广告中的免责声明似乎包含隐藏信息

Do those lightening fast disclaimers at the end of radio and television advertisements scare you away or simply seem like white noise required by regulatory agencies? According to Northwestern University and Wake Forest University research now online in the Journal of Consumer Research, fast disclaimers can give consumers the impression that an advertiser is trying to conceal¹（隐藏） information. However, trusted brands (versus trust-unknown or not-trusted brands) are immune to the adverse² effects of fast disclaimers. #

"Speak slowly or carry a trusted brand," summarizes Kenneth C. Herbst, assistant professor of marketing³ at Wake Forest University Schools of Business and co-author of the study. #

Eli J. Finkel, associate professor of psychology⁴ at Northwestern University and another co-author, offers concrete recommendations for marketers: "If you're promoting a brand consumers don't know or don't trust, use a slow disclaimer. Because consumers don't know whether they can trust you, you have to be careful to avoid seeming sneaky（鬼鬼祟祟的） . Fast disclaimers can seem sneaky.

#

"In contrast, if you're promoting a trusted brand, feel free to save time by using a fast disclaimer. Use your precious advertising⁵ seconds promoting your product rather than spending them on your disclaimer," he said. #

The study shows that when consumers either lack trustworthy information about an advertised brand or believe that the brand is not trustworthy, fast disclaimers undermine（危害，破坏） their purchase intention. In contrast, when consumers trust an advertised brand, they are unaffected by the disclaimer speed. #

These findings have practical implications for advertisers and policymakers. For example, according to Herbst, policies that regulate disclaimer content but not disclaimer speed could systematically⁶ favor some companies over others. #
