I've been thinking about this for a while, and it puzzles me.
I've known three ISTPs, and quite a few INTPs and I am having trouble differentiating the two.
Could it be that the ISTPs I know happen to be innately ridiculously intelligent with more pronounced(?) or well developed Ti than some of the INTPs I know?
Regardless, what are the telltale signs that distinguish one from the other?
What makes this more puzzling for me is that, I know my being an ENFP as opposed to an ESFP makes kind of a huge difference.
So in this case, preferring or using Ne versus Se manifests in clearly distinctive ways, but for IXTPs such does not seem to be the case!!!
So, please, dear internet friends, share your thoughts/experiences/observations.
