University of Edinburgh psychologists made a research about the role of the genes in determining the character traits as self control and the decision making. They reached that the genes have bigger role that was thought before.
A study of more than 800 sets of twins found that genetics were more influential in shaping key traits than a person’s home environment and surroundings.
Psychologists at the University of Edinburgh who carried out the study, say that genetically influenced characteristics could well be the key to how successful a person is in life.
The results were then measured according to the Ryff Psychological Well-Being Scale which assesses and standardizes these characteristics.
By tracking their answers, the research team found that identical twins — whose DNA is [presumed to be] exactly the same — were twice as likely to share traits compared with non-identical twins.
Psychologists say the findings are significant because the stronger the genetic link, the more likely it is that these character traits are carried through a family.
Researchers found that genes affected a person’s sense of purpose, how well they get on with people and their ability to continue learning and developing.
