Social medium Facebook and “big data” firm Cambridge Analytica have broken the news in March 2018 when their methods of political manipulation in the electoral campaign of Donald Trump in 2016 were made public. Why is it that the revelations on the Facebook – Cambridge Analytica affair appear morally so unacceptable?
I would like here to suggest a method, based on the well-established layer-based model of the human brain, to trace a moral distinction between tools used in political communication.
