When intuition overrides reason.

Gilbert Chin points to work by Walco and Risen showing that a third to a half of us will elect to rely on gut feelings even after having demonstrated an accurate understanding of which choice is more likely to pay off. This suggests that error detection and correction are not coupled (as in Kahneman' dual process model, with system 1's intuitive default decision subject to system 2's determination of accuracy), but rather that detection and correction are not coupled. The abstract:

Will people follow their intuition even when they explicitly recognize that it is irrational to do so? Dual-process models of judgment and decision making are often based on the assumption that the correction of errors necessarily follows the detection of errors. But this assumption does not always hold. People can explicitly recognize that their intuitive judgment is wrong but nevertheless maintain it, a phenomenon known as acquiescence. Although anecdotes and experimental studies suggest that acquiescence occurs, the empirical case for acquiescence has not been definitively established. In four studies—using the ratio-bias paradigm, a lottery exchange game, blackjack, and a football coaching decision—we tested acquiescence using recently established criteria. We provide clear empirical support for acquiescence: People can have a faulty intuitive belief about the world (Criterion 1), acknowledge the belief is irrational (Criterion 2), but follow their intuition nonetheless (Criterion 3)—even at a cost.

On gratitude...

I want to pass on this bit from an essay by Philip Garrity in the New York Times Philosophy Forum "The Stone". On recovering from the vibrancy and trauma of illness he notes:

I notice myself falling back into that same pattern of trying to harness the vibrancy of illness...I am learning, however slowly, that maintaining that level of mental stamina, that fever pitch of experience, is less a recipe for enlightenment, and more for exhaustion.

The existentialist philosopher Jean-Paul Sartre describes our experience as a perpetual transitioning between unreflective consciousness, “living-in-the-world,” and reflective consciousness, “thinking-about-the-world.” Gratitude seems to necessitate an act of reflection on experience, which, in turn, requires a certain abstraction away from that direct experience. Paradoxically, our capacity for gratitude is simultaneously enhanced and frustrated as we strive to attain it.

Perhaps, then, there is an important difference between reflecting on wellness and experiencing wellness. My habitual understanding of gratitude had me forcefully lodging myself into the realm of reflective consciousness, pulling me away from living-in-the-world. I was constantly making an inventory of my wellness, too busy counting the coins to ever spend them.

Gratitude, in the experiential sense, requires that we wade back into the current of unreflective consciousness, which, to the egocentric mind, can easily feel like an annihilation of consciousness altogether. Yet, Sartre says that action that is unreflective isn’t necessarily unconscious. There is something Zen about this, the actor disappearing into the action. It is the way of the artist in the act of creative expression, the musician in the flow of performance. But, to most of us, it is a loss of self — and the sense of competency that comes with it.

If there is any sage in me, he says I must accept the vulnerability of letting the pain fade, of allowing the wounds to heal. Even in the wake of grave illness — or, more unsettlingly, in anticipation of it — we must risk falling back asleep into wellness.

Mind the Hype - Mindfulness and Meditation

Smith et al. point to and summarize an article by Van Dam et al. I pass on the Van Dam et al. abstract:

During the past two decades, mindfulness meditation has gone from being a fringe topic of scientific investigation to being an occasional replacement for psychotherapy, tool of corporate well-being, widely implemented educational practice, and “key to building more resilient soldiers.” Yet the mindfulness movement and empirical evidence supporting it have not gone without criticism. Misinformation and poor methodology associated with past studies of mindfulness may lead public consumers to be harmed, misled, and disappointed. Addressing such concerns, the present article discusses the difficulties of defining mindfulness, delineates the proper scope of research into mindfulness practices, and explicates crucial methodological issues for interpreting results from investigations of mindfulness. For doing so, the authors draw on their diverse areas of expertise to review the present state of mindfulness research, comprehensively summarizing what we do and do not know, while providing a prescriptive agenda for contemplative science, with a particular focus on assessment, mindfulness training, possible adverse effects, and intersection with brain imaging. Our goals are to inform interested scientists, the news media, and the public, to minimize harm, curb poor research practices, and staunch the flow of misinformation about the benefits, costs, and future prospects of mindfulness meditation.

And also Smith et al.'s list of points that seem fairly settled (they provide supporting references):

-Meditation almost certainly does sharpen your attention. 

