Shedding Light, or “The Greatest Symbol of Modern Progress”

Source of book image: http://www.vtmagazine.vt.edu/fall06/news.html

(p. 5) IN the wake of widespread violence during the New York City blackout of 1977, a newspaper columnist quipped that just one flick of a light switch separated civilization from primordial chaos.

Leaving the hyperbole aside, artificial illumination has arguably been the greatest symbol of modern progress. By making nighttime infinitely more inviting, street lighting — gas lamps beginning in the early 1800s followed by electric lights toward the end of the century — drastically expanded the boundaries of everyday life to include hours once shrouded in darkness. Today, any number of metropolitan areas in the United States and abroad, bathed in the glare of neon and mercury vapor, bill themselves as 24-hour cities, open both for business and pleasure.
. . .
. . . there was never any question that 19th-century communities welcomed lamps, which in conjunction with police forces, posed a powerful deterrent to lawlessness. Another benefit lay in the numerous pedestrians drawn by their inviting glow, whose very presence helped to discourage crime.
“As safe and agreeable to walk out in the evening as by day-light,” pronounced a New Yorker in 1853.
Certainly, public anxiety over the recent removal of lamps should not be minimized. No longer are there witches and wolves to fear, but research strongly suggests, as one might expect, the critical value of street lighting as a hindrance to crime and serious accidents.
. . .
Financial costs and public safety, however, are not the only issues. Without the benefit of street lighting, towns and cities, after sunset, will be diminished as communities. Families will be more apt to “cocoon” at home, rather than visit friends or attend sporting and cultural events. And, too, our appreciation for night itself will suffer. Evenings can be best enjoyed if they remain inviting and safe, whether for neighborhood gatherings, walking Fido or gazing at the heavens — all with less chance of losing your wallet or stumbling into a ditch.

Intuitive Expertise Develops Best When Feedback Is Clear and Fast

(p. 241) Some regularities in the environment are easier to discover and apply than others. Think of how you developed your style of using the brakes on your car. As you were mastering the skill of taking curves, you gradually learned when to let go of the accelerator and when and how hard to use the brakes. Curves differ, and the variability you experienced while learning ensures that you are now ready to brake at the right time and strength for any curve you encounter. The conditions for learning this skill arc ideal, because you receive immediate and unambiguous feedback every time you go around a bend: the mild reward of a comfortable turn or the mild punishment of some difficulty in handling the car if you brake either too hard or not quite hard enough. The situations that face a harbor pilot maneuvering large ships are no less regular, but skill is much more difficult to acquire by sheer experience because of the long delay between actions and their noticeable outcomes. Whether professionals have a chance to develop intuitive expertise depends essentially on the quality and speed of feedback, as well as on sufficient opportunity to practice.

Stewart Brand Marvels at Hippie Perfectionist Jobs’ Results

Stewart Brand. Source of photo: online version of the NYT interview quoted and cited below.

(p. 3) Stewart Brand is best known as the editor of the Whole Earth Catalog, a counterculture compendium published twice a year between 1968 and 1972 and the only catalog to win the National Book Award. Its credo, “Stay hungry. Stay foolish,” influenced many of the hippie generation, most notably Steve Jobs.
. . .
READING I’m devouring “Steve Jobs,” by Walter Isaacson. Steve’s life and interests intersected with mine a number of times, so revisiting all that in sequence is like galloping through a version of my own life, plus I get to fill in the parts of his life I wondered about. Take a hippie who is also a driven perfectionist at crafting digital tools, let him become adept at managing corporate power, and marvel at what can result. The book I’m studying line by line, and dog-earing every other page, is Steven Pinker’s “Better Angels of Our Nature.” It chronicles the dramatic decline of violence and cruelty in human affairs in every century. Now that we know that human behavior has been getting constantly gentler and fairer, how do we proceed best with that wind at our backs?

Veterinarians Can Suggest Innovative Hypotheses to Doctors

Source of book image: online version of the WSJ review quoted and cited below.

Vets face less government regulation and so are freer to rapidly innovate. They may thus be a promising source of innovative hypotheses for medical doctors.

(p. D2) Cardiologist Barbara Natterson-Horowitz made her first foray into the world of animal medicine when she was asked to treat Spitzbuben, an exceedingly cute emperor tamarin suffering from heart failure.

But first, the veterinarian at the Los Angeles Zoo warned Dr. Natterson-Horowitz: Mere eye contact with the tiny primate could trigger a potentially fatal surge of stress hormones. What she learns from that experience spurs a journey to examine the links between the human and animal condition–and the discovery that the species are closer than she ever imagined.
. . .
The authors recommend that doctors, who often look with disdain on veterinarians, go the next step and collaborate with them in a cross-disciplinary “zoobiquitous” approach–using knowledge about how animals live, die and heal to spark innovative hypothesis for advancing medicine.

