Recent post on /r/Showerthoughts brought this up, was wondering if there is any actual proof for this? On average Sweedish girls do seem to be much more attractive than English girls.
I feel fairly confident writing this off, even without digging too deeply into the specifics of history.
Why? Simply, "gorgeous" is not a constant, and is in fact a constructed and mutable idea. Even if Scandinavian women do in fact match current Western standards of beauty better than others (which is unproven as far as I am aware), the features that we consider attractive today would likely not be read as equally beautiful to Europeans just a century ago, much less a millennium ago.
Perhaps someone with specialization in Norse history can attack the specific historical issues, but I don't think the idea itself holds any logical water in the first place.
hi! There's lots of room for more information on this question, but FYI, this question has come up several times. It hasn't got much traction so far; here are previous threads for what they're worth
