Fighting Violent Extremism With Narrative Intervention: Evidence From a Field Experiment in West Africa
在布基纳法索132个村庄开展随机对照试验，发现广播剧形式的叙事干预能减少暴力正当化、增加与警方合作意愿，但对警方信任无显著影响。
Violent extremism is one of the major challenges of our time. A cluster-randomized controlled trial with two arms (treatment vs. control) conducted in 132 villages in the Sahel region of Burkina Faso ( N = 2,904 participants) examined whether a narrative intervention in the format of a radio drama can shift behavioral intentions, beliefs, and attitudes in contexts of violent extremism. Individuals in intervention villages participated in weekly listening sessions to the radio drama (6 months’ content) over 12 weeks. Compared with the control condition, the narrative intervention reduced justification of violence, increased behavioral intentions to collaborate with the police, and increased prioritization of addressing violent extremism. The intervention did not influence beliefs about or attitudes toward the police (e.g., trust, fairness) or beliefs about police–community collaboration. Content analysis of the narrative intervention and participants’ reception and discussion of the intervention provide insights on the processes driving the intervention’s influence.
