And here - this is long but relevant. You could also check out the references for more material.
From the article above:
>Given these findings, how is it that people often persist in believing that people from different countries hold different values? Some factors are likely to be motivational: abundant evidence points to the roles of realistic group conflict (Bobo, 1983), social identification (Tajfel and Turner, 1986), symbolic racism (Kinder and Sears, 1981), and various biases (e.g., symbolic self-completion, Gollwitzer et al., 1982, or system justification, Jost and Banaji, 1994) that can lead us to feel that our own group is superior to other groups in numerous characteristics, including values. Other factors are cognitive: social learning (Bandura et al., 1961) and stereotyping processes (e.g., illusory correlation, Hamilton and Rose, 1980) may lead us to encode other groups’ characteristics in ways that magnify the differences between groups. More relevant to the present research, however, is the nature of the values concept itself. Specifically, as abstract ideals, values subsume a wide range of behaviors as exemplars of the concepts. People may perceive differences between social groups because of the differences between groups in the specific behaviors that are seen as exemplars of different values, even if other behaviors that are exemplars of the values do not differ. Thus, by thinking about groups in terms of concrete instances, differences may be stronger than similarities.
>In other words, people in different social groups may endorse the same values but associate different behaviors with them (Maio, 2010).
