Preferred term

observation and theory-ladenness  

Definition

  • In the philosophy of science, observations are said to be “theory-laden” when they are affected by the theoretical presuppositions held by the investigator. The thesis of theory-ladenness is most strongly associated with the late 1950s and early 1960s work of N. R. Hanson, Thomas S. Kuhn, and Paul Feyerabend, and it was probably first put forth (at least implicitly) by the French physicist, historian, and philosopher Pierre Duhem about 50 years earlier.
