Neuroscientist Sees Entrepreneurs as “Never Satisfied” Due to “Attenuated Dopamine Function”

David J. Linden is the author of The Compass of Pleasure and a Johns Hopkins University School of Medicine Professor of Neuroscience.

(p. 4) . . . , the psychological profile of a compelling leader — think of tech pioneers like Jeff Bezos, Larry Ellison and Steven P. Jobs — is also that of the compulsive risk-taker, someone with a high degree of novelty-seeking behavior. In short, what we seek in leaders is often the same kind of personality type that is found in addicts, whether they are dependent on gambling, alcohol, sex or drugs.

How can this be? We typically see addicts as weak-willed losers, and chief executives and entrepreneurs are people with discipline and fortitude. To understand this apparent contradiction we need to look under the hood of the brain, and in particular at the functions that relate to pleasure and reward.
. . .
Crucially, genetic variants that suppress dopamine signaling in the pleasure circuit substantially increase pleasure- and novelty-seeking behaviors — their bearers must seek high levels of stimulation to reach the same level of pleasure that others can achieve with more moderate indulgence. Those blunted dopamine receptor variants are associated with substantially increased risk of addiction to a range of substances and behaviors.
. . .
The risk-taking, novelty-seeking and obsessive personality traits often found in addicts can be harnessed to make them very effective in the workplace. For many leaders, it’s not the case that they succeed in spite of their addiction; rather, the same brain wiring and chemistry that make them addicts also confer on them behavioral traits that serve them well.
So, when searching for your organization’s next leader, look for someone with an attenuated dopamine function: someone who is never satisfied with the status quo, someone who wants the feeling of success more than others — but likes it less.

We Tend to Ignore Information that Contradicts Our Beliefs

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

We learn the most when our priors are contradicted. But the dissonance between evidence and beliefs is painful. So we often do not see, or soon forget, evidence that does not fit with our beliefs.
The innovative entrepreneur is often a person who sees and forces herself to remember, the dissonant fact, storing it away to make sense of, or make use of, later. At the start, she may be alone in what she sees and what she remembers. So if we are to benefit from her ability and willingness to bear the pain of dissonance, she must have the freedom to differ, and she must have the financial wherewith-all to support herself until her vision is more widely shared, better understood, and more fruitfully applied.

(p. A13) Beliefs come first; reasons second. That’s the insightful message of “The Believing Brain,” by Michael Shermer, the founder of Skeptic magazine. In the book, he brilliantly lays out what modern cognitive research has to tell us about his subject–namely, that our brains are “belief engines” that naturally “look for and find patterns” and then infuse them with meaning. These meaningful patterns form beliefs that shape our understanding of reality. Our brains tend to seek out information that confirms our beliefs, ignoring information that contradicts them. Mr. Shermer calls this “belief-dependent reality.” The well-worn phrase “seeing is believing” has it backward: Our believing dictates what we’re seeing.
. . .
One of the book’s most enjoyable discussions concerns the politics of belief. Mr. Shermer takes an entertaining look at academic research claiming to prove that conservative beliefs largely result from psychopathologies. He drolly cites survey results showing that 80% of professors in the humanities and social sciences describe themselves as liberals. Could these findings about psychopathological conservative political beliefs possibly be the result of the researchers’ confirmation bias?
As for his own political bias, Mr. Shermer says that he’s “a fiscally conservative civil libertarian.” He is a fan of old-style liberalism, as in liberality of outlook, and cites “The Science of Liberty” author Timothy Ferris’s splendid formulation: “Liberalism and science are methods, not ideologies.” The “scientific solution to the political problem of oppressive governments,” Mr. Shermer says, “is the tried-and-true method of spreading liberal democracy and market capitalism through the open exchange of information, products, and services across porous economic borders.”
But it is science itself that Mr. Shermer most heartily embraces. “The Believing Brain” ends with an engaging history of astronomy that illustrates how the scientific method developed as the only reliable way for us to discover true patterns and true agents at work. Seeing through a telescope, it seems, is believing of the best kind.

In Medicine, as Elsewhere, What Pays Is Usually What Gets Done

“”I had to train myself not to get too interested in their problems, and not to get sidetracked trying to be a semi-therapist.” Dr. Donald Levin, a psychiatrist whose practice no longer includes talk therapy.” Source of caption and photo: online version of the NYT article quoted and cited below.

(p. A1) DOYLESTOWN, Pa. — Alone with his psychiatrist, the patient confided that his newborn had serious health problems, his distraught wife was screaming at him and he had started drinking again. With his life and second marriage falling apart, the man said he needed help.