-Long-term, consistent meditation does seem to increase resiliency to stress. 

-Meditation does appear to increase compassion. It also makes our compassion more effective. 

-Meditation does seem to improve mental health—but it’s not necessarily more effective than other steps you can take. 

-Mindfulness could have a positive impact on your relationships. 

-Mindfulness seems to reduce many kinds of bias. 

-Meditation does have an impact on physical health—but it’s modest.  

-Meditation might not be good for everyone all the time. 

-What kind of meditation is right for you? That depends. 

-How much meditation is enough? That also depends.

The 11 separate nations of the United States

I just became aware, through an article by Matthew Speiser in The Independent, of the interesting work of Oolin Woodard that suggests that 11 distinct cultures have historically divided the US. Speiser does capsule descriptions of the nations, given the names Yankedom, New Netherland, The Midlands, Tidewater, Greater Appalachia, Deep South, El Norte, The left Coast, The Far West, New France, and First Nation. They are illustrated by the following graphic from his article:

Autopilots and metastates of our brains.

I pass on summaries from two recent contributions to understanding automatic information processing in our brains. First from Vatansever et al., work showing a role of the default mode network that has been a subject of many MindBlog posts:

Concurrent with mental processes that require rigorous computation and control, a series of automated decisions and actions govern our daily lives, providing efficient and adaptive responses to environmental demands. Using a cognitive flexibility task, we show that a set of brain regions collectively known as the default mode network plays a crucial role in such “autopilot” behavior, i.e., when rapidly selecting appropriate responses under predictable behavioral contexts. While applying learned rules, the default mode network shows both greater activity and connectivity. Furthermore, functional interactions between this network and hippocampal and parahippocampal areas as well as primary visual cortex correlate with the speed of accurate responses. These findings indicate a memory-based “autopilot role” for the default mode network, which may have important implications for our current understanding of healthy and adaptive brain processing.

Also, Vidaurre et al. describe two distinct networks, or metastates, within which the brain cycles.

We address the important question of the temporal organization of large-scale brain networks, finding that the spontaneous transitions between networks of interacting brain areas are predictable. More specifically, the network activity is highly organized into a hierarchy of two distinct metastates, such that transitions are more probable within, than between, metastates. One of these metastates represents higher order cognition, and the other represents the sensorimotor systems. Furthermore, the time spent in each metastate is subject-specific, is heritable, and relates to behavior. Although evidence of non–random-state transitions has been found at the microscale, this finding at the whole-brain level, together with its relation to behavior, has wide implications regarding the cognitive role of large-scale resting-state networks.

Detailed demographics from Google Street Views.

Interesting....neighborhood-level estimates of the racial, economic and political characteristics of 200 U.S. cities using Google Street View images of people's cars. ...From Gebru et al.:

The United States spends more than $250 million each year on the American Community Survey (ACS), a labor-intensive door-to-door study that measures statistics relating to race, gender, education, occupation, unemployment, and other demographic factors. Although a comprehensive source of data, the lag between demographic changes and their appearance in the ACS can exceed several years. As digital imagery becomes ubiquitous and machine vision techniques improve, automated data analysis may become an increasingly practical supplement to the ACS. Here, we present a method that estimates socioeconomic characteristics of regions spanning 200 US cities by using 50 million images of street scenes gathered with Google Street View cars. Using deep learning-based computer vision techniques, we determined the make, model, and year of all motor vehicles encountered in particular neighborhoods. Data from this census of motor vehicles, which enumerated 22 million automobiles in total (8% of all automobiles in the United States), were used to accurately estimate income, race, education, and voting patterns at the zip code and precinct level. (The average US precinct contains ∼1,000 people.) The resulting associations are surprisingly simple and powerful. For instance, if the number of sedans encountered during a drive through a city is higher than the number of pickup trucks, the city is likely to vote for a Democrat during the next presidential election (88% chance); otherwise, it is likely to vote Republican (82%). Our results suggest that automated systems for monitoring demographics may effectively complement labor-intensive approaches, with the potential to measure demographics with fine spatial resolution, in close to real time.

