People who cheat at least once may tend to cheat again due to similar chemical changes inside their bodies, revealed a team of researchers.
Researchers have tried to decipher the reason behind cheating and they claim that some chemical in our brain may be responsible for it. Dopamine is a neurotransmitter in the brain that controls pleasure and vasopressin is a hormone similar to that of oxytocin that is released during sexual intercourse.
‘Dopamine, a neurotransmitter in the brain that controls pleasure and vasopressin, a hormone similar to that of oxytocin may be responsible for cheating.’
A study conducted in 2002 analyzed the dopamine D4 receptor gene in 200 volunteers. In the study it was found that 50% of participants who had the long allele variant of the gene cheated atleast once on their partner. Only 22% of participants who had the shorter variant cheated on their partner.
Similarly, a study conducted by Finland researchers in 2014 reported that participants who have reduced levels of vasopressin hormone cheated on their partner when compared to participants having normal levels of this hormone.
