The major problem in conducting interdisciplinary research projects is that in these projects two methodological model deploy against each other: quantitative method used in natural sciences on the one hand, and qualitative method used in human and social sciences on the other hand. As a result of such a problem, useful and constructive dialogue among the experts of different scientific fields seems to have reached a deadlock. The problem of ‘translatability’, too, has emerged out of the above problem. So, paying attention to language and its communicative criteria has come to focus. In this article, firstly, by considering the roots of such a problem and mentioning the theoretical foundations of the both methodological models, the deadlock of communication between scientific fields have been analyzed. Then, from the perspective of the theory of communicative action and universal pragmatics based on the critical theory, it is proposed that applying the method of ‘critical hermeneutics’ can break the deadlock. Not to mention that the methodological model of this article itself is based on Habermas’s communicative research method.
