Women who are highly extraverted are more likely to cheat on their partner, new research finds.
Extraverts are outgoing, social and full of energy.
Introverted women, meanwhile, are less likely to cheat on their partner.
Introverts tend to enjoy more solitary activities, prefer to think before they talk and enjoy focusing their mental energy inwards.
For men, no personality traits were strongly linked to infidelity, the results of two 3-year studies has found.
Instead, the research revealed that your own personality has an important effect on whether your partner cheats on you.
The data from newlywed couples found that partner neuroticism is critical.
People with neurotic partners were more likely to cheat, whether it was the man or the woman.
Neuroticism is a personality trait that is strongly linked to anxiety, sadness, irritability and self-consciousness.
In addition, men with wives who were highly narcissistic were also more likely to cheat.
For the two studies, 227 couples were surveyed and followed over around 3 years.
Along with personality tests, they were asked if they had been unfaithful.
Around 8% of couples admitted infidelity within the first three years of marriage.
The study’s authors write:
“…infidelity may be better explained by partner (versus own) personality.
Given that people’s own enduring characteristics and their partners’ enduring characteristics influence their shared environment, it is possible that people’s partners’ personality traits, specifically, influence the negativity of their shared environment to a greater extent than do people’s own personality traits.”
