I was. I was comparing my B.S. model with yours. They both stack up about "that high."
Hmmm. THAT part is debatable. IMO, you tend to really be sloppy with nuances and lumping your apples with your oranges just because they all smell fruit

to you. Whatever -- that's your preference.
I actually linked this thread to the other forum where the person presented this idea, so she could see the discussion here. After seeing some of the posts here, I'm not really convinced on the ISFP/INTP conflict thing at all.
My roomie right now is also ISFP, and it's just reaffirming how I felt with my other ISFP friends -- that I get along far better with them than most other types DESPITE any "contrary" function use.
This might be a case where theory suggests one thing but other factors are involved that negate it.
I think the similarity of having a Ji/Pe function style is stronger than any differences between what those functions are... for this particular function I/E matchup at least (i.e., I think the Pe aspect, which colors the relationship heavily,
immensely reduces conflict). ISFP and INTP in general avoid personal conflict like the plague.
At worst, you'll get the INTP shooting off casual ideas, but they tend to get delivered through Ne in person (not the Ti), and the ISFP will appreciate them for what they are and just ignore the parts they don't care to entertain. And vice versa, the INTP might think the ISFP does some senseless things at times but enjoys their openness and easy-going nature.
