A team of dogged psychology researchers at Yale have finally proven what some of us have been trying to tell them for centuries: "... the ability to make moral judgments has innate foundations and is not just learned from parents."
Of course, the psychologists wouldn't put it this way at all... instead, this is the summary judgment of James Randerson reporting for The Guardian.
Instead the psychologists would rather put it this way: "... infants assess individuals on the basis of their behaviour towards others. This capacity may serve as the foundation for moral thought and action, and its early developmental emergence supports the view that social evaluation is a biological adaptation." So, you see, it's just Darwin all over again.
Here's The Guardian's peek at the story. If you've got the dough, you can read the actual research published in the journal Nature here.
