Book Review: Malcolm Gladwell's Blink

RATING: (3 out of 5 Brains)

Well, as a huge fan of Gladwell's last book, The Tipping Point, I was excited last week to finally get my hands on his new effort: Blink: The Power of Thinking Without Thinking. This time around Gladwell's basic thesis is that often snap judgements (what he calls "thin slicing") can be more accurate than well researched, careful analysis. Gladwell uses many examples (most are interesting) to demonstrate this behavior such as determining when art is faked, sizing up car buyers, picking presidential candidates and determining the characteristics of a person by observing their living space. This has always been Gladwell's talent: taking just-under-the-radar topics and bringing them into the public's view through great journalism and storytelling.

Gladwell is also careful to examine the flipside of this phenomenon: the times when "thin slicing" misleads us or gives us the wrong results. For instance, he presents examples where the mind works based on biases that don't necessarily enter the realm of conscious thought, but are nevertheless there (age, race, height, and so on).

It's a great topic and Gladwell sets it up with some wonderful examples, but then the book begins to have problems. First, the book is a little too anecdotal. Anyone who has ever had a 200-level psych class knows that what looks like cause and effect may be accounted for by an independent variable that wasn't considered (e.g., concluding cancer rates are higher in some area of the country because of pollution, when in fact the area has higher smoking rates as well). Given this, I found that too often conclusions are made on basic handwaving, or that important aspects of studies are not mentioned. For instance, Gladwell describes a study were observers are asked to determine certain characteristics (such as truthfulness, consciensciousness, etc.) of students by observing their dorm rooms; but, never does he mention how exactly one would determine these characteristics of individuals in a scientific manner for comparison. Such omissions leave the reader a little less than convinced.

Nevertheless, even with this flaw the first third of the book supports the thesis and makes for the usual entertaining reading; but things derail from there. The examples start to seem more peripheral: a rogue commander beating the conventional forces in a war game exercise, an artist known as Kenna who apparently should have made it big but didn't (why this example is interesting I've yet to figure out), and some rehash about coke vs pepsi from one of his older articles.

By the end of the book the whole thing derails into examples that just don't seem appropriate for the topic. Sure a study of why Pepsi always does better than Coke in blind tastes tests is interesting (and you can read his article on this without buying the book on Gladwell's web site), but does a study of "sips" vs "whole-can drinking" — people prefer sweet for sips (Pepsi) — really say something about unconscious rapid cognition?

One of Gladwell's greatest strengths is in recognizing interesting things, and then bringing them into conscious awareness so we actually realize these things are happening (whether it be tipping points or rapid cognition). I think he's partly achieved that in this book, but it doesn't come together the way the Tipping Point does. One gets the idea that this topic may have been better handled in an article rather than a full blown book.
