Scientists have find oneself grounds that backs up the old " once a beguiler , always a cheater " rule when it comes to stay put faithful in relationships .
Researchers from the University of Denver wanted to look at whether unfaithfulness in a premature relationship was a risk factor for unfaithfulness in the next relationships . To do this , they search at 484 people in mixed - gender romantic relationship , and asked them about their sexual activities outside of their current family relationship ( whether they had been cheating or not ) as well as whether they were suspicious their partners were cheating .
They then followed these people through from this family relationship to their next relationship , to quantify whether people who said they ’d cheated in the first relationship went on to rip off in the next one .
The study , which keep abreast them over a five - year period , found that people who cheated in their first family relationship were three times more probable to cheat on their next partner than those who stayed close .
The study , publish inArchives of Sexual Behavior , also found that those who suspected their first partner of cheat were four time more probable to have misgiving that their next partner was cheating .
Strangely , people who knew for certain that their first partner had betray , rather than just suspect it , were twice as probable to report that their subsequent partner had also chisel .
The author publish that the written report , aptly titled " Once a trickster , Always a trickster ? Serial Infidelity Across Subsequent Relationships " , present that former cheating was an important risk of exposure gene for infidelity in the next relationships . Basically , if they have cheated before , there ’s a much high chance that they ’ll do it again .
The psychologist controlled for demographic risk factor , and controlled for gender and matrimonial status . So if they cheat in their first kinship with someone they were n’t marital to , they were still more likely to jockey in the second family relationship even if they were married this time .
The authors acknowledged that the sample distribution sizing was minor , and that further study needed to be done , including research on other eccentric of relationship than strictly motley - gender relationship . However , they trust that the study could lead to refreshing interventions to foreclose sequent infidelities in relationships .
