In the public debate, problems due to excessive use of digital media are often explained with reference to neurological functions and addressed through calls for self-regulation. This digital backlash and the desire to disconnect from the digital environment can be understood as the latest expression of the perennial concern with adverse media effects. For decades, media and communication research has dealt with the question of what the media do to us, pointing out the complex entanglement of social, psychological, technological, political, cultural, and economic aspects that are part of the question. The difficulties involved in reaching any absolute conclusions have motivated critical media studies to formulate different research problems and thus risking missing the opportunity to make an important contribution in one of the more pressing public debates of our time. Drawing on Latour’s distinctions between “matters of facts” and “matters of concern”, in this chapter, we suggest that critical media and communication scholars ought to treat media effects as a matter of concern to remain a relevant actor in the public debate about problematic media use.
