Overall, this pairing may face challenges due to their different ways of experiencing the world.

INFJ’s and ISTJ’s are significantly different, even though they are both I(N)troverted and (J)udging personalities who prefer to spend time alone and stick to a plan. INFJ's are forward-thinking, compassionate, and creative, whereas ISTJ’s think logically and concentrate on the present.

Historically, this is deemed an awful match because their cognitive functions are in the opposite order – which often leads to poor communication and misunderstandings. 

Great maturity and a healthy respect for the other’s differences are paramount for this to work.

ISTJs and INFJs can understand each other's desire for order and purpose, but they also have differences that require understanding and compromise.

ISTJs and INFJs share a desire to contribute to society and uphold values and traditions. Yet, their different cognitive functions can lead to different perspectives and approaches to life.

ISTJs are grounded in practical reality, prioritizing facts, details, and practical solutions, while INFJs are future-oriented visionaries, focusing on possibilities, meanings, and insights about human nature. These differences can both enrich their relationship and become sources of misunderstandings.

Despite these differences, ISTJs and INFJs can form a strong bond based on mutual respect, shared values, and common goals. They can support and learn from each other, with the ISTJ providing practicality and consistency and the INFJ offering insight and empathy.
