RT Journal Article SR Electronic T1 Advertising Empirical Generalizations: Implications for Research and Action JF Journal of Advertising Research JO J Advert Res FD WARC SP 246 OP 252 DO 10.2501/S0021849909090369 VO 49 IS 2 A1 Yoram (Jerry) Wind A1 Byron Sharp YR 2009 UL http://www.journalofadvertisingresearch.com/content/49/2/246.abstract AB A special conference on empirical generalizations (EGs) in advertising led to this special issue of the Journal of Advertising Research. It also generated a representative selection of 23 EGs that give a sense of how strong our scientific knowledge is about advertising, and where the gaps lie. While real advances in knowledge have been achieved, the list highlights significant knowledge gaps, particularly concerning advertising in the new fragmented interactive-media world. We surveyed advertising thought leaders on which of these empirical laws they felt were most important and most certain. Many of our empirical laws suffer from inadequate knowledge concerning the conditions over which they do and do not generalize.
