Research from Semmelweis University detected correlations between preferences in the schedules that the person devotes to sleep and their IQ score.
Are those who live at night smarter?
The smartest individuals tend to prefer the nightlife, at which point their creativity reaches its peak. This is why these people usually go to bed later or have difficulty falling asleep.
Although various research has warned that little sleep has very bad health consequences and can even shorten life, the truth is that there is a relationship between a high level of CI and suffering insomnia.
Rest and hours of sleep play a vital role in animal biology, and this new study provides new variables to consider: sleep patterns and rest times are linked to your cognitive abilities. According to the results, subjects with higher IQ scores tend to be more active at night, while those with more subdued scores tend to go to bed earlier.
Research on sleep cycles and intelligence
The truth is, this type of research always generates controversy. Many analysts agree that the concept of IQ used to measure such an abstract and relative concept as human intelligence is in itself a fundamental limitation. There is no doubt, however, that the night has characteristics that attract certain types of personalities, such as thoughtful people and those who develop their creative potential; profiles that demand a comfortable and mystical atmosphere that the night offers.
Robert bolizs, One of the authors of the research, showed through images of encephalograms during sleep episodes, that there are certain variables directly associated with cognitive exercise in the waking state. For its part, the surveys of H. Aliasson revealed the correlation between sleep intervals and students’ academic performance.
Correlation between scoring in intelligence tests and calendars is remarkable
Other interesting studies on this subject are those carried out by the researcher Satoshu Kanazawa at the London School of Economics and Political Science. Kanazawa pointed out that there are significant differences between predilections in sleep schedules with reference to their score on IQ tests. Subjects with higher scores reported a greater ability to produce at night, while people with more limited IQ levels defined their activities during the day.
As Kanazawa points out, prehistoric humans lived and produced mainly during the day, although the trend reversed, increasing nocturnal activity over generations. It is from this point of view that it seems fair to say that the evolution of the human psyche seems to be gradually linked to the night shift. In summary, Kanazawa agrees that people with more cognitive abilities tend to feel more comfortable fostering personal development at night, showing a “higher level in their cognitive complexity.”
Night owls and mental health
Another research carried out in 2008 and coordinated by the Italian psychologist Marina Giampietro points out that at night people have one lower emotional stability and are more likely to suffer from depression and addictions. This would confirm that the more creative and less traditional minds are for their part the most fragile in the face of certain psychological disorders.
