I suppose the point being made is that enough time has passed for the study to have been properly validated; as the parent comment points out, lots of issues have been found with it.

I'm not familiar with the research here so I can't say either way. But a preliminary google scholar search turned up a lot of articles which seem to suggest that breastfeeding has a bunch of positive impacts on numerous intelligence and general well-being metrics.

The article itself has been cited 209 times according to google scholar [1], and this study [2] (cited 400+ some odd times) seems to accept some of the propositions made in this paper as givens.

Anyway, I think it would have been interesting if the null hypotheses here weren't rejected. I kind of expect evolution to have optimized human breastmilk over alternatives for infant development.

That, and the fact it then isn't newsworthy.

A single data point isn't science. It -might- be news, if it was a super recent data point (though, obviously, requires peer review and replication). This is neither.

Old stuff is reposted here all the time. If it's interesting to the HN community, it's news.
