Intelligence Essay, Research Paper
Advances in AI With advances in technology many researchers have become captivated with the pursuit of Artificial
Intelligence. Numerous fields of study have tried to contribute their knowledge in order to create intelligence. However, years
of research have thus far been unable to create human intelligence. The endeavour seems doomed to fail, for a century of
thought which has tried to simply define intelligence has yet to succeed. This lack of a concrete tangible definition does not
preclude its existence but merely points to its complex nature. Human intelligence could be viewed as being as diverse as its
population however this type of analysis leads us to the individual and becomes useless. There is no doubt that there are
universal patterns of what could be considered intelligence and it is these patterns which may give us insight. Because these
patterns of ?intelligence? could be linked to humanity?s evolution, much time is devoted to find what forces or factors are
responsible for them. There are few who would still adhere to a model of Nature vs. Nurture rather substituting the vs. for via.
Both environmental and genetic factors contribute to human intelligence, however which of these, if any, is more important in
shaping intelligence is a source of fierce disagreement. It seems apparent that those who posses higher levels of intelligence are
accorded a certain amount of privilege. Therefore where intelligence comes from is essential in determining the validity of
endowing privilege on those who posses it. Is it the case that the very definition of intelligence is socially constructed in order to
maintain the existing social inequalities? Is it the case that social inequalities are merely a reflection of the variance in intelligence?
Do social inequalities reduce the oppressed ability to develop intelligence? Is intelligence merely a small factor contributing to
the uneven distribution of resources within our world? Is intelligence a product of hard work or just luck? Evolution of
Intelligence Before we can begin to examine the modern day conceptions of intelligence, it is necessary to look at how human
intelligence has evolved. For the purpose of simplicity I am making the assumption that the general theory of evolution is
accurate. That is that human did not spontaneously appear on Earth and are a product of millions of years of evolution.
Therefore it is conceivable that the very way in which we think was once quite different from today?s mode of logic and reason.
Amaury de Reincourt looks at a turning point in the evolution of human intelligence in her article ?Sex and Power in History?. In
this article she examines the rise of patriarchy out of matriarchy. She iterates how this shift was a result of man?s gradual
development of his role in procreation. This marked a mental threshold from magico-symbolic thought processes to rational
thinking. The creation of life was now understood in terms of causality rather than mysticism. From this point forth, all the
female-oriented myths were reinterpreted patriarchally. The cyclical nature of female-oriented thought was replaced by the
linear thought patterns of male-oriented thinking. This further led to the notion of progress and later reflective thought. The
mythology that prevailed under matriarchal rule was replaced by the masculine thought process of rationalism and logic. The
overall effect is that tension replaced repetitive rhythm. This led the way to the concept of time as being unidirectional instead of
the lunar-vegetal cycle which previously set-up the notion of time. History could now be viewed with a beginning, middle, and
an end. This had great significance in releasing man from the endless repetitive cycles of time, which could now be seen as a
linear development with unique moral significance for each step of the way. It is apparent from this article that logic and reason
are not value neutral, they are concepts which are steeped in a particular ideology. What it also inadvertently points to the idea
of interpreting intelligence from completely opposite perspectives. Thinking in terms of cycles instead of our linear modes of
thoughts produces completely different types or patterns of intelligence. It serves as a caution in trying to determine and define
the very slippery notion of intelligence. Intelligence defined The inherent difficulty in studying intelligence is reflected one of
psychology?s maxims; ?the human mind?s greatest challenge is to understand itself?. This has nonetheless not deterred
psychologists in attempting to measure this ambiguous concept. The first to propose and design an intelligence test was Alfred
Binet. He was summoned by the French government to design a test that would be able to alert educators of children who
might benefit from remedial instruction. The test was so successful in determining school performance that it was accepted
throughout the western world. In 1916 Lewis Terman from Standford University adapted it for use with American children. It
thus became the Stanford-Binet Intelligence Test and is the test most commonly referred to when speaking of an IQ test. This
test and others like it take a holistic approach to intelligence. They point to the idea of intelligence as a unified trait. This idea
was expanded in 1927 by Spearman who noticed that all the items on the Stanford-Binet test were correlated and thus
proposed a general factor, which he termed ?g?, of intelligence. He viewed the different items as measuring specific factors he
termed ?s?. The concept that intelligence can be viewed as a singular trait is one that has lost its appeal over the years. In an
