Abstract: Abstract The familiar state of tension associated with an incomplete collection or an unfinished jigsaw puzzle is predicted by Lewin’s (1926; 1935) field theory. This feeling evokes a drive to completion—a phenomenon we label the incompleteness effect—which is useful to marketers endeavoring to cross-sell products and services. In three studies using online product configurators, we find that consumers faced with visual representations of incomplete product category collections, such as an evening drinks menu or a puzzle with its pieces representing services, are significantly more likely to complete the collection or finish the puzzle by cross-purchasing from a greater number of product or service categories as compared to those using a conventional online shopping format. We identify theoretical mechanisms through which the incompleteness effect works and potential moderators for the effect. Findings suggest that managers offering products or services across several categories can increase cross-selling by eliciting people’s drive toward completion.
