Abstract: | This study aims to investigate negative consumer‐brand relationships by developing a “Brand Hate” concept. A hierarchical Brand Hate model is theoretically discussed in light of the psychology and consumer behavior literatures. In Study‐I the Brand Hate concept was tested with two different types of consumer brand haters, true haters, and regular haters. The study found that in the study's proposed multidimensional Brand Hate hierarchy true haters display “Boiling Brand Hate” while regular haters reveal “Seething Brand Hate.” Two additional studies were developed to examine the relationship between consumer personality traits and Brand Hate, exploring which types of consumers are more prone to feel hatred toward targeted brands. Study‐II's findings revealed a relationship between consumers who are high in personality traits of “conscientiousness” and those who Brand Hate. Study‐III's findings indicated that “self‐confident” and “competitive” consumers might also be more prone to feel hatred toward those brands that perform poorly and unethically. |
