What is the main difference between INFP and INTP?

INFP leads with Introverted Feeling, which measures choices against private values and personal authenticity; INTP leads with Introverted Thinking, which builds a precise internal logic and tests it for consistency. That is the clearest fault line between them. In practice INFP leans on authenticity and creative expression, while INTP leans on analytical depth and pattern recognition. The only letter that changes is F to T, the axis of how they reach decisions, logic versus values.

How do I know whether I am INFP or INTP?

If you settle hard calls by what is logically sound, even when it costs you goodwill, you lean INTP (The Logician). If you weigh the human fallout first, INFP (The Mediator) fits. The honest test is which description you stopped nodding along to and started wincing at.

Why are INFP and INTP so often confused?

They both carry Extraverted Intuition and Introverted Sensing in their stack, so they can sound alike on the surface. Where they part is the driver: INFP leads with Introverted Feeling and INTP with Introverted Thinking, which pulls their attention in different directions over time.
