I think a good concept is that energy either goes in or out. I suppose it can be static, but it doesn’t seem to be in most people.
Extroverts, Cluster B types, sociopaths, manics, etc. all propel energy outwards, often dramatically so. They also project guilt and fear outwards, often transforming the fear into aggression because aggression is often “fear/guilt energy” turned outwards. Everybody thinks it is cool to be an extrovert, and we all think introverts are dangerous, but the truth is that extroverts are statistically vastly more dangerous than introverts.
And when introverts do act violently, that is when they are projecting their fear/guilt energy outwards for once. In addition, introverts are divided into angry introverts and passive on “non-angry” introverts.
I will admit that angry introverts can be dangerous. All of these introverted mass shooters running around are angry introverts, every single one, I can assure you. On the other hand, extroverts are statistically at least as violent as angry introverts and probably far more so. Go to a prison and look around. 95% of the offenders people and almost all of the violent offenders will be extroverts. Obviously people who not only propel all energy in general outwards but also project all aggression out at the world are capable of quite a bit of havoc.
