I didnt know that was true. Some famous people ive seen called really attractive dont have perfectly symmetrical faces. In fact for some of them its not too hard to notice the asymmetry but theyre still really attractive.. i think the amount that symmetry comes into play might not be as high as other stuff like the shape/size of features, if at all. but ya.
Also for the hair thing i think is just bc some hairstyles look cuter than others depending on the person. Not necessarily middle part for everyone tho is not bad.
I rlly feel like 2023 is a year of a lot of things coming to light. Not just because of this but there was some stuff that happened earlier in the year and i got the impression that that'd be the 'theme' for this year (it feels like since 2020 every year has a 'theme' in some way.) This isnt super related tho but i feel like if there was any doubt that these companies are profit driven and WILL put that above user experiences, even if only for pennies, is largely been confirmed this year.
