For decades, the notion that early risers are more productive and have a higher cognitive function than night owls has been widely accepted. However, a new study challenges this notion, suggesting that night owls may actually have a superior cognitive function compared to their early morning counterparts.

The study, published in the journal Sleep, found that individuals who are naturally inclined to go to bed later and sleep in later in the morning have a higher level of cognitive flexibility and attentional control compared to those who are early risers.

Researchers at the University of Toronto conducted a series of experiments to test the cognitive abilities of 100 individuals, with half being classified as night owls and the other half as morning larks. Participants were given a series of cognitive tests, including tasks that required attention, problem-solving, and memory recall.

The study found that night owls outperformed early risers in tasks that required flexibility and adaptability, such as switching between tasks and adjusting to new information. Night owls were also better at filtering out irrelevant information and focusing on relevant cues.

“Night owls tend to be more creative, open-minded, and able to think outside the box, which are all valuable skills in many areas of life,” said Dr. Michael Scullin, lead author of the study. “Our results suggest that night owls may be more suited to careers that require innovation, problem-solving, and adaptability.”

The study also found that night owls were more likely to engage in creative activities, such as art, music, and writing, and were more likely to be interested in science and technology. These findings may help to explain why many successful entrepreneurs, innovators, and artists are often night owls.

In contrast, early risers tended to perform better in tasks that required repetition and routine, such as following set procedures and performing routine tasks. These skills are valuable in many careers, such as customer service, finance, and administration.

The study’s findings suggest that rather than being at a disadvantage, night owls may have an advantage in certain areas of cognitive function. However, it’s important to note that the study’s sample size was small, and more research is needed to confirm these findings.

In conclusion, while the stereotype of early risers being more productive and having a higher cognitive function may be challenged, the study suggests that night owls may have unique cognitive strengths that can be valuable in certain areas of life. As the study’s authors suggest, “night owls may be more likely to thrive in careers that require creativity, innovation, and adaptability, while early risers may excel in careers that require repetition and routine.”
