Intelligence testing was first used to back in the early 1900s among children to see who was not at the same level as their peers, but today much of that has changed. It has evolved from only testing children to now testing adults too. Its measurement allows people to see the level of their intelligence. One of the main groups that the testing has helped the most is the U.S. Military.
The downside though is that many people agree that there are many biases to the intelligence tests. According to the article the test has "been accused of unfairly stratifying test-takers by race, gender, class and culture; of minimizing the importance of creativity, character and practical know-how; and of propagating the idea that people are born with an unchangeable endowment of intellectual potential that determines their success in life" (Benson). Many researchers have tried to change the test to make it fair, while still trying to keep the usefulness of it. They have changed up the tests for diverse groups and people of different linguistic abilities by improving Stanford-Binet system and Wechsler Intelligence Scale for Children. This has allowed many of the biases on the tests to decrease.
The test has always been questioned because of the differences every test taker brings to it. I believe that there will always be biases to the test. Not everyone will agree with their score and everyones score will fluctuate at various times. Many people have their opinions on whether IQ tests should be given or not given. According to APA President-elect Diane Halpern, '"We're not all the same; we have different skills and abilities. What's wrong is thinking of intelligence as a fixed, innate ability, instead of something that develops in a context"' (Benson). I agree with this that everyone is different and unique in some way and were all changing. Intelligence testing shows how intelligent you are at that point in time, but when you take it again later your score is somewhat likely to be different. At the end of the day, IQ tests will change, but will there be a perfect IQ test, it is unknown.
