We navigate with stereo smell

From Wu et al.:

Significance

The human brain exploits subtle differences between the inputs to the paired eyes and ears to construct three-dimensional experiences and navigate the environment. Whether and how it does so for olfaction is unclear, although humans also have two separate nasal passages that simultaneously sample from nonoverlapping regions in space. Here, we demonstrate that a moderate internostril difference in odor intensity consistently biases recipients’ perceived direction of self-motion toward the higher-concentration side, despite that they cannot report which nostril smells a stronger odor. The findings indicate that humans have a stereo sense of smell that subconsciously guides navigation.

Abstract

Human navigation relies on inputs to our paired eyes and ears. Although we also have two nasal passages, there has been little empirical indication that internostril differences yield directionality in human olfaction without involving the trigeminal system. By using optic flow that captures the pattern of apparent motion of surface elements in a visual scene, we demonstrate through formal psychophysical testing that a moderate binaral concentration disparity of a nontrigeminal odorant consistently biases recipients’ perceived direction of self-motion toward the higher-concentration side, despite that they cannot verbalize which nostril smells a stronger odor. We further show that the effect depends on the internostril ratio of odor concentrations and not the numeric difference in concentration between the two nostrils. Taken together, our findings provide behavioral evidence that humans smell in stereo and subconsciously utilize stereo olfactory cues in spatial navigation.

(By the way, a previous MindBlog post points to work showing binaral rivalry between the nostrils, analogous to the binocular rivalry that has been studied for over a century.)

The enlightenment returns.

 OhMyGawd..... I just came across the following MindBlog post from March 31, 2009, celebrating Obama's statement on restoring government guided by rationality and scientific integrity.  I pray that I can do do a similar post next March with Biden's name replacing Obama's.....

I have been almost reduced to tears of gratitude by Obama's statements on restoring an American government that is guided by rationality and scientific integrity rather than a conservative religious faith that distorts both. Kurt Gottfried and Harold Varmus (see below) write an editorial in Science Magazine that salutes this (Here is the President's memorandum):

The authors of the Declaration of Independence and the Constitution of the United States were children of the Enlightenment. They understood the power that flows from combining human reason with empirical knowledge, and they assumed that the political system they were creating would thrive only in a culture that upheld the values of the Enlightenment. And thrive it did, in large part because our people and government upheld those values throughout most of U.S. history. Recently, however, the precepts of the Enlightenment were ignored and even disdained with respect to the manner in which science was used in the nation's governance. Dogma took precedence over evidence, and opinion over facts. Happily, as was made clear by two policy announcements by President Barack Obama on 9 March 2009, the break in the traditionally harmonious relationship between science and government is now ending

As the president put it, "promoting science isn't just about providing resources--it is also about protecting free and open inquiry … free from manipulation or coercion, and listening to what [scientists] tell us, even when it's inconvenient--especially when it's inconvenient." In using the words "manipulation" and "coercion," the president was not speaking purely in the abstract; he was alluding to recent breaches of a code to which government must adhere if science is to play its proper role in advising the government on such complex issues as public health, climate change, or environmental protection. When the government systematically disregards this code, it undermines the historic role of science as a bulwark of an enlightened democracy.

In the president's Memorandum on Scientific Integrity last week, addressed to the heads of all executive departments and agencies, he directed those officials to neither suppress nor alter scientific and technological findings solicited in the process of policy formulation. He also asked that scientific information developed or used by the government be made readily available to the public. To put these directives in place, the president requested the director of the Office of Science and Technology Policy to develop, within 120 days, recommendations "designed to guarantee scientific integrity throughout the executive branch" and to ensure "that scientific data is never distorted or concealed to serve a political agenda."

(Kurt Gottfried is a cofounder of the Union of Concerned Scientists and chair of its board of directors. He is professor of physics emeritus at Cornell University. Harold Varmus is president of the Memorial Sloan-Kettering Cancer Center, a cochair of the President's Council of Advisors on Science and Technology, and a former director of the National Institutes of Health.)

