This article investigates the effects of consumer decision‐making styles on consumer confusion and harm. While consumer confusion has been well documented in the literature, this investigation attempts to bridge our understanding on its relationship with consumer decision‐making styles. Empirical data was collected from a field survey where 400 consumers selected at 20 supermarkets in Mauritius were asked to respond to a questionnaire measuring three variables under study: consumer confusion, consumer decision‐making styles, and situational factors. Findings from the MANOVA parametric test showed that there is a significant difference between consumer decision‐making styles and consumer confusion. Even when covariate situational factors were controlled through the parametric test MANCOVA, results still showed a significant difference between consumer decision‐making styles and consumer confusion. More specifically, ANCOVA tests showed that the findings were specifically significant for three types of confusion: product confusion, packaging confusion, and product complexity. The study tends to confirm that a consumer's style of decision making does impact on consumer confusion.
