Do you think God gives this to us when we are born?
New Haven, Connecticut (CNN) -- It is one of life's biggest questions: Are we born knowing the difference between good and evil? Or are we taught our moral beliefs by parents and society?
Philosophers and psychologists have long believed that babies are born "blank slates," and that it is the role of parents and society to teach babies the difference between right and wrong; good and bad; mean and nice.
But a growing number of researchers now believe differently. They believe babies are in fact born with an innate sense of morality, and while parents and society can help develop a belief system in babies, they don't create one. A team of researchers at Yale University's Infant Cognition Center, known as The Baby Lab, showed us just how they came to that conclusion.
Dr. Karen Wynn runs the Baby Lab, and she and her team have been studying the minds and behaviors of babies for decades. About eight years ago they began running a series of studies on babies under 24 months to see how much these babies understand about good and bad behavior.
The first test is the simplest. Show a baby an example of good behavior, and then an example of bad behavior, then let the baby decide what she likes.
