Dear MEL Topic Readers,
Nature vs nurture: How much of our personalities are determined at
birth?
Was our personality set at birth or developed as we grew? While nature
is influenced by genetic inheritance and other biological factors, nurture is
the influence of external factors, such as exposure, experience, interactions, and
learning. Identical twins share 100% of their DNA, but their key personality
traits, such as openness, conscientiousness, extraversion, agreeableness, and emotional
instability or anxiety, aren’t exactly the same. To your surprise, all humans
are roughly 99.9% identical in their genetic makeup, and the remaining 0.1%
accounts for all individual differences, including appearance, susceptibility
to diseases, and other traits. Also, studies found that the environment, social
interactions, or even significant life events we’ve experienced have a limited
influence on our personality traits. It seems that no one thing determines who
we are or how we behave, but multiple genetic and environmental factors do.
Read the article and
learn how nature and nurture influence our personality traits.
