If your boyfriend is always talking about how great he is, a new study may encouarge you to be wary.
Researchers have revealed that men with dark personality traits – including Machiavellianism, narcissism and sadism – are more likely to be repeated cheaters.
In psychology, narcissism is generally characterised by grandiosity, pride, egotism and a lack of empathy for others.
‘People with dark personality traits can establish short-term relationships more easily because they generally have low expectations about their future partners, especially in the case of men,’ said researchers Laura Ferreiros and Miguel Clemente from Universidade da Coruna.
‘Additionally, even if their initial expectations are high, they are willing to reduce them to have more partner options.’

Previous research has shown that people with dark personality traits tend to be unsympathetic, manipulative and violent.
However, until now, little research has looked at a link between dark personality traits and young people’s intimate couple relationships.
In their new study, the team set out to explore this link by surveying 308 participants aged 18-25, 78.3 per cent of who were women and 21.2 per cent of who were men.
Participants were quizzed on their sexual practices and tendencies towards partners, as well as their moral disengagement and dark personality traits.
The ‘dark’ traits the researchers assessed were Machiavellianism, narcissism, psychopathy, sadism, moral justification, euphemistic labelling, advantageous comparison, displacement of responsibility, diffusion of responsibility, distortion of consequences, dehumanization, and attribution of blame.
The survey results revealed that men obtained higher scores than women both in moral disengagement and dark personality traits.

People who were unfaithful or who consumed pornographic content also scored more highly for these traits, except psychopathy.
Meanwhile, men with higher levels of dark personality traits were also more likely to cheat on their partner – especially repeatedly.
‘Infidelity is highly related to the presence of dark personality traits, unrestricted socio-sexuality, and having more sexual partners,’ the researchers added.
The study comes shortly after research revealed that highly narcissistic individuals climb the career ladder to become head of their company 29 per cent faster.
Researchers compared levels of narcissism in 241 CEOs around Italy, as determined by questionnaires, with their employment history.
The academics found that the executives with the highest scores for narcissism got promoted quicker, regardless of whether their firm was a family business or not.
This suggests narcissistic individuals benefit from the toxic personality flaw when they’re aiming at becoming head of their company as fast as possible – although the experts don’t know why this is.
