New #OpenAccess publication on the #Effects of Algorithmic #NewsRecommendation Systems (NRS): https://doi.org/10.1177/08944393221149290

In an experiment, we test whether exposure to #News selected by content-based #NRS leads to more #Polarization than exposure to random news items.

Results:
- Only very limited overall effects on polarization (= not supporting the #FilterBubble notion)
- But: If #Algorithm overemphasizes articles with #NegativeSentiment, #AffectivePolarization rises alongside reading time