From the summary by Ingraham:

...The 22 million vehicles in the Google Street View database comprise roughly 8 percent of all vehicles in the United States...the researchers first paired the Zip code-level vehicle data with numbers on race, income and education from the U.S. Census Bureau'sAmerican Community Survey. They did this for a random 15 percent of the Zip codes in their data set to create a “training set.” They then created another algorithm to go through the training set to see how vehicle characteristics correlated with neighborhood characteristics: What kinds of vehicles are disproportionately likely to appear in white neighborhoods, or black ones? Low-income vs. high-income? Highly-educated areas vs. less-educated ones?

You can do similar exercises for other demographic characteristics, like educational attainment. People with graduate degrees were more likely to drive Audi hatchbacks with high city MPG. Those with less than a high school education, on the other hand, were more likely to drive cars made by U.S. manufacturers in the 1990s.

“We found a strong correlation between our results and ACS [American Community Survey] values for every demographic statistic we examined,” the researchers wrote. They plotted the algorithm's demographic estimates against the actual numbers from the ACS and measured their correlation coefficient: a number from zero (no correlation) to 1 (perfect correlation) that measures how accurately one set of numbers can predict the variation in a separate set of numbers.

At the city level, the algorithm did a particularly good job of predicting the percent of Asians (correlation coefficient of 0.87), blacks (0.82) and whites (0.77). It also predicted median household income (0.82) quite well. On measures of educational attainment, the correlation coefficients ran from about 0.54 to 0.70 — again, not perfect, but fairly impressive accuracy considering the predictions derived solely from auto information and nothing else.

Some morning Rachmaninoff - Fantasy Piece, in E, Op. 3. No. 3

Here is a Rachmaninoff Fantasy Piece, in E, Op. 3 No. 3, which I recorded last week, continuing to play with using my new iPhone X with a USB Zoom iQ6 condenser microphone in the lightning port for making video recordings that can be edited and then sent directly to YouTube.

Wealth inequality as a law of nature.

Here is the abstract from Scheffer et al.,  a bit of work that casts an interesting light on the current Republican tax legislation that significantly accelerates the unequal distribution of wealth in this country, as described nicely by David Leonhardt:

Significance

Inequality is one of the main drivers of social tension. We show striking similarities between patterns of inequality between species abundances in nature and wealth in society. We demonstrate that in the absence of equalizing forces, such large inequality will arise from chance alone. While natural enemies have an equalizing effect in nature, inequality in societies can be suppressed by wealth-equalizing institutions. However, over the past millennium, such institutions have been weakened during periods of societal upscaling. Our analysis suggests that due to the very same mathematical principle that rules natural communities (indeed, a “law of nature”) extreme wealth inequality is inevitable in a globalizing world unless effective wealth-equalizing institutions are installed on a global scale.

Abstract

Most societies are economically dominated by a small elite, and similarly, natural communities are typically dominated by a small fraction of the species. Here we reveal a strong similarity between patterns of inequality in nature and society, hinting at fundamental unifying mechanisms. We show that chance alone will drive 1% or less of the community to dominate 50% of all resources in situations where gains and losses are multiplicative, as in returns on assets or growth rates of populations. Key mechanisms that counteract such hyperdominance include natural enemies in nature and wealth-equalizing institutions in society. However, historical research of European developments over the past millennium suggests that such institutions become ineffective in times of societal upscaling. A corollary is that in a globalizing world, wealth will inevitably be appropriated by a very small fraction of the population unless effective wealth-equalizing institutions emerge at the global level.

Figure - Inequality in society (Left) and nature (Right). The Upper panels illustrate the similarity between the wealth distribution of the world’s 1,800 billionaires (A) (8) and the abundance distribution among the most common trees in the Amazon forest (B) (3). The Lower panels illustrate inequality in nature and society more systematically, comparing the Gini index of wealth in countries (C) and the Gini index of abundance in a large set of natural communities (D). (The Gini index is an indicator of inequality that ranges from 0 for entirely equal distributions to 1 for the most unequal situation. It is a more integrative indicator of inequality than the fraction that represents 50%, but the two are closely related in practice. Surprisingly, Gini indices for our natural communities are quite similar to the Gini indices for wealth distributions of 181 countries.)

Skill networks and human capital.

