Mater semper certa est, pater numquam.

Surrealia: "The sleeping beauty" (2010)

All searches carried out by scientific bodies reveals that men are sexually unfaithful more than women, in percentage terms; and social perception amply confirms this searches.

Research carried out by non-scientific bodies (survey institutes, online dating sites, ...) says the same things, but sometimes even the opposite.

The male / female ratio worldwide is substantially 102/100, with males not reaching 52% of the world population.

Frankly, it seems to me an insufficient data to explain, considered alone, the marked (seeming ...) preponderance of male betrayals over female ones (a preponderance certainly reduced compared to the past, but still perceived as marked in social practice).

Well, even if we wanted to give for ascertained the greater predisposition to sentimental betrayal by males, what frankly would remains incomprehensible would be the mathematical oddness of this statistical relationship.

In fact, even if we wanted to purify this data from the statistical incidence of prostitution (whereby a large number of males cheating sexually with a rather small number of women) and from the higher percentage incidence of males in the population, would still remains an incomprehensible relationship per capita incidence between male and female infidelity, given that, in the norm (I would say, at least in 90% of cases) males and females cheat with people of the opposite sex.

That is, in other words, if the sexually unfaithful men were more frequent percentually than the sexually unfaithful women, we would have to conclude that, outside of prostituting relationships, women cheat in a smaller percentage than men but with more partners (and this, frankly, would go little it agrees with the female psyche, which tends to favor relationships only with few partners and to invest more in emotional and sentimental terms).

So, in my subdued opinion, the conclusions that can reasonably be drawn from them are only the following:

• males actually cheat only just slightly more than females,
• the males artificially magnify the number of their betrayals (they do this because this numbers, rightly or wrongly, is socially considered a sign of virility) and the males they accredit themselves, like conquests effective crowned with success, also those Platonic attractions in realities never transformed into courtships or, also if transformed into courtships, not crowned with success (they do this because this illusion increases their self-esteem),
• women betray sexuallyt almost as much as men, but tend to maintain a considerable reservedness about their actual betrayals (they do this because their sexual betrayals, even in the absence of a partner, rightly or wrongly is seen socially as a serious sign of ethical lack and lack of respect in against any possible offspring).

All these conclusions (which to me seem stringently logical) in turn inevitably produce a corollary that I would like to anticipate in some way through some statements by Jurists and Geneticists who go to summarize the thinking of the respective professional categories:

• Prof. Maria Rosaria Marella (Professor of Private Law in the University of Perugia): "it appears, from surveys conducted by gynecologists and geneticists, that a percentage that goes from 10% to 15% of children born in the Italian families are not biologically children of the husband of their mother" (2001).

• Prof. Kermyt Anderson, assistant Professor in the Department of anthropology at the University of Oklahoma: "about 30 percent of those men [who actively seek out the paternity tests, because they doubt of their paternity] aren't the fathers" (2006) [... statistics, this one, which I can confirm based on my forensic professional experience ...].

• Dr Bruno Dallapiccola (Geneticist at the University of Roma): "The children raised by a father who is not the real one, in Italy, are almost 10%. Of these, however, only a minority finds out the truth" (2009).

• Dr Alvaro Mesoraca (Geneticist and molecular Biologist of Group Artemisia in Roma): "In Italy, at least the 10% of the children are illegitimate. A percentage, is estimated, that, in recent years, has even doubled" (2012).

That is, in other words, beyond the arid general percentages, males are exposed to the risk of a betrayal far more more qualitatively intense, cruel and lasting than the betrayal to which females are exposed ...
