Believability and Doubtfulness: A Paradigmatic View of Qualitative Methods

Abstract

In the past, the focus of the literature concerning the comparison between quantitative and qualitative research has been on the relative warrants of the methodology of each approach. The aim of this essay is to reformulate this argument in terms of paradigmatic perspectives. In this respect, descriptions of the realist paradigm which determines quantitative methods and the constructivist paradigm which determines qualitative methods are laid out. It is shown that these paradigms are essentially incommensurate and direct comparisons are counter-productive. It is, in addition, suggested that the choice of one paradigm over the other is more a distinction between the relative values of research exactitude and research sufficiency and, as such, a question of believability.

Résumé

Par le passé, les textes comparant la recherche quantitative et la recherche qualitative mettaient l'accent sur la crédibilité relative de la méthodologie de chacune des approches. Le but de cet article est de resituer ce débat au niveau des perspectives paradigmatiques qui sous-tendent l'une et l'autre approche méthodologique. Le paradigme réaliste qui produit les méthodes quantitatives et le paradigme constructiviste qui produit les méthodes qualitatives sont décrits. L'auteur démontre que ces deux paradigmes sont essentiellement incommensurables et que toute comparaison directe est oiseuse. Enfin, l'auteur suggère que le choix d'un paradigme plutôt que l'autre est plus une distinction entre les valeurs relatives accordées à l'exactitude ou à la suffisance de la recherche et, comme tel, qu'il constitue une question de croyance.