article published by the Progressive Labor Party ?Racism, Intelligence and the Working Class?, the authors bring some of the
common criticisms that have be directed at such tests. The political agenda they wish to push clouds some its points but the
overall criticism of IQ tests is that they are designed to measure a particular type of ability defined by the ruling class. In essence
this argument points to the fact that these tests are culturally biased. Hence, the scores are not only indicative of only one
potential pattern of intelligence but furthermore they do not reflect an objective universal pattern of intelligence but rather one
that is socially constructed. The first of these criticism was addressed in the mid 1960?s by J.P.Guilford. He devised a
180-factor model of intelligence, which classified each intellectual task according to three dimensions: content, mental
operation, and product. This theory is the predecessor to Gardner?s theory of multiple intelligence, which was developed, in the
last 15 years. This theory identifies seven independent intelligences on the basis of distinct sets of processing operations applied
in culturally meaningful activities (linguistic, logico-mathematical, musical, spatial, bodily/kinesthetic, interpersonal,
intrapersonal). This theory addressing both of the major flaws, which were present in some of the earlier, tests. Nonetheless,
Gardner?s theory is just that a theory, it is not rooted in strong empirical data. However, I believe that this is, to date, the best
theory of intelligence that has been developed. Nature or Nurture? Gardner proposes that there are seven distinct types of
human intelligence patterns, which manifest themselves to varying degrees in each of us. This might begin to account for the
infinite variations in human abilities. There could possibly be more than just seven but even five types, for example, of
intelligences could be mixed in varying degrees to produce the diversity of human existences throughout the ages. However this
does not speak to the origins of intelligence. Is the type and degree of intelligence that we possess a product of our genes or
does our environment determine it? A more sensible question might be to ask which, nature or nurture, is in the driver?s seat?
Researchers have been trying to design experiments to investigate this very question for at least a century. The most common
type of study has been one, which investigate the intelligence in identical twins reared apart. This should allow the researcher to
differentiate between the effects of nature and nurture on intelligence. The results have given us estimates as high as 70% for the
attribution of genetic influence on intelligence variance(Ken Richardson, Understanding Intelligence). Although these results
seem to be conclusive evidence for the view that intelligence is primarily genetic it is not without its critics. It is fairly rare for
identical twins to be reared apart, therefore producing small sample size and thus results that can not easily be generalized. The
environments that separated twins are brought up in are likely to be similar, making it difficult to accurately attribute variations in
intelligence to their genetic makeup. The most common criticism of all such studies is the very measurement of intelligence.
Without an accepted definition, intelligence can not be accurately measured and thus trying to understand its development is
somewhat futile. There are so many factors that contribute to human intelligence and development that trying to find causal links
is an exercise in fantasy rather than a scientific endeavour. For us to understand exactly how intelligence develops would be to
unravel one of the most illusive mysteries facing humankind. I don?t however, believe that this puzzle is likely to be solved in the
near future. Social Deconstruction Whichever determinant one believes to have the greater influence on intelligence, it is
undeniable that the other still plays a part. Therefore, the environment in which we are raised has a direct effect on the type and
the degree of intelligence we may develop, the only ambiguity is how large or small this effect might be. Even if only 30% of the
variation in intelligence is attributable to environmental factors, this effect should still be detectable. Victoria J. Molfese, Lisabeth
F. DiLalla, and Debra Bunce from Southern Illinois University at Carbondale conducted a study, which attempted to measure
the effects of socio-economic status, home environment, and biomedical risk factors on intelligence test scores of 3 to 8 year
olds. Home environment quality was evaluated according to maternal intelligence, characteristics of the home, and parenting
practices. Although the researchers found that home environment was the best predictor of scores on intelligence test scores,
the definition of a superior home environment seems fraught with biases. The conclusion that the researchers draw is a valid one
based on their data but may not easily be generalized. A good home environment is undoubtedly essential to the intellectual
development of young children but what constitute such an environment is certainly open to debate. Differences in values may
lead to incorrect assessment of home environment and thus skew the results. The second measure that they employed, as a
predictor of intelligence test scores, was that of Socio-Economic Status. This is, in my opinion, is a more objective factor. The
results from the study showed that SES had a greater effect on predicting intelligence test scores of 5 to 8 year olds. Many
