This is a psychometric test based on the work of Carl Jung and Isabel Myers-Briggs. Jung first coined the words introversion and extraversion ... one of the axes measured in the test. I have found it remarkably insightful, but then I am an INFP ... Introverted, Intuitive, Feeling, Perceiving ... only one percent of the population apparently.