Anderson does an interesting analysis showing that workers who can combine different skills synergistically earn more than other skilled workers. I pass on both the Abstract and the Significance statements:

Significance

The relationship between worker human capital and wages is a question of considerable economic interest. Skills are usually characterized using a one-dimensional measure, such as years of training. However, in knowledge-based production, the interaction between a worker’s skills is also important. Here, we propose a network-based method for characterizing worker skill sets. We construct a human capital network, wherein nodes are skills and two skills are connected if a worker has both or both are required for the same job. We then illustrate the method by analyzing an online freelance labor market, showing that workers with diverse skills earn higher wages and that those who use their diverse skills in combination earn the highest wages of all.

Abstract

We propose a network-based method for measuring worker skills. We illustrate the method using data from an online freelance website. Using the tools of network analysis, we divide skills into endogenous categories based on their relationship with other skills in the market. Workers who specialize in these different areas earn dramatically different wages. We then show that, in this market, network-based measures of human capital provide additional insight into wages beyond traditional measures. In particular, we show that workers with diverse skills earn higher wages than those with more specialized skills. Moreover, we can distinguish between two different types of workers benefiting from skill diversity: jacks-of-all-trades, whose skills can be applied independently on a wide range of jobs, and synergistic workers, whose skills are useful in combination and fill a hole in the labor market. On average, workers whose skills are synergistic earn more than jacks-of-all-trades.

Positive stimuli blur time.

From Roberts et al.:

Anecdotal reports that time “flies by” or “slows down” during emotional events are supported by evidence that the motivational relevance of stimuli influences subsequent duration judgments. Yet it is unknown whether the subjective quality of events as they unfold is altered by motivational relevance. In a novel paradigm, we measured the subjective experience of moment-to-moment visual perception. Participants judged the temporal smoothness of high-approach positive images (desserts), negative images (e.g., of bodily mutilation), and neutral images (commonplace scenes) as they faded to black. Results revealed approach-motivated blurring, such that positive stimuli were judged as smoother and negative stimuli as choppier relative to neutral stimuli. Participants’ ratings of approach motivation predicted perceived fade smoothness after we controlled for low-level stimulus features. Electrophysiological data indicated that approach-motivated blurring modulated relatively rapid perceptual activation. These results indicate that stimulus value influences subjective temporal perceptual acuity; approach-motivating stimuli elicit perception of a “blurred” frame rate characteristic of speeded motion.

Teaching A.I. to explain itself

An awkward feature of the artificial intelligence, or machine learning, algorithms that teach themselves to translate languages, analyze X-ray images and mortgage loans, judge probability of behaviors from faces, etc., is that we are unable to discern exactly what they are doing as they perform these functions. How can we we trust these machine unless they can explain themselves? This issue is the subject of an interesting piece by Cliff Kuang. A few clips from the article:

Instead of certainty and cause, A.I. works off probability and correlation. And yet A.I. must nonetheless conform to the society we’ve built — one in which decisions require explanations, whether in a court of law, in the way a business is run or in the advice our doctors give us. The disconnect between how we make decisions and how machines make them, and the fact that machines are making more and more decisions for us, has birthed a new push for transparency and a field of research called explainable A.I., or X.A.I. Its goal is to make machines able to account for the things they learn, in ways that we can understand.

A decade in the making, the European Union’s General Data Protection Regulation finally goes into effect in May 2018. It’s a sprawling, many-tentacled piece of legislation whose opening lines declare that the protection of personal data is a universal human right. Among its hundreds of provisions, two seem aimed squarely at where machine learning has already been deployed and how it’s likely to evolve. Google and Facebook are most directly threatened by Article 21, which affords anyone the right to opt out of personally tailored ads. The next article then confronts machine learning head on, limning a so-called right to explanation: E.U. citizens can contest “legal or similarly significant” decisions made by algorithms and appeal for human intervention. Taken together, Articles 21 and 22 introduce the principle that people are owed agency and understanding when they’re faced by machine-made decisions.

