His work is further shadowed by his early involvement with and promotion of the eugenics movement (Fallace, 2016; Jolly & Warne, 2019; Warne, 2019), although as he became older and Terman’s support for eugenics lessened (Warne, 2019). On the contrary, various scholars have provided evidence for the empirical robustness of intelligence research in the heritability of IQ or general intelligence (Plomin et al, 2016; Polderman et al, 2015); its ability to predict various positive life outcomes, including occupational, academic, health, and socioeconomic (Brown et al, 2020; Lubinski & Benbow, 2021; Strenze, 2007); and its long-term stability (Deary, 2014; Deary et al, 2013) even from infancy (Yu et al, 2018).…”
