IQ testing has numerous applications. For example: * SAT tests largely amount to IQ tests and are used extensively for college admissions in the US. College degrees from top US universities remain the most sought after degrees in the world. * Magnet schools in urban areas regularly utilize IQ tests or their equivalents to elevate students into advanced coursework. This enables students to rise above their socioeconomic status. * European secondary schools regularly use tests that correlate with IQ tests to track students into programs leading to universities versus technical schools. These tests help coordinate society and deploy human capital where it is most needed. * Even the US military uses IQ tests to avoid accepting recruits who don't meet a certain standard. This aids in ensuring the security of western nations. IQ testing could be used in additional areas, such as: * Encouraging higher IQ parents to have more children through subsidies, thereby increasing the likelihood of future technological innovations assisting all mankind. * Assisting in identifying individuals who need more support from society. * Better understanding the causes behind social ills like poverty, drug addiction, homelessness and the like. Understanding that an individual's IQ is a stronger determinant of economic outcome than other variables, such as race, is a step toward a society with more solidarity and less friction. I appreciate that you have a bias against intelligence testing, and I understand its genesis (your mention of the "eugenics craze" makes that clear). I'm suggesting society aim toward an enlightened view of these things where people's IQs don't identify them as "greater" or "lesser". Wishing IQ away is unlikely to work, particularly in a world about to experience the arrival of super-intelligent AI systems.
