Spearman believed that intelligence can in fact be measured. He helped develop a procedure called “factory analysis” that “enables researchers to identify clusters of test items that measure a common ability” (Myers 432). In doing so, Spearman was able to study people and come to the conclusion that those who get a high score in one test, typically, score high on average on other tests. He called this commonality the “g factor”, which is an indication of someone’s intelligence. Spearman’s idea that intelligence can be measured through various tests caused some controversy because some believed that tests cannot determine how intelligent or unintelligent a person is. One person who had a different idea of intelligence than that of Spearman’s was L.L. Thurstone. His theory focused on seven different “primary mental abilities,” they include verbal comprehension, reasoning, perceptual speed, numerical ability, word fluency, associative memory, and spatial visualization (psychology.about.com).

They found out that people who scored higher on emotional intelligence tests were overall much happier those who did not. “In both the United states and Germany, those scoring high on managing emotions enjoy higher-quality interactions with friends of both sexes” (Myers 437). They are able to lead productive lives, avoid falling into depression, and often give good
