A favorite trope of sleep research is to divide the entire human population into two cute, feathered categories: early birds (also called larks) and night owls. Often, these studies link people's natural sleep patterns—called their chronotype—with some waking behavior or personality trait.
It doesn't take long to see which team more often comes out on top. (Hint: It is the one that catches the worm.) Research says that early birds are happier, more punctual, do better in school and share more conservative morals.
