Previous research has demonstrated that when people have to choose a product for which they do not have a preference and can observe their partners’ choices in advance, they are more likely to imitate their partners’ choices when choosing privately, whereas they are likely to choose differently when they are with their partners. The present study extends this evidence by testing Japanese participants and examining individual differences in the need for uniqueness. Despite the Japanese cultural norm of interdependence, which is positively associated with conformity, less than half of the participants imitated their partners’ choices, whether they chose privately or publicly. Moreover, people with a high need for uniqueness tended to choose a different option when choosing in front of their partners. Implications for the consequences of social influence are discussed.

The dopamine D4 receptor gene (DRD4) is associated with novelty-seeking and risk-taking behaviors that have had an adaptive value in the history of human migration. It also plays a role in moderating the extent to which people adhere to cultural norms and practices. The aim of this study was to replicate previous findings about how DRD4 polymorphism interacts with cultural differences in social orientation, which revealed Westerners’ emphasis on independence and East Asians’ emphasis on interdependence. Testing Japanese and European Canadian undergraduates (n = 784), we succeeded in replicating these previous findings: the Canadian students were more independent, whereas the Japanese students were more interdependent. However, none of the interaction effects between culture and DRD4 were significant. Implications for candidate gene research investigating gene–environment and gene–culture interactions are discussed.

Scholars have explained political orientation and morality as a consequence of epistemic needs and empathic motivation. In this study, we replicate previous research on the influence of psychological states on moral foundations, system justification, and political orientation among Japanese participants. Consistent with previous findings, empathy is positively associated with care and fairness (called individualizing foundations) whereas epistemic needs to manage certainty (e.g., need for closure) are positively associated with ingroup loyalty, respect for authority, and purity (called binding foundations). Empathy and the need for closure indirectly affect political orientation and system justification through their influence on moral foundations. Contrary to previous findings, we find empathy to be positively associated with binding foundations whereas the need for closure is positively associated with individualizing foundations. We discuss the implications of these findings to show that moral foundations are a result of motivated social cognition.
