Recent events made me think about a particular chicken and egg problem: What comes first, political polarization or media polarization? And how much damage can media polarization do in a political system? The answer to the first question is probably: they’re mutually reinforcing, but the media wouldn’t be polarized if there wasn’t a polarized audience to begin with. The answer to the second question is less obvious, but relevant to all political systems where the media can tip the scales toward one side or the other, or possibly one extreme or the other.
It is a commonplace by now that the fragmented media landscape in many countries, much amplified by online media, allows members of the audience to get exposed only to political content that they actually agree with. There is so much out there, you never really need to listen to the other side. In the recent Presidential elections in the United States, this led to a curious phenomenon. The media on the right, and also voters on the right that mainly focused on those media, were convinced that their candidate would win and were genuinely surprised when he didn’t. The media on the left played the same trick on its audience. The media in the middle covered the election as if it was a close race, which it wasn’t, in order not to scare part of their audience away. Overall, one had to turn to foreign media to lose some of the bias.
