"Owls" are more often psychopaths and daffodils than "larks"
Perhaps sleep and wakefulness has a huge impact on the character: in particular, people who are likely to stay awake at night, often manifested anti-social traits such as Machiavellianism, psychopathy and narcissism. This conclusion was based on an analysis by scientists from the University of Western Sydney, headed by Peter Dzhonasonom personalities 250 students.
Dzhonason noted that the majority of crimes are taking place at night, in addition, various questionable acts like flirting too rough occur mainly at night. Similarly behave predators - owls and cats. Therefore, it can be assumed that the anti-social, "predatory behavior" and the night life is quite understandable from the point of view of evolution.
However, it remains unclear where the cause and which effect: it is possible that the negative personality traits have led to a preference to stay awake at night, and not vice versa.
