This is an interactive personality quiz that will determine your similarity with a long list of fictional characters.
...here is an attempt at a slightly more scientific, but still silly, "Which Character Are You?" test.
This test was created by getting volunteers to rate the perceived personality of a variety of characters (currently 1,600). A user's self ratings are compared against these profiles and the closest match is found. The documentation on how this quiz works can be found here. There is also a peer report version, which addresses the bias problems of self-reports, and a version for couples.
