Abstract: Objectives In this systematic review and meta analysis we will collate and synthesize the evidence on media‐effects for radicalization, focusing on both cognitive and behavioral outcomes. The goal is to identify the relative magnitudes of the effects for different mediums, types of content, and elements of human‐media relationships. Methodology Random‐effects meta analysis will be used and the results will be rank‐ordered according to the size of the pooled estimates for the different factors. Meta‐regressions, moderator analysis, and sub‐group analyses will be used to investigate sources of heterogeneity. Implications The results of this review will provide a better understanding of the relative magnitude of the effects of media‐related factors. This information should help the development of more evidence‐based policies.
