PurposeFocusing on firm-initiated brand communities, the purpose of this paper is to systematically examine the influence of brand community rejection on consumer evaluations and document the underlying mechanism involved.Design/methodology/approachFour empirical studies were conducted to test the proposed hypotheses. Using a similar 2 × 2 study design, different subject samples and different product categories, Studies 1-3 investigated whether a brand community rejection strategy impacted strong brands differently than weak brands. Furthermore, Study 3 measured reactance as a moderator to explore the underlying process of the impact of a brand community rejection strategy on brand evaluations for different types of brands (i.e. strong vs weak). Study 4 used a 2 × 2 × 2 between-subjects design to examine whether justification would eliminate the negative impact of brand community rejection on subsequent brand evaluations for a weak brand.FindingsAcross the four studies, the findings consistently suggest that rejection from firm-initiated brand communities harms weak brands but not strong brands. In addition, by incorporating psychological reactance as a moderator of this effect, the authors uncover the process underlying the interaction between brand community rejection and brand strength. Furthermore, the paper examines the reasons that justify rejection to find a solution that eliminates the negative impact of brand community rejection on brand evaluations for weak brands.Originality/valueTo the best of the authors’ knowledge, this research provides the first investigation of the effects of a brand community rejection strategy for different brands. The findings could advance the social exclusion literature and shed new light on brand community research.
