According to an article that was published in Human Nature, men are less aggressive and compatible when there are no women around. The study suggests that men become aggressive because there are women around.
Researchers first investigated communities where there are more men than women.
Because the study proves that in communities where there are more women, men have a more tendency to violence.
With the results they had, the researchers said:
The study proves that men don't have a tendency to violence but this happens because of his need to find a partner and protect her.
On the contrary, in communities where there are more women, men have shorter relationships and this brings about competition.
The researchers say that these findings clear up the previous researches.
The researchers say that the measurements taken to prevent violence creates a paradox.
