It is a known issue with social science that culture will bias research focus and conclusions that align with where the researcher lives. A typical finding is that US researcher tend to find research data that demonstrate individualistic virtues, while places like China and Russia tend to find research data that demonstrate collectivism virtues. In general there are a few conclusion that should be drawn from that. One is that researchers tend to focus on research subjects that align with their own cultural biases, so while the data might be unbiased the choice of research subject is not. It is that naturally those researcher will have a harder time considering alternative explanation for a given set of data, even if that data itself is unbiased. The key is always to consider culture into context of research and understanding how it limits the ability of the researcher, especially when politicians take such conclusions and runs with it.
