Pretty close to sane for once
A rare semi-sane output of "social" "science". The article by Waldrop et al discusses partisan polarization from a strictly objective viewpoint, without even ONCE displaying the views and purposes of the researchers. Every observation is accurate, and the authors simply STOP after making the observations.
99% of articles along this line start out objective and then end up screeching EXTERMINATE EXTERMINATE EXTERMINATE ALL UNTERMENSCHEN.
They come close to screeching at one point:
Conversely, though, the same lesson—avoid loud and dogmatic virtue-signaling—could be worth remembering for people trying to promulgate truthful information about, say, vaccines or climate change.
We know what you think "truth" is, but at least you managed to avoid saying it. Practicing what you preach instead of screeching what you preach.
In fact their strict objectivity may have missed an important cause.
They’re starting to understand why some of the most intense social polarization seems to be driven by relatively small cadres of highly politicized individuals who mainly talk to each other.
Maybe you should ask who these small cadres are working for. I bet you'd find
BOTH sides are working for Deepstate.
Putting it another way, you should ask the metaquestion. Beyond all the fake noisy "sides" there are two real sides. One side wants total and eternal WAR AND CHAOS. The other side wants stability and calm. All the money and power is on the WAR side. See Machiavelli.
