Inc: Research shows that the body’s circadian clock even controls elements of human personality.

Or in non researcher-speak, larks are more charismatic early in the morning, night owls more charismatic later in the day.

According to research recently published in Leadership Quarterly, people tend to be much less charismatic when they’re at a relatively low point in their circadian rhythms, and much more charismatic when they’re at a relatively high point. 

Morning people perceived a speaker to be more charismatic when they viewed a videotaped presentation in the morning; morning people who viewed the same video later in the day found that person to be less charismatic. The same held true for night owls; the same speaker seemed much more charismatic when viewed at night than in the morning. 

In short, it’s easier to inspire morning people in the morning, and night owls at night.
