For Inventors “Optimism Is Widespread, Stubborn, and Costly”

(p. 257) One of the benefits of an optimistic temperament is that it encourages persistence in the face of obstacles. But persistence can be costly. An impressive series of studies by Thomas Åstebro sheds light on what happens when optimists receive bad news. He drew his data from a Canadian organization–the Inventors Assistance Program–which collects a small fee to provide inventors with an objective assessment of the commercial prospects of their idea. The evaluations rely on careful ratings of each invention on 37 criteria, including need for the product, cost of production, and estimated trend of demand. The analysts summarize their ratings by a letter grade, where D and E predict failure–a prediction made for over 70% of the inventions they review. The forecasts of failure are remarkably accurate: only 5 of 411 projects that were given the lowest grade reached commercialization, and none was successful.
Discouraging news led about half of the inventors to quit after receiving a grade that unequivocally predicted failure. However, 47% of them continued development efforts even after being told that their project was hopeless, and on average these persistent (or obstinate) individuals doubled their initial losses before giving up. Significantly, persistence after discouraging advice was relatively common among inventors who had a high score on a personality measure of optimism–on which inventors generally scored higher than the general population. Overall, the return on private invention was small, “lower than the return on private equity and on high-risk securities.” More generally, the financial benefits of self-employment are mediocre: given the same qualifications, people achieve higher average returns by selling their skills to employers than by setting out on their own. The evidence suggests that optimism is widespread, stubborn, and costly.

Catherine the Great as Benevolent Despot

Source of book image: http://online.wsj.com/article/SB10001424052970204644504576653083743832432.html?KEYWORDS=Catherine+Great

(p. C3) Bereft of husband and child, a lonely Catherine began to read the histories, philosophy and literature of Greece and Rome and of the Enlightenment. Montesquieu’s “The Spirit of Laws,” which analyzed the strengths and weaknesses of despotic rule, had a powerful impact on her. She was particularly interested in his thesis that the conduct of a specific despot could partially redeem that form of rule. Thereafter, she attributed to herself a “republican soul” of the kind advocated by Montesquieu.

Voltaire, the venerated patriarch of the Enlightenment, had concluded that a despotic government might well be the best possible form of government–if it were reasonable. But to be reasonable, he said, it must be enlightened; if enlightened, it could be both efficient and benevolent. Soon after ascending to the throne, Catherine began a correspondence with Voltaire that eventually extended to hundreds of letters over more than 20 years.
. . .
Near the end of her reign Catherine was asked how she understood the “blind obedience with which her orders were obeyed.” Catherine smiled and answered, “It is not as easy as you think…. I examine the circumstances, I take advice, I consult the enlightened part of the people, and so in this way I find out what sort of effect my laws will have. And when I am already convinced in advance of good approval, then I issue my orders and have the pleasure of observing what you call blind obedience.”
Catherine died in 1796, when George Washington was finishing his second term in office. Since then, the temptations of absolute power have remained great; despots have continued to appear, afflicting people everywhere. We have learned, at enormous cost, the difficulty of combining despotism with benevolence. Few rulers have even tried. Catherine tried.

Entrepreneurs Are Optimistic About the Odds of Success

(p. 256) The chances that a small business will survive for five years in the United States are about 35%. But the individuals who open such businesses do not believe that the statistics apply to them. A survey found that American entrepreneurs tend to believe they are in a promising line of business: their (p. 257) average estimate of the chances of success for “any business like yours” was 60%–almost double the true value. The bias was more glaring when people assessed the odds of their own venture. Fully 81% of the entrepreneurs put their personal odds of success at 7 out of 10 or higher, and 33% said their chance of failing was zero.

“Planning Fallacy”: Overly Optimistic Forecasting of Project Outcomes

(p. 250) This should not come as a surprise: overly optimistic forecasts of the outcome of projects are found everywhere. Amos and I coined the term planning fallacy to describe plans and forecasts that

are unrealistically close to best-case scenarios

could be improved by consulting the statistics of similar cases

. . .
The optimism of planners and decision makers is not the only cause of overruns. Contractors of kitchen renovations and of weapon systems readily admit (though not to their clients) that they routinely make most of their profit on additions to the original plan. The failures of forecasting in these cases reflect the customers’ inability to imagine how much their wishes will escalate over time. They end up paying much more than they would if they had made a realistic plan and stuck to it.
Errors in the initial budget are not always innocent. The authors of unrealistic plans are often driven by the desire to get the plan approved–(p. 251)whether by their superiors or by a client–supported by the knowledge that projects are rarely abandoned unfinished merely because of overruns in costs or completion times. In such cases, the greatest responsibility for avoiding the planning fallacy lies with the decision makers who approve the plan. If they do not recognize the need for an outside view, they commit a planning fallacy.

“Unknown Unknowns” Will Delay Most Projects

Kahneman’s frequently-used acronym “WYSIATI,” used in the passage quoted below, means “What You See Is All There Is.”

(p. 247) On that long-ago Friday, our curriculum expert made two judgments about the same problem and arrived at very different answers. The inside view is the one that all of us, including Seymour, spontaneously adopted to assess the future of our project. We focused on our specific circumstances and searched for evidence in our own experiences. We had a sketchy plan: we knew how many chapters we were going to write, and we had an idea of how long it had taken us to write the two that we had already done. The more cautious among us probably added a few months to their estimate as a margin of error.

Extrapolating was a mistake. We were forecasting based on the informa-(p. 248)tion in front of us–WYSIATI–but the chapters we wrote first were probably easier than others, and our commitment to the project was probably then at its peak. But the main problem was that we failed to allow for what Donald Rumsfeld famously called the “unknown unknowns:’ There was no way for us to foresee, that day, the succession of events that would cause the project to drag out for so long. The divorces, the illnesses, the crises of coordination with bureaucracies that delayed the work could not be anticipated. Such events not only cause the writing of chapters to slow down, they also produce long periods during which little or no progress is made at all. The same must have been true, of course, for the other teams that Seymour knew about. The members of those teams were also unable to imagine the events that would cause them to spend seven years to finish, or ultimately fail to finish, a project that they evidently had thought was very feasible. Like us, they did not know the odds they were facing. There are many ways for any plan to fail, and although most of them are too improbable to be anticipated, the likelihood that something will go wrong in a big project is high.

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.
