Chinese participants were found less likely to social loaf when working in groups than did North Americans. This result was attributed mainly to the collectivism and individualism characterizing Chinese and North Americans, respectively. However, this explanation does not address how Chinese people's social loafing tendency may vary across situations. If Chinese participants are concerned about their relations with coworkers, they should be more likely to conform to the performance level of their coworkers. This prediction is in opposition to effort dispensability, which is usually found among North Americans, whereby individuals adjust their effort in reverse to that of their coworkers. Consistent with our prediction, findings from three studies revealed that Chinese participants tended to conform to the performance level of their coworkers when their performance is made public (vs kept anonymous) and when they have high (vs low) relational concerns. These findings have implications for unpacking nuanced cultural influences on behaviours.
