Self-disclosing describes someone who is open about their thoughts, feelings, experiences, and personal life. People high in this trait may find it natural to share what is going on inside them instead of keeping everything private. They often build connection through honesty, openness, and letting others know who they really are.

At its best, this trait can show up as emotional transparency, trust, authenticity, and the ability to make relationships feel more real. At its extreme, it can become oversharing, weak boundaries, or revealing personal information before there is enough trust or context.

A recognizable fictional example is Leslie Knope from Parks and Recreation. She represents someone who shares her thoughts, feelings, hopes, and loyalties openly, often making her relationships feel personal, direct, and emotionally available.
