Stereotyping others may be negatively related to one’s creativity, yet there is currently scant empirical evidence of a link between stereotyping and creativity; here, we explore this link in the marketing domain. In a field study, we introduced a novel intervention to disrupt marketeers’ dependency on stereotypes and boost creativity. The intervention decreased marketeers’ use of stereotypes when labeling consumer segmentation while enhancing the creativity of ideas. In a pair of online experiments, we asked participants to rate the stereotypicality and creativity of British advertisements and their purchase intention for the advertised product or service. We found a linear relationship between perceived stereotypicality and creativity. We also found a quadratic relationship between perceived stereotypicality and purchase intention, such that advertisements perceived as low and high stereotypicality induced higher purchase intention than the mediums. Finally, we discuss the psychological mechanisms that potentially link stereotyping and creativity and the implications for marketing.
