When it comes to asking who is more aggressive, scientists are clear about it. According to Dr. Thiago Perez Bernardes de Moraes, anthropologist and researcher at the Universidad Argentina John F. Kennedy , the violence it is a constant in all societies, to a greater or lesser extent, "however, in all of them, men show a more aggressive behavior than women".

A fact that confirms it

In his study entitled "Why do men exhibit more aggressive behavior than women? For an evolutionary anthropology of behavior ", the researcher provides an interesting reference that illustrates this masculine propensity: the demographic data of prisons around the world.

According to data from the United Nations Organization of 2012, of the 8,570,051 recent prisoners, only 4.4% are women, while an overwhelming percentage of 95.6% are men. Despite cultural diversity, this unequal proportion of men and women in prisons is reflected throughout the world.

Throughout the world, adds Dr. Perez Bernardes de Moraes, men have proven to be more violent, practice more crimes, go to war and have greater taste for sports. violent .

To explain this masculine tendency to aggression, the anthropologist points out that it can be found on two levels: through the evolutionary past of our species, in sexual selection, regarding the burden of the parents and the selectivity of the females. Both seem to have exerted pressures in the sense of composing aggressive psychological tendencies.

Hormonal reasons

Another scientist who has studied the subject is the British psycho-endocrinologist June Reinisch, who found evidence in defense of the hormonal argument. Over a period of five years, Reinisch studied 25 children born to women who had taken synthetic progestin.

"It has been proven that hormones change the brain's own geography," explains the expert. "Mainly, the differences occur in the hypothalamus and in the preoptic brain regions, which are curiously connected to the reproductive functions, in those specific areas, men have larger neurons."

Although many scientists believe that the tests are inconclusive, they are convinced that aggression can also be attributed to the male hormone testosterone.