But the psychiatrist, Dr. Donald Levin, stopped him and said: “Hold it. I’m not your therapist. I could adjust your medications, but I don’t think that’s appropriate.”
Like many of the nation’s 48,000 psychiatrists, Dr. Levin, in large part because of changes in how much insurance will pay, no longer provides talk therapy, the form of psychiatry popularized by Sigmund Freud that dominated the profession for decades. Instead, he prescribes medication, usually after a brief consultation with each patient. So Dr. Levin sent the man away with a referral to a less costly therapist and a personal crisis unexplored and unresolved.

Study Hard to Study Well

(p. D6) In a recent study published in the journal Cognition, psychologists at Princeton and Indiana University had 28 men and women read about three species of aliens, each of which had seven characteristics, like “has blue eyes,” and “eats flower petals and pollen.” Half the participants studied the text in 16-point Arial font, and the other half in 12-point Comic Sans MS or 12-point Bodoni MT, both of which are relatively unfamiliar and harder for the brain to process.
After a short break, the participants took an exam, and those who had studied in the harder-to-read fonts outperformed the others on the test, 85.5 percent to 72.8 percent, on average.
To test the approach in the classroom, the researchers conducted a large experiment involving 222 students at a public school in Chesterland, Ohio. One group had all its supplementary study materials, in English, history and science courses, reset in an unusual font, like Monotype Corsiva. The others studied as before. After the lessons were completed, the researchers evaluated the classes’ relevant tests and found that those students who’d been squinting at the stranger typefaces did significantly better than the others in all the classes — particularly in physics.
“The reason that the unusual fonts are effective is that it causes us to think more deeply about the material,” a co-author of the study, Daniel M. Oppenheimer, a psychologist at Princeton, wrote in an e-mail. “But we are capable of thinking deeply without being subjected to unusual fonts. Think of it this way, you can’t skim material in a hard to read font, so putting text in a hard-to-read font will force you to read more carefully.”
Then again, so will raw effort, he and other researchers said. Concentrating harder. Making outlines from scratch. Working through problem sets without glancing at the answers. And studying with classmates who test one another.

“A Lonely Ghost Uttering a Truth that Nobody Would Ever Hear”

(p. 26) He was a lonely ghost uttering a truth that nobody would ever hear. But so long as he uttered it, in some obscure way the continuity was not broken. It was not by making yourself heard but by staying sane that you carried on the human heritage.

“A Dart-Throwing Chimpanzee” Predicts as Well as “Experts”

The image is of the Canadian edition, which has a different subtitle than the American edition cited below. Source of book image: http://3.bp.blogspot.com/_qGSiMLu6NXM/TTWIQkcllmI/AAAAAAAADEI/qD2yo1rxnL0/s1600/Future%2BBabble.jpg

(p. C6) How bad are expert predictions? Almost predictably bad. In 2005, Philip Tetlock, a professor of psychology at the University of Pennsylvania, published the results of a magisterial 20-year analysis of 27,450 judgments about the future from 284 experts. He discovered that the experts, in aggregate, did little better, and sometimes considerably worse, than “a dart-throwing chimpanzee.”

While Mr. Tetlock guaranteed anonymity to get his experts to reveal how useless they were, Mr. Gardner names names. In the late 1960s, he notes, the political scientist Andrew Hacker predicted that race relations in America would soon get so bad that they would lead to the “dynamiting of bridges and water mains” and the “assassinating of public officials and private luminaries.” In the early 1970s, Richard Falk, at Princeton, imagined that by the 1990s we would be living in a world dominated by “the politics of catastrophe.” In the mid-1970s, Daniel Bell and other analysts assumed that high levels of inflation were, as Mr. Gardner puts it, “here to stay.” (In fact, inflation cooled off in the early 1980s and has stayed low for decades.) In the early 1990s, Lester Thurow, the MIT economist, was one of the experts who predicted that Japan would dominate the 21st century, though he noted that Europe had a chance, too.
The high priest of erroneous prediction is, of course, Paul Ehrlich, who, though a respected entomologist, turned into an end-of-the-worlder with “The Population Bomb” (1968) and “The End of Affluence” (1974). In the latter book he wrote: “If I were a gambler, I would take even money that England will not exist in the year 2000.” Now 77, Mr. Ehrlich is “a gregarious and delightful man, a natural performer,” Mr. Gardner reports, thereby tapping into the sources of his success in the face of repeated failure: Never admit mistakes, never sound doubtful. As Mr. Gardner shows in his survey of expert prediction-making, the more you sound like you know what you are talking about, the more people will believe you.

Hillary Clinton Blasted “Materialism” in Others and Bought a $1.7 Million House for Herself

(p. 145) . . . , it is standard to denounce materialism in others while lusting for it ourselves. At the end of the 1990s, Hillary Rodham Clinton decried “a consumer-driven culture that promotes values that undermine democracy” and blasted “materialism that undermines our spiritual centers.” Shortly thereafter, she bought a $1.7 million home and signed an $8 million book contract. As the novelist Daniel Akst has noted, Rodham Clinton thus joined the long line of commentators “bent on saving the rest of us from the horrors of consumption” while taking care to make themselves rich and comfy.

