I had a question about how adoption fits in to the picture, so two things come to mind:
A) It still exists for adopted kids.
Since it’s not clear what the effect seems meaningless for single children, maybe it doesn’t exist for them.
Maybe older siblings are trusted with more responsibility or specifically watching out for younger siblings, and that has way more effect than anyone expected. This would be a pain to test, but one might try to check by seeing if the gaps between the ages of kids matter. It’s a pretty specific hypothesis though, so maybe it’d be something else about interacting a lot with younger kids while young (but older).
B) It doesn’t.
That might mean it has something to do with birth, as opposed to differences in how later/earlier children are raised.
I did a search on the first born more intelligent query and go a hit to some article published in late 2016 or early 2017 -- news paper reported on the study in Feb 2017. What the hypothesis seemed to be was that parent interact with the first child differently than the later children and provide a more mentally stimulating environment for that child.
If so any bets on when the first law suit for compensation by the younger siblings will be filed for a great share of any inheritance? (semi-joking...)
I was reading through the comments on “Advances in baby formula” and I noticed 2 claims: babies that are breastfed have higher IQ, and mothers breastfeed less with later children.
If so I wonder if that might not be traced back to immune systems—breastfeeding allows the baby to develop a strong immune system I think given the baby can borrow from mom rather than developing the response alone.
Just wild guesses.