When Is Intuitive Judgment Valid?

(p. 240) If subjective confidence is not to be trusted, how can we evaluate the probable validity of an intuitive judgment? When do judgments reflect true expertise? When do they display an illusion of validity? The answer comes from the two basic conditions for acquiring a skill:

an environment that is sufficiently regular to be predictable

an opportunity to learn these regularities through prolonged practice

When both these conditions are satisfied, intuitions are likely to be skilled. Chess is an extreme example of a regular environment, but bridge and poker also provide robust statistical regularities that can support skill. Physicians, nurses, athletes, and firefighters also face complex but fundamentally orderly situations. The accurate intuitions that Gary Klein has described are due to highly valid cues that the expert’s System 1 has learned to use, even if System 2 has not learned to name them. In contrast, stock pickers and political scientists who make long-term forecasts operate in a zero-validity environment. Their failures reflect the basic unpredictability of the events that they try to forecast.

Romney Right that Culture Matters for Economic Success

Source of book image: http://photo.goodreads.com/books/1172699090l/209176.jpg

In the piece quoted below, and in much of the TV media coverage, the story is spun as being that Romney offended the Palestinians. But that is not the story. The story is that Romney courageously highlighted an important, but politically incorrect, truth—culture, generally, does matter for economic performance; and Israeli culture, specifically, has encouraged economic growth.
Romney referred to an important book by the distinguished economic historian David Landes. Last school year, one of the students in my Economics of Technology seminar gave a presentation on a related Landes book. That presentation can be viewed at: http://www.amazon.com/review/R2GLBAMFCS5PXH/ref=cm_cr_pr_perm?ie=UTF8&ASIN=0521094186&linkCode=&nodeID=&tag=
I recently read another relevant book, Start-Up Nation, that directly supports Romney’s specific claim, by making the case that Israeli culture is especially congenial to entrepreneurial initiative and success.

(p. A1) JERUSALEM — Mitt Romney offended Palestinian leaders on Monday by suggesting that cultural differences explain why the Israelis are so much more economically successful than Palestinians, thrusting himself again into a volatile issue while on his high-profile overseas trip.
. . .
In the speech, Mr. Romney mentioned books that had influenced his thinking about nations — particularly “The Wealth and Poverty of Nations,” by David S. Landes, which, he said, argues that culture is the defining factor in determining the success of a society.
“Culture makes all the (p. A14) difference,” Mr. Romney said. “And as I come here and I look out over this city and consider the accomplishments of the people of this nation, I recognize the power of at least culture and a few other things.”
He added, “As you come here and you see the G.D.P. per capita, for instance, in Israel, which is about $21,000, and compare that with the G.D.P. per capita just across the areas managed by the Palestinian Authority, which is more like $10,000 per capita, you notice such a dramatically stark difference in economic vitality. And that is also between other countries that are near or next to each other. Chile and Ecuador, Mexico and the United States.”
The remarks, which vastly understated the disparities between the societies, drew a swift rejoinder from Palestinian leaders.

Simple Algorithms Predict Better than Trained Experts

(p. 222) I never met Meehl, but he was one of my heroes from the time I read his Clinical vs. Statistical Prediction: A Theoretical Analysis and a Review of the Evidence.
In the slim volume that he later called “my disturbing little book,” Meehl reviewed the results of 20 studies that had analyzed whether clinical predictions based on the subjective impressions of trained professionals were more accurate than statistical predictions made by combining a few scores or ratings according to a rule. In a typical study, trained counselors predicted the grades of freshmen at the end of the school year. The counselors interviewed each student for forty-five minutes. They also had access to high school grades, several aptitude tests, and a four-page personal statement. The statistical algorithm used only a fraction of this information: high school grades and one aptitude test. Nevertheless, the formula was more accurate than 11 of the 14 counselors. Meehl reported generally sim-(p. 223)ilar results across a variety of other forecast outcomes, including violations of parole, success in pilot training, and criminal recidivism.
Not surprisingly, Meehl’s book provoked shock and disbelief among clinical psychologists, and the controversy it started has engendered a stream of research that is still flowing today, more than fifty years after its publication. The number of studies reporting comparisons of clinical and statistical predictions has increased to roughly two hundred, but the score in the contest between algorithms and humans has not changed. About 60% of the studies have shown significantly better accuracy for the algorithms. The other comparisons scored a draw in accuracy, but a tie is tantamount to a win for the statistical rules, which are normally much less expensive to use than expert judgment. No exception has been convincingly documented.

