A study by Robert Waldmann and his colleagues found that there was no significant relationship between intelligence and job performance, even at a college level. Intelligence scores were not a good predictor of future job performance if we were to choose between a person with a high IQ score and one with an average IQ score. However, college graduates are generally more intelligent than high school graduates. That said, there is a strong relationship between college attendance and IQ scores. The study goes on to say that college graduates who completed a bachelor’s degree have a significantly higher IQ score than do individuals with only a high school diploma.
The last part of the study says that it’s worth noting that the study does not test how intelligence relates to job performance in the labor market. It can’t really say whether people with high IQ scores have a better chance of landing a high paying job than do people with lower IQ scores. What it does tell us, though, is that people with high IQ scores tend to perform better in academic environments that demand more intellectual tasks.
If you‘re looking for a university-level examination, you should do a little bit of research on your own. One thing to remember is that correlation doesn’t always equate to causation. It’s true that you might get a higher grade if you take a class or book you love and apply it to your final exam, but there may be many other factors that can influence your grade. For example, if a teacher gave you the assignment but told you what you needed to study in class, the test will reflect that.
If you don’t get a college degree, you should still keep your eyes open. A higher IQ score might be correlated with a better chance of getting a job, but you may be much more likely to land the job if you already have a college education.
A study by Joseph Parent and James Truslow showed that college students who did poorly on standardized tests in the United States were more likely to have problems in school after getting their high school diplomas. The study also showed that college graduates in the bottom 25% of the income distribution had higher chances of having problems. After controlling for socioeconomic status, the study concludes that a higher IQ score indicates higher chances of earning more money after graduation.
High school diploma is the most important factor when it comes to predicting salary, but high school education is not the only factor important. High school graduates who perform well on standardized tests tend to do well in college and earn a better income.
While correlation does not prove that high school education is the best indicator of financial success, it’s worth keeping in mind that it does seem to indicate that those who have a higher IQ score are more likely to have a good job, a higher chance of being promoted within the company, and a better chance of securing a job promotion. And for the more academic minded: Those who have a college education are more likely to obtain a job in a field related to the one they attended high school for.
