Abstract
Digital media has transformed how citizens encounter politics, often through incidental exposure in ostensibly apolitical spaces. Prior research emphasizes content drift, where political information enters non-political spaces through algorithms or social networks. We theorize a different pathway—actor drift—where cultural figures embed political messages into their routine output, transforming audience perceptions. Analyzing millions of Instagram posts and comments from chef-influencers before and after the onset of the Israel–Hamas war, we show that identity-proximate chefs integrated political commentary into their culinary posts, which drew higher engagement but triggered disengagement from loyal followers. These dynamics capture a core tension: politicization extends the reach of cultural agents while eroding the parasocial trust that made them influential. Actor drift complicates theories of selective exposure, bypassing self-selection yet producing backlash that both disrupts and reinforces echo chambers.
