From TFA: “Publishing his findings next week in The Journal of Ethics and Social Philosophy, University of Birmingham researcher Dr Merten Reglitz asserts that online fake news is symptomatic of a larger problem yet to be fully understood — namely, the enormous impact of the internet on democratic processes.”
This is a peer-reviewed paper, but I also have trouble calling it a study. The underlying article makes a philosophical argument but is not a typical research study (which I take to mean the collection of original empirical observations).