How stress triggers inflammation

Acute stress seems to amplify inflammatory disease despite the fact many stress hormones such as cortisol actually suppress the immune system. Qing et al. show that this is because the rise in adrenaline (epinephrine) and norepinephrine levels during acute stress triggers the release of the pro-inflammatory cytokine interleukin-6 (IL-6) by brown fat cells. IL-6 is the signal for liver release of the glucose needed for the fight or flight response, but this comes at the cost of enhancing mortality to a subsequent inflammatory challenge. Here is their abstract:

Highlights

• IL-6 is the dominant endocrine cytokine induced by acute stress in mice

• Stress-inducible IL-6 is produced in brown adipocytes via ADRB3 signaling

• IL-6 is required for stress hyperglycemia and adaptive “fight or flight” responses

• Stress-induced IL-6 decreases tolerance to a subsequent inflammatory challenge

Summary

Acute psychological stress has long been known to decrease host fitness to inflammation in a wide variety of diseases, but how this occurs is incompletely understood. Using mouse models, we show that interleukin-6 (IL-6) is the dominant cytokine inducible upon acute stress alone. Stress-inducible IL-6 is produced from brown adipocytes in a beta-3-adrenergic-receptor-dependent fashion. During stress, endocrine IL-6 is the required instructive signal for mediating hyperglycemia through hepatic gluconeogenesis, which is necessary for anticipating and fueling “fight or flight” responses. This adaptation comes at the cost of enhancing mortality to a subsequent inflammatory challenge. These findings provide a mechanistic understanding of the ontogeny and adaptive purpose of IL-6 as a bona fide stress hormone coordinating systemic immunometabolic reprogramming. This brain-brown fat-liver axis might provide new insights into brown adipose tissue as a stress-responsive endocrine organ and mechanistic insight into targeting this axis in the treatment of inflammatory and neuropsychiatric diseases.

 Another of my old posts, from March 18, 2009:

My thanks to friend Mark Weber for bringing this satire to my attention.

Nearest neighbors shape educational attainment regardless of class origin.

From Hedefalk and Dribe:

Significance

Much neighborhood research has focused on contemporary and segregated cities in the United States, but less on small and more homogenous cities. Additionally, neighborhood conditions are often estimated using administrative borders, which bias results. We adopt a long-term perspective on the importance of childhood neighbors, using more realistic methods of neighborhood conditions. We estimate individual neighborhoods at the address level, using geocoded longitudinal microdata (1939 to 2015) for a medium-sized Swedish town. We show that even when growing up in an economically relatively equal population, when higher education expanded greatly, the social class of the nearest childhood neighbors was important for educational achievements, regardless of social class and schools. Associations are strongest for boys, but with similar patterns across genders.

Abstract

We study the association between sociospatial neighborhood conditions throughout childhood and educational attainment in adulthood. Using unique longitudinal microdata for a medium-sized Swedish town, we geocode its population at the address level, 1939 to 1967, and link individuals to national registers, 1968 to 2015. Thus, we adopt a long-term perspective on the importance of nearby neighbors during a period when higher education expanded. Applying a method for estimating individual neighborhoods at the address level, we analyze the association between the geographically weighted social class of the nearest 6 to 100 childhood neighbors (ages 2 to 17), and the likelihood of obtaining a university degree by age 40, controlling for both family social class and school districts. We show that even when growing up in a town with relatively low economic inequality, the social class of the nearest same-age neighbors in childhood was associated with educational attainment, and that the associations were similar regardless of class origin. Growing up in low-class neighborhoods lowered educational attainment; growing up in high-class neighborhoods increased attainment. Social class and neighborhoods reinforced each other, implying that high-class children clustered with each other had much higher odds of obtaining a university degree than low-class children from low-class neighborhoods. Thus, even if all groups benefited from the great expansion of free higher education in Sweden (1960s to 1970s), the large inequalities between the classes and neighborhoods remained unchanged throughout the period. These findings show the importance of an advantageous background, both regarding the immediate family and the networks of nearby people of the same age.

An interlude of Grieg's Lyric Pieces

Almost every afternoon around 4 p.m. I open up my Steinway B and read some piano scores stored on my iPad. It takes very little effort to do a video of the playing using my iPhone with a small condenser microphone plugged into its usb port. Here are a few of the starting pieces in Grieg's Lyric Pieces series.

Lower socioeconomic status and the acceleration of aging.

