Abstract

Measuring innate (genetically determined) mental traits was a major part of the psychometric movement in the early decades of the twentieth century. Low test scores (given as an intelligence quotient, or IQ) were used by eugenicists to lobby in the US Congress for restricting immigration of those claimed to be genetically inferior in IQ.
