IQ in the meritocracy

Abstract

Intelligence, as measured by standardized tests, is largely inherited, with the genes accounting for 70 to 85 percent of the variation between people. The author summarizes a vast body of research spanning decades that consistently show strong correlations between intelligence and various measures of success in school, occupation, and overall life achievement. The author concludes that as society becomes more equitable and opportunities for advancement become more equal, the role of intelligence in determining success will become increasingly dominant, leading to a “meritocracy” where social classes become solidified by inherited differences in ability. As society continues to advance, it will become increasingly important to address the consequences of this biological stratification, including the potential for a growing gap between the intellectually gifted and the rest of the population. – AI-generated abstract
