The Tipping Point

How Little Things Can Make a Big Difference
''The Tipping Point,'' by Malcolm Gladwell, is a lively, timely and engaging study of fads. Some of those he writes about fit snugly into the long tradition of crowd behavior: out-of-fashion Hush Puppies resurged into popularity in 1994 and '95; teenagers, despite repeated health warnings, continue to smoke and in the past few years have been doing so in increasing numbers; and in 1998 a book called ''Divine Secrets of the Ya-Ya Sisterhood'' reached a sales mark of two and a half million copies. Some of the other phenomena analyzed by Gladwell are a bit more unusual, including the decline in crime in New York City that began under Mayor Rudolph W. Giuliani. But all of them can be taken as examples of how unpredictable people can be when they find themselves in the throes of doing what everyone else is doing at the same time. - The New York Times
