We compared South Koreans with Australians in order to characterize cultural differences in attitudes and choices regarding risk, at both the individual and group levels. Our results showed that Australians, when assessed individually, consistently self-reported higher preference for risk than South Koreans, regardless of gender. The data revealed that South Koreans, regardless of gender composition, were willing to take greater risks when making decisions in group decision-making situations than when they were alone. This is a different pattern from that seen in the Australian sample, in which a risky shift was noted only among males. This difference was attributed to the influence of various cultural orientations (independent vs. interdependent relationship styles). This study also provides a discussion of the implications of these results in terms of cultural differences in attitudes and decisions regarding risk.
