The first ever intelligence test (Binet-Simon) was designed partly in order to identify children who have intellectual disability and give a better treatment for them. The test itself was crude, but I believe that should be the only meaningful use of IQ tests because overly low or high IQ does predict certain kinds of complications. Otherwise they are easy to game, they only measure a particular slice of human intelligence, and their error bar is large enough that even a unit difference in SD can be not meaningful [1]. IQ is just a meaningless number that whoever have a higher one tends to have unjustified superiority over others. [1] Depends on the particular test of course, but I can safely guess that +2 SD and +2.5 SD are not statistically distinguished by most tests. |