Edison Was Great Inventor; “Jobs Was the Far Shrewder Businessman”

“Thomas Alva Edison.” Source of caption and photo: online version of the NYT article quoted and cited below.

I have not read Stross’ books on Jobs and Edison. According to some of the Amazon reviews of the Jobs book, back in 1993 Stross was much more critical of Jobs than he is in the piece below:

(p. 4) I wrote a book about Mr. Jobs in 1993.
. . .
Years later, I wrote a biography of Edison, a person whom Mr. Jobs admired. When you compare the two personalities and their careers, a few similarities emerge immediately. Both had less formal schooling than most of their respective peers. Both possessed the ability to visualize projects on a grand scale. Both followed an inner voice when making decisions. And both had terrific tempers that could make their employees quake.
. . .
Mr. Jobs was the far shrewder businessman, even if he never talked about wealth as a matter of personal interest. When Edison died, he left behind an estate valued at about $12 million, or about $180 million in today’s dollars. His friend Henry Ford had once joked that Edison was “the world’s greatest inventor and the world’s worst businessman.” Mr. Jobs was worth a commanding $6.5 billion.
Mr. Jobs was perhaps the most beloved billionaire the world has ever known. Richard Branson’s tribute captures the way people felt they could identify with Mr. Jobs’s life narrative: “So many people drew courage from Steve and related to his life story: adoptees, college dropouts, struggling entrepreneurs, ousted business leaders figuring out how to make a difference in the world, and people fighting debilitating illness. We have all been there in some way and can see a bit of ourselves in his personal and professional successes and struggles.”

Experts “Produce Poorer Predictions than Dart-Throwing Monkeys”

(p. 219) Tetlock interviewed 284 people who made their living “commenting or offering advice on political and economic trends.” He asked them to assess the probabilities that certain events would occur in the not too distant future, both in areas of the world in which they specialized and in regions about which they had less knowledge. Would Gorbachev be ousted in a coup? Would the United States go to war in the Persian Gulf? Which country would become the next big emerging market? In all, Tetlock gathered more than 80,000 predictions. He also asked the experts how they reached their conclusions, how they reacted when proved wrong, and how they evaluated evidence that did not support their positions. Respondents were asked to rate the probabilities of three alternative outcomes in every case: the persistence of the status quo, more of something such as political freedom or economic growth, or less of that thing.
The results were devastating. The experts performed worse than they would have if they had simply assigned equal probabilities to each of the three potential outcomes. In other words, people who spend their time, and earn their living, studying a particular topic produce poorer predictions than dart-throwing monkeys who would have distributed their choices evenly over the options. Even in the region they knew best, experts were not significantly better than nonspecialists.

Joe Biden’s Dad Told Him to “Get Up” in Face of Job Loss

Innovative entrepreneurs, through the process of creative destruction, provide us with wonderful new products and services. But sometimes the process also results in job loss. One response to the job loss is to shut down innovation. Another is to preach resilience. Joe Biden’s Dad said “get up.” (The clip is from a talk that Joe Biden gave to the National Press Club on August 1, 2007. The full talk is posted to the C-SPAN web site.)

A mainly similar presentation of the “get up” message is on p. xxii of Biden’s autobiography:

Alexander Field Claims 1930s Were “Technologically Progressive”

Source of book image: http://yalepress.yale.edu/images/full13/9780300151091.jpg

(p. 1) UNDERNEATH the misery of the Great Depression, the United States economy was quietly making enormous strides during the 1930s. Television and nylon stockings were invented. Refrigerators and washing machines turned into mass-market products. Railroads became faster and roads smoother and wider. As the economic historian Alexander J. Field has said, the 1930s constituted “the most technologically progressive decade of the century.”
. . .
(p. 6) The closest thing to a unified explanation for these problems is a mirror image of what made the 1930s so important. Then, the United States was vastly increasing its productive capacity, as Mr. Field argued in his recent book, “A Great Leap Forward.” Partly because the Depression was eliminating inefficiencies but mostly because of the emergence of new technologies, the economy was adding muscle and shedding fat. Those changes, combined with the vast industrialization for World War II, made possible the postwar boom.
In recent years, on the other hand, the economy has not done an especially good job of building its productive capacity. Yes, innovations like the iPad and Twitter have altered daily life. And, yes, companies have figured out how to produce just as many goods and services with fewer workers. But the country has not developed any major new industries that employ large and growing numbers of workers.
