Personality psychology is one of the few disciplines of the social sciences that allows for focus on the individual and interviewing subjects is exactly the way in which this goal can be attained. In a 1986 article, Kenneth Craik identifies laboratory methods, observer judgments, personality scales, and projective techniques as the four most continuously used research methods since the early twentieth century. The goal of any technique is always to remain consistent, but this intent, while well meaning, is impossible. People are dynamic and that is precisely what makes them so interesting to study. An individual can not be frozen in one time or place to be analyzed.
People change over time and most certainly change depending on their surroundings and situations.
The present research is an attempt to freeze the subject in many different areas of their life and see where they may come together. Repeating the survey several times over a span of time may provide more definitive information because a person is better represented when seen as changing. Relationships change and personalities change, but this cannot be contained in a one-time questionnaire. Projection from the surveys would also provide an interesting twist to the study. Allowing people to project into the future about themselves in terms of their own personality and possibly even on what kind of relationships they see themselves having later in life.
