If the future of democracy depends on young generations, whether and how they encounter news and politics is of paramount importance. Although political apathy and skepticism of traditional authorities are prevalent among young adults, social media influencers (SMIs) can and do capture their attention. Whether these often-frivolous yet engaging and trusted actors have enduring effects on the policy and political values, substantive and affective attitudes, and behaviors is an important open question. This online field experiment investigates the impact of encouraging Americans aged between 18 and 45 to expose themselves to five months of content produced by five SMIs of potential interest on Instagram, TikTok, or YouTube. We consider two variants of this treatment condition: (i) largely apolitical SMIs periodically producing progressive content as part of the Better Internet Initiative's fellows program; and (ii) political SMIs regularly producing news and political content from a progressive perspective. We further vary encouragement to follow assigned SMIs, cross-randomizing whether participants receive just recommendations, recommendations, and a small financial incentive to follow an account or recommendations and larger quiz-based incentives. The comparison between these treatment conditions, as well as with a pure control and several placebo groups, promises to illuminate how encouraged exposure to follow progressively-minded SMIs shapes the degree to which individuals engage with and are ultimately persuaded by this new mode of political information on social media.
