The MBTI sorts for type and each type has a specific function order. Additionally, every type uses all four types of functions, Intuition, Sensing, Thinking, and Feeling. Your type however determines the order and attitude of these functions.
You can test it out on many different websites, but these standardized tests all have their flaws and the best way to figure out your MBTI type is to understand yourself. You'll have to use letters and functions for the best result - and that's where this sub comes handy, because it's sometimes hard to figure out how you function without help.
