Abundant food for thought for professionals of all types as well as students of decision science and behavioral economics.
A sprawling study of errors in decision-making, some literal matters of life and death.
You go to a doctor complaining of chest pains. The doctor orders an angiogram. The hospital requires a second opinion before authorizing surgery, and the second doctor disagrees on the extent to which a specific blood vessel is blocked. These unpredictable disagreements over the same data are what Kahneman, Sibony, and Sunstein call “noise,” a species of human error that happens whenever such higher-order judgments are involved. Noise, they write, is rampant in medicine, where “different doctors make different judgments about whether patients have skin cancer, breast cancer, tuberculosis, pneumonia, depression, and a host of other conditions.” Noise is especially prevalent in psychiatry, they add, where subjective opinion is more pronounced than in other disciplines. A cousin of bias, noise is difficult to isolate and correct. In forensic science, the authors write, noise is implicated in nearly half of all misidentifications of perpetrators and wrongful imprisonments. Unlike some categories of error, noise is often not helped by the introduction of more information. Writing in often dense but generally nontechnical prose, the authors offer strategies for reducing noise. One is to average out predictions in, say, stock market performance, since “noise is inherently statistical.” Another is to consult the smartest people you can find; while they may not be flawless, “picking those with highest mental ability makes a lot of sense.” Since error combines with snap decisions, the authors endorse rigorous review and other strategies for noise reduction and “decision hygiene” as well as developing habits of mind that acknowledge both bias and error and favor examining the opinions of those with whom one disagrees as dispassionately and fairly as possible. “To improve the quality of our judgments,” they urge, “we need to overcome noise as well as bias.”

BOOK REVIEW
Perhaps not magic but appealing nonetheless.
Want to get ahead in business? Consult a dictionary.
By Wharton School professor Berger’s account, much of the art of persuasion lies in the art of choosing the right word. Want to jump ahead of others waiting in line to use a photocopy machine, even if they’re grizzled New Yorkers? Throw a because into the equation (“Excuse me, I have five pages. May I use the Xerox machine, because I’m in a rush?”), and you’re likely to get your way. Want someone to do your copying for you? Then change your verbs to nouns: not “Can you help me?” but “Can you be a helper?” As Berger notes, there’s a subtle psychological shift at play when a person becomes not a mere instrument in helping but instead acquires an identity as a helper. It’s the little things, one supposes, and the author offers some interesting strategies that eager readers will want to try out. Instead of alienating a listener with the omniscient should, as in “You should do this,” try could instead: “Well, you could…” induces all concerned “to recognize that there might be other possibilities.” Berger’s counsel that one should use abstractions contradicts his admonition to use concrete language, and it doesn’t help matters to say that each is appropriate to a particular situation, while grammarians will wince at his suggestion that a nerve-calming exercise to “try talking to yourself in the third person (‘You can do it!’)” in fact invokes the second person. Still, there are plenty of useful insights, particularly for students of advertising and public speaking. It’s intriguing to note that appeals to God are less effective in securing a loan than a simple affirmative such as “I pay all bills…on time”), and it’s helpful to keep in mind that “the right words used at the right time can have immense power.”

A psychologist and Nobel Prize winner summarizes and synthesizes the recent decades of research on intuition and systematic thinking.
The author of several scholarly texts, Kahneman (Emeritus Psychology and Public Affairs/Princeton Univ.) now offers general readers not just the findings of psychological research but also a better understanding of how research questions arise and how scholars systematically frame and answer them. He begins with the distinction between System 1 and System 2 mental operations, the former referring to quick, automatic thought, the latter to more effortful, overt thinking. We rely heavily, writes, on System 1, resorting to the higher-energy System 2 only when we need or want to. Kahneman continually refers to System 2 as “lazy”: We don’t want to think rigorously about something. The author then explores the nuances of our two-system minds, showing how they perform in various situations. Psychological experiments have repeatedly revealed that our intuitions are generally wrong, that our assessments are based on biases and that our System 1 hates doubt and despises ambiguity. Kahneman largely avoids jargon; when he does use some (“heuristics,” for example), he argues that such terms really ought to join our everyday vocabulary. He reviews many fundamental concepts in psychology and statistics (regression to the mean, the narrative fallacy, the optimistic bias), showing how they relate to his overall concerns about how we think and why we make the decisions that we do. Some of the later chapters (dealing with risk-taking and statistics and probabilities) are denser than others (some readers may resent such demands on System 2!), but the passages that deal with the economic and political implications of the research are gripping.
