Abstract
The ´theorise-inquire´ technique is described, which supports the testing of both experts´ hunches and the quality of data sources. This technique is useful for the identification of data sources and data gaps by domain experts. We describe and illustrate the use of group contrasts, an analysis technique that allows an expert to explore and interpret repertory grids interactively to find significant contrasting relationships between attributes and test these against data sources.
