The personal data consumers share with companies on a daily basis often also involves other people. Yet prior research has focused almost exclusively on how consumers make decisions about their own data. In this research, we explore how consumers' social value orientation impacts their decisions regarding data about others. In contrast to the notion of proselfs as "selfish" decision-makers, across four studies we find that proselfs, compared to prosocials, are less likely to share data about others with third parties. We show that this effect arises because proselfs feel less ownership over data they hold about others than prosocials, which in turn reduces their willingness to share it. Overall, this work contributes to literature on social value orientation as well as privacy decision-making, and helps marketers and policy makers in designing interdependent privacy choice contexts.
To fight obesity and educate consumers on how the human body functions, health education and marketing materials often highlight the importance of adopting a cognitive approach to food. One strategy employed to promote this approach is to portray humans as machines. Five studies (and three replication and follow-up studies) using different human-as-machine stimuli (internal body composition, face, appearance, and physical movement) revealed divergent effects of human-as-machine representations. While these stimuli promoted healthier choices among consumers who were high in eating self-efficacy, they backfired among consumers who were low in eating self-efficacy (measured in Studies 1 and 3–5; manipulated in Study 2). This reversal happened because portraying humans as machines activated consumers’ expectation of adopting a cognitive, machine-like approach to food (Studies 3 and 4)—an expectation that was too difficult to meet for those with low (vs. high) eating self-efficacy. We tested a solution to accompany human-as-machine stimuli in the field (Study 5): Externally enhancing how easy and doable it was for consumers low in eating self-efficacy to meet the expectation of adopting a cognitive approach to food, which effectively attenuated the backfire effect on their lunch choices at a cafeteria.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
