Research has found that those school districts which have implemented screening measures for all children using IQ tests have been able to identify more children from historically underrepresented groups to go into gifted education.
Their findings, reported in Neuron, are a result of the data provided bypeople of various ages and cultures who completed 12 cognitive tests. Army Alpha and Beta test results garnered widespread publicity and were analyzed by Carl Brighama Princeton University psychologist and early founder of psychometrics, in a book A Study of American Intelligence.
To address the issue, he called for social policies to restrict immigration and prohibit racial mixing. The application of the same test among different communities would fail to recognize the different cultural values that shape what each community values as intelligent behavior. Thanks for watching!
Bell were disproportionately poor or of color. Taking into account the full range of cognitive abilities tested, they found that people's varying success rates could only be explained by combining at least three types of intelligence, and not by any single measure such as IQ.
The use of IQ tests in a range of settings, and the continued disagreement over their validity and even morality, highlights not only the immense value society places on intelligence—but also our desire to understand and measure it.
