Being “nice” may in part be due to your genes, according to a new U.S. study in the journal Psychological Science.
In “The Neurogenics of Niceness,” published online on March 28, researchers at the University of Buffalo and the University of California, Irvine, found a connection between “kind” and “generous” behaviour of 711 study subjects, and versions of receptor genes for two hormones that have been associated with niceness in previous laboratory and close-relationship research.
Lead researcher Dr. Michael Poulin, of the University of Buffalo, told Postmedia News the study also could apply to Canadians, especially those of European descent.
There are also similar findings of studies in Israel, Denmark and Switzerland, he said.
“Our findings are consistent with the possibility that oxytocin and vasopressin are part of the biological underpinnings of this caregiving system,” says the study.
The hormones oxytocin and vasopressin have been linked to the way individuals treat each other.
