A study done by Yale University published in the journal Nature offers proof that babies are excellent judges of character.
"Babies are very competent socially," says Kiley Hamlin, lead author of the study. "They can figure this kind of stuff out without people explicitly teaching what's nice and not nice and who's nice and who's not nice."
Babies not only can pick out the good people, but they tend to emulate them, also.
