Nature vs. Nurture
!The long-fought debate of nature versus nurture has been around for more than two
centuries and has fostered other political, social, and racial debates. It has all come down to
nature versus nurture when we raise topics about human development. Human development may
be seen in different perspectives such as a physical, social, and an emotional point-of-view.
Although nature plays an extremely essential role in our development as human beings, nurture
is the more dominant player in human growth. We are predisposed to many unfavourable things
from birth which we have no choice of, but nurture is able overcome those predispositions,
depending on how motivated we are. Nurture is what influences our daily habits, personalities,
and self-confidence.
!From the physical aspect of development, one would immediately assume that nature is
the main force behind physical growth. Many of us are predisposed to diseases such as heart
disease and cancer. Genetic inheritance and innate health are sided with nature and are things we
cannot pick and choose from. For example, cardiovascular disease (CHD) and cancer are the two
most common diseases that are inherited by nature, but can be prevented with the correct
lifestyle choices. Exercising daily, having a balanced diet and a sufficient knowledge on health
and diseases are part of nurture’s doings. The aforementioned actions can be obtained and
accomplished with the influence of one’s family, peers, and more importantly, the society and
media which they have been exposed to. Nature’s predispositions can be overcome and outgrown
by developing habits. Consider heart disease, it can be prevented by running daily to increase
and improve cardiovascular health. Heart disease can also be overcome by eating a low-fat diet
to decrease the risk of heart attack. These two habits are likely to develop and be a part of one’s
lifestyle, depending on the environment they were brought up in. People who come from low
socio-economic backgrounds tend to have less knowledge about healthy behaviour, leading to an
unlikely chance of developing a healthy lifestyle. Where one is exposed to is an important factor
in determining what type of habits and lifestyle one develops, leading to nurture’s influence on
how much we want to eliminate these inborn diseases.
!How we interact with other people is also influenced by how we judge and classify
others. The stereotypes we develop in our minds is an effect of what type of media and people
we are around to. This is purely on nurture’s part as it falls under what we are exposed to after
birth. For instance, men and women base their opposite sex ‘types’ from what they have seen in
movies, shows, etc. and most of the time, women find the ‘jocks’ attractive. The media has its
way of telling us what beauty is through perfume ads and mascara commercials. From here on,
the way we interact with people determines our personalities. On the other hand, our emotional
state is built upon on how much confidence we have. Confidence is not innate, and needs to be
developed within time. Moreover, our successes and achievements are the building blocks of our
self-confidence. What we define as success varies among everyone. What we perceive as success
is dependent on our parents and peers. The lower expectations your parents/peers have for you,
the meaning of success for you is much different from someone who aspiring to be a world-class
surgeon. Also, success is a byproduct of our personalities. A perfectionist may have higher
expectations than someone who is more laid back in life.
!In the end, nurture has the bigger role in what shapes us as to who we are today. Nurture
impacts our physical, social, and emotional growth by affecting our lifestyle, personality, and our
self-confidence. Nurture, plays the dominant role in human growth and developing our
individuality.
