Discusses Lawrence A. Hirschfeld's (1995) experiments, which Hirschfeld claims demonstrate that preschoolers use a biologically grounded theory in reasoning about race. Argues that the methods used cannot address the issue and therefore, the results do not support Hirschfeld's claims. Maintains that the experiments fail to demonstrate that 4- and 5-year olds' reasoning about race is qualitatively different from reasoning about non-biological properties. (Author/KB)
