"Interesting how breastfeeding is the only area of research of which I'm aware that reverses the findings.
In any other research, the biological norm is assumed to be the benchmark, and deviations from the biological norm are measured in impact. Instead, we assume formula feeding as the benchmark, and measure the biological norm in terms of its deviation from formula feeding.
By which I mean - breastfeeding does not enhance development. It is the biological norm. Formula feeding inhibits neurological development."
(Emphasis mine.) The above comment is in response to an article that uses this phrasing: "MRI images, taken while children were asleep, showed that infants who were exclusively breastfed for at least three months had enhanced development in key parts of the brain". [Hat-tip Shayne Wissler]
(tl;dr summary: formula stunts a baby's development.)
