Google scholar is your friend.

Breat feeding is associated with a (small) difference in IQ: https://onlinelibrary.wiley.com/doi/full/10.1111/apa.13139

Just search breast vs formula milk systematic review on Google scholar and you should be able to find loads of studies.

so, this tells me that in studies that corrected for the mother's iq, the difference was 2.6 points. My wife is asian, i am jewish, with a lot of phds in the family. This is an increase of less than 2%. Sorry, but there's no way I'm going to believe a study like that has an error/variance of under 2%. The studies also did not correct for the father's iq. The father is not serving the breast milk, but iq of the mother is not "passed on" through food, so if you're correcting for mom's iq, you're correcting for genetics, and the father is half of that. None of the studies corrected for quality of formula.

Dude, you said there was no research, so I found you research.

What you choose to do with that research is entirely up to you.
