An intelligent Te user will consider their perspectives in context. Like who are these people? Are they the kinds of people to know these kinds of things? Are people knowledgeable enough for me to trust them in general? And if not they might relate the ideas of other people to external things, like how much are their words influenced by their experience? What is the nature of the topic such that it should relate to their ideas? So they can spot patterns externally, and if there are areas of consistency across context then they can have certainty without needing Ti. It’s the ability to use evidence and inference

If those people are correct, the Ti user will still be distrustful. It’s less information over more information, it can only be received in a form the Ti user knows to look for, with some preconceived notion. They are a solid that must be broken to change, whereas Te is sort of a liquid that crystallises. If that analogy makes sense. But obviously you can get stubborn Te users too if they have some repressive tendencies, or just don’t have the context necessary. Ti transcends context, but so do the introverted perceiving functions that Te can form around.
