Parental favoritism (differential treatment)
Parents treating their children differently in warmth, attention, discipline, money or freedom. Some difference is unavoidable because children differ in age and need. Favoritism is the version a child reads as being loved or valued less.
What drives it
Children compare all the time and notice who gets the softer voice, the later curfew, the bigger check. A parent may be responding to an easier temperament or a child who feels familiar, without seeing a pattern at all. For identification it names an unequal share a family may never say out loud.
How it shows
Work
Adults who were the less favored child may work hard for a boss’s approval and feel crushed when a peer is singled out, or stop competing at all.
Relationships
One child’s report card goes on the fridge and the other’s goes in a drawer. Years later, grown siblings disagree on who was the favorite, and holidays carry the old scorekeeping: who got help with a down payment, whose kids are at grandma’s most.
Self
Notice which child is easier for you to be with, and what you do differently with each in tone, time or patience over an ordinary day.
What tells it apart
Family roles (golden child, scapegoat, lost child, mascot): Family roles such as golden child and scapegoat are fixed parts in a family’s system. Differential treatment may be milder and more ordinary, a shift in warmth or rules between children, and it can change as they grow.
Sibling rivalry and conflict: Sibling rivalry happens in families with very even treatment too. Favoritism is more likely part of the picture when the fights keep returning to who gets more from a parent.
Scapegoating: Scapegoating loads blame onto one person to relieve the group. Favoritism is more likely when one child gets extra warmth while the others are not blamed for the family’s troubles.
A test
List what each child got from a parent last week: time alone, praise, help, discipline, money. Differences that follow age or need, where the children can see the reason, are more likely ordinary. A gap that runs the same way across most of the list, and that a child has named out loud, may point to favoritism.
Questions to carry
- When did one of my children last get a softer answer than the other would have?
- Which of my children reminds me most of myself, and how does that change how I treat them?
Go deeper
- Read: The Kazdin Method for Parenting the Defiant Child, Alan E. Kazdin with Carlo Rotella, 2008. Written for parents by a Yale psychologist who spent decades testing parent management training: praise and small rewards for the behavior a parent wants to see, built up in small steps. That approach has many controlled trials behind it with children referred for defiance and aggression, though Kazdin's own 1997 review said questions remained about how large, wide and lasting the effects are. The book itself does not walk through the studies. It carries the Association for Behavioral and Cognitive Therapies' Self-Help Seal of Merit.
How strong the research is
moderate. A 2025 meta-analysis in Psychological Bulletin (Jensen and Jorgensen-Wells), drawing on 30 papers and 14 data sets with 19,469 participants, found that mothers and fathers both tended to favor daughters and children who were more conscientious and agreeable, and gave older children more freedom. Child age and parent gender made little difference. In 151 pairs of young adult siblings (Jensen, Whiteman, Fingerman and Birditt, Journal of Marriage and Family, 2013), the sibling who got less support than the other reported more depressive symptoms, and bigger gaps went with less closeness between siblings. The data are correlational, so they cannot say why parents favor or which way the effects run.
