I have used this with my mom on a few occasions, I get loud for a single statement when she becomes what I consider stubborn in regards to a personal opinion that I will not backdown on, I honestly understand why she is that way, I attack a single statement and become loud, but not yelling, its an extremely firm voice, then back down in a way that is apparent. The second after I do this I will go back to a normal voice, continue the conversation in a normal manner. It basically kills her escalation. She does the same thing to my logic at times. I logically run around with reasons and she uses "felt" to put her foot down and I back down as I can tell this matters alot to her. While the possibility exists for this type of behaviour to escalate really bad, it actually escalates the worse within Ti/Fe types. Because the Fi/Te and the Ti/Fe have a huge difference in what matters it has never really escalated very far in the real world. ESTP and ISTP are really good at reading this within each other and we will back down. Its read as a "dont go down that road" and its respected whether its true or not.
Because I use this with values only and because Ti and Fi personal values differ its never been a problem. When its used for simply "morality" then it really complicates things because now you are bringing in values that dont even apply between the people in the argument, its turned into the "principle".
I have told my son, dont make me reach the point of having to yell. When I reach this point of yelling its for effect, its quick and if it doesnt work I go somewhere that is even worse for him and start taking things away. This point is when he starts crying, the yelling is a startle effect and a warning for somethinng worse. He defines whats worse, not me. When it is felt I will walk away as I dont want to emotionally lose control and regret what happens when people lose control.
