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.
