 Irvine (2013, forthcoming) has argued that the methodological problems in this area are so severe that the term “consciousness” should be eliminated from scientific discourse as impossible to effectively operationalize or measure. Feest (2014) and Timmermans and Cleeremans (2015) similarly highlight the substantial methodological challenges using introspective reports in the science of consciousness, though without being quite as pessimistic as Irvine.
