The book is a critical analysis of the history of scientific racism and biological determinism, the belief that social and economic differences among human races, sexes, and classes are inheritable, inevitable, and natural. It challenges the idea that intelligence can be measured accurately and placed in a single, linear scale. The author refutes the arguments of those who support these theories, arguing that they are based on flawed methodologies, biased data, and unverifiable assumptions. Instead, he proposes that intelligence is multifaceted and cannot be quantified simplistically.
