The concept of creating counter-narratives in order to push back against extremist recruitment and propaganda has become well established in recent years. In practice, however, it has proven difficult to curate this content in a systematic way, target it toward at risk audiences, and – most importantly – measure constructive impact on their behaviour. Over the past few years, the Institute for Strategic Dialogue (ISD) has developed research and pilot studies conducted with the Against Violent Extremism (AVE) network of former extremists and survivors of extremism that it manages. This research has been conducted in order to test and improve methodologies that help optimise the impact of counternarrative campaigns. This report outlines the key findings and results of three counter-narrative campaign pilot projects curated through the AVE network in coordination with Jigsaw and with additional in-kind assistance or financial support from Facebook and Twitter. Although some details and figures have been omitted for security purposes, the results of the study are presented in full.