An analysis from Steptoe and Zaninotto, who show that lower wealth correlates with accelerated aging independently of the presence of health conditions:

Significance

Lower socioeconomic status (SES) is a determinant of many of the health problems that emerge at older ages. The extent to which lower SES is associated with faster decline in age-related functions and phenotypes independently of health conditions is less clear. This study demonstrates that lower SES (defined by wealth) is related to accelerated decline over 6 to 8 y in 16 outcomes from physical, sensory, physiological, cognitive, emotional, and social domains, independently of diagnosed health conditions, self-rated health, education, and other factors. It provides evidence for the pervasive role of social circumstances on core aging processes and suggests that less affluent sectors of society age more rapidly than more privileged groups.

Abstract

Aging involves decline in a range of functional abilities and phenotypes, many of which are also associated with socioeconomic status (SES). Here we assessed whether lower SES is a determinant of the rate of decline over 8 y in six domains—physical capability, sensory function, physiological function, cognitive performance, emotional well-being, and social function—in a sample of 5,018 men and women aged 64.44 (SD 8.49) y on average at baseline. Wealth was used as the marker of SES, and all analyses controlled for age, gender, ethnicity, educational attainment, and long-term health conditions. Lower SES was associated with greater adverse changes in physical capability (grip strength, gait speed, and physical activity), sensory function (sight impairment), physiological function (plasma fibrinogen concentration and lung function), cognitive performance (memory, executive function, and processing speed), emotional well-being (enjoyment of life and depressive symptoms), and social function (organizational membership, number of close friends, volunteering, and cultural engagement). Effects were maintained when controlling statistically for other factors such as smoking, marital/partnership status, and self-rated health and were also present when analyses were limited to participants aged ≤75 y. We conclude that lower SES is related to accelerated aging across a broad range of functional abilities and phenotypes independently of the presence of health conditions and that social circumstances impinge on multiple aspects of aging.

Exaggerated meta-perceptions predict intergroup hostility between American political partisans

An interesting study from Moore-Berg et al. showing that Democrats think (have the meta-perception) that Republicans view them more negatively than they actually do, and vice versa. The bottom line is that "partisan meta-perceptions are subject to a strong negativity bias with Democrats and Republicans agreeing that the shadow of partisanship is much larger than it actually is, which fosters mutual intergroup hostility."

Significance

Although much current research highlights differences between political partisans, our research provides evidence that strong partisan biases in meta-perceptions are largely symmetrical for Democrats and Republicans. This suggests that biased meta-perceptions are a consequence of shared psychology rather than merely a consequence of divergent ideological convictions. Meta-perceptions represent evaluations that are distinct from perceptions at a core psychological level: While negative perceptions, such as dehumanization, can be thought of as offensive or reprehensible, meta-perceptions are inferences about what others think and can, therefore, be false. The theoretical distinctions between perceptions and meta-perceptions suggest that practical approaches to reducing negative meta-perceptions may be distinct from those that aim to reduce negative perceptions.

Abstract

People’s actions toward a competitive outgroup can be motivated not only by their perceptions of the outgroup, but also by how they think the outgroup perceives the ingroup (i.e., meta-perceptions). Here, we examine the prevalence, accuracy, and consequences of meta-perceptions among American political partisans. Using a representative sample (n = 1,056) and a longitudinal convenience sample (n = 2,707), we find that Democrats and Republicans equally dislike and dehumanize each other but think that the levels of prejudice and dehumanization held by the outgroup party are approximately twice as strong as actually reported by a representative sample of Democrats and Republicans. Overestimations of negative meta-perceptions were consistent across samples over time and between demographic subgroups but were modulated by political ideology: More strongly liberal Democrats and more strongly conservative Republicans were particularly prone to exaggerate meta-perceptions. Finally, we show that meta-prejudice and meta-dehumanization are independently associated with the desire for social distance from members of the outgroup party and support for policies that harm the country and flout democratic norms to favor the ingroup political party. This research demonstrates that partisan meta-perceptions are subject to a strong negativity bias with Democrats and Republicans agreeing that the shadow of partisanship is much larger than it actually is, which fosters mutual intergroup hostility.

