What is wrong with IQ tests? – THE SCIENCE BAY

many of you have probably heard of intelligent quotient also known as iq tests first created more than a century ago the tests are still widely used today to measure an individual’s mental agility and ability the tests claim to measure intelligence but does it really show how smart you are and could we trust the results let’s find out it all started more than a century ago in france in the early 1900s dozens of intelligence tests were developed in europe and america claiming to offer unbiased ways to measure the person’s cognitive ability the first of these tests was developed by french psychologist alfred binet who was commissioned by the french government to identify students who would face the most difficulty in school the resulting 1905 binay simon scale became the basis for modern iq testing ironically binet actually thought that iq tests were inadequate measures for intelligence pointing to the test’s inability to properly measure creativity or emotional intelligence during world war 1 the army needed a way to evaluate and assign recruits to appropriate tasks this led to the development of several mental tests by robert yorkis 1.75 million men were tested in total making the results the first mass-produced written tests of intelligence after the war positive publicity promoted by army psychologists helped to make psychology a respected field intelligence tests were developed and became widely used in schools and industry since the early 20th century ros scores on iq tests have increased in most part of the world the phenomenon of verizon or score performance was named the flint effect after james r flynn the author who did the most to bring this phenomenon to the attention of psychologists while iq tests are generally considered to measure some forms of intelligence they may fail to serve as an accurate measure of broader definition of human intelligence inclusive of creativity and social intelligence for this reason psychologist wayne whitton argued that their construct validity must be carefully qualified and not be overstated according to written iq tests are valid measures of the kinds of intelligence necessary to do well in academic work but if the purpose is to assess intelligence in a broader sense the validity of iq tests is questionable some scientists have disputed the value of iq as a measure of intelligence altogether in the book the mismatcher of man 1981 evolutionary biologist stephen j gold compared iq testing with the non-discredited practice of determining intelligence via craniometry argument that both are based on the fallacy of verification our tendency to convert abstract concepts into entities at the same time one u.s study in 1995 used iq tests to look at the effectiveness of a particular type of training for managing attention deficit hyperactivity disorder adhd the researchers used iq tests to find out whether the training was effective in improving the concentration and executive functioning of children with adhd the use of iq tests in a range of settings and the continuing disagreement over their validity and even morality highlights not only the immense values society places on intelligence but also our desire to understand and measure it the idea that intelligence can be measured by iq tests alone is a fallacy according to the largest single study into human cognition which found that it comprises of at least three distinct mental traits short-term memory reasoning and verbal component iq tests can be useful as a part of an overall assessment of the whole person scores from intelligence tests are estimates of intelligence unlike for instance distance or mass a concrete measure of intelligence cannot be achieved given the abstract nature of the concept of intelligence so even if iq tests are not ideal have some biases and do not really measure your intelligence but only solve cognitive abilities they still could be used for good and be useful to get some more information about ourselves the way we think our perception and reasoning and that’s been it thank you for watching this video if you find it interesting and useful smash it like subscribe to this channel for more videos ring the bell and i will see you next episode bye bye
