Statistically speaking,a quantity can be increased by any percentage but cannot be decreased by more than 00 percent.Once pollution has been reduced by 00 percent, for example, it ceases to exist,and no further reduction is possible.In defiance of this logic, however, advertisers sometimes refer toa 50 percent decrease in lost luggage or a new dental rinse that reduces plaque on teeth by over 300 percent. On reflection,it is possible to infer the intended meaning in these examples—presumably the rinse is three times as effective as some other tooth-cleaning procedure—but the ostensible claim is logically nonsensical,and the phrasing serves mostly to obscure the fact that the standard of comparison has not been made explicit.The latter phrase was unacceptable to '' percent of the Usage Panel.
從統計學上說，數量可以按任意比例增長但不能按超過百分之一百的比例減少。例如，一旦污染減少百分之百，它就會消失，也就不再會有任何進一步減少的可能了。然而，廣告商們時常忽視這種規律而提出行李丟失率下降了百分之一百五 或 一種新型爽口劑將牙病減少了百分之三百。 從觀眾的反應來說，不可能推斷這些例句想表達的意思——假定這種爽口劑比其它潔齒措施有效三倍——但這種表面的說法卻是不合邏輯的，並且短語的運用大大模糊了比較標準尚不清晰的事實。後一個短語是百分之六十六的用法小組成員不能接受的
