"Stories “change the course of insurgencies, frame negotiations, play a role in political radicalization, influence the methods and goals of violent social movements.”
[...] the Pentagon wants researchers to study how stories infiltrate social networks and alter our brain circuits. One of the stipulated research goals: to “explore the function narratives serve in the process of political radicalization and how they can influence a person or group’s choice of means (such as indiscriminant violence) to achieve political ends.”
Once scientists have perfected the science of how stories affect our neurochemistry, they will develop tools to “detect narrative influence.” These tools will enable “prevention of negative behavioral outcomes … and generation of positive behavioral outcomes, such as building trust.” In other words, the tools will be used to detect who’s been controlled by subversive ideologies, better allowing the military to drown out that message and win people onto their side."
