Harry Potter Personality Quiz

Voldemort, from "Harry Potter",
uploaded by Mezza, originally by Gillian Rhett

This test is based on the principles of the Myers-Briggs Personality Typing system. I made up the questions myself but they're similar to (and influenced by) the questions you'd find on any other Myers-Briggs-based test.

Explanation of Results:

This type of personality test uses four indexes of personality and the combination of the four is your personality type. The first index relates to how you interact with other people and can be Extroverted (E), meaning you're more outgoing or Introverted (I), meaning you keep more to yourself. The second relates to how you make decisions; whether you're Intuitive (N), getting answers from within, or you rely on Sensing (S) information from your surroundings, using your five senses. The third relates to whether you're more emotional and Feeling (F) or rational and Thinking (T). The fourth relates to whether you prefer things to be organized, meaning you're Judging (J), or you prefer things to be more unbound, meaning you're Perceiving (P).
