I think your perception of more variability in European faces than Chinese ones says more about where&amp;#x2F;how you grew up than about the actual variability. To someone who grew up in an Asian monoculture, without exposure to media with European faces, all Europeans would look alike too.</text><parent_chain><item><author>aab0</author><text>It could also reflect what is most distinguishable.
