The idea that it is easy to predict how a given person would respond to a given provocation is in my view not terribly plausible, once the response-provoking behaviour gets beyond something banal like a simple greeting or extended hand in a typical social situation where both participants are familiar with the salient cultural norms.
If it was so easily predictable, then the real world would have fewer fights, less appeals-court litigation - because we would all know in advance how the judges would decide - and more successful diplomacy.
