Problem: Letting contemporary psychology be a guide for deciding what individuals, ideas, and events to include in a history of psychology also serves to limit personal bias. Most textbook writers in the modern era work hard to present the material in as fair a fashion as possible, although an author's own interests and expertise cannot help but color that presentation. Even when we let contemporary psychology dictate content, there remains the question of how much detail to include for any topic or person. Seldom, if ever, is a single individual solely responsible for an idea or a concept. Rather, individuals are influenced by other individuals, who in turn were influenced by other individuals, and so on. A history of almost anything, then, can be viewed as an unending stream of interrelated events. The "great" individuals are typically those who synthesize existing nebulous ideas into a clear, forceful viewpoint. Need Assignment Help?
