Final answer:
Interviews offer insights that go beyond direct answers, revealing personality traits and social cues, and do not typically provide a complete life history unless serving as a biographical narrative.
Step-by-step explanation:
Interviews can provide various insights beyond simply the answers to the questions asked. They offer a dynamic source of information and can reveal nonverbal behaviors and social factors that influence the interview process. This can provide a window into a person's personality as well as insights into the interviewer's interpretations. Interviews can delve into complex topics that may not result in concrete answers but can demonstrate the participant's perspectives, beliefs, and attitudes. They do not usually provide a person's complete life history unless the interview is specifically designed as a biographical narrative. Sigmund Freud's in-depth interviews, for example, were critical to his development of personality theories and would fall under a method of a case study.
