I would like to know more about whether there are methods or techniques relating to the use of silence when dealing with openly aggressive or confrontational individuals.
In the past I have found myself in a few situations in ordinary social contexts and found using silence quite effective. I made sure I had enough personal space between the aggressor, was not reactive but showed confidence, when they moved forward I retreated mirroring their movements. Eventually they gave up hurling insults at essentially a mirror and walked away, because at that point I am guessing they realised how silly they looked and perhaps were concerned of the legal ramifications of being violent against someone who had clearly just been standing there listening to their tantrum for the past few minutes.
I am aware that the silent treatment is associated with passive aggressive behavior, but I am wondering if there are studies or methods that answer the question of whether silence is an effective method for dealing with openly aggressive/confrontational individuals?
