# Conveyor Belt Model
**Entity class:** Contested radicalization model
**Maturity:** Developed

The **conveyor belt model** treats radicalization as a linear progression from grievance or nonviolent extremism toward terrorist violence. Critics argue that it collapses attitudes into behavior, overlooks divergent and reversible pathways, and generates false positives when used as a screening model.
