Definition

Identity is the operative answer to “who am I when it costs something?” — not the résumé, not the mood of the day, but the default script the nervous system defends.

Origin

Psychology and philosophy. William James distinguished the I (experiencing self) from the me (known self). Narrative identity research (McAdams and others) treats identity as a life story under revision. Social psychology adds role identity — parent, boss, expert — each with its own permissions.

Mechanism

Identity updates when three inputs align:

  1. Named tension — the gap is written, not felt-only.
  2. Repeated evidence — structured logs that the new self already acted once.
  3. Audience — others mirror back a role you are trying on (performed identity) until it stabilises.

When those inputs conflict, you get incoherence — stated values and behaviour diverge (identity coherence). McAdams and McLean treat narrative identity as an internalized life story integrating reconstructed past and imagined future; redemption and agency themes correlate with adaptation in cross-sectional work — causal direction between story features and well-being remains an open research question.

Applications

Identity work targets which version shows up under cost (parent, expert, pleaser, leader) and whether that version matches declared priorities — not mood or job title alone. Domain map: Identity.
