Malcolm Gladwell reviews Free by Chris Anderson: Books: The New Yorker
Anderson’s second point is that when prices hit zero extraordinary things happen. Anderson describes an experiment conducted by the M.I.T. behavioral economist Dan Ariely, the author of “Predictably Irrational.” Ariely offered a group of subjects a choice between two kinds of chocolate—Hershey’s Kisses, for one cent, and Lindt truffles, for fifteen cents. Three-quarters of the subjects chose the truffles. Then he redid the experiment, reducing the price of both chocolates by one cent. The Kisses were now free. What happened? The order of preference was reversed. Sixty-nine per cent of the subjects chose the Kisses. The price difference between the two chocolates was exactly the same, but that magic word “free” has the power to create a consumer stampede. Amazon has had the same experience with its offer of free shipping for orders over twenty-five dollars. The idea is to induce you to buy a second book, if your first book comes in at less than the twenty-five-dollar threshold. And that’s exactly what it does. In France, however, the offer was mistakenly set at the equivalent of twenty cents—and consumers didn’t buy the second book. “From the consumer’s perspective, there is a huge difference between cheap and free,” Anderson writes. “Give a product away, and it can go viral. Charge a single cent for it and you’re in an entirely different business. . . . The truth is that zero is one market and any other price is another.”
