"Who Am I?" questions are a series of questions (usually multiple-choice) that are designed to reveal something about the person who answers them. "Who Am I?" questions, unlike a knowledge quiz, have no right or wrong answers. Instead, the answers are compiled and analyzed to produce a response that supposedly indicates part of the respondent's personality and/or characteristics.
A large number of "Who Am I?" question personality quizzes are available online. These quizzes are increasingly popular on the Internet, having originally been derived from personality tests of psychologists using a set of question responses to determine something about a person's personality and/or characteristics. Most websites that host such "Who Am I?" personality quizzes often provide a link for displaying the respondent's results on a blog, allowing a convenient electronic means for people to share their personality quiz results. The questions are not necessarily scientific, so the results may not be accurate.
There are several different types of "Who Am I?" personality quizzes. There are quizzes that estimate compatibility, in which the quiz maker uses the quiz to indicate to respondents whether their personalities/characteristics are compatible with the quiz maker's. There are quizzes that reveal personality directly, often seen as quizzes with names like "What kind of person are you?" Finally, there are quizzes that attempt to categorize the respondent, such as those titled "What kind of job should you have?" Scientific or not, these quizzes are readily available and may reveal something to the respondent that was previously unknown.
