Fear, uncertainty and doubt - Wikipedia, the free encyclopedia
“ Fear, uncertainty, and doubt (FUD) is a tactic of rhetoric and fallacy used in sales, marketing, public relations,[1][2] politics and propaganda. FUD is generally a strategic attempt to influence public perception by disseminating negative and dubious/false information designed to undermine the credibility of their beliefs. An individual firm, for example, might use FUD to invite unfavorable opinions and speculation about a competitor’s product; to increase the general estimation of switching costs among current customers; or to maintain leverage over a current business partner who could potentially become a rival. ”
