Life Story

A life story is the internalized, evolving narrative a person constructs about their own past, present, and imagined future, giving their life a sense of unity, identity, and purpose.

The concept comes from psychologist Dan McAdams, who proposed that personality is best understood in three layers: dispositional traits like the Big Five, characteristic adaptations like personal strivings and personal projects, and, at the top, the life story — the narrative identity a person builds to explain who they are and how they became that way. Two people can share nearly identical trait scores and still have very different life stories, because the same events can be woven into very different narratives. One person might frame losing a job as the low point that derailed everything; another might frame the same event as the turning point that led somewhere better. That framing, not the event itself, is a large part of what a life story actually is.

This is the most idiographic of McAdams' three layers — it resists the kind of standardized scoring that works well for traits, since it's less about where someone falls on a dimension and more about the meaning they've made of their own particular life. That's also why it's typically studied through open-ended interviews and narrative coding rather than short self-report questionnaires, and why no major personality assessment, TraitLab included, currently attempts to measure it directly.
