Nope. I hope the study is more complete than that blurb suggests. The blurb merely points out that certain stereotypes exists and then assumes that internet dating preferences are based on those stereotypes. That may or may not be the case, but the blurb doesn't convince me.
For me, the preference has nothing to do with a stereotype. It's purely physical. I like shiny black hair, the shape of asian eyes and the physique that many (though, obviously not all) asian women seem to have. That doesn't mean I am not attracted to women of other races, it's just that I find myself attracted to these same physical features. For example, I prefer caucasian women with black hair and dark eyes. The african american women I find attractive often have straight black hair and almond shaped eyes. I don't know why this is true.
