Positivists believe society could be improved through objective scientific knowledge, free from values of the researcher. Interpretivists, on the other hand, argue it is impossible for sociology to be value-free due to how research is subjective and influenced by values in all aspects. For instance, the sociologists own values influence the method they may use. Alternatively, Weber fits between the two and argues sociology cannot be free from values in the research process, but can be free from values when collecting data.
