A comparative NLP analysis was carried out across fifteen manifestos on a scale from violent terrorist to non-violent politically moderate. We used a dictionary approach to measure the statistical significance of narratives previously identified in terrorism literature in predicting violence. The NLP analysis confirmed our research hypothesis, finding that the linguistic markers of identity fusion (an extreme form of group alignment whereby personal and group identities become functionally equivalent), dehumanising language towards the out-group and violence condoning norms were statistically significantly higher in manifestos of authors who engaged in acts of violent extremism.
