OREANDA-NEWS. The tendency to change can be laid down genetically. Such conclusions were reached by scientists at the University of Oxford. They found out that infidelity is associated with the work of a variant of the DRD4 gene, which is responsible for the receptors that produce the pleasure hormone

Experts examined a group of 180 volunteers, finding out the details of their personal lives and studying their DNA. It turned out that those participants whose form of the DRD4 gene was long were less sensitive to the pleasure hormone. Such people needed more sexual contacts to get the same reaction as the owners of the short version of the gene.

The research showed that volunteers with a long gene often had an affair on the side, and those with a short DRD4 changed twice as often.

Their colleagues from Canada found an explanation for why some people are annoyed when someone makes minor and repetitive movements next to them. A group of scientists led by a psychologist from the University of British Columbia, Sumit Jaswal, called this deviation misokinesia and noted that every third person can be affected to one degree or another.

Researchers conducted a series of experiments with more than 4 thousand volunteers to find out what effect this disorder has on them and what exactly it manifests itself in. Scientists have come to the conclusion that misokinesia often goes hand in hand with misophonia — a hatred of certain repetitive sounds. In addition, this phenomenon causes a different reaction in everyone — from mild irritation at the sight of fuss around to fits of rage at the slightest hint of annoying movements.
