Just about all of it fits.
INTPs lack follow-through and this can isolate their ideas from practical examination.Their notions become over-intellectualized and too abstract to be of practical benefit. With their sharp critical thinking and analytical abilities, INTPs tend to nit-pick, hair-split, and generally overdo simple issues. Their desire for accuracy and precision exacerbates any error they may perceive in themselves or in others — they are, in other words, highly self-critical. Wanting to be competent and know everything, their standards grow increasingly higher. When fear of failing becomes overly pronounced, INTPs are quick to feel unintelligent, slow, and powerless.
If stress continues, the INTP's mind seems to freeze and block out the vital information it has worked so hard to accumulate. Their creative juices stop flowing and they suffer from stage fright, writers block, and a general inhibition of their ingenious thinking and fluent language skills. Preoccupied with performance failure, INTPs become self-consciously distracted in anticipation of their failure. If the stress becomes too overwhelming, the fear of blanking out prevents them from taking risks in areas they desire to succeed in. Attempting to avoid incompetence, they fail to gain the expertise and mastery they so desperately need.
