Well it seems an amazing research and thanks for letting us know about this provoking factor of human personality. With due respect i want to add one more point in the Results of Research.
Environment and Nurturing do matter a lot in one's behavior especially when it comes to harsh wording or Curse or even Anger.
It is astonishing to know that Women curse lesser than men ( It is a quite new thing for me )
Well In Islam It is said
Anger is Haram in Islam, it brings anxiety and pain
By the way as usual a very fruitful blog, Great Job
