If suicide attackers are fused to the group through shared experiences then maybe we can influence the process of fusion as it occurs or develop ways of modifying the memories on which fusion depends. But our research with twins and other family members has shown that fusion is also driven by perceptions of shared biology. Indeed, the most common group for people to fuse with is close family members. CSSC researchers are therefore exploring interventions as simple as having radicalized individuals talk to each other about their experiences in a way that is structured and supported by their families. We are gathering evidence that mothers in particular have an especially important but currently under-appreciated role to play in such interventions.
