This article discusses the nature of and an approach to address investigator bias in research that originates from the theory-ladenness of observation. Theory-ladenness essentially holds that everything one observes or perceives is influenced by and interpreted through one’s existing beliefs, values, assumptions and expectations. This article explainshow the philosopher Ludwig Wittgenstein’s exposition of belief system – what he calls ‘world-picture’– illuminates our understanding of investigator bias and theory-ladenness by elucidating the organisation, inculcation and revision of beliefs. It is further proposed that comparativists confront the challenge of investigator bias by critically reflecting on their world-picture, the impact of their world-picture on their theoretical commitment and research process, and the evaluation and revision of their theory through the interaction between theory and data.  \nIntroduction  \nA variety of conceptual tools and methodologies has been adopted by scholars in the field of Comparative and International Education (CIE) . To date, there is a strong tradition within the CIE field of utilising and integrating diverse disciplines, such as science (e.g., positivism), sociology (e.g. externalisation, loose coupling) and even medicine (e.g. the epidemiological model of global dissemination) (Epstein, 2008; Steiner-Khamsi, 2014) . However, relatively less attention has been devoted to philosophy as a source of or inspiration for innovative methods in the CIE field. Drawing upon philosophical writings, this article examines the problem of investigator bias that originates from the theory-ladenness of observation, and proposes an approach to address this problem in research. Besides referring to the literature in the philosophy of science, this essay turns to the works of the philosopher Ludwig Wittgenstein to elucidate the essential qualities of belief system and its implications for theory-ladenness and investigator bias.  \nThe paper begins by highlighting the challenge of investigator bias in research and its connection to theory-ladenness. This is followed by an exposition of Wittgenstein’s views on belief system and a suggested approach for researchers to avoid or minimise the effect of investigator bias. The example of research on China will be given as an illustrative case study.  \nInvestigator Bias and Theory-Ladenness in Cross-Cultural Research  \nA perennial problem faced by researchers, including comparativists, is the effect of investigator bias in research. In simple terms, investigator bias refers to “errors in study design, implementation, or analysis by the investigator”(Aparassu & Bentley, 2015, p. 51) . O’Neil and Nicklas (2014) point out that conflicts of interest such as “funding sources, selection of study participants, hiring of personnel, purchase of equipment, choice of analyses, and interpretation of the data” may occur when a personal consideration compromises or appears to comprise the integrity of the study in any way  \n© 2015, Current Issues in Comparative Education, Teachers College, Columbia University.

For example, a biased researcher might interpret study results in ways that favor the funding agency (ibid) . The focus of this essay is the effect of investigator bias that originates from the theory-ladenness of observation.  \nTheory-ladenness affects all researchers and applies to all disciplines.
