ISTJ's rule-following feels suffocating. "Because that's how it's done" drives you crazy.
INTP's theories seem impractical. They just think and don't act.
When you are INTP and they are ISTJ
When ‘why?’ meets ‘because that's how it's done’
A Logistician's respect for rules can feel suffocating to you. You ask ‘why do we have to do it this way?’ and they answer ‘because that's how it's done,’ and something in you quietly screams. ISTJs trust proven experience through Si and efficiency through Te, while you re-derive everything with Ti and imagine alternatives with Ne. Interestingly, their dominant Si is your tertiary function, so up close, an ISTJ can quietly shore up the shaky foundations of your daily life.

Working together
You bring fresh solutions and analysis; they bring systematic execution and quality control, and the output is both creative and dependable. Procedure is where you'll clash, so separate the rules that must be followed from the areas open to experimentation. Their careful reviews are the safety net that catches your mistakes.
In love
Each of you takes care of the other in your own way. ISTJs show love through action more than words, and since you're not fond of heavy displays either, it can feel comfortable. Differences in daily habits are the likeliest source of conflict, so divide chores and scheduling clearly.
As friends
A dependable friend who offers practical help when you're in a bind. Your topics may differ, but their constancy makes the friendship last.