studies have also shown that early adolescent test scores are positively correlated with SES. These results would seem to
suggest that as children become older and gain an awareness of their SES their intellectual development suffers. This could be
the result of stigmatization, once the individual realized that they do not posses the things that others in their environment do,
they may feel inferior. Conversely their peers might treat them in a negative manner leading to what Goffman termed a ?spoiled
identity?. Because money is often equate with morality, those children who are monetarily disadvantaged might feel and be
made to feel that they are inferior which might affect their self-conception and lead to decreased motivation. It is extremely
difficult to draw any conclusion because of the dynamic relationship of the multitude of environmental factors that work together
to shape intelligence. No links were found between biomedical risk factors, such as preterm and low birthweight babies, and
intelligence test scores. This study shows a link between SES and the development of a pattern of intelligence, which is tested
through conventional IQ tests. It is hard to generalize these results to other types of intellectual patterns such as those in
Gardner?s model. However, if SES affects IQ through the process of stigmatization than there seems to be no reason why it
should not affect the development of other types of intellectual patterns such as interpersonal and intrapersonal intelligence. We
have all experienced the negative effects that stigmatization can have so it isn?t hard to imagine that being stigmatize due to a
factor which is enduring and beyond one?s control could potentially have profound effects. A study conducted by Steve Henry,
Ph.D. Gen. Dir. Planning, Eval. & Grant Procurement, looked at the correlation between ethnicity and SES and achievement
on a standardized test for 4000 students in grades 3, 5, 8, and 11. The findings showed that ethnicity accounted for 6.5% of
the variability in scores while SES accounted for 15.9%. There was also a strong link between SES and ethnicity. White
students were twice as likely to come from a higher SES bracket than were minorities. This study again suggests that a low SES
is a strong predictor of success on standardized achievement tests. It also points to the fact that ethnicity by itself is not a good
predictor of achievement. This is in line with mountains of evidence gathered over the last two decades which debunk the myth
that race is correlated with intelligence. The horrors of World War II awoke the world to the reality that associating inferiority
with a particular ?race? can have dire consequences. More recent sociological investigations have questioned the entire notion
of race. Race can be seen as a way of classifying a group of people based on physical traits that have been given a social
meaning. It is a social construction used to maintain a hierarchy, which favours the dominant ?race?. Having darker skin does
not correlate with lower intellectual abilities but does correlate with lower socio-economic status. As we have seen low SES
also correlates with ethnicity. It would suggest that the mere belief the visible minorities are intellectually inferior puts them at a
socio-economic disadvantage, which leads to poorer intellectual development. In order to properly assess the variance in
intelligence across humanity, we must first strip away some of the widely held myths about social groupings. It is extremely
important to examine and deconstruct the social meaning behind existing groupings such as race, gender, and sexuality before
we can properly asses what environmental factors contribute to the formation of human intelligence. Intelligence as a privilege
There is no doubt that the people who demonstrate greater intellectual ability are accorded more freedoms and privileges in our
World. As I have iterated intelligence is not a value-neutral concept and is subject to social construction. The first of these
constructions is that particular types of intelligence are more valuable to human evolution. Scientist who posses high level of,
what Gardner termed, logico-mathematical intelligence are accorded greater prestige while social workers who demonstrate
high levels of interpersonal intelligence are given less. The social construction of intelligence can warp our perception of the
usefulness of certain types of knowledge. It is my opinion that various patterns of intelligence should be accorded equal
importance to ensure that human intelligence is allowed to evolve in all of its diverse manifestations. However, this type of social
construction of intelligence transcends all other social constructs. That is that all ?races?, for example, should demonstrate an
equal distribution of all the patterns of intelligence. The current conceptions of what types of intelligence are most desirable can
not be attributed to socially constructed groups such as race or gender. Therefore we are all subject to equal discrimination
based on the type of intelligence in which we demonstrate the greatest aptitude. However, as I have already mentioned, the
mere belief that a group is endowed with particular patterns of intelligence can influence development. The second dimension of
intelligence that endows privileges is that of degree. Without relying on conventional IQ test to show that humans differ in levels
of intelligence, it seems that life experience has taught us that we are not all as ?intelligent? regardless of what type of intelligence
we are referring to. Some of the variance can be attributed to micro and macro environmental factors but for evolution to work
