Abstract The recent visibility of polarization in online social media is an alarming phenomenon with plausible detriments to the health of our democratic process and discussion online. It prompted a new wave of interest in works that attempt to seek explanation to it via opinion modeling. In this paper, we offer one of such explanations by proposing a polarizing opinion model built on the idea of how news sharing online changes our opinion. By considering news propagation as the vehicle to polarization, we are able to see how the polarization of opinion intermingles with the polarized structure of news propagation found in numerous empirical works, something that has been missing from previous opinion models. The model polarized on exposure to polarized news of a reasonable degree but converges otherwise. We also performed systematic exploration of the model parameters and discuss how the behavior of the model mimics the behavior found in real social media.
