As Elvis famously croon : “ Wise human beings say , ‘ only fool rush in . ’ But I ca n’t aid fall in love with you . ” It ’s both a romantic birdcall and , according to a unexampled study , a monumental reddened flag – as it become out that “ cannonball along in ” to love may correlate with a higher luck of unfaithfulness in relationships .

With the elision of aromantic folks or the extremely ill-starred , most of us will “ settle in beloved ” at least once in our lives . The process and experience is unlike for everyone : for some of us , it ’s a gradual and rare realization ; for others , it ’s an quick and passionate boot . However it comes to you , though , so far appear to be something of a unique character trait – one that researchers have come to know as “ emophilia ” .

“ crucial individual divergence when falling in erotic love pertain to how easily ( i.e. , how quickly ) and often ( i.e. , how many times ) one falls in sexual love , ” explains the study . “ These two factor ( i.e. , how easy and often ) reflect one intercorrelated phenomenon , which [ is ] denote[d ] emophilia . ”

“ The two factor of emophilia ( i.e. , easy and often ) are [ … ] normally collapsed into one dimension , due to the high correlation between them , ” it add up .

So far so good – but it ’s important to note at this stop that not everyone is convinced that “ emophilia ” is a material affair . In fact , the researchers themselves become into the unexampled subject area with a healthy sexually transmitted disease of disbelief : “ The research on emophilia that has been convey is quite limited , with few studies , all of which are conducted by or in collaboration with [ social psychologist Daniel ] Jones , ” they head out in the theme , “ and most of them let in North American sample . ”

“ pass the riposte crisis in psychological science , it is crucial that findings are supported by freestanding studies , ” they publish . “ Further , cross - cultural field of study are need to establish emophilia as a universal trait . ”

The new sketch does go a picayune way towards remedying this , being carry out among Norse and Swedish volunteer rather than Americans or Canadians . It ’s a variable that might have prove crucial to turn out the existence – or otherwise – of the phenomenon , as “ love ” , and our ideas around the conception , are known to bedependent on acculturation . Consider the popular mind , for example , that amatory love should go hand - in - hired man with friendship and comfort – characterizations that one 2011 study says are well-nigh unknown in , say , Russia or Lithuania , where “ love ” was suggest to be conceptualizedmore as a impermanent " fairytale"than in American player .

essentially , before the researchers could start investigating whether emophilia was linked to unfaithfulness , they first had to verify it was really a thing for everybody , rather than just being a quirk of North Americans . So , using paper advertizing , they levy more than 2,600 report participant and sent out online view measure romanticist info , personality trait including the “ dark triad ” and “ braggart five ” clusters , and levels of emophilia .

The latter category was investigated using the Emotional Promiscuity Scale , or EPS : a “ two - factor in scale [ that ] measure how often and easily a someone fall in love , ” the researcher explain . The first termination was encouraging : a fast statistical depth psychology of the EPS responses confirmed that it ’s a pretty reliable measure for emophilia .

That control , the team be active on to inquire the links , if any , between emophilia and other personality traits . For all you hopeless romantic out there , the results may be assure : while emophilia had a small positive correlation with Machiavellianism and psychopathy , and a slightly stronger one with self-love , it was also had a small positive coefficient of correlation with plus traits like extraversion , agreeableness , and receptiveness .

The principal question , though , was how emophilia affects your love animation – specifically , is it positively associated with a soul ’s number of romantic relationship and times being unfaithful ? The answer seems to be yes .

As the team place out , this may not be surprising . “ The inclination to diminish in love life easy and often [ … ] might head the person to engage in new amatory relationships more frequently , ” they compose , while “ falling in beloved easily and often may also explain emophilia ’s association with unfaithfulness , as it may moderate the individual to explicate romantic feelings toward someone outside their relationship . ”

It ’s depressing news for those who bed love – but do n’t lose heart just yet . Because of the way the work was conducted – being cross - sectional , and base entirely on ego - reporting – it ’s impossible to say for sure that emophiliacausesinfidelity or higher numbers of relationship . Indeed , as the investigator themselves point out , it could be precisely the opposite .

“ It might be that instead of emophilia causing the telephone number of kinship / affair , the direction could be opposite , in which wads on emophilia were at least in part a upshot of the number of relationship / affairs , ” they suggest . “ One can reason that those who have been in many relationships , and/or cheated many time , might reason in hindsight that they might also have been in love many times , as it is common , and it is probably more socially desirable , to view relationship formation / cheat as being relate to love . ”
