Naked

This "Study" is so full of shit.

Humans for the longest time of their existence have been running around mostly naked.

Go to any indigenous tribe in the world and you see naked women all over the place. Nobody thinks of them less there.

Actually, dressing up people, being all prude about nudity, made sexual fetishes even possible.

No amazon tribesman would glee over a playboy.

So that men react that way towards women wearing less clothing (if they do so in the first place) it is because we are used to see people covered up all the time.

And it can also not be inherently as tribal human beings don't have that sort of reaction.
There is a lot culture influence in our perception of things.

It's funny since it is a key argument from feminists that culture influences our perception of women etc.

But they kinda always come to the wrong conclusion.
