(Re)Design to Mitigate Political Polarization: Reflecting Habermas' ideal communication space in the United States of America and Finland

Social Media platforms are increasingly being used for political activities and communication, and research suggests that social media design and use is contributing to the polarization of the public sphere. This study draws on Habermas' ideals concerning deliberative democracy to explore if novel interface designs that diversify information sources through content recommendation, can decrease polarization. Through a design-probe interview approach and insights generated from 19 political and citizen experts in Finland and the United States, we found that our deliberative design can lead to depolarization, while creating additional complexity through which users question content and information. We discuss the need to move beyond naive content recommendation, and user interface level changes, in order to work towards a depolarized public sphere.
