All right, let me lay it out for you. My younger brother is an ISTP. He's really smart, technical, spends hours working on models of plastic cars and the like. He likes to walk on the wild side, and takes his time with tasks unless he feels the need to move faster. He'd also direct, tactless, and likes things to be expressed to him clearly the first time: No hidden double meanings and no mind reading.
Our mother is an ISTJ. She's fairly reasonable, always supportive, usually very calm and good at creating order among chaos. She'll listen to other ideas and allow people to take over if they're better equipped for the situation. She likes things to be in a just so and for it to all work out right the first time.
So this is where I need a little insight. My brother is budding into his twenties, and still has the teenager attitude of 'I know everything.' These two have been butting heads like crazy! My mother says something and it sets my brother off, or vice versa. They are both incredible stubborn and rather insensitive to the emotions they are stirring up in the other person. And once they start, there is little reasoning with them. They make my poor head hurt! Reason just doesn't seem to penetrate and there is nothing but hurt feelings and no one is ready to apologize to the other.
So what I'm asking for is a little help and insight to help my mother and brother bridge this communication gap. God knows I have tried to step in before it gets too heated and reason with the both of them. Sometimes it works, most times it doesn't.
So: Is there a communication barrier between ISTP and ISTJ? And if so, what are your suggestions?