Brain correlates of the muting of our emotions as we age.

 (This is a re-post of the MindBlog post of Oct. 1, 2008, as relevant today as then.)

My boyfriend in the early 19980’s was a pharmacy graduate student whose t-shirt read “Drugs are my life.” If I were to wear such a t-shirt now it would read “Hormones and neurotransmitters are my life.” I increasingly feel that all this verbal stuff we do - chattering in person or in the electronic ether, writing blogs, etc. - is a superficial veneer, noise on top of what is really running the show, which is the waxing and waning of hormones and neurotransmitters directed by an “it”, a martian inside us utterly running its own show. These compounds regulate our assertiveness versus passivity , our trust versus mistrust, our anxiety versus calm, our pleasure during antipication and reward. (They function, respectively, in neural systems that use testosterone, oxytocin, adrenaline, and dopamine.). The swings in these systems become less dramatic as we 'mellow' with aging.

Dreher et al. have published an interesting bit of work that deals specifically with the muting of the intensity of the pleasures we feel during anticipation and reward, in their article on “Age-related changes in midbrain dopaminergic regulation of the human reward system.” Their data show what is going on as we experience less excitement at opening a present when we are 60 than when we are 10 years old. There are changes in the brain's production of dopamine, which plays a central role in our reward system, as well as in which parts of the brain respond to it, and by how much they respond. (a recent brief article on dopamine and the reward system of the brain is here.) Here is their abstract, followed by a figure from the paper.

The dopamine system, which plays a crucial role in reward processing, is particularly vulnerable to aging. Significant losses over a normal lifespan have been reported for dopamine receptors and transporters, but very little is known about the neurofunctional consequences of this age-related dopaminergic decline. In animals, a substantial body of data indicates that dopamine activity in the midbrain is tightly associated with reward processing. In humans, although indirect evidence from pharmacological and clinical studies also supports such an association, there has been no direct demonstration of a link between midbrain dopamine and reward-related neural response. Moreover, there are no in vivo data for alterations in this relationship in older humans. Here, by using 6-[18F]FluoroDOPA (FDOPA) positron emission tomography (PET) and event-related 3T functional magnetic resonance imaging (fMRI) in the same subjects, we directly demonstrate a link between midbrain dopamine synthesis and reward-related prefrontal activity in humans, show that healthy aging induces functional alterations in the reward system, and identify an age-related change in the direction of the relationship (from a positive to a negative correlation) between midbrain dopamine synthesis and prefrontal activity. These results indicate an age-dependent dopaminergic tuning mechanism for cortical reward processing and provide system-level information about alteration of a key neural circuit in healthy aging. Taken together, our findings provide an important characterization of the interactions between midbrain dopamine function and the reward system in healthy young humans and older subjects, and identify the changes in this regulatory circuit that accompany aging.

For a tranquil start to your week, Debussy with flowers

In my slow cruising through old MindBlog posts, I just came across the following post from Monday, March 2, 2009.....perhaps a faintly calming antidote to our current uncertain times. Enjoy:

I got an email from the fellow who made this video asking if he could use my YouTube videorecording of the Debussy Reverie. I said 'sure, go ahead'.... I'm not too keen on the electronic 'enhancements' he added to my basic piano track to make the first half of the video, but here it is...

Some rambling on "Selves" and "Purpose"

I've decided to re-post the following text from a MindBlog post of Oct. 9, 2007, which I found while cruising old posts. A bit terse and disjointed, but I like the general sentiments.

Self conscious "Purpose" of the sort we humans experience, in the service of crafting new political movements or environments, is an evolved psychology that (sometimes) helps pass on our genes, and requires our distinctively human self reflective "I". Our behavior and that of other animals also reflects a kind of purpose that has been formed by our evolutionary and developmental history. In other animals such behaviors are acted out on the cusp of an eternal present - there is no evidence that they "know that they know" in the way that we can.

Both modern neuroscience and Buddhist psychology inform us that the self and the purpose that each of us experiences is an illusion or confabulation of our brains - hopefully a useful one - whose utility is tested by how it enhances our energy and individual survival. This 'illusion' is a powerful instrument of downward causation, regulating our psychological, immune, neuro-endocrine robustness.

