I think you are confusing Ti and Ni, so to help you decide I am going to explain, or rather, I give you even more headaches, about what Te, Ni, Ti and of course Fi actually are.
Te is the dynamic perception (how, where and why something "moves") of an object (to simplify it let's say that the object is anything, for example, it can be a table, a person, a theoretical concept, etc.), that means Te perceives, conceives and organizes the how, when, and the goal of the movement of things related to matter and logic, that is why it is alternatively called logic of actions or algorithmic logic.
Ti perceives the fields (let's say that the fields are a system of relations between objects, and not the objects themselves) in a static way (which does not change), as regards to matter and logic, that is, Ti perceives, conceives and organizes the logical connections between things, sometimes generating theories and systems of logical interrelations (for example, socionics as a system is highly Ti) which is something that sounds quite like what you say that bothers you.
Ni is it the dynamic perception of fields related to a process or time, that is, Ni does accumulate interrelationships between patterns to determine the most likely result of a given process over time.
And, finally, Fi statically perceives the fields related to energy, and generally emotions, that means, a system that organizes and percieves a variety of emotional ties between things or people (He likes this kind of thing, I like this person, I hate that person or concept, etc.).
