Resource-Competition Anxiety
Resource-competition anxiety is the fear that a sibling-in-law is competing for a shared relative's finite time, attention, caregiving credit, or eventual inheritance. Family-favoritism research shows differential treatment by parents is real and predicts sibling tension; evolutionary kinship theory explains why the underlying logic — limited resources, non-identical genetic stakes — makes this competition a structural feature of blended families rather than a symptom of any one person's insecurity.
SEE THE PRACTICE
Turn a thought this research explains into one clear move.
THE THOUGHT
“We're the failure couple of the family”
YOUR RECORDED RESPONSE
“I didn’t agree to this comparison game.”
ONE PRIVATE MOVE
On a blank note card, write three columns: “theirs,” “ours,” and “not mine to score.” Fill in one item for each, then fold the card and place it in your wallet or a drawer before the day is over.
How it sounds in your head
The inner script: 'If my brother's wife handles Mom's medical appointments, she's angling to be favorite when the will is read.' The research reframes this as a predictable structural tension around shared, finite resources — not proof of anyone's hidden scheme.
