3. Genetic Study
3.1. A study was done at Edinburgh University where they researched if genetics had a greater impact on our personality and how successful one is in their life.
3.1.1. In this study a group of twins were diagnosed, the results they found were that identical twins are twice as likely to share similar personality traits than fraternal twins. This implies that their DNA has the greatest impacts.
3.1.2. One major factor they discovered was self control, they found a big genetic difference in peoples ability to restrain and control themselves and how they react to confrontation in a positive way.
3.1.3. "Previously, the role of family and the environment around the home often dominated people's ideas about what affected psychological well being. However, this work highlights a much more powerful influence from genetics." (Professor Timothy Bates, Edinburgh University)