To create a neural net that can reveal its inner workings...researchers...are pursuing a number of different paths. Some of these are technically ingenious — for example, designing new kinds of deep neural networks made up of smaller, more easily understood modules, which can fit together like Legos to accomplish complex tasks. Others involve psychological insight: One team at Rutgers is designing a deep neural network that, once it makes a decision, can then sift through its data set to find the example that best demonstrates why it made that decision. (The idea is partly inspired by psychological studies of real-life experts like firefighters, who don’t clock in for a shift thinking, These are the 12 rules for fighting fires; when they see a fire before them, they compare it with ones they’ve seen before and act accordingly.) Perhaps the most ambitious of the dozen different projects are those that seek to bolt new explanatory capabilities onto existing deep neural networks. Imagine giving your pet dog the power of speech, so that it might finally explain what’s so interesting about squirrels. Or, as Trevor Darrell, a lead investigator on one of those teams, sums it up, “The solution to explainable A.I. is more A.I.”

... a novel idea for letting an A.I. teach itself how to describe the contents of a picture...create two deep neural networks: one dedicated to image recognition and another to translating languages. ...they lashed these two together and fed them thousands of images that had captions attached to them. As the first network learned to recognize the objects in a picture, the second simply watched what was happening in the first, then learned to associate certain words with the activity it saw. Working together, the two networks could identify the features of each picture, then label them. Soon after, Darrell was presenting some different work to a group of computer scientists when someone in the audience raised a hand, complaining that the techniques he was describing would never be explainable. Darrell, without a second thought, said, Sure — but you could make it explainable by once again lashing two deep neural networks together, one to do the task and one to describe it.

Debussy La plus que lente - a first musical offering from Austin Texas.

This is a personal post, a musical offering of the sort I have done on MindBlog in previous years. The Steinway B that I have used since 2002 recently moved with me from Fort Lauderdale, Florida to Austin, Texas, not to the family house I moved back into, but to the larger living room of my son's home which can manage the kind of musical socials I have given for many years.  Techie MindBlog readers might be interested in my discovery that the video camera on my iPhone X is better than the Canon video camera I had been using, and that a small USB Zoom iQ6 condenser microphone attached to its Lightning connector gives audio quality comparable to the much larger C1 Studio condenser microphone whose output had to be tediously synchronized with video from the Canon camera stripped of its inferior audio sound track.

Digital mass persuasion via psychological targeting.

Sigh...we're heading full-tilt towards a plutocracy which will manipulate the masses via technologies of the sort described by Matz et al.:

Significance

Building on recent advancements in the assessment of psychological traits from digital footprints, this paper demonstrates the effectiveness of psychological mass persuasion—that is, the adaptation of persuasive appeals to the psychological characteristics of large groups of individuals with the goal of influencing their behavior. On the one hand, this form of psychological mass persuasion could be used to help people make better decisions and lead healthier and happier lives. On the other hand, it could be used to covertly exploit weaknesses in their character and persuade them to take action against their own best interest, highlighting the potential need for policy interventions.

Abstract

People are exposed to persuasive communication across many different contexts: Governments, companies, and political parties use persuasive appeals to encourage people to eat healthier, purchase a particular product, or vote for a specific candidate. Laboratory studies show that such persuasive appeals are more effective in influencing behavior when they are tailored to individuals’ unique psychological characteristics. However, the investigation of large-scale psychological persuasion in the real world has been hindered by the questionnaire-based nature of psychological assessment. Recent research, however, shows that people’s psychological characteristics can be accurately predicted from their digital footprints, such as their Facebook Likes or Tweets. Capitalizing on this form of psychological assessment from digital footprints, we test the effects of psychological persuasion on people’s actual behavior in an ecologically valid setting. In three field experiments that reached over 3.5 million individuals with psychologically tailored advertising, we find that matching the content of persuasive appeals to individuals’ psychological characteristics significantly altered their behavior as measured by clicks and purchases. Persuasive appeals that were matched to people’s extraversion or openness-to-experience level resulted in up to 40% more clicks and up to 50% more purchases than their mismatching or unpersonalized counterparts. Our findings suggest that the application of psychological targeting makes it possible to influence the behavior of large groups of people by tailoring persuasive appeals to the psychological needs of the target audiences. We discuss both the potential benefits of this method for helping individuals make better decisions and the potential pitfalls related to manipulation and privacy.

Trauma is passed over generations.

