Smart people prefer to live at night
An investigation from Semmelweis Universitydetected correlations between preferences in the hours that the person spends to sleep and their IQ score.
Are those who live at night smarter?
The smartest individuals tend to prefer nightlife, at which point their creativity reaches its zenith. It is for this reason that these people tend to go to bed later or have trouble falling asleep.
Although different investigations have warned that sleeping little has very harmful consequences for health and it can even shorten life, the truth is that there is a relationship between high IQ level and sufferinginsomnia.
Rest and hours of sleep play an essential role in the biology of animals, and this new study provides new variables to take into account: sleep patterns and rest times are linked to your cognitive ability. As the results show, subjects with higher IQ scores tend to be more active at night, while those with more discreet scores tend to go to bed before.
Research on sleep cycles and intelligence
The truth is that this type of investigation always generates controversy. Many analysts agree that the concept of IQ used to measure such an abstract and relative concept as human intelligence is itself a basic limitation. There is no doubt, however, that the night has characteristics that attract certain types of personalities, such as reflective people and those who develop their creative potential; profiles that demand a comfortable and mystical environment that the night provides.
Robert Bolizs, one of the authors of the research, showed through encephalogram images during episodes of sleep, that there are certain variables that are directly associated with cognitive performance in a state of vigil. On the other hand, the investigations of H. Aliasson revealed how sleep intervals correlate with students' academic performance.
The correlation between scores on intelligence tests and timetables is remarkable
Other interesting studies on this topic are those carried out by the researcher Satoshu Kanazawa at the London School of Economics and Political Science. Kanazawa noted that there are significant differences between predilections in sleep schedules in reference to their score on IQ tests. Subjects with higher scores reported a greater ability to produce at night, while those with more limited IQ levels limited their activities during the day.
As Kanazawa indicates, prehistoric humans lived and produced mainly during the day, although the trend was reversing, increasing nighttime activity as the generations. It is from this point of view that it seems correct to say that the evolution of the human psyche seems to be progressively linked to night hours. In summary, Kanazawa agrees that people with higher cognitive abilities tend to feel more at ease. pleasure in fostering their personal development at night, showing a "higher level of complexity cognitive ”.
Night people and mental health
Another investigation carried out in 2008 and coordinated by the Italian psychologist Marina Giampietro she pointed out that nocturnal people have a weaker emotional stability and are more prone to depression and addiction. This would confirm that the minds with greater creative capacity and less traditional are in turn the most fragile in the face of certain psychological disorders.
