While analysis of publicly stated goals and objectives of cults may provide hints about their behavior and intentions, it is just as likely to be uninformed or, at worst, misleading. Much more valuable is a thorough examination of the cult leader, his position of power over his followers, and an awareness of the responding behavior and activity of the cult. Sudden changes in activity – for example, less time spent on "Bible study" and more time spent on "physical training" – indicate that the cult may be preparing for some type of action.