Bakalar points to work by Santavirta et al. showing that the daughters of women exposed to childhood trauma are at increased risk for psychiatric disorders. The study compared the health of female offspring of ~47,000 Finnish children who were evacuated to Swedish foster homes during World War II, with offspring of female cousins who had not been evacuated. The study:

...found that female children of mothers who had been evacuated to Sweden were twice as likely to be hospitalized for a psychiatric illness as their female cousins who had not been evacuated, and more than four times as likely to have depression or bipolar disorder...But there was no effect among male children, and no effect among children of either sex born to fathers who had been evacuated.

How is American (and World) governance evolving?

So... what is the United State to become? From the recent outpouring of Op-Ed pieces you can take your choice: Autocracy, Plutocracy, Oligarchy, Kleptocracy... with liberal democracy viewed as vitally threatened. Articles by Thomas Edsall and Andrew Sullivan describe how American democracy is destroying itself, as Roger Cohen sadly notes the irreversible passing of the Pax Americana, an ordering of the world that began with Woodrow Wilson's 14 points speech one hundred years ago. David Frum outlines steps towards Autocracy as Jonathan Rauch discusses whether Trump will be able to govern as an authoritarian. Paul Krugman notes how the current tax reform will enormously enhance the ongoing process of entrenching a hereditary plutocracy that actually runs the country.  Articles by Fareed Zakaria and Thomas Edsall describe how the liberal establishment has failed to understand its own role in the rise of contemporary conservatism, how its social and economic policies have disadvantaged formerly middle class voters more motivated by issues surrounding religion, race, and culture than they are by economics, thus fueling a rise of nationalism, nativism and xenophobia in both the U.S. and Europe.  Regarding this last point, I want to paste in here the final paragraphs of an Edsall Op-Ed piece noting Eric Schnurer's argument that blue America has over the last decade declared war on the "red way of life."

The political, economic, and cultural triumph nationwide of a set of principles and realities essentially alien to large numbers of Americans is viewed as (a) being imposed upon them, and (b) overturning much of what they take for granted in their lives — and I don’t think they’re wrong about that. I think they’ve risen in angry revolt, and now intend to give back to the “elite” in the same terms that they’ve been given to. I don’t think this is good — in fact, I think it’s a very dangerous situation — but I think we need to understand it in order to responsibly address it.

Do liberals in fact need to understand — or empathize with — their many antagonists, the men and women who are sharply critical of the liberal project?

Steven Pinker, a professor of psychology at Harvard, observes that “believers in liberal democracy have unilaterally disarmed in the defense of the institution” by agreeing in many cases with the premise of the Trump campaign: “that the country is a hopeless swamp.” This left Democrats “defenseless when he proposed to drain it.” Where, Pinker asks,

are the liberals who are willing to say that liberal democracy has worked? That environmental regulations have slashed air pollutants while allowing Americans to drive more miles and burn more fuel? That social transfers have reduced poverty rates fivefold? That globalization has allowed Americans to afford more food, clothing, TVs, cars, and air-conditioners? That international organizations have prevented nuclear war, and reduced the rate of death in warfare by 90 percent? That environmental treaties are healing the hole in the ozone layer?

Pinker remains confident:

Progress always must fight headwinds. Human nature doesn’t change, and the appeal of regressive impulses is perennial. The forces of liberalism, modernity, cosmopolitanism, the open society, and Enlightenment values always have to push against our innate tribalism, authoritarianism, and thirst for vengeance. We can even recognize these instincts in ourselves, even in Trump’s cavalier remarks about the rule of law...Over the longer run, I think the forces of modernity prevail — affluence, education, mobility, communication, and generational replacement. Trumpism, like Brexit and European populism, are old men’s movements: support drops off sharply with age.

Pinker is optimistic about the future. I hope he is right.

The problem is that even if Pinker is right, his analysis does not preclude a sustained period in which the anti-democratic right dominates American politics. There is no telling how long it will be before the movement Trump has mobilized will have run its course. Nor can we anticipate — if and when Trumpism does implode — how extensive the damage will be that Pinker’s “forces of modernity” will have to repair.

But... what if all of this wringing of hands about changes the political order is a thin veneer over deeper changes that are really going to end up controlling the show?  One is seeing now the rise of a de facto world government of interlocked and interdependent giant corporations, mainly in the U.S. and China (think Apple and Foxconn) versed in the neuroeconomic techniques central to influencing the behaviors, desires, and consumptions of their subjects.  They are assembling a level of power that might increasingly override the ability of individual nation states to contest or control their actions.  Will this ensemble nudge towards mirroring the values of liberalism currently reflected in the public stances of the largest U.S. corporations, or will the political accommodations shown by  their Asian counterparts be more likely to prevail?

