For over three decades, an Ideological Surround Model (ISM) has pursued theoretical and methodological innovations designed to enhance the ‘truth’ and ‘objectivity’ of research into psychology and religion. The foundational argument of the ISM is that psychology as well as religion unavoidably operates within the limits of an ideological surround. Methodological theism, therefore, needs to supplement the methodological atheism that dominates the contemporary social sciences. Methodological theism should operationalize the meaningfulness of religious traditions and demonstrate empirically that the influences of ideology cannot be ignored. The ISM more generally suggests that contemporary social scientific rationalities need to be supplemented my more complex dialogical rationalities. Beliefs in secularization should also be supplemented by beliefs in trans-rationality.