What is especially amazing is that our human body/brain can sometimes use meditative or other techniques to bootstrap to a level of metacognition that rests antecedent to - and can be the detached observer of - the generation of this illusion of a self and its purposes.

The maximum power of our self illusion, for most of us, goes with our heartfelt immersion and belief in it (i.e., our delusion). From such a immersion, it can be more difficult to discern or appreciate the different selves and purposes of other humans, and their cultures and historical eras.

Which way are you wagging your tail?

Blakeslee writes a review (PDF here) of work by Vallortigara et al (PDF here) on emotional asymmetric tail wagging by dogs that is a further reflection of lateralized functions of the brain. Some edited clips from her article:

In most animals, including birds, fish and frogs, the left brain specializes in behaviors involving what the scientists call approach and energy enrichment. In humans, that means the left brain is associated with positive feelings, like love, a sense of attachment, a feeling of safety and calm. It is also associated with physiological markers, like a slow heart rate.

At a fundamental level, the right brain specializes in behaviors involving withdrawal and energy expenditure. In humans, these behaviors, like fleeing, are associated with feelings like fear and depression. Physiological signals include a rapid heart rate and the shutdown of the digestive system.

Because the left brain controls the right side of the body and the right brain controls the left side of the body, such asymmetries are usually manifest in opposite sides of the body. Thus many birds seek food with their right eye (left brain/nourishment) and watch for predators with their left eye (right brain/danger).

In humans, the muscles on the right side of the face tend to reflect happiness (left brain) whereas muscles on the left side of the face reflect unhappiness (right brain).

Dog tails are interesting...because they are in the midline of the dog’s body, neither left nor right. So do they show emotional asymmetry, or not?

Vallortigara et al show that when dogs were attracted to something, including a benign, approachable cat, their tails wagged right, and when they were fearful, their tails went left. It suggests that the muscles in the right side of the tail reflect positive emotions while the muscles in the left side express negative ones.

Brain asymmetry for approach and withdrawal seems to be an ancient trait..Thus it must confer some sort of survival advantage on organisms.

Animals that can do two important things at the same time, like eat and watch for predators, might be better off. And animals with two brain hemispheres could avoid duplication of function, making maximal use of neural tissue.

The asymmetry may also arise from how major nerves in the body connect up to the brain... Nerves that carry information from the skin, heart, liver, lungs and other internal organs are inherently asymmetrical, he said. Thus information from the body that prompts an animal to slow down, eat, relax and restore itself is biased toward the left brain. Information from the body that tells an animal to run, fight, breathe faster and look out for danger is biased toward the right brain.

(This is a re-posting of the MindBlog post of 4/27/2007, material as interesting and fresh today as it was then.)

Response to climate change...."Managed Retreat"

This PNAS Core Concepts article by John Carey is worth a read. Here is its beginning:

As climate change causes seas to rise and fuels ever-stronger storms and droughts, humanity faces a stark choice. Communities can seek shelter from rising waters and battering storm surges by building fortifications such as the sea walls planned in Boston or Miami. Or people can figure out how to live with the new climate reality, such as by perching homes on 10-foot stilts on the North Carolina coast to stay high and dry above surging storm waves. Or they opt for a third option that’s increasingly getting attention: “managed retreat” away from the problem area. Managed retreat is “the purposeful, coordinated movement of people and assets out of harm’s way,”

Carey notes historical examples of moving entire towns or neighborhoods to safety away from high water or highway construction...

So what’s different now? Put simply, climate change. Sea levels could climb as much as six feet or more by century’s end, inundating hundreds of coastal cities, and intense storms and floods, heat waves, and wildfires are already striking communities around the globe. Unlike in the past, the number of people who will be forced to move is likely in the hundreds of millions—more than 300 million globally by 2050 just from sea level rise alone—according to new, more precise measurements of land heights that show that more people than previously thought are living just a few feet above sea level. To meet that staggering challenge, the historical pattern of relocations—typically just a few homes at a time, largely ad hoc, and almost invariably after a disaster has left a trail of damage and destruction—is woefully inadequate, researchers say. Relocations now and in the future must be many orders of magnitude larger in number and size, and, ideally, proactive rather than reactive. That means a tremendous increase in the need for managed retreat.

