I like women with nice boobs / ass and don't mind them having a couple of pounds extra; but the media / teens today prefer anorexics. I also know a couple of women that prefer skinny / waxed males (metrosexuals), although the stereotype for attractive males has included for centuries muscles and a reasonable amount of body hair.
I'm sceptical as to how scientific this study can be, when as you say "beauty is in the eye of the beholder". A measure of beauty changes over time and from culture to culture. I'm sure, if you selected a different data set of beautiful people you could prove the exact opposite.
Sure, but if you selected your data set, it wouldn't be the least bit valid.
I'm perfectly OK with assuming for now that there are subtle cues that I'm not conscious of, but some instinctive things are tweaking my more overt reactions.
