PROTOCOL: What are the effects of different elements of media on radicalization outcomes? A systematic review.

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.
