Reviews and Praise

“The author untangles the cultural, biological, and socio-economic factors at play, the fallacy of selective pressures, the fluidity of racial populations, heritable and nonheritable components, and the crystallized and malleable elements of intelligence….A sturdy, scientifically grounded, and anecdotally engaging study of the factors that shape us.”   -Kirkus Reviews

“ That’s the kind of clarity we need more of in popular science books like this, especially ones that investigate both what makes us human and what makes us distinctly, immutably ourselves.” - New York Times, Robin Marantz Henig
