How Effective are Intelligence Tests in Predicting Performance of Individuals.
The effectiveness of the intelligence tests depends upon the knowledge, skill and integrity of the user. Example: intelligence tests can be applied in the real world to predict success in job or at school or in society.
Example: children scoring well on these tests are very likely to perform well at school and achieve good grades.
At work, the tests have considerably less effectiveness in predicting the work performance but high scorers tend to get high paying and more prestigious jobs than the low scorers. General intelligence tests have about 25% effectiveness in predicting overall job success because usually job success depends more upon motivation, education. The correlations between IQ and academic achievements as well as occupational success do exist but other factors also contribute to success in school and work, those factors maybe motivation, physical and mental health, social skills, parenthood.
The longer people work at job and the more experienced the get the better they become and the correlations of IQ and achievement decrease. The single IQ number can be easily lead to false expectations. People also tend to form generalizations on the basis of an IQ score, leading to false expectations.
Example: A student gets a low score an IQ test and the teacher that day onwards thinks it is useless to spend much time with him and ignores him to prefer the high scoring ones these tests do have limitations but are widely used in schools, colleges and professional environments, to be effective they must be used along with other information about an individual.
Example: IQ test should not be the only determinant and is usually not because we see interviews medical test, psychological tests being taken in professional environment besides written tests.
We do not have many alternatives to intelligence tests but discriminatory practices initiated on the basis of intelligence tests performance are unethical and must be avoid rather, the tests should be used to know a child’s strengths and weaknesses to draw up his cognitive profile so that to help him through appropriate remedial programmers IQ tests tap only a part of human’s overall competence. It is not the ultimate human value.
Example: Robert Sternberg proposed the triarchic theory of intelligence but himself got very poor results on the intelligence tests in his school. The intelligence tests are based in favor of the upper and upper-middle class of population they easily belonging to lower classes and never compare the positive aspects of lower children with the upper class ones. Some people also have difficulty understanding the language of the test perilous experience could affect the ability of a person to answer correctly if there is a question or two in the test.
