Males in current industrialized cultures are victims of advertising and consumerism to the point that their cognitive levels of sex drive seek thinner women than their animal levels would normally think to be desirable.

While I'd agree with that summary, the test of hip:waist ratios was repeated in Indonesia (using silhouettes and not photos) and arrived at exactly the same results. I'm not sure of which part of Indonesia they located their testing but not much of Indonesia would be described as an industrialised culture. I suspect there's an opening for a PhD student (with a travel bug and a lot of financial support) to try the tests in as many far-flung and nonindustrialised culture as possible, to see how universally the results apply. Getting it past the ethics committee might be interesting.
