Asked about reports that Secretary of State Rex Tillerson called him a "moron," President Donald Trump told Forbes, “I think it's fake news. But if he did that, I guess we'll have to compare IQ tests. And I can tell you who is going to win."
Well, in case there are questions about IQ tests on IQ tests (there are not), here are a couple of facts about the Intelligence Quotient… (Bonus Fact: the phrase comes from the German term "Intelligenzquotient")
An IQ is not based on one test, but is a score derived from several standardized tests designed to measure various forms of intelligence, both verbal and non-verbal.
One of the more popular tests – the Wechsler Adult Intelligence Scale (WAIS) and Wechsler Intelligence Scale for Children (WISC) – generates a "Full Scale IQ" based on four indexes: Verbal Comprehension Index, Perceptual Reasoning Index, Working Memory Index, Processing Speed Index. The WISC also includes the Fluid Reasoning Index.
Here are some examples of tests and what they measure:
Participants are given two words and have to explain how they relate (abstract verbal reason)
Participants put together red-and-white blocks in a pattern according to a displayed model (visual spatial processing, visual motor construction)
Participants are asked to define certain words and answer math problems (semantic knowledge, quantitative reasoning)
And still more facts...
IQ scores are often used for education placement (special-ed, gifted) and assessing intellectual disabilities.
The IQ test has been criticized in the past for cultural and ethnic biases. Critics also argue that an IQ score says little about creative, artistic, emotional, or putting-together-listicles-for-an-app skills.
Sorry: brain games like Lumosity will not make you smarter. However, studies have found a few ways to increase overall cognitive functioning:** seek novelty; challenge yourself; think creatively; do things the hard way; network**.
IQ tests were also used by the army during World War I. Wondering how’d you do on that 1918 test? You’re in luck—we’re reprinting it below.
How to score the Devens Test:
Subtract the number of wrong answers (or questions you can’t answer) from the correct answers. Score below 6: Illiterate; 6-20: Primary literacy; 21-25: Grammar school literacy; 26-30: Junior high school; 31-35: Senior high school; 36-42: College level.
