Unlike quick "fun" personality quizzes, this extension uses the IPIP Big-Five Factor Markers — a well-established, publicly available 50-item instrument developed for personality research. Each trait is measured using both positively and negatively worded statements to keep results reliable and less prone to simple "always agree" bias.
