Lost in a Maze? On the Philosophical Problems With Differential and Individual-Level Susceptibility in Research on Media Effects

This paper provides a philosophical discussion of moderators and person-specific differences (referred to as "hedges") in research on media effects. It is shown that while, historically, the reliance on hedges has been regarded as a sign of theoretical sophistication (the "hedges-as-progress-perspective"), it has left the field behind in a maze of epistemological problems. The paper therefore urges to reinterpret the role of hedges as a sign of theoretical resilience instead of sophistication (the "hedges-as-protection-perspective"). This shift is shown to have substantive implications for how one describes and evaluates media effects research-not just its history, but also its current state and its ambitions going into the future.