“When We Get ‘Out of Book,’ We Are at Our Most Human”

Source of book image: http://www.turingfilm.com/wp-content/uploads/2011/03/11-3-18-The-Most-Human-Human.jpg

To be an innovative entrepreneur is to “get out of book” in the language well-expressed below.

(p. A17) In chess, computers are strongest in the parts of the game in which human players rely most on memory: the opening and closing sequences. (Serious players learn strategies by rote, and the early stages of even grandmaster games contain few surprises for the cognoscenti.) Knowledge of these tried and tested moves is called “the book.” By the middle section of a game, however, the number of permutations of moves is too vast for memorization to help. Here players need to get “out of book” and act unexpectedly, which is why computers–even Deep Blue–can struggle.

Mr. Christian elaborates on this distinction and applies it to human intelligence in general. For isn’t it precisely when people refuse to get “out of book”–just following orders or playing their role–that we find them least human? Likewise, when we get “out of book,” we are at our most human. Think of the difference between the waiter who runs through the usual routine and the one who responds to your order with a witticism. Remaining alive to what is mechanical or original in our own behavior can preserve a sense of human difference.

Academic Psychologists Create Hostile Climate for Non-Liberals

(p. D1) SAN ANTONIO — Some of the world’s pre-eminent experts on bias discovered an unexpected form of it at their annual meeting.

Discrimination is always high on the agenda at the Society for Personality and Social Psychology’s conference, where psychologists discuss their research on racial prejudice, homophobia, sexism, stereotype threat and unconscious bias against minorities. But the most talked-about speech at this year’s meeting, which ended Jan. 30, involved a new “outgroup.”
It was identified by Jonathan Haidt, a social psychologist at the University of Virginia who studies the intuitive foundations of morality and ideology. He polled his audience at the San Antonio Convention Center, starting by asking how many considered themselves politically liberal. A sea of hands appeared, and Dr. Haidt estimated that liberals made up 80 percent of the 1,000 psychologists in the ballroom. When he asked for centrists and libertarians, he spotted fewer than three dozen hands. And then, when he asked for conservatives, he counted a grand total of three.
“This is a statistically impossible lack of diversity,” Dr. Haidt concluded, noting polls showing that 40 percent of Americans are conservative and 20 percent are liberal. In his speech and in an interview, Dr. Haidt argued that social psychologists are a “tribal-moral community” united by “sacred values” that hinder research and damage their credibility — and blind them to the hostile climate they’ve created for non-liberals.
. . .
(p. D3) The politics of the professoriate has been studied by the economists Christopher Cardiff and Daniel Klein and the sociologists Neil Gross and Solon Simmons. They’ve independently found that Democrats typically outnumber Republicans at elite universities by at least six to one among the general faculty, and by higher ratios in the humanities and social sciences. In a 2007 study of both elite and non-elite universities, Dr. Gross and Dr. Simmons reported that nearly 80 percent of psychology professors are Democrats, outnumbering Republicans by nearly 12 to 1.

“Inventors Are Sometimes Beneficiaries of Their Own Ignorance”

William Rosen gives us a thought-provoking anecdote about Edmund Cartwright, the inventor of the first power loom:

(p. 238) He was also, apparently, convinced of the practicality of such a machine by the success of the “Mechanical Turk,” a supposed chess-playing robot that had mystified all of Europe and which had not yet been revealed as one of the era’s great hoaxes: a hollow figurine concealing a human operator. Inventors are sometimes beneficiaries of their own ignorance.

“Inventors Fear Wrong Answers Less than Noninventors”

(p. 123) [A] . . . study . . . conducted in 1962, compared the results of psychometric tests given to inventors and noninventors (the former defined by behaviors such as application for or receipt of a patent) in similar professions, such as engineers, chemists, architects, psychologists, and science teachers. Some of the results (p. 124) were about what one might expect: inventors are significantly more thing-oriented than people-oriented, more detail-oriented than holistic. They are also likely to come from poorer families than noninventors in the same professions. . . .
. . . , the 1962 study also revealed that independent inventors scored far lower on general intelligence tests than did research scientists, architects, or even graduate students. There’s less to this than meets the eye: The intelligence test that was given to the subjects subtracted wrong answers from right answers, and though the inventors consistently got as many answers correct as did the research scientists, they answered far more questions, thereby incurring a ton of deductions. While the study was too small a sample to prove that inventors fear wrong answers less than noninventors, it suggested just that. In the words of the study’s authors, “The more inventive an independent inventor is, the more disposed he will be–and this indeed to a marked degree–to try anything that might work.”
