This report showcases the detailed methods, results and lessons learned from three Behavioural Insights (BI) experiments that were carried out by UNDP with support from other UN entities, in Pakistan, Uzbekistan and Tajikistan from 2020-2021, aiming to use BI as a tool to strengthen the participation of women and youth into UNDP’s programming to prevent violent extremism. The report aims to provide practical insights for practitioners on how to design and carry out BI experiments for PVE by giving an insight into both the design process and the results of these three experiments. This knowledge product works as a supplement to UNDP’s practitioner guidance, “Applying Behavioural Science to Support the prevention of violent Extremism: Experiences and Lessons Learned”, which provides step-by-step guidance for practitioners to make use of behavioural sciences and experimentation to address violent extremism.
