This chapter addresses two challenges in interviewing: how to grasp tacit and taken for granted practices and representations, and how to get data on accounts or practices that are not part of the official discourse on the phenomenon under study. Professional practices and life more generally are full of routinised practices and tacit knowledge that the people engaging in them are hardly aware of doing. Yet, such practices may be very defining for a profession, or be a key to understanding power-relations. However, how can we as researchers grasp them? Another challenge for researchers is the way people tend to say one thing and do something else. Getting behind established self-presentations and grasping people’s practices is a challenge, in particular through interviews. However, although we surely should try to diversify the methods we use, interviews are often the only or the best approach in a given situation. Does that mean that we should give up on getting data on practices? This chapter discusses the relationship between data on discourse (or accounts, representations, norms) and data on practice, and defines this relationship in terms of a continuum rather than a dichotomy. Finally, it discusses specific tools that one can use in interviews to get data on practice, and data on representations and norms closer to practice.
