Because an audience identifies most strongly with the Main Character, choosing a Main Character Domain is like asking your potential audience, “Where’s your mind at?” This Domain describes the realm in which the Main Characters operates. Each potential “Class” in the Main Character Domain, therefore, provides a completely different mind set for the Main Character.

In Dramatica Story Theory, “Psychology” is an internal process, describing problems which come from the ways in which people think. When Psychology is chosen as the Objective Story Domain, the problems that affect all the characters will stem from manipulations and conflicting processes of thought. As opposed to the fixed attitudes described in the Mind Class, Psychology is about problems which arise from manners of thinking. For example, an Objective Story Domain of Psychology might be about the problems caused in a regiment that has been overly trained to follow orders or in a dysfunctional family which is trying to manipulate each other into a nervous breakdown.

In Dramatica Story Theory, “Mind” is an internal state, describing problems which come from fixed attitudes. When Mind is chosen as the Objective Story Domain, the problems that affect all the characters will stem from internal attitudes and fixations. For example, an Objective Story Domain of Mind might be about how prejudice affects a town or how a humiliating memory affects a kingdom. In contrast, Universe and Physics Objective Stories deal with external states and processes. A selection of Mind as the Objective Story Domain specifically means that the source of the difficulties between all the Objective Characters is best seen as a problematic state of mind.
