First intelligence must be properly defined.INTJs, at least the ones I've known, are a bit more fatalistic. For example, I remember my INTJ and ENTJ got into this long debate about whether someone could improve their intelligence. INTJ said no, it's genetic. The ENTJ said yes, people just don't actually try to do it, but it's possible.
Then again, pessimism certainly doesn't always mean realism, but by common definition, there's my answer.
The INTJ is partially correct. Yes, it is genetic, but it also depends on how you are raised. You can learn ways to be more intelligent, but it is very difficult, and most naturally intelligent people have never been taught those ways, but still use them.the ability to comprehend; to understand and profit from experience

...and ENTJs are so focused on having their "standards" and making sure everyone does things their way that they lose focus of what's really practical. Seriously, you can make any type seem unrealistic if you only focus on their weaknesses (but I don't think that's really a weakness of an INTP, probably more a result of them using Si because it's the only thing they have that's similar to anything you have). What about the ENTP's ability to infer things from the slightest detail? Or the INTP's ability to think outside the box when forming plans?Not ENTP because reality is boring and not INTP because they see the details but seem to be missing the forest (or the continent) entirely. If it's an enclosed case of determined variables thing, INTP might work.
