I heard people who use their people's weakest function as their strongest point have a hard time with each other. Ti and Ne finds faults in everything why everything is absurd. Fe and Si likes to make choices based on popularity and likes to preserve traditions just the way is it. I can think of controversial topics on why these two types have trouble with each other such as religion. INTP may want to get rid of religion motive by their first two function while ESFJ's would preserve it. I'd have to side with ESFJ's on this one wanting to preserve religion just because most people like it. However, this example is extreme though not a representative of why all ESFJ's and INTP's might not get a long.
