are integrated by distributed neural activity (See Network hubs in the human brain for an overall review of domains of cognitive function with some great summary graphics). The summary and abstract:

Highlights

•A task is used to study how the brain implements consensus decision-making 

•Consensus decision-making depends on three distinct computational processes 

•These different signals are encoded in distinct brain regions 

•Integration of these signals occurs in the dorsal anterior cingulate cortex

Summary

Consensus building in a group is a hallmark of animal societies, yet little is known about its underlying computational and neural mechanisms. Here, we applied a computational framework to behavioral and fMRI data from human participants performing a consensus decision-making task with up to five other participants. We found that participants reached consensus decisions through integrating their own preferences with information about the majority group members’ prior choices, as well as inferences about how much each option was stuck to by the other people. These distinct decision variables were separately encoded in distinct brain areas—the ventromedial prefrontal cortex, posterior superior temporal sulcus/temporoparietal junction, and intraparietal sulcus—and were integrated in the dorsal anterior cingulate cortex. Our findings provide support for a theoretical account in which collective decisions are made through integrating multiple types of inference about oneself, others, and environments, processed in distinct brain modules.

Aerobic fitness: one minute of all out effort = 45 min. of moderate effort

Reynolds has written a series of articles describing experiments showing the benefits of high-intensity interval training. She now points to a study by Gillen et al. showing that high intensity effort periods of only 1 minute can have a big effect. Twelve weeks of a regime of 3 cycling sessions per week lasting 10 minutes each, with only one minute of that time being strenuous, caused the same 20% increase in aerobic fitness as sessions of 45 min of cycling at a moderate pace.

America in decline?

I pass on a few clips from Easterbrook's article, on the prevailing negative depiction (especially by Republican candidates) of America's current state and direction:

...most American social indicators have been positive at least for years, in many cases for decades. The country is, on the whole, in the best shape it’s ever been in. So what explains all the bad vibes?..the core reason for the disconnect between the nation’s pretty-good condition and the gloomy conventional wisdom is that optimism itself has stopped being respectable. Pessimism is now the mainstream, with optimists viewed as Pollyannas. If you don’t think everything is awful, you don’t understand the situation!

Objectively, the glass looks significantly more than half full.

Job growth has been strong for five years, with unemployment now below where it was for most of the 1990s, a period some extol as the “good old days.” The American economy is No. 1 by a huge margin, larger than Nos. 2 and 3 (China and Japan) combined. Americans are seven times as productive, per capita, as Chinese citizens. The dollar is the currency the world craves — which means other countries perceive America’s long-term prospects as very good.

Pollution, discrimination, crime and most diseases are in an extended decline; living standards, longevity and education levels continue to rise. The American military is not only the world’s strongest, it is the strongest ever. The United States leads the world in science and engineering, in business innovation, in every aspect of creativity, including the arts. Terrorism is a serious concern, but in the last 15 years, even taking into account Sept. 11, an American is five times more likely to be hit by lightning than to be killed by a terrorist.

Easterbrook continues with a discussion of the dire straits of the middle class, changes in manufacturing jobs ("Manufacturing jobs described by Mr. Trump and Mr. Sanders as “lost” to China cannot be found there, or anywhere."), etc.

...developing the postindustrial economy — while addressing issues such as inequality, greenhouse emissions and the condition of public schools — will require optimism. Pessimists think in terms of rear-guard actions to turn back the clock. Optimists understand that where the nation has faults, it’s time to roll up our sleeves and get to work.

That’s why the lack of progressive optimism is so keenly felt. In recent decades, progressives drank too deeply of instant-doomsday claims. If their predictions had come true, today petroleum would be exhausted, huge numbers of major animal species would be extinct, crop failures would be causing mass starvation, developing-world poverty would be getting worse instead of declining fast. (In 1990, 37 percent of humanity lived in what the World Bank defines as extreme poverty; today it’s 10 percent.)

Downsides of diversity.

I want to thank the anonymous commentator on the “Diversity makes you brighter” post, who sent links to interesting articles by Jonas and by Dinesena and Sønderskov. I pass on just some clips from Jonas, noting work by Putnam and Page:

...a fascinating new portrait of diversity emerging from recent scholarship. Diversity, it shows, makes us uncomfortable -- but discomfort, it turns out, isn't always a bad thing. Unease with differences helps explain why teams of engineers from different cultures may be ideally suited to solve a vexing problem. Culture clashes can produce a dynamic give-and-take, generating a solution that may have eluded a group of people with more similar backgrounds and approaches. At the same time, though, Putnam's work adds to a growing body of research indicating that more diverse populations seem to extend themselves less on behalf of collective needs and goals.

In more diverse communities, he says, there were neither great bonds formed across group lines nor heightened ethnic tensions, but a general civic malaise. And in perhaps the most surprising result of all, levels of trust were not only lower between groups in more diverse settings, but even among members of the same group...

So, there is a diversity paradox:

...those in more diverse communities may do more bowling alone, but the creative tensions unleashed by those differences in the workplace may vault those same places to the cutting edge of the economy and of creative culture.

Two ways to be satisfied.

Anna North points to an article by Helzer and Jayawickreme that examines two different control strategies for obtaining short and long term life satisfaction, “primary control” — the ability to directly affect one's circumstances — and “secondary control” — the ability to affect how one responds to those circumstances.

How does a sense of control relate to well-being? We consider two distinguishable control strategies, primary and secondary control, and their relationships with two facets of subjective well-being, daily positive/negative affective experience and global life satisfaction. Using undergraduate and online samples, the results suggest that these different control strategies are associated uniquely with distinct facets of well-being. After controlling for shared variance among constructs, primary control (the tendency to achieve mastery over circumstances via goal striving) was associated more consistently with daily affective experience than was secondary control, and secondary control (the tendency to achieve mastery over circumstances via sense-making) was associated more strongly with life satisfaction than primary control, but only within the student sample and community members not in a committed relationship. The results highlight the importance of both control strategies to everyday health and provide insights into the mechanisms underlying the relationship between control and well-being.

It is not clear why relationship status makes a difference. Helzer suggests that having a partner may help people deal with adversity the same way secondary control does, so secondary control may have less of an effect
