Intelligence as we all know, is the key factor for preforming most of society's learning and daily functioning. However, if someone were to merely ask “What is Intelligence?” could most American's give an accurate answer? The definition for intelligence has long been a term of context for many decades with no individual really understanding the true meaning behind it. Many studies have been conducted to form the conclusion that intelligence encompasses three different sub-sets of Intelligence: I.Q., E.Q., and personality. One of the earliest people to study the literal measurement of an individual's intelligence was British psychologist Sir Francis Galton. Galton's early studies in hereditary improvement led him to believe that intelligence was something that was inherited and could not be changed. He was convinced that by selective parenthood he could create genius' at will, this theory came to be known as “Eugenics.” According to Galton's Eugenics intelligence encompassed things such as reaction time, eyesight, cognitive ability, etc (Psychology History). However, early studies failed to show any validity to Galton's findings and soon enough they fell out of favor. (What is Psychology? p.287) In the decades after Galton's research many psychologist's began to focus heavily on the cognitive aspects of intelligence instead of trying to link it with physical functions such as reaction time and eyesight. During this period researchers nearly debunked Galton's belief that intelligence was mostly heritage. These researchers began publishing tests that could accurately measure a individual's intelligence with a series of critical thinking questions. Among these was Alfred Binet, who was the pioneer in developing such tests and is now known as the father of the modern I.Q. Test (What is Psychology? p.287). Binet's research gave the field of Psychology its first
