Summary
Of all the scientific facts about intelligence research, there is one that I would give anything to change: the existence of average differences in IQ scores across different racial or ethnic groups. These differences appeared in the early days of intelligence testing (e.g., Goodenough, 1926; Morse, 1914; Pressey & Teter, 1919) and have persisted into the twenty-first century (e.g., Carman, Walther, & Bartsch, 2018; Giessman, Gambrell, & Stebbins, 2013; P. L. Roth et al., 2001). Among the most studied racial or ethnic groups, people of East Asian descent usually have the highest average IQ, followed by people of European ancestry.
