Well done! Does assortative marriage bring together certain birth order positions in certain combinations?
How about a cumulative eg. grandpaternal etc score for paternal age effects? How about dad’s dad age minus the difference with mum’s dad’s age. I’m serious. I don’t like this first born social advantage thing it just damn grinds my gears lol.
First borns sabotage younger borns with their school germs ‘n shit more like it.
Is there any advantage in this social game to having younger siblings? Or only from having fewer elder ones.

Thanks anyway.
Unfortunately, we don't have the data for grandparents!
