The eight functions
Ti: Introverted Thinking
"Does it make sense?"
Ti builds an inner model of how things work, and checks every claim against it.
What it does
Introverted Thinking judges by inner logic. It takes ideas apart down to their principles, defines terms exactly, and keeps only what is consistent. Jung described it as thinking that starts from the person and comes back to the person: it cares more about deepening an idea than about collecting more facts.
It is the function of understanding for its own sake. It does not ask whether an idea is popular or useful, only whether it holds together.

The Ti and Fe axis
Ti's opposite is Fe. Ti asks what is true for me; Fe asks what is good for us. A strong Ti grows by noticing how its truths land on people; a strong Fe by daring a truth that might disturb the peace.
BeebeTi in each of the eight seats
The same function feels very different depending on where it sits in a type. Your own seat is marked.Pick your type at the top to see yours.
In the light: the ego
Logic is your playground. Puzzles, exact words and figuring out how things work are a delight.
Being logically right is your soft spot. Under stress you can turn coldly critical and nitpicky.
In the shadow
Opposing PersonalityENTJ ESTJYou
Picky logic can put you on the defensive. When pushed, you argue every detail to prove the other person wrong, or refuse any reasoning but your own. Made conscious, it helps you check your ideas for consistency.
When you feel attacked, you become a cold critic: you take other people's arguments apart and call them stupid. Accepted, it becomes clear, fair judgment.
Your deepest fear here is being exposed as foolish or wrong. When everything falls apart, it turns into a cutting logic that tears people down, yourself included. Met and accepted, it gives you a rare clarity of mind.
