The term emerged in the late 19th century, pioneered by figures like Francis Galton and Karl Pearson, who sought to quantify human abilities. Its development coincided with the rise of statistical methods and the desire to bring scientific rigor to psychology. Early applications focused on measuring intelligence and individual differences.
