Sway: The Irresistible Pull of Irrational Behavior [Audiobook] [Audio CD]

Why would a seasoned pilot, the head of KLM's safety program, ignore his co-pilot and attempt a takeoff in fog at an unfamiliar airport, causing the worst air disaster in history? Why did the co-pilot, who had done exactly the right thing when he reminded his captain that the flight had not been cleared for takeoff, fail to repeat his warning when the pilot pressed ahead?

The collision at Tenerife airport cost the lives of 584 people. Using that accident as their starting point, the Brafman brothers explore the psychological forces that cause people to take large risks to avoid small losses, to judge people and situations by first impressions despite subsequent inconsistent evidence, and to ignore objections from dissenters.

"Sway" is the latest in an engaging series of books like Malcolm Gladwell's "Tipping Point" and "Blink" and Steven Levitt's "Freakonomics." The Brafmans' effort is one of the best written and most approachable of the recent crop, and somehow it kept my focused attention for the duration of a cross-country flight--perhaps the authors are appealing to my irrational impulses in ways they don't let on!

Anyway, one of the most interesting parts of the book is the most reassuring. Research reveals that groups often make better decisions if there's a "blocker" or "dissenter" present--even if that person dissents for the wrong reasons. The authors describe a classic experiment in which the test subjects are led to believe they are being tested for their visual skills--three lines of different lengths are to be matched to a fourth line. The differences in line length are very obvious, so there is plainly only one correct answer. If you put the real subject in a room with several actors who are pretending to be test subjects but who have actually been instructed to give a manifestly wrong answer, most subjects in the experiment will behave in a compltely irrational manner, agreeing with the other "subjects" that lines that are obviously different are exactly the same. But if an actor playing "blocker" is added to the mix and points out that the group is wrong, the subject feels free to disagree and usually makes the right choice. This is true even if the "blocker" makes a different "wrong" choice by picking two other lines of plainly different lengths. What this experiement says for the business and political world is that organizations that "brook no dissent" (like the Bush administration) are likely to perform about as well as that ill-fated flight at Tenarife.

Back to the cockpit: pilots at Southwest and other airlines are now trained to avoid the disaster that happened at Tenerife. Pilots are taught to listed to objections from other crew members, and crew members are trained to communicate those objections in a way that enables the pilot to respond quickly and correctly.

The Brafmans approach this fascinating subject with wit and style, and they tackle other interesting problems besides the one described above: why people often judge a book by its cover (so to speak), why people insist on being treated fairly even if that means foregoing a benefit, and why audiences for the French and Russian versions of "Who Wants to be A Millionaire" behave much differently from each other and from their American counterparts.

To steal a march from the disclaimer on the back of "Sway" (which you can see above), if you decide to buy the book because of this review, "you just got swayed." But you should still give this review a "helpful" vote.
