Babies Like Nice Guys

Can't embed it, but the NY Times has a video of a study at Yale that shows babies prefer nice characters:

In one of our first studies of moral evaluation, we decided not to use two-dimensional animated movies but rather a three-dimensional display in which real geometrical objects, manipulated like puppets, acted out the helping/hindering situations: a yellow square would help the circle up the hill; a red triangle would push it down. After showing the babies the scene, the experimenter placed the helper and the hinderer on a tray and brought them to the child. In this instance, we opted to record not the babies’ looking time but rather which character they reached for, on the theory that what a baby reaches for is a reliable indicator of what a baby wants. In the end, we found that 6- and 10-month-old infants overwhelmingly preferred the helpful individual to the hindering individual. This wasn’t a subtle statistical trend; just about all the babies reached for the good guy.

From the associated article:

Socialization is critically important. But this is not because babies and young children lack a sense of right and wrong; it’s because the sense of right and wrong that they naturally possess diverges in important ways from what we adults would want it to be.

And:

But the new studies found that babies have an actual understanding of mental life: they have some grasp of how people think and why they act as they do. The studies showed that, though babies expect inanimate objects to move as the result of push-pull interactions, they expect people to move rationally in accordance with their beliefs and desires: babies show surprise when someone takes a roundabout path to something he wants. They expect someone who reaches for an object to reach for the same object later, even if its location has changed. And well before their 2nd birthdays, babies are sharp enough to know that other people can have false beliefs. The psychologists Kristine Onishi and Renée Baillargeon have found that 15-month-olds expect that if a person sees an object in one box, and then the object is moved to another box when the person isn’t looking, the person will later reach into the box where he first saw the object, not the box where it actually is. That is, toddlers have a mental model not merely of the world but of the world as understood by someone else.

Conlcuding:

Babies probably have no conscious access to moral notions, no idea why certain acts are good or bad. They respond on a gut level. Indeed, if you watch the older babies during the experiments, they don’t act like impassive judges — they tend to smile and clap during good events and frown, shake their heads and look sad during the naughty events (remember the toddler who smacked the bad puppet). The babies’ experiences might be cognitively empty but emotionally intense, replete with strong feelings and strong desires. But this shouldn’t strike you as an altogether alien experience: while we adults possess the additional critical capacity of being able to consciously reason about morality, we’re not otherwise that different from babies — our moral feelings are often instinctive. In fact, one discovery of contemporary research in social psychology and social neuroscience is the powerful emotional underpinning of what we once thought of as cool, untroubled, mature moral deliberation.

But you'll have to read the article for the caveat...
