Welcome to Twins: An Interactive Personality Test! This site lets any two people, regardless if you're actually twins, compare your personality and behaviors on a number of criteria.
This test utilizes well accepted psychology instruments and gives you instant, free, and anonymous feedback on some aspects of your personality and behaviors. You'll learn a bit about your personality, and optionally, a bit about some of your past behaviors and experiences.
You don't need a twin or second person to fill our survey out: you'll still get meaningful results in the preliminary results. Since the data from this site is being used for twin research, we would greatly appreciate if you'll spread the word about this site to friends who have twins. And if you are yourself a twin, welcome and thank you!
