If you've ever wondered why women and girls in animated films have such big eyes, there's scientific research that explains it.

The psychology of "Giant Princess Eyes" as popularized in Disney movies is why they draw female characters with oversized eyes.

Scientific research has shown that big eyes, tiny chins, and short noses make characters look more like babies, which creates an air of innocence and vulnerability.

A study of 21 animated Disney movies in the Journal of Applied Social Psychology found that, "Attractive characters displayed higher intelligence, lower aggressiveness, and greater moral virtue."

And, "physically attractive characters were more likely to achieve positive life outcomes."
