Abstract
Aim
The article considers methodological problems of working with register data and shows how deficiencies in a quantitative dataset may constitute a tool for discovery if data shortcomings are used as input in a qualitative investigation of data genealogy.
Data
Based on a specific research case example the article demonstrates how qualitative moments are intrinsically embedded both in quantitative datasets and in the statistical processing.
Conclusions
It is argued that statistical analyses of datasets cannot be made without considerations of institutional organisation and perceptions of persons implied in the production of data. Lastly it is suggested that prison-based drug misuse treatment research currently needs to face the paradoxical challenge of excessive statistical programmatic power, which has encouraged formulations of ‘causalist’ research questions. It is further suggested that a reorientation towards theoretical explanation as an addition to the statistical demonstration of factor associations is important if quantitative studies are to further open the black box of treatment.
