According to the University of Madrid and the London School of Economics, those who wake up early have more time just to mediocrity. Those who sleep later and wake up later are generally smarter.

Those who sleep late and wake up late have better analytical thinking, conceptual and critical. Despite some exceptions, such as Thomas Edison and Ernest Hemingway, the morning people are generally good servants while night people are better at more intellectual, creative, scientific, and artistic work. Famous night owls: Charles Darwin, Winston Churchill, James Joyce, Marcel Proust, Keith Richards, Elvis Presley.

In the study of Madrid, 32% are night owls and 25% are morning larks, the rest do not fit into any category. Some scientists say that night people have superior intelligence due to the recent evolution of human behavior with activities after the sunset since the introduction of artificial lighting that attracts people with mind more curious, restless and inquisitive.

The University of Toronto, however, shows that morning types are happier – which is consistent with minds less curious and inquisitive. Another interesting fact is that the morning types feel healthier than night owls – plus more adjusted, since the expectations of the society are more organized around the time of a typically morning person. Another explanation for the greatest happiness of the morning type may be that the nocturnal type body clock comes with a kind of social jet-lag.

Another study, this one from the University of Rio Grande do Sul, shows that people with higher intelligence and nocturnal habits are three times more likely to develop depression.
Finally, these studies are in line with the popular quotes “what the eye doesn’t see, the heart doesn’t grieve over”, “do you want to be right or do you want to be happy?” among other quotes much more polemical and aggressive.

“Everything that is really great and inspiring is created by the individual who can work in freedom” – Albert Einstein

“Liberty is obedience to the law which one has laid down for oneself” – Jean Jacques Rosseau

“Ignorance is the necessary condition of human happiness, and it has to be admitted that on the whole mankind observes that condition well. We are almost entirely ignorant of ourselves; absolutely of others. In ignorance, we find our bliss; in illusions, our happiness” – Anatole France
