The Early Bird Really Does Get the Worm

If a large proportion of people are evening types, why do most companies insist that everyone come to work early?

Positive attitudes toward morningness are deeply ingrained. In Germany, for example, Prussian and Calvinist beliefs about the value of rising early are still pervasive. Throughout the world, people who sleep late are too often assumed to be lazy. The result is that the vast majority of school and work schedules are tailored to morning types. Few people are even aware that morningness and eveningness have a powerful biological component.
