Ti: Introverted Thinking manifests through a focus on how information works internally. It is predicated upon the desire to understand and a curiosity about how the world around them works internally. They do not focus on what the machine does, but on how it works. Ti users rely on their understanding of how the world works internally. This makes them curious and introverted due to the fact that their logic is pushed inward rather than outward. This does not mean that they do not try to innovate or change the world around them. It simply means that their work is a product of introverted curiosity, meaning that when they create, they do not necessarily interact with the external world, though they can interact with the physical, practical world or the abstract, theoretical one.

A Ti user who showcases the change Introverted Thinking can make without having to interact heavily with the external world is Albert Einstein, who revolutionized modern physics. With the help of Mileva Marić, his contributions were made during his “miracle year” and were deeply focused on understanding how things work. This understanding of internal mechanics, along with a usual field of focus, creates masters out of them, who tend to dominate in one particular field, whether physical or not. A notable example is Niccolò Paganini.
