The manifestation of Ni within an Ni-dom doesn't bear the greatest difficulty in efforts to find. You will undoubtedly come across an individual who often holds a concentrated, yet inattentive look. It makes them seem hazy at times like their mind is being tripped over and over... so in outward projection, it may look like a person who is concentrating on invisible surroundings that you yourself may have difficulty trying to apprehend simply because you are not experiencing within mind what they are. In communication, they may return what you say in different nodes of perception to give an alternate understanding of your deduction so as to play the trade of thoughts upon what is being reasoned. Opinions may often be given during communication of the thought, before the thought or in conclusive form of the thought depending on whether the Ni user has thought about the topic beforehand, or is processing it during conversation.