Five Epic Crises All at Once - David Brooks

I've been preparing a few summaries for a meeting this coming Sunday of The Austin Rainbow Forum, a senior group that discusses current topics and ideas. The topic for the meeting is "Possible Futures - The World after Coronavirus." I thought I would pass on what I'm putting in a slide showing a truncated version of David Brooks' recent Op-Ed piece in the NYTimes. His five epic crises:

1 - we are losing the fight against Covid-19. Our behavior doesn’t have anything to do with the reality around us. We just got tired so we’re giving up.

2 - Americans... are undergoing a rapid education on the burdens African-Americans carry every day...already public opinion is shifting with astonishing speed.

3 - we’re in the middle of a political realignment. The American public is vehemently rejecting Donald Trump’s Republican Party.

4 - a quasi-religion, Social Justice, is seeking control of America’s cultural institutions...Viewpoints are not explorations of truth, but weapons that dominant groups use to maintain their place in the power structure. Words can thus be a form of violence that has to be regulated.

5 - we are on the verge of a prolonged economic depression.

The Social Justice methodology is ultimately not a solution to our problem, it’s a symptom of our problem. Over the last half century, we’ve turned politics from a practical way to solve common problems into a cultural arena to display resentments. Donald Trump is the ultimate performer in this paralyzed arena.

...thank God that Joe Biden is going to be nominated by the Democratic Party. He came to public life when it wasn’t about performing your zeal, it was about crafting coalitions and legislating. He exudes a spirit that is about empathy and friendship not animosity and canceling. The pragmatic spirit of the New Deal is a more apt guide for the years ahead than the spirit of critical theory symbology.

Feeling bad is not bad.

MindBlog is passing on the link to each of Arthur Brooks' biweekly articles in his series "How to Build a Life". This latest installment deals with negative emotions, using them to grow and develop resilience rather than pushing them away. It is more difficult to summarize in a tidy way as I have some previous installments in the series. I suggest you read the whole piece. I will note the last two paragraphs:

One last thought: In 2019, the comedian Stephen Colbert was asked in an interview by CNN’s Anderson Cooper about a plane crash that killed Colbert’s father and two of his brothers when he was 10 years old. Cooper quoted a previous statement by Colbert that he had learned to “love the thing that I most wish had not happened.” He asked Colbert to clarify this extraordinary remark. “It’s a gift to exist, and with existence comes suffering,” Colbert replied. “I don’t want it to have happened … but if you are grateful for your life … then you have to be grateful for all of it. You can’t pick and choose what you’re grateful for.”

Colbert’s words resonated deeply with me, and perhaps they do with you, too. No normal person skips merrily into a tragic loss, nor usually seeks out even minor discomfort. But those things find us, over and over again in life. This is especially true today, in the era of COVID-19. The meaning from this pain, and the benefits it can bring to our lives and society, comes from how we choose to use it.

MindBlog's half-sour pickle recipe

This posting falls under the "random curious stuff" category mentioned in the title box of this blog. At the social/musical at my Twin Valley home on June 29*, several people asked for the recipe for the half-sour pickles we had served with gazpacho as a garnish. Here it is, the result of several trials to get them the way I like them. Not guaranteed to please all....

Deric's final half sour pickle recipe:

-2 lbs pickling cucumbers
-1 bundle of dill heads and stalks
-Wash cukes and dill, cut dill stalks to ~2-3 inch lengths, cut ends off cukes, slice cukes lengthwise if they are large.
-layer dill and cukes in container (~2 quart jar or plastic container)
-pour in water to cover, then pour this water into quart (4 cup) measuring cup to determine its volume, i.e. the desired volume for the pickling mixture to be added (should be ~ 4 cups).
-add 1/4 cup sea or kosher or pickling salt to 2 cups water, dissolve
-add 1/3 cup rice wine vinegar (or other very mild vinegar), 1/2 teaspoon whole black peppercorns, 3-4 whole coriander seeds, 1/2 teaspoon mustard seeds, 4-6 cloves fresh garlic, finely chopped.
-add water to obtain the volume determined above (~4 cups) while mixing thoroughly and pour over pickles.
-rotate jar or container at intervals to mix thoroughly, leave two days at room temperature, until a few bubbles start to appear, then put in refrigerator.
-pickles should be ready to eat after ~ 4 days, flavor improves over two weeks.

