berman argues that economics can provide a significant insight into the vulnerabilities of radical and terrorist organizations, although not only because of the common assumption that cutting their funding is key to their defeat. instead berman says that "terrorist organizations are terribly vulnerable to defection, the same way that firms are vulnerable to workers stealing trade secrets, or just shirking on the job." he further argues that the economics of religion can provide explanations for the way in which "radical religious communities organize mechanisms to control defection in order to successfully conduct mutual aid—which they tend to be quite effective at."
