Notably, they didn't control for social effects by looking at female and male sibling pairs with an age difference of 10-18 months. How much of this is parents favoring the male sibling?

- Mary-Jane 8y agoShouldn't they have monitored both groups, using twins raised together as the control group?
- tofof 8y ago"repeated their analysis" This effect exists in twins raised as singletons and twins raised with their brother.
