Study finds out why it’s gross to kiss your sister
Researchers who wanted to find out why it is not only taboo to kiss your sister, but also disgusting, said on Wednesday they have discovered why in a discovery that challenges some basic tenets of Freudian theory.
The instinct evolved naturally and cannot be taught, John Tooby and Leda Cosmides of the University of California Santa Barbara wrote in their report in the journal Nature.
Spending time in the same household and watching your mother care for your brother or sister is all it takes. This is all subconscious, of course, reported the researchers, who worked with Debra Lieberman of the University of Hawaii.
“We went in search of a kin detection system because some of the most important theories in evolutionary biology said such a thing should exist,” Cosmides said in a telephone interview.
“It should regulate both altruism and incest disgust.”
Humans have an inbuilt system that does both, they found.

James keeps coming back to this shit-hole because he’s in love with me. We’re like Sam and Diane, except instead of being a blonde waitress, he’s a grumpy humorless white guy who gets angry at anything he doesn’t understand, which apparently happens quite often.
Thing I could never understand is these guys with their HHHHHOOOOOOTTTTTTT sisters so casual about being around them. My sister was popular, but hell, she had a car, I could understand that.
It could be the next “in” thing.
Modernisation has given us new ways of looking at things. Love is passionate and passion is blind to reason. And since they say “nothing’s impossible”, so you may see this vision very oft in the near future. Brace yourself if you hate it the most.
I personally don’t think that sibling kissing is particularly uncommon amongst early teens. It certainly happened in our family! However, it is something you grow out of.
