MDes: an upgrade?

If well there is always the question of why do we follow certain studies of different levels (technical, professional, master), in design is a particularly relevant issue, for the creative essence of the discipline. In a bachelor level, design students are taught to be designers and, somehow, they learn to think, speak, make as designers. This comes with a body of knowledge around materials, shape, process, history and human factors, among other fields. Now, when a designer decides to follow a master program, can it be considered just an upgrade? a deepening of certain abilities or skills? a specialization? In my opinion, no. In general, master programs should help the student to reflect in their own practice in a critical way, which implies the unlearning of what was learnt in their bachelor studies. If Anthony Dunne and Fiona Raby defined critical design as opposing to affirmative design (which reinforces the status quo), we could say that self-critical design is design that opposes the status quo… of design. Maybe this is what a master program for a designer can build: a self-critical practitioner.
