Who has betrayed once will do it always? According to science, yes, especially if there are some factors that predispose betrayal. Betrayal is difficult to overcome and we refer not only to the betrayed person, who should forget, but also to the betrayal, who hardly repeat the mistake. According to a recent scientific study, in fact, those who once betrayed will do it again in the future, even with a new partner. In the same way, those who are betrayed will fall back in love with someone who will betray him. Let's see why.
The study that revealed this truth about betrayal was published in the archive of sexual behaviors and was based on a sample of 484 people, all in a love or married relationship. Participants were asked whether they were betraying their partner at this time and whether they had done so in the past or suspected they were betrayed.
From their answers it became clear that those who had betrayed their partner earlier had the tendency to do it three times more than those who had always been faithful in the past. Also, those who had been betrayed in the past had twice the opportunity to create a romantic relationship with someone who would betray them, despite their very strong suspicion for their new partner.
According to the authors of the study, traitors, once they realized that they were able to lie, would have tended to do it again. Of course, it is not always the case, there are other factors in the game, such as staying in relation to betrayal, the will to do things to work, and the kind of betrayal (one night bet, serial betrayal or parallel bond).
In short, if you're betrayed, maybe you can try to give the betrayer a second chance, but keep your eyes open!
