An example of intelligence quotient, or IQ, is a standard measure of human intelligence by the score of cognitive tasks. IQ isn't the be-all and end-all of the human mind, but it is a major predictor of academic and professional achievement. To understand why IQ is important we must see what its importance in education, employment, health, and societal contribution is.

Educational Achievement

This academic performance is very closely linked to IQ scores. Studies have shown that kids with higher IQs can better assimilate, and remember, information and thus perform better on their grades, and understand subjects better. According to the American Psychological Association, though, children with a high IQ score tend to learn more than their lower-scoring classmates of what is taught in school.

This said, however, IQ is not the only factor contributing to an individual’s academic success. Also important are factors like motivation, the subject’s interest, and study habits. Despite this, IQ is essential to instructing a teacher to know what he has to teach and what he needs to teach.

Professional Success

IQ is a good predictor of job performance in the workplace, so much so that when you have to do something with complexity and problem solving, and with critical thinking, that is very predictive. Research indicates that scores of IQ correlate with job performance ratings in a variety of occupations. According to Schmidt and Hunter, for example, research shows that general mental ability is an excellent predictor of future job performance.

Yet, the relationship between job performance and IQ is not one. Other factors matter like emotional intelligence, interpersonal skills, and work ethic hugely impact a person’s success he establishes in his profession. As such, IQ is a good measure of someone’s potential, but taken alone says nothing about performance overall.

Health and Longevity

Research is emerging that shows that higher IQ may be tied to better health outcomes. Studies done in Scotland have shown that people with higher IQs in their youth are linked with a better chance of survival later in life.

This correlation is complex and varied in origin. People with higher IQs may have more access to health care, healthier lifestyles, and better health literacy – meaning they have more understanding of healthy practices – and know more about how they can stay healthy. Furthermore, cognitive abilities may play a role in being able to manage stress and negotiate other challenges to health.

Societal Contributions

At a higher magnitude, populations with a higher average IQ are also associated with socio-economic benefits such as economic development and technological innovation. Those who are intelligent are often behind the basic science, the tech, and the arts, and often help advance us as a society and enrich the world around us.

But, of course, it's necessary to handle this issue with trepidation. All these and many other factors make for societal success. IQ can play a role, but it is not the be-all and end-all of prosperity, or of cultural achievements in a society.

Limitations and Considerations

IQ may be a great tool for assessing these particular cognitive abilities but there are limitations. It does not factor in creativity, emotional intelligence, practical skills, or any other variety of intelligence that you need to be a successful human being. Additionally, IQ scores can be affected by a number of factors such as socioeconomic status, schooling opportunities, and cultural biases embedded in certain testing methods.

In other words, while IQ offers useful information about only one aspect of cognitive ability (basic mental processes) it should be analyzed in light of other factors (emotional intelligence, creativity, etc.), and as just one factor in determining an agent’s general intellectual ability.

Conclusion

In short, IQ is an excellent predictor of cognitive abilities contributing to educational success, occupational performance, health, and measures of social contribution. But it’s not all criteria to determine the potential or worth of a person. Accepting the many layers of intelligence and what constitutes success is key to understanding the part IQ plays in endowment.

However, IQ tests also show you that it’s only a snapshot into your intellectual capacity and that no two people have the same strengths – they can’t all be measured by a standardized test. By adopting a more holistic approach for determining human potential (emotional intelligence, creativity, practical problem solving skills etc) we can make our society more inclusive towards how intelligence and eventual success is determined.
