Who we are and who we become may be dictated by our genes – at least partially. A new study links a variety of gene variants to various personality traits and lifestyles. These findings displayed patterns across large demographics, although experiences and surroundings still play a pivotal role in individual development.
More than 1,000 gene variants are associated with personality, including at least 800 not previously linked to it, according to a study published in the journal Nature. These genetic variants also “partially predict mental and physical health, longevity, education, career paths and outcomes, and even how people are perceived by close others,” said a release about the study.
While scientists have known that a variety of factors, including DNA, could affect personality, the “challenge has been deciphering the specific pathways through which a genetic blueprint nudges the direction of a person’s life”, said The New York Times.
Of course, experiences can also shape personality. Genetic variants linked to openness “predicted that a person would move to more cosmopolitan neighbourhoods”, but “living in those neighbourhoods may reinforce and further shape that same trait”, added the release.
Genes obviously “influence our personality predispositions”, Professor Michel Nivard, a genetic epidemiologist at the University of Bristol and a senior author of the study, told ScienceAlert. “But there are clearly also substantial environmental causes of personality that collectively explain the majority of individual differences.”
