The primary focus of philosophy of science in this century has been on theories and theoretical knowledge. Except for concern about whether phenomenal reports or reports of objects and events should count as data reports and whether data might be theory-laden and what consequences that might have for objectivity of science, data have been taken to be relatively unproblematic. But for scientists, questions about what are the data are often of paramount concern. Such controversies often overshadow controversies over theories or explanatory models. Scientists’ questions about data, moreover, do not turn on the philosophical questions just identified. Instead, for scientists, the overriding question is whether purported data is actually informative about the phenomenon in nature under investigation or whether it represents an artifact; that is, whether it was so much the product of the procedures used to generate the data that it could not be interpreted as providing information about the underlying phenomenon.
