If you were told that a particularly delicious-looking ice-cream cone(圆筒)contained dangerous chemicals, then told soon after that it was safe to eat after all, would you still choose it for dessert? So far, studies by behavioural economists have suggested that people have a hard time unlearning(忘记)what they have previously been told, even after being ordered to do so. But Uri Simonsohn, a professor of marketing at the University of Pennsylvania, has a forthcoming paper suggesting that some consumers, at least, are indeed capable of letting go of wrong information.
Mr. Simonsohn started by having to dismiss wrong information himself. In early 2007, shortly after he and his wife had bought a car seat for their first child, Consumer Reports magazine published a ranking of car seats according to safety. Unfortunately, the magazine had messed up its usually thorough testing procedure, with cars being crashed at much higher speeds than advertised. At a 35-mph side-impact crash, the structure of the car seat can make a difference; at 70 mph, the infant’s safety depends much more on the structure of the car. Two weeks later, Consumer Reports issued a retraction(收回声明): several car seat brands(including the Simonsohns’)were safer than the original rankings suggested. Mr. Simonsohn tracked online auctions of car seats after both the initial rankings and the retractions, to see how prices were affected. The car seats falsely charged with poor performance saw their prices drop, then rebound quickly. By contrast, one seat, which failed both Consumer Reports’ original and revised tests, continued to sell more cheaply after the retraction was issued. The car-seat buyers were apparently able to disregard the flawed rankings and pay attention to the correct information.
It helps, Mr. Simonsohn admits, that both the original rankings and the retraction were widely publicised: child-safety issues attract headlines. That the retraction was made swiftly may also have focussed consumers’ attention: a time lapse of months or more might have affected sales more profoundly.
