How does IQ test actually work?
In: Biology
Alright, a lot of good explanations, but not a lot of “explaining like I’m 5”. The most popular IQ test is the WISC V. Usually, these tests are conducted in a 1 on 1 setting over the course of about 1-2 hours. There are multiple subtests which measure “intelligence” in 5 different ways. Visual Spatial (Ex. manipulating blocks to match a pattern), Processing Speed (Ex. Figure out a code with a symbol key), Verbal Comprehension (Ex. Vocab knowledge) Fluid Reasoning (Deductive reasoning skills), and Working Memory (Remembering numbers). Based on your score from all the subtests, you “add” them all up to make a Full Scale IQ. Full Scales IQ’s have an average of 100 and a standard deviation of 15. Meaning that most of the population lies between a score of 85 and 115. Like many people have said, an IQ test is not a representation of someones complete intelligence. For instance, someone could be a complete genius in painting or music, and the IQ test would never pick that up. However, the IQ test does measure abilities that are correlated with being able to navigate the modern world with success.
