This one clearly states that infants induce different attitudes in their parents - for example baby boys being more irritable, making their parents spend less time with them. I don't think it warrants the conclusion that everything is just socialization. I have no opinion on brain differences - it seems unlikely to me, as I think the brain is a rather universal machine that can adapt to a lot of situations (such as being stuck in a male or female body). But what about hormones? Afaik hormones induce behavior changes, and boys have more testosterone than girls? To be sure you could inject all girls with testosterone. This is possible: http://www.oddee.com/item_97013.aspx http://www.oddee.com/item_97013.aspx Should we do it? I also re-read your link about the classroom. It also clearly seems to indicate that boys receive more attention because they demand it. The teachers explanation is "Boys have trouble reading, writing, doing math. They can't even sit still. They need me more." - what if that is actually correct? Are the smart girls really left behind? After all girls tend to have better grades than boys. As I said I find the research interesting and valuable, but crying "sexism" and "girls are being shortchanged" (as they do in their article) seems biased and unnecessary. If you can learn from such research how to better educate boys and girls, I am all for it. If you are interested in continuing the conversation by email let me know, I think this HN thread is too deeply nested already...
