What are the advantage and disadvantage of biographical theory?

Advantage: Biographical theory helps to understand an individual's behavior and development by examining their personal history and experiences. It can provide valuable insights into how past events shape a person's current attitudes and behaviors.

Disadvantage: Biographical theory can be subjective and reliant on self-reported information, which may not always be accurate or complete. It may also oversimplify complex human behavior by attributing it solely to individual experiences.
