One important concept in Psychology is the invention of the IQ test, a diagnostic tool designed to measure overall thinking ability. The first intelligence test was created in 1905 by Alfred Binet and Théophile Simon to determine which French school children were too slow to follow "regular" instruction by teachers. In discussion a few weeks ago, we discussed if IQ tests should be used solely to hire applicants for certain positions. I feel that intelligence tests should not be used in any way to choose one candidate from another. Although the correlation between job performance and interviews is only +0.15, IQ tests should not be used to fill that gap because Intelligence tests have many downfalls. For example, they cannot be applied to the general public, specifically those who do not speak the language that the test is in. If the test is in a language that is not native to the speaker, then it will inevitably be more difficult for them, regardless of how the test is written. Furthermore, intelligence tests evaluate how smart one is, but does not test how they process information, or their critical thinking skills. The way someone process information and think critically is extremely important in any job, but that is not assessed through an intelligence test. Also, IQ tests cannot account for other factors such as job performance, social ability etc, factors that are necessary in any type of job. Also, SATs and Acts are types of IQ tests that are supposed to forecast the performance in undergraduate courses. Yet the correlation between these tests and college grades are less than .5, and in some cases, close to zero. If SATs and Acts are poor predictors of academic performance, similarly, IQ tests will be poor predictors of job performance.
Should you be Hired or Fired because of your IQ Score?
