Comments on a paper by H. S. Kim, D. K. Sherman, and S. E. Taylor in regards to the consideration of culture, ethnicity, and national origin in the study of individual and group differences and social interactions. Erard claims that their attempt to infer from small, mostly college-student samples examined on a handful of variables in a few dozen studies is ambitious to a fault. The author claims that they have committed a complementary error in supposing that science can discern any distinctive traits or behaviors that accurately apply to a class of some 4 billion people of varying ethnicities and cultural backgrounds.
