Academic performance in school is one area that IQ levels can accurately predict. According to research, those with high intellect are also more effective at work. They tend to rise to the top of their fields, becoming leaders who earn higher salaries and advance further in their careers. On the other hand, those with low IQ scores rarely make it past the lower ranks of any profession.
Intelligence tests have been used for over 100 years to identify children who need special education. Because these tests are based on how well individuals perform certain tasks, they can also be used to measure an individual's current intelligence level. The results of these tests are often used by teachers to help those who score low-average or below average develop their skills through training or assistance from professional psychologists.
The IQ test is just one of many ways you can estimate someone's intelligence. You could also look at how well they do in school, what career they choose, etc. There are even studies showing that people can be identified by the types of friends they keep, the neighborhoods they live in, even the television shows they watch!
In conclusion, intelligence is a factor that predicts future academic performance and workplace success. It is not the only factor but it does play a role.
Indeed, the relationship between IQ scores and work success is frequently mentioned as supporting the validity of IQ examinations. "The statistics are unequivocal: [measured cognitive capacity] is the most strong individual difference feature that predicts work success," write Ones, Viswesvaran, and Dilchert (2005).
IQ tests have been used to select employees for jobs where high levels of intelligence are needed (such as military officer training programs) or to exclude individuals from those jobs (e.g., hiring managers in Silicon Valley who want to be sure that no one is stupid enough to try to build a computer chip factory on site).
There is also evidence that shows that people who have higher IQ scores are more likely to rise through the ranks to higher paying jobs. One study conducted by the Federal Reserve Bank of St. Louis found that male workers with higher IQ scores were more likely than others to be promoted into management positions. It's possible that these men were selected for their jobs due to their intelligence rather than because they worked the least hard or had connections that allowed them to climb the ladder faster. However, another study conducted by Edward Thorndike at Columbia University found that female employees with higher IQ scores were more likely to be given raises and promotions than others.
In conclusion, there is evidence that shows that people who have higher IQ scores are better able to succeed in occupations requiring high levels of intelligence such as science, technology, and math.
IQ levels cannot account for all types of achievement. In fact, even a single form of success is difficult to completely and correctly quantify using IQ ratings. While there is some association between IQ and financial or professional success, even these categories are wide and general. For example, someone with an IQ of 160 could be a high-powered executive or could be a janitor.
The best predictor of future behavior changes not only mental abilities but also interests, values, and goals. These personal factors are much more important in determining how well someone will adjust to new circumstances and succeed in school or work. The correlation between IQ test scores and success in life is very low.
You might have a high IQ but be uneducated and illiterate. You can have a degree while having a lower IQ. IQ exams assess your capacity to think, comprehend concepts, and solve problems. In that regard, intelligence may be a question of inheritance and potential. Some people are born with an innate ability to learn fast or adapt well to new situations. These individuals appear smart even if they don't have much knowledge about many topics.
People with high IQs may not know it themselves. They may assume that since they can understand difficult concepts quickly there is no way they could be confused by them. This can lead to them trying problems that are beyond their abilities which may cause them to give up.
It's possible for someone who appears bright but isn't educated or trained in the right ways to use their intelligence. For example, a genius mathematician may spend all their time alone in their room thinking about math instead of going out and meeting other people who could help them with their work. If this person was never taught how to take tests or analyze data accurately, they might end up with a high IQ but fail academia.
Intelligence is also related to memory and processing speed. A person with a high IQ can store more information in their brain than others so they can retain more facts and ideas over time.
