Peter Jonathan of the University of New Mexico in the United States and his colleagues worked together to create a special personality test form, including narcissism, impulse, love of stimulation, love of lying, coldness and good at playing tricks on power and other "dark personalities".
Jonathan and his colleagues invited 200 college students to fill in the test form and put forward some questions, such as how many times they have been in love and whether they will develop short-term relationships.
The survey results show that the higher the score of "dark personality", the easier the men are to win the hearts of women, and the more likely they are to develop short-term relationships.
The Independent said that the typical "bad" man is James Bond in the 007 series of films. However, he is the "popular lover" of almost all women.
Jonathan told the Independent on the 19th: "Bond is a typical 'bad' man. He is too outgoing, likes to seek stimulation, and has killed people, but he is very popular with women."
Although narcissism, impulse, love of lying and other bad characters can help "bad" men win the hearts of women, these characters run counter to the excellent virtues advocated by the traditional society.
The survey report said that if these bad characters are too extreme in a person, the person will become unsociable and be left out by everyone.
Strangely, many girls like the "dark character" of "bad" men, and feel that they are more masculine because of this, and have a higher chance of breeding offspring with them.
As a result, the "dark characters" of "bad" men will be passed on to the next generation more smoothly. This may explain why some bad characters can always exist in human character.
Coincidentally, David Schmidt of Bradley University in Illinois, USA, conducted a survey of more than 35000 people from 57 countries. The conclusions reached are similar to those of Jonathan and his colleagues.
Schmidt said: "The 'bad' men are more willing to pursue women actively and like to develop short-term relationships. These characteristics are not limited by culture or country, and are the same everywhere."
Barbara Oakley of Oakland University in Michigan, USA, commented on Jonathan and colleagues' research and Schmidt's survey that people often say that "men are not bad, women do not love", and these two surveys have proved this to some extent.
Christopher von Luden of the University of California, Santa Barbara, said that two studies confirmed that personality change has a direct impact on human adaptation.
Matthew Keller of the University of Colorado believes that researchers need to further explain why the bad character of "bad" men does not exist in everyone.
