Anyway, I don't want to defend it as science - it's an article on the internet. But the flaws in the reasoning definitely are not obvious to me, as they seem to the first commentator. Would be interested to hear more details.
Edit: OK, I counted the "sexy" occurrences, too. Did not bother me much - it is clearly written in "popular science" tone, not "hard science" tone.
That's where I stopped. There's just no rigor in there.
This point did not bother me much, because it seems unlikely to me that there are actually such cultures (where men don't find breasts sexy). Would be interested to learn more about one such culture. For all I know, there might even be cultures where women don't have breasts? I also just remembered those women that put rings around their neck to elongate them - clearly there are a lot of subtle points to consider...
I also don't take issue if people decide they are not interested in that particular subject. However, I take issue with people claiming evolution theory is nonsense, as the original commentator did.
Well, he's using the word "sexy" to mean what it means. That is, marked by or tending to arouse sexual desire or interest. I found it rather refreshing that someone was using sexy to mean "sexy", rather than to mean popular, or cool, or useful, or profitable.
How does the article "purport to be scientific"? I read it as interesting speculation. It doesn't claim to be based on rigorous empirical evidence; it just claims to be interesting. And clearly a bunch of HN readers agreed.
In general it sets off the crackpot alarm for me which means that I take anything else said therein with a grain of salt. One so large, as it were, that it wasn't even worth continuing to read after a certain point.
