Purpose Social media (SM) platforms have become major sources for generating, sharing and gathering political and election news. Although there appears to be an assumption that reliance on SM for political news consumption will continue to gain in popularity, there are reasons to believe that many Americans are retreating from using SM for political news. The purpose of this study is to examine if Americans are reducing reliance on SM for political news and to analyze why retreat may be happening. (...) Design/methodology/approach Using longitudinal panel data from Pew’s American Trends Panel study, the authors tracked 993 respondents from February of 2016 to November of 2019 to monitor their reliance on SM for political news leading up to the 2020 US presidential election. Findings The results of this study indicate that a sizeable percentage of people (about a third) are retreating from SM platforms for political news consumption and some are abandoning it altogether – people we refer to as new SM “nones.” The authors find that retreat from SM is associated with increased distrust of the information found on the platforms. Concerns about fake news, incivility on SM and information overload were unrelated to retreat from use of SM for political news consumption. Originality/value The findings of this study are novel and suggest that reliance on SM for political news by the public may have waxed, seen its zenith and may now be waning largely because of distrust in the information found on SM platforms.
