We argue that these problems account for some of the failures of the
research by Siegal et al. (in press) and Nobes et al. (2003) to find internal consistency in their
data. For example, the method of scoring responses as “correct” (scientific) or “incorrect”
forces grouping children into “scientific” or “flat” categories, but does not capture nuances
that could provide information about the synthetic models that children may have formed
