ROCK BREAKS SCISSORS

A PRACTICAL GUIDE TO OUTGUESSING AND OUTWITTING ALMOST EVERYBODY

An ingenious guide to outsmarting others by predicting their choices when they are trying to be unpredictable.

Being predictable is difficult, writes business and science writer Poundstone (Are You Smart Enough to Work at Google?, 2012, etc.). When taking tests in which they are asked to write a series of random numbers, almost everyone avoids repeats such as 4444, but true randomness requires them. The authors of these tests fall into this trap, so if a correct answer in a true-false test is true, the following is more likely to be false and vice versa. If doubt remains, guess true, since 56 percent of true-false answers are true. Test authors must invent many wrong answers for every right one, and it’s tempting to use shortcuts. The easiest is to insert “never,” “always,” “all” or “none,” into a reasonable statement. Never choose these. On the other hand, if one answer is “all of the above” or “none of the above,” the test author must carefully write the other answers around them, so why waste all that work? These are correct an astonishing 52 percent of the time. Many genuine insights on gambling, betting pools and the stock market have limited appeal, but the string of surprises continues. Thus, hot streaks (consecutive wins in any sport and other examples) occur as often as they do in roulette. In other words, they’re purely random. “All of this book’s applications are founded on one simple idea,” writes the author. “When people make arbitrary, random, or strategic choices, they fall into unconscious patterns that you can predict.”

Malcolm Gladwell’s Outliers (2008) and Nassim Nicholas Taleb’s The Black Swan (2007) fascinated readers with evidence that reality regularly contradicts common sense. Poundstone delivers modestly useful advice for taking advantage of this, but mostly his book is another delightful addition to the everything-you-thought-you-knew-is-wrong genre.

THINKING, FAST AND SLOW

Striking research showing the immense complexity of ordinary thought and revealing the identities of the gatekeepers in our...

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.

Striking research showing the immense complexity of ordinary thought and revealing the identities of the gatekeepers in our minds.

MASTERY

Readers unfamiliar with the anecdotal material Greene presents may find interesting avenues to pursue, but they should...

Greene (The 33 Strategies of War, 2007, etc.) believes that genius can be learned if we pay attention and reject social conformity.

The author suggests that our emergence as a species with stereoscopic, frontal vision and sophisticated hand-eye coordination gave us an advantage over earlier humans and primates because it allowed us to contemplate a situation and ponder alternatives for action. This, along with the advantages conferred by mirror neurons, which allow us to intuit what others may be thinking, contributed to our ability to learn, pass on inventions to future generations and improve our problem-solving ability. Throughout most of human history, we were hunter-gatherers, and our brains are engineered accordingly. The author has a jaundiced view of our modern technological society, which, he writes, encourages quick, rash judgments. We fail to spend the time needed to develop thorough mastery of a subject. Greene writes that every human is “born unique,” with specific potential that we can develop if we listen to our inner voice. He offers many interesting but tendentious examples to illustrate his theory, including Einstein, Darwin, Mozart and Temple Grandin. In the case of Darwin, Greene ignores the formative intellectual influences that shaped his thought, including the discovery of geological evolution with which he was familiar before his famous voyage. The author uses Grandin's struggle to overcome autistic social handicaps as a model for the necessity for everyone to create a deceptive social mask.

Readers unfamiliar with the anecdotal material Greene presents may find interesting avenues to pursue, but they should beware of the author's quirky, sometimes misleading brush-stroke characterizations.
