Reply to Baby girls babble their way to bigger vocabularies sooner than baby boys, but it’s not because parents talk to them more, instead parents appear to talk more to young children who themselves are already talking, regardless of their gende by giuliomagnifico
Interesting, but the sample size is very small and they only processed the most talkative few hours a day from each 16 hour daily recording. I'm a little surprised they didn't seem to incorporate how often children were spoken to, rather just what happened in the most talkative moments, which were around 1/8 to 1/4ish of the day each day.
Cool preliminary findings, but this needs way more intensive studies to determine anything with confidence.

Reply to comment by jtaustin64 in Living in a greener residential area increases the diversity of oligosaccharides in breastmilk. This in turn may affect the child’s health, as the oligosaccharides in breastmilk can protect the infant from harmful microbes and reduce the risk of developing allergies and diseases. by universityofturku
The article says the results were independent of socioeconomic status, so they apparently controlled for that, but I'm still a bit suspicious too because we already know that wealth literally improves every aspect of a person's life already.
I think I'd have a fair amount of skepticism unless they proved the direct causal relationship, or maybe if they were still able to find the same correlation when looking at poor rural families and wealthy inner city families without many green areas (I feel like this is rare for wealthy people, but it does exist). I feel like controlling for things like diet, exercise, etc would be extremely difficult in that case too.
