In this post from 2012 I wrote that people may create fear in order to control other people. I explained that creating fear is an effective way of gaining people's attention, creating hyper-vigilance, suppressing their rationality, and legitimizing violence in order to fight the (supposed) threats and to enforce loyalty. People doing this set in motion a vicious cycle. In other words, a process of escalation seems to be inevitable. In order to keep their followers' fears sustained, and their rationality suppressed, they have to keep feeding them with new information about the (supposed) threat. By creating more fear they get more attention, suppress more people's rationality, legitimize greater violence and acquire greater control. These are the methods dictators use.
