“My parents always chose my sibling — which means I was worth less.” Jensen et al. (2013) found that adults who perceived childhood favoritism carry measurably lower self-esteem and higher depressive symptoms decades later, even when the favoritism was mild. The wound isn't the old family dinner table. It's the interpretation that got installed there and still runs.

The Science of Adult Sibling Dynamics: Why the Old Roles Never Left
14 scripts this research explains — Most families never vote on who's the favorite, the screwup, or the reliable one — the roles just harden, usually before
“My family still treats me like the difficult one — and I'm starting to wonder if they're right.” Families assign psychological roles in childhood — the responsible one, the difficult one, the golden child — and research shows these roles persist into adulthood regardless of actual behavioral change. Role-lock isn't a reflection of who you are now. It's a family system preserving its own structure, and the person who changed the most gets read through the oldest lens.
The Role Lock
“My sibling only calls when they need something — and I pick up every time.” Connidis (2010) drew the line between affective sibling relationships (mutual, emotional, present) and functional ones (transactional, contact triggered by need). The functional sibling isn't cold — they just experience the relationship as a resource, not a bond. The resentment is real. The script underneath it is: their absence between calls means I don't matter.