Dogs can smell our happiness and fear.

From D'Aniello et al:

We report a study examining interspecies emotion transfer via body odors (chemosignals). Do human body odors (chemosignals) produced under emotional conditions of happiness and fear provide information that is detectable by pet dogs (Labrador and Golden retrievers)? The odor samples were collected from the axilla of male donors not involved in the main experiment. The experimental setup involved the co-presence of the dog's owner, a stranger and the odor dispenser in a space where the dogs could move freely. There were three odor conditions [fear, happiness, and control (no sweat)] to which the dogs were assigned randomly. The dependent variables were the relevant behaviors of the dogs (e.g., approaching, interacting and gazing) directed to the three targets (owner, stranger, sweat dispenser) aside from the dogs' stress and heart rate indicators. The results indicated with high accuracy that the dogs manifested the predicted behaviors in the three conditions. There were fewer and shorter owner directed behaviors and more stranger directed behaviors when they were in the "happy odor condition" compared to the fear odor and control conditions. In the fear odor condition, they displayed more stressful behaviors. The heart rate data in the control and happy conditions were significantly lower than in the fear condition. Our findings suggest that interspecies emotional communication is facilitated by chemosignals.

How Evil is Tech?

The title of this post is from an Op-Ed piece by David Brooks. Some clips:

There are three main critiques of big tech.

The first is that it is destroying the young. Social media promises an end to loneliness but actually produces an increase in solitude and an intense awareness of social exclusion. Texting and other technologies give you more control over your social interactions but also lead to thinner interactions and less real engagement with the world.

The second critique of the tech industry is that it is causing this addiction on purpose, to make money. Tech companies understand what causes dopamine surges in the brain and they lace their products with “hijacking techniques” that lure us in and create “compulsion loops.”

The third critique is that Apple, Amazon, Google and Facebook are near monopolies that use their market power to invade the private lives of their users and impose unfair conditions on content creators and smaller competitors. The political assault on this front is gaining steam.

The big breakthrough will come when tech executives clearly acknowledge the central truth: Their technologies are extremely useful for the tasks and pleasures that require shallower forms of consciousness, but they often crowd out and destroy the deeper forms of consciousness people need to thrive...Online is a place for human contact but not intimacy. Online is a place for information but not reflection.

Rabbi Abraham Joshua Heschel wrote that we take a break from the distractions of the world not as a rest to give us more strength to dive back in, but as the climax of living. “The seventh day is a palace in time which we build. It is made of soul, joy and reticence,” he said. By cutting off work and technology we enter a different state of consciousness, a different dimension of time and a different atmosphere, a “mine where the spirit’s precious metal can be found.”

Imagine if instead of claiming to offer us the best things in life, tech merely saw itself as providing efficiency devices. Its innovations can save us time on lower-level tasks so we can get offline and there experience the best things in life.

Imagine if tech pitched itself that way. That would be an amazing show of realism and, especially, humility, which these days is the ultimate and most disruptive technology.

Trust and cooperation across societies.

Romano et al. (open source) offer, in a study over 17 countries, an example of the kind of research needed to understand and enhance cooperation within and between groups.

Significance

In a study including 17 societies, we found that people are motivated to trust and cooperate more with their ingroup, than harm the outgroup. Reputation-based indirect reciprocity may offset this ingroup favoritism, because we found that reputational concern universally increases cooperation with both ingroup and outgroup members. We also found that people who are dispositionally cooperative are less parochial and more universal in their cooperation. In a time of increasing parochialism in both domestic and international relations, our findings affirm us of the danger of the strong human universal toward parochial altruism. Yet, our findings suggest that in all societies, there exist people whose cooperation transcends group boundaries and provides a solution to combating parochialism: reputation-based indirect reciprocity.

