What’s the difference between intelligence (IQ) and Emotional intelligence (EQ)?

Intelligence is perceived differently by different people, but perhaps the most widely accepted definition is one articulated by psychologist Linda Gottfredson:

Intelligence is a very general mental capability that, among other things, involves the ability to reason, plan, solve problems, think abstractly, comprehend complex ideas, learn quickly, and learn from experience. It is not merely book-learning, a narrow academic skill, or test-taking smarts. Rather, it reflects a broader and deeper capability for comprehending our surroundings, “catching on,” “making sense” of things, or “figuring out” what to do.

Intelligence, denoted to as g is usually measured by IQ tests that score performance on cognitive skills such as those mentioned in the definition above.

However, it is observed that some people of high general intelligence are socially inept or have difficulty relating on a social level to people of average intelligence. Conversely, some people of average IQ have remarkable social skills and seem to have an intuitive understanding of people and how to build social relationships. This latter ability or skill is often referred to as “social intelligence,” or “emotional intelligence.”

(In Arthur Miller’s celebrated play Death of a Salesman (1949) Willy Loman, the main character expresses what would become a popularly accepted measure of success and the social skills required to achieve that goal:

The man [Willy’s brother Ben] knew what he wanted and went out and got it! Walked into a jungle and comes out, the age of 21, and he’s rich! … The man who makes an appearance in the business world, the man who creates personal interest, is the man who gets ahead. Be liked and you will never want.

In the decades that followed, a series of plays and books emerged, promoting the idea that social skills count more than brains for success in the workplace. Today, many believe that success in business and industry is more closely connected to our so-called interpersonal skills than to our IQ. To measure social intelligence, some psychologists developed the concept of emotional intelligenceEmotional intelligence(EI or EQ) as defined by researchers Mayer and Salovey, is “the ability to monitor one’s own and others’ feelings and emotions, to discriminate among them, and to use this information to guide one’s thinking and actions.”

The concept of emotional intelligence had its roots in the work of Harvard psychologist Howard Gardner, who objected to the use of IQ as a single measure of intelligence, arguing that it excludes other cognitive abilities such as innate social skills, athletic potential, and musical ability that contribute to an individual’s success in life. In his seminal book Frames of Mind: The Theory of Multiple Intelligences, published in 1983, Gardner proposed that EQ is, along with IQ, an innate part of intelligence. By the end of the 20th century, the concept of EQ had gathered momentum and in 2000, Dr. Thomas J. Stanley published the results of his survey of 733 millionaires, soliciting their opinions regarding the most important elements in achieving success in business. Among the factors he investigated were “social skills” and “intellectual orientation.” In The Millionaire Mind, he reported his findings:

Far too many of us believe that success is predetermined, a direct result of genetics, and that successful people just have higher IQs than those who are “less successful.” So what if you receive all As in school and near-perfect SATs? So what if your IQ is in the ozone layer of the intelligence scale? Will these factors assure you of a place among the ranks of America’s millionaires?” It’s doubtful if you don’t get along with people. … The large sample of millionaires surveyed were asked about the importance of intellect in explaining their economic success … Only 20% felt that “having a high IQ or superior intellect” was very important … while 56% felt that getting along with people was very important.

By the dawn of the 21st century, the link between people skills and success in America had been forged in the public conscious. Although EQ is vitally important in professions like law, politics and sales, where persuasion is a critical skill, the captains of business and industry in the computer-based occupations place a high premium on IQ.

In 1993, Forbes journalist Richard Karlgaard, in a conversation with Bill Gates asked, “What Microsoft competitor worries you most?” Without hesitation, Gates responded, “Goldman Sachs.” When Karlgaard responded with surprise that Gates named an investment banking company rather than a computer company, Gates clarified:

Software is an IQ business. Microsoft must win the IQ war, or we won’t have a future. I don’t worry about Lotus or IBM, because the smartest guys would rather come to work for Microsoft. Our competitors for IQ are investment banks such as Goldman Sachs and Morgan Stanley.

Indeed, the competition for the best and brightest is a war fiercely waged by the best companies in the hi-tech fields, because these high IQ cognoscenti are the only people capable of pushing innovation to new heights.

Steve Jobs, founder of Microsoft’s major competitor, Apple Inc. explained in an interview with Business Week on October 12, 2004, one of the secrets of his success in hiring employees.

I noticed that the dynamic range between what an average person could accomplish and what the best person could accomplish was 50 or 100 to 1. Given that, you’re well advised to go after the cream of the cream … A small team of A+ players can run circles around a giant team of B and C players.