*(Note: I just made this recipe a few days ago from pickling cucumbers in our garden at my Austin Texas home.  Then I came across this post from 6/29/2008...done after a social occasional at my former Wisconsin home,  and decided to re-post it here.  As I look back over old posts during my COVID-19 mandated leisure, I notice that I used to do many more personal posts like this.)

The pandemic has put history on fast-forward.

Edited clips from Ross Douthat's NYTimes Op-Ed piece, suggesting that:

...when the coronavirus era finally ends, there will be a Rip Van Winkle feeling — a sense of having been asleep and waking to normality, except that we will have time-traveled and the normality will resemble the year 2030 as it might have been without the virus, rather than just a simple turn to 2021 or 2022.

-Key cultural institutions will have been increasingly consolidated and concentrated, academia and journalism especially

-Institutional churches will have faced falling donations and shrunken attendance, accelerating decay that awaited them with the next decade’s worth of generational turnover.

-In politics, what was likely to be a slow-motion leftward shift in politics, as the less-married, less-religious, more ethnically diverse younger generation gained more power, will have been accelerated nationally by the catastrophes of the Trump administration, putting states in play for Democrats five or 10 years early.

-In corporate America, there may have been trends toward both consolidation and dispersal. The former, because even federal intervention probably won’t prevent small businesses from going under, the second because the remote-work experience, pandemic fears and possibly-rising crime rates may encourage more companies to disperse talent back into the heartland for the first time in two generations.

...only this last one seems like a hopeful sign that post-pandemic America might become less sclerotic, less decadent than the America of 2019. If one wanted to be especially optimistic, one could add that maybe — maybe — a corporate dispersal will reduce social stratification, and help create new intellectual, journalistic and even religious centers.

Vote-by-mail has no impact on partisan turnout or vote share

Some factual data from Thompson et al. which we can be sure will be ignored by those trying to suppress voting by opposing mail in ballots:  

Significance

In response to COVID-19, many scholars and policy makers are urging the United States to expand voting-by-mail programs to safeguard the electoral process, but there are concerns that such a policy could favor one party over the other. We estimate the effects of universal vote-by-mail, a policy under which every voter is mailed a ballot in advance of the election, on partisan election outcomes. We find that universal vote-by-mail does not affect either party’s share of turnout or either party’s vote share. These conclusions support the conventional wisdom of election administration experts and contradict many popular claims in the media. Our results imply that the partisan outcomes of vote-by-mail elections closely resemble in-person elections, at least in normal times.

Abstract

In response to coronavirus disease 2019 (COVID-19), many scholars and policy makers are urging the United States to expand voting-by-mail programs to safeguard the electoral process. What are the effects of vote-by-mail? In this paper, we provide a comprehensive design-based analysis of the effect of universal vote-by-mail—a policy under which every voter is mailed a ballot in advance of the election—on electoral outcomes. We collect data from 1996 to 2018 on all three US states that implemented universal vote-by-mail in a staggered fashion across counties, allowing us to use a difference-in-differences design at the county level to estimate causal effects. We find that 1) universal vote-by-mail does not appear to affect either party’s share of turnout, 2) universal vote-by-mail does not appear to increase either party’s vote share, and 3) universal vote-by-mail modestly increases overall average turnout rates, in line with previous estimates. All three conclusions support the conventional wisdom of election administration experts and contradict many popular claims in the media.

The University Is Like a CD in the Streaming Age

Having lectured in university classrooms for about 40 years, but not since 2005, I am blown away by changes in the academy that technology has wrought since then. In an Atlantic article, Michael D. Smith, Professor of information technology and marketing at Carnegie Mellon University, describes how colleges, like the entertainment industry, will need to embrace digital services in order to survive. I pass on a few clips, and suggest you read the whole article.