Abstract

International challenges such as climate change, poverty, and intergroup conflict require countries to cooperate to solve these complex problems. However, the political tide in many countries has shifted inward, with skepticism and reluctance to cooperate with other countries. Thus, cross-societal investigations are needed to test theory about trust and cooperation within and between groups. We conducted an experimental study in 17 countries designed to test several theories that explain why, who, and where people trust and cooperate more with ingroup members, compared with outgroup members. The experiment involved several interactions in the trust game, either as a trustor or trustee. We manipulated partner group membership in the trust game (ingroup, outgroup, or unknown) and if their reputation was at stake during the interaction. In addition to the standard finding that participants trust and cooperate more with ingroup than outgroup members, we obtained findings that reputational concerns play a decisive role for promoting trust and cooperation universally across societies. Furthermore, men discriminated more in favor of their ingroup than women. Individual differences in cooperative preferences, as measured by social value orientation, predicted cooperation with both ingroup and outgroup members. Finally, we did not find support for three theories about the cross-societal conditions that influence the degree of ingroup favoritism observed across societies (e.g., material security, religiosity, and pathogen stress). We discuss the implications for promoting cooperation within and between countries.

The emotional political base supporting the consolidation of the U.S. plutocracy.

I want to pass on the ending paragraphs from a piece by Fareed Zakaria:

Is it that the Republican Party is cleverly and successfully hoodwinking its supporters, promising them populism and enacting plutocratic capitalism instead? This view has been a staple of liberal analysis for years, most prominently in Thomas Frank’s book “What’s the Matter with Kansas?” Frank argued that Republicans have been able to work this magic trick by dangling social issues in front of working-class voters, who fall for the bait and lose sight of the fact that they are voting against their own interests. Both Wolf and Pierson believe that this trickery will prove dangerous for Republicans. “The plutocrats are riding on a hungry tiger,” writes Wolf.

But what if people are not being fooled at all? What if people are actually motivated far more deeply by issues surrounding religion, race and culture than they are by economics? There is increasing evidence that Trump’s base supports him because they feel a deep emotional, cultural and class affinity for him. And while the tax bill is analyzed by economists, Trump picks fights with black athletes, retweets misleading anti-Muslim videos and promises not to yield on immigration. Perhaps he knows his base better than we do. In fact, Trump’s populism might not be as unique as it’s made out to be. Polling from Europe suggests that the core issues motivating people to support Brexit or the far-right parties in France and Germany, and even the populist parties of Eastern Europe, are cultural and social.

The most important revolution in economics in the past generation has been the rise of the behavioral scientists, trained in psychology, who are finding that people systematically make decisions that are against their own “interests.” This might be the tip of the iceberg in understanding human motivation. The real story might be that people see their own interests in much more emotional and tribal ways than scholars understand. What if, in the eyes of a large group of Americans, these other issues are the ones for which they will stand up, protest, support politicians and even pay an economic price? What if, for many people, in America and around the world, these are their true interests?

A mind reading machine?

Not quite, but Matthew Hutson points to work by Wen et al. using an artificial neural network to categorize fMRI signals from subjects watching different categories of images. The algorithm could predict with about 50% accuracy which of 15 classes of visual object a subject was watching. His description:

Artificial intelligence has taken us one baby step closer to the mind-reading machines of science fiction. Researchers have developed “deep learning” algorithms—roughly modeled on the human brain—to decipher, you guessed it, the human brain. First, they built a model of how the brain encodes information. As three women spent hours viewing hundreds of short videos, a functional MRI machine measured signals of activity in the visual cortex and elsewhere. A popular type of artificial neural network used for image processing learned to associate video images with brain activity. As the women watched additional clips, the algorithm’s predicted activity correlated with actual activity in a dozen brain regions. It also helped the scientists visualize which features each area of the cortex was processing. Another network decoded neural signals: Based on a participant’s brain activity, it could predict with about 50% accuracy what she was watching (by selecting one of 15 categories including bird, airplane, and exercise). If the network had trained on data from a different woman’s brain, it could still categorize the image with about 25% accuracy, the researchers report this month in Cerebral Cortex. The network could also partially reconstruct what a participant saw, turning brain activity into pixels, but the resulting images were little more than white blobs. The researchers hope their work will lead to the reconstruction of mental imagery, which uses some of the same brain circuits as visual processing. Translating from the mind’s eye into bits could allow people to express vivid thoughts or dreams to computers or to other people without words or mouse clicks, and could help those with strokes who have no other way to communicate.
