The origins of this list have been referred to as "The Mother of All Character Questionnaires."
This comprehensive inventory of thought-starting questions is useful for building your own character questionnaire. The survey has been used by actors, role-players, reenactors (both revolutionary and medieval) and writers to provide fuel for the creative process of inventing a whole persona. Fictional characters need a level of depth sufficient to be complex and believable. In today's world, the nuances of personality and interplay must reflect the depth of interaction found in real life. Whether your characters are human or not, your readers most certainly are!
Character survey questions cover different genres and types of details, so feel free to exclude or modify to suit your specific needs. The questions are divided into broad categories, and similar questions are grouped together. For brevity, assume that just about any of the questions can be expanded with a simple "Why", "How", and so on.
To provide full credit it where it is do, you should know that this list was originally adapted and expanded from a tool in Johnn Four's newsletter over at RolePlayingTips.com.