Universities have long been remarkably stable institutions — so stable that in 2001, by one account, they comprised an astonishing 70 of the 85 institutions in the West that have endured in recognizable form since the 1520s...That stability has ... bred overconfidence, overpricing, and an overreliance on business models tailored to a physical world. Like ... entertainment executives did, many of us in higher education dismiss the threats that digital technologies pose to the way we work. We diminish online-learning and credentialing platforms such as Khan Academy, Kaggle, and edX as poor substitutes for the “real thing.” We can’t imagine that “our” students would ever want to take a DIY approach to their education instead of paying us for the privilege of learning in our hallowed halls. We can’t imagine “our” employers hiring someone who doesn’t have one of our respected degrees.

But we’re going to have to start thinking differently.

...this past semester, the coronavirus pandemic transformed distance learning from a quaint side product that few elite schools took seriously to a central part of our degree-granting programs. Arguments for the inherent superiority of the residential college experience will be less convincing now that we’ve conferred the same credentials—and charged the same tuition—for education delivered remotely.

Do students think their pricey degrees [from prestigious private universities] are worth the cost when delivered remotely?

The Wall Street Journal asked that question in April, and one student responded with this zinger: “Would you pay $75,000 for front-row seats to a Beyoncé concert and be satisfied with a livestream instead?”

...the core mission of higher education...in my view...is simple: As educators, we strive to create opportunities for as many students as possible to discover and develop their talents, and to use those talents to make a difference in the world.

By that measure, our current model falls short. Elite colleges talk about helping our students flourish in society, but our tuition prices leave many of them drowning in debt—or unable to enroll in the first place. We talk about creating opportunities for students, but we measure our success based on selectivity, which is little more than a celebration of the number of students we exclude from the elite-campus experience. We talk about preparing students for careers after graduation, but a 2014 Gallup survey found that only 11 percent of business leaders believed “college graduates have the skills and competencies that their workplaces need.” We talk about creating diverse campuses, but, as recent admissions scandals have made painfully clear, our admissions processes overwhelmingly favor the privileged few.

What if new technologies could allow us to understand the varied backgrounds, goals, and learning styles of our students—and provide educational material customized to their unique needs? What if we could deliver education to students via on-demand platforms that allowed them to study whenever, wherever, and whatever they desired, instead of requiring them to conform to the “broadcast” schedule of today’s education model? What if the economies of scale available from digital delivery allowed us to radically lower the price of our educational resources, creating opportunities for learners we previously excluded from our finely manicured quads? Might we discover, as the entertainment industry has, a wealth of talented individuals with valuable contributions to make who just didn’t fit into the rigid constraints of our old model?

I believe we will, but that doesn’t mean the residential university will go away. Indeed, these changes may allow universities to jettison “anti-intellectual” professional-degree programs in favor of a renewed focus on a classical liberal-arts education. But as this happens, we might discover that the market for students interested in spending four years and thousands of dollars on a broad foundation in the humanities is smaller than we believe—certainly not large enough to support the 5,000 or so college campuses in the United States today. Soon, residential colleges may experience a decline similar to that of live theaters after the advent of movies and broadcast television. Broadway and local playhouses still exist, but they are now considered exclusive and expensive forms of entertainment, nowhere near the cultural force they once were.

But remember, just because new technology changed the way entertainment was delivered doesn’t mean it impeded the industry’s underlying mission. Instead of destroying TV, movies, and books, new technologies have produced an explosion in creative output, delivered through the convenience, personalization, and interactivity of Kindle libraries, Netflix recommendations, and Spotify playlists. Despite—or maybe because of—the digital disruption we’ve recently lived through, we’re now enjoying a golden age of entertainment.

Whether we like it or not, big changes are coming to higher education. Instead of dismissing them or denying that they’re happening, let’s embrace them and see where they can take us. We have a chance today to reimagine an old model that has fallen far behind the times. If we do it right, we might even usher in a new golden age of education.

MindBlog statistics.

I'm a complete dunce at paying attention to or understanding the number of people who make use of Deric's Mindblog, which started in 2006. Yesterday I clicked on "analytics" in the blogger platform I use (the bottom graphic), and also looked at what feedburner.google.com says about traffic at mindblog.dericbownds.net (the top two graphics). In the all time history the latter reports ~5.5 million page views, while the former reports ~1.8 million. Whatever.... I'm doing this post to show these numbers for my future reference (click to enlarge figure).
