Direct Link Between Personality and Genetic Map Scientifically Proven
A comprehensive study led by the University of Bristol using data from 1.1 million people has brought to light 1,260 genetic variants linked to personality traits.
A wide-ranging international study led by the University of Bristol has revealed the links between human personality and genetic structure; thanks to data from 1.1 million analyzed participants, over a thousand genetic variants were identified.
Details of the Comprehensive Study
In the project led by the University of Bristol, which is one of the largest studies in the field of human behavior and genetics, the Big Five personality model in psychology was addressed. According to the results published in the journal Nature, data from 1.1 million participants were examined, identifying 1,260 common genetic variants linked to personality.
Independence of Genetic Influence from the Environment
Statistical analyses conducted in a laboratory setting revealed that the effects of genetic variants on personality are independent of family structure and upbringing environment. Examinations carried out on twins and family members showed that the early childhood environment does not alter genetic variation.
The Link Between Health Habits and Genes
Researchers established significant connections between personality structures and health habits using the identified genetic variants. It was observed that individuals possessing conscientiousness genes have lower rates of starting smoking, more balanced body mass indexes, and shorter hospital stay durations.
Social Contact and Lifestyle Tendencies
It was determined that extraversion genes correlated with the risk of COVID-19 infection due to intense social contact. It was also found that individuals possessing openness to experience genes tend toward nighttime activity, and specific tastes such as coffee, wine, and aged cheese.
Future of the Research and Expert Opinions
Genetic epidemiologist Michel Nivard emphasized that the goal of the study is not to predict personality from a genetic map, but rather that the genome is a tool to understand human outcomes. Experts state that the data will play a key role in understanding chronic diseases and mental issues.
