Ti just looks for a general direction that it can work with, while Te strives for objective knowledge. for example, Ti might observe the pattern that ethical men and logical women are more likely to be homosexual. just patterns and the generalalisations. Te on the other hand might disregard this claim unless there have been studies done and data has been collected. same with socionics, which is a field that is dominated by Ti valuing types, while the scientific community is mostly dominated by Te valuing types. they disregard speculative theories, and Ti doesn't care to objectively prove it.
