Robert Plomin is great!😃 Thank you for sharing this article with me :) I don't have an appointment with the hairdresser for the next two weeks, but already got something to read during my next hair treatment :P

Jokes aside ...

Over the past few years quite a few studies have been looking into the genetics of The Big Five Dimensions. Although. the ones I have come across mostly correlate the genetics of personality with psychiatric disorders (not even extroversion escaped- which genetic variation correlates with ADHD ^ref.). You can imagine when it comes to neuroticism ^ref. ! So, yes, there is now evidence of genetic variations underlying our personality traits.

Nevertheless, twin studies suggest that genetics and environmental factors are equally important when it comes to the formation of personality ^ref.

It was concluded that despite sharing the same genes, their different environment, parents rearing practices and education do bring changes in their personalities

Finally, the days when it was believed our personality is fixed are gone. It is now understood for example, that we become more agreeable as we age, and less Open to Experience as the years go by ^ref.

Thanks a lot for stopping by once again, and this time, taking the time to do the test :D

All the best to you always!
