You've probably taken an online personality test before to figure out what combination of the four main personality types you are. There are 16 possible combinations. That isn't really a lot if you compare it to the number of people there are in the world. Every single person is boiled down to one of 16 personality types. Actually, it's more than just every person in the world. If you factor in fictional characters, you're adding in hundreds, if not thousands of other people who now also get to be assigned one of these personality types. 

Through questions crafted at digging deep into who people are, and asking the same question multiple times with different wording to see if the answer is the same, the Myers-Briggs personality test can almost positively determine your personality type. It's also become the authority on all things personality. The test was constructed by Katharine Cook-Briggs and her daughter, Isabel Briggs Myers, and is based on a theory by Carl Jung. Jung's theory was that people use the four psychological functions to experience the world, the four being sensation, intuition, feeling and thinking. Some of these are more dominant, while others are just contributing factors. Based on your own Myers-Briggs personality type, which Disney princess are you? Take this quiz to find out!
