Does Intelligence Depends More On The Environment Than Genetic Factors by lovelyadeola(m): 7:19pm On Dec 25, 2014
What Factors Determine Intelligence?
In addition to disagreements about the basic nature of intelligence, psychologists have spent a great amount of time and energy debating the various influences on individual intelligence. The debate focuses on one of the major questions in
psychology: Which is more important - nature or nurture ?
Today, nearly all psychologists recognize that both genetics and the environment play a role in determining intelligence. It now becomes matter of determining exactly how much of an influence each
factor has.

First, it is important to note that genetics and the environment interact to determine exactly how inherited genes are expressed. For example, if a person has tall parents, it is likely that the individual
will also grow to be tall. However, the exact height the person reaches can be influenced by environmental factors such as nutrition and disease.

Evidence of genetic influences:
Twin studies suggest that identical twins IQ's are more similar than those of fraternal twins (Promin & Spinath, 2004).
Siblings reared together in the same home have IQ's that are more similar than those of adopted children raised together in the same environment
(McGue & others, 1993).

Evidence of environmental influences:
Identical twins reared apart have IQ's that are less similar than identical twins reared in the same environment (McGue & others, 1993).
School attendance has an impact on IQ scores (Ceci, 2001).
Children who are breastfed during the first three to five months of life score higher on IQ tests at age 6 than same-age children who were not breastfed (Reinberg, 2008).

Interesting topic!
Mathematics, Analytical and Quantitative Reasoning tests, such as in/through games e.g. chess, are very vital factors that help build intelligence.
The environment in which the brain is trained is an important determiner, if not the more important.

Both are mutually dependent, but genetic factor comes first. The intelligence (IQ) is passed first from the parents to the offspring. That's why an intelligent student who does well in Nigeria performs even better when taken to a school abroad. Genetic factor is inherent. Also, I'm not ruling out good nutrition because ''you're what you eat''.
