In social sciences, after having witnessed several “turns” (cognitive, linguistic, pragmatic, interactional), the authors observe the rise of the “qualitative turn”. Therefore quantitative research methods are not mainstream anymore. One effect of this rebalance between quality and quantity is the recent “resurgence” of mixed methods. However, a new challenge presses social research: creating new methods, which could combine both qualitative and quantitative approaches in a single instrument, squeezing the advantages of both in a single technique. With the benefit of lowering the costs and making more consistent the findings. Some “merged” methods already exist and QROM could be a visionary laboratory. The paper aims to discuss these issues.
