Here's the article and its key finding:
Why Are Black Women Less Physically Attractive Than Other Women? Why black women, but not black men?

A critique that puts this study in context:
Racist Psychology Today article claims black women are objectively less attractive than other women
The author, Satoshi Kanazawa, is known for racist junk science. He works in the field of evolutionary psychology, which sadly is full of folks passing of their deduction as objective fact to prove their racist and sexist views. He’s obsessed with attractiveness and linking race and intelligence in work that’s been repeatedly debunked. He’s also said he wished Ann Coulter was president on 9/11 so we could have nuked the entire Middle East. Yeah, wonderful guy.
Voices: The Satoshi Kanazawa Study
Note that the results are about what we'd guess with zero data. Asian women, considered the most "exotic" minority, are ranked close to whites in beauty. Native women--at least, alluring Indian "princesses" like Audrey Hepburn, Cher, and Disney's Pocahontas--are third. And black women--widely criticized in our society as fat, loud, and sassy--are a distant fourth.
This is basically a ranking of America's racial prejudices, not of women's "objective" beauty or anything else. It's ridiculous.
