As scientists continue to their research, fundamental questions about intelligence are brought to the surface.

Ever since Spearman proposed the intelligence theory with G factor, there were several other intelligence theories proposed in response or as an alternative to Spearman’s. Among those, Sternberg’s Triarchic Theory of Intelligence and Gardner’s Multiple Intelligence Theory would be the most influential ones as they are widely accepted and used in real life. Both of the theories share a critical view towards the unitary perspective which is the traditional definition of intelligence. However, the two theories differ in which they don’t agree with what factors should be the measures of intelligence, as well as the emphasis of the two theories.

In “A Rounded Version: The Theory of Multiple Intelligences”, Howard Gardner illustrates how there are a variety of intelligences. Gardner starts off with an example how IQ tests may predict achievement in school but may not predict achievement in life. After finding out certain parts of the brain are responsible for certain functions, such as “Broca’s Area” which is responsible for sentence production, Gardner proposes the existence of multiple intelligences. Multiple studies later led him to propose seven distinct intelligences; Musical, bodily-kinesthetic, logical-mathematical, linguistic, spatial, interpersonal, and intrapersonal. Each intelligence has certain classifications. According to Gardner’s classifications, I realized my intelligences are bodily-kinesthetic, logical-mathematical, and intrapersonal.

Charles Spearman's model of intelligence and Howard Gardner's multiple intelligence theory are two of the most widely used theories of intelligence. In order to understand how similar the two theories are we must first understand their differences. These two men differed in opinion on how IQ and intelligence should be measured, and they differed in opinion on what made a person "smart". In order to examine these things they first had to understand the human brain and how it works. They had to examine the human study habits and rituals, along with the human test taking habits.

On the contrary, those people who scored low on one kinds of ability test, were more likely to score badly on others as well. Meanwhile, Spearman also concluded that intelligence is a cognitive ability which could be measured and expressed numerically.

Intelligence is an interesting concept and whilst we understand and can agree that it is what differentiates us from other all the other animals it is almost impossible to agree exactly how to measure it.

Charles Spearman’s theory (1904) also takes the psychometric approach that there is a general intelligence. Spearman maintains that intelligence is hereditary and an individual is born with their maximum mental ability. This suggests that intelligence cannot be changed or strengthened. The concept of ‘general intelligence’ suggests that an individual has an underlying intelligence, in which their performance in one type of cognitive task is often similar to their performance in another (Boundless 2013). Spearman demonstrated this through the correlations between tests, where individuals who performed well in one test, often performed well in others. This led Spearman to the conclusion that intelligence is defined as a single factor. However, critics refute Spearman’s conclusions, as they argue that one cannot reduce all factors of intelligence to an indefinable “g” (Neisser et al. 1996).

Human intelligence is one of the most complex and abstract things in the world, but because of one test created by Lewis Terman, a professor of psychology at Stanford University, we are able to see it as a small, simple number (Epstein, 1973). An Intelligence Quotient (IQ) Test scores human intelligence on a numerical scale. Within this scale there are several categories which people are placed in as shown in Table 1. These scores, categories, labels, are tidy, easy to remember, and can greatly influence one’s life. They can act almost like a name tag, and become an identifying factor wherever you go.

How is intelligence measured? How is it possible to just have one way to measure intelligence? Is there really only one way to measure every individual’s intelligence? According to psychologists Howard Gardner and Robert Sternberg there is. Gardner and Sternberg have developed two different theories to do so. Howard Gardner’s theory of intelligence is the way in which one carries out life goals. Gardner chose eight abilities that held to meet criteria: linguistic (speak and write well), logical-mathematical (use logical and mathematical skills to solve problems such as scientific quotations), spatial (think and reason about objects in three dimensional space), musical (preform, understand and enjoy music), bodily-kinesthetic (manipulate

There is a relationship between intelligence and culture because intelligence is culturally shaped and defined and some cultures support and identify it as very vital in the context of social and ecological aspects. In the early years, there was a bias towards intelligence tests because they used English language and culture. The formation of Wesler Adult Intelligence Scale, Fourth Addition (WAIS,IV) in 2008 by David Wesler was meant to minimise the bias. According to Westen, Burton and Kowalski (2006), intelligence assists human beings to take control of their lives and it varies cross culturally because the power dynamics differ in each society and this leads to differences in behaviour and line of thinking. These authors describe intelligence as multifaceted, functional and can be defined by culture because it is universal and studying intelligence using different culture as a sample that can be used to question Western ideas about intelligence with some emphasis on the assessment of skills and abilities using culturally appropriate methods (Benson, 2003)

Intelligence tests even in these days remain somewhat controversial, from its interpretations, to their classifications in scoring on bell curves. So is the magnitude of debate, that many professionals in assessments question the value of these tests. One aspect of much controversy is the use of a single or multiple scores to determine intelligence. Some general intelligence assessments only use a score, g. This apparently reflects the variance underlying shared in different series of tests performance. Nevertheless, recent theories have suggested that human intelligence can be better measured in terms of multiple types of intelligence rather than a single score. One of those theories is the gf-gc; this theory indicates that there are two types of intelligence: f = fluid and c = crystalized.

The theory of multiple intelligences was developed by Dr. Howard Gardner in 1983. The Theory of Multiple Intelligences is a critique of the standard psychological view of intellect: there is a single intelligence, adequately measured by IQ or other short answer tests. Instead, on the basis of evidence from disparate sources, the theory claims that human beings have a number of relatively discrete intellectual capacities. IQ tests assess linguistic and logical-mathematical intelligence, and sometimes spatial intelligence; they are a reasonably good predictor of who will do well in school. This is because humans have several other significant intellectual capacities (Harvard University).

Discuss epistemology and its relevance to intelligence analysis. Select at least two principal “ways of knowing,” and describe their respective characteristics/attributes, strengths, weaknesses, and potential for improving the quality of intelligence analysis.

When a person utters the word “intelligence,” people tend to think of a genius like Albert Einstein developing some obscure equation that the great majority of the population will never understand. The problem with the definition of intelligence is that people relate intelligence to words like “genius” which require intelligence but do not have the same definition as intelligence. Often, people try to use related words to define intelligence, but these words are unable to define intelligence since many are only different levels of intelligence. While many definitions try to encompass the meaning of intelligence and various definitions describe a small part of intelligence, no definition completely explains intelligence, because
